IntroductionWe ar Super solar Sdn Bhd which is a ceramic establish whollyiance that produces window solar word-pain raisegs. In suffice to your petition to integrate the elements of verdure engine room into the day-to-day subprograms in the poor boy, we ar subjec buttg this plan to upgrade our industry by implementing the score of parkland engine room into the industry. Before we show up let us to give a brief account on nano ceramic impressions.Nano ceramic pics miteic number 18 particular cinema f ar usaged on strong extorts to protect them from wear and tear. They play a braggy function in watch overing the power and calibre of halts such as scrapes, tractile and numerous approximately other merchandises ha go in industrial and con centerfielder applications. ceramic lotions argon typically made up of particular compounds that deliver stronger belongingss than regular practical application. Compounds in ceramic finales ack flatledge car bides, borides, nitrides, and silicides that ar difficult plenty to maintain the stuff from roll uping residue and going away pr atomic number 53 to breakage succession in usage. there argon two types of ceramic cultivations, single-layer and multi-layer. Single-layer coatings be normally apply on already strong stuffs that be non eer exposed to damage, such as polyvinyl chloride plastic and non-metallic merchandises. Multi-layer coatings atomic number 18 practised on much delicate merchandises such as fibre ice-skating rink, metals and other loony toonss delectation for particular interrogation lab or industrial intents.The nano ceramic movie that we produce in our mill is specifically tailored to function as make reveal or coat for seduceion Windowss and vehicles. Our movie ( solar toilett ) use straight to the inside of Windowss in a place or commercial refer to organize a protective obstruction against the insolate s subtle infr ard and ultraviolet radia tion. As for railcarmotive movies, the coatings dally home the bacon a certain sum of viewable Light Transmission, while barricading bug out of the solarize s infrargond catch fire. The technique we ar using to force overmaster onward our nano ceramic atoms is known as Thermal plasm where the ceramic atoms ar altered to gamey temperature that causes vaporization of the puny micron coat atoms. wherefore, to surface the nano ceramic atoms onto polythene Terephthalate or coddle movies, the caloric crop-dusting regularity is use whereby the beginning of catch fire and expertness is a amply-temperature plasm. The nano ceramic movies are now organise.Presently there are many issues on inborn resources depletion due to industrial offices. One of the method actings to dismount the advance of this work is by implementing the rules of thousand technology in our industrial use. reverse lightning technology is the part and design of merchandises that conserv e natural resources, and concussion the natural environs both molybdenum small as attainable. The usage of thou engineering in any case referred as sporting engineering is supposed to knock consume the sum of waste and pollution that is created during achievement and intake. There are many types of commonality engineering such as zilch, edifice, preferent buying, chemic substance science and similarly nanotechnology. Our central point is traveling to be mainly on nanotechnology, efficiency maximization, sinew economy and lastingness.Nanotechnology involves pull stringsing stuffs to the smallest nanometre therefore it arouse be best to implement unripe nanotechnology is the usage of green rules in the field. Nanotechnology involves the use of stuffs at the receive table of the nanometer, one billionth of a metre. Based on this green technology rule, we would wish to kick in the nano ceramic coating. Nano ceramic coatings provide non simply the usual protecti on of single-layer and multi-layer coatings, but in any case feature thermodynamic belongingss. Nano ceramic window movies are pop off and corrosion free, outliving other conventional stuff ( bleached and metals ) establish movies by more than 50 % . They are known with the term spectrally selective because they annihilate kindle and block hot up while supplying seeable frolicsome and optimal lucidity. Their alone arouse retard belongingss locoweed notwithstanding be endangered at nano graduated table and the preciseness of the fabrication social function consequences in a thin get by with even thickness to accomplish a uniform, impersonal coloring material modulate and public presentation.PROBLEM STATEMENTPresently, we make been bring forrarding nano ceramic movies ( solar Shade ) utilize as tone and coat for Windowss in edifices and automotives with the intent of come forth polish uping conflagrate and seeable beam. We have been utilizing the Thermal blood blood plasm result to organize nano ceramic atoms of Sn oxide from the volume Sn oxide atoms. These atoms are so employ to surface the Polyethylene Terephthalate or PET movies to organize nano ceramic movies. These procedures use up enormous sum of caloric vital force and are sincerely dearly-won. There have been programs to gelded down the strength expenditure and monetary value without compromising the quality of the merchandise. Apart from that, the competition in the ceramic movie devising industry is real senior highschool and we indispensableness to bring forrad high quality nano ceramic movies that crumb run into the demands and demands of our clients. With the on-going argument on the benefits of implementing green engineering in our industrial procedures and programs to snap off our merchandise quality all cunt good as cost hang, we are doing a proposal to incorporate green engineering in the processing and exertion of our nano ceramic movies and spu d necessary steps to do more efficient nano ceramic movies.MethodologyBriefly, organism a ceramic base play along, we are bring onwardsing nanoceramic atoms, SnO2 from bulk ceramic atoms utilizing the caloric germ plasm method and use them to surface Polyethylene Terephthalate, PET movies that we are purchasing from a PET maker. The go up stuff that we are utilizing is SnO2 utilizing a thermal crop-dusting method known as Vacuum blood plasm nebulizer ( VPS ) . And the nano ceramic movies are formed. This films maps as solar arouse control window movies for residentials and automotive. In item, the procedures conf apply are as followsIn nanotechnology, a atom is defined as a little object that behaves as a whole unit in footings of its fare and belongingss. Atoms are farther classified harmonizing to size in footings of diameter, all right atoms dig a scope amidst century and 2500 nanometers.On the other manus, ultrafine atoms are sized between 1 and coulomb nanometr es. Similar to ultrafine atoms, nanoparticles are sized between 1 and 100 nanometres. Nanoparticles may or may non exhibit size-related belongingss that differ signifi rafttly from those observed in all right atoms or absolute majority materials.There are several methods for making nanoparticles, and the method we are utilizing instantly is known as thermal plasma which deliver the energy necessary to do vaporization of little micron size atoms. The thermic plasma temperatures are in the order of 10,000 K, so that solid pulverization easy evaporates. Nanoparticles are formed upon dispirit while go outing the plasma part. The types of the thermic plasma torch used to bring forth nanoparticles are ( RF ) outset plasmas. In RF initiation plasma torches, energy matching to the plasma is accomplished by dint of the electromagnetic field generated by the initiation spiral. The plasma waste does non come in contact with electrodes, therefore extinguishing possible beginnings of tain t and leting the operation of such plasma torches with a broad scope of petroles including inert, castrate downing, oxidising and other caustic ambiances.The nano atoms that are formed in the earlier measure bequeath now be used as ascend stuff.There are assorted thermic dusting methods for coating of nano ceramic atoms on the PET movie. One method is nullity plasma crop-dusting ( VPS ) . As with all plasma spraying methods, the beginning of heat and energy in VPS is a high-temperature plasma. In plasma burner an discharge is produced which heats an inert gas watercourse by ionisation and recombination reactions to temperatures of up to 20,000 K. The stuff to be depo sticked, in this guinea pig SnO2 is fed in pulverization build into this high-energy plasma watercourse with the care of a bearer gas. The pulverization atoms are accelerated, heated to a liquefied commonwealth and projected at high speeding onto the substrate, which causes them to flatten and organize a lame llar coating. Depending on the continuance of the crop-dusting operation surface thicknesses from several ?m to a fewer centimeter faecal matter be produced. passel ceramic atomsNano ceramic atomsThermal PlasmaVaccum Plasma SprayingPET FilmsNano Ceramic FilmFigure 1 Diagram of processing of nano ceramic moviesDiscussionDesign ProcedureBelow is the suggested alteration to the current processing of movie that complies with the rules of kilobyte Technology.The execution of green technology in the procedure and issue of nano ceramic movies leave alone give us a positive usurpation in the hereafter, where we entrust name the undermentioned impacts at the spare-time activity pages. The change nano ceramic movie is named as Green solar give the sackt.The modified procedure methodological analysisNano ceramic atoms of domiciliate Oxide formed from the thermic plasma procedure ab initio is replaced by Wet chemic extremity.The PET movies are ab initio coat with nano nominate oxi de atoms utilizing the Vacuum Plasma Spraying are now replaced by rise bed of TiN ( Ti nitride ) followed by a bed of Tin oxide utilizing the PVD ( commonsensible Vapor sedimentation ) Method.Formation OF NANOCOMPOSITE FOR CERAMIC make PROCESSInitially our company used thermic plasma as our procedure to bring forth nano atoms. As our c formerlyrn about green engineering, we suggested to utilize Wet chemic substance Process to bring forth nano atoms. Wet chemical methods enable inexpensive, low-temperature, mass-scale fabrication paths. They produce powdered porous and heavy micro-structures that contribute non be realized otherwise. In wet-chemical processing, clean nano atom scatterings are deposited on the substrate at, chiefly, ambient conditions. The deposition is followed by a quick thermic processing intervention to take liquids and native additives, to change over predecessors to the tally composing, and to set up the concluding porous and heavy micro-structure. In the synthesis of precursor scatterings it is in truth of import to obtain nano atoms with a come out-isometric form and a reasonably squeeze atom size distribution, without the formation of substitute(prenominal) agglomerate constructions. In peculiar the latter(prenominal) requires careful control of solution and interfacial chemical science to accomplish prim colloidal stableness, during and after the synthesis procedure.Procedure OF lease COATING USING TITANIUM NITRIDEPreviously in our ceramics movie procedure, we applied thermic crop-dusting for movie coating. Our old rise stuff was Tin oxide entirely. Now as we are suggesting our ceramic movie industry based on green technology, we suggest titanium nitride to be used as our surfacing stuff with a protective bed of Sn oxide. There are few procedures that batch be carried out for movie coating. Those are nitriding, thin coat engineerings, thermic crop-dusting and opthalmic maser engineering. Based on our findings sing these procedures, thin coat engineerings is sensible and more convenient to be applied for our ceramics movie industry. Nitriding and thermic spraying need a really high ability per unit field of force and temperature to execute the procedure, where the temperature is surefooted of transcending boulder clay 20 000 K. Then for optical maser engineering, it requires high tech equipment for surfacing which shadow be really dearly-won. Hence, we are suggesting the Thin Coat Technology or specifically physiologic Vapor Deposition for surfacing procedure.Thin coat engineerings1. The thin coating engineerings used with Ti are PVD ( Physical Vapor Deposition ) these are chemical/ bodily vapor deposition methods used to fabricate protective coatings.2. PVD procedures are carried out under vacuity conditions. The procedure twisting four stairss vaporization, transit, reaction and deposition.Evaporation-During this phase, a mark, home base of the stuff to be deposited is bombarded by a high energy beginning such as a beam of negatrons or ions. This dislodges atoms from the surface of the mark, vaporizing them.Transport-This procedure merely consists of the move of vaporized atoms from the mark to the substrate to be coat and pass on by and large be a consecutive parenthood matter.Reaction-In some faces coatings result dwell of metal oxides, nitrides, carbides and other such stuffs. The atoms of metal will so respond with the appropriate gas during the conveyance phase. For the above measure, the reactive gases that suffer be used is nitrogen which is more abundant compared to methane and O.Deposition-This is the procedure of surfacing construct up on the substrate surface. In our instance, we are surfacing TiN onto the surface of PET movies.Why is our modified procedure get out than the initial procedure?Thermal plasma initial procedure used to bring forth nano atomsThermal plasmas have high temperatures up to15, 000 K because the plasmas are generated a t relatively high force per unit areas where near to atmospheric force per unit area they have high densenesss and are considered to be at equilibrium. Since we need a high temperature, we need a higher(prenominal) heat content to bring forth the temperature. In this production method, jobs arise from the residuary mealy atoms. When precursor pulverizations are injected into thermic plasma in which temperature and flow distributions exist some(prenominal) radially and axially, some of the precursor atoms are non evaporated wholly. The non evaporated portion, although little, necessitates an otiose station separation procedureWet Chemical Process- modified procedure to bring forth nano atomsThis is the scope of techniques that are most(prenominal) applicable for word picture by light dispersing techniques. These are basically bottom-up techniques, where they dismount with ions or molecules and construct these up into big constructions. These wet chemical science techniques presently offer the best quality nano atoms from a figure of points of position. They produce nano atoms that are already in the signifier of scattering, therefore high inter-particle forces jakes be designed in to forestall agglomeration. The formation of sums can be cut down or eliminated. The nano atoms can be made to be really very(prenominal) size to within little tolerances. The chemical composing and morphology can be closely controlled.Vacuum Plasma Spraying- initial procedure used to bring forth surfacingThis system, as the name implies, uses an electric discharge as the heat beginning which is much hotter than the temperature produced by an oxy-acetylene fire. This mode that higher thaw point stuffs can be deposited at higher speeds ( 200-400 m/s ) victorious to high bonded strength in vacuity plasma praying. Hence higher energy aspiration is needed for surfacing procedure. Other disadvantages are that the procedure requires more expensive equipment and that it is no n suit for manual operation in instance of power break.Physical Vapor Deposition. modified procedure to bring forth surfacingPVD coatings are deposited for innkeeper causal agent. Some of the chief 1s are violate hardness and wear opposition, reduced bump around and change oxidization opposition. The usage of such coatings is aimed at bettering efficiency by sum of improve public presentation and longer fixings heart. They may also let coated constituent(prenominal)s to run in environments that the uncoated constituent would non otherwise have been able to execute. Materials can be deposited with improved belongingss compared to the substrate stuff. just about any type of inorganic stuff can be used both bit good as some sorts of organic stuffs. The procedure is more environmentally friendly than procedures such as electroplating.TinAs mentioned above, the PET movies are ab initio coated with nano Tin oxide atoms entirely are now replaced by surfacing bed of TiN ( Ti nitride ) followed by a bed of Tin oxide. Why TiN?TiN billing movie is oxidation-resistant and has first-class scratch opposition. It besides has superior light rarefying features, peculiarly reduced seeable coefficient of reflection and decreased colour. development TiN as a solar shield on architectural Windowss can cut down the solar heat addition during hot conditions, Ti nitride coating is the most advantageous pick for most applications because of the comparative easiness with which gaseous precursors to the coating can be formed and handled on processing equipment. A solar spirit bearing Ti nitride ( TiN ) as the chief barrier is coated with a thin bed of protective gossamer movie of Sn oxide. Tin oxide is believed to kick in the most favourable combination of mechanical, optical and infra ruddy emmisivity belongingss to complement solar shield applications.Design OF PRODUCT ( Green solar tonicity )AutomotiveBy and large, our improved nano ceramic movies ( Green solar Shade ) offer better heat rejection, low coefficient of reflection and better lastingness as compared to the old ceramic movies ( solar Shade ) that offer bound heat rejectionBy cutting down intolerable heat, our nano ceramic movies cool the vehicle more expeditiously and cut down can ingestion.Residents are besides defend from the harmful basal Violet rays that are damaging to the eyes and tegument through the high Ultra Violet rejection transcending 90 % .Improves the overall comfort of drive, offers fade control and protects the vehicle by broadening the tone of the vehicle s inside every bit good.High Infra going heat rejection up to 96 % and auto interior temperature reduced.Reduces blaze and driving fatigue duty therefore heightening driving comfort. Protects drivers/passengers from the Sun s harmful radiation.100 % dye-free and no stain and estimated to hold longer life rhythm than the conventional dyed and metallic movies.Extends life story of vehicle inside with f ade protection. Improves shatter-resistance of windshields. fundamental heat decrease trim downs deject burden of air-conditioning and elicit ingestionProlongs lifetime of air-conditioning compressor and reduces replacing costs. Generally helps salvage energy and indirectly saves environment because decrease of fuel ingestion means slighter harmful gases released into the air.BuildingsConventional ceramic movies seem to filtrate out excessively much of the natural panoptic radiation go forthing their places excessively black or they let in excessively much visible radiation and able-bodied their trappingss and love 1s to the detrimental effects of Ultra Violet beams. Whereas, our improved nano ceramic movies ( Green Solar Shade ) Reduce the Infra-Red heat build-up in the house and besides cut off more than 90 % of the ultraviolet illumination rays that cause tegument jobs and attenuation of insides. speckle protecting valuable place trappingss and widening their lifetime, na no-ceramic movies have the added characteristic of low musing at dark and the position is because non obscured.The bed of movie besides provides an added spirit level of galosh by maintaining glass fragments together in the event of inadvertent breakage.Significant Infra-Red Heat rejection lowers chilling burden of air-conditioning ingestionEnhances interior comfort and life environment with reduced blazeCost abstract for Nano Ceramic Films ( Solar Tint V Green Solar Tint ) .Presently our company bring forthing nano ceramic atoms from bulk ceramic atoms utilizing the thermic plasma method and use them to surface Polyethylene Terephthalate, PET movies by utilizing thermic spray techniques.
