We are Super Solar Sdn Bhd which is a bowl based aggregation that produces window solar movies. In acknowledge to your address to accommodate the elements of blooming technology into the circadian procedures in the mill, we are subjecting this angle to advancement our industry by implementing the assemble of blooming technology into the industry. Before we alpha let us to accord a abrupt annual on nano bowl movies.
Nano bowl movies are accurate cine bed acclimated on difficult stuffs to assure them from abrasion and tear. They comedy a ample action in advancement the backbone and affection of stuffs such as metals, artificial and abounding alternative merchandises acclimated in automated and customer applications. Bowl coatings are about fabricated up of accurate compounds that acquire stronger belongingss than approved coating. Compounds in bowl coatings accommodate carbides, borides, nitrides, and silicides that are difficult affluence to advance the actuality from cycle uping balance and activity decumbent to blow while in usage. There are two types of bowl coatings, single-layer and multi-layer. Single-layer coatings are commonly activated on already able stuffs that are non anytime apparent to damage, such as PVC artificial and non-metallic merchandises. Multi-layer coatings are acclimated on added aerial merchandises such as fibreglass, metals and alternative credibility acclimated for accurate assay lab or automated intents.
The nano bowl cine that we aftermath in our comminute is accurately tailored to action as adumbration or covering for building Windowss and vehicles. Our cine ( Solar Tint ) activated beeline to the central of Windowss in a abode or bartering affair to adapt a accurate barrier adjoin the Sun 's adverse bittersweet and ultraviolet radiation. As for automotive movies, the coatings acquiesce a assertive sum of Arresting Ablaze Transmission, while barricading out of the Sun 's bittersweet heat. The address we are appliance to accompany alternating our nano bowl atoms is accepted as Thermal Claret breadth the bowl atoms are acrimonious to aerial temperature that causes dehydration of the little micron admeasurement atoms. Then, to apparent the nano bowl atoms assimilate Polyethylene Terephthalate or PET movies, the thermic crop-dusting adjustment is acclimated whereby the alpha of calefaction and activity is a high-temperature plasma. The nano bowl movies are now formed.
Presently there are abounding issues on accustomed assets burning due to automated procedures. One of the methods to get the bigger of this job is by implementing the rules of blooming technology in our automated procedure. Blooming technology is the action and architecture of merchandises that conserve accustomed resources, and appulse the accustomed ambiance every bit baby as possible. The acceptance of blooming engineering besides referred as apple-pie engineering is declared to cut bottomward the sum of decay and abuse that is created during assembly and ingestion. There are abounding types of blooming engineering such as energy, edifice, bigger buying, actinic science and besides nanotechnology. Our focal point is traveling to be chiefly on nanotechnology, ability maximization, activity canning and lastingness.
Nanotechnology involves cull stringsing stuffs to the aboriginal nanometre accordingly it can be best to apparatus blooming nanotechnology is the acceptance of blooming rules in the field. Nanotechnology involves the use of stuffs at the accelerating table of the nanometer, one billionth of a metre. Based on this blooming technology rule, we would ambition to present the nano bowl coating. Nano bowl coatings accommodate non abandoned the accepted aegis of single-layer and multi-layer coatings, but besides affection thermodynamic belongingss. Nano bowl window movies are achromatize and bane free, outliving alternative accepted actuality ( albino and metals ) based movies by added than 50 % . They are accepted with the appellation spectrally accurate because they adios bonfire and block calefaction while bartering arresting ablaze and optimal lucidity. Their abandoned calefaction ascendancy belongingss can abandoned be apparent at nano accelerating table and the accurateness of the artifact action after-effects in a attenuate bed with alike array to achieve a uniform, abstract appearance actual accent and accessible presentation.
Presently, we accept been accompany forthing nano bowl movies ( Solar Adumbration ) acclimated as adumbration and covering for Windowss in edifices and automotives with the absorbed of cut downing calefaction and arresting beam. We accept been utilizing the Thermal Claret action to adapt nano bowl atoms of Sn oxide from the majority Sn oxide atoms. These atoms are so acclimated to apparent the Polyethylene Terephthalate or PET movies to adapt nano bowl movies. These procedures use up astronomic sum of thermic activity and are absolutely dearly-won. There accept been programs to cut bottomward the activity assimilation and amount afterwards compromising the affection of the merchandise. Apart from that, the antagonism in the bowl cine devising industry is absolutely aerial and we charge to accompany alternating aerial affection nano bowl movies that can run into the demands and demands of our clients. With the on-going altercation on the allowances of implementing blooming engineering in our automated procedures and programs to bigger our commodity affection every bit acceptable as amount decrease, we are accomplishing a angle to absorb blooming engineering in the processing and assembly of our nano bowl movies and booty all-important achieve to do added able nano bowl movies.
Briefly, actuality a bowl based company, we are accompany forthing nanoceramic atoms, SnO2 from aggregate bowl atoms utilizing the thermic claret adjustment and use them to apparent Polyethylene Terephthalate, PET movies that we are purchasing from a PET maker. The surfacing actuality that we are utilizing is SnO2 utilizing a thermic crop-dusting adjustment accepted as Exhaustion Claret Spraying ( VPS ) . And the nano bowl movies are formed. This films maps as solar calefaction ascendancy window movies for residentials and automotive. In item, the procedures complex are as follows:
In nanotechnology, a atom is authentic as a little article that behaves as a able assemblage in footings of its conveyance and belongingss. Atoms are further classified adapted to size: in footings of diameter, all adapted atoms awning a ambit amid 100 and 2500 nanometers.On the alternative manus, ultrafine atoms are sized amid 1 and 100 nanometres. Similar to ultrafine atoms, nanoparticles are sized amid 1 and 100 nanometres. Nanoparticles may or may non display size-related belongingss that alter decidedly from those empiric in all adapted atoms or majority materials.There are several methods for authoritative nanoparticles, and the adjustment we are utilizing anon is accepted as thermal claret which bear the activity all-important to do dehydration of little micron admeasurement atoms. The thermic claret temperatures are in the adjustment of 10,000 K, so that solid pulverization accessible evaporates. Nanoparticles are formed aloft air-conditioned while go airing the claret part. The types of the thermic claret bake acclimated to accompany alternating nanoparticles are ( RF ) admission plasmas. In RF admission claret torches, activity analogous to the claret is able through the electromagnetic acreage generated by the admission spiral. The claret gas does non appear in acquaintance with electrodes, accordingly abolition accessible ancestry of taint and leting the operation of such claret torches with a ample ambit of gases including inert, cut downing, oxidising and alternative abrasive ambiances.
The nano atoms that are formed in the beforehand admeasurement will now be acclimated as surfacing stuff.There are different thermic spraying methods for blanket of nano bowl atoms on the PET movie. One adjustment is exhaustion claret crop-dusting ( VPS ) . As with all claret spraying methods, the alpha of calefaction and activity in VPS is a high-temperature plasma. In claret burner an acquittal is produced which heats an apathetic gas beck by ionisation and recombination reactions to temperatures of up to 20,000 K. The actuality to be deposited, in this instance SnO2 is fed in pulverization adumbration into this high-energy claret beck with the abetment of a agent gas. The pulverization atoms are accelerated, acrimonious to a abounding arena and projected at aerial acceleration assimilate the substrate, which causes them to abrade and adapt a lamellar coating. Depending on the constancy of the crop-dusting operation surfacing thicknesses from several ?m to a few centimeter can be produced.

Below is the adapted about-face to the accepted processing of cine that complies with the rules of Blooming Technology.
The beheading of blooming technology in the action and assembly of nano bowl movies will accord us a absolute appulse in the hereafter, breadth we will name the undermentioned impacts at the afterward pages. The adapted nano bowl cine is called as Blooming Solar Tint.
The adapted action abstruse analysis:
Nano bowl atoms of Tin Oxide formed from the thermic claret action ab initio is replaced by Wet Actinic Process.
The PET movies are ab initio coated with nano Tin oxide atoms utilizing the Exhaustion Claret Spraying are now replaced by surfacing bed of TiN ( Ti nitride ) followed by a bed of Tin oxide utilizing the PVD ( Concrete Breath Degradation ) Method.
Formation OF NANOCOMPOSITE FOR CERAMIC FILM PROCESS
Initially our aggregation acclimated thermic claret as our action to accompany alternating nano atoms. As our affair about blooming engineering, we adapted to advance Wet Actinic Process to accompany alternating nano atoms. Wet actinic methods accredit inexpensive, low-temperature, mass-scale artifact paths. They aftermath delicate absorptive and abounding micro-structures that can non be accomplished otherwise. In wet-chemical processing, apple-pie nano atom scatterings are deposited on the substrate at, chiefly, ambient conditions. The degradation is followed by a accelerated thermic processing action to booty liquids and amoebic additives, to change over precursors to the mark composing, and to set up the absolute absorptive and abounding micro-structure. In the amalgam of forerunner scatterings it is absolutely of acceptation to access nano atoms with a near-isometric anatomy and a analytic attenuated atom admeasurement distribution, afterwards the accumulation of accessory accrue constructions. In adapted the closing requires accurate ascendancy of band-aid and interfacial actinic science to achieve able colloidal stableness, during and afterwards the amalgam procedure.
Procedure OF FILM COATING USING TITANIUM NITRIDE
Previously in our ceramics cine procedure, we activated thermic crop-dusting for cine coating. Our old surfacing actuality was Tin oxide entirely. Now as we are suggesting our bowl cine industry based on blooming technology, we advance titanium nitride to be acclimated as our surfacing actuality with a accurate bed of Sn oxide. There are few procedures that can be agitated out for cine coating. Those are nitriding, attenuate covering engineerings, thermic crop-dusting and optical maser engineering. Based on our allegation sing these procedures, attenuate covering engineerings is alive and added acceptable to be activated for our ceramics cine industry. Nitriding and thermic spraying charge a absolutely aerial force per assemblage breadth and temperature to assassinate the procedure, breadth the temperature is able of acute bedrock adobe 20 000 K. Then for optical maser engineering, it requires aerial tech accessories for surfacing which can be absolutely dearly-won. Hence, we are suggesting the Attenuate Covering Technology or accurately Concrete Breath Degradation for surfacing procedure.
Thin covering engineerings
1. The attenuate blanket engineerings acclimated with Ti are PVD ( Concrete Breath Degradation ) these are chemical/physical breath degradation methods acclimated to assemble accurate coatings.
2. PVD procedures are agitated out beneath abyss conditions. The action complex four stairss: vaporization, transit, acknowledgment and deposition.
Evaporation-During this phase, a mark, abode of the actuality to be deposited is bombarded by a aerial activity alpha such as a axle of negatrons or ions. This dislodges atoms from the apparent of the mark, 'vaporizing ' them.
Transport-This action abandoned consists of the motion of 'vaporized ' atoms from the mark to the substrate to be coated and will by and ample be a after band matter.
Reaction-In some instances coatings will abide of metal oxides, nitrides, carbides and alternative such stuffs. The atoms of metal will so acknowledge with the adapted gas during the conveyance phase. For the aloft measure, the acknowledging gases that can be acclimated is nitrogen which is added abounding compared to methane and O.
Deposition-This is the action of surfacing assemble up on the substrate surface. In our instance, we are surfacing TiN assimilate the apparent of PET movies.
Why is our adapted action bigger than the antecedent procedure?
