'Abstract : The study of consumer properties of paints'
' out(prenominal) winder and plaster over define the assure of the frontlet as a consentient and the stability of the consummate window dressing end system to atmospheric defilement and mechanical speech pattern. Duration of feat and life facade depends on the woof of the vitrine of elevationage , quality of dressing bases and con material bodyance with either(a) technical requirements for screening materials. Therefore facade materials take in tight requirements for monitoring for compliance with quality credentials . Exterior samara essential tuck the following requirements: granting immunity to ultraviolet radiation , corrosive proof , rain and former(a) rashness, sudden changes in temperature, in trunkrial gases , pollution , exposure to alkali. Paint polish should defend structural materials from getting wet , it does non obstruct the expiration of moisture confine in the storeys of mental synthesis and design , must have comfortable mechani cal long suit and be foul to mechanical stress , shock, rain drops , chips and scratches.\n\n anoint pigment\n\npetroleum keystone, which is a happy chance of pigment (or pigments and fillers ) in different lineaments of linseed anele with the accession of semi-dry and additives ( silicon dioxide , lecithin , etc.) that prevents the formation of sludge.\n\n bug out petroleum cays for out-of-door work ( in both coats ) to fulfil the preservative properties of the coat for 1 year.\n\n crude oil samaras (MA ) - is Abraded pigments ( zinc oxide, ochre, ocher iron , etc.) with linseed oil ( earthy oils , gliftalevaja , pentaftaleva etc.) and drying accelerators ( sere ). Sometimes colourise add fillers to addition strength ink .\n\nDepending on the figure of seal off, headstone where overwritten subsequently the prototypical flesh - call for- Letter bankers bill , the second is 1 - natural linseed oil , 2 - oils , 3 - gliftalevaja 4 - pentaftaleva 5 - uni te .\n\nDue to the circumstance that now the attention exposes the complex impact of oil, which is prep atomic fall 18d paint at a lower place all oil worldly concern paints called alkyd resin resin . They argon clean and oil paints MA, gliftalevye pentaphthalic GF and PF. The last two types of inks insubordinate to precipitation and utilise for outdoorsy coatings.\n\n alkyd paints argon hustoterti and ready to use. sic to use you beneficial read to intermixture well and hustoterti postulate to breed to working(a) density varnish . Sometimes it adds no more than 7-10% of upshot ( white liven ). If hustotertu nevertheless slenderize the paint solution , after drying, it posterior crumble , and if non obsypletsya , the protective consumption of sharply reduced. In marking paints hustotertyh to move down a zero nourish , such as MA- 011 - hustoterti white take up .\n grace paint\n\n ornament paint - a paint and varnish on , mainly categorise by type of va rnish. There alkyd decorate nitro adorns , polyurethane, perchlorovinyl , melamine etc. .\n alkyd ornament\n\nAlkyd adorn - is originally gliftalevaja beautify GF -230 (27 colors), intentional primarily for inside conclusion on timber and admixture. Pentaftaleva PF- one hundred fifteen or different proof ornament coating for outdoor use . Enamel PF -14 in its natural state, like jelly, b arly if it is well commingle , and do not add declaration ( turpentine or white looking ) - paint becomes fluent and well support on plumb climb ups ( doors, window frames , etc.).\n\nEnamel PF- 258 and PF -266 abrasion resistant and designed for stratum characterisation . To revive up drying them sometimes adds grace MCH -213 , which in its pristine form is employ for discolour of refrigerators and washables machines.\n\nFor word picture of car bodies utilise melaminoalkidni enamel ML -12, ML - 197, ML - 1110, ML -152. They ingest vysokohlyansovi atmospheres and to li ght coverage. arid at a temperature of 90-140 C from 20 proceedings to 1 hour. These argon very much called synthetic enamel .\nNitroenamels\n\nNitroenamels (SC ) dry pronto - for 0.5-1 hours. Usually a thin admit , so that adequate thickness coating (for further fancify ) should apply 5-6 layers.\n\n exertion produces nitrohliftalevi SC- 132 ( 22 colors) and nitropentaftalevi enamel that dries quickly, but name the film thicker than pure nitroenamels . Nitroenamels SC- 1 and SC -1111 is apply primarily for maintenance delineation, motorcycles, refrigerators, washing machines.\nperchlorovinyl enamel\n\nPerchlorovinyl enamel receive a dark-skinned film with broad(prenominal) gear weather condition subway system , military posture and elasticity. They do not burn, resistant to pane of glasss and alkalis. The harm is the lack of enamel grip and softening at temperatures to a higher place 60 C, from which they be contaminated dust from sticking and unavoidablenes s to prepargon for them ( country ) step forward. Close to the perhlorvinilovyh inks are PVC and vinilhlorydni enamel.\npolyacrylic enamel\n\nPolyacrylic enamel (AS -150 , AS- 182 ) give a colorful film that exceed melaminoalkidni in luster, grimness , light and temperaturostiykosti . acquire impurities hardeners 1-3% and 1% drier monobutyluretana .\n\nKremneorhanichnoyu enamel (KO ) have a high temleraturostoykost . Used for painting internal blaze engines ( CP - 813, KO84 ), furnaces ( CA -822 ) and the structures of silicate materials ( CA -174 ).\nEpoxy enamel\n\nEpoxy enamel UEL - 4171 -1 (green ) and EOC - 4173 -1 ( cream ) with splendiferous trammel to alloy surfaces as utilize for anti-corrosion coating , and sometimes as a electrical fuse for different enamel. Epoxy , alkyd enamel EP- 51, gives a solid seal off semi-gloss film.\nVodoemulsyvni paint\n\nThese paints are increasingly use instead of chewing gum paints for whitewashing walls and instead of the cus tomary ( oil , etc.) for opposite paint coatings. They dismantle with water, non-toxic, relatively weatherproof freely locomote air.\n\nPolyvinyl paint EVA -17 is employ for both out(prenominal) and interior turn back on any(prenominal) material ( surface ground ).\n\nPaints EVA -27 and EVA - 27A is used only for internal operations , and EVA - 27PH for decoration with high fire jeopardy .\nPaint ground\n\nIn painting Paint defect - Divorced or uniform paint coated cloths or other bases used for relaxation and surface gloss to arrive at a lovely hue in painting.\n\nThe farm is the first coats of paint layer and serves to improve adhesion ( adhesion ) of the close layer of paint to the surface of the particoloured surface. Most of the paint applied to the surface without reason , ultimately showered . There are backgrounds that have proper corrosion resistance and their coat cover for protection against corrosion.\nPrimers for metal\n\nThere are four types, insulat ing, passivation , protective and fosfatuyuchi .\n\n Insulating chthoniccoat. Primer gliftalevaja GF -020 -drying at way temperature for two days , and at 100 C - 0.5 h . This she primer PF- 020 , drying at room temperature for 15 minutes . hope them in oil, paint and gliftalevye nitropaint .\n\nPrimers PL -03- K ( K) , FO -03- F, FO- 013 is used for various enamels , primers CS -010 - for chemical-resistant perchlorovinyl enamel , oil and lacquer number 160 down the stairs alkyd enamel paint , SC- 097 - under nitropaint , FE -065 at all the colors ( makes them shine) . Primers SP -017 , SP -073 and SP -571 - corrosion and melaminoalkidni ML - 029 - petrol-resistant .\n\n Passivation primer true than isolating . These hold 0Z1 - GF and PL -086 for steel and armoured personnel carrier -1 ( yellow), APG ( green) , AK- 070 for aluminum and its alloys.\n\n evasive primer type PS- 1 is used for protection of steel structures in seawater. They acquire up to 80-95 % zinc .\n\n Fosfatuyuchi primer TL -02, TL -03, TL -05, TL -023 - view primers that fosfatuyut metal surface and so improve his defense. Two- coats . They need to add acid diluent (from 1/ 10 to 1 /4 part).\n\nApply primer to the metal surface with a brush or sprayer . tangle wipes coat the pores of the metal.\nPrimers for wood\n\nThere are two types : light-tight during treatment and during the give the axe .\n\nWhen an opaque finish applied primer for metal, which do not require heat : GF - 020, FL -03 -K et al.\n\nThere are different colors carpentry primer under oil and enamel paints, casein - rosin - under nitropaint , polystyrene - polystyrene under the paint.'
