Enamel ni varnish zisizwe ku nsinga z'umuringa cyangwa alumina kandi zigatunganywa kugira ngo zikore icyuma gikingira amashanyarazi gifite imbaraga zimwe na zimwe za mekanike, ubushobozi bwo kwihanganira ubushyuhe n'imiti. Ibi bikurikira birimo ubwoko bumwe na bumwe bwa enamel busanzwe muri Tianjin Ruiyuan.
Polyvinylformal
Resine ya Polyvinylformal ni imwe mu marangi ya kera cyane ya sintetike, yo mu 1940. Ubusanzwe yitwa FORVAR (yakozwe na Monsanto sosiyete ubu ikorwa na Chisso), ni umusaruro wa polycondensation wa formaldehyde na hydrolyzed polyvinyl acetate. PVF yoroshye cyane kandi ifite ubushobozi buke bwo kurwanya solvent. Ariko, ishobora kugira imikorere myiza iyo ikoreshejwe hamwe na resine ya phenolic, resine ya melamine formaldehyde cyangwa resine ya polyisocyanate.
Polyurethane
Polyurethane yakozwe mu Budage mu mpera z'imyaka ya 1940. Mbere, ubushyuhe bwari hagati ya 105°C na 130°C, ariko ubu yazamuwe igera kuri 180°C, kandi ikora neza kurushaho. Ikoreshwa cyane mu bikoresho by'amashanyarazi bifite voltage nke nka coils nziza, moteri, ibikoresho, ibikoresho byo mu rugo, nibindi bitewe nuko irangi ryiza cyane, irangi rinini kandi irahurwa neza.
Insinga za PU zishobora gushongeshwa zidakuyeho igitambaro.
Polyamide
Nanone yitwa nylon, ikunze gukoreshwa nk'ikoti ryo hejuru kandi ishobora kunoza amavuta, imiterere y'umubiri n'imikorere ya PVF, PU na PE enamel. Polyamide ishobora gukoreshwa nk'ibisubizo bya fibre cyangwa polymer zacitse. Ibikubiye muri molekile y'iyi polymer bituma umuti ugira ubukana bwinshi ku gipimo gito cy'ibintu bikomeye.
Polyester
Ingufu nziza za mekanike, gufatana neza kw'irangi, amashanyarazi meza, ubushobozi bwo kurwanya ubushyuhe, ubushobozi bwo guhangana n'ubushyuhe no kurwanya solvent; ikoreshwa mu byuma by'itumanaho by'ikoranabuhanga, moteri zifunganye, moteri nto, transformers zirwanya ubushyuhe, contactors, valve ya electromagnetic. Enamel ya polyester yoroshye ni umusaruro w'ibikomoka kuri aside terephtalike, glycerin na ethylene glycol, ikaba ari imiterere isanzwe ya enamel ya polyester ifite ubushyuhe bwa 155°C. (Mu gihe ubushyuhe bw'aya marangi burenga 180, izindi miterere nk'ubushyuhe buri hafi ya 155°C, keretse iyo ubuso busizwe na nylon).
Polyesterimide
Insinga za polyesterimide zishobora gushongeshwa zikoreshwa cyane ku nsinga za magneti ku byuma bitanga ingufu, transformateur nto, moteri nto, contactors, coils z'umuriro, coils za magnetique n'ibyuma by'imodoka. Izi coatings zikwiriye cyane cyane moteri nto z'amashanyarazi kugira ngo zihuze imiyoboro n'icyuma gikusanya. Insinga za magnetique zipfutse zifite ubushobozi bwo guhindagurika neza ndetse n'ubushobozi bwiza bwo kwangirika no gukora. Ifite ubushobozi bwiza bwa shimi, irwanya ubushyuhe kandi irwanya frigo.
Polyamide-imide
Enamel z'insinga za polyamide-imide zishobora gukoreshwa nk'ikoti ribiri cyangwa rimwe, ariko amahitamo yombi atanga imiterere myiza ya mekanike, kurwanya imiti, kurwanya ubushyuhe bwinshi, gukomera cyane no kurwanya umunaniro.
Polyimide
Igipimo cy'ubushyuhe: 240C
PI yagurishijwe na DuPont mu myaka ya 1960. Ni yo mvange y’umwimerere ifite ubushyuhe bwinshi. Ikoreshwa mu buryo bwa aside polyamike, igahindurwamo ubushyuhe igahinduka firime ihoraho. Ifite ubushyuhe buhamye, irwanya imirasire, imiti n’ubushyuhe bukabije. Icagaguye ＞500℃.
Enamel yifata ubwayo
Bitewe n'ibyo umukiriya akeneye mu gukora bitandukanye, ifite imiterere itandukanye n'uburyo butandukanye bwo kuyikoresha. Tianjin Ruiyuan ikoresha enamel zihuza zishingiye kuri epoxy, polyvinyl-butyral na polyamide zikoreshwa mu gushimangira ubwihisho. Zikoreshwa cyane cyane mu gutwikira insinga z'ibikoresho, insinga z'amajwi, indangururamajwi, moteri nto na sensor.
Insinga zose za rukuruzi zishobora gutegurwa hakurikijwe ibyo abakiriya bakeneye, Tianjin Ruiyuan, ikigo cyawe cy’umwuga gitanga ibisubizo ku nsinga za rukuruzi. Twandikire niba ufite ikibazo.
