Enamels bụ varnish e ji ọla kọpa ma ọ bụ waya alumina kpuchie ma ghee ya ka ọ bụrụ ihe mkpuchi eletriki nwere ike mekaniki, ihe na-eguzogide okpomọkụ na ihe ndị na-eguzogide kemịkal. Ihe ndị a gụnyere ụfọdụ ụdị enamel a na-ahụkarị na Tianjin Ruiyuan.
Polyvinylformal
Resin Polyvinylformal bụ otu n'ime agba ndị kacha ochie e ji aka mee, nke malitere n'afọ 1940. A na-akpọkarị ya FORVAR (nke ụlọ ọrụ Monsanto mepụtara na mbụ, Chisso na-emepụta ugbu a), ọ bụ ngwaahịa polycondensation nke formaldehyde na hydrolyzed polyvinyl acetate. PVF dị nro ma nwee ike iguzogide ihe mgbaze na-adịghị mma. Agbanyeghị, ọ nwere ike ịrụ ọrụ nke ọma ma e jiri ya na resin phenolic, resin melamine formaldehyde ma ọ bụ resin polyisocyanate.
Polyurethane
E mepụtara Polyurethane na Germany na ngwụcha afọ 1940. Na mbụ, ọkwa okpomọkụ dị n'etiti 105°C na 130°C, mana ugbu a, emeziwanyela ya ruo 180℃, ma na-arụkwa ọrụ ka mma. A na-ejikarị ya eme ihe n'ọtụtụ ngwaahịa eletriki na-enweghị voltaji dị ka coils ziri ezi, moto, ngwa, ngwa ụlọ, wdg n'ihi agba ya dị mma, oke mkpuchi ya na ike ịgbasa ya kwụ ọtọ.
Enwere ike ịgbanye waya PU na-enweghị iwepụ ihe mkpuchi ahụ.
Polyamide
A na-akpọkwa ya naịlọn, a na-ejikarị ya eme ihe dị ka ihe mkpuchi elu ma nwee ike ime ka mmanụ dịkwuo mma, njirimara anụ ahụ na nke mekaniki nke PVF, PU na PE enamel. Enwere ike iji Polyamide mee ihe dị ka ngwọta nke eriri dị mfe ma ọ bụ polymers iberibe gbajiri agbaji. Ihe siri ike dị na molekul nke polima a na-eme ka ngwọta ahụ nwee viscosity dị elu na ọdịnaya siri ike dị ala.
Polyester
Ike igwe dị mma, njikọta ihe osise agba, ezigbo eletriki, iguzogide kemịkalụ, nkwụsi ike okpomọkụ na iguzogide ihe mgbaze; eji ya na kọlụm ọkụ nkwukọrịta eletrọnịkị, moto ndị a na-etinye n'ime mmiri, obere ihe na-emepụta ihe, transformers na-eguzogide okpomọkụ, contactors, na valvụ electromagnetic. Enamel polyester kachasị mfe bụ ngwaahịa mmeghachi omume nke terephthalic acid, glycerin na ethylene glycol nke bụ ihe mejupụtara 155°C nke polyester enamel. (Ọ bụ ezie na ndụ okpomọkụ nke agba ndị a karịrị 180, ihe ndị ọzọ dị ka ihe na-eme ka okpomọkụ dị nso na 155°C, ọ gwụla ma e jiri naịlọn kpuchie elu ya).
Polyesterimide
A na-ejikarị waya polyesterimide nke a na-agbaze agbaze eme ihe n'ọtụtụ ebe na waya magnet maka relay, obere transformers, obere moto, contactors, igniting coils, magnet coils na autocoils. Mkpuchi ndị a dabara nke ọma na obere moto eletriki iji jikọọ windings na collector. Waya magnet a kpuchiri ekpuchi nwere ezigbo ike ịgbatị yana ezigbo dielectric na mechanical characteristic. O nwere ezigbo kemịkalụ, ezigbo ike iguzogide okpomọkụ na iguzogide refrigerants.
Polyamide-imide
Enwere ike iji waya Polyamide-imide mee ihe dị ka mkpuchi abụọ ma ọ bụ otu, mana nhọrọ abụọ a na-enye ezigbo ihe eji arụ ọrụ, iguzogide kemịkalụ, iguzogide okpomọkụ dị elu, ike nrụgide dị elu na iguzogide ike ọgwụgwụ.
Polyimide
Ọkwa Okpomọkụ: 240C
DuPont mere ka PI bụrụ ihe a na-ere ahịa na 1960. Ọ bụ ihe mkpuchi organic kachasị elu nke nwere okpomọkụ. E tinyere ya n'ụdị ihe ngwọta polyamic acid, nke a na-agbanwe na okpomọkụ ka ọ bụrụ ihe nkiri na-aga n'ihu. Ọ nwere ezigbo nkwụsi ike okpomọkụ, na-eguzogide radieshon, kemịkalụ na okpomọkụ cryogenic. Bee ya na ⼞500℃.
Enamel nke na-arapara onwe ya
Dabere na mkpa mmepụta dị iche iche nke onye ahịa, ọ nwere njirimara dị iche iche na ọtụtụ ojiji dị iche iche. Tianjin Ruiyuan na-eji enamel ndị na-ejikọta onwe ha nke dabere na epoxy, polyvinyl-butyral na polyamide ka eji mee ka winding ahụ kwụsie ike. A na-ejikarị ha ekpuchi eriri ngwa egwu, eriri olu, igwe okwu, obere moto na sensọ.
Enwere ike ime waya magnet niile dịka iwu si dị site na ihe ndị ahịa chọrọ, Tianjin Ruiyuan, onye na-enye ọrụ waya magnet ọkachamara gị. Biko nweere onwe gị ịkpọtụrụ anyị ma ọ bụrụ na ị nwere ajụjụ ọ bụla.
