ʻO nā Enamels he mau varnish i uhi ʻia ma luna o ka ʻili o nā uea keleawe a alumina paha a hoʻōla ʻia e hana i kahi ʻili insulation uila me kekahi ikaika mechanical, kūpaʻa wela a me nā waiwai kūpaʻa kemika. ʻO kēia kekahi mau ʻano enamel maʻamau ma Tianjin Ruiyuan.
Polyvinylformal
ʻO ka resin Polyvinylformal kekahi o nā pena synthetic kahiko loa, mai ka makahiki 1940. ʻO ka maʻamau i kapa ʻia ʻo FORVAR (i hana mua ʻia e ka hui Monsanto a i hana ʻia i kēia manawa e Chisso), he huahana polycondensation ia o ka formaldehyde a me ka polyvinyl acetate hydrolyzed. He palupalu ka PVF a he haʻahaʻa kona kūpaʻa solvent. Eia nō naʻe, hiki iā ia ke hoʻokō i ka hana maikaʻi aʻe ke hoʻohana ʻia me ka resin phenolic, melamine formaldehyde resin a i ʻole polyisocyanate resin.
Polyurethane
Ua hoʻomohala ʻia ka Polyurethane ma Kelemania i ka hopena o nā makahiki 1940. I ka wā mua, ʻo ka pae wela ma waena o 105°C a me 130°C, akā i kēia manawa ua hoʻomaikaʻi ʻia i 180℃, a ʻoi aku ka maikaʻi o ka hana. Hoʻohana nui ʻia ia i nā huahana uila haʻahaʻa-voltage e like me nā wili kikoʻī, nā motika, nā mea kani, nā lako hale, a me nā mea ʻē aʻe ma muli o kona hoʻoluʻu maikaʻi loa, ka wikiwiki o ka uhi ʻana a me ka hiki ke kūʻai pololei ʻia.
Hiki ke hoʻopili ʻia ka uea PU me ka wehe ʻole ʻana i ka uhi.
Polyamide
Ua kapa ʻia hoʻi ʻo nylon, hoʻohana pinepine ʻia ia ma ke ʻano he topcoat a hiki ke hoʻomaikaʻi i ka lubricating, nā waiwai kino a me nā mechanical o PVF, PU a me PE enamel. Hiki ke hoʻohana ʻia ka Polyamide ma ke ʻano he mau hopena o ka fiber maʻalahi a i ʻole nā polymers ʻāpana haki. ʻO nā ʻike paʻa o ka molekala o kēia polymer e ʻae i ka hopena e loaʻa kahi viscosity kiʻekiʻe ma kahi ʻike solids haʻahaʻa.
Polyester
ʻO ka ikaika mechanical maikaʻi, ka hoʻopili ʻana o ka ʻili pena, ka uila maikaʻi loa, ke kūpaʻa kemika, ke kūpaʻa wela a me ke kūpaʻa solvent; hoʻohana ʻia i nā wili kukui kamaʻilio uila, nā motika submersible i hoʻopaʻa ʻia, nā micro-generators, nā mea hoʻololi pale wela, nā mea hoʻopili, ka valve electromagnetic. ʻO ka enamel polyester maʻalahi loa ka huahana hopena o ka terephthalic acid, glycerin a me ka ethylene glycol he mea maʻamau ia o kahi enamel polyester papa 155°C. (ʻOiai ʻoi aku ka lōʻihi o ke ola wela o kēia mau pena ma mua o 180, ʻoi aku ka kokoke o nā waiwai ʻē aʻe e like me ka haʻalulu wela i 155°C, ke ʻole ka uhi ʻia ʻana o ka ʻili me ka nylon).
Polyesterimide
Hoʻohana nui ʻia nā enamel uea polyesterimide solderable ma nā uea magnet no nā relays, nā mea hoʻololi liʻiliʻi, nā motika liʻiliʻi, nā mea hoʻopili, nā coil hoʻā ahi, nā coil magnetic a me nā coil kaʻa. He kūpono loa kēia mau uhi i nā motika uila liʻiliʻi e hoʻopili i nā wili i ka mea hōʻiliʻili. Loaʻa i nā uea magnet i uhi ʻia ka elasticity maikaʻi a me nā waiwai dielectric a me mechanical maikaʻi. Loaʻa iā ia nā waiwai kemika maikaʻi loa, ke kūpaʻa wela maikaʻi a me ke kūpaʻa i nā refrigerants.
Polyamide-imide
Hiki ke hoʻohana ʻia nā enamel uea polyamide-imide ma ke ʻano he ʻaʻahu pālua a hoʻokahi paha, akā hāʻawi nā koho ʻelua i nā waiwai mechanical maikaʻi loa, ke kūpaʻa kemika, ke kūpaʻa wela kiʻekiʻe, ka ikaika tensile kiʻekiʻe a me ke kūpaʻa luhi.
Polyimide
Ka helu mahana: 240C
Ua kūʻai ʻia ʻo PI e DuPont i nā makahiki 1960. ʻO ia ka uhi organik kiʻekiʻe loa o ka mahana. Hoʻopili ʻia ma ke ʻano o kahi hopena polyamic acid, i hoʻololi ʻia me ka wela i kahi kiʻiʻoniʻoni hoʻomau. Loaʻa iā ia ke kūpaʻa wela maikaʻi loa, kū i ka radiation, nā kemika a me nā mahana cryogenic. ʻOki ʻia ma lalo o 500℃.
ʻEnamel hoʻopili ponoʻī
Ma muli o nā pono hana like ʻole o ka mea kūʻai aku, he ʻano like ʻole kona a me kahi ākea o nā noi. Hoʻohana ʻo Tianjin Ruiyuan i nā enamels hoʻopaʻa ponoʻī i hoʻokumu ʻia ma ka epoxy, hoʻohana ʻia ka polyvinyl-butyral a me ka polyamide e hoʻopaʻa i ka wili. Hoʻohana nui ʻia lākou e uhi i nā wili mea kani, nā wili leo, nā mea hoʻolele leo, nā motika liʻiliʻi a me nā mea ʻike.
Hiki ke hana ʻia nā uea makeneka āpau e like me ke kauoha a nā koi o nā mea kūʻai aku, ʻo Tianjin Ruiyuan, kāu mea hoʻolako hoʻonā uea makeneka ʻoihana. E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou inā he mau nīnau kāu.
