Enamels ivarnish dzakaputirwa pamusoro pewaya dzemhangura kana alumina uye dzakagadzirwa kuti dzigadzire firimu remagetsi rinodzivirira kupisa rine simba remakanika, rinodzivirira kupisa uye rinodzivirira makemikari. Izvi zvinosanganisira mamwe marudzi eenamel akajairika kuTianjin Ruiyuan.
Polyvinylformal
Polyvinylformal resin ndeimwe yependi dzekare dzekugadzira, dzakatanga muna 1940. Inowanzozivikanwa seFORVAR (yaimbogadzirwa nekambani yeMonsanto uye ikozvino inogadzirwa neChisso), chigadzirwa chepolycondensation cheformaldehyde nehydrolyzed polyvinyl acetate. PVF yakapfava uye haina simba rekudzivirira solvent. Zvisinei, inogona kuita basa rakanaka kana ikashandiswa pamwe chete nephenolic resin, melamine formaldehyde resin kana polyisocyanate resin.
Polyurethane
Polyurethane yakagadzirwa muGermany mukupera kwema1940. Pakutanga, mwero wekupisa waiva pakati pe105°C ne130°C, asi ikozvino yavandudzwa kusvika pa180℃, uye kushanda kwayo kuri nani. Inoshandiswa zvakanyanya muzvigadzirwa zvemagetsi zvine voltage shoma zvakaita sema coils akanyatsogadzirwa, mota, zvishandiso, midziyo yemumba, nezvimwewo nekuda kwekudhaya kwayo kwakanaka, kumhanya kwayo kwakanyanya uye kugona kwayo kuchinjika.
Waya yePU inogona kusungirirwa pasina kubvisa chifukidziro.
Polyamide
Inonziwo nylon, inowanzoshandiswa se topcoat uye inogona kuvandudza mafuta, hunhu hwePVF, PU nePE enamel. Polyamide inogona kushandiswa semhinduro dzefiber yakapfava kana fragment polymers. Zviri mukati me polymer iyi zvinoita kuti mhinduro ive ne viscosity yakakwira pane zviri mukati me solids yakaderera.
Polyester
Simba rakanaka remakanika, kunamira kwependi, simba remagetsi rakanaka, simba remakemikari, simba rekupisa uye simba rekudzivirira solvent; rinoshandiswa mumagetsi ekutaurirana, mota dzinonyudzwa mumvura dzakavharirwa, ma micro-generator, ma transformer anodzivirira kupisa, ma contactor, electromagnetic valve. Polyester enamel iri nyore ndiyo mhinduro ye terephthalic acid, glycerin uye ethylene glycol inova chinhu chakajairika che polyester enamel ye 155°C. (Kunyange zvazvo nguva yekupisa yemapendi aya ichipfuura 180, zvimwe zvinhu zvakaita sekupisa zvinosvika 155°C, kunze kwekunge pamusoro payo pakafukidzwa ne nylon).
Polyesterimide
Mawaya epolyesterimide anosanganiswa anoshandiswa zvakanyanya pawaya dzemagineti dzerelay, matransformer madiki, mamota madiki, macontactor, ma ignition coils, mamagnetic coils uye ma automotive coils. Ma coatings aya anonyanya kukodzera mumota diki dzemagetsi kubatanidza ma windings kune collector. Waya dzemagineti dzakaputirwa dzine elasticity yakanaka pamwe ne dielectric yakanaka uye mechanical properties. Ine chemical properties yakanaka, inodzivirira kupisa zvakanaka uye inodzivirira ma refrigerants.
Polyamide-imide
Maenamel ewaya epolyamide-imide anogona kushandiswa semachira maviri kana kuti rimwe chete, asi sarudzo dzese dziri mbiri dzinopa hunhu hwakanaka hwemakanika, kuramba makemikari, kuramba kupisa zvakanyanya, simba rekudhonza zvakanyanya uye kuramba kuneta.
Polyimide
Kuyera Tembiricha: 240C
PI yakatengeswa neDuPont muma1960. Ndiyo organic coating yepamusoro-soro yemhando yekupisa. Yakashandiswa se polyamic acid solution, yakashandurwa nekupisa kuita firimu rinogara richipisa. Ine kugadzikana kwakanaka kwekupisa, inodzivirira mwaranzi, makemikari uye tembiricha dzinopisa. Yakachekwa ＞500℃.
Enamel inonamira pachayo
Zvichienderana nezvinodiwa nemutengi zvakasiyana-siyana pakugadzira, ine hunhu hwakasiyana uye mashandisirwo akasiyana-siyana. Tianjin Ruiyuan inoshandisa enamel dzinozvibatanidza dzakavakirwa pa epoxy, polyvinyl-butyral uye polyamide zvinoshandiswa kudzikamisa kutenderera. Dzinonyanya kushandiswa kuputira macoil ezvishandiso, macoil ezwi, maspika, mamota madiki uye masensa.
Waya dzese dzemagineti dzinogona kugadzirwa kuti dziodharwe zvichienderana nezvinodiwa nevatengi, Tianjin Ruiyuan, nyanzvi yenyu inopa mhinduro dzemagineti. Ndapota inzwa wakasununguka kutibata kana muine mibvunzo.
