Mitundu Yaikulu ya Enamel Yophimbidwa ndi Waya Wamkuwa wa Ruiyuan Enamel!

Enamel ndi ma varnish opakidwa pamwamba pa waya wamkuwa kapena alumina ndipo amapangidwa kuti apange filimu yoteteza magetsi yokhala ndi mphamvu zina zamakaniko, yolimbana ndi kutentha komanso yolimbana ndi mankhwala. Izi zikuphatikizapo mitundu yodziwika bwino ya enamel ku Tianjin Ruiyuan.

Polyvinylformal
Utoto wa Polyvinylformal ndi umodzi mwa utoto wakale kwambiri wopangidwa, womwe unayamba mu 1940. Nthawi zambiri umatchedwa FORVAR (womwe kale unkapangidwa ndi kampani ya Monsanto ndipo tsopano umapangidwa ndi Chisso), ndi chinthu chopangidwa ndi formaldehyde ndi polyvinyl acetate yomwe imapangidwa ndi hydrolyzed. PVF ndi yofewa ndipo imakhala ndi kukana kofooka kwa solvent. Komabe, imatha kugwira ntchito bwino ikagwiritsidwa ntchito limodzi ndi phenolic resin, melamine formaldehyde resin kapena polyisocyanate resin.

Polyurethane
Polyurethane idapangidwa ku Germany kumapeto kwa zaka za m'ma 1940. Poyamba, kutentha kwake kunali pakati pa 105°C ndi 130°C, koma tsopano yasinthidwa kufika pa 180℃, ndipo yagwira ntchito bwino. Imagwiritsidwa ntchito kwambiri pazinthu zamagetsi zotsika mphamvu monga ma coil olondola, ma mota, zida, zida zapakhomo, ndi zina zotero chifukwa cha utoto wake wabwino kwambiri, kukhuthala kwake kwakukulu komanso kuthekera kwake kosokera molunjika.
Waya wa PU ukhoza kugulitsidwa popanda kuchotsa chophimbacho.

Polyamide
Komanso imatchedwa nayiloni, imagwiritsidwa ntchito kwambiri ngati topcoat ndipo imatha kusintha mafuta, mphamvu zakuthupi ndi zamakaniko za PVF, PU ndi PE enamel. Polyamide ingagwiritsidwe ntchito ngati mayankho a ulusi wosavuta kapena ma polima osweka. Zomwe zili mu molekyulu ya polima iyi zimathandiza kuti yankho likhale ndi kukhuthala kwakukulu pamlingo wochepa wa zinthu zolimba.

Polyester
Mphamvu yabwino ya makina, kukanikiza filimu ya utoto, mphamvu yabwino kwambiri yamagetsi, kukana mankhwala, kukhazikika kwa kutentha komanso kukana zosungunulira; imagwiritsidwa ntchito mu ma coil olumikizirana zamagetsi, ma mota otsekedwa pansi pamadzi, ma micro-generator, ma transformer okana kutentha, ma contactor, ndi valavu yamagetsi. Enamel yosavuta kwambiri ya polyester ndi zotsatira za terephthalic acid, glycerin ndi ethylene glycol yomwe ndi kapangidwe kake ka polyester enamel ya 155°C. (Ngakhale kuti kutentha kwa utoto uwu kumaposa 180, zinthu zina monga kutentha kumafika pa 155°C, pokhapokha ngati pamwamba pake pakutidwa ndi nayiloni).

Polyesterimide
Ma waya a polyesterimide osungunuka amagwiritsidwa ntchito kwambiri pa mawaya a maginito a ma relay, ma transformer ang'onoang'ono, ma mota ang'onoang'ono, ma contactor, ma ignition coil, maginito coil ndi ma automotive coil. Zophimba izi ndizoyenera kwambiri pama mota ang'onoang'ono amagetsi kuti alumikize ma windings ku collector. Ma waya a maginito ophimbidwa ali ndi kusinthasintha kwabwino komanso mphamvu zabwino za dielectric ndi makina. Ali ndi mphamvu zabwino kwambiri zamakemikolo, kukana kutentha bwino komanso kukana ma refrigerants.

Polyamide-imide
Ma enamel a waya a polyamide-imide angagwiritsidwe ntchito ngati ma coat awiri kapena amodzi, koma mitundu yonse iwiriyi imapereka mawonekedwe abwino kwambiri a makina, kukana mankhwala, kukana kutentha kwambiri, kulimba kwambiri komanso kukana kutopa.

Polyimide
Kuyeza kwa Kutentha: 240C
PI idagulitsidwa ndi DuPont m'zaka za m'ma 1960. Ndi chophimba chachilengedwe chapamwamba kwambiri chomwe chimagwiritsidwa ntchito kutentha kwambiri. Chimagwiritsidwa ntchito ngati yankho la polyamic acid, losinthidwa ndi kutentha kukhala filimu yopitilira. Lili ndi kukhazikika kwabwino kwa kutentha, lolimba ku radiation, mankhwala ndi kutentha kwa cryogenic. Chidebe chodulidwa ＞500℃.

Enamel yodzimamatira
Kutengera zosowa zosiyanasiyana za kasitomala, ili ndi makhalidwe osiyanasiyana komanso ntchito zosiyanasiyana. Tianjin Ruiyuan imagwiritsa ntchito ma enamel odzigwirizanitsa okha omwe amachokera ku epoxy, polyvinyl-butyral ndi polyamide amagwiritsidwa ntchito kukhazikika kwa kuzunguliza. Amagwiritsidwa ntchito kwambiri kuphimba ma coil a zida, ma coil amawu, ma loudspeaker, ma mota ang'onoang'ono ndi masensa.

Mawaya onse a maginito akhoza kupangidwa kuti agwirizane ndi zosowa za makasitomala, Tianjin Ruiyuan, katswiri wopereka mayankho a maginito a maginito. Chonde musazengereze kulankhula nafe ngati muli ndi mafunso.
