Dhallooyinka waa varnies-ka jaranjarada dusha sare ee naxaasta ah ama alumina fiilooyinka iyo in lagu daaweeyo si ay u sameeyaan filim farsamo-gal ah oo leh awood farsamo gaar ah, sifooyinka u adkaysta kuleylka iyo kiimikada u adkaysata. Waxyaabaha soo socdaa waxaa ka mid ah qaar ka mid ah noocyada caadiga ah ee dhaldhalaalka ah ee tianjin ruiyan.
Polyvinylffnal
Resin polyvinylfffformal-ka waa mid ka mid ah rinjiga ugu da'da weyn, oo lagu soo celiyo 1940. Waxaa soo saaray shirkadda Monsanto (oo ay soo saartay Chesson), waa wax soo saar polysconsing ah oo ka mid ah polyvinyl acetate. PVF waa mid aad u jilicsan oo leh iska caabin adag. Si kastaba ha noqotee, waxay ku gaari kartaa wax qabad ka fiican marka loo isticmaalo iyada oo lala kaashanayo phenolic resin phenolic, melamine forldehyde resin ama polyisocyanate Resin.
Polyurethane
Polyurethane waxaa lagu soo saaray Jarmalka dabayaaqadii 1940-yadii. Asal ahaan, heerka kuleylka wuxuu u dhexeeyey 105 ° C iyo 130 ° C, laakiin hadda waxaa loo hagaajiyay ilaa 180 ℃, iyo waxqabadka ka fiican. Waxaa si weyn loogu isticmaalaa alaabada korantada ee korantada ee hooseeya sida xirmooyinka saxda ah, matoorada, aaladaha guryaha, iwm.
PU silig waa la galin karaa iyada oo aan la xareyn daboolka.
Deked weyn
Sidoo kale magacyada sida NYLON, waxaa badanaa loo istcimaalaa sida topcoat-ka waxaana lagu hagaajin karaa saliidaha, guryaha jirka iyo farsamada ee PVF, PU iyo PE Enabel. Polyamide waxaa loo istcimaali karaa sidii xalka fiber fudud ama polym-ka jajab jajaban. Waxyaabaha adag ee Molocular of Polyper-kaan ayaa u oggolaanaya xalka inuu ku dhaco viscosity ka sarreeya oo ku jira nuxurka adkaha ah.
Codsato
Awoodda farsamada wanaagsan, rinjiga filimka adhesion, korantada korantada, kiimikada, xasilloonida kuleylka, xasilloonida kuleylka iyo caabbinta. Waxaa loo isticmaalaa in lagu isticmaalo isgaarsiinta elektiroonigga ah ee la shidmo xidhmooyin, matoor-gooyeyaal la soo xiray, matoorro-micro-micro-pontors, transforms-ka is-caabbicsi ee iska-caabbinta, ee la xidhiidha. Polyester ugu fudud ee 'polyester' waa wax soo saarka falcelinta ee asiidh, glycerin iyo ethellene glycol oo ah qaab caadi ah oo ah 155 ° C. (In kasta oo nolosha kululaynta rinjiyeyaashani ay ka badan tahay 180, guryaha kale sida shoogga kuleylka ayaa u dhow 155 ° C, haddii dusha sare laga saaro mooyee).
Polyesterimide
Dhalooyinka qumman ee polyeresterestimide-ka ee loo yaqaan 'polyerestemimerimide gire-ka' loo yaqaan 'polyesteremimeside' Xirmooyinkan ayaa si gaar ah ugu habboon si fiican ugu habboon matoorada korantada yar yar si ay ugu xiraan dabaysha u soo ururiyaha. Xaraashka Magnet-ka ee Magnet-ka waxay leeyihiin bartii wanaagsan iyo sidoo kale dielectric wanaagsan iyo sifooyinka farsamada. Waxay leedahay guryo kiimiko ah oo aad u fiican, iska caabin kuleyl wanaagsan iyo iska caabbinta qaboojiyaha.
Polyamide-Iide
Dhalidda fiilooyinka ee Polyamide-IMAMES waxaa loo isticmaali karaa laba-labo ama jaakad keliya, laakiin labada ikhtiyaarba waxay keenaan guryo farsamo oo heer sare ah, iska caabbinta kiimikada, iska caabin kulul, xoogga aadka u sarreeya iyo caabbinta.
Polbahide
Qiimaynta heerkulka: 240c
Pi wuxuu ka ganacsan jiray Dupont 1960-yadii. Waa dahabka heerkulka heerkulka ugu sareeya. Waxaa lagu dabaqay qaab xalka aashitada poranjic, loo beddelay kuleylka filim joogto ah. Haysashada xasilloonida kuleylka ee aad u fiican, u adkaysta shucaaca, kiimikooyinka iyo heerkulka dhawaaqa. Jar kaca> 500 ℃.
Is-adjoogsiga dhalmada
Waxay kuxirantahay baahiyaha wax soo saarka ee kala duwan ee macaamiisha, waxay leedahay astaamo kaladuwan iyo codsiyo fara badan. Tianjiin Ruiyan waxay isticmaashaa dhaldhalaalka is-isku-daridda ee ku saleysan Epoxy, polyvinyl-burral iyo polyamide waxaa loo isticmaalaa xasilinta dabaysha. Waxaa inta badan loo isticmaalaa in lagu jaro xirmooyinka aaladda, xirmooyinka codka, cod-bixiyeyaasha, motes yar yar iyo dareemayaasha.
Dhammaan fiilooyinka magnetka waxaa lagu dari karaa shuruudaha macaamiisha, tianjilin ruiyan, oo ah bixiyahaaga kharashka lagu iibiyo ee magnet-ka. Fadlan xor u tahay inaad nala soo xiriirto haddii aad wax su'aalo ah qabtid.
