Enamels waa varnishes lagu dahaadhay dusha sare ee fiilooyinka naxaasta ama alumina waxaana la qalajiyey si ay u sameeyaan filim dahaadh koronto oo leh awood farsamo gaar ah, sifooyin u adkaysta kulaylka iyo kiimikooyinka. Kuwa soo socda waxaa ka mid ah noocyada dhaldhalaalka ee caadiga ah ee Tianjin Ruiyuan.
Polyvinylformal
Resin-ka Polyvinylformal waa mid ka mid ah rinjiyada ugu da'da weyn ee macmal ah, oo dib ugu soo laabanaya 1940. Badanaa waxaa loo yaqaan FORVAR (oo hore u soo saartay shirkadda Monsanto haddana ay soo saarto Chisso), waa badeeco polycondensation ah oo ka samaysan formaldehyde iyo polyvinyl acetate oo la hago. PVF waa mid jilicsan oo leh iska caabin liita oo dareere ah. Si kastaba ha ahaatee, waxay gaari kartaa waxqabad wanaagsan marka lala isticmaalo resin-ka phenolic, resin-ka melamine formaldehyde ama resin-ka polyisocyanate.
Polyurethane
Polyurethane waxaa lagu sameeyay Jarmalka dabayaaqadii 1940-meeyadii. Markii hore, heerka kulaylku wuxuu u dhexeeyay 105°C iyo 130°C, laakiin hadda waxaa loo hagaajiyay 180℃, iyo waxqabad wanaagsan. Waxaa si weyn loogu isticmaalaa alaabada korontada ee danab yar sida gariiradaha saxda ah, matoorrada, qalabka, qalabka guryaha, iwm. sababtoo ah midabaynteeda aadka u fiican, heerka dahaarka sare iyo si toos ah u alxanka.
Fiilada PU waa la alxami karaa iyada oo aan la xoqin dahaarka.
Polyamide
Sidoo kale waxaa loogu yeeraa nayloon, waxaa badanaa loo isticmaalaa dahaarka sare waxayna hagaajin kartaa saliidaynta, sifooyinka jireed iyo farsamo ee PVF, PU iyo dhaldhalaalka PE. Polyamide waxaa loo isticmaali karaa xalal ka mid ah faybar fudud ama polymers jajaban. Waxyaabaha adag ee molecular-ka ee polymer-kan waxay u oggolaaneysaa xalka inuu yeesho viscosity sare oo ku jira adkaha hoose.
Polyester
Awood farsamo oo wanaagsan, isku dhejinta filimka rinjiga, koronto aad u fiican, iska caabin kiimiko, xasillooni kuleyl iyo iska caabin dareere; waxaa loo isticmaalaa gariiradaha iftiinka isgaarsiinta elektaroonigga ah, matoorada biyaha hoostooda lagu shubo ee shaabadaysan, matoorrada yaryar, transformers-ka iska caabbinta kulaylka, contactors-ka, waalka elektromagnetic-ka. Dhalaaladda polyester-ka ugu fudud waa wax soo saarka falcelinta ee terephthalic acid, glycerin iyo ethylene glycol kaas oo ah halabuurka caadiga ah ee dhalaal polyester ah oo heerkiisu yahay 155°C. (In kasta oo cimriga kulaylka ee rinjiyadani uu ka badan yahay 180, sifooyinka kale sida shoogga kulaylka ayaa u dhow 155°C, haddii aan dusha sare lagu dahaadhin nayloon).
Polyesterimide
Enamel-yada siligga polyesterimide ee la milmi karo ayaa si weyn loogu isticmaalaa fiilooyinka birlabta ee loogu talagalay gudbinta, transformers-yada yaryar, matoorada yaryar, contactors-ka, gariiradaha dab-damiska, gariiradaha birlabta iyo gariiradaha baabuurta. Dahaarkan ayaa si gaar ah ugu habboon matoorada korontada yar yar si ay ugu xiraan wareegyada iyo ururiyaha. Fiilooyinka birlabta ee dahaarka leh waxay leeyihiin dabacsanaan wanaagsan iyo sidoo kale sifooyin dielectric iyo farsamo oo wanaagsan. Waxay leedahay sifooyin kiimiko oo aad u fiican, iska caabin kulayl wanaagsan iyo iska caabin qaboojiyaha.
Polyamide-imide
Enamel-ka siligga Polyamide-imide waxaa loo isticmaali karaa laba lakab ama hal lakab, laakiin labada ikhtiyaarba waxay bixiyaan sifooyin farsamo oo aad u fiican, iska caabin kiimiko, iska caabin kuleyl oo sare, xoog jiidis sare iyo iska caabin daal.
Polyimide
Qiimaynta Heerkulka: 240C
PI waxaa ganacsi ahaan u samaysay DuPont 1960-meeyadii. Waa dahaarka dabiiciga ah ee ugu sarreeya heerkulka. Waxaa lagu dabaqay qaab xal polyamic acid ah, oo lagu beddelay kulayl filim joogto ah. Waxay leedahay xasillooni kuleyl oo aad u fiican, oo u adkaysata shucaaca, kiimikooyinka iyo heerkulka cryogenic. Gooyo ＞500℃.
Dhalaal is-dhejin ah
Iyadoo ku xiran baahiyaha kala duwan ee wax soo saarka ee macaamiisha, waxay leedahay astaamo kala duwan iyo codsiyo kala duwan. Tianjin Ruiyuan waxay isticmaashaa dhaldhalaal isku xidha oo ku salaysan epoxy, polyvinyl-butyral iyo polyamide ayaa loo isticmaalaa in lagu xasiliyo wareegga. Waxaa inta badan loo isticmaalaa in lagu dahaadho gariiradaha qalabka, gariiradaha codka, sameecadaha, matoorada yaryar iyo dareemayaasha.
Dhammaan fiilooyinka magnet-ka waxaa loo samayn karaa si waafaqsan shuruudaha macaamiisha, Tianjin Ruiyuan, oo ah bixiyahaaga xalalka fiilooyinka magnet-ka ee xirfadleyda ah. Fadlan xor u noqo inaad nala soo xiriirto haddii aad wax su'aalo ah qabtid.
