Waa maxay dahaarka budada akrilik
looxa budada daahan waxay leeyihiin sifooyin qurxin heer sare ah, iska caabin cimilada, iyo iska caabinta wasakhowga, waxayna leeyihiin qallafsanaan sare oo dusha sare ah. Dabacsanaan wanaagsan. Laakiin qiimuhu waa sarreeyaa, iska caabbinta daxalka ayaa liidata. Sidaa darteed, dalalka Yurub generalisticmaal budada polyester-ka saafiga ah (resin ka kooban karboxiyl, oo lagu daaweeyay TGIC); (Hydroksyl-ka kooban xabagta polyester-ka ayaa lagu daaweeyaa isocyanate) sida daahan budo ah oo cimilada u adkaysata.
Curiska
Dahaarka budada akrilku waxay ka kooban yihiin resins acrylic, pigments iyo buuxinyeyaal, wax lagu daro iyo wakiilada daaweynta.
Noocyada
Sababtoo ah kooxaha kala duwan ee shaqeynaya ee ku jira qaabka molecular, resins acrylic waxay leeyihiin noocyada soo socda:
1. Resin Acrylic oo ay ku jiraan glycidyl ether functional group.
2. Xabagta acrylic oo ay ku jiraan kooxda shaqaynaysa karboksyl.
3. Resin Acrylic oo ay ku jiraan koox hawleed hydroxyl.
Xaaladaha Daawaynta
Sababo la xiriira qaab-dhismeedka kala duwan iyo kooxaha shaqeeya ee ku jira resins acrylic, wakiilada daaweynta ee la doortay iyo hababka daaweynta ayaa sidoo kale ka duwan. Ka dib marka la isku xiro, sifooyinka jireed iyo kiimikaad sidoo kale way kala duwan yihiin.
Xaaladaha daawaynta ee daaha budada akril waa:
Heerkulka heerkulka: 180 ℃ ~ 200 ℃;
Waqtiga daaweynta: 15min ~ 20min;
Hababka codsiga ee dahaarka budada heerkulbeegga waxaa loo isticmaali karaa daahan budada akril.
Hab-soo-saarka
Waxaa jira afar hab oo wax soo saar ah oo loogu talagalay daahan budada akril:
Mid waa habka uumiga.
Midda labaad waa habka qalajinta buufinta.
Midda saddexaad waa habka qoyan.
Ugu dambeyntii, waxay la mid tahay habka wax soo saarka ee daahan budada epoxy.
Habka wax-soo-saarka afraad ayaa inta badan la isticmaalaa.
Nidaamku waa sida soo socota:
Isku qas → extrusion → burburin → shaandhayn → baakad
