Budada cinjirka polymer dib loo cusboonaysiin karoAlaabooyinku waa budo dib loo cusboonaysiin karo oo biyo-milmi kara, kuwaas oo loo qaybiyay ethylene/vinyl acetate copolymers, vinyl acetate/tertiary ethylene carbonate copolymers, acrylic acid copolymers, iwm, oo leh alkolada polyvinyl sida kolloid ilaalin ah.Sababo la xiriira awoodda xidhitaanka sare iyo sifooyinka gaarka ah ee budada polymer ee la kala firdhiyo
Ku darida budada polymer-ka ee kala firdhisan ee hoobiye-buuxinta wadajirka ah waxay hagaajin kartaa isku-duubnideeda iyo dabacsanaanteeda.
Hoobiyaha isku-xidhka ah waa inuu lahaadaa ku-dhejin wanaagsan oo ku xiran walxaha saldhigga ah si loo xiro xitaa haddii si khafiif ah loo mariyo.Hoobiyeyaasha sibidhka ee aan la beddelin guud ahaan si fiican uma xidhna iyada oo aan la sii daawayn saldhigga.
Ku darida budada cinjirka ee dib loo kala firdhi karo waxay hagaajin kartaa xabagta.Iska caabbinta saponification ee budada cinjirka ee dib loo cusboonaysiin karo waxay xakameyn kartaa heerka ku dhegganaanta hoobiye ka dib marka la taabto biyaha iyo dhaxan.Polymer-ka u adkaysta saponification-ka waxaa lagu heli karaa iyada oo la koobiyeeyo vinyl acetate iyo monomers kale oo ku habboon..Isticmaalka ethylene sida comonomer non-saponifiable si loo soo saaro ethylene-ka kooban budada cinjirka dib loo firdhi karo waxay buuxin kartaa dhammaan shuruudaha budada cinjirka ah marka la eego iska caabinta gabowga iyo caabbinta hydrolysis.
