Izinto ezijwayelekile zepulasitiki:
Ipulasitiki evame ukusetshenziswa akuyona ingxenye eyodwa, yakhiwe ngezinto eziningi.Phakathi kwazo, ama-polymers amangqamuzana aphezulu (noma ama-synthetic resins) ayizingxenye eziyinhloko zamapulasitiki.Ngaphezu kwalokho, ukuze kuthuthukiswe ukusebenza kwamapulasitiki, izinto ezihlukahlukene ezisizayo, ezifana nama-filler, ama-plasticizers, ama-lubricant, nama-stabilizers, kufanele zengezwe kumakhompiyutha aphezulu., Ama-Colourants, ama-antistatic agents, njll., angaba amapulasitiki ngokusebenza kahle.
Izithasiselo zepulasitiki, ezaziwa nangokuthi izithasiselo zepulasitiki, ziyizinhlanganisela okufanele zengezwe ukuze kuthuthukiswe ukusebenza kwe-polymer (i-synthetic resin) noma ukuthuthukisa ukusebenza kwe-resin ngokwayo lapho i-polymer (i-synthetic resin) icutshungulwa.Isibonelo, ukuze kuncishiswe izinga lokushisa lokubumba le-polyvinyl chloride resin, i-plasticizer yengezwa ukwenza umkhiqizo uthambile;esinye isibonelo siwukwengeza i-ejenti ekhihliza amagwebu ukuze kulungiswe igwebu elingasindi, elingadlidlizi, elivikela ukushisa, kanye negwebu elivikela umsindo;Izinga lokushisa lokubola liseduze kakhulu nezinga lokushisa lokucubungula ukubumba, futhi ukubumba akukwazi ukufezwa ngaphandle kokwengeza iziqinisi zokushisa.Ngakho-ke, izithasiselo zepulasitiki zithatha isikhundla esibaluleke kakhulu ekusetshenzisweni kokubumba kwepulasitiki.
Amapulasitiki amakhompiyutha e-polymer (ama-macromolecules), avame ukubizwa ngokuthi amapulasitiki noma ama-resin, enziwa i-polymerized ngama-monomers njengezinto zokusetshenziswa ngokuhlanganisa i-polymerization noma ukusabela kwe-polycondensation.Ukwakheka nokuma kungashintshwa ngokukhululekile.Yakhiwa ngama-synthetic resins nama-fillers.I-Plasticizer, i-stabilizer, i-lubricant, i-pigment nezinye izithasiselo.
