Waa maxay xuubka 'pva polyvinyl'

Proyvinylyl Fibroga Fiber ayaa inta badan loo isticmaalaa isku darka suufka, oo lagu dhejiyo dhar noocyo kala duwan oo suuf ah. Intaas waxaa sii dheer, waxaa sidoo kale lagu dhex gelin karaa fiilooyin kale ama isbadal saafi ah, oo dhaarta dhammaan noocyada la jeexjeexay ama dharka jilicsan. Waxqabadka iyo muuqaalka aalkolada polyvinyl waxay aad ula mid tahay tan silkworms dabiiciga ah, waxaana loo isticmaali karaa in lagu qurxiyo dharka satin. Si kastaba ha noqotee, sababtoo ah dabacsanaanteeda liita, ma fududa in dheeh, sidaa darteed laguma sameyn karo dhar heer sare ah. Sanadihii la soo dhaafay, horumarinta tikniyoolajiyadda wax soo saarka ee applyvinyl, codsigiisa warshadaha, beeraha, kalluumeysiga, gaadiidka, gaadiidka iyo si ay u sii ballaaranayaan.

Xanuunka 'polyvinyl' oo leh kororka heerka polympimemization, fiber hydrophobicity ayaa kordha, heerkulka culeyska biyaha ee biyaha ayaa kor u kaca si ku habboon. Sidaa darteed, adeegsiga shahaadada polymerization ee hoose ee aalkolada polyvinyl ee loogu talagalay isqarxinta, waxay heli kartaa heerkulka hoose ee biyaha ee milatariga ah ee fiberka. Si kastaba ha noqotee, shahaadada polymarization-ka ayaa hoos udhaca, is-kala-sooca ayaa ka sii daraya. Patent Japan waxay adeegsadaan shahaadada polymerization (wax ka yar 800) qaybo iyo shahaado badan oo polymerization ah (in kabadan 1000) qaybood oo isku-dhafka ah, fiber-ka is-dhejinta, cufnaanta biyaha ayaa ku habboon.
