ni ubuhe bwoko bwa PVC?

Ibikoresho bya PVC bishingiye ku guhuza PVC polymer RESIN hamwe ninyongeramusaruro zitanga formulaire ikenewe kugirango imikoreshereze yanyuma (Imiyoboro cyangwa imyirondoro ya Rigid cyangwa imyirondoro yoroheje cyangwa impapuro).Uruvange rwakozwe no kuvanga cyane ibiyigize, bigahita bihinduka ingingo ya "gelled" bitewe nubushyuhe nimbaraga zogosha.Ukurikije ubwoko bwa PVC ninyongeramusaruro, ibivanze mbere yo gusohora birashobora kuba ifu itemba yubusa (izwi nkumuvange wumye) cyangwa amazi muburyo bwa paste cyangwa igisubizo.

Imvange ya PVC iyo yakozwe, ukoresheje plasitike, mubikoresho byoroshye, mubisanzwe bita PVC-P.

PVC Ifumbire iyo ikozwe idafite plastike ya porogaramu igoye yagenwe PVC-U.

PVC Guteranya bishobora kuvunagurwa muburyo bukurikira:

Ifu ya PVC yumye ivanze (yitwa Resin), nayo irimo ibindi bikoresho nka stabilisateur, inyongeramusaruro, ibyuzuza, imbaraga, hamwe na retardants, bigomba kuvangwa cyane mumashini ivanga.Kuvanga no gukwirakwiza kuvanga birakomeye, kandi byose bijyanye nubushyuhe bwasobanuwe neza.

Ukurikije formulaire, PVC resin, plasitike, Filler, stabilisateur nizindi mfashanyo zishyirwa mubivangavanze bishyushye.Nyuma yiminota 6-10 isohoka muri mixer ikonje (6-10 mins) kugirango ibanze.Imvange ya PVC igomba gukoresha imvange ikonje kugirango irinde ibintu bifatika nyuma yo kuvanga bishyushye.

Ibikoresho bivanze nyuma ya plastike, kuvanga no gutatanya neza hafi ya 155 ° C-165 ° C noneho bigaburirwa imvange ikonje.Gushonga PVC ivanze noneho irashishwa.Nyuma yo gusya, ubushyuhe bwa granules burashobora kugabanuka kuri 35 ° C-40 ° C.Noneho nyuma yo gukonjesha umuyaga ukonjesha umuyaga, ubushyuhe bwibice bugabanuka munsi yubushyuhe bwicyumba kugirango byoherezwe muri silo yanyuma yo gupakira.
