PVC ni iki?
Imvange za PVC zishingiye ku ruvange rwa PVC polymer RESIN n'inyongera zitanga imvange ikenewe kugira ngo ikoreshwe burundu (Imiyoboro cyangwa Imvange Zihamye cyangwa Imvange Zihindagurika cyangwa Amashuka). Imvange ikorwa no kuvanga neza ibintu, hanyuma bigahinduka ikintu "gikozwemo gel" bitewe n'ubushyuhe n'imbaraga zo gukata. Bitewe n'ubwoko bwa PVC n'inyongera, imvange mbere yo gukaraba ishobora kuba ifu itemba (izwi nk'uruvange rwumye) cyangwa amazi mu buryo bwa paste cyangwa umuti. Imvange za PVC iyo zikozwe, hakoreshejwe plasticizers, mu bikoresho byoroshye, ubusanzwe byitwa PVC-P. Imvange za PVC iyo zikozwe nta plasticizer yo gukoreshwa mu buryo bukomeye zitwa PVC-U. Imvange za PVC zishobora kuvugwa muri make ku buryo bukurikira: Imvange za PVC zihamye... -
