Ibicuruzwa bya PVC bifata ibicuruzwa byera, ariko rimwe na rimwe bihinduka umuhondo iyo bibitswe igihe kirekire. Impamvu ni iyihe?

Ubwa mbere, ugomba kumenya niba hari ikibazo hamwe numukozi watoranijwe. PVC ifasha kugenzura ifuro ikoresha ifuro kugirango ibore kandi itange gaze itera imyenge. Iyo ubushyuhe bwo gutunganya bushobora kugera ku bushyuhe bwangirika bwumubyimba, ntibisanzwe. Ubwoko butandukanye bwibibyimba bifite ubushyuhe butandukanye bwo kubora, kabone niyo ubwoko bumwe bwibintu byinshi bibyara bikozwe nababikora batandukanye, ubushyuhe bwangirika ntibushobora kuba bumwe. Hitamo PVC ifasha kugenzura ibereye. Ntabwo PVC yose ibereye kubira ifuro, birakenewe rero guhitamo ibikoresho bifite impamyabumenyi ya polymerisiyasi nkeya. Ibikoresho nkibi bifite ubushyuhe buke bwo gutunganya, nka S700. Niba ushaka gukoresha 1000 na 700, birashobora kuba bitandukanye. Umukozi wifuro ashobora kuba yarangije kubora kandi PVC itarashonga.

Mubyongeyeho, hari izindi nyongera. Ubushyuhe bwo kubora bwibintu bisanzwe bibyimba birenze ubushyuhe bwo gutunganya PVC. Niba inyongeramusaruro ikwiye itongeyeho, igisubizo nuko PVC ibora (ihinduka umuhondo cyangwa umukara) kandi ACR itarabora (ifuro). Niyo mpamvu, birakenewe kongeramo stabilisateur kugirango PVC itajegajega (ntabwo ibora kubushyuhe bwa AC). Kurundi ruhande, inyongeramusaruro ziteza AC ifuro zongerwaho kugirango zigabanye ubushyuhe bwangirika bwa AC kandi bihuze. Hariho kandi inyongeramusaruro zo gukora imyenge ya ifuro ntoya kandi yuzuye, aribyo kwirinda guhora kwinini kwinshi no kugabanya imbaraga zibicuruzwa. Kubera ko ubushyuhe buri hasi kandi butagihinduka umuhondo, ndashobora kwemeza ko ubushyuhe bwawe bwambere bwatumye PVC ibora ihinduka umuhondo. Kwangirika kwa PVC ni kwiteza imbere kwifata, bivuze ko ibintu byangirika biteza imbere kubora. Kubwibyo, bikunze kugaragara ko ari byiza niba ubushyuhe butari hejuru, ariko niba ubushyuhe buri hejuru, bizangirika kubwinshi.
