Uburyo bwo Kuzamura Ibiranga PVC - Uruhare rwinyongera.

PVC resin yabonetse muri polymerisiyasi ntigihungabana cyane kubera ubushyuhe buke bwumuriro & viscosity nyinshi. Igomba guhinduka mbere yo gutunganya ibicuruzwa byarangiye. Imiterere yacyo irashobora kongererwa imbaraga / guhindurwa hiyongereyeho inyongeramusaruro nyinshi, nka stabilisateur yubushyuhe, UV stabilisateur, plasitike, impinduka, ingaruka, kuzuza, flame retardants, pigment, nibindi.

Guhitamo ibyo byongeweho kugirango uzamure polymer biterwa nibisabwa byanyuma. Urugero:

1.Plastiseri (Phthalates, Adipates, Trimellitate, nibindi) ikoreshwa nkibikoresho byoroshya kugirango byongere imikorere ya rheologiya ndetse nubukanishi (gukomera, imbaraga) byibicuruzwa bya vinyl mukuzamura ubushyuhe. Ibintu bigira ingaruka kumahitamo ya plasitike ya vinyl polymer ni: Guhuza polymer ； Umuvuduko muke ； igiciro.

2.PVC ifite ubushyuhe buke cyane bwumuriro kandi stabilisateur ifasha mukurinda kwangirika kwa polymer mugihe cyo gutunganya cyangwa guhura numucyo. Iyo ikozwe nubushyuhe, ibice bya vinyl bitangiza reaction yihuta ya dehydrochlorination kandi izo stabilisateur zitesha agaciro HCl yabyaye izamura ubuzima bwa polymer. Ibintu bigomba kwitabwaho muguhitamo stabilisateur yubushyuhe ni: ibisabwa bya tekiniki Appro Kwemeza amabwiriza ； igiciro.

3.Abuzuza bongerewe mubice bya PVC kubwimpamvu zitandukanye. Uyu munsi, uwuzuza arashobora kuba inyongera yimikorere mugutanga agaciro muburyo bushya kandi bushimishije ku giciro gito gishoboka. Bafasha kuri: kongera ubukana n'imbaraga, kunoza imikorere yingaruka, ongeraho ibara, ububobere nubushobozi nibindi.

Kalisiyumu karubone, dioxyde ya titanium, ibumba ryabazwe, ikirahure, talc nibindi ni ubwoko bwuzuza bukoreshwa muri PVC.

4.Amavuta yo hanze akoreshwa mugufasha kunyura neza ya PVC gushonga binyuze mubikoresho bitunganya. mugihe amavuta yimbere agabanya ubukonje bwashonze, irinde ubushyuhe bwinshi kandi urebe neza ibara ryibicuruzwa.

5.Ibindi byongeweho nkibikoresho byo gutunganya, abahindura ingaruka, byongeweho kugirango bitezimbere imashini kimwe nubuso bwa PVC.
