Isikhumba Sokwenziwa

Ukuvikela Ukukhiqizwa Kwesikhumba Okwenziwa Ngayo Nge-PVC Stabilizers

Kunezinqubo ezihlukahlukene zokukhiqiza zesikhumba sokwenziwa, phakathi kwazo okuwumgogodla, ukuhlanganisa ikhalenda, nokukhipha amagwebu.

Ezinqubweni zokushisa okuphezulu (180-220 ℃), i-PVC ijwayele ukuwohloka. Izinza ze-PVC ziphikisana nalokhu ngokumunca i-hydrogen chloride eyingozi, iqinisekisa ukuthi isikhumba sokwenziwa sigcina ukubukeka okufanayo kanye nesakhiwo esizinzile kukho konke ukukhiqizwa.

Ukuthuthukisa Ukuqina Kwesikhumba Okwenziwa Ngezinzinzisi ze-PVC

Isikhumba sokwenziwa siguga ngokuhamba kwesikhathi—siyabuna, siqina, noma siqhekeke—ngenxa yokukhanya, umoya-mpilo kanye nokushintsha kwezinga lokushisa. Iziqinisi ze-PVC zinciphisa ukuwohloka okunjalo, zelule isikhathi sokuphila kwesikhumba sokwenziwa; isibonelo, bagcina ifenisha nengaphakathi lemoto isikhumba sokwenziwa siphila futhi siguquguquka ngaphansi kokukhanya kwelanga okude.

Ukuhlanganisa Ukucutshungulwa Kwesikhumba Okwenziwa Ngezinzinzisi ze-PVC

I-Liquid Ba Zn Stabilizers: Iletha ukugcinwa kombala okuhle kakhulu kokuqala kanye nokumelana ne-sulfurization, ithuthukisa ikhwalithi yesikhumba sokwenziwa.

I-Liquid Ca Zn Stabilizers: Inikeza izakhiwo ezilungele imvelo, ezingenabo ubuthi ezinokuhlakazeka okuphezulu, ukumelana nesimo sezulu, nemiphumela yokulwa nokuguga.

I-Powdered Ca Zn Stabilizers: Ihambisana nemvelo futhi ayinabo ubuthi, iphromotha amabhamuza amahle afanayo esikhumbeni sokwenziwa ukuze kugwenywe izici ezifana namabhamuza amakhulu, aphukile, noma anganele.
