I-PVC SG-8

incazelo emfushane:

I-thermoplastic high-molecular polymer eyenziwe yi-suspension polymerization ye-vinyl chloride monomer.I-molecular formula :- (CH2 – CHCl) n – (N: degree of polymerization, N= 590 ~ 1500).Yimpahla eluhlaza esetshenziswa kabanzi ekukhiqizeni ipulasitiki.Inokuqina okuhle kwamakhemikhali, ukumelana nokugqwala nokumelana namanzi.

Izinhlelo zokusebenza

I-Polyvinyl chloride resin inezinhlobonhlobo zezicelo, ezifana nezimoto zangaphakathi zezimoto, izinto zokuhlobisa zomndeni, ibhokisi lokukhanya lokukhangisa, izicathulo zezicathulo, amapayipi we-PVC nokufakwa, amaphrofayili we-PVC nepayipi, ishidi le-PVC nepuleti, ifilimu egoqayo, amathoyizi aphefumulayo, imikhiqizo yangaphandle, Intambo ye-PVC nekhebula, isikhumba sokwenziwa se-PVC, izinkuni nepulasitiki phansi, ibhodi likathayela, njll.
