Uyini Umehluko Phakathi Kwe-PVC Ne-Cpvc​

Wake wazibuza ukuthi yini eyenza i-PVC ne-CPVC zihluke? Ukuqonda lezi zinto kubalulekile ezisetshenziswayo ezahlukahlukene.

Kulesi sihloko, sizohlola umehluko omkhulu phakathi kwe-PVC ne-CPVC, okuhlanganisa izakhiwo zazo kanye nokusetshenziswa kwazo. Uzofunda nangokusetshenziswa okuvamile kwezinto ze-PVC nokuthi ungakhetha nini uhlobo ngalunye.

 

Ukuqonda i-PVC kanye ne-CPVC

Kuyini i-PVC?

I-PVC , noma i-Polyvinyl Chloride, iyipulasitiki eguquguqukayo esetshenziswa kabanzi ezimbonini ezahlukahlukene. Yaziwa ngokuqina kwayo kanye nokumelana nezimo zemvelo. Nazi ezinye izici ezivamile ze-PVC:

● Ilula: Kulula ukuyiphatha nokuyithutha.

● Kusebenza kahle: Ngokuvamile kushibhile kunezinye izindlela eziningi.

● Ukumelana namakhemikhali: Imelana nama-acid nama-alkali, okwenza ifaneleke kumapayipi nasezintweni ezifakwayo.

Inqubo Yokukhiqiza ye-PVC

Ukukhiqizwa kwe-PVC kuhilela ukupholisa i-vinyl chloride monomer (VCM). Le nqubo ivame ukufaka:

1. Ukwenziwa kwe-polymerization: I-VCM iyashiswa futhi icindezelwe, okuholela ekwakhekeni kwe-resin ye-PVC.

2. Izithasiselo: Izithasiselo ezahlukahlukene, njengeziqinisi kanye nezipulasitiki, zixutshwa ukuze kuthuthukiswe ukusebenza.

3. Ukubumba Nokukhipha: I-resin ibe isibunjwa ibe yimikhiqizo ngokusebenzisa amasu okubumba noma okukhipha.

Kuyini i-CPVC?

I-CPVC imele i-Chlorinated Polyvinyl Chloride. Ifana ne-PVC kodwa idlule enkambisweni ye-chlorination. Lokhu kuguqulwa kunikeza i-CPVC izakhiwo ezihlukile, ikakhulukazi ekusetshenzisweni kwezinga lokushisa eliphezulu.

Umehluko Oyinhloko Kusuka Ku-PVC Ejwayelekile

Nakuba zombili izinto zifana ngandlela thile, umehluko omkhulu uhlanganisa:
