Isikhwama sokupakisha sezingubo zePVC esicwebezelayo esikhanyayo

Isikhwama soziphu se-PVC empeleni siwuhlobo lwesikhwama sepulasitiki. Ingxenye eyinhloko yi-polyvinyl chloride, enombala okhanyayo, ukumelana nokugqwala futhi okuhlala isikhathi eside. Ngenxa yokwengezwa kwezinye izinto ezisizayo ezifana nama-plasticizers nama-anti-aging agents enqubweni yokukhiqiza ukuthuthukisa ukumelana nokushisa, ukuqina, i-ductility, njll., ingenye yezinto zokwenziwa ezithandwa kakhulu, ezithandwayo nezisetshenziswa kabanzi emhlabeni. .

Kunezindlela ezilula zokuhlukanisa izinzuzo nezingozi zezinto ze-PVC:

1. Iphunga: Lapho iphunga liba likhulu, libi kakhulu. Abanye abakhiqizi bafaka ngamabomu amakha ukuze bafihle iphunga elimnandi, ngakho isikhwama sepulasitiki esinephunga elinzima siyingozi emzimbeni, kungakhathaliseki ukuthi siphunga noma siphunga.

Ukuthinta okwesibili: Ukuba ngcono kwe-gloss ebusweni, kuhlanzeke izinto ezingavuthiwe kanye nekhwalithi ephezulu.

Izinyembezi ezintathu: Unyembezi lusho ukuqina. Izikhwama zimpofu uma zingadatshulwa zibe umugqa oqondile njengephepha. Isikhwama esihle sokupakisha sepulasitiki, noma ngabe ungqimba lwangaphandle luqhekekile phakathi nenqubo yokudabula, isendlalelo sangaphakathi sisaxhumekile.

Kukhona ezinye izimboni zezingubo zisebenzisa izikhwama zepulasitiki ezigaywe kabusha. Lezi zikhwama zepulasitiki zokugqoka ziyikhwalithi ephansi, futhi ama-reagents amakhemikhali ayengezwa ngesikhathi sokukhiqiza, okushiya ezinye izinto eziyingozi ezikhwameni. Ngokusho kwezici zalezi zinto, indinganiso yokwahlulela ikhwalithi yezikhwama zepulasitiki zokugqoka imane nje "iphunga elilodwa, ukubukeka okubili, nokudonsa okuthathu".Uma ifilimu yesikhwama sepulasitiki inokungcola elangeni noma ekukhanyeni, kufanele kube a isikhwama sezinto ezigaywe kabusha.
