Tuubbada Polyvinyl chloride, oo sidoo kale sheeganaysa tuubada pvc, waa tuubada kuleyliyaha kuleylka sarreeya ee polymerization ee vinyl choride monomer la sameeyay, u qaado polyvinyl chloride (PVC) RESINS sida alaabta ceeriin ee ugu weyn, ku dar wakiilka gabowga ku habboon, wakiilka guryaha hagaajinaya. iwm., walxaha ku sameysmaya farsamooyinka sida isku dhafka, calending, vacuum formings.

U adkaysiga tuubada Pvc ee daxalka waa mid xoogan, waa isku xirnaanta si ay u sahlanaato, PVC waxay leedahay iska caabin aad u xoogan si ay u oksijiinta, wakiilka reductive iyo acid xoog leh.Laakiin waa la daxaloobay karaa iyo sidoo kale munaasab aan la dabaqi karin la xiriir la hydrocarbon udgoon, hydrocarbon chlorinated sida vitriol ah. saliid, nitric acid ay ku urursan tahay oksidizing acid.

Laakiin, tuubada pvc, gaar ahaan UPVC caabbinta kulaylku waa liidata, iyo xoogga xajinta deegaanka ayaa hoos u dhacaysa in ka badan 60 ℃, iyo jawiga heerkulka hooseeya, Vybak biyaha toogashada iska caabbinta shoogga waxay hoos u dhigtaa. Gaadiidka, rakibidda iyo habka isticmaalka, si fudud waxaa jira jajab. dillaac;Intaa waxaa dheer, waxqabadka tuubada pvc u adkeyso naxdinta sidoo kale waa liidata.
