Menene Cikakken Siffar Bututun PVC?

PVC yana nufin Polyvinyl chloride. Bututun PVC kawai yana nufin bututu da aka yi daga wannan abu - polymer na roba thermoplastic wanda aka samar ta hanyar polymerizing vinyl chloride monomer (VCM).

Ana iya tsara PVC a matsayin m ko sassauƙa. Ana amfani da PVC mai ƙarfi don bututu, kayan aiki, da bawuloli saboda yana riƙe da siffarsa da ƙimar matsin lamba a ƙarƙashin kaya; PVC mai sassauƙa , wanda ya ƙunshi masu amfani da filastik, yana shiga cikin samfuran kamar rufin kebul da hoses. Don bututun, kusan koyaushe shine tsayayyen tsari - don haka 'PVC pipe' ba kalmar sinadari ce daban ba, bututu ne kawai da aka gina daga fili na PVC.

UPVC vs CPVC

A mafi yawan kasuwanni, ''PVC bututu'' tuni yana nufin ƙaƙƙarfan nau'in uPVC da ake amfani da shi don matsa lamba da tsarin magudanar ruwa. CPVC keɓantaccen abu ne mai chlorinated wanda aka zaɓa lokacin da ruwan ya yi zafi fiye da daidaitaccen PVC zai iya ɗauka.
