1. Cov khoom sib txawv
PVC xaim yog tsim los ntawm ib leeg lossis ntau cov xov tooj hluav taws xob, thiab qhov saum npoo yog qhwv los ntawm ib txheej ntawm insulator kom tiv thaiv kev sib cuag nrog lub cev conductive. Internal conductor muab faib ua tooj liab liab thiab tinned tooj liab raws li ib txwm qauv.
Roj hmab xaim, tseem hu ua roj hmab sheath hlau, yog ob-insulated hlau; txheej txheej txheej thiab rwb thaiv tsev yog ua los ntawm roj hmab, tus neeg xyuas pib yog tooj liab ntshiab, thiab txheej rwb thaiv tsev feem ntau yog chlorinated polyethylene (CPE).
2. Kev siv sib txawv
Cov roj hmab xaim yog tsim rau cov khoom siv hluav taws xob, cov khoom siv hauv tsev, cov cuab yeej hluav taws xob, kev tsim kho teeb pom kev zoo thiab sab hauv ntawm lub tshuab, thiab lwm yam, uas yuav tsum muaj qhov muag muag lossis cov chaw txawb nrog AC rated voltages ntawm 300V / 500V thiab 450 / 750V thiab hauv qab no, xws li hluav taws xob txuas xov hlau los yog thaiv.
PVC hlau yog tsuas yog siv rau sab hauv kev sib txuas ntawm cov khoom siv hluav taws xob thiab hluav taws xob.
3. Cov yam ntxwv sib txawv
Qhov saum npoo ntawm PVC kab yeeb nkab yog du, cov kua kuj yog me me, nws tsis scaled, thiab nws tsis haum rau kev yug me nyuam ntawm cov kab mob. Lub coefficient ntawm thermal expansion yog me me thiab tsis ntsws los yog deform.
Cov roj hmab xov muaj qee qhov kev tiv thaiv huab cua thiab qee cov roj ua haujlwm, tuaj yeem tiv taus ntau dua cov khoom siv sab nraud, yog mos, zoo elasticity, txias tsis kam, UV tsis kam, zoo elasticity, thiab siab zog.
