UPVC:
Lub teeb yuag: cov khoom siv UPVC muaj qhov sib npaug ntawm tsuas yog 1/10 ntawm cov hlau cam khwb cia, yooj yim thauj thiab nruab, thiab txo cov nqi; Cov tshuaj tiv thaiv zoo tshaj: UPVC muaj cov kua qaub thiab alkali zoo heev; non-conductive: UPVC cov khoom siv tsis tuaj yeem ua hluav taws xob, thiab nws tsis raug rau electrolysis lossis corrosion tam sim no, tsis tas yuav tsum muaj kev ua haujlwm thib ob. Tsis tuaj yeem hlawv, tsis txhawb kev sib txuas, tsis muaj kev txhawj xeeb txog kev tiv thaiv hluav taws; yooj yim installation, tsis tshua muaj nqi: txiav thiab kev sib txuas yog yooj yim, kev siv cov PVC kua nplaum kev sib txuas xyaum ua pov thawj kom ntseeg tau thiab nyab xeeb, yooj yim rau kev khiav lag luam, tsis muaj nqi; ruaj khov: huab cua zoo heev, thiab tsis tuaj yeem ua cov kab mob Corrosion los ntawm fungi; tsis tshua muaj kev tiv thaiv, siab txaus tus nqi: du sab hauv phab ntsa, tsis tshua muaj fluidity poob, thiab av tsis yooj yim rau kev ua raws li cov yeeb nkab phab ntsa, kev saib xyuas yog qhov yooj yim, thiab cov nqi kho mob tsawg.
