Khoom taw qhia:
PVC-U dejcevsiv polyvinyl chloride resin ua cov khoom siv tseem ceeb, ntxiv cov khoom tsim nyog, thiab yog tsim los ntawm extrusion ua. Nws yog ib qho ntawm cov khoom siv yeeb nkab nrog cov cuab yeej paub tab thiab tau siv dav hauv tsev thiab txawv teb chaws. Cov khoom muaj qhov zoo ntawm lub neej ntev, corrosion kuj, thiab lwm yam, uas yog unmatched los ntawm cam khwb cia hlau kav; nws yog sib dua hauv kev tsim kho, yooj yim rau kev tswj thiab nruab, thiab yooj yim rau kev txuas. Nws yog dav siv nyob rau hauv kev tsim kho vaj tse, chemical drainage, thiab rainwater drainage.

Nta:
Cov khoom muaj qhov zoo ntawm lub neej ntev tsis sib xws thiab corrosion kuj ntawm cam khwb cia hlau kav; nws yog sib dua hauv kev tsim kho, yooj yim rau kev tswj thiab nruab, thiab yooj yim rau kev txuas. Nws yog dav siv nyob rau hauv kev tsim kho vaj tse, chemical drainage, thiab rainwater drainage.
1. Lub hardness saum npoo thiab tensile lub zog ntawm cov yeeb nkab yog zoo heev, thiab kev nyab xeeb ntawm covcevyog siab.
2. Tus nqi qis, lub neej ua haujlwm ntev, lub neej ua haujlwm ib txwm muaj peev xwm ncav cuag ntau tshaj 50 xyoo, tsis tas yuav kho thiab kho.
3. Lub raj xa dej muaj kev tiv thaiv zoo heev rau inorganic acids, alkalis, thiab ntsev. Nws yog tsim rau kev lag luam dej phwj tawm thiab kev thauj mus los. Nws tsis xeb lossis nplai, yog li yuav tsis muaj corrosion thiab shrinkage hauv.
Nws tsis yooj yim rau kev thaiv, thiab cov phab ntsa sab nrauv yuav tsis muaj kuab paug vim yog xeb ntawm covcov kav dej, xyuas kom muaj kev zoo nkauj ntawm lub tsev.
4. Cov yeeb nkab txhuam coefficient me me, cov dej ntws yog du, tsis yooj yim rau kev thaiv, thiab kev saib xyuas haujlwm me me.
5. Cov khoom siv muaj cov pa oxygen siab thiab ua rau nws tus kheej tua.
6. Lub linear expansion coefficient ntawm lub raj xa dej yog me me, thiab qhov deformation cuam tshuam los ntawm qhov kub thiab txias yog me me. Cov thermal conductivity thiab elastic modulus yog me me, thiab kev tiv thaiv kev ua haujlwm khov kho zoo dua li cov kav hlau cam khwb cia hlau.
7. Cov kav dej thiab fittings txuas nrog cov kua nplaum, txoj kev tsim kho yog yooj yim, kev ua haujlwm yooj yim, thiab kev teeb tsa kev ua haujlwm siab.
8. Nws yog non-toxic, tsis muaj tshuaj lom lead ntsev thiab lwm yam tshuaj lom neeg, thiab tsis muaj teeb meem rau tib neeg lub cev.
