Ntawm no yog txoj kev sib piv ntshiab ntawm PVC, CPVC, thiab UPVC, suav nrog lawv qhov sib txawv tseem ceeb thiab cov ntawv thov:
{{0 {}} pvc (polyvinyl chloride)
Cov Khoom Siv: Qauv Yas Tsis Muaj Chlorination .
Qhov kub txwv: Txog li 60℃(140℃f) .
Kev Ntsuas Siab: 150-300 PSI (txawv los ntawm cov sijhawm).
Cov khoom tseem ceeb:
Rigid thiab lub teeb yuag .
Pheej yig thiab yooj yim rau nruab .
Tsis haum rau dej kub .
Kev siv ntau yam:
✔ Cov Dej Txias
✔ Tso dej / khib nyiab / Ultrasonic (DWV)
✔ Qhov hluav taws xob conduit
{{0 {}} cpvc (cporinated polyvinyl chloride)
Cov khoom siv: pvc nrog cov tshuaj loj (ntau dua cov cua sov tiv taus) .
Qhov kub txwv: nce mus txog 93℃(200℃f) .
Kev Ntsuas Siab: 100-400 PSI (nyob ntawm cov sijhawm teem sijhawm).
Cov khoom tseem ceeb:
Noj cov dej kub thiab cov kua dej txhaws ua kom zoo nkauj .
Kev yoog tau ntau dua li PVC .
Yuav tsum muaj cov kuab tshuaj xis nyob tshwj xeeb (incompatone nrog PVC kua nplaum) .
Kev siv ntau yam:
✔ Cov Dej Txias Kub / Dej Txias
✔ Muaj kev thauj cov tshuaj thauj
✔ Hluav Taws Sprinkler system
{{0 {}}} upvc (unplasticized PVC)
Cov khoom siv: pvc tsis muaj cov yas qhwv (rigid thiab ruaj khov) .
Qhov kub txwv: Txog li 60℃(140℃f) .
Siab ntsuam xyuas: zoo ib yam li PVC tab sis ntau nkaws .
Cov khoom tseem ceeb:
Cov tshuaj tiv thaiv zoo rau cov tshuaj / huab cua .
Tsis ua warp lossis degrade nyob rau hauv lub hnub ci .
Siv nyob qhov twg leaching yog kev txhawj xeeb (tsis muaj cov tshuab yas) .
Kev siv ntau yam:
✔ Qhov rai / Rooj
✔ Sab nraum zoov cov kav dej
✔ Kev siv piping (acids / alkalis)
Thaum twg siv qhov twg?
Pvc: dej txias, tso dej, cov phiaj xwm qis .
CPVC: Cov Dej Kub, Cov Dej Cure, Hluav Taws Kub .
UPVC: Sab Nraum Zoov / Kev Siv Khoom Siv, Tsis Muaj-Ntsev Kev Siv.
Nco tseg:
Tsis txhob siv PVC lo rau cpvc (xav kom CPVC-qhia meej Maas) .
UPVC tsis yog rau cov dej kub kub (tsis zoo li CPVC) .
