Thaum xaiv cov ntaub ntawv rau cov kav dej, dej, lossis kev siv tshuab, koj tuaj yeem pom ob qho kev xaiv zoo sib xws: PVC (polyvinyl chloride) thiab Cpvc yeeb nkab fittings(Chlorinated polyvinyl chloride). Thaum lawv qhia qee yam zoo sib xws, lawv muaj qhov txawv nyob rau hauv lawv cov khoom, kev siv, thiab muaj peev xwm ua tau zoo. Nkag siab cov kev sib txawv no yog qhov tseem ceeb kom ua tiav qhov ua tiav thiab kev nyab xeeb ntawm koj qhov project.
Dab tsi yog PVC thiab CPVC?
PVC yog dav siv cov khoom siv yas ntim rau nws cov kav ntev, muaj nqis, thiab versatility. Nws tau dhau los ua ib qho staple hauv kev tsim kho thiab kav dej, feem ntau rau cov kev siv uas suav nrog cov dej txias lossis cov khoom siv txias. CPVC, ntawm qhov tod tes, yog daim ntawv hloov kho ntawm PVC uas tau nkag mus rau cov txheej txheem chlorination ntxiv. Tus txheej txheem no nce CPVC cov chlorine cov ntsiab lus, txhim kho nws cov cua sov thiab tshuaj lom neeg kuj.
Txawm hais tias lawv yog ob qho tib si muab tau los ntawm tib lub polymer, qhov sib txawv ntawm lawv cov khoom ua rau muaj kev sib txawv ntawm kev ua tau zoo thiab ua haujlwm.
Qhov sib txawv ntawm PVC thiab Cpvc fittings
1. Kub tsis kam
Ib qho ntawm qhov tseem ceeb tshaj plaws ntawm PVC thiab CPVC yog lawv lub peev xwm tiv taus cov cua sov.
- PVC fittings:PVC yog qhov tsim nyog rau lub tshuab uas qhov kub tshaj plaws tsis tshaj 140 ° F (60 ° C). Nws yog qhov zoo tagnrho rau cov dej txias, dej sab nraud, thiab cov ntawv thov tso dej. Txawm li cas los xij, raug rau qhov kub siab dua tuaj yeem ua rau cov khoom siv tsis muaj zog, ua rau kev ua rog lossis txi.
- Cpvc fittings:CPVC muaj peev xwm lis kub npaum li xyoo 200 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° F (93 ° Qhov kev tiv thaiv tshav kub no yog los ntawm nws cov chlorination ntxiv, uas ntxiv dag zog rau cov qauv polymer.
2. Tshuaj Zoo
Lwm qhov tseem ceeb yog li cas cov ntaub ntawv teb rau ntau yam tshuaj.
- PVC fittings:Thaum pvc yog tiv taus ntau yam tshuaj, nws tsis yog tsim nyog rau cov acidic siab lossis kev xeb ib puag ncig. Ntev tau raug rau qee cov tshuaj muaj peev xwm tuaj yeem txwv nws cov qauv sijhawm dhau sijhawm.
- Cpvc fittings:CPVC muaj cov tshuaj lom neeg zoo tshaj plaws, suav nrog kev tiv thaiv kom muaj zog acids, hauv paus, thiab ntsev. Qhov no ua rau nws xaiv tau zoo rau kev lag luam xws li kev thauj khoom siv tshuaj lom neeg thiab cov tshuab wastewater.
3. Lub cev thiab cim
Visually, PVC thiab CPVC tuaj yeem sib txawv los ntawm lawv cov xim:
- Pvc Fittingsfeem ntau yog xim dawb lossis txho.
- Cpvc fittingsfeem ntau ziab, beige, lossis daj.
Tsis tas li ntawd, CPVC fittings feem ntau tuaj nrog cov cim tshwj xeeb uas qhia lawv qhov ntsuas kub thiab ntsuas kub. Cov cim no pab xyuas kom paub tseeb tias cov ntaub ntawv siv tau raug nyob hauv cov ntawv thov uas tsim nyog.
4. Nqi thiab muaj
- PVC fittings:Vim tias PVC yuav tsum muaj cov kauj ruam ua tsawg dua, nws yog feem ntau muaj nqis pheej yig thiab dav muaj.
- Cpvc fittings:CPVC yog kim dua vim muaj cov txheej txheem chlorination ntxiv thiab txhim kho kev ua tau zoo. Txawm li cas los xij, nws tus nqi siab dua yog kev ncaj ncees rau hauv cov ntawv thov uas kub thiab tshuaj lom neeg kuj tseem ceeb.
5. Daim ntawv pov thawj thiab cov ntawv thov
Ob cov ntaub ntawv muaj cov ntawv pov thawj tshwj xeeb thiab cov qauv siv rau kev siv. Txawm li cas los xij, CPVC fittings feem ntau yog muaj ntawv pov thawj rau kev siv hauv cov ntawv teev tshwj xeeb xws li cov dej sprinkler lossis dej kub.
- PVC yog qhov zoo tagnrho rau:
- Dej Txias Dej
- Irrigation Tshuab
- Lub Nruab qis-siab tau dej khov
- Cpvc yog qhov zoo tagnrho rau:
- Cov kav dej kub
- Hluav Taws Hluav Taws Kub
- Kev lag luam piping nrog tshuaj lom neeg raug
Puas yog lawv hloov pauv tau?
Txawm hais tias PVC thiab CPVC yuav zoo sib xws, lawv tsis tau hloov kho tau vim lawv cov khoom sib txawv. Piv txwv li, siv pvc nyob rau hauv qhov kev kub-ib puag ncig yuav ua rau cov khoom tsis ua haujlwm thiab muaj peev xwm kev nyab xeeb kev nyab xeeb. Ib yam li ntawd, siv CPVC hauv ib qho xwm txheej uas nws cov nqi txhim kho tsis tau yuav ua rau tsis muaj nqis.
Tsis tas li ntawd, cov nplaum siv rau koom nrog PVC thiab CPVC yog txawv. Cov kuab tshuaj nyob rau hauv PVC Maas yuav tsis tsim kev sib tsoo nrog CPVC cov ntaub ntawv, thiab hloov ua lwm yam. Nco ntsoov xyuas kom koj siv cov cement yog thiab primer rau cov khoom siv tshwj xeeb.
