YAS PVC COV YEEB NKAB FITTINGS

Cov khoom sib piv: PVC VS UPVV VS CPVC

Thaum xaiv cov ntaub ntawv piping rau cov chaw nyob, coj mus muag, nws yog qhov tseem ceeb kom nkag siab txog cov yam ntxwv ntawm PVC, UPVC, thiab CPVC. Txhua ntawm cov khoom siv no muaj qhov ua tau zoo, kev txwv, thiab cov ntawv thov zoo tagnrho. Cov ntawv no tshawb nrhiav lawv cov khoom, pab cov neeg siv tau qhia kev txiav txim siab raws li kev ua tau zoo, kev nyab xeeb, thiab kav ntev.

1. Cov ntsiab lus yooj yim thiab cov khoom siv tshuaj lom

PVC (polyvinyl chloride) yog ib qho ntau yam thermoplastic feem ntau siv nyob rau hauv kev tsim kho, tshwj xeeb tshaj yog nyob rau hauv tshuab thiab cua tshuab. UPVC (Unplasticized polyvinyl chloride) yog qhov sib txawv ntawm PVC uas tsis muaj cov tshuab yas, ua rau nws ntau dua. CPVC (chlorinated polyvinyl chloride) yog chemically hloov nrog cov chlorine ntxiv atom, txhim kho nws qhov kub tiv taus thiab tshuaj lom neeg ruaj khov. Cov kev sib txawv no hauv cov qauv ua rau muaj kev sib txawv ntawm - Winth World thov.

2. Qhov kub thiab qhov siab tsis kam

Cpvc sawv tawm thaum nws los tuav dej kub thiab siab -}} siab nruab. Nws tuaj yeem muaj kev nyab xeeb ua haujlwm ntawm 93 qib (200℃F), hos tus txheej txheem pvc yog feem ntau ntsuas rau qhov siab tshaj plaws ntawm 60℃(140℃f). UPVC, thaum zoo sib xws hauv siab ntaus nqi rau PVC, tsis pom zoo rau cov dej kub siv. Rau cov txheej txheem cua sov lossis kev muaj cov txheej txheem uas xav tau cov cua sov kev sim, CPVC yog qhov kev xaiv uas xav tau. Conversely, pvc thiab UPVC yog qhov zoo tagnrho rau cold- dej kav thiab dav dej tshuab.

3. Tshuaj lom neeg tiv thaiv thiab cov ntawv thov

Tag nrho peb cov khoom siv tsis kam rau ntau yam tshuaj, tab sis CPVC ua tau zoo dua hauv kev tswj cov dej thiab ntau dua. Nws feem ntau yog siv nyob rau hauv lub chaw soj nstuam, kev ua yeeb yam, thiab dej kub. UPVC's rigidity thiab tshuaj lom neeg ua kom haum rau lub qhov rais thav ntawv, cov dej khov kho tshuab, thiab cov khoom siv hluav taws xob. PVC yog feem ntau siv nyob rau hauv cov kav dej uas muaj cov kav dej, dej phwj tuaj, thiab lub teeb yuag. To taub nyob ib puag ncig uas cov khoom yuav raug ntsia yog qhov tseem ceeb rau kev ua tau ntev- sij hawm ua haujlwm.

4. Durability thiab ntev

UPVC yog paub rau nws cov teeb tsa kev tawm tsam thiab UV kuj, ua rau nws zoo tagnrho rau kev siv sab nraum zoov yam tsis muaj kev xav tau lossis txheej. CPVC, txawm hais tias me ntsis ntau dua li UPVC, muaj cov kev xav tau zoo heev nyob rau hauv kev kub siab. PVC, thaum lub sijhawm ruaj khov nyob rau hauv sab hauv tsev lossis faus cov ntawv thov, yog cov kev cuam tshuam ntau rau kev cuam tshuam los ntawm UV kis. Tej zaum yuav muaj kev saib xyuas tsis tu ncua lossis tiv thaiv tiv thaiv yuav tsum muaj rau kev nthuav tawm rau PVC lawm. Thaum muab ntsia kom zoo, tag nrho peb cov khoom tuaj yeem ua rau ntau xyoo caum.

5. Tus nqi thiab kev txiav txim siab

PVC yog tus nqi tshaj plaws -}}}}} kev txiav tawm, ua rau nws nrov, ua rau nws nrov thiab loj} cov phiaj xwm charnel. UPVC, yuav tsum kim me ntsis, yuav tsum tau tuav ncaj qha tab sis muaj kev ua tau zoo dua qub. CPVC, qhov nqi kim tshaj plaws ntawm peb, ua kom nws raug nqi nrog tshav kub ua hauj lwm zoo thiab kev ntseeg tau hauv kev xav tau. Thaum cov tswv yim teeb tsa zoo sib xws - siv cov kuab tshuaj tua hluav taws xob thiab cov khoom siv xaiv nrog cov txheej txheem kev xav tau ua haujlwm.

Tag

Xaiv ntawm PVC, UPVC, thiab CPVC, thiab CPVC yog nyob ntawm daim ntawv thov cov kev xav tau tshwj xeeb - kub, thiab pob nyiaj siv tshuaj lom neeg. PVC yog qhov zoo rau tus nqi -} ua tau zoo, txias- dej system. UPVC muaj kev txhim kho lub zog thiab kav ntev rau cov ntawv thov cov qauv. CPVC muab tshuaj lom neeg zoo dua rau cov chaw xav tau. Nkag siab cov kev sib txawv no ua kom muaj kev ua tau zoo, kev nyab xeeb, thiab tus nqi - effecticiency hauv kav dej thiab kev tsim kho.
