Dab tsi yog qhov txawv ntawm PVC, UPVC thiab CPVC khoom?
Puas yog UPVC / CPVC ob leeg PVC?
Yuav kom paub qhov txawv ntawm cov khoom siv no, peb yuav tsum xub paub seb lawv yog cov khoom siv dab tsi.
PVC
PVC yog polymerized los ntawm vinyl chloride monomer (VCM). Cov khoom siv PVC muaj cov yam ntxwv tsis muaj tshuaj lom, tiv thaiv kev laus thiab cov kua qaub thiab alkali tsis kam, yog li nws tsim nyog rau kev siv cov kav dej tshuaj.
PVC (PolyVinylChloride) feem ntau muaj 7 qib (SG1-SG7) raws li qhov nyuaj thiab kev ua haujlwm ntawm cov khoom, thiab qhov ceev yog li 1.4g / cm. Cov khoom lag luam hauv qab SG4 feem ntau yog cov khoom muag muag, thiab ntau cov yas yas yuav tsum tau ntxiv thaum molding. Lawv tsuas yog siv los ua cov tawv tawv, hlau thiab cable rwb thaiv tsev txheej, ntsaws ruaj ruaj, thiab lwm yam.
SG5 thiab saum toj no yog cov khoom siv tawv, feem ntau yog siv los ua ntau yam kav dej, xws li cov kav dej, hluav taws xob, xa ntawv thiab kev sib txuas lus thiab cov yeeb nkab fittings, ntau daim hlau, ntawv, profiles, thiab lwm yam.
PVC molding shrinkage tus nqi yog 0. siv General hom phiaj yas. Txawm li cas los xij, vim nws qhov ntsuas kub qis, qhov siab tshaj plaws yog nyob ib puag ncig 80 degree, uas cuam tshuam nws txoj kev loj hlob.
CPVC
CPVC yog cov khoom siv polymer hloov kho los ntawm chlorination ntawm polyvinyl chloride (PVC) dua. Tom qab PVC resin yog chlorinated, cov ntsiab lus chlorine yog nce los ntawm 56.7 feem pua rau 63-69 feem pua, uas ua rau kom cov tshuaj ruaj khov thiab txhim kho cov khoom. Lub tshav kub tsis kam, acid, alkali, ntsev, oxidant thiab lwm yam corrosion.
UPVC
Kev sib xyaw ua ke ntawm PVC raw cov ntaub ntawv thiab ib qho ntawm cov khoom siv ntxiv (tsis muaj plasticizers) yog hu ua rigid polyvinyl chloride (hu ua UPVC).
Taw qhia ntawm piping system:
Ob leeg UPVC thiab CPVC piping systems muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, cuam tshuam tsis kam, tsis yooj yim rau deform, du sab hauv phab ntsa, tsis yooj yim rau scale, zoo thaum tshav kub kub preservation, tsis-conductive, yooj yim kev sib txuas, ntev kev pab cuam lub neej thiab hais txog.
Yog li ntawd, lwm cov kav dej hlau tau maj mam hloov los ntawm qhov zoo ntawm kev ua haujlwm siab thiab cov nqi tsim kho tsawg, thiab UPVC thiab CPVC piping systems yog yooj yim thiab ceev kom tswj tsis tau ntev downtime thiab ua rau poob loj. Yog li ntawd, UPVC thiab CPVC piping systems yog tam sim no muaj piping tsim. Nyiam.
Qhov siab tshaj plaws tso cai kub ntawm UPVC kav dej yog 60 degree, thiab kev siv mus sij hawm ntev yog 45 degree. Nws yog tsim rau conveying ib co corrosive media uas nws kub yog qis dua 45 degree; Nws kuj tseem siv tau rau kev xa cov kua dej ntau, feem ntau siv hauv cov kav dej thiab cov kav dej, cov kav dej ua liaj ua teb, cov kav dej ib puag ncig engineering, cov kav dej cua txias, thiab lwm yam.
Qhov siab tshaj plaws tso cai kub ntawm CPVC kav dej yog 110 degree, thiab lub sij hawm ntev siv kub yog 95 degree. Nws yog qhov tsim nyog rau kev thauj cov dej kub thiab cov xov xwm corrosive nyob rau hauv lub siab ntau yam tso cai los ntawm tus qauv. Feem ntau siv hauv roj av, tshuaj, hluav taws xob, hluav taws xob, metallurgy, papermaking, zaub mov thiab dej haus, tshuaj, electroplating thiab lwm yam kev lag luam.
