I. Khoom yam ntxwv:
PVC yog ua los ntawm vinyl chloride monomer (VCM) polymerization, PVC cov khoom muaj cov yam ntxwv tsis muaj tshuaj lom, tiv thaiv kev laus thiab cov kua qaub thiab alkali tsis kam, yog li nws yog qhov tsim nyog rau kev siv tshuaj yeeb dej caw.Thiab nrog PVC raw cov ntaub ntawv los ntxiv ib co ntawm cov khoom additives (tsis muaj plasticizer) muaj pes tsawg leeg ntawm cov sib tov, hu ua nyuaj polyvinyl chloride (hu ua UPVC).
CPVC yog cov khoom siv polymer hloov kho los ntawm chlorination ntawm polyvinyl chloride (PVC) dua.Tom qab chlorination, cov ntsiab lus chlorine ntawm PVC resin nce ntawm 56.7% mus rau 63-69%, uas ua rau kom cov tshuaj ruaj khov thiab yog li txhim kho cov cua sov thiab corrosion kuj ntawm acid, alkali, ntsev thiab oxidant ntawm cov khoom.Nws thermal deformation kub thiab txhua yam khoom muaj ntau dua li cov UPVC.Yog li, CPVC yog ib qho ntawm cov khoom siv engineering zoo tshaj plaws rau cov kav dej.
2. Pipeline system qhia:
UPVC thiab CPVC kav dej muaj kev tiv thaiv corrosion, cuam tshuam tsis kam, tsis yooj yim rau deformation, du sab hauv phab ntsa, tsis yooj yim rau scale, zoo thermal rwb thaiv tsev, tsis-conductive, yooj yim sib txuas, ntev kev pab cuam lub neej thiab lwm yam ntxwv.Yog li ntawd, nws maj mam hloov lwm cov kav dej hlau ntawm qhov zoo ntawm cov nqi siab thiab kev tsim kho qis, thiab UPVC thiab CPVC piping systems yog qhov yooj yim thiab ceev ceev, tsis muaj sijhawm poob thiab poob loj, yog li UPVC thiab CPVC piping systems yog thawj qhov kev xaiv. rau tam sim no industrial piping tsim.
Qhov siab tshaj plaws kev pabcuam kub ntawm UPVC piping system yog 60 ℃, thiab lub sijhawm ntev kev pabcuam kub yog 45 ℃.Nws yog tsim rau conveying ib co corrosive media nrog kub qis dua 45 ℃;Nws tseem tuaj yeem siv rau kev thauj mus los ntawm cov kua dej zoo tib yam, 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 kev pabcuam kub ntawm CPVC piping system yog 110 ℃, thiab lub sijhawm ntev kev pabcuam kub yog 95 ℃.Nws yog tsim rau conveying dej kub thiab corrosive media nyob rau hauv lub tso cai siab ntau yam ntawm tus qauv.Feem ntau siv rau hauv roj av, tshuaj, hluav taws xob, hluav taws xob, metallurgy, ntawv, zaub mov thiab dej haus, tshuaj, electroplating thiab lwm yam kev lag luam
