Nws tuaj yeem tiv taus xeb los ntawm ntau yam inorganic acids, organic acids, thiab cov kuab tshuaj organic tshwj tsis yog hydrofluoric acid, nrog rau kev tiv taus kua qaub ntawm ≤ 99% thiab kev tiv taus alkali ntawm ≤ 85%. Tus nqi pheej yig heev, thiab muaj ntau yam kev qhia tshwj xeeb xaiv los ntawm, xws li φ 16, φ 25, φ 38, φ 50, φ 76, φ 80, φ 100, thiab lwm yam, uas tuaj yeem siv rau ntau qhov xwm txheej kub thiab qis thiab muaj ntau yam kev siv.
Lub nplhaib yas pall
Cov txiaj ntsig:Nws yog lub teeb yuag, tsis yooj yim tawg, tiv taus kub thiab tshuaj lom neeg, tus nqi tsim khoom nruab nrab, porosity siab, qhov siab qis thiab qhov siab hloov pauv loj, qhov chaw dej nyab siab, kev sib cuag roj-kua txaus, kev hloov pauv loj ua haujlwm tau zoo. Qhov kub ntawm kev siv hauv ntau yam xov xwm yog 60-280 ℃, siv dav hauv kev lag luam xws li roj av, tshuaj lom neeg, chlorine alkali, roj thiab kev tiv thaiv ib puag ncig.
Qhov Tsis Zoo:Tsis tiv taus kub siab, muaj zog acids thiab alkalis thiab yooj yim rau oxidation.
Cov ntaub ntawv sib txawv thiab cov yam ntxwv:
PP(polypropylene): tiv taus cua sov rau 100 ° C, tus nqi qis dua, tab sis tsis tshua muaj zog tiv taus corrosion.
RPP(Polypropylene uas muaj zog): Raws li PP, lub zog kho tshuab thiab kev tiv thaiv kev hnav tau raug txhim kho los ntawm kev hloov kho qhov txhawb nqa, ua rau nws tsim nyog dua rau cov ntawv thov uas xav tau lub zog kho tshuab siab.
PVC(polyvinyl chloride): Nws muaj kev tiv thaiv xeb zoo rau tshuaj lom neeg, tab sis nws qhov kub thiab txias tsis kam yog txwv.
CPVC(Chlorinated Polyvinyl Chloride): Nws muaj kev kam rau qhov kub siab dua li PP, feem ntau ncav cuag li 110 ° C, thiab muaj kev tiv thaiv xeb zoo.
PVDF(polyvinylidene fluoride): Nws tuaj yeem tiv taus qhov kub thiab txias txog li 150 ° C thiab muaj kev tiv thaiv xeb zoo heev, ua rau nws tsim nyog rau kev siv mus sij hawm ntev hauv cov chaw ua haujlwm hnyav.
PTFE(Polytetrafluoroethylene): Nws tuaj yeem tiv taus qhov kub txog li 260 ° C thiab tam sim no yog ib qho ntawm cov ntaub ntawv tiv taus xeb tshaj plaws, tshwj xeeb tshaj yog haum rau cov txheej txheem tshuaj lom neeg kub thiab corrosive heev.
Lub nplhaib hlau pall
Cov txiaj ntsig:Phab ntsa nyias nyias, tiv taus cua sov thiab txias, porosity siab, flux siab, txo qis siab, tsis kam, zoo sib cais, lub neej ntev, thiab tuaj yeem siv tag nrho lub peev xwm ntawm cov khoom siv. Haum rau cov tshuab nqus tsev distillation, cov pa roj carbon dioxide degassing, tuav cov ntaub ntawv uas ua xua, yooj yim decompose, yooj yim compact, thiab yooj yim rau carbon deposition, siv dav hauv cov thawv ntim khoom hauv kev lag luam xws li petrochemicals, chiv, tshuaj, thiab kev tiv thaiv ib puag ncig.
Qhov Tsis Zoo:Tsis resistant rau cov kua qaub thiab alkalis muaj zog.
Cov ntaub ntawv sib txawv thiab cov yam ntxwv:
Cov hlau carbon:tus nqi qis dua, tab sis tsis muaj zog tiv thaiv corrosion, haum rau qee qhov kev ua haujlwm nrog kev tiv thaiv corrosion tsis muaj zog.
304 stainless hlau:Nws muaj kev tiv taus xeb zoo thiab tiv taus kub, thiab siv tau ruaj khov hauv ntau yam tshuaj lom neeg. Nws yog cov khoom siv hlau pob nplhaib feem ntau siv.
316L stainless hlau:Kev tiv thaiv xeb zoo dua li 304 stainless hlau, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas muaj zog corrosiveness xws li chloride ions. 316L stainless hlau muaj cov pa roj carbon tsawg dua thiab kev ua haujlwm vuam zoo dua, uas tuaj yeem txo cov teeb meem intergranular corrosion uas yuav tshwm sim thaum lub sijhawm vuam.
