Dej phwj yog cov khoom siv hnyav hauv cov dej phwj tuaj. Cov khoom xaiv ncaj qha cuam tshuam rau lawv corrosion tsis kam, cov khoom siv nyob hauv lub neej, thiab cov khoom siv tsis zoo, thiab hnav tsis kam, nrog rau kev siv zog kho tshuab. Tam sim no, cov ntaub ntawv tseem ceeb uas siv rau cov kua dej lim dej suav nrog cov hlau cam khwb cia, thiab cov khoom sib xyaw, nrog cov khoom sib txawv, nrog cov khoom sib txawv rau cov chaw ua haujlwm txawv.
1. Nrum Hlau
Cam khwb cia hlau (xws li cov hlau grey cam thiab hlau hlau) yog cov khoom siv uas siv hauv cov hmoov nplej. Nws muaj kev muaj zog txhua lub zog thiab tus nqi qis, ua rau nws haum rau kev kho kom dav dav thiab kev kho kom muaj kev lag luam pov tseg. Cov ntsej muag txho khoom siv hlau tsis kim tab sis kev ua kom cov khoom tsis muaj zog tiv thaiv corrosion tsis kam, ua rau nws tau siv tsawg dua hauv cov chaw pov tseg kom tsawg. Lub zog ua kom muaj zog dua thiab cov tawv tawv rau cov hlau cam khwb cia xim, ua kom haum rau kev siv nrog cov kev ntsuas siab dua thiab kev poob siab. Txawm li cas los xij, nws corrosion kuj tseem txwv tseem ceeb, thiab nws feem ntau yuav tsum tau txheej txheej txheej lossis cov ntaub qhwv rau kev txhim kho lub zog.
2. Stainless hlau
Stainless hlau (xws li 304, 316, thiab lub dhaus tsis muaj roj ua kom tsis txhob muaj cov tshuaj lim dej uas yuav tsum tau ua rau chloside ion corrosion thiab haum rau saline lossis siab heev Acidic lim dej. Duplex stainless hlau (xws li 2205) ua ke cov txiaj ntsig ntawm Austenite thiab pitting ua zog, xws li kev kho cov tshuaj lom neeg tshuaj lom neeg. Txawm li cas los xij, tus nqi siab ntawm stainless hlau txwv tsis pub nws siv hauv qee cov ntawv thov kev lag luam kev txiav txim siab.
3. Engineering plastics
Kev tsim kho cov pa roj fluorics (xws li polyvinylidene fluoride (PV), thiab ultra {0} {{0} {{migh {0} {{{{ PVDF muaj cov tshuaj ua tau zoo heev thiab yog qhov tsim nyog rau kev siv nyob rau hauv ib puag ncig nrog cov muaj zog acids, hauv paus, thiab cov kuab tshuaj. Txawm li cas los xij, nws tus nqi siab ua rau nws siv tau hauv kev kho tshwj xeeb kom loj. PP yas yog tus nqi qis {{4} tus nqi thiab haum rau dav dav yog neeg txom nyem, thiab lub siab} kev ua haujlwm kub yuav ua rau muaj kev cuam tshuam. UHMWPE muaj qhov tshwj xeeb hnav tsis kam thiab haum rau dej khib nyiab uas muaj cov khoom muaj zog ntau, xws li kuv cov dej ntws tawm.
4. Cov ntaub ntawv sib xyaw thiab cov thev naus laus zis
Txhawm rau sib npaug tus nqi thiab corrosion tsis kam, muaj ntau yam dej khib nyiab siv cov hlau corrosion (xws li roj hmab, epoxy cob, epoxy cob, lossis ceramic). Cov kab roj hmab muaj cov ris thiab corrosion tsis kam thiab haum rau wastewater muaj cov khoom muaj; Epoxy Txheej ci txhim kho lub twj tso kua mis ua haujlwm; thiab cov ntaub qhwv cov ceramic yog qhov tsim nyog rau cov ARURIVITY muaj ARGAST. Composite cov kev daws teeb meem tuaj yeem ua kom zoo nqi thiab ua tau zoo raws li kev ua haujlwm tshwj xeeb, txuas lub neej lub neej.
Tag
Cov khoom xaiv rau cov twj tso kua mis kom muaj kev sib cav txog cov khoom siv pov tseg, cov lus pov tseg, cov ntsiab lus kub, thiab ib puag ncig kub. Cov hlau cam khwb cia yog haum rau kev ua haujlwm dav dav, stainless hlau rau cov txheej txheem xeb zoo, thiab cov tshuab uas tsim kom haum rau cov kev siv hluav taws xob ua kom muaj zog. Cov ntaub ntawv sib xyaw ua cov kev daws teeb meem. Cov kev xaiv tsim nyog ntawm tsis tuaj yeem txhim kho qhov tsis muaj zog ntawm cov kav dej phwj, tab sis kuj yuav txo cov nqi kho thiab ua haujlwm tau zoo thiab ruaj khov ntawm cov dej phwj.
