Hauv kev soj ntsuam ib puag ncig, kev nyab xeeb hauv kev lag luam, thiab kev tshuaj xyuas hauv chaw kuaj mob,cov twj tso kua cua me meyog cov khoom tseem ceeb hauv cov txheej txheem kuaj roj. Thaum tshuaj xyuas cov pa roj corrosive, kev xaiv cov khoom siv twj tso kua mis cuam tshuam ncaj qha rau qhov tseeb ntawm cov txiaj ntsig tshuaj xyuas thiab lub neej ua haujlwm ntawm cov khoom siv. Kev xaiv cov khoom siv tsis raug tuaj yeem ua rau cov ntaub ntawv zoo tsis zoo thiab txawm tias ua rautwj tso kua mis me me dcua tsis tiav.

Tsab xov xwm no muab ib qho lus qhia meej thiab siv tau rau kev xaiv cov khoom siv hauv txoj kev yooj yim.

Lub Ntsiab Cai Tseem Ceeb: Tsuas Yog Tsom Mus Rau Cov Cheebtsam Uas Sib Chwv Nrog Roj

Hauv cov twj me me, tsuas yog cov khoom uas kov cov roj ncaj qha xwb thiaj li yuav tsum tau xav txog kev tiv taus xeb. Cov no feem ntau hu ua cov khoom "wet end" thiab feem ntau suav nrog:

1, Lub Taub Hau Twj Tso Kua Mis/Lub Npog: Muab kev txhawb nqa cov qauv thiab muaj thaj chaw sib cuag loj tshaj plaws nrog cov roj.

2, Diaphragm: Lub luag haujlwm rau kev hloov roj, xav tau kev ywj pheej zoo thiab kev qaug zog.

3, Cov Phaj Valve / Cov Valves: Tswj cov kev taw qhia ntawm cov roj ntws, xav tau cov lus teb sai thiab kev sib khi zoo.

Cov Khoom Tseem Ceeb: Cov Cheebtsam "Qhov Kawg Nkaus" - Kev Xaiv Ntawm Cov Yas thiab Elastomers

Cov khoom "wet end" feem ntau yog cov khoom siv xws li cov yas ua haujlwm siab (siv rau cov taub hau twj tso kua mis) thiab cov elastomers ua haujlwm siab (siv raucov diaphragms thiab cov li qub). Hauv qab no, peb yuav nkag siab txog cov yam ntxwv ntawm cov ntaub ntawv no nrog rau kev tsom mus rau cov khoom "ntub kawg".

Cov Khoom Siv Taub Hau Twj Tso Kua Mis: Kev Sib Npaug Lub Zog thiab Kev Tiv Thaiv Kev Xeb

Lub Npe Khoom Siv	Kev luv luv	Cov Yam Ntxwv Tseem Ceeb thiab Cov Ntawv Thov	Cov Hom Roj Uas Tsim Nyog
Polyphenylene Sulfide	PPS	Kev ua tau zoo tag nrho. Lub zog kho tshuab siab, tiv taus cua sov zoo, thiab ua tau ntau yam rau cov kua qaub, alkalis, thiab cov kuab tshuaj. Feem ntau siv rau hauv feem ntau cov pa roj flue (SO₂, NOx).	Cov kua qaub tsis muaj zog, cov alkali tsis muaj zog, cov kuab tshuaj feem ntau
Polyvinylidene Fluoride	PVDF	Haum rau cov oxidizers muaj zog. Kev tiv taus zoo heev rau cov pa roj oxidizing muaj zog xws li Cl₂, O₃, thiab cov kua qaub muaj zog.	Cov tshuaj oxidizing muaj zog, cov kua qaub muaj zog
Polytetrafluoroethylene	PTFE	Tsis muaj zog tshuaj lom neeg. Yuav luag tsis muaj zog nrog txhua yam tshuaj lom neeg. Haum rau cov chaw uas xav tau qhov huv tshaj plaws lossis nrog cov pa roj sib xyaw ua ke.	Yuav luag txhua yam tshuaj lom neeg

Cov Lus Qhia Siv Tau: Yog tias cov pa roj muaj cov tshuaj chlorine lossis ozone ntau, nws raug pom zoo kom xaiv lub taub hau twj tso kua mis PVDF lossis PTFE, zam PPS.

Cov Khoom Siv Diaphragm/Valve: Kev Sib Npaug ntawm Elasticity thiab Stability

Cov diaphragms thiab cov li qub yuav tsum tau elastic thaum tseem ua corrosion-resistant.

Lub Npe Khoom Siv	Kev luv luv	Cov Yam Ntxwv Tseem Ceeb thiab Cov Ntawv Thov	Tus nqi thiab kev siv tau
Polyphenylene Sulfide	EPDM	Tus nqi qis dua. Zoo tiv taus cov kua qaub, alkalis, thiab cov pa dej. Txawm li cas los xij, nws tsis zoo tiv taus cov roj thiab feem ntau cov kuab tshuaj organic (VOCs).	Tus nqi qis, tsim nyog rau cov pa roj corrosive ib txwm muaj uas tsis muaj VOCs.
Polyvinylidene Fluoride	FKM	Siv tau ntau yam. Tsis yooj yim rau cov kuab tshuaj organic, hydrocarbons (VOCs), thiab cov kua qaub muaj zog. Ib qho elastomer uas siv ntau hauv kev tshuaj xyuas kev lag luam.	Tus nqi nruab nrab, kev ua tau zoo txhim khu kev qha, tsim rau feem ntau qhov chaw ua haujlwm.
Polytetrafluoroethylene	FFKM	Kev tiv thaiv xeb zoo tshaj plaws. Kev ua haujlwm tshuaj lom neeg ze rau PTFE thaum tswj cov roj hmab elasticity. Tiv taus yuav luag txhua yam tshuaj lom neeg.	Tus nqi siab heev, tsuas yog siv rau cov ntawv thov hnyav heev, cov haujlwm tseem ceeb uas tsis tuaj yeem cuam tshuam.

Cov Lus Qhia Siv Tau: Yog tias cov roj muaj cov hydrocarbons lossis cov organic solvents (VOCs), tsis txhob xaiv EPDM. Hloov chaw, xaiv FKM lossis FFKM.

Cov Txheej Txheem Txiav Txim Siab Peb Kauj Ruam: Yuav Ua Li Cas Xaiv Kom Yog?

Kev xaiv cov khoom siv tsis yog hais txog kev xaiv qhov kim tshaj plaws, tab sis yog hais txog kev phim qhov xwm txheej tiag tiag.

Kauj Ruam 1: Txheeb Xyuas Cov Khoom Siv thiab Kev Ntsuas ntawm Cov Pa roj

Qhov no yog lub hauv paus tseem ceeb tshaj plaws rau kev xaiv cov khoom siv. Koj yuav tsum paub txog cov khoom uas muaj zog tshaj plaws hauv cov roj uas yuav ntsuas thiab nws qhov concentration siab tshaj plaws.

• Piv txwv Ib: Cov pa roj av ib txwm muaj (SO₂, NOx uas muaj cov pa roj tsawg): Lub taub hau twj PPS + FKM diaphragm/valves.
• Piv Txwv Ob: Kev tshuaj xyuas Chlorine hauv cov nroj tsuag chlor-alkali (Cl₂ uas muaj ntau qhov concentration): PVDF lub taub hau twj tso kua mis + FFKM diaphragm/valves.

Kauj Ruam 2: Xav Txog Qhov Cuam Tshuam Ntawm Qhov Kub

Kub ua rau xeb sai dua. Cov khoom siv uas tiv taus kub hauv chav tsev yuav puas sai thaum kub siab. Ib txwm saib cov ntawv qhia txog kev sib raug zoo ntawm cov khoom siv raws li qhov kub ua haujlwm tiag tiag.

Kauj Ruam 3: Sib Npaug Tus Nqi thiab Kev Pheej Hmoo

• Kev Pheej Hmoo Tsawg / Kev Siv Ib Txwm: Xaiv qhov kev sib xyaw ua ke PPS/FKM rau qhov piv ntawm kev siv nyiaj thiab kev ua tau zoo tshaj plaws.
• Kev Siv Uas Muaj Kev Pheej Hmoo / Tseem Ceeb: Xaiv qhov kev sib xyaw ua ke ntawm PVDF/PTFE/FFKM. Txawm hais tias kev nqis peev thawj zaug siab dua, nws muab lub neej ua haujlwm ntev dua thiab kev ntseeg siab dua rau kev tshuaj xyuas, ua pov thawj tias pheej yig dua rau lub sijhawm ntev.

Kev Ceeb ToomHauv kev tshuaj xyuas cov roj corrosive, kev sib raug zoo ntawm cov khoom siv yog qhov tseem ceeb. Kev ua tsis tiav ntawm cov khoom siv tsis tsuas yog ua rau muaj kev puas tsuaj xwbtwj tso kua me metab sis tej zaum kuj nyob rau hauv ib pawg ntawm cov ntaub ntawv tshuaj xyuas tsis raug.
