Cov Khoom Siv Xaiv Cov Khoom Qhia rau Corrosion Kuj Tseem Tshuam Intrement Instrumental

Xaiv cov ntaub ntawv raug rau cov cuab yeej thiab cov khoom siv lag luam yog qhov tseem ceeb cuam tshuam rau kev ua haujlwm ncaj qha, ntev, thiab kev nyab xeeb ntawm koj lub systems.

Ib qho ntawm cov tseem ceeb tshaj plaws los txiav txim siab thaum xaiv cov khoom siv, kom muaj ntau qhov chaw muaj kev lag luam koom nrog kev ua phem thiab muaj tej yam mob hnyav. Kab lus no yuav tshawb cov khoom siv cov khoom sivMuaj Kev Ntsuam XyuasThiab lawv cov khoom siv corrosion, muab cov kev pom zoo muaj txiaj ntsig los pab koj ua kom txiav txim siab rau koj cov haujlwm.

Nkag siab corrosion tsis kam nyob rau hauv cov ntaub ntawv

Corrosion yog cov lus me me ntawm cov khoom siv los ntawm kev siv tshuaj lom neeg nrog lawv ib puag ncig. Cov ntaub ntawv sib txawv cov qauv sib txawv rau ntau cov neeg sawv cev sib txawv, xws li cov kua qaub, cov ntsev, ntsev, thiab txawm tias dej hiav txwv. Txhawm rau pab koj ua cov khoom siv zoo tshaj plaws rau koj qhov kev xav tau, peb mam li saib ntawm cov khoom lag luam corrosion tsis kam siv nws yog xim hlau thiab tsis yog xim hlau cov ntaub ntawv siv hauv kev lag luam.

Sib xwsNws yog xim hlau ntaub ntawv

Stainless hlau (304 thiab 316)
Stainless hlau yog ib qho ntawm cov khoom siv dav tshaj plaws hauv kev lag luam ua vim nws txoj kev txhim kho corrosion zoo heev thiab muaj zog.

304 Stainless hlau: paub txog qhov zoo tsis kam mus rau cov atmospheric, dej, thiab cov kua qaub me me, 304 stainless hlau ua zoo hauv cov ntawv thov me. Txawm li cas los xij, nws tsis haum rau cov accortrated acids, hauv paus, lossis muaj zog oxidizers.

316 Stainless hlau: los ntawm kev ntxiv Molybdenum, 316 Stainless hlau muaj kev txhim kho corrosion tawm tsam rau 304, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog chloride ions. Qhov no ua rau nws zoo tagnrho rau kev siv hauv cov ntawv thov marine lossis lwm qhov kev txhoj puab ib puag ncig.

Titanium thiab titanium alloys (ti)
Titanium muaj koob meej rau nws qhov tshwj xeeb tiv taus corrosion, tshwj xeeb tshaj yog hauv chlorides, organic acids, thiab alkalis. Nws ua tau zoo nyob rau hauv ntau qhov chaw ib puag ncig, suav nrog seasaterater, tab sis nws tsis tiv taus hydrofluoric acid, thiab qee cov kua qaub uas muaj zog sulfuric. Titanium alloys zoo li ti -0. 3mo}. 8NI thiab ti ua ntej

Tantalum (ta)
TANTATUM yog ib qho ntawm feem ntau corrosion-resistant hlau thiab feem ntau siv nyob rau hauv cov kev txhoj puab heev. Nws yog zoo ib yam li iav hais txog nws txoj kev tiv thaiv rau feem ntau cov tshuaj sawv cev feem ntau tab sis tsis tuaj yeem tiv taus hydrofluoric acid, fuming sulfuric acid, thiab alkalis.

Nickel alloys (piv txwv li, hastelloy)
Nickel-raws li alloys, xws li hastelloy, yog qhov zoo tshaj rau cov ntawv thov ua kom muaj ntau qhov chaw sov thiab muaj kev sib raug zoo. Cov alloys muab kev tiv thaiv zoo heev rau cov muaj zog acids muaj zog, hauv paus, thiab cov ntsev kua, ua rau lawv haum rau cov khoom siv tshuaj lom neeg.

Txhuas Alloys
Aluminium alloys nthuav qhia zoo corrosion corrosion, tshwj xeeb rau cov tshuaj lom neeg thiab kev ntxhov siab. Ntshiab txhuas (1xxx series) muaj qhov zoo tshaj plaws corrosion tsis kam, thaum txhuas alloys hauv 5xxx series tseem ua tau zoo. Txawm li cas los xij, alloys hauv 2xxx thiab 7xxx koob muaj kev cuam tshuam tau ntau dua rau corrosion.

Cov Khoom Uas Tsis Muaj Hlau: Cov Khoom Tseem Ceeb thiab Kuj

Daim yas

Thermoplastic plastics (piv txwv, PTFE): Cov plastics no tau muab tshuaj lom neeg zoo heev thiab tuaj yeem tiv thaiv txhua yam tshuaj lom neeg, ua rau lawv muaj zog rau cov khoom siv.

Thermoset plastics (piv txwv li, epoxy resins): thaum cov plastics no muaj cov khoom zoo corrosion, lawv feem ntau yog siv rau kev ua tsev thiab cov tshuaj insulating.

Cov Roj Hmab Hluav Taws Xob

Nitrile Roj Hmab (NBR): Paub txog nws cov roj thiab dej tsis yeem siv hauv cov ntsaws ruaj ruaj, muab kev tiv thaiv cov pa roj ntau, hauv paus, thiab roj.

Rooj ceramics
Ceramics yog cov nquag tiv thaiv kom kub thiab tshuaj lom neeg, ua rau lawv haum rau kev siv cov ntsuas kub siab. Txawm li cas los xij, lawv muaj nkig thiab nquag los ua kom tawg hauv kev poob siab, yog li lawv feem ntau siv nyob rau hauv cov chaw uas tsis yauv siv tshuab kev ntxhov siab.

Cov lus hauv qab no muab kev sib piv ntawm cov kev sib piv ntawm corrosion resistance cov yam ntxwv ntawm ntau alloys thiab cov ntaub ntawv feem ntau siv hauv kev ntsuas:

Yuav ua li cas xaiv cov khoom zoo rau koj daim ntawv thov

Thaum xaiv cov khoom zoo rau koj cov twj paj nruag, nws yog qhov tseem ceeb uas yuav tau txiav txim siab ntau yam:

Tshuaj lom neeg ib puag ncig: Txheeb xyuas cov tshuaj yuav tuaj rau hauv kev sib cuag nrog. Cov hlau zoo li titanium thiab npib tsib xee yog qhov zoo tagnrho rau cov hlau txhoj puab, thaum stainless hlau yog haum rau kev loj hlob.

Qhov kub thiab txias: Kev siv kub nyob ib puag ncig zoo li ceramics lossis qee cov alloys uas tuaj yeem tiv taus thermal kev nyuaj siab yam tsis muaj corroding.

Kev Nyuaj Siab: Yog tias cov ntaub ntawv yuav raug rau cov rog tseem ceeb, xav txog lub zog thiab brittleness ntawm cov khoom. Piv txwv li, titanium alloys muaj zoo corrosion tsis kam tab sis tej zaum yuav tsis muaj peev xwm ruaj khov hauv qab kev sib piv rau lwm cov ntaub ntawv li stainless hlau.

Tus nqi thiab kev muaj: qee cov ntaub ntawv, xws li hastelloy lossis tantalum, tuaj yeem kim thiab tsis tsim nyog rau txhua daim ntawv thov. Stainless hlau thiab qee qhov plastics muab cov tshuaj zoo dua rau cov ntawv thov cov laj thawj dav dav.
