Insulating khob, tsuas yog saib cov tsos tsis txaus
Oct 14, 2023
Lub hauv paus ntsiab lus qab lub khob rwb thaiv tsev yog tsis complex. Stainless hlau rwb thaiv tsev khob yog ob txheej txheej, thiab ob txheej ntawm stainless hlau ntawm lub khob lub cev thiab sab hauv liner yog welded thiab ua ke los tsim lub tshuab nqus tsev, uas tsis hloov cov cua sov;
Plating nyiaj los yog tooj liab ntawm ob txheej ntawm stainless hlau ntawm lub khob lub cev thiab sab hauv liner kom txo tau hluav taws xob poob ntawm tshav kub; Tsis tas li ntawd, cov qaib ntxhw ntawm lub khob rwb thaiv tsev muaj kev sib khi zoo, uas tuaj yeem txo qhov poob ntawm cov cua sov los ntawm convection.
Lub khob rwb thaiv tsev tsis tsuas yog nyob ntawm nws cov tsos, tab sis thaum koj tuav nws hauv xib teg ntawm koj txhais tes thiab haus dej nrog nws, koj yuav pom tias cov khoom tseem ceeb dua li nws cov tsos.
Tam sim no, feem ntau lub khob rwb thaiv tsev yog ua los ntawm stainless hlau, uas feem ntau muab faib ua peb hom, nrog rau cov lej 201, 304, thiab 316.
201 stainless hlau: nrog cov ntsiab lus siab manganese, tsis zoo corrosion kuj, thiab tus nqi qis, nws tsuas yog siv tau rau hauv kev tsim cov khoom lag luam. Yog hais tias siv nyob rau hauv lub puab liner ntawm rwb thaiv tsev khob, nws tuaj yeem yooj yim ua rau manganese nag lossis daus thiab ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv.
304 stainless hlau: Nws belongs rau cov zaub mov qib stainless hlau thiab muaj 18% chromium thiab 8% npib tsib xee. Nws yog acid resistant thiab muaj zoo corrosion kuj. Txawm li cas los xij, cov khoom uas muaj chloride ions yog qhov ua rau pitting corrosion.
316 stainless hlau: Raws li lub hauv paus ntawm 304 stainless hlau, muaj ib qho ntxiv hlau molybdenum, uas muaj corrosion kuj zoo dua, tab sis tus nqi kuj siab, thiab feem ntau yog siv nyob rau hauv high-precision thiab txiav-ntug teb xws li kev kho mob. thiab chemical engineering.
Txhua tus muaj kev txhawj xeeb heev txog kev xaiv cov khoom tsis tsim nyog. Thaum muas lub khob rwb thaiv tsev, qee cov neeg hais tias lub khob rwb thaiv tsev uas tuaj yeem nqus tau los ntawm cov hlau nplaum yog qhov zoo. Qhov no puas muaj tseeb?
Tam sim no, feem ntau siv 304 thiab 316 stainless hlau nyob rau hauv kev ua lag luam yog cov hlau tsis sib nqus austenitic stainless hlau, uas feem ntau muaj cov hlau kim, npib tsib xee, thiab chromium ua alloying ntsiab; Txawm tias austenitic stainless hlau nrog tsawg nickel thiab manganese cov ntsiab lus tsis muaj hlau nplaum. Txawm hais tias nws yog pheej yig dua, nws txoj kev nyab xeeb thiab kev ua haujlwm tsis zoo, yog li cov hlau nplaum tsis tuaj yeem siv los ntsuas qhov zoo ntawm lub khob rwb thaiv tsev.
