Muaj pes tsawg lub sij hawm qhov kev tso cai ntawm lub zog hluav taws xob ntawm cov hluav taws xob cua sov yog cov khoom siv zoo tib yam?

Muaj pes tsawg lub sij hawm qhov kev tso cai ntawm lub zog hluav taws xob ntawm cov hluav taws xob cua sov yog cov khoom siv zoo tib yam?
Lub tshuab hluav taws xob hluav taws xob cua sov yog qhov txhab nrog lub tshuab hluav taws xob hlau rau ntawm qhov chaw ntawm cov khoom siv tib yam, thiab thaj chaw tshav kub dissipation yog loj dua li ntawm 2 mus rau 3 npaug ntawm cov khoom siv zoo tib yam, uas yog, qhov tso cai rau lub zog ntawm lub fin. yog 3 mus rau 4 npaug ntawm cov khoom zoo tib yam. Vim lub shortening ntawm qhov ntev ntawm cov khoom, lub tshav kub poob ntawm cov khoom yog txo. Nyob rau hauv tib lub zog, cov qauv siv hluav taws xob muaj qhov zoo ntawm cov cua kub ceev, cov cua sov tsis sib xws, cov cua sov ua haujlwm zoo, kev ua haujlwm siab thermal, kev pab lub neej ntev, cov khoom siv cua sov me me, tus nqi qis, thiab lwm yam.

Filling khoom nrog siab thermal conductivity

Nws tuaj yeem tsis tsuas yog ua kom cov thermal conductivity thiab txo cov thermal inertia, tab sis kuj tseem muaj txiaj ntsig ntau dua. Piv txwv li, qhov me me ntawm inertia, qhov me me ntawm qhov tshwm sim ntawm cov cua sov hauv lub raj, thiab qhov siab dua qhov hluav taws xob cua sov ntawm cov khoom cua sov; thiab qhov qis dua cov cua sov hauv lub raj, cov rwb thaiv tsev yuav ua tsis tau Qhov tsawg dua qhov ua tau, los yog qhov me me ntawm cov xau tam sim no, qhov kev nyab xeeb dua tag nrho lub tshuab yuav ua haujlwm thiab lwm yam.

Dab tsi yog cov kev ntsuas los tiv thaiv pitting corrosion ntawm stainless hlau hluav taws xob cua sov raj?

1. Thaum siv lub tank dej, ntxiv ib qho me me ntawm corrosion inhibitor, xws li qee cov pa oxygen (xws li hydroxide, nitrate, thiab lwm yam), los tiv thaiv pitting corrosion.

2. nruj me ntsis tswj cov khawb lossis khawb hauv lub tank sab hauv thaum lub sijhawm tsim khoom. Kev sib piv ntawm cov teebmeem ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov tob ntawm qhov khawb ntawm qhov kev ua haujlwm tiv thaiv corrosion ntawm lub tank sab hauv qhia tau hais tias tus nqi corrosion nce ntxiv thaum qhov khawb qhov tob yog 0.05mm. Yog li ntawd, qhov saum npoo ntawm cov hlau phaj yog nruj me ntsis tiv thaiv thaum lub sij hawm stainless hlau ua, thiab khawb uas yuav tsum tau kov los ntawm txhais tes tsis pub. cim.

3. Nyob rau theem pib, stainless hlau pickling passivation muab tshuaj txhuam tau siv los kho ib pawg ntawm ib txwm welded stainless hlau kuaj. Piv nrog rau cov qauv tsis kho rau pitting corrosion kuj, nws tau pom tias pitting corrosion kuj zoo heev, thiab tus nqi poob poob los ntawm 2.91 feem pua ​​​​rau 1.04 feem pua.

4. Nyob rau hauv hluav taws xob dej rhaub, siv ib txwm magnesium rods los yog kuj magnesium rods raws li ib tug ncej (anode) ntawm cov electrochemical cov tshuaj tiv thaiv saw yuav corroded los ntawm corrosion ions nyob rau hauv dej ua ntej stainless hlau, yog li txo qhov kev puas tsuaj ntawm corrosion ions rau cov hlau nyob rau hauv lub tank. Ncua lub corrosion ceev thiab lub zog ntawm lub puab hlau. Fais fab-on-corrosion, siv cathodic anti-corrosion txoj kev kom muaj peev xwm qis dua pitting corrosion muaj peev xwm.
