Dab tsi yog qhov yuav tsum tau ua kom huv rau cam khwb cia aluminium heaters

Thaum lub sij hawm kneading thiab txiav txheej txheem ntawm lub plhaub, kawg npog, tub ntxhais, thiab txhaj tshuaj yeeb nkab, cov qhov chaw ntawm lub cam khwb cia aluminium rhaub yuav inevitably raug paug. Piv txwv li, thaum kneading lub puab groove raj, lub lubricant yuav nyob twj ywm nyob rau hauv lub raj, thiab thaum machining lwm qhov chaw, lub lubricant kuj yuav kis tau los ntawm cov roj thiab lwm yam pa phem. Yog tias lub tshuab hluav taws xob cam khwb cia aluminium tau qhia, tsis yog tsuas yog cov dej ntub dej ntawm qhov ua haujlwm nruab nrab tsis zoo, tab sis qhov nruab nrab ua haujlwm nws tus kheej kuj yuav kis tau thiab kev hloov pauv yuav txo qis.
Kev ua haujlwm ntawm cam khwb cia aluminium heaters feem ntau tso qee cov khib nyiab hlau rau hauv lub casing, thiab rau lub sijhawm ntev, cov plua plav loj tau ntim rau hauv cov kav dej. Yog tias tsis kho, lub capillary channel yuav raug thaiv. Cov dej seem nyob rau hauv txhuas thiab stainless steel tube shells reacts nrog lub raj phab ntsa los tsim cov khoom tsis yog gases, uas tsis tsuas yog corrodes lub raj plhaub tab sis kuj thaiv cov condensation seem, ua rau cov cua sov yeeb nkab tsis ua hauj lwm zoo.
Tsis tas li ntawd, ntxuav qhov vuam ntawm qhov chaw. Qhov vuam zoo yog ze ze rau qhov kev huv huv ntawm qhov chaw. Cov txheej txheem ntxuav feem ntau suav nrog degreasing, deoxidation, thiab ziab. Cov kuab tshuaj (cawv, carbon tetrachloride, thiab lwm yam) tuaj yeem siv rau kev tshem tawm cov roj thiab tshuaj lom neeg tshem tawm (sodium hydroxide tov, thiab lwm yam). Kev tshem tawm ntawm oxide zaj duab xis nyob ntawm cov ntaub ntawv. Aluminium alloys tuaj yeem siv cov tshuaj alkaline. Tooj liab, tooj liab alloys, thiab stainless hlau tuaj yeem corroded los ntawm acid. Cov chaw tsim khoom ntawm casting tooj liab cua sov muab cov cuab yeej tu rau aluminium alloys, tooj liab alloys, thiab stainless hlau ntawm no. Tau kawg, lwm txoj kev tsim nyog kuj siv tau.
Nws yuav tsum tau muab sau tseg tias ob qho tib si acid thiab alkali ntxuav yuav tsum tsis txhob yuav tsum tau nqa tawm rau lub sij hawm ntev los tiv thaiv corrosion ntau heev, tshwj xeeb tshaj yog nyob rau hauv axial thiab kauv grooves. Kev xeb ntau dhau tuaj yeem nthuav dav grooves thiab txo cov capillary rog. Feem ntau siv tooj liab mesh, nrog ib tug me me conductor txoj kab uas hla thiab tsis siv pickling. Tom qab immersion nyob rau hauv hnyav, roj yuav raug tshem tawm. Sab hauv ntawm sintered tube tub ntxhais yog huv heev thiab tsis tas yuav tsum tau ntxuav. Yog tias yuav tsum tau ntxuav, nws tuaj yeem tsau rau hauv cov kuab tshuaj thiab ci rau lub sijhawm ntev kom evaporate cov kuab tshuaj seem hauv cov tub ntxhais.
Tsis tas li ntawd, caustic soda thiab acid muaj qhov sib txawv corrosiveness, yog li emitting cov pa phem thaum lub sij hawm ntxuav. Piv txwv li, thaum tooj liab cuam tshuam nrog acids, gradient gases raug tso tawm. Thaum cov roj tso tawm ntev dhau los ntawm cov kua qaub, cov kua qaub yuav tsim. Yog li ntawd, ntxuav nyob rau hauv ib tug zoo ventilated ib puag ncig.
