Dab tsi yog qhov ua rau pwm xeb?

Pwm xeb yog ib txwm tshwm sim thiab tshwm sim los ntawm cov laj thawj tshwj xeeb. Nws tsis yog ib qho teeb meem ntawm qhov zoo ntawm cov hlau. Hnub no kuv yuav qhia koj tias dab tsi ua rau pwm xeb.

Lub ntsiab ua rau pwm xeb thiab kev daws teeb meem:

(1) Gas generated los ntawm yaj decomposition (corrosive)

Qee cov khoom siv raw yuav tsim cov pa roj tsis haum thaum rhuab. Cov roj no yog corrosive thiab yuav corrode pwm. Yog li ntawd, nws yog ib qho tsim nyog los tswj qhov kub ntawm lub thoob kom tsis txhob overheat, thiab thaum cov khoom tsis ua hauj lwm, ntxuav lub pwm nrog ib tug mos ntaub thiab kaw lub pwm. Yog tias nws tsis siv sijhawm ntev, tshuaj tsuag cov tshuaj tiv thaiv xeb rau hauv cov pwm kab noj hniav, thiab thaum kaw cov pwm. Siv butter thiab ntsaws lub sprue.

(2) Cov dej txias hauv pwm

Cov dej txias feem ntau yog siv rau hauv pwm kom txias, yog li muaj ntau cov dej vapor nyob ib ncig ntawm cov khoom siv molding. Yog tias cov pwm txias hauv qab qhov dej lwg, cov dej noo hauv huab cua yuav tsim cov tee dej ntawm cov pwm. Yog tias tsis so rau lub sijhawm, nws yuav yooj yim xeb. Tshwj xeeb tshaj yog tom qab cov pwm tsis ua haujlwm, cov dej condensation yuav raug tsim sai. Yog li ntawd, thaum nres molding, cov dej txias yuav tsum tau muab tua thiab cov pwm yuav tsum tau wiped qhuav.

(3) Carbide tsim thaum lub sij hawm molding

Tom qab cov pwm tau ua haujlwm ntev, cov khoom siv molding yuav precipitate thiab decompose rau carbides, uas kuj corrosive rau ib yam dab tsi thiab feem ntau ua rau cov pwm hnav, corrode los yog xeb. Hauv qhov no, yog tias pom carbides tsim los yog cov dej ntws tawm, lawv yuav tsum tau muab tshem tawm tam sim ntawd.

(4) Cia ib puag ncig

Thaum lub sijhawm khaws cia, yog tias cov pwm khaws cia rau hauv qhov chaw ntub dej ntev, nws yog qhov yooj yim rau xeb. Nyob rau hauv no hais txog, peb yuav tsum tswj lub ambient humidity, khaws qhov chaw uas cov pwm yog khaws cia qhuav thiab ventilated, thiab tsis txhob muaj ib tug humid ib puag ncig.

(5) Cov txheej txheem siv

Yog tias cov pwm tsis raug saib xyuas zoo thiab khaws cia thaum siv, nws tseem yuav ua rau muaj teeb meem xeb. Hauv qhov no, thaum siv cov pwm, nws yog ib qho tsim nyog yuav tsum tau ntxiv dag zog rau kev saib xyuas thiab tu, ntxuav thiab siv cov roj los tiv thaiv xeb hauv lub sijhawm.

Txawm hais tias pwm xeb yog ib qho teeb meem tshwm sim, tsuav yog peb paub cov kev txhim kho kom raug, peb tuaj yeem zam qhov teeb meem no zoo, yog li ua kom lub neej kev pab cuam ntawm pwm thiab cov khoom zoo.
