Thaum tswj cov saw hlau, nws yog ib qho tseem ceeb kom ntseeg tau tias lawv ua tau zoo tshaj plaws thiab siv tau ntev. Kev ntxuav thiab lubrication tsis tu ncua yog qhov tsim nyog los tiv thaiv xeb, cov khib nyiab sib sau ua ke thiab hnav. Txawm li cas los xij, qee zaum cov txheej txheem ntxuav ib txwm ua tsis tiav thiab peb yuav tsum siv lwm txoj hauv kev daws teeb meem, xws li siv hydrochloric acid. Hauv cov blog no, peb yuav tshawb nrhiav lub luag haujlwm ntawm hydrochloric acid hauv kev ntxuav cov saw hlau thiab muab cov lus qhia txog lub sijhawm zoo tshaj plaws rau kev ntxuav cov kua qaub no.
Kawm txog cov kua qaub hydrochloric:
Hydrochloric acid, tseem hu ua hydrochloric acid, yog ib yam tshuaj muaj zog uas feem ntau siv rau ntau yam kev ntxuav vim nws cov khoom muaj zog corrosive. Vim tias cov saw hlau feem ntau khaws cov roj, av thiab cov khib nyiab hauv cov chaw nyuaj mus txog, hydrochloric acid muab ib txoj hauv kev zoo los yaj cov tshuaj tawv ncauj no thiab rov qab ua haujlwm ntawm cov saw hlau.
Cov Lus Qhia Txog Kev Nyab Xeeb:
Ua ntej peb yuav tham txog seb cov saw hlau uas siv rau hauv cov kua qaub hydrochloric ntev npaum li cas, nws yog ib qho tseem ceeb uas yuav tsum xav txog kev nyab xeeb ua ntej. Cov kua qaub hydrochloric yog ib yam khoom txaus ntshai thiab yuav tsum tau ua tib zoo saib xyuas. Ib txwm hnav cov khoom siv tiv thaiv tus kheej (PPE) xws li hnab looj tes roj hmab, tsom iav, thiab lub ntsej muag thaum ua haujlwm nrog cov kua qaub no. Tsis tas li ntawd, xyuas kom tseeb tias cov txheej txheem ntxuav tau ua nyob rau hauv qhov chaw muaj cua zoo kom tsis txhob ua pa cov pa phem.
Lub sijhawm zoo tshaj plaws rau kev tsau dej:
Lub sijhawm zoo tshaj plaws rau cov saw hlau uas muab tso rau hauv cov kua qaub hydrochloric nyob ntawm ntau yam, suav nrog qhov xwm txheej ntawm cov saw hlau, qhov hnyav ntawm kev ua qias tuaj thiab qhov concentration ntawm cov kua qaub. Feem ntau, kev muab cov saw hlau tso rau hauv lub sijhawm ntev yuav ua rau muaj kev xeb ntau dhau, thaum kev tso dej tsis txaus yuav tsis tshem tawm cov av nplaum tawv ncauj.
Yuav kom ua tiav qhov sib npaug zoo, peb xav kom pib nrog lub sijhawm ntub dej li ntawm 30 feeb txog 1 teev. Thaum lub sijhawm no, xyuas seb cov saw hlau puas zoo li cas kom paub tseeb tias yuav tsum tau ntub dej ntev. Yog tias cov saw hlau qias neeg heev, koj yuav tsum maj mam nce lub sijhawm ntub dej hauv 15 feeb kom txog thaum tau txais qhov huv si raws li xav tau. Txawm li cas los xij, ceev faj tsis txhob ntub dej ntev tshaj plaub teev, lossis tej zaum yuav ua rau puas tsuaj uas kho tsis tau.
Kev saib xyuas tom qab tso dej:
Thaum cov saw hlau tau muab cov kua qaub hydrochloric tso rau hauv lub sijhawm uas xav tau, yuav tsum tau ceev faj kom tshem tawm cov kua qaub seem. Yaug cov saw hlau kom huv si nrog dej huv kom paub tseeb tias tshem tawm tag nrho. Tom qab ntawd, nws raug pom zoo kom muab cov saw hlau tso rau hauv dej thiab baking soda sib xyaw (ib diav baking soda rau ib liv dej) kom tshem tawm cov kua qaub seem. Qhov no yuav tiv thaiv kev xeb ntxiv thiab npaj cov saw hlau rau cov txheej txheem lubrication.
Hydrochloric acid tuaj yeem yog ib qho cuab yeej tseem ceeb hauv kev ntxuav cov saw hlau thaum cov txheej txheem ib txwm ua tsis tau raws li qhov xav tau. Los ntawm kev ceev faj thiab ua raws li lub sijhawm ntub dej pom zoo, koj tuaj yeem tshem tawm cov khoom tsis huv uas tsis ua rau koj cov saw hlau puas tsuaj. Nco ntsoov tias yuav tsum muab kev nyab xeeb tso ua ntej thoob plaws hauv cov txheej txheem ntxuav thiab muab kev saib xyuas tom qab ntub dej kom ntseeg tau tias koj cov saw hlau tau ntxuav thiab saib xyuas zoo.
