Cov Khoom Siv thiab Kev Zoo
Thaum siv cov yeeb nkab tooj dag hauv cov kav dej kub, nws yog ib qho tseem ceeb uas yuav tsum tau them sai sai rau cov khoom siv thiab qhov zoo ntawm cov khoom siv. Cov yeeb nkab tooj dag feem ntau yog ua los ntawm cov hlau sib xyaw ntawm tooj liab thiab zinc, uas muab kev tiv thaiv corrosion zoo heev thiab lub zog kub siab. Nws yog ib qho tseem ceeb kom ntseeg tau tias cov khoom siv tooj dag siv yog qhov zoo thiab ua raws li cov qauv kev lag luam kom tiv thaiv cov teeb meem xws li xau lossis ua tsis tiav ua ntej.
Kev Sib Tw Nrog Dej Kub
Qhov sib xws ntawm cov yeeb nkab tooj dag thiab dej kub yog qhov tseem ceeb uas yuav tsum xav txog. Tooj dag paub txog nws lub peev xwm tiv taus qhov kub siab, ua rau nws tsim nyog siv rau hauv cov kav dej kub. Txawm li cas los xij, nws yog ib qho tseem ceeb kom paub tseeb tias cov khoom siv tooj dag tshwj xeeb uas siv yog tsim los rau kev siv dej kub. Qhov no ua kom ntseeg tau tias cov khoom siv tuaj yeem ua tau zoo rau qhov kub thiab siab ntawm lub kaw lus dej kub yam tsis muaj kev cuam tshuam rau lawv qhov kev ua tiav.
Kev Loj thiab Kev Teeb tsa Kom Zoo
Qhov loj thiab kev teeb tsa cov yeeb nkab tooj dag kom raug yog qhov tseem ceeb rau kev ua haujlwm zoo thiab muaj kev nyab xeeb ntawm cov kav dej kub. Nws yog ib qho tseem ceeb uas yuav tsum xaiv cov khoom siv uas yog qhov loj thiab hom raug rau daim ntawv thov yeeb nkab kub tshwj xeeb. Tsis tas li ntawd, kev teeb tsa cov yeeb nkab tooj dag yuav tsum tau ua raws li kev coj ua zoo tshaj plaws hauv kev lag luam thiab cov lus qhia ntawm cov chaw tsim khoom kom tiv thaiv cov teeb meem xws li xau lossis kev puas tsuaj ntawm cov qauv.
Kev Tiv Thaiv Galvanic Corrosion
Kev xeb galvanic tuaj yeem tshwm sim thaum cov hlau sib txawv sib chwv nrog ib leeg thaum muaj electrolyte, xws li dej kub. Thaum siv cov yeeb nkab tooj dag hauv cov kav dej kub, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov muaj peev xwm rau kev xeb galvanic thiab ua cov kev ntsuas tiv thaiv. Qhov no tuaj yeem ua tiav los ntawm kev siv cov dielectric unions lossis insulating gaskets los cais cov yeeb nkab tooj dag ntawm lwm cov hlau hauv cov kav dej, yog li txo qhov kev pheej hmoo ntawm kev xeb thiab ntev lub neej kev pabcuam ntawm cov yeeb nkab.
Kev Zoo ntawm Dej thiab Kev Sib Xws ntawm Cov Tshuaj
Qhov zoo ntawm cov dej thiab nws cov tshuaj lom neeg muaj pes tsawg leeg tuaj yeem cuam tshuam rau kev ua haujlwm thiab lub neej ntev ntawm cov yeeb nkab tooj dag hauv cov kav dej kub. Nws yog ib qho tseem ceeb uas yuav tsum xav txog cov yam xws li pH, cov ntsiab lus ntawm cov zaub mov, thiab qhov muaj cov tshuaj corrosive hauv cov dej kub. Kev kuaj dej thiab kev tshuaj xyuas tsis tu ncua tuaj yeem pab txheeb xyuas txhua yam teeb meem uas yuav cuam tshuam rau cov yeeb nkab tooj dag thiab tso cai rau kev ntsuas tsim nyog los txo cov teebmeem tsis zoo.
Kev Txij Nkawm thiab Kev Tshuaj Xyuas
Kev saib xyuas thiab tshuaj xyuas cov yeeb nkab tooj dag hauv cov kav dej kub tsis tu ncua yog qhov tseem ceeb kom ntseeg tau tias lawv ua haujlwm tau zoo thiab ruaj khov. Yuav tsum tau tshuaj xyuas thiab kuaj xyuas qhov xau kom paub txog cov cim ntawm kev hnav, xeb, lossis kev puas tsuaj. Tsis tas li ntawd, kev saib xyuas ua ntej xws li kev ntxuav, kev roj nplua nyeem, thiab kev zawm cov yeeb nkab tuaj yeem pab tiv thaiv teeb meem thiab ua kom lub neej ua haujlwm ntawm cov yeeb nkab tooj dag ntev dua.
Kev Ua Raws Cai thiab Cov Qauv
Thaum siv cov yeeb nkab tooj dag hauv cov kav dej kub, nws yog ib qho tseem ceeb kom ua raws li cov cai thiab cov qauv. Qhov no suav nrog kev ua raws li cov cai tsim kho, cov lus qhia ntawm kev lag luam, thiab cov ntawv pov thawj khoom. Los ntawm kev siv cov khoom siv tooj dag uas ua tau raws li lossis tshaj qhov yuav tsum tau ua ntawm cov cai, kev ncaj ncees thiab kev nyab xeeb ntawm cov kav dej kub tuaj yeem ua tau, muab kev thaj yeeb nyab xeeb rau cov neeg siv thiab cov neeg koom nrog.
