Cov Qhov Zoo Ntawm Cov Kav Dej Welded Hauv Kev Tsim Kho Cov Kav Dej Nroj Tsuag

Cov Zoo Ntawm Cov Kav Dej Sib Txuas Hauv Kev Tsim Kho Cov Kav Dej Nroj Tsuag

Kev Piav Qhia Luv:

Thaum tsim cov kav dej roj av, kev xaiv cov khoom siv thiab cov txheej txheem tsim khoom yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb, kev ntseeg siab thiab lub neej ntev ntawm cov khoom siv. Ib qho ntawm cov kev daws teeb meem zoo tshaj plaws thiab muaj txiaj ntsig zoo hauv kev lag luam yog kev siv cov yeeb nkab hlau uas tau vuam ua ke, ib hom yeeb nkab vuam uas muaj ntau yam zoo rau kev xa roj av.

Cov kav dej uas vuam ua voj voog yog tsim los ntawm kev siv cov txheej txheem uas cov hlau raug vuam thiab txuas ntxiv mus ua ib lub voj voog. Txoj kev no tsim cov kav dej muaj zog, ruaj khov thiab yoog tau uas zoo tshaj plaws rau kev thauj mus los roj av.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov yeeb nkab vuam uas muaj kauv yog nws qhov sib piv ntawm lub zog thiab qhov hnyav. Qhov no ua rau nws zoo tagnrho rau cov kav dej ntev vim nws tuaj yeem tiv taus qhov siab sab hauv thiab sab nraud uas siv thaum lub sijhawm thauj roj ntuj yam tsis muaj kev cuam tshuam rau kev ua haujlwm ntawm cov qauv. Tsis tas li ntawd, cov txheej txheem vuam kauv ua kom ntseeg tau tias qhov tuab ntawm phab ntsa ntawm cov yeeb nkab sib npaug, ua rau nws lub zog thiab kev tiv thaiv kev hloov pauv.

Tsis tas li ntawd xwb, cov kav hlau txuas nrog kauv muaj kev tiv thaiv corrosion zoo heev, uas yog qhov tseem ceeb hauvcov yeeb nkab roj avkev tsim kho. Cov khoom siv hlau uas muaj nrog rau cov txheej txheem thiab cov ntaub thaiv ua rau cov kav dej no tiv taus cov teeb meem corrosive ntawm cov roj av thiab lwm yam kuab paug uas muaj nyob hauv ib puag ncig. Qhov no tsis yog tsuas yog ua kom lub neej ntawm cov kav dej ntev xwb, tab sis kuj txo cov kev xav tau kev saib xyuas thiab cov nqi cuam tshuam.

Ntxiv rau nws cov khoom siv kho tshuab thiab tiv taus xeb, cov yeeb nkab vuam kauv yog qhov zoo tagnrho rau kev teeb tsa hauv ntau thaj chaw thiab cov xwm txheej ib puag ncig. Nws qhov kev ywj pheej ua rau yooj yim dua rau kev txav mus los thiab kev teeb tsa nyob ib puag ncig cov khoom thaiv, ua rau nws yog qhov kev xaiv pheej yig rau cov toj roob hauv pes nyuaj. Tsis tas li ntawd, cov pob qij txha vuam ntawm cov yeeb nkab vuam kauv yog qhov muaj zog, ua kom ntseeg tau tias cov yeeb nkab tsis xau thoob plaws lawv lub neej kev pabcuam.

Lwm qhov zoo ntawm cov yeeb nkab vuam uas muaj kauv yog nws tus nqi tsim nyog.
