Kauv welded kav (ssaw) yog stacked sab nraum zoov, thiab lawv feem ntau yog faus rau hauv av thaum siv, yog li lawv yooj yim rau corrode thiab xeb. Txhawm rau kom ntseeg tau tias qhov dej ntws zoo ntawm cov kav dej, cov kav dej welded yuav tsum muaj kev tiv thaiv corrosion. Thaum lub raj xa dej tau corroded, nws yuav ua rau cov roj thiab cov pa tawm, uas yuav tsis tsuas cuam tshuam kev thauj mus los, tab sis kuj ua rau muaj kuab paug rau ib puag ncig, thiab tej zaum yuav ua rau hluav taws kub thiab muaj kev puas tsuaj. Kauv welded yeeb nkab manufacturers yuav qhia rau koj txog yam uas ua rau corrosion ntawm kauv welded kav:

Yog vim li cas rau xeb ntawm kauv welded yeeb nkab:

1. Corrosion tsis ua hauj lwm.

Thaum txhim kho cov kav dej, nws yog ib qho tsim nyog yuav tsum ua txoj haujlwm zoo ntawm kev tiv thaiv corrosion los yog siv ncaj qha los tiv thaiv corrosion kauv steel kav. Yog vim li cas rau corrosion ntawm lub raj xa dej yog tias cov txheej txheem tiv thaiv corrosion ntawm cov kav dej tau raug puas lawm. Thaum cov txheej txheem tiv thaiv corrosion thiab qhov chaw ntawm cov raj xa dej sib cais, nws yuav ua rau muaj kev tiv thaiv corrosion tsis ua haujlwm. Qhov no kuj yog hom ntaiv. Peb yuav tsum xaiv cov khoom siv tiv thaiv corrosion welded yeeb nkab thaum yuav khoom kauv welded yeeb nkab.

2. Kev cuam tshuam ntawm sab nraud.

Qhov tseem ceeb tshaj plaws yog ua ntej saib cov yam ntxwv thiab qhov kub thiab txias ntawm qhov nruab nrab nyob ib ncig ntawm lub raj xa dej, thiab seb qhov nruab nrab nyob ib ncig ntawm lub raj xa dej puas yog corrosive. Vim hais tias corrosiveness ntawm nruab nrab yog ze ze rau ntau yam kab mob uas muaj nyob rau hauv cov av. Thiab yog tias nws yog cov kav dej ntev ntev, qhov xwm txheej ntawm av ib puag ncig yog qhov nyuaj dua. Tsis tas li ntawd, qhov kub thiab txias ntawm ib puag ncig qhov chaw nyob ntawm cov kav dej yuav cuam tshuam rau corrosion ntawm cov kauv welded yeeb nkab. Yog tias qhov kub siab dua, tus nqi corrosion yuav nrawm dua, thaum qhov kub thiab txias qis dua, tus nqi corrosion yuav qeeb.
