Piv nrog rau lwm yam bolts thiab screws, stainless hlau bolts thiab stainless hlau screws muaj ntau yam ntawm daim ntaub ntawv sau tsis tshua muaj qhov kub thiab kub qhov chaw, yog li hlau screws tau ua ntau dua thiab nrov dua nyob hauv kev siv. Cov nram qab no yog cov cuab yeej ntsia hlau tsis ua hauj lwm thiab kev tiv thaiv kev txhawm rau:
Ua ntej, qhov txaus ntshai ntawm kho vajtse screw tsis ua hauj lwm
Feem ntau, cov hlau thiab hlau alloy steel hauv qab plag tsis raws li qhov chaw muaj cov khoom siv khoob khiab thiab thinning, thiab cov hlau tsis txhuam tsis muaj zog nyob rau hauv cov xwm txheej uas yuav luag tsis pom hloov ntawm qhov chaw, ua rau muaj kev puas tsuaj rau cov qauv lossis khoom . Qhov nws tsis ua hauj lwm yog ntau insidious thiab teeb meem.
Thib ob, txoj kev los tiv thaiv kev txhuam hniav ntawm lub ntsuas vaj tse
1. Siv cov khoom siv hlau tsis muaj hlua khi kom tsis txhob muaj qhov sib txawv hauv cov qauv tsim thiab tsis txhob muaj cov kab mob uas ua rau thaj chaw yooj yim;
2, stainless hlau ntsia hlau thiab Cl-muaj kua rau kev rho tawm, tsis tuaj yeem kom tsis txhob kis, los ntawm stainless hlau ntsia hlau los tiv thaiv corrosion nyhuv to taub, yuav tsum tau welded los yog sau cov kis, kom cov kua aqueous tsis nkag mus;
3. Siv cov hlau tsis muaj stainless nrog high chromium thiab molybdenum siab, tshwj xeeb tshaj yog nyob rau thaj tsam uas tsis tshua kub, lub cheeb tsam kheej kheej, thiab txoj kev ntxhov siab nyob hauv cheeb tsam loj, cov hlau nrog kev txhim kho corrosion zoo dua.
