Screws tsis muaj qhov ruaj khov "lub neej txee." Lawv qhov kev siv tau yog nyob ntawm qhov chaw khaws cia thiab ib puag ncig uas lawv siv, tsis yog lawv hnub tsim khoom. Yog tias khaws cia kom zoo, steel screws lawv tus kheej yuav tsis deteriorate thiab tuaj yeem muab khaws cia rau lub sijhawm ntev.
Txawm li cas los xij, cov ntsiab lus hauv qab no cuam tshuam ncaj qha rau kev siv ntawm screws:
Tiv thaiv xeb: Cov ntsia hlau yuav tsum muab cia rau hauv qhov chaw qhuav, chav - qhov kub thiab txias hauv tsev. Qhov saum npoo yuav tsum tau coated nrog xeb-cov roj tiv thaiv thiab kaw kom tsis txhob muaj cua nkag mus thiab ua rau xeb. Nyob rau hauv ib qho chaw ntub dej, cov ntsia hlau tsis tau qhib tuaj yeem pom tev ntawm txheej galvanized li ntawm rau lub hlis; thaum nyob rau hauv qhuav, kaw tej yam kev mob, lawv tseem yuav siv tau ib txwm mus txog rau tsib xyoos.
Kev Tshuaj Xyuas Kev Pom Zoo: Yog tias cov ntsia hlau pom xeb ntau dua 3 hli, cov roj tsim hauv cov xov, los yog txoj kab uas hla ntau dua 0.2 hli, lawv yuav tsum muab pov tseg tam sim ntawd. Qhov no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv siab -kev nyab xeeb- qhov yuav tsum tau muaj xws li kev tsim kho thiab kev lag luam tshuaj, qhov uas siv cov ntsia hlau tsis zoo tuaj yeem ua rau muaj xwm txheej loj.
Material thiab Environmental Matching: Ib puag ncig sib txawv xav tau cov khoom sib txawv. Piv txwv li, 316 stainless hlau raug pom zoo rau cov chaw ntug dej hiav txwv, thaum cov kua qaub thiab alkali- cov ntaub ntawv resistant yuav tsum tau xaiv rau cov tshuaj ib puag ncig kom ntev lawv lub neej kev pab.
Kev pheej hmoo rov qab siv dua: Txawm hais tias qee qhov fasteners tuaj yeem raug tshem tawm thiab rov siv dua, nws raug nquahu kom hloov cov ntsia hlau disassembled nrog cov tshiab, tshwj xeeb tshaj yog siab - lub zog screws, vim kev ntxhov siab sab hauv lossis hydrogen embrittlement tuaj yeem ua rau ncua kev puas tsuaj.
