Hla galvanized lub taub hau nws tus kheej tapping ntsia hlau yog cov khoom siv sib txuas nrog cov haujlwm hauv qab no thiab cov yam ntxwv:
1. Kev ua tau zoo fastening: Tus ntoo khaub lig loj lub taub hau nws tus kheej tapping screws yog ua los ntawm cov ntaub ntawv muaj zog, uas tuaj yeem ua tau zoo nruj cov khoom sib txawv ua ke thiab tswj cov khoom ruaj khov.
2. Yooj yim rau disassemble: Nrog nws lub taub hau tshwj xeeb tsim, nws tuaj yeem yooj yim nruj los yog disassembled siv lub hau ntswj, txuag cov kauj ruam ntawm kev xuas nrig ntaus ua ntej, ua rau nws yooj yim dua rau siv thiab txuag sij hawm.
3. Muaj zog corrosion kuj: Hla zoo li lub taub hau nws tus kheej tapping screws feem ntau yog ua los ntawm cov ntaub ntawv zoo, thiab cov khoom siv tshuaj kho tau los ua cov xim dub galvanized oxide zaj duab xis, uas muaj cov xeb zoo thiab tiv thaiv corrosion thiab tuaj yeem siv tau ntev hauv qhov chaw hnyav.
4. Cov qauv yooj yim: tsim los ntawm lub taub hau, ncej, thiab threaded qhov chaw, yooj yim rau kev tsim thiab siv.
5. Muaj feem xyuam: Nws muaj ntau yam kev siv hauv cov cuab yeej siv tshuab, kev tsim vaj tsev, rooj tog tsim khoom, khoom siv hluav taws xob, aerospace thiab lwm yam kev lag luam.
6. Lub zog ntau dua: Lub taub hau tiaj tus ntoo khaub lig zoo li lub taub hau tso cai rau tus ntoo khaub lig zoo li lub taub hau nws tus kheej tapping ntsia hlau kom zoo dua nrog cov khoom siv hauv paus, ua rau kev sib txuas ruaj khov thiab txhim khu kev qha, muaj peev xwm thauj khoom ntau dua, thiab zoo dua tensile thiab shear resistance dua li cov tsoos screws.
7. Kev ruaj ntseg siab dua: Lub tiaj tus ntoo khaub lig zoo li lub taub hau ua rau kev sib txuas ruaj khov thiab txhim khu kev qha, txo qhov muaj peev xwm ntawm loosening.
