1. Muaj feem xyuam thiab cov qauv khoom
Cov khoom yog tsim nyob rau hauv raws li Suav teb chaws tus qauv fastener specifications. Lub taub hau countersunk muaj Phillips tus kheej-drilling qauv. Tom qab xauv lub taub hau, lub taub hau ntsia hlau tau muab tso rau hauv lub phaj, thiab qhov saum npoo yog du thiab tsis muaj bulges. Nws yog dav siv nyob rau hauv lub teeb steel keel qab nthab, qhov rooj thiab qhov rais kho vajtse los ua ke, sab hauv tsev ntawv hlau sab hauv kho kom zoo nkauj, lub teeb steel thav ntawv, rooj tog hlau ntawv connectors, thiab aluminium alloy auxiliary khoom fixation. Cov khoom lag luam tau raug xa tawm ntev mus rau cov khoom siv kho vajtse thiab cov khoom siv hauv tsev lag luam ntawm Middle East, Southeast Asia, thiab Africa. Nws los nrog ib qho kev xyaum taw tes, tsis tas yuav tho qhov ua ntej, thiab nws tuaj yeem ua tau raws li kev ua haujlwm dual kev xav tau ntawm cov ntawv nyias nyias thiab cov ntawv ntoo.
2. Kev xaiv cov khoom siv thiab cov txheej txheem ntau lawm
Cov khoom siv raw yog cov pa roj carbon zoo thiab siv cov kev kho cua sov tag nrho. Lub hardness ntawm lub laum taw tes txiav ntug ncav cuag tus qauv, lub drilling yog ntse, thiab lub drilling yog resistant rau chipping los yog tawg ntawm lub laum taw tes. Cov txheej txheem ntau lawm: Kaum txheej txheem suav nrog kev kos duab ntxhib ntawm cov khoom siv raw, annealing, phosphating, kos duab zoo, txias taub hau, taw tes ua, xov dov, kev kho cua sov, zinc plating, thiab ntim. Lub Phillips recesses yog nruj nreem kaw, thiab cov ntsia hlau ua haujlwm tsis yooj yim rau plam thiab kev puas tsuaj; cov qauv xov yog tsis tu ncua, ntsia hlau rau hauv cov khoom siv hauv paus, thiab qhov tom yog ruaj, thiab nws yog resistant rau loosening tom qab lub sij hawm ntev kev co. Cov xim xiav zinc txheej yog ntom thiab sib xws.
3. Cov khoom tseem ceeb zoo
Concealed installation ntawm countersunk taub hau: tapered ca taub hau tsim. Tom qab ua tiav, ntsia hlau taub hau saum npoo yog yaug nrog lub workpiece yam tsis muaj protrusions thiab khawb. Nws yog qhov zoo dua rau cov haujlwm sab hauv thiab rooj tog zaum uas yuav tsum tau ua kom zoo nkauj.
Self-drilling thiab dual-lub hom phiaj: Lub hau yog nruab nrog lub laum hniav, uas tuaj yeem xyaum ncaj qha los ntawm 0.5 ~ 5mm txias-kuav los tiag steel nplooj ntawv thiab zinc plated hlau los xij. Nws kuj tseem tuaj yeem ua tus kheej tho cov khoom ntoo thiab cov rooj zaum ntom ntom. Nws muaj ntau yam kev siv thiab txo cov naj npawb ntawm cov khoom muag.
4. Kev tswj cov khoom lag luam zoo thiab cov kev pabcuam txhawb nqa
Tag nrho cov lus qhia tshwj xeeb yog nyob rau hauv Tshuag, kev txiav txim tsis tu ncua raug xa tawm hauv 48 teev, thiab cov qauv txiav txim thiab tag nrho cov thawv xa tawm tau txais. Lub laum taw tes hardness, Phillips recess zog, xov raug, thiab txheej adhesion yog soj ntsuam cov khoom los ntawm cov khoom ua ntej tawm hauv lub Hoobkas, thiab cov outflow ntawm cov khoom puas yog nruj me ntsis tswj. Nws tuaj yeem raug xa mus ua ke nrog peb lub Hoobkas lub tshuab ntxhua khaub ncaws thiab lub caij nplooj ntoos hlav ntxhua khaub ncaws, thiab muab cov khoom siv ib-nres fastening; nws txhawb customized extension rods thiab tshwj xeeb hniav-hom nonstandard nws tus kheej-drilling screws, thiab ruaj khov muaj peev xwm ua kom muaj kev txiav txim mus sij hawm ntev rau cov neeg muas zaub txawv teb chaws.
