Tuam Tshoj chaw tsim tshuaj paus tsim dub phosphating qhuav phab ntsa rau tes, siab zog nws tus kheej tapping screws, hla countersunk taub hau teeb steel keel phab ntsa vaj huam sib luag rau tes rau fasteners-1

xov zoo
Phosphated drywall screws yog cov khoom lag luam yooj yim tshaj plaws, thaum xiav thiab dawb zinc drywall screws yog ib qho ntxiv, thiab lawv cov peev txheej ntawm daim ntawv thov thiab cov nqi yuav khoom yog tib yam. Qhov sib txawv me ntsis yog tias cov phosphating dub muaj qee qhov kev sib tw ntawm lubricity thiab zoo dua me ntsis nres ceev (qhov ceev ntawm cov ntawv teev thickness ntawm steel phaj yog nkag mus, uas yog qhov ntsuas qhov ntsuas qhov zoo); Xiav thiab dawb zinc muaj kev tiv thaiv xeb zoo dua me ntsis, thiab cov khoom siv xim ntuj yog lub teeb, ua rau nws tsis tshua muaj xim tom qab txheej txheej kho kom zoo nkauj.
Xiav dawb zinc thiab daj zinc yuav luag tsis muaj qhov sib txawv hauv kev tiv thaiv xeb, tsuas yog vim qhov sib txawv ntawm kev siv tus cwj pwm lossis cov neeg siv nyiam.
Ib kab ntxhib cov hniav
Cov xov ntawm ib kab ntxhib hniav txhuam hniav ntsia hlau yog dav dua, thiab qhov sib txuas ceev nrawm nrawm dua. Nyob rau tib lub sijhawm, vim tias nws yuav tsis ua rau cov qauv ntawm cov khoom siv ntoo nws tus kheej tom qab nkag mus rau hauv cov ntoo, nws yog qhov tsim nyog rau kev teeb tsa ntawm cov ntoo keel dua li ob kab zoo hniav phab ntsa ntsia hlau.
Nyob rau hauv txawv teb chaws, kev tsim kho feem ntau muab qhov tseem ceeb ntawm kev xaiv cov khoom fastener haum. Ib kab ntxhib hniav phab ntsa ntsia hlau yog ib txoj hauv kev zoo dua rau ob kab zoo hniav phab ntsa ntsia hlau rau txuas ntoo keels. Hauv kev ua lag luam hauv tsev, ob lub xov tooj zoo hniav phab ntsa ntub dej tau siv tshwj xeeb rau lub sijhawm ntev, thiab hloov cov cwj pwm siv yuav tsum tau qee lub sijhawm.
Self drilling ntsia hlau
Siv rau kev sib txuas ntawm gypsum board thiab hlau keel nrog lub thickness tsis tshaj 2.3mm, muaj nyob rau hauv dub phosphating thiab daj zinc txheej xaiv. Lub peev xwm ntawm daim ntawv thov thiab tus nqi yuav khoom ntawm ob qho tib si yog tib yam. Daj zinc muaj cov nyhuv tiv thaiv xeb zoo dua me ntsis, thiab cov khoom xim ntuj yog lub teeb, ua rau nws tsis tshua muaj xim tom qab txheej kho kom zoo nkauj.
