Self-tapping ntsia hlauyog ib hom ntsia hlau nrog lub laum me ntsis, uas yog tsim los ntawm cov cuab yeej hluav taws xob tshwj xeeb, drilling, tapping, kho thiab ntsuas phoo yog ua tiav ib zaug. Self-tapping screws yog tsuas yog siv rau kev sib txuas thiab kho ntawm qee qhov phaj nyias, xws li kev sib txuas ntawm cov xim hlau phaj thiab xim hlau phaj, kev sib txuas ntawm cov xim hlau phaj thiab purlin, phab ntsa beam, thiab lwm yam, thiab nws cov peev xwm nkag tau. feem ntau tsis ntau tshaj 6 hli, thiab qhov siab tshaj plaws yog tsis ntau tshaj 12 hli.
Self-tapping screws feem ntau raug rau sab nraum zoov thiab muaj zog corrosion kuj; Cov roj hmab sealing nplhaib tuaj yeem ua kom ntseeg tau tias cov ntsia hlau tsis pom dej thiab muaj kev tiv thaiv corrosion zoo. Self-tapping screws feem ntau tau piav qhia los ntawm peb qhov tsis muaj: ntsia hlau txoj kab uas hla series, xov tooj ntawm ib nti ntev thiab ntsia hlau ntev. Muaj cov chav kawm 10 thiab 12 ntsia hlau, thiab cov ntsia hlau sib txuas yog 4.87mm thiab 5.43mm feem. Tus naj npawb ntawm cov xov ib nti ntev muaj 14, 16, 24 peb theem, qhov ntau ntawm cov xov ib nti ntev, qhov muaj zog ntawm nws tus kheej drilling peev xwm.
Txawm hais tias muaj ntau yam ntawm tus kheej tapping screws, lawv txhua tus muaj cov yam ntxwv tseem ceeb hauv qab no:
(1) Lawv feem ntau yog ua los ntawm cov hlau carburized (suav txog 99% ntawm tag nrho cov khoom). Nws tuaj yeem ua los ntawm cov hlau tsis muaj hlau lossis cov hlau tsis muaj hlau.
(2) Cov ntsia hlau yuav tsum tau kho cua sov. Carbon steel self-tapping screws yuav tsum tau carburized, stainless hlau nws tus kheej tapping screws yuav tsum yog cov khoom hardening kev kho mob. Txhawm rau ua kom tus kheej tapping ntsia hlau kom ua tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem kev siv tshuab thiab kev ua haujlwm.
(3) Lub screws nto hardness yog siab, lub hauv paus toughness yog zoo. Ntawd yog, "mos hauv tab sis tawv sab nraud." Qhov no yog qhov tseem ceeb ntawm kev ua haujlwm ntawm tus kheej tapping screws. Yog hais tias qhov saum npoo hardness tsawg, nws tsis tuaj yeem ntsia hlau rau hauv matrix; Xws li cov tub ntxhais toughness tsis zoo, ib qho kev sib tw yuav tawg, siv tsis tau. Yog li ntawd, "mos sab hauv thiab nruj sab nraud" yog tus kheej-tapping ntsia hlau kom ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm.
(4) Qhov saum npoo ntawm cov khoom yuav tsum tau kho qhov chaw tiv thaiv, feem ntau electroplating kho. Qhov saum npoo ntawm qee cov khoom yuav tsum tau kho nrog phosphate (phosphating). Piv txwv li: phab ntsa vaj huam sib luag tapping screws feem ntau yog phosphating.
(5) Nws yog tsim los ntawm cov txheej txheem txias. Nws raug nquahu kom siv lub tshuab ua kom txias txias thiab lub tshuab hluav taws xob kub ceev lossis lub tshuab hluav taws xob ceev ceev kom paub meej cov khoom zoo. Lub taub hau ntawm tus kheej tapping ntsia hlau tsim nyob rau hauv txoj kev no yog tsim tau zoo thiab cov xov zoo yog siab.
