Cov ntsia hlau uas tsis yog tus qauv tau coj txoj haujlwm tseem ceeb hauv niaj hnub no' cov khoom tsim khoom lag luam. Cov khoom lag luam zoo yuav tsum tsis txhob raug tsim thiab lees txais nruj raws li cov qauv sib xws.Dab tsi yog cov qauv kev lees paub rau cov ntsia hlau tsis yog qauv?
Ua ntej ntawm tag nrho cov, tsis yog-tus qauv screws kuj yog cov evolution ntawm lub teb chaws standard screws. Cov khoom tshuaj ntsuam xyuas tshwj xeeb yuav tsum tau txiav txim siab raws li lub teb chaws tus qauv ntsia hlau nto defect qauv. Thov xa mus rau cov qauv hauv tebchaws uas sib raug rau kom paub meej. Yog tias cov txheej txheej saum npoo los yog plating cuam tshuam rau kev txheeb xyuas ntawm qhov tsis xws luag, koj yuav tsum Xaiv tawm ua ntej kev tshuaj xyuas.
Thib ob, tshuaj xyuas qhov ntev thiab cov khoom siv ntawm cov ntsia hlau uas tsis yog tus qauv raws li qhov yuav tsum tau ua ntawm cov duab kos duab. Qhov no yuav tsum tau ua tib zoo saib xyuas cov khoom siv. Ua ntej, cov khoom lag luam raw khoom yuav tsum muab cov ntaub ntawv pov thawj daim ntawv tshaj tawm. Thib ob, cov khoom siv high-end yuav tsum tau ntawv pov thawj SGSmaterial, thiab xa mus rau cov chaw soj nstuam cuam tshuam rau cov khoom siv tshuaj ntsuam xyuas kom paub meej tias cov ntsiab lus muaj pes tsawg leeg ua tau raws li cov khoom xav tau ntawm cov duab kos.
Lub luag haujlwm yuav tsum tau tshuaj xyuas tsis muaj kev puas tsuaj dua. Yog tias ib feem ntawm cov ntsia hlau tsis yog tus qauv pom tau tias muaj cov kab nrib pleb tawg, wrinkles ntawm qhov chaw txhawb nqa thiab hauv qab, thiab seb cov txheej puas ua tau raws li cov cai tiv thaiv Roshenvironmental.
Tom qab ntawd muaj kev sim ua kom puas tsuaj. Piv txwv li, qib hardness ntawm cov ntsia hlau uas tsis yog tus qauv yog raug rau qhov sib thooj hardness cuam tshuam kev kuaj; sab hauv hardness, mechanical zog, torsion test, thiab lwm yam., yuav ua rau cov screws uas tsis yog-tus qauv, tab sis qhov no yog tag nrho rau cov ntsia hlau factories nrog lub tswv yim muaj zog. zoo. Yuav tsum ua cov khoom xeem.
