Qee lub sij hawm Xiao Bian yuav ntsib ib los yog ob tug neeg nug, seb lub chaw screws, los yog qee tus nug seb puas muaj M4 tsis quav ntsev. Cov ntsia hlau yog tiag tiag tsis nyob rau hauv Tshuag thiab nws yog kev cai tsim. Cov neeg ua lag luam yuav tsum tau muab cov khoom siv coj los sib txuas, yuav tsum tau siv peb cov khoom siv, tus txheej txheem peb xav tsim cov kev cai, tab sis qhov chaw ntawd tsis yog tiag tiag. Qee lub khw muag khoom (shì chǎng) yog loj heev, thiab nws yog tus nqi ntau dua kom yuav qhov khoom ntawd tshaj qhov nws tau siv. Ntxiv mus, qee lub teb chaws tus qauv tsis nquag siv, thiab lawv kuj yuav tsum tau ua kev cai vim hais tias kev siv ntawm cov screws tsis siab, thiab ntau lub lag luam tsis muaj cov khoom. Yog li ntawd, thaum saib cov kab xev fais fab, nco ntsoov them rau cov teeb meem no (Emerson).
Thaum muaj coob tus neeg siv cov khoom qaum, feem ntau ntawm cov ntaub ntawv siv yog cov tsis muaj qab ntxiag hlau (stainless acid-resistant steel). Vim li cas? Qhov no tsis yog vim hais tias cov hlau tsis muaj steel hlau (stainless acid-resistant steel) muaj cov kab xeb thiab corrosion-resistant, tab sis nws kuj muaj zoo ductility thiab muaj qee yam kom zoo dua hauv cov txheej txheem tsim. Cov ntsuas tsis yog tus qauv siv cov khoom fais fab thiab kev ua zauv ntawm qhov khoom siv qhov khoom tig thiab kev sib txhuam, thiab ua raws li cov cuab yeej cuab tam. Screws yog ib lub ntsiab lus rau cov fasteners, hais txhua hnub. Stainless hlau ntsia thawv yog hais txog cov duab ntawm ib lub ntsia hlau ua ntawm stainless hlau ntsia hlau hlau tus pas nrig, thiab nws yog threaded nyob rau hauv lub tsheb. Nws cov khoom yog stainless hlau. Stainless hlau screws faib rau stainless hlau SUS201 screws, stainless hlau SUS304 screws, thiab stainless hlau SUS316 screws. Txoj kab plaub hau tsuas tsis muaj lub taub hau me me xwb, tab sis kuj muaj lub me me ntsia hlau, lub luv luv ntsia hlau ntev, thiab lub nrig me me, thiab qee qhov kev ntsuas screws yuav tsum ignored. Precision ntswj ntau lawm thiab kev tsim cov txheej txheem yuav tsum yog qhov tseeb, raws li kev cai kam rau ua, kev xav tau me me thiab lwm yam sib txawv heev. Rau kev siv pej xeem siv, feem ntau cov khoom (Khoom) yuav siv stainless hlau (Khoom) raws li cov xaim rau kev ua screws tsis muaj kev tshwj xeeb. Tsis tas li ntawd, lub stainless hlau screws tsuas yog yuav tsum tau ntxuav tom qab ntau lawm, thiab cov tsos yuav heev ci, piv nrog cov carbon. Stainless hlau screws yog zoo heev, tab sis kuj muaj ib yam anti-rust nyhuv, yog li stainless hlau screws feem ntau tsis yuav tsum tau, yuav tsuas yog ntxuav (chǔ lǐ). Thaum stainless hlau screws siv rau plating los yog lwm qhov kev kho saum npoo, khawb yuav tshwm sim. Qhov no yog vim plating tsis yog kev kho mob ntawm ib qho tshuaj, tab sis tus ntsuas yog tag nrho ua ke rau electroplating. Li ntawd, koj tsis tuaj yeem tsoo bumping, thiab nws yooj yim tawm hauv khawb ntawm kov. Ua rau muaj kev txhawm rau hauv lub hau ntswj. Tsis tas li ntawd, txoj hlua hlau tsis muaj cov hlau tsis muaj qab hau tom qab ntxuav tau tuaj yeem ua raws li cov kev cai ntawm kev siv, thiab cov nqi ntawm cov nqi tsis tsim nyog yuav tsum muaj siab. Yog li, ntau tus neeg siv cov stainless hlau screws.
