Screws yuav tsum yog ib qho chaw rau peb. Cov neeg uas them nyiaj ntau dua rau qhov kev nthuav dav yuav tau them ntau dua rau cov ntsia hlau uas siv los tsim lawv cov cuab yeej los yog khoom siv. Dab tsi yog cov ntaub ntawv raw siv los ua peb? Dab tsi yog qhov ntsia hlau yuav tsum muaj rau lub lag luam (shì chǎng)? Tej kev ua xyem xyav yuav tshwm sim vim hais tias peb tsuas yog siv nws hauv kev nthuav dav thaum peb paub txog cov ntsiab lus ntawm ib yam, thiab peb yuav ua li cas tiv thaiv txoj kev siv nws (guò chéng). (xim) qhov chaw.
Tiag tiag, yog peb mus rau kev ua lag luam thiab kawm nws, peb yuav paub tias cov ntsuas peb siv tam sim no yog tsim los ntawm peb hom khoom raw. Lawv yog cov hlau, steel hlau tsis muaj stainless (stainless acid hlau), thiab tooj sim no peb cov hlau. Vim hais tias ntawm lawv cov yeeb yam sib txawv, cov ntsuas tau los ntawm lawv kuj yuav pom txawv cov yam ntxwv. Tshawb nrhiav txog lawv cov ntaub ntawv raw li muab thiab lwm cov tswv yim rau peb siv, nrhiav tau qhov chaw, thiab qhov teeb meem (Emerson) Thiab kev pheej hmoo raug zoo.
Hauv cov pa hlau, txoj kev faib nyiaj txiag ntau yog ua raws li cov nqi carbon. Lub hom phiaj tseem ceeb ntawm cov kev cai screws yog ua kom cov khoom muaj meej thiab kev ua tiav. Hauv kev siv, feem ntau nws tshwm sim tsis muaj qhov sib ze ntawm cov hniav thiab cov kaus hniav, yog hais tias lub taub hau tawg ntho dhau los, los yog cov hniav tsis nruj kaw, cov xwm txheej tsis tau ntsib. Qhov tseeb ntawm qhov teeb meem zoo. Muaj cov dej nruab nrab, cov pa roj carbon loj, thiab cov hlau carbon ntawm lwm hom, txhua yam nrog lawv cov specifications thiab lub npe. Kev ua lag luam tsis loj heev nyob rau hauv cov nqe lus ntawm kev siv cov high-carbon steels. Yeej, nws yuav tsis raug saws. ntawm.
Tom qab ntawd cov hlau tsis muaj stainless (stainless acid-resistant steel) cov khoom zoo screws, thiab peb txhua tus paub cov khoom khoom ntawm stainless hlau (stainless acid-resistant hlau). 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. Corrosion tsis kam rau kub thiab corrosion, haum lub zog, rau cov txheej txheem welding yog heev lig.
Qhov kawg yog lub hau ntswj ntawm cov khoom siv tooj liab, tsuas yog raws li tooj dag thiab cov ntaub ntawv tshiab tooj hlau (Cov khoom siv). 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.
Tom qab ntawd cov lus saum toj no yog cov khoom siv ntawm cov ntxhuav peb pom niaj hnub no (shì chǎng). Lawv nyias muaj nyias kev siv. Rau peb, peb yuav tsum xaiv ntau yam raws li kev xav tau ntau ntxiv (xuanze). Nws yog kev xaiv ntse
