Kev xaiv cov khoom siv txiv ntoo zoo yuav tsum tau xav txog kev ua haujlwm ntawm ib puag ncig, kev xav tau ntawm kev thauj khoom, kev tiv thaiv corrosion, thiab tus nqi kom ntseeg tau tias muaj kev sib raug zoo thiab kev lag luam.
Siv tau cov xwm txheej thiab xaiv cov lus pom zoo rau cov khoom sib txawv
Carbon Steel Ceev: Lub zog siab thiab tus nqi qis, yog thawj qhov kev xaiv rau niaj hnub kev lag luam sib dhos. Haum rau kev siv tshuab, tsev, lossis rooj tog sib txuas hauv qhov chaw qhuav hauv tsev. Rau kev siv sab nraum zoov, galvanized lossis Dacromet-coated versions raug pom zoo rau kev txhim kho xeb.
Stainless hlau txiv ntseej: siab corrosion kuj, tsis tas yuav tsum tau txheej txheej, haum rau av noo, sab nraum zoov, los yog tshuaj corrosive ib puag ncig.
304 Stainless Hlau: Lub hom phiaj dav dav, tsim nyog rau thaj chaw huab cua dav dav (xws li cov khoom siv ua zaub mov, cov kav dej hauv chav dej).
316 Stainless Hlau: Muaj cov molybdenum, tiv taus cov tshuaj chloride ion corrosion, tsim nyog rau kev tsim khoom hauv hiav txwv, cov chaw ntug hiav txwv, lossis cov khoom siv tshuaj.
Copper (Brass) Txiv Neej: Cov khoom siv hluav taws xob zoo thiab thermal conductivity, corrosion resistant thiab spark -dawb, haum rau tawg- cov ntaub ntawv pov thawj, khoom siv hluav taws xob, lossis cov kav dej. Kuj nquag siv rau kev sib txuas uas yuav tsum tau ntsaws thiab tshem tawm.
Alloy steel txiv ntseej: siab zog thiab siab tawv, haum rau hnyav-load thiab siab- kev ntxhov siab, xws li txuas hniav, khoom siv cua tshuab, thiab cov tshuab hnyav.
Feem ntau siv nrog bolts ntawm qib 10.9 thiab siab dua.
Aluminium thiab aluminium alloy txiv ntseej: Qhov zoo ntawm lub teeb yuag, haum rau qhov hnyav - cov khoom rhiab heev hauv aerospace, cov khoom siv ua kis las, lossis cov khoom siv tsis siv neeg. Txawm li cas los xij, lawv lub zog qis dua, ua rau lawv tsis haum rau siab - thauj khoom sib txuas.
Plastic txiv ntseej: Insulating, corrosion-resistant, thiab lub teeb yuag, haum rau qis- nrawm, qis- cov ntawv thov uas xav tau hluav taws xob rwb thaiv tsev, xws li cov khoom siv hauv tsev thiab cov cuab yeej siv.
Cov Ntsiab Lus Xaiv Cov Ntsiab Lus:
Environmental Priority: Stainless hlau rau huab cua / corrosive ib puag ncig; alloy steel rau siab - kub lossis siab -load puag ncig; tooj liab rau tawg - pov thawj los yog conductive yuav tsum tau.
Matching Bolts: Cov khoom siv ntawm cov txiv ntseej thiab qib yuav tsum sib phim rau lub ntsia liaj qhov rooj kom tsis txhob ua tsis tiav ntxov vim qhov tsis sib xws.
Tus Nqi Ua Lag Luam-offs: Ua ntej tus nqi- cov khoom siv tau zoo thaum ua tau raws li qhov yuav tsum tau ua; Piv txwv li, carbon steel nrog kev kho deg tuaj yeem hloov tag nrho -stainless steel hauv cov ntawv thov zoo tib yam.
