1.Dab tsi yog cov ntsiab cai ntawm kev xaiv?
Xim -coated steel sheets (coated steel plates) yog tsim los ntawm txheej txheej xim xim rau saum npoo ntawm cov khaub thuas- dov galvanized lossis aluminium-zinc coated substrates. Lawv lub ntsiab kom zoo dua yog nyob rau hauv lawv superior corrosion kuj. Cov ntsia hlau siv rau kev sib txuas yuav tsum yog ib feem ntawm kev tiv thaiv corrosion tag nrho, tsis yog qhov txuas tsis muaj zog. Yog tias cov ntsia hlau corrode ua ntej cov ntaub ntawv, nws tuaj yeem ua rau cov xau, xoob kev sib txuas, los yog ua tsis tiav.
2.Dab tsi yog hom screws raug pom zoo?
Qhov zoo tshaj plaws -lub hom phiaj xaiv: Aluminium-zinc plated tus kheej-tapping screws
Nta: Cov ntsia hlau nto muaj qhov sib txawv ntawm cov xim nyiaj dawb snowflake qauv. Nws feem ntau tuaj nrog xim -plastic washer taub hau.
Sab saum toj -tier xaiv: Stainless hlau tus kheej-tapping screws
Nta: Feem ntau stainless hlau hauv nws cov xim ntuj (matte silver-dawb).
Qauv: A2-70 (304 stainless hlau) raug pom zoo. Rau ib puag ncig corrosive heev (xws li cov chaw ntug dej hiav txwv lossis cov nroj tsuag tshuaj), xav txog A4-80 (316 stainless hlau).
Muaj cov kev xaiv: High-zoo galvanized tus kheej-tapping screws
Nta: ci nyiaj los yog xim zinc txheej.
3.Dab tsi yog qhov ua haujlwm ntawm cov khoom siv tseem ceeb?
Waterproof sealing: Thaum lub hau ntsaws ruaj ruaj, lub tshuab ntxhua khaub ncaws deforms, haum nruj rau cov xim ntawm cov xim -coated steel ntawv los tiv thaiv cov dej nag los ntawm cov ntsia hlau qhov.
Cushioning thiab khawb tiv thaiv: Tiv thaiv cov hlau ntsia hlau taub hau los ntawm kev txiav ncaj qha lossis abrading xim -coated nto.
Hluav taws xob rwb thaiv tsev: cais cov hlau sib txawv, txo kev pheej hmoo ntawm electrochemical corrosion.
Kev tshuaj xyuas: Lub tshuab ntxhua khaub ncaws yuav tsum mos, elastic, thiab tiv taus kev laus (tsis yooj yim tawg hauv tshav ntuj).
4.Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev tsim kho?
nruj me ntsis txwv tsis pub sib xyaw: Tsis txhob siv cov pa roj carbon steel zoo tib yam, tus kheej -drilling screws (tsis muaj ntxhua khaub ncaws), lossis cov ntsia hlau yam tsis muaj kev sib khi zoo.
Perpendicular tsav tsheb: Screws yuav tsum tau tsav perpendicular rau lub vaj huam sib luag nto. Tsav tsheb ntawm lub kaum sab xis yuav ua rau lub foob tsis zoo los ntawm cov ntxhua khaub ncaws, inevitably ua rau xau.
Nruab nrab torque: Siv lub tshuab hluav taws xob tshwj xeeb thiab kho lub zog kom haum. Tighten kom txog thaum lub tshuab ntxhua khaub ncaws yog tag nrho flattened thiab bulging me ntsis. Tsis txhob nruj, vim qhov no yuav ua rau cov ntxhua khaub ncaws tawg lossis xim -coated vaj huam sib luag kom deform lossis dent.
Kho qhov chaw:
Ru tsev: Kho ntawm crest ntawm corrugation.
Phab ntsa: Feem ntau kho ntawm lub trough ntawm corrugation.
Cov chaw tshwj xeeb yuav tsum nruj me ntsis ua raws li cov qauv kos duab thiab vaj huam sib luag yam yuav tsum tau ua.
Ntawm - qhov chaw tiv thaiv: Cov ntsia hlau yuav tsum muab cia rau hauv qhov chaw qhuav. Yog tias muaj cov txheej txheem ntxiv ntawm cov ntsia hlau taub hau raug puas tsuaj tom qab kev teeb tsa, nws tuaj yeem kho tau los ntawm kev siv cov xim pleev xim rau kev tiv thaiv corrosion (xws li zinc oxide).
5.Dab tsi yog cov ntsiab lus thiab cov kauj ruam ua?
Saib xyuas tus tsim: Ua ntej, txheeb xyuas cov kev cai tshwj xeeb rau cov fasteners hauv cov duab kos duab lossis cov kev qhia tshwj xeeb.
Sib piv cov ntaub ntawv: Xaiv cov khoom siv ntsia hlau raws li lub substrate ntawm cov xim -coated coil (galvanized steel ntawv GL los yog aluminized zinc ntawv GL) thiab qhov project ib puag ncig (nruab nrab ntug dej hiav txwv, cheeb tsam, industrial inland).
Xam qhov ntev: Txiav txim siab qhov ntev ntawm cov ntsia hlau siv cov qauv "daim ntawv thickness + purlin thickness + 10mm".
Yuav cov khoom tsim nyog: Yuav aluminized zinc tus kheej-tapping screws lossis stainless hlau tus kheej-tapping screws nrog ua tiav EPDM sealing washers los ntawm cov khoom muaj npe nrov thiab tau txais cov ntaub ntawv pov thawj zoo.
Kev tsim kho tus qauv: Muab cov lus qhia rau cov neeg ua haujlwm, hais txog cov ntsiab lus tseem ceeb xws li kev tsav tsheb ntsug thiab kev tswj lub zog.
