1.Dab tsi yog qhov cuam tshuam ntawm lub cev puas tsuaj rau lub galvanized txheej?
Cov txheej txheem crimping cuam tshuam nrog cov yas deformation hnyav. Thaum lub sijhawm txheej txheem no, zinc txheej ntawm qhov chaw yog ncab, nyem, thiab rubbed, uas tuaj yeem ua rau microcracks, flaking, lossis tev.
Ib tug tiav sealing nto yuav tsum tau continuation thiab ceev. Cov teeb meem me me no tuaj yeem cuam tshuam ncaj qha rau kev ncaj ncees ntawm lub sealing nto thiab tsim cov pa me me.
2.Dab tsi yog qhov cuam tshuam ntawm qhov tsis sib xws ntawm qhov tawv thiab hnav tsis kam?
Zinc txheej yog qhov muag muag, tab sis nws muaj qhov sib txawv ntawm cov khoom siv hauv paus. Ntawm qhov compression nto ntawm crimp foob, lub softer zinc txheej yuav hnav los yog hloov, ua rau sealing siab hloov thiab to.
3.Dab tsi yog qhov txaus ntshai ntawm cov tshuaj corrosion?
Yog hais tias lub sealing nruab nrab yog acidic los yog alkaline, nws yuav chemically react nrog zinc, corroding lub sealing nto thiab accelerating foob tsis ua hauj lwm.
Txawm hais tias qhov nruab nrab sealing yog dej los yog cua, zinc yuav oxidize (ua dawb xeb) nyob rau lub sij hawm, thiab cov khoom tshwm sim yuav nthuav nyob rau hauv ntim, muaj peev xwm cuam tshuam qhov nruj ntawm sealing interface.
4.Thaum twg koj yuav "yuav" pom galvanized kauj siv rau kev sib khi?
Hauv qee daim ntawv thov kev sib khi zoo li qub nrog cov kev xav tau tsawg, tsis yog - cov kev xav tau tseem ceeb, thiab ib puag ncig qhuav, galvanized coil hems yuav raug siv rau cov laj thawj nqi. Piv txwv li:
Tsawg- nqi lub cuab yeej thiab lub thawv ntsuas ntsuas npog.
Ordinary txee los tiv thaiv ingress ntawm cov plua plav loj.
Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias cov qauv no feem ntau muab qhov "shielding" muaj nuj nqi, tsis yog qhov tseeb "foob." Nws tsis zoo tiv thaiv cov dej nkag, siab, lossis hmoov av zoo.
5.Dab tsi yog cov ntaub ntawv pom zoo rau crimp seals?
Stainless hlau - Feem ntau thiab kev xaiv zoo tshaj plaws
304/304L Stainless Hlau: Muaj kev tiv thaiv corrosion zoo heev, kev tsim, thiab lub zog, ua rau nws xaiv zoo tshaj plaws rau cov khoom noj, tshuaj, tshuaj, thiab kev lag luam.
316/316L Stainless Hlau: Muaj cov molybdenum, muab cov tshuaj chloride corrosion kuj thiab haum rau marine thiab hnyav kev lag luam ib puag ncig.
Qhov zoo: Nto hardness, ntom, corrosion kuj, thiab ruaj khov kev ua tau zoo, tso cai rau machining los tsim ib tug heev tiaj tus thiab du sealing nto.
Aluminium Alloy
Kev kho anodic oxidation feem ntau yuav tsum tau ua kom muaj zog, hnav-resistant, thiab corrosion{1}}resistant oxide zaj duab xis. Cov yeeb yaj kiab no ua haujlwm zoo tshaj plaws sealing nto.
Qhov zoo: Lub teeb yuag, muaj zog, thiab nrog kev kho kom zoo, muab kev sib khi zoo heev.
Carbon Steel + Plating lossis Txheej
Yog tias cov pa roj carbon steel yuav tsum tau siv rau lub zog lossis tus nqi vim li cas, xav txog kev kho kom zoo dua tom qab crimping.
Hard chrome plating: Qhov saum npoo yog qhov nyuaj heev, du, hnav-resistant, thiab corrosion{1}}resistant, ua rau nws zoo heev sealing nto.
Lwm cov txheej txheem kev lag luam, xws li Teflon (PTFE), muab kev tiv thaiv corrosion thiab qib ntawm elasticity, pab kev sib khi.
