Stainless hlau ntswj plating plating yog ib qho kev kho deg hauv txoj hauv kev zus ntawm cov ntsia hlau fasteners. Feem ntau, vim li cas lub ntsiab thiab lub hom phiaj ntawm electroplating yog hloov corrosion tsis kam, xeb ua haujlwm thiab zoo li cov xim ntawm cov hlau tsis muaj stainless hlau. Corrosion tsis kam, anti-rust kev ua tau zoo yog qog siv qhov chaw ntawm stainless hlau screws, ua ntsev tsuag tshuaj ntsuam, los txiav txim rau anti-xeb thiab corrosion ntawm cov tsis muaj stainless hlau screws. Ntxiv rau xeb thiab corrosion tsis kam, peb yuav tsum tau txiav txim rau lub plating zoo ntawm stainless hlau screws los ntawm cov nram qab no plaub ntsiab lus:
1, tsos
Thaum cov hlau tsis muaj hlau tsis muaj plated, plated tsis pub kom tsis tshua tsim, hlawv, hnoos, txho, tawv nqaij, khib nyiab, thiab pom tseeb. Pinhole pitting, dub plating, xoob hla, tawg, tsis tuaj yeem tso cai. Thiab mob loj tshaj kos npe.
2, hydrogen brittle
Lub sijhawm ua thiab tuav ntawm cov hlau tsis txhuam, tshwj xeeb tshaj yog thaum lub sij hawm nqa thiab caustic ntxuav ua ntej plating thiab tom qab electroplating, lub nto absorbs atoms hydrogen, thiab cov hlau txheej deposited ces captures hydrogen. Thaum lub khawm nruj nruj, hydrogen yog pauv mus rau feem ntau ntawm cov kev nyuab siab, ua rau lub siab ua kom dhau lub zog ntawm lub hauv paus hlau thiab tsim kom muaj ib qho chaw tawg me ntsis. Hydrogen yog ib qho tshwj xeeb heev thiab ceev nrooj penetrates rau hauv khiv tsim fissures.
3, plating thickness
Kev khiav hauj lwm lub neej ntawm stainless hlau ntsia hlau fasteners nyob rau hauv corrosive atmospheres yog proportional to lub thickness ntawm lo. Qhov kev pom zoo ntawm plating thickness yog 0.00015 rau 0.0005 nyob rau hauv. (4 txog 12 um). Kub dip galvanizing: qhov nruab nrab cov thickness yog 54 um (tus nominal diameter yog ≤ 3/8 yog 43 um), thiab cov thickness 43hm (tus nominal diameter ≤ 3) / 8 yog 37um).
4, txheej faib
Stainless hlau screws siv sib txawv deposition txoj kev, thiab cov coatings yog feeb nyob rau ntawm lub ntawm fasteners. Thaum cov hlau thaiv cov khoom khawm khoom plated, plated hlau tsis zoo li tso rau ntawm ntug peripheral, thiab ib txheej thicker yog tau ntawm lub ces kaum. Nyob rau hauv txoj hlua khawm ntawm lub khawm, cov thickest txheej yog nyob rau ntawm lub khob ntawm cov xov, maj thawm raws sab ntawm cov xov, tso cov thinnest rau hauv qab ntawm tus hniav, thaum kub dip galvanizing yog qhov ntxeev lus xwb, thicker txheej muab tso rau hauv lub ces kaum thiab Hauv qab ntawm xov, tus neeg kho tshuab plating ntawm cov hlau plated nyhav tib yam nkaus li cov cua kub ntses txheej, tab sis yog smoother thiab ntau ntau dua li ntawm tag nrho nto.
