I. Yuav ua li cas tiv thaiv xeb ntawmStainless hlau tus kheej -Tapping Screws
Kev xeb ntawm stainless hlau tus kheej -tapping screws yog ib qho teeb meem tshwm sim. Cov neeg siv tuaj yeem ua raws li cov kev ntsuas hauv qab no kom txo cov xeb thiab ua kom lawv lub neej ua haujlwm ntev.
Ua ntej, xyuam xim rau cov txheej txheem electroplating. Nws raug nquahu kom xaiv cov xim electroplating nrog lub sij hawm ntev ntsev tsuag tshuaj los txhim kho qhov yooj yim corrosion kuj. Thaum lub sij hawm electroplating txheej txheem, nws yog ib qhov tsim nyog los xyuas kom meej tias qhov saum npoo ntawm screws yog qhuav kiag li. Yog tias txheej txheej electroplating nyias dhau lawm, qhov kev tiv thaiv corrosion yuav txo qis, uas yuav ua rau xeb. Tsis tas li ntawd, cov tshuaj tiv thaiv - xeb tuaj yeem txau tom qab electroplating los txhim kho cov nyhuv anti- xeb ntxiv.
Thib ob, standardize lub cia thiab kev pab cuam ib puag ncig. Tsis txhob tso stainless hlau tus kheej -tapping screws ncaj qha rau hauv av; lawv yuav tsum tau muab tso rau ntawm pallets lossis txee kom tiv thaiv kev sib cuag nrog av noo. Qhov chaw khaws cia yuav tsum ua kom zoo-ventilated kom tsis txhob dampness thiab txo qhov yaig ntawm cov dej vapor hauv huab cua ntawm cov ntsia hlau. Yog tias khaws cia lossis siv nyob rau hauv ib puag ncig uas muaj salinity siab, acidity, alkalinity, kub thiab av noo ntev ntev, cov screws yuav inevitably xeb. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas cov ntsia hlau thiab hloov lawv raws sijhawm yog tias pom muaj xeb.
II. Yuav ua li cas kho nto ntawmTus kheej -Tapping Screws
Kev kho deg ntawm tus kheej -tapping screws yog txheej txheem tseem ceeb los xyuas kom meej tias lawv cov xeb tsis kam, zoo li qub thiab kev pabcuam lub neej. Feem ntau muaj 6 txoj kev kho saum npoo av raws li hauv qab no:
1. Electroplating: Raus tus kheej -tapping screws yuav tsum electroplated raws li cathode nyob rau hauv ib tug electrolyte uas muaj hlau cations ntawm lub hom phiaj electroplating hlau. Los ntawm electrolysis, hlau ions ua raws li qhov chaw ntawm cov ntsia hlau los tsim ib txheej txheej. Cov hlau electroplating muaj xws li npib tsib xee, chromium, tin, tooj liab, kub, nyiaj, thiab lwm yam, uas tuaj yeem xaiv raws li kev xav tau.
2. Anodizing: Use chemical or electrochemical methods to form a dense film layer containing the metal component on the metal surface, enhancing surface hardness and corrosion resistance. Yuav luag txhua cov ntaub ntawv hlau tuaj yeem ua anodized hauv cov khoom siv electrolyte, xws li stainless hlau, zinc alloy, aluminium alloy, tooj liab alloy thiab titanium alloy.
3. Blackening: Feem ntau, alkaline tshuaj oxidation yog saws los ua ib tug dub oxide zaj duab xis rau saum npoo ntawm screws. Vim muaj kev tiv thaiv kev ua haujlwm tsawg ntawm cov yeeb yaj kiab oxide no, nws tsuas yog tsim nyog rau qhov chaw ib puag ncig, oily media, lossis cov xwm txheej nrog cov kev xav tau tshwj xeeb (xav tau lub ntsej muag dub).
4. Passivation: Dissolve hlau cov kab mob nyob rau saum npoo ntawm screws los ntawm kev kho tshuaj, thiab tsim ib tug ntom passivation tiv thaiv zaj duab xis rau saum npoo kom zoo tiv thaiv cov ntsia hlau los ntawm corrosion. Txoj kev kho saum npoo no feem ntau yog siv rau tus kheej -tapping screws rau cov khoom siv hluav taws xob, uas tuaj yeem ua tau raws li kev tiv thaiv corrosion thiab kev huv huv ntawm cov khoom siv hluav taws xob.
5. Electrophoresis: Siv lub hauv paus ntsiab lus ntawm electrophoresis los npog cov khoom xws li xim thiab roj hmab rau ntawm qhov chaw.ntsia hlau fasteners. Tom qab kev kho electrophoresis, txheej txheej ntawm tus kheej -tapping screws yog zoo ib yam, tiaj tus thiab du, nrog kev tiv thaiv zoo thiab zoo nkauj zoo nkauj.
6. Dacromet nto kho: Nws tuaj yeem plated hauv peb xim: dub, nyiaj grey thiab nyiaj dawb. Nws lub ntsiab kom zoo dua yog xeb kuj zoo heev, thiab cov ntaub ntawv siv feem ntau yog carbon steel thiab stainless hlau, tshwj xeeb tshaj yog haum rau tus kheej -tapping screws siv nyob rau hauv hnyav corrosive ib puag ncig.
Nws yuav tsum raug sau tseg tias muaj ntau txoj kev kho saum npoo rau tus kheej -tapping screws. Rau stainless hlau tus kheej -tapping screws, txoj kev kho saum npoo uas tsim nyog yuav tsum raug xaiv raws li cov kev pabcuam tshwj xeeb, kev tiv thaiv corrosion thiab cov kev xav tau zoo. Raws li kev nkag siab zoo ntawm cov khoom siv thiab cov xwm txheej ntawm tus kheej -tapping screws, cov neeg siv tuaj yeem xaiv qhov tsim nyog, uas tuaj yeem tsis tsuas yog ua kom lub ntsej muag zoo thiab zoo ntawm cov ntsia hlau, tab sis kuj tseem siv tau lawv lub neej kev pab cuam.
