Nrog txoj kev loj hlob ntawm tib neeg, tib neeg txoj kev xav tau nce siab dua. Precision stamping davhlau ya nyob twg manufacturers yuav tsum tau xav txog ntau yam thaum tsim stamping qhov chaw. Feem ntau, nws yog ib qho tsim nyog yuav tsum paub txog cov khoom siv tshuaj lom neeg ntawm cov khoom siv raw siv hauv kev tsim cov hlau stamping qhov chaw. Qee lub tuam txhab hlau stamping tsis muaj qhov cuam tshuam yuav xav tias poob thaum lawv thawj zaug sib cuag. Tom ntej no, precision stamping davhlau ya nyob twg manufacturers txheeb xyuas qee cov khoom siv tshuaj ntawm cov khoom siv raw ntawm cov hlau stamping qhov chaw.
Cov khoom siv tshuaj lom neeg ntawm cov khoom siv hlau xa mus rau cov khoom uas tuaj yeem pom tau tsuas yog thaum muaj tshuaj lom neeg tshwm sim, suav nrog oxidation tsis kam, corrosion kuj thiab tshuaj stability.
1. Cov khoom siv tshuaj
Cov khoom siv tshuaj lom neeg ntawm cov ntaub ntawv hlau xa mus rau lub peev xwm ntawm cov ntaub ntawv hlau los tiv thaiv cov tshuaj corrosion los ntawm ntau yam corrosive media ntawm chav tsev kub lossis kub. Nws feem ntau suav nrog corrosion kuj thiab oxidation kuj.
2. Tshuaj corrosion
Qhov no yog qhov tshwm sim ntawm cov tshuaj lom neeg ncaj qha ntawm cov hlau thiab qhov nruab nrab ib puag ncig. Nws suav nrog cov roj corrosion thiab hlau corrosion hauv cov tshuaj tsis yog electrolytic corrosion. Nws cov yam ntxwv yog: cov txheej txheem corrosion tsis tsim tam sim no, thiab cov khoom siv corrosion yog tso rau ntawm cov hlau nto.
3. Electrochemical corrosion corrosion
Corrosion tshwm sim los ntawm kev ua ntawm hlau thiab electrolyte tov (xws li kua qaub, alkali, ntsev, thiab lwm yam) yog hu ua electrochemical corrosion. Nws yog tus cwj pwm los ntawm kev tsim hluav taws xob tam sim no thaum lub sijhawm ua haujlwm corrosion. Cov khoom siv corrosion (xeb) tsis npog qhov chaw ntawm cov hlau anode, tab sis khaws ib qho kev ncua deb ntawm cov hlau anode.
4. General corrosion
Qhov kev xeb no sib npaug ntawm cov hlau sab hauv thiab sab nrauv, kom cov ntu ntu ntu txuas ntxiv txo qis, thiab tom qab ntawd qhov kev ntxhov siab raug rhuav tshem.
5. Intergranular corrosion
Qhov kev xeb no tshwm sim hauv cov hlau raws cov npoo ntawm cov nplej, feem ntau tsis ua rau muaj kev hloov pauv ntawm cov hlau, thiab feem ntau ua rau muaj kev puas tsuaj rau cov khoom siv lossis tshuab.
6. Antioxidant zog
Lub peev xwm ntawm cov ntaub ntawv hlau los tiv thaiv oxidation ntawm chav tsev kub lossis kub. Cov txheej txheem oxidation ntawm cov hlau yog qhov tseeb ntawm cov tshuaj corrosion. Nws tuaj yeem siv ncaj qha rau qhov loj me ntawm qhov hnyav poob ntawm cov hlau nto tom qab corrosion nyob rau hauv ib lub sij hawm ntawm lub sij hawm, uas yog, tus nqi ntawm cov hlau poob.
