Cov kauj ruam tseem ceeb hauv tus txheej txheem ntawm capping
Txoj kev kho cua sov yuav ua kom kev ua tau zoo dua qub, cov khoom siv cuab yeej hluav taws xob hauv kev ua lag luam nyob rau hauv txoj haujlwm ntawm qhov chaw yoojyim, Snap Cap thiab steel microstructure tseem yog cov ntau tshaj, yog li ntau txoj kev kho thaum tshav kub kub, kev ua kom lub cev, kev qis, "plaub qhov hluav taws kub", Snap Cap qhov tsab xov xwm no tsuas yog kev tshawb nrhiav qhov kev ua ntawm kev tuav ib daim npav (card-fire).
Raws li tau pom hauv daim duab 1, Snap Cap tiav kev txhim kho yog tseem hu ua kev txhim kho kev lag luam, feem ntau hu ua kev tsis sib haum, uas feem ntau siv los ua kev kho mob thaum kawg rau qee yam tsis muaj kev ua hauj lwm los yog ua ib feem ntawm cov khoom ua haujlwm.
2, pob annealing yog siv rau eutectoid carbon hlau thiab hlau alloy tuam hlau, nws lub hom phiaj tseem ceeb yog kom txo qhov nyuaj, txhim kho txoj haujlwm, thiab rau lub neej yav tom ntej los npaj rau quenching.
3, kom muaj kev ntxhov siab, Snap Cap kuj hu ua kub nthe kub cev, qhov kev siv technology hauv cov txheej txheem ntawm daim card npog kev tiv thaiv yog siv los tua tawm castings, forgings, vuam qhov chaw, Snap Cap qhov kub npau npoo, qhov chaw txias txias thiab lwm cov kev ntxhov siab. Yog tias cov kev nyuab siab no tsis raug tshem tawm, nws yuav ua rau cov hlau tau deform los yog tawg tom qab ib lub sijhawm, lossis thaum lub sijhawm txiav ntxiv. Ib qho ntawm kev ua kom tiav thiab kev sib tw spheroidizing muaj kev txheeb ze, ob qho tib si nyob rau kev siv kaw, Snap Cap inseparable.
Dab tsi yog qhov corrosive zog ntawm lub hau kev tiv thaiv?
Ntau hom hlau tiv thaiv txheej txheem, lub caij nplooj ntoos hlav, qhov dav yog siv cov txheej txheem kub plating kom tau cov hlau tiv thaiv txheej txheem. Electroplated tiv thaiv txheej tsis tsuas tiv thaiv corrosion, Snap Cap, tab sis kuj pab txoj kev pom ntawm lub caij nplooj ntoos hlav. Tej co electroplated hlau kuj tseem tuaj yeem txhim kho kev ua tiav ntawm lub caij nplooj ntoos hlav, xws li kev txhim kho cov tawv tawv, hnyav hnyav ntxiv, txhim kho thermal stability, tiv thaiv kom tawg hluav taws xob. Tab sis yog hais tias tsuas yog rau qhov corrosion ntawm lub cap, tus general yuav tsum siv galvanized txheej thiab electroplated cadmium txheej.
Zinc nyob rau hauv cov cua qhuav ruaj khov, Snap Cap yuav luag tsis hloov, tsis yooj yim hloov xim. Nyob rau hauv cov av huab cua yuav tsim ib txheej ntawm zinc oxide los yog carbon zinc carbonate dawb zaj duab xis. Cov txheej txheem ntawm cov yeeb yaj kiab no tuaj yeem tiv thaiv tau mus ntxiv. Yog li cov txheej hauv seem rau lub caij nplooj ntoos hlav nyob rau hauv dav dav atmospheric mob corrosion tiv thaiv txheej. Qhov twg nrog sulfuric acid, hydrochloric acid, Snap Cap caustic soda thiab lwm txoj hauv kev tiv tauj, thiab nyob rau hauv cov huab cua ntawm sulfur dioxide thiab lwm yam pa cua ua haujlwm nyob rau lub caij nplooj ntoos hlav, tsis haum rau zinc txheej txheem.
Nyob rau hauv dej hiav txwv lossis siab kub cua, thiab nrog dej hiav txwv nyob rau lub caij nplooj ntoos hlav, 70 ℃ dej kub siv nyob rau lub caij nplooj ntoos hlav, cadmium ruaj khov, Snap Cap muaj zog corrosion. Cadmium txheej dua zinc txheej zas thiab zoo nkauj, mos, yas dua zinc zoo, qhov txheej txheem hydrogen embrittlement me me, qhov tsim nyog rau lub caij nplooj ntoos hlav raws li kev tiv thaiv txheej txheem. Tab sis cadmium scarce, Snap Cap kim, thiab cadmium ntsev lom toxicity, qhov muaj kuab paug muaj zog heev. Yog li, kev txwv ntawm kev txwv. SNAP Cap Yog li, feem ntau ntawm cov aviation, navigation thiab electronics kev lag luam tsuas yog siv nyob rau hauv lub cap ntawm cadmium txheej raws li ib tug tiv thaiv txheej.
