Galvanized steel ntawv hlau SGCC
Galvanizing coil steel yog ib hom semi-tiav coil steel ua tiav los ntawm kub dov, pickling passivation lossis kub dov. Tom qab ntxuav thiab quenching, tuab hlau phaj yog infiltrated rau hauv 460 degree zinc tov, coated nrog zinc txheej, thiab ces kub kho, quenched thiab kho los ntawm organic chemistry. SGCC cov ntaub ntawv nyuaj dua li cov khoom siv SECCO, nrog cov yas tsis zoo (kom tiv thaiv kev sib sib zog nqus tsim qauv), zinc txheej tuab thiab tsis zoo malleability.
2. Cov ntawv txias txias SPCC
SPCC yog hais txog qhov txias txias dov ntawm steel castings rau hauv qhov yuav tsum tau nyias thiab tuab kub dov sawb los yog tuab steel phaj los ntawm txias dov zeb. SPCC tsis muaj kev saib xyuas qhov chaw. Thaum raug huab cua, nws yooj yim heev rau oxidized. Tshwj xeeb tshaj yog nyob rau hauv cov dej ntub thiab txias, huab cua oxidation tus nqi accelerates thiab sib sib zog nqus liab xeb tshwm sim. Qhov saum npoo ntawm hlau phaj tsheb chassis plhaub yuav tsum tau txau, plated lossis lwm yam khaws cia thaum lub sijhawm tsim khoom.
3. Galvanized ntawv hlau
Tom qab tshem tawm cov roj, acid pickling thiab passivation, electroplating txheej txheem thiab ntau yam txheej txheem tom qab kev kho mob yog nqa tawm nyob rau hauv lub nruam galvanizing ntau lawm kab, high-precision sheet hlau chassis plhaub dhau los ua phosphatized khoom. SECC tsis tsuas yog muaj cov khoom siv lub cev thiab cov yam ntxwv zoo sib xws ntawm cov ntawv txias txias, tab sis kuj muaj kev tiv thaiv corrosion zoo thiab cov duab kos duab zoo nkauj. Sheet hlau chassis plhaub ua haujlwm yog qhov sib tw heev thiab hloov tau hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab kev lag luam hauv tsev.
4. Stainless hlau hlau SUS301
Cov ntsiab lus chromium tsawg dua SUS304, thiab corrosion kuj tsis zoo. Txawm li cas los xij, tom qab kos duab txias, lub zog tensile zoo dua thiab lub zog tuaj yeem tau txais nyob rau hauv tag nrho cov txheej txheem ntawm tuag casting, thiab nws muaj ductility zoo dua. Nws muaj feem xyuam rau kev saib xyuas lub caij nplooj ntoos hlav phaj, torsion caij nplooj ntoos hlav thiab cuam tshuam teeb liab.
5. Stainless hlau hlau SUS304
Stainless hlau phaj yog cov hlau feem ntau siv. Vim nws cov ntsiab lus npib tsib xee, nws cov corrosion kuj thiab kub kuj zoo dua li manganese hlau. Nrog lub cev zoo, tsis muaj kev kho cua sov txheej txheem nyuaj hauv qab, tsis muaj elasticity.
