Ntau tus phooj ywg yuav xav paub txog kev tiv thaiv corrosion ntawm zinc aluminium magnesium steel kav? Niaj hnub no, Yuantai Derun yuav coj koj peb qhov kev sim sib piv kom pom leej twg muaj peev xwm tiv thaiv corrosion piv rau cov kav dej galvanized zoo tib yam.
Ua ntej, cia peb coj koj los ntawm qhov kev sim niaj hnub no. Lub npe ntawm qhov kev sim no yog hu ua kev sim tshuaj ntsev. Yog li qee tus phooj ywg yuav tau nug, kev sim tshuaj ntsev yog dab tsi? Yog vim li cas peb yuav tsum tau ua ib tug steel yeeb nkab ntsev tsuag kev sim. Lawv cuam tshuam dab tsi rau cov neeg yuav khoom steel?
Qhov kev sim simulated ntsev tsuag tshuaj muaj xws li nruab nrab ntsev tsuag tshuaj ntsuam, acetate spray test, tooj liab ntsev accelerated acetate spray test, thiab alternating ntsev tsuag tshuaj ntsuam.
Neutral ntsev tsuag tshuaj ntsuam (NSS test) yog ib qho kev ntsuam xyuas corrosion nrawm uas tau tshwm sim thiab tam sim no tau siv dav hauv ntau qhov chaw. Nws siv 5% sodium chloride saline tov, thiab cov tshuaj PH nqi yog kho nyob rau hauv nruab nrab ntau yam (6-7) raws li cov tshuaj tsuag. Qhov ntsuas kub yog teem rau ntawm 35 ℃, thiab qhov yuav tsum tau kho tus nqi ntawm ntsev tsuag yog 1-2ml / 80cm ². Nruab nrab h. Niaj hnub no peb yuav ua qhov kev sim tshuaj ntsev nruab nrab.
Neutral ntsev tsuag kuaj rau 24 teev yog sib npaug rau 1 xyoo nyob rau hauv ib puag ncig ntuj
Tom qab 48 teev ntawm nruab nrab ntsev tsuag NSS (natural ib puag ncig rau 2 xyoos) ntawm cov qauv xeem:
Tangshan Yuantai Derun Steel Pipe Co., Ltd. Cov khoom tshiab Galvanized SawbZinc Aluminium Magnesium Square Tube
Surface Rating: Qib 8:
Qhov chaw tsis raug suav nrog 0.15% ~ 0.2%,
Cov tsos mob qib B (yuav luag tsis darkening los ntawm txheej corrosion), nrog me ntsis discoloration ntawm tus qauv;
Common galvanized square tube khoom
Surface Rating: Qib 1:
Qhov chaw tsis raug suav nrog 35% ~ 45%,
Qhov tshwm sim theem I (kev tawg), thiab cov qauv qhia txog kev xeb ntawm cov hlau hauv paus.
Los ntawm kev sib piv, cov khoom tshiab ntawm Tangshan Yuantai Derun Steel Pipe Co., Ltd., galvanized sawbzinc aluminium magnesium square tube, muaj ntau yam zoo ib puag ncig corrosion duazoo tib yam galvanized sawb square rajcov khoom.
