Muaj ntau tus phooj ywg tej zaum yuav xav paub txog kev ua tau zoo ntawm zinc txhuas magnesium steel kav? Niaj hnub no, Yuantai Derun yuav coj koj peb qhov kev sim sib piv los saib leej twg muaj peev xwm tiv thaiv xeb zoo dua li cov kav hlau galvanized.
Ua ntej, cia peb coj koj mus rau qhov xwm txheej sim hnub no. Lub npe ntawm qhov kev sim no hu ua kev sim tshuaj ntsev. Yog li qee tus phooj ywg yuav tau nug, kev sim tshuaj ntsev yog dab tsi? Vim li cas peb thiaj yuav tsum ua qhov kev sim tshuaj ntsev ntawm cov yeeb nkab hlau. Lawv muaj kev cuam tshuam li cas rau cov neeg yuav yeeb nkab hlau?
Qhov kev sim tshuaj tsuag ntsev cuav suav nrog kev sim tshuaj tsuag ntsev nruab nrab, kev sim tshuaj tsuag acetate, kev sim tshuaj tsuag acetate uas nrawm nrog ntsev tooj liab, thiab kev sim tshuaj tsuag ntsev hloov pauv.
Kev sim tshuaj tsuag ntsev nruab nrab (NSS test) yog ib txoj kev sim xeb ceev uas tau tshwm sim thiab tam sim no siv dav hauv ntau qhov chaw. Nws siv 5% sodium chloride saline kua, thiab tus nqi PH ntawm cov tshuaj tau kho rau hauv qhov nruab nrab (6-7) ua cov tshuaj tsuag. Qhov kub ntawm kev sim yog teem rau ntawm 35 ℃, thiab tus nqi ntawm cov tshuaj tsuag ntsev uas xav tau yog 1-2ml / 80cm ². Nruab nrab h. Hnub no peb yuav ua qhov kev sim tshuaj tsuag ntsev nruab nrab no.
Kev sim tshuaj tsuag ntsev tsis muaj zog rau 24 teev yog sib npaug rau 1 xyoos hauv ib puag ncig ntuj
Tom qab 48 teev ntawm kev tsuag ntsev tsis muaj ntsev NSS (ib puag ncig ntuj rau 2 xyoos) rau ntawm cov qauv kuaj:
Tangshan Yuantai Derun Steel Pipe Co., Ltd. Khoom Tshiab Galvanized StripZinc Aluminium Magnesium Square Tube
Kev ntsuas ntawm qhov chaw: Qib 8:
Thaj chaw tsis zoo suav rau 0.15% ~ 0.2%,
Qib tsos B (yuav luag tsis muaj qhov tsaus ntuj los ntawm kev xeb ntawm txheej), nrog rau qhov tsis zoo nkauj me ntsis ntawm qhov chaw ntawm cov qauv;
Cov khoom siv galvanized square tube
Kev ntsuas ntawm qhov chaw: Qib 1:
Thaj chaw muaj qhov tsis zoo yog li ntawm 35% ~ 45%,
Qib tsos I (tawg), thiab cov qauv qhia txog kev xeb ntawm cov hlau puag.
Los ntawm kev sib piv cov kev ntsuam xyuas, cov khoom tshiab ntawm Tangshan Yuantai Derun Steel Pipe Co., Ltd., galvanized stripzinc txhuas magnesium square raj, muaj kev tiv thaiv xeb ib puag ncig zoo dua ligalvanized strip square tube ib txwm muajcov khoom.
