Puas yog qhov loj ntawm cov spangles nyob rau saum npoo ntawm s235jr galvanized cov khoom cuam tshuam rau lawv corrosion tsis kam?
Qhov loj me ntawm cov spangles nyob rau saum npoo ntawm s235jr galvanized khoom (piv txwv li, lub crystalline texture tsim thaum lub qhov kub} dip galvanizing rau lawv corrosion tsis kam. Cov laj thawj tseem ceeb muaj raws li hauv qab no:
1. Kev tsim ntawm cov kab tshaj cum tsis tau txais kev hloov kho lub tshuab tiv thaiv ntawm zinc txheej.
Spangles yog lub ntuj zoo li cov yam ntxwv ntawm kub - dip galvanizing cov txheej txheem ntawm zinc muaju li cov dej txias zinc. Lawv qhov loj me yog txiav txim siab los ntawm tus nqi txias, cov muaj pes tsawg leeg ntawm cov khoom noj uas muaj txhuas (xws li ntxiv ntawm cov ntsiab lus xws li "- los ntawm" kev kho mob).
Txawm hais tias tus kheej loj, tus qauv txheej qauv tseem zoo li qub:
Sab hauv txheej: zinc -} Iron hlau txheej (ze ze rau lub substrate, muab adhesion);
Txheej txheej sab nraud: cov txheej dawb zinc txheej (ua haujlwm ua ib qho kev fij tseg, tiv thaiv cov substrate ntawm electrochemical nkaus).
Kab mob spangles tsuas yog cuam tshuam rau cov npoo microstructure (xws li crystal lis loj) thiab tsis hloov cov tshuaj lom neeg, tuab, lossis hluav taws xob tiv thaiv txheej ntawm zinc txheej. Yog li ntawd, lawv tsis muaj kev cuam tshuam ntau ntawm tag nrho corrosion tsis kam. 2.} Cov tub ntxhais tseem pheej muaj feem cuam tshuam tsis cuam tshuam rau qhov loj me.
Lub corrosion resistance ntawm cov khoom galvanized yog feem ntau txiav txim los ntawm cov hauv qab no, tsis cuam tshuam rau kev me me:
Zinc Txheej Thickness: lub thicker txheej (piv txwv li, z275 yog tuab dua z100), siv cov txheej tiv thaiv ntev dua);
Cov xim txuas ntxiv: Ua kom muaj kev tiv thaiv tau ua tiav yog kom ua tiav los ntawm qhov tsis muaj plating me me thiab pinholes;
Tshaj tawm - kev kho (piv txwv li kev kho mob): piv txwv li passion corrosion ntawm zinc txheej ntawm cov xeb dawb) thiab txhim kho cov huab cua tsis kam;
Kev siv ib puag ncig: cov xwm txheej sab nraud xws li av noo, thiab cov pa paug muaj zog muaj qhov cuam tshuam ntau dua rau kev sib deev.
3. Spangle loj tsuas yog cuam tshuam rau tsos thiab tsis hloov kho kev tiv thaiv kev tiv thaiv.
Spangle Loj thiab Clarity feem ntau cuam tshuam tshwm sim:
Large spangles have a more pronounced surface texture and a more "metallic" appearance, often used in applications where appearance is paramount (eg, unpainted outdoor components);
Me me spangles (lossis ib qho "spangle- free" nto remented los ntawm kev kho kom zoo dua qub) yog smoother thiab ntau haum rau kev pleev xim txuas ntxiv (txo qhov tsis muaj kev pleev xim ntxiv). Txawm hais tias ntawm daim foos sprangle, tsuav yog cov txheej zinc uas yuav tsum ua tiav qhov yuav tsum tau ua kom tuab thiab yog kev tiv thaiv corrosion rau lub substrate.
Tag
Tus spangle loj ntawm s235jr galvanized cov khoom yog qhov pom ntawm cov yam ntxwv zoo nkauj thiab tsis muaj kev cuam tshuam ncaj qha nrog corrosion tsis kam. Kev xaiv yuav tsum ua raws cov tsos uas yuav tsum tau ua (xws li seb puas yog spangle kho kom zoo nkauj yog qhov yuav tsum tau lossis seb cov duab txuas ntxiv yog xav tau). Corrosion Kuj yog feem ntau txiav txim siab los ntawm zinc txheej thickness, txuas ntxiv, thiab tshaj tawm- kho txheej txheem.
