AZ150 chev

1. Dab tsi yog AZ150 cov khoom?

2. Dab tsi yog DX51D AZ150 cov khoom siv?

Qhov no ua ke ob qho tshwj xeeb txhais tau hauv en 10346:
DX51D: Qhia cov qib steel substrate.
`D`=steel rau kev txias.
`X` {{{= tsis-}} allloy steel (nrog cov cuab yeej siv tshuab).
`51` {{= Yam tsawg kawg yog cov meej meej ib qho ib ncig ntawm 140-300 mpa (cov ntau yam tshwj xeeb yog nyob ntawm tuab).
`D`=Cov chav kawm zoo (ductility rau cov ntawv thov sib sib zog nqus).
AZ150: Qhia txog txheej txheej (ntshiab Zinc Txheej, Kub - poob, tag nrho g / m²).
Lub ntsiab lus: "DX51D AZ150" txhais tau hais tias cov ntawv steel haum rau kev sib sib zog nqus duab / txias rau ob tog ntawm - dip galvanizing.

3. Dab tsi yog qhov sib txawv ntawm AZ100 thiab AZ150?

Qhov sib txawv tsuas yog qhov tsawg kawg nkaus coating loj:
AZ100: Yam tsawg kawg tagnrho cov txheej loj=100 g / m².
AZ150: Yam tsawg kawg nkaus tag nrho cov txheej loj=150 g / m².
Qhov tseem ceeb: AZ150 muab ntau zinc thiab yog li muaj kev tiv thaiv corrosion zoo dua li AZ100. AZ150 feem ntau yog siv nyob rau hauv cov chaw muaj teeb meem ntau qhov uas yuav tsum tau ua haujlwm.

4. Yuav ua li cas tuab yog AZ150 txheej hauv microns?

Cov txheej txheej tuab yog muab tau los ntawm qhov loj (150 g / m² tag nrho) thiab qhov ntom ntawm zinc (7.14 g / cm³).
Yam tsawg kawg nkaus qhov nruab nrab tuab ib sab (raug): kwv yees li 10.00 micring) / 7.14 g /}}}}}}}}} {.5 μm rau ib sab).
Tag nrho cov tsawg kawg nkaus qhov nruab nrab tuab: kwv yees li 21 microns.
Cov ntau npaum li cas: Hauv kev xyaum, qhov tseeb qhov nruab nrab txheej tuab rau AZ150 cov khoom siv feem ntau poob hauv 20 txog 25 microns tag nrho (10-12.5 μm rau ib sab). Qhov tsawg kawg nkaus hauv zos tuab ntawm txhua sab yuav tsawg tshaj li qhov nruab nrab ib sab nqi.

5. Yuav ua li cas xam zinc txheej tuab?

Koj xam qhov nruab nrab tuab raws li txheej txheej huab hwm coj thiab lub ntom ntawm zinc.
Cov Qauv:
`Thickness (microns, μm) =} [Txheej ntawm zinc (g / cm³)]`
Cov kauj ruam:
1. Txheeb xyuas cov txheej txheej txheej loj: Qhov no yog tus lej "AZ" (piv txwv li, 100, 150). Nov yog tag nrho cov pawg rau ob sab.
2. Mass ib sab (xaiv tau tab sis nquag): Faib tag nrho cov pawg los ntawm 2 yog tias koj xav thickness ib sab. (piv txwv li, AZ150: 150 g / m² tag nrho / 2=75 g / m² rau ib sab).
3. Siv ntom ntom: ntom ntawm ntshiab zinc=7.14 grams ib cubic centimeter (g / cm³imimeter
4. Chav hloov pauv: hloov mus rau G / m³ rau kev sib xws nrog M² hauv Mev: 7.14 g /}}, 140,000 g / m³. Hloov pauv, hloov cov microns ncaj qha:
1 micron (μm)=10 с metters (m)
1 g / m² thaj tsam kis tau tshaj 1 m n nroog nrog lub ntom ntom ntawm 7.14 g /}} g / m³)=1.4 m 10⁻⁷ m.
Hloov meters rau micrron: 1.4 x 10⁻⁷ m * 1,000,000 μm / m {{5} μm ib g / m² rau ib sab.
5. Xam:
Tag nrho cov theem nrab tuab (μm) =} tag nrho cov txheej loj (g / m²) x 0.14
Qhov nruab nrab thickness ib sab (μm)=(tag nrho txheej txheej loj (g / m²) / 2}}}}}
Piv txwv:
AZ150 Tag Nrho Thickness: 150 G / M² * 0.14 μm / (G / M²) {3} μm
AZ150 rau ib sab tuab: (150 g / m² / 2) * 0.14} {} {} μm / (g / m²) {8 μm
AZ100 Tag Nrho Thickness: 100 g / m² * 0.14=14 μm
AZ100 rau ib sab tuab: 100 g / m² * 0.07=7 μm
