Galvanized Steel Coil Txheej Thickness
Siv cov kev sib raug zoo hauv qab no los kwv yees lub thickness ntawm txheej txheej txheej hnyav [mass]:
1.00 oz / ft2 txheej hnyav = 1.68 mils txheej thickness,
7.14 g / m2 txheej loj = 1.00 µm txheej thickness.
Siv cov kev sib raug zoo hauv qab no los hloov cov txheej hnyav rau txheej txheej:

Cov txheej txheem txheej txheem yog lo lus uas qhov tsawg kawg peb zaug qhov chaw, tag nrho ob sab txheej txheej hnyav [mas] tau teev tseg.Vim tias muaj ntau qhov sib txawv thiab cov kev hloov pauv uas yog cov yam ntxwv ntawm cov kab kub-dip txheej txuas ntxiv, zinc lossis zinc-hlau alloy txheej tsis yog ib txwm sib npaug ntawm ob qhov chaw ntawm daim ntawv coated;tsis yog nws ib txwm sib npaug ntawm ntug mus rau ntug.Txawm li cas los xij, qhov tsawg kawg yog triple-spot nruab nrab txheej hnyav (hnyav) ntawm ib sab yuav tsum tsis pub tsawg dua 40% ntawm qhov yuav tsum tau ua.
Raws li nws yog qhov tseeb tsim los ntawm atmospheric corrosion kuj ntawm zinc los yog zinc-hlau alloy-coated ntawv cov khoom yog ib tug ncaj qha ua hauj lwm ntawm txheej thickness (qhov hnyav (hnyav)), xaiv ntawm thinner (sib zog) txheej designations yuav ua rau yuav luag linearly. txo corrosion kev ua tau zoo ntawm txheej.Piv txwv li, cov coatings hnyav dua galvanized ua tau txaus nyob rau hauv lub ntsej muag atmospheric raug thaum lub sib zog coatings feem ntau ntxiv coated nrog cov xim los yog ib tug zoo xws li txheej txheej rau corrosion kuj.Vim tias qhov kev sib raug zoo no, cov khoom nqa cov lus "ua tau raws li ASTM A653 / A653Mrequirements" yuav tsum tau qhia txog cov txheej txheem tshwj xeeb.
Tsis muaj qhov tsawg kawg nkaus txhais tau hais tias tsis muaj qhov tsim nyog yam tsawg kawg nkaus rau kev xeem triple- thiab ib qho chaw xeem.
