Rau txoj hauv kev los tiv thaiv lub xeb ntawm lub thawv me me 12v dc lub thawv
Kev siv lub 24V DC lub thawv nquag siv yoojyim rau lub sijhawm ntev, thiab xeb ntawm lub thawv yuav ua rau lub cev quab yuam. Rau rooj plaub ntawm xo lub 24V DC lub thawv, raws li cov xyoo dhau los, 6 txoj kev rau kev tiv thaiv lub npov ntawm lub xuab zeb ntawm xeb:
1. Thaum muab ntxuav lub thawv 24V DC, nws tsis tas yuav ntxuav thiab ntxuav. Kev ntxuav yuav tsum tau sib zog mus dhau.
2, qhov zoo tshaj plaws qhov kev haum siab yog siv oxalic acid, kev siv cov concentration 1 ~ 2.
3, pickling kuj siv tau sulfuric acid, pickling lub sij hawm tsis tau ntev heev, qhov zoo tshaj plaws xaiv yog phosphoric acid.
4. Tom qab pickling, nws yog qhov zoo tshaj plaws uas muab cais tawm nrog 1 ~ 2 ntsev carbonate.
5, zinc system phosphating pov tseg acidity yuav tsum siv lub siab txwv, impregnation kev noj tshuaj concentration: TA: 35 lossis ntau tshaj. FA: 1.2AC: 8 (20CC fermentation tube).
6, degreasing yuav tsum siv tsis muaj zog alkaline degreasing, tsis tuaj yeem muaj cov kab mob alkali, TAL yuav tsum raug tswj ntawm ib ncig 15 POINT, PH tsis pub dhau 13.
