Ua ntej, yam ntawm kev kho mob nto:
Txoj kev kho qhov thaj chaw yog qhov txheej txheem ntawm kev ua ib txheej txheej rau saum npoo ntawm ib qho workpiece los ntawm ib txoj kev. Lub hom phiaj ntawm cov kev kho mob saum npoo yog muab cov tsos ntawm cov nplaim ntawm cov khoom thiab cov nyhuv ntawm kev tiv thaiv corrosion. Cov kev kho qhov chaw saum npoo txhua yam yog vim muaj cov nram qab no:
1. Electroplating: Ib tug tswvcuab uas siv electroplated yog raus tes rau hauv kev sib tov muaj dej uas muaj hlau txuas rau, thiab ib qho tam sim no kis tau los ntawm qhov kev daws plating kom cov hlau electrlated yog precipitated thiab tso rau tus tswvcuab. Kev plated plaster yog galvanized, tooj liab, tooj npaws, chromium, tooj liab-tooj liab, thiab lwm yam.
Qee zaus hau dub thiab daj (xiav), phosphatized, thiab lwm yam.
2. Kub-dip galvanizing: Qhov no yog ua tiav los ntawm kev sib tw cov hlau qhov chaw hauv cov da dej ntawm zinc ntawm qhov kub li ntawm 510 ° C. Vim li ntawd, cov hlau-zinc alloy nyob rau saum npoo ntawm cov hlau maj mam ua kis tau zinc ntawm sab nraud ntawm cov khoom. Kub dip txhuas plating yog ib txoj kev zoo sib xws.
3. Lub plhaub txhua yam: Feem xyuam cov nplaim ntawm cov khoom los ntawm cov txheej hlau thiab cov txheej txheem txias rau qhov txheej txheem ntawm cov khoom.
Screws
Thib ob, txoj haujlwm ua
(A), galvanized (xiav thiab dawb, ntau npaug, dub)
1. Ua ntej: Thermal degreasing tank (5 tso tsheb hlau luam) - Electrolytic degreasing tank (3 tso tsheb hlau luam) - Derusting tank (4 tso tsheb hlau luam)
2. Electroplating: plating tank (20 tso tsheb hlau luam) (ammonium chloride, zinc oxide, gloss Agent, softener solution).
3. Tom qab ua tiav: Tshem Tuag Dissolving (1 lub tank) - Ntsuab tshuaj tank (1 pob) - (xiav / dawb / multicolor / dub)
(b), dub:
1, kev kho mob ua ntej: thermal degreasing tank (4 tso tsheb hlau luam) - muab lub tank tso (4 tso tsheb hlau luam)
2, plaub hau dub: dub (5 pob) (cartka, sodium nitrite)
3, tom qab ua tiav: anti-xeb roj (1 qhov)
