Hom Phosphate Kab

● Hlau phosphate

Hlau phosphate yog feem ntau siv pretreatment rau hmoov txheej vim nws yuav siv tau nrog yuav luag txhua yam ntaub ntawv thiab muaj ntau environmentally friendly bi-products los yog sludge. Cov txheej txheem no feem ntau yog siv los ntawm cov ntaub ntawv steel.

● Zinc Phosphate

Zinc phosphate yog non-metallic, crystalline txheej uas tsis tshua muaj siab rau cov ntaub ntawv. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov, zinc phosphate tshwm sim los ntawm kev daws nws tus kheej, tsis yog los ntawm qhov chaw zoo li hlau phosphate txheej. Zinc phosphate crystals pib tsim ntawm qhov chaw anodic ntawm qhov chaw nto thiab nres kev sib sau thaum qhov chaw ntawm qhov chaw tau noj, piv txwv li. lawv ntaus lwm tus siv lead ua. Tsis zoo li cov hlau phosphate, zinc phosphate tsis tuaj yeem ntxuav thiab lub tsho tib lub sijhawm: yog li ntawd, plaub theem - ntxuav, yaug, zinc phosphate, yaug yog ib qho kev teeb tsa. Thaum zinc phosphating muab cov txheej txheem adhesion zoo dua, txheej txheej zoo dua nyob rau hauv qhov chaw nruj thiab zoo dua corrosion, cov txheej txheem muaj cov nqi khiav lag luam ntau dua, siv cov hlau hnyav, thiab tuaj yeem tsim cov sludge ntau, tsis muaj ib qho twg yog ib puag ncig zoo rau kev pov tseg. Zinc phosphate feem ntau yog siv rau cov khoom siv hlau galvanized.

● Chromium phosphate

Chromium phosphate feem ntau yog siv rau aluminium alloy raws li qhov chaw. Thaum cov txheej txheem no zoo, zoo li zinc phosphate, nws siv cov hlau hnyav uas yuav tsum tau rov qab los rau kev pov tseg ib puag ncig.

●Phosphate Process Controls

Kev tswj cov txheej txheem phosphating yog qhov tseem ceeb kom ua tiav cov txheej txheem sib xws uas thaum kawg ua rau txheej txheej txheej txheej ruaj khov. Cov txheej txheem tseem ceeb tshaj plaws hauv kev hloov pauv phosphate txheej yog:

Lub sij hawm - lub sij hawm sib cuag ntev dua lub sij hawm ntau rau cov tshuaj tiv thaiv, cov txheej txheem yuav tsum tau ntev txaus kom tso cai rau chemistry los tsim ib txheej txheej.

Kub - chemistry feem ntau ua nruj dua ntawm qhov kub siab

Concentration thiab pH - ntau acid nyob rau hauv concentration accelerates txheej txheej txheej thiab tuaj yeem ua rau hnyav tag nrho cov txheej txheem.
