Dab tsi yog cov tshuaj nquag siv hauv phosphating khoom?
Tso lus
Cov tshuaj nquag siv hauv cov khoom siv phosphating yog:
1. Acid phosphating kua:
· Cov khoom tseem ceeb yog cov tshuaj acidic xws li phosphoric acid thiab nitric acid
· Ib hom phosphating zaj duab xis tuaj yeem tsim rau ntawm qhov chaw hlau
· Haum rau carbon steel, tsis tshua muaj hlau alloy thiab lwm yam substrates
2. Alkaline phosphating kua:
· Cov khoom tseem ceeb yog phosphate, alkali hlau, thiab lwm yam
· Nws tuaj yeem tsim cov phosphating zaj duab xis tuab
· Tsim nyog rau refractory phosphating substrates xws li stainless hlau thiab txhuas alloy
3. Additives:
· Xws li tus neeg sawv cev ntub dej, dispersant, corrosion inhibitor, thiab lwm yam
· Nws tuaj yeem txhim kho qhov adhesion thiab uniformity ntawm phosphating zaj duab xis
· Txhim kho cov nyhuv phosphating thiab kho kom zoo
4. Cov tshuaj ntxuav tu:
· Siv rau pretreatment ntawm substrate xws li degreasing thiab pickling ua ntej phosphating
· Xyuas kom meej tias qhov chaw ntawm lub substrate yog huv si thiab haum rau phosphating tom ntej
5. Passivation daws:
· Passivation ntawm phosphating zaj duab xis tom qab phosphating
· Txhim kho corrosion kuj thiab txhim kho kev pab cuam lub neej
Kev tsim thiab siv cov concentration ntawm cov tshuaj no yuav tsum tau txiav txim siab raws li hom substrate tshwj xeeb thiab cov txheej txheem yuav tsum tau ua. Nyob rau tib lub sijhawm, kev tiv thaiv kev nyab xeeb kuj tseem yuav tsum tau zam kom tsis txhob muaj tshuaj lom neeg xws li kua qaub thiab alkali rau cov neeg ua haujlwm thiab ib puag ncig.
