Mefuta ea Phekolo ea Phosphate bakeng sa Phofo ea Phofo

Mefuta ea phekolo ea Phosphate bakeng sa ho apara ka phofo

phosphate ea tšepe

Kalafo e nang le phosphate ea tšepe (hangata e bitsoang thin layer phosphating) e fana ka thepa e ntle haholo ea ho khomarela 'me ha e na liphello tse mpe mekhoeng ea mechine ea ho roala phofo. Iron phosphate e fana ka tšireletso e ntle ea kutu bakeng sa ho pepeseha maemong a tlase le a mahareng a kutu, leha e ke ke ea qothisana lehlokoa le zinc phosphate ntlheng ena. Iron phosphate e ka sebelisoa ho fafatsa kapa ho qoelisa. Palo ea mehato ts'ebetsong e ka fapana ho tloha ho 2-7, ho itšetlehile ka basemetal le tlhokahalo ea tšireletso. Mabapi le kalafo ea zinki phosphate, ts'ebetso ea tšepe ea phosphate ke liphatsa tsa lefutsorally e theko e tlase ebile e bonolo ho e fihlela Lera la phosphate hangata le boima lipakeng tsa 0.3-1.0g/m2.

Zinc phosphate

Ts'ebetso ea zinc phosphate e beha moalo o motenya ho feta oa iron phosphating, 'me e ts'oaretsoe ka mokhoa o sireletsehileng motheong. Zinc phosphate e boetse e na le thepa e ntle haholo ea ho khomarela, le hoja maemong a mang e ka fokotsa botšepehi ba mochine (ho feto-fetoha ha tsamaiso. Zinc phosphate e fana ka tšireletso e babatsehang ea ho senya 'me e buelloa bakeng sa phekolo ea pele ea tšepe le litšepe bakeng sa ho pepeseha lihlopheng tse phahameng tsa kutu. Zinc phosphate e ka sebelisoa sebakeng sa spray kapa dip Dip Palo ea mehato ea ts'ebetso e fapana pakeng tsa 4-8.
Zinc phosphating hangata e theko e boima ho feta iron phosphating, ka lebaka la litšenyehelo tse phahameng tsa semela le ts'ebetso e theko e boima haholo.

Chromate

Letoto la litsamaiso tse fapaneng li fumaneha ka har'a sehlopha sa chromate sa kalafo. Tsamaiso e khethiloeng e itšetlehile ka mofuta oa tšepe kapa alloy, mofuta oa ntho (mokhoa oa ho etsa: casr, extruded joalo-joalo) le ho hlakile, litlhoko tsa boleng.
Kalafo ea Chromate e ka aroloa ka likarolo tse latelang:

Mokhoa oa ho qetela ke mokhoa o atileng haholo oa ho phekola pele ho ho roala phofo. Palo ea mehato ts'ebetsong e ka fapana, ho latela hore na thepa e lokela ho lokisoa hakae bakeng sa chromating, mohlala ka pickling, neut.ralization joalo-joalo le mehato e latelang ea ho hlatsoa.
