Phosphating kutendeuka machira

Iyo inozivikanwa pre-kurapa kwesimbi substrates nguva isati yashandiswa kupfeka hupfu is phosphating iyo inogona kusiyana mukuremerwa kwekuputira.

Iyo yakakura iyo yekuchinjisa coating uremu ndiyo yakakura dhigirii yekudzivirira kwemarara inowanikwa; iyo yakaderera coating uremu zviri nani michina zvinhu. Saka zvinodikanwa kuti usarudze kuwirirana pakati pema mechanical properties uye kurwisana nekuora. High phosphate coating weights inogona kupa dambudziko nepoda coatings mune iyo kristini kutyoka kunogona kuitika kana iko kupfekedzwa kuri pasi pesimba rinoshandiswa munharaunda, semuenzaniso. kukotama kana kukanganisa.

Nekuda kwekunamira kwakanakisa kwehupfu hwekufukidzira kune phosphate coating, disbandment inowanzoitika pane phosphate / simbi substrate interface kwete pane phosphate / hupfu hwekuputira interface.

Phosphate coatings yakafukidzwa neBS3189/1959, Kirasi C ye zinc phosphate uye Kirasi D yesimbi phosphate.
A fine grain crystalline zinc phosphate inokurudzirwa pakupfekedza huremu hwe1-2g/m2 uye yesimbi phosphate pa 0.3-1g/m2. Kushandiswa kunogona kuitwa nepfapfaidzo kana dip. Chromate passivation haiwanzodikanwa.
Zinc phosphate inogona kupfapfaidza kana dip kuiswa mukuita nhanho shanu, kureva. alkali degrease, sukurudza, zinc phosphate, maresheni maviri emvura.

Iron phosphate coatings inowanzopfapfaidzwa inoiswa mumatanho matatu kana mana. Basa racho rinowanzopfuura nepakati pezvikamu zviviri zvekusuka mvura isati yaoma.
Izvo zvakakosha kuti workpiece mushure me phosphating ipfu yakaputirwa nekukurumidza sezvinobvira mushure mekuoma.
