Yintoni i-Phosphate coatings

Iingubo zephosphate zisetyenziselwa ukunyusa ukuxhathisa umhlwa kunye nokuphucula ipeyinti yomgubo ukunamathela, kwaye zisetyenziswa kwiindawo zentsimbi ukuxhathisa umhlwa, ukuthambisa, okanye njengesiseko sokugquma okulandelayo okanye ukupeyinta. Isebenza njengengubo yokuguqula apho isisombululo esidityanisiweyo sephosphoric acid kunye neetyuwa zephosphate sisetyenziswa ngokutshiza okanye ukuntywiliselwa kunye nokusabela ngokwekhemikhali. kunye nomphezulu wenxalenye eqatywe ukwenza umaleko wephosphates enganyibilikiyo, eyicrystalline.Ii-phosphates zokuguqulwa kwephosphates nazo zingasetyenziswa kwi-aluminiyam, i-zinc, i-cadmium, isilivere kunye ne-tin.
Iindidi eziphambili zokugquma i-phosphate yi-manganese, isinyithi kunye ne-zinc.I-phosphates ye-Manganese isetyenziselwa ukuxhathisa ukubola kunye nokuthambisa kwaye isetyenziswe kuphela ngokuntywiliselwa. Iiphosphates zentsimbi zidla ngokusetyenziswa njengesiseko sokwaleka okunye okanye ukupeyinta kwaye zisetyenziswa ngokuntywiliselwa okanye ngokutshiza. IZinc phosphates zisetyenziselwa ukuthintela umhlwa (P&O), umaleko we-lubricant base, nanjengesiseko sepeyinti/yokugquma kwaye ingasetyenziswa ngokuntywiliselwa okanye ukutshiza.
Ukwaleka kwephosphate ngumaleko wenguqu kwisixhenxeral iintlonipho. Ixinene kancinci kunezinye iintsimbi kodwa ixinene ngakumbi kuneetyatyekwe. Ineempawu zokwandiswa kwe-thermal eziphakathi phakathi kwentsimbi kunye nokwaleka. Isiphumo kukuba umaleko we-phosphate unokugudisa utshintsho olukhawulezileyo ekwandiseni ubushushu obunokuthi bubekho phakathi kwesinyithi kunye nepeyinti. Iingubo ze-phosphate zi-porous kwaye zinokufunxa i-coating. Emva kokunyanga, ipeyinti iyaqina, ivalele kwii-phosphate pores. Ukubambelela kuphuculwe kakhulu.

STAGE PHOSPHATE INKQUBO YOKUTSHELA

1. Ukucoca okudibeneyo kunye ne-phosphating. 1.0 ukuya kwi-1.5 imizuzu kwi-100 degrees F ukuya kwi-150 degrees F.
2. Ukuhlamba ngamanzi 1/2 umzuzu
3. I-Chromic acid ihlanjululwe okanye ihlanjululwe ngamanzi adibeneyo. 1/2 umzuzu.
