Ukuqhunyiswa kwesantiyinkqubo yokucoca kunye ne-roughening umphezulu we-substrate ngempembelelo yokuhamba kwesanti yesantya esiphezulu.Umoya ocinezelweyo usetyenziswa njengamandla ukwenza umqadi wejethi onesantya esiphezulu ukutshiza izinto (intsimbi yobhedu, isanti yequartz, emery, isanti yentsimbi, isanti yaseHainan) ukuya kumphezulu womsebenzi ukuba uphathwe ngesantya esiphezulu, ukuze ukubonakala. okanye ubume bomphezulu wangaphandle wokutshintsha komphezulu womsebenzi., Ngenxa yempembelelo kunye nesiphumo sokusika i-abrasive ebusweni bomsebenzi, umgangatho we-workpiece unokufumana iqondo elithile lokucoceka kunye nobunzima obuhlukeneyo, ukwenzela ukuba iipropati ze-mechanical workpiece surface ziphuculwe, ngaloo ndlela kuphuculwe ukukhathala. ukuxhathisa i-workpiece, ukwandisa kwayo kunye nokugquma Ukunamathela phakathi kweengqimba kwandisa ukuqina kwefilimu yokugqoka kwaye kuququzelele umgangatho kunye nokuhombisa ipeyinti.
Inqanaba lonyango lwangaphambili lweinkqubo yokuqhunyiswa kwesantiibhekisa kunyango ekufuneka lwenziwe kumphezulu womsebenzi ngaphambi kokuba i-workpiece itshizwe kwaye itshizwe ngoluhlu olukhuselayo.
Umgangatho wonyango lwangaphambili lweinkqubo yokuqhunyiswa kwesantiichaphazela ukunamathela, ukubonakala, ukuxhathisa ukufuma kunye nokuxhatshazwa kwe-corrosion ye-coating.Ukuba umsebenzi owenziwe kwangaphambili awukwenziwanga kakuhle, i-rust iya kuqhubeka isasazeka phantsi kwengubo, ibangele ukuba i-coating ibe yizicucu.Umphezulu oye wacocwa ngononophelo kunye ne-workpiece ecocwa ngokubanzi ngokulula inokuthelekiswa ne-coating ngendlela ye-exposure, kwaye ubomi bunokuba ngamaxesha angama-4-5 ahlukeneyo.Kukho iindlela ezininzi zokucoca umphezulu, kodwa iindlela eziqhelekileyo ezamkelweyo zezi: ukucocwa kwe-solvent, pickling, izixhobo zezandla, izixhobo zombane.
