Kuphulika kwa Mchenga-Mtundu Umodzi Wa Pamwamba Kumaliza

Kuphulika kwa mchengandi njira yoyeretsera ndi roughening pamwamba pa gawo lapansi ndi zotsatira za kuthamanga kwa mchenga wothamanga kwambiri.mpweya wothinikizidwa ntchito ngati mphamvu kupanga mkulu-liwiro jet mtengo kupopera zipangizo (mkuwa ore, quartz mchenga, emery, chitsulo mchenga, Hainan mchenga) pamwamba pa workpiece kuchitiridwa pa liwiro lapamwamba, kotero kuti maonekedwe. kapena mawonekedwe a kunja kwa workpiece pamwamba kusintha., Chifukwa cha kukhudza ndi kudula zotsatira za abrasive pamwamba pa workpiece, pamwamba pa workpiece akhoza kupeza mlingo wina wa ukhondo ndi roughness osiyana, kuti makina katundu wa workpiece pamwamba ndi bwino, motero kuwongolera kutopa. kukana kwa workpiece, kuonjezera ndi kupaka Kumata pakati pa zigawozo kumatalikitsa kulimba kwa filimu yophimba komanso kumathandizira kukweza ndi kukongoletsa utoto.
The pretreatment stage of thesandblasting ndondomekoamatanthauza mankhwala omwe ayenera kuchitidwa pamwamba pa workpiece pamaso workpiece ndi sprayed ndi kupopera ndi wosanjikiza zoteteza.
Ubwino wa chithandizo chisanadze asandblasting ndondomekozimakhudza kumamatira, mawonekedwe, kukana chinyezi komanso kukana kwa dzimbiri kwa zokutira.Ngati ntchito yokonzekeratu siyikuchitidwa bwino, dzimbiri lidzapitirira kufalikira pansi pa zokutira, zomwe zimapangitsa kuti chovalacho chiwonongeke.Pamwamba pake pamakhala kutsukidwa bwino ndi workpiece yomwe nthawi zambiri imatsukidwa imatha kufananizidwa ndi zokutira ndi njira yowonetsera, ndipo moyo ukhoza kukhala wosiyana nthawi 4-5.Pali njira zambiri zoyeretsera pamwamba, koma njira zovomerezeka kwambiri ndi izi: zosungunulira, pickling, zida zamanja, zida zamagetsi.
