Kuphulika kwa mchenga ndi njira yonse yochotsa ndi kudutsa pamwamba pa gawo lapansi pogwiritsa ntchito mchenga wothamanga. Mpweya woponderezedwa umagwiritsidwa ntchito ngati mphamvu yoyendetsa kuti ipange mtengo wopopera mofulumira kwambiri kuti upopera msanga zinthu zopopera (mchenga wamkuwa, mchenga wa quartz, mchenga wa golide, mchenga wachitsulo, mchenga wa Hainan Province) pamwamba pa workpiece kuti athetsedwe. , kotero kuti kunja kapena mawonekedwe a workpiece akupanga kusiyana.
Chifukwa cha kukhudza ndi kudula zotsatira za abrasive pamwamba pa workpiece, pamwamba pa workpiece akhoza kupeza mlingo winawake wa ukhondo ndi roughness osiyana pamwamba, kotero kuti ntchito pamwamba pa workpiece ndi bwino, motero kuwongolera kutopa kukana kwa workpiece, ndi kuwongolera ndi ❖ kuyanika. Kumamatira pakati pawo kumawonjezera kulimba kwa zokutira.
Sandblasting ntchito:
(1) Zovuta pamwamba pa chitsulo chosungunula
Kuyeretsa ndi kupukuta kwa workpiece pambuyo pa kutentha kutentha kumatha kuchotsa zinyalala zonse (monga oxide sikelo, madontho amafuta ndi zotsalira zina) pamwamba pa kuponyera mwatsatanetsatane ndi workpiece pambuyo pa chithandizo cha kutentha. ndondomeko, ndi pamwamba pa workpiece akhoza opukutidwa ndi opukutidwa bwino kusalala workpiece. Pamwamba pa workpiece amagawidwa mofanana ndi yunifolomu mtundu woyamba wa alloy, zomwe zimapangitsa kuti pamwamba pa workpiece ikhale yokongola kwambiri.
(2) Machining workpiece burr kuchotsa ndi kukongoletsa pamwamba
Sandblasting akhoza kuchotsa burrs zabwino pamwamba pa workpiece, ndi kupanga pamwamba workpiece lathyathyathya, kuthetsa kuwonongeka kwa burrs.
(3) Kupititsa patsogolo mawonekedwe a ziwalo
Pambuyo pa makina opangidwa ndi mchenga, yunifolomu ndi yaing'ono ya attapulgite imatha kupangidwa pamwamba pa zigawozo, kuti mafuta azitha kusungidwa, potero kuwongolera mulingo wamafuta, kuchepetsa phokoso ndikuwonjezeka. moyo wautumiki wa zida.
(4) Kukongoletsa kwa chopangira china chapadera
Kuwombera mchenga kumatha kuwulula milingo yosiyanasiyana ya gloss. Monga akupera ndi kupukuta zitsulo zosapanga dzimbiri mbale workpieces ndi mapulasitiki, ndi kupukuta yade, mapangidwe kukongoletsa padziko frosted galasi, etc.
