Makina opukutira mchenga a Junda Sandblasting ndi makina opukutira utoto a Junda shot peeping ndi zida ziwiri zosiyana. Ngakhale dzinalo ndi lofanana, pali kusiyana kwakukulu pakugwiritsa ntchito. Komabe, kuti tipewe zolakwika zomwe ogwiritsa ntchito amasankha, kusokoneza kugwiritsa ntchito ndikuwononga ndalama, kusiyana komwe kukugwirizana nako kumayambitsidwa pambuyo pake.
1, kusiyana pakati pa kuphulitsa mfuti ndi kuphulitsa mchenga
Mfundo yogwiritsira ntchito kuwombera ndi kupukuta mchenga ndi njira yoyeretsera pamwamba pa chinthucho pogwiritsa ntchito mpweya ngati mphamvu. Kuwombera pogwiritsa ntchito chitsulo chogubuduza, monga chitsulo chogubuduza, mchenga wachitsulo, ndi ceramic shot. Kuphulika kwa mchenga kumagwiritsidwa ntchito ndi zinthu zopanda chitsulo, monga mchenga wa corundum, mchenga wagalasi, mchenga wa resin ndi zina zotero.
2, Kuphulitsa mivi ya Junda ndi njira yophulitsira mchenga
Njira yochotsera zipolopolo ndi kuphulitsa mchenga imadalira zinthu zosiyanasiyana, magwiridwe antchito ndi zofunikira zina kuti mudziwe ngati mungagwiritse ntchito kuphulitsa kapena kuphulitsa mchenga.
3. Kusankha zida zophulitsira ndi kuphulitsa mchenga
Kuchotsa zipolopolo ndi kuphulitsa mchenga kuwonjezera pa kuphulitsa, kuchira kovutitsa, chipangizo chokonzera zinthu zovutitsa ndi chosiyana, zida zina ndi zofanana, ndithudi, tinthu tating'onoting'ono ta zinthu zovutitsa zimathanso kukhala wamba ndipo zida zophulitsa mchenga, ndithudi, zimadalira momwe zinthu zilili.
4. Kuchotsa zipolopolo pogwiritsa ntchito mpweya wopanikizika kapena mphamvu ya makina yozungulira ngati mphamvu ndi kukangana. M'mimba mwake mwa projectile muli pakati pa 0.2-2.5mm, kuthamanga kwa mpweya wopanikizika ndi 0.2-0.6mpa, ndipo ngodya pakati pa jet ndi pamwamba ndi pafupifupi madigiri 30-90. Ma nozzles amapangidwa ndi chitsulo cha T7 kapena T8 ndipo amalimba mpaka kuuma kwa 50-. Moyo wa nozzle iliyonse ndi masiku 15-20. Kuchotsa zipolopolo pogwiritsa ntchito scale, dzimbiri, mchenga woumba ndi filimu yakale ya utoto kuchokera kuzinthu zapakati ndi zazikulu zachitsulo zokhala ndi makulidwe osachepera 2mm kapena zinthu zopangira ndi zopangira zomwe sizifuna kukula kolondola ndi mawonekedwe. Ndi njira yoyeretsera musanaphike pamwamba (plating). Imagwiritsidwa ntchito kwambiri m'malo akuluakulu osungiramo zombo, mafakitale olemera amakina, mafakitale amagalimoto ndi zina zotero. Kuchiza pamwamba pogwiritsa ntchito kuchotsera zipolopolo pogwiritsa ntchito kuchotsera zipolopolo, mphamvu yogwira, zotsatira zoyeretsa ndizodziwikiratu. Koma kuwombera kowonda kwa workpiece yopyapyala kumapangidwa mosavuta, ndipo kuwombera kwachitsulo kumagunda pamwamba pa workpiece (kaya kuphulika kwa mfuti kapena kuphulika kwa mfuti, kuphulika kwa zinthu zachitsulo, chifukwa palibe pulasitiki, kusweka kwa peel, ndi kuphulika kwa filimu yamafuta ndi zinthu zapansi, kotero ndi workpiece yamafuta, kuphulika kwa mfuti, kuphulika kwa mfuti sikungachotse mafuta kwathunthu.
5, kuphulika kwa mchenga ndi njira yotsukira yamakina, koma kuphulika kwa mchenga si kuphulika kwa mfuti, kuphulika kwa mchenga ndi mchenga monga mchenga wa quartz, kuphulika kwa mfuti ndi chitsulo. Mu njira zomwe zilipo zochizira pamwamba pa workpiece, kuyeretsa kwa mchenga ndi zotsatira zoyeretsa. Kuphulika kwa mchenga ndikoyenera kuyeretsa pamwamba pa workpiece ndi zofunikira kwambiri. Komabe, zida zophulitsira mchenga ku China zomwe zilipo pano zimapangidwa makamaka ndi hinge, scraper, bucket elevator ndi makina ena akale onyamula mchenga wolemera. Ogwiritsa ntchito amafunika kumanga dzenje lakuya ndikupanga wosanjikiza wosalowa madzi kuti ayike makina, ndalama zomangira ndizokwera, ndalama zosamalira ndi kukonza ndizokwera. Ndi chisamaliro cha dziko lonse pa kuteteza chilengedwe ndi thanzi la mafakitale, chifukwa njira yophulitsira mchenga ili ndi fumbi lalikulu osati kuipitsa chilengedwe kokha, komanso kosavuta kuyambitsa matenda a ogwira ntchito (silicosis), ili ndi kuphulika kwa mfuti zambiri kuti zilowe m'malo mwa kuphulika kwa mchenga.
Zomwe zili pamwambapa zikunena za kusiyana pakati pa makina ophulitsira mchenga ndi makina opukutira zipolopolo, malinga ndi chiyambi chake, titha kumvetsetsa bwino momwe makinawo amagwiritsidwira ntchito komanso momwe amagwiritsidwira ntchito, kuti tigwiritse ntchito bwino, kuti tikwaniritse zosowa za makinawo.
