Dry sandblasting vs Wet sandblasting vs Vacuum sandblasting

Kuwombera mchenga pochotsa dzimbiri ndi imodzi mwa njira zapamwamba kwambiri zopangira mankhwala. Izo osati akhoza kwathunthu kuchotsa okusayidi lonse, dzimbiri, akale utoto filimu, mafuta madontho ndi zonyansa zina kuchokera pamwamba zitsulo, kupanga zitsulo pamwamba kusonyeza yunifolomu zitsulo mtundu, komanso angapereke zitsulo pamwamba ena roughness kupeza uniformly akhakula pamwamba. Itha kusinthanso kupsinjika kwamakina kukhala kupsinjika, kuwongolera kumamatira pakati pa anti-corrosion wosanjikiza ndi chitsulo choyambira komanso kukana kwa chitsulo komweko.

Pali mitundu itatu ya mchenga: youmamchengakuphulika, kunyowamchengakuphulitsa ndi vacuummchengakuphulitsa. Kodi mukudziwa ubwino ndi kuipa kwawo?

I.Dry sandblasting:

Ubwino wake:

Kuthamanga kwambiri komanso kuchita bwino, koyenera kuzinthu zazikulu zogwirira ntchito ndi ntchito zomwe zimafuna kuchotsedwa kwa dothi lolemera.

Zoyipa:

Amapanga kuchuluka kwa fumbi ndi zotsalira za abrasive, zomwe zingayambitse kuipitsidwa kwa chilengedwe ndi kusungidwa kwa abrasive. Kusasunthika kwa ma abrasives ndi vuto lofala.I.Kulimbitsa pamwamba:

Kuphulika kwa kuwombera kumapangitsa kuti pakhale kupanikizika kotsalira pamwamba pa zigawo zake ndi kuphulika kothamanga kwambiri, motero kumawonjezera mphamvu ya kutopa ndi kuvala kwa zipangizo.

II.Yonyowamchengakuphulitsa

Ubwino:

Madzi amatha kutsuka zinthu zowononga, kuchepetsa fumbi, kusiya zotsalira pang'ono pamtunda, ndikuletsa kutsika kwa magetsi osasunthika. Ndi oyenera decontamination ndi pamwamba mankhwala a mwatsatanetsatane mbali, kupewa zina kuwonongeka kwa workpiece pamwamba.

Zoyipa:

Liwiro ndi lochedwa kuposa la youmakulima mchenga. Sing'anga yamadzi imatha kuyambitsa dzimbiri ku chogwirira ntchito, ndipo nkhani yakuthira madzi iyenera kuganiziridwa.

III.Kupukuta mchenga

Vacuum sandblasting ndi mtundu wa mchenga wowuma. Ndi njira yeniyeni muukadaulo wowuma mchenga womwe umagwiritsa ntchito machubu a vacuum oyendetsedwa ndi mpweya woponderezedwa kuti apititse patsogolo kupopera mbewu mankhwalawa. Dry sandblasting imagawidwa mu mtundu wa jet air ndi mtundu wa centrifugal. Vacuum sandblasting ndi ya mtundu wa jet ya mpweya ndipo imagwiritsa ntchito mpweya wotuluka kupopera zinthu zowononga pa liwiro lalikulu pamwamba pa chogwirira ntchito. Ndizoyenera makamaka zogwirira ntchito zomwe sizoyenera madzi kapena mankhwala amadzimadzi.

Ubwino:

Zogwiritsira ntchito ndi abrasive zimasindikizidwa kwathunthu mkati mwa bokosi, kuteteza fumbi kuti lisathawe. Malo ogwirira ntchito ndi aukhondo ndipo sipadzakhala tinthu tating'onoting'ono tomwe timawulukira mumlengalenga. Izi ndizoyenera pokonza magawo olondola omwe ali ndi zofunika kwambiri zachilengedwe komanso kulondola kwapamtunda kwa workpiece.

Zoyipa:

Liwiro la opareshoni ndilochepa. Si abwino pokonza workpieces lalikulu ndi zipangizo mtengo ndi mkulu.

Kuti mudziwe zambiri, chonde omasuka kukambirana ndi kampani yathu!
