Ubwino Wa Pickling Of Stainless Steel Tubes

Pickling pamwamba mankhwala zitsulo zosapanga dzimbiri

Nthawi zambiri pali njira ziwiri za pickling: mankhwala ndi electrolytic. Only mankhwala pickling ntchito dzimbiri chitetezo cha Chitoliro Chachitsulo chosapanga dzimbiris, yomwe imatha kuchotsa sikelo ya oxide, dzimbiri ndi zokutira zakale. Nthawi zina, njira imeneyi angagwiritsidwe ntchito ngati re mankhwala pambuyo kuphulika mchenga. Ngakhale kutsuka kwa mankhwala kumatha kupangitsa kuti pamwamba pakhale paukhondo komanso moyipa, mizere yake ndi yosazama komanso yosavuta kuyipitsa chilengedwe.

Kuchotsa dzimbiri ndi kupopera mbewu mankhwalawa (kupukuta) ndikuyendetsa tsamba la kupopera mbewu mankhwalawa (kupukuta) kuti lizizungulira pa liwiro lalikulu kudzera pagalimoto yamphamvu kwambiri, kuti grit yachitsulo, kuwombera chitsulo, gawo la waya, mchere ndi ma abrasives ena akhoza kupopera (kupukuta) pamwamba pa chitoliro chachitsulo pansi pa mphamvu ya centrifugal. Iwo sangakhoze kokha kuchotsa dzimbiri, oxides ndi dothi, komanso kukwaniritsa chofunika yunifolomu roughness wa zosapanga dzimbiri chitoliro pansi pa zotsatira ndi kukangana kwa abrasive.

Pambuyo pa dzimbiri kuchotsa ndi kupopera mbewu mankhwalawa (kupukuta), osati matupi adsorption wa zitsulo zosapanga dzimbiri chitoliro pamwamba akhoza kukodzedwa, komanso makina adhesion pakati odana dzimbiri ❖ kuyanika ndi chitoliro pamwamba akhoza patsogolo. Choncho, kupopera (kuponya) ndi njira yabwino yochotsera dzimbiri popewa dzimbiri. Nthawi zambiri, kuwomba (mchenga) kumagwiritsidwa ntchito kwambiri pochiza mapaipi amkati, ndipo kuwomba (mchenga) kumagwiritsidwa ntchito pochiza mapaipi akunja. Mavuto angapo ayenera kutsatiridwa pogwiritsira ntchito kupopera (kuponya) kuchotsa dzimbiri
