Pickling:
Malinga ndi ndende, kutentha ndi liwiro, zidulo ntchito kuchotsa iron okusayidi khungu mankhwala, amene amatchedwa pickling.
Phosphating:
Njira yopangira zokutira phosphate pamwamba pazitsulo kudzera pamachitidwe amankhwala ndi electrochemical.Filimu yotembenuza phosphate yopangidwa imatchedwa filimu ya phosphating.
Cholinga: Kupititsa patsogolo zotsutsana ndi dzimbiri komanso zotsutsana ndi dzimbiri pamwamba pa zinthu.Panthawi imodzimodziyo, filimu ya phosphate yomwe imapangidwa ngati chonyamulira chopaka mafuta imakhala ndi zotsatira zabwino ndi mafuta odzola ndipo imachepetsa kugunda kwapakati pazitsulo zotsatiridwa ndi zinthuzo.Limbikitsani kumamatira kwa utoto ndikukonzekera sitepe yotsatira.
Saponification:
Pambuyo workpiece ndi phosphating, ndi stearate ndi nthaka mankwala filimu wosanjikiza mu yankho kumizidwa mu kusamba saponification zimatani kupanga nthaka stearate saponification wosanjikiza.Cholinga: Kupanga saponification wosanjikiza wokhala ndi ma adsorption abwino kwambiri komanso mafuta pamwamba pa zinthuzo, kuti athandizire kupita patsogolo kwaukadaulo wotsatira.
Njira ya pickling dzimbiri ndi sikelo ndiyo njira yomwe imagwiritsidwa ntchito kwambiri m'munda wamafakitale.Cholinga chochotsa dzimbiri ndi sikelo ya oxide chimatheka ndi mawotchi amavula mphamvu ya asidi pa kusungunuka kwa oxide ndi dzimbiri kuti apange mpweya wa haidrojeni.Zomwe zimagwiritsidwa ntchito pa pickling ndi hydrochloric acid, sulfuric acid, ndi phosphoric acid.Asidi wa nitric sagwiritsidwa ntchito kawirikawiri chifukwa amatulutsa mpweya wa nayitrogeni woipa wa nitrogen dioxide pa pickling.Hydrochloric acid pickling ndi yoyenera kugwiritsidwa ntchito pa kutentha kochepa, sayenera kupitirira 45 ℃, iyeneranso kuwonjezera kuchuluka kwa asidi mkodzo woletsa.Liwiro la pickling la sulfuric acid pa kutentha kochepa ndilochedwa kwambiri, ndiloyenera kugwiritsa ntchito kutentha kwapakati, kutentha kwa 50 - 80 ℃, kugwiritsa ntchito ndende ya 10% - 25%.Ubwino wa phosphoric acid pickling ndikuti sichidzatulutsa zotsalira zowononga, zomwe ndi zotetezeka, koma kuipa kwa phosphoric acid ndi mtengo wokwera, kuthamanga kwapang'onopang'ono, kugwiritsa ntchito kwambiri ndende ndi 10% mpaka 40%, ndi kutentha kwapang'onopang'ono. kutentha kwabwino kufika 80 ℃.Mu pickling ndondomeko, ntchito zosakaniza zidulo ndi njira yothandiza kwambiri, monga hydrochloric asidi-sulfuric asidi osakaniza asidi, phosphoric asidi-citric asidi osakaniza asidi.
Mzere wa pickling wopangidwa ndi Wuxi T-control ndi wotsekedwa kwathunthu komanso wodzichitira.Njira yopangira ikuchitika mu thanki yotsekedwa ndipo ili kutali ndi dziko lakunja;asidi omwe amapangidwa amachotsedwa ndi nsanja ya asidi kuti ayeretsedwe;njira yopanga imasiyanitsidwa ndi thanzi la wogwiritsa ntchito Impact;kuwongolera zodziwikiratu, kuchita bwino kwambiri, kutulutsa kwakukulu, makamaka koyenera kutulutsa kwakukulu, kupanga chapakati;kompyuta basi kulamulira magawo ndondomeko, ndondomeko khola kupanga;poyerekeza ndi mzere wam'mbuyo wa pickling phosphating, umachita bwino kwambiri, komanso kwambiri Dziko lapansi limachepetsa kuipitsidwa kwa chilengedwe.
