Oku kubizwa ngokuba kukuchola kusetyenziswa i-hydrofluoric acid kunye nesisombululo se-nitric acid ukuhlamba umphezulu wentsimbi oksayidi oveliswe emva kokunyangwa ngobushushu.Isetyenziswe ekubunjweni kwesisombululo kunye nemilinganiselo yokulinganisa: i-HF (3-8%), i-HNO3 (10-15%), i-H2O (imali eseleyo) xa kusetyenzwa ubushushu besisombululo kwi-40-60 °C.
Inkqubo yokuchola umbhobho wentsimbi:
Coca inkunkuma ekuchithekeni kwe-oyile → Iibhaskithi ezilayishiweyo → Ukususwa kwekhemikhali → Ukucoca amanzi ashushu → Amanzi abandayo Ukucoca → Umhlwa ngemichiza → Uxinzelelo oluphezulu lweenwele zokucocwa kwamanzi → Ukuhamba kwamanzi ukuhlamba → Ukucoca amanzi ashushu → Vuthela → uvavanyo
Inkqubo yokukhetha kufuneka inikele ingqalelo kula manqaku alandelayo:
Inqaku lokuqala:ukwamkelwa koluhlu olungenayo, iinkcukacha, ubuninzi kunye nokuqondisa ukusika umgangatho ukwamkelwa okungafanelekanga kokumisa ikhefu lokuchola kunye nesaziso kwangexesha sesebe lolawulo lomgangatho okanye iworkshop.
Inqaku lesibini:Eyokuqala kukongeza i-asidi ngokuhambelana nexabiso lomlinganiselo wolawulo lomgangatho wevenkile, i-asidi eyongeziweyo kufuneka ihanjiswe ngokulinganayo kwi-tank ye-pickling, kunokuba idibanise inxalenye enye ye-asidi;Emva koko lawula ubungakanani bomthamo womphunga, ukuze kulawulwe ubushushu beentsimbi zeasidi ngokubanzi ukulawula ubushushu be-asidi ukuba bulawuleke kancinci (malunga nama-60 degrees), kwaye akufanelekanga ukulawula ubushushu obuphezulu kakhulu okanye imvakalelo yokubila. iasidi;eseleyo kukuququzelela inkqubo yesayithi ikhadi umbhobho yentsimbi, ukwahlula phakathi inombolo isakhelo ezahlukeneyo, Ngenxa yobukho iintlobo ezahlukeneyo zentsimbi pickling ixesha umahluko.
Inqaku lesithathu:ulawulo lwenkqubo yokukha, kunye nelona nyathelo libalulekileyo.Iimveliso ezahlukeneyo imibhobho yentsimbi kunye nentsimbi egqityiweyo pickling kunye degreasing.NONEumbhobho wentsimbi ogqityiweyo ojingayo kwibhafu ye-asidi yokuchola, ngamaxesha afanelekileyo ukuphakamisa umbhobho wentsimbi ubuyela kwitanki yeasidi, ukuze ube yi-oxidation yomphezulu wombhobho wentsimbi ngaphakathi nangaphandle kwePicchi oku ukususa umbhobho wentsimbi, ngokuthe ngcembe ugungxulwa ngamandla. kunye nejethi zamanzi ezinoxinzelelo oluphezulu lokuhlamba umbhobho, emva koko umbhobho wentsimbi kwiifolda ezijingayo kwi-asidi thambisa ixesha elifanelekileyo imibhobho yentsimbi ejinga kwitanki yeasidi kufuneka ifakwe imizuzu eli-10 kwisinki kwaye emva koko ihlanjululwe kancinci kancinci ngaphakathi nangaphandle. .Umbhobho we-oyile kufuneka ugalelwe kwi-oyile engaphezulu kunye nokuthambisa ikalika, cwilise kwisinki imizuzu eli-10 kwaye emva koko uhlambe umngxuma ongaphakathi wogungxulwa ngesebe;ukuqengqeleka iimveliso ezigqityiweyo kumbhobho we-oyile kwi sinki ukufunxa ixesha elithile qiniseka ukuba umbhobho wentsimbi uphole ngokupheleleyo, umbhobho intsimbi kwibhafu asidi isiqingatha somzuzu, kwaye ke kwi sinki kunye gungxulwa-ngesebe.
Inqaku lesine:inkqubo yokukhetha emva komsebenzi wokuhlola.Kugqitywe uvavanyo lombhobho wensimbi ogqityiweyo ogxininise ngokuyintloko ucoceko lweoksidi kwindawo yangaphakathi nangaphandle yombhobho wentsimbi, ngakumbi ekucocekeni kombhobho wangaphakathi, okona kulungileyo umsonto wokusetyenziswa kwe-DON ngokuhlolwa kwefomula, inani lesampulu kufuneka lingabi ngaphantsi kwe-10%.Kulandelwa ukucinywa kweasidi yokuvavanya umphezulu wentsimbi kunye nokungaphumeleli kokuhlolwa kombala wombhobho wentsimbi kufuneka kuphinde kuchongwe;kude i-oyile umphezulu wombhobho wentsimbi kufuneka kungabikho ukuchitheka kwe-oyile, ingqwalasela eyodwa kufuneka kungabikho ziphelo zombhobho ophumayo weasidi.
