Cov khoom siv zoo zoo ntawm lub plhaub yuav tsum tau ua los ntawm cov khoom zoo hickory zoo li cov khoom siv raw, uas yog crushed, polished, steamed thiab ntxuav, kho nrog tshuaj thiab ua tiav los ntawm ntau yam kev tshuaj ntsuam.Walnut plhaub abrasive tsis yog tsuas yog hnav-resistant thiab siab-resistant, tab sis kuj tsis yaj nyob rau hauv acidic thiab alkaline dej, muaj zog av interception muaj peev xwm thiab ceev ceev pom.Walnut plhaub abrasives tom qab cov txheej txheem tshwj xeeb (kom tshem tawm nws cov xim, roj, roj, hluav taws xob them ion huv), kom cov txiv hmab txiv ntoo plhaub abrasives hauv kev kho dej muaj cov roj zoo tshem tawm, ntxiv rau cov khoom siv, yooj yim rau rov qab thiab lwm yam kev ua tau zoo heev, tuaj yeem siv rau hauv cov roj av oily dej phwj kho.Yog li dab tsi yog cov yam ntxwv thiab kev siv ntawm cov khoom zoo walnut plhaub abrasives?
Walnut plhaub abrasiveyog lub cim tshiab ntawm abrasive los hloov quartz xuab zeb abrasive, txhim kho cov dej zoo thiab txo cov nqi kho dej.Nws muaj qhov muaj zog tiv taus siab.Raws li cov ntaub ntawv tau los ntawm cov kev ntsuam xyuas cuam tshuam, qhov nruab nrab compressive txwv ntawm walnut plhaub nplej nrog ib tug particle loj ntawm 1.2-1.6 hli yog 0.2295KN (23.40kgf).Qhov nruab nrab compressive txwv yog 0.165KN (16.84kgf) rau walnut plhaub nplej ntawm 0.8-1.0mm txoj kab uas hla.Nyob rau tib lub sijhawm, cov khoom siv tshuaj ntawm walnut plhaub abrasives yog qhov ruaj khov thiab tsis muaj tshuaj lom, solubility hauv acid, alkali thiab dej me me, qhov poob ntawm walnut plhaub hauv hydrochloric acid yog 4.99% thiab hauv sodium hydroxide. daws yog 3.8%, uas tsis ua rau cov dej tsis zoo.
Ntawm qhov tod tes, walnut plhaub raws li lim xov xwm muaj peev xwm ntawm cov xov xwm lim dej zoo tib yam kom khaws cov khoom tshem tawm hauv cov dej khib nyiab;Ntawm qhov tod tes, walnut plhaub lim xov xwm tuaj yeem tso siab rau nws qhov tshwj xeeb saum npoo physicochemical kom tshem tawm cov roj emulsified hauv cov roj rov qab cov dej khib nyiab los ntawm adsorbing lawv rau ntawm qhov chaw lim xov xwm lossis ntawm coalescence ntawm qhov chaw lim tawm.
Kev siv walnut plhaub ua ib qho adsorbent tau raug tshawb fawb pov thawj.Txawm li cas los xij, qhov viscosity thiab qhov nro ntawm cov roj loj inversely cuam tshuam tus nqi adsorption ntawm walnut shells, thiab rov qab cov roj los ntawm walnut shells yog ntau dua los ntawm lwm yam aqueous media, thiab tuaj yeem ua tiav los ntawm kev quab yuam compression nkaus xwb.Nyob rau tib lub sijhawm, walnut plhaub lim xov xwm tsim nyog rau kev pom zoo ntawm cov dej khib nyiab tom qab pretreatment.
