Tasirin taimakon tace diatomite

Tasirin tacewa na taimakon tace diatomite ana aiwatar da shi ta hanyar ayyuka uku masu zuwa:

1.Sieving sakamako

Wannan tasirin tacewa ne. Lokacin da ruwa ke gudana ta cikin ƙasan diatomaceous, ramukan ƙasan diatomaceous sun fi ƙanƙanta girman barbashi na ƙazanta, ta yadda ɓangarorin najasa ba za su iya wucewa ba kuma suna kama su. Ana kiran wannan tasirin sieving. A haƙiƙa, ana iya ɗaukar saman kek ɗin tace a matsayin saman sikeli tare da matsakaicin matsakaicin pore daidai. Lokacin da diamita na ƙaƙƙarfan ɓangarorin bai kasance ƙasa da (ko ɗan ƙasa da ƙasa) diamita na pores na diatomite ba, ƙaƙƙarfan ɓangarorin za su "za a cire su daga dakatarwa". Ware waje, kunna aikin tacewa saman.
2. Tasiri mai zurfi

Tasiri mai zurfi shine tasirin riƙewa na zurfin tacewa. A cikin zurfin tacewa, tsarin rabuwa yana faruwa ne kawai a cikin "ciki" na matsakaici. Wani ɓangarorin ƙazamin ƙazanta waɗanda ke ratsa saman kek ɗin tace suna toshewa ta hanyar tashoshi masu ƙarfi a cikin ƙasan diatomaceous da ƙananan pores a cikin kek ɗin tace. Irin wannan barbashi sau da yawa sun fi ƙanƙanta fiye da micropores na duniya diatomaceous. Lokacin da barbashi suka buga bangon tashar, za su iya barin ruwa ya kwarara. Duk da haka, ko zai iya kaiwa wannan matsayi ya dogara da ƙarfin da ba zai iya aiki ba da kuma juriya na barbashi. Ma'auni, irin wannan tsangwama da nunawa suna kama da yanayi, duka biyu na aikin injiniya ne. Ƙarfin tace ƙaƙƙarfan ɓangarorin yana da alaƙa da alaƙa kawai da girman dangi da siffa na tsayayyen barbashi da pores.

3.Adsorption

Tasirin adsorption ya bambanta sosai da hanyoyin tacewa na sama. Ana iya ɗaukar wannan tasirin a matsayin abin jan hankali na electrokinetic, wanda galibi ya dogara ne akan kaddarorin da ke da ƙarfi da kuma ƙasan diatomaceous kanta. Lokacin da barbashi tare da ƙananan pores na ciki a cikin diatomaceous ƙasa sun yi karo a saman ciki na diatomaceous ƙasa, ana jan hankalin su ta hanyar caji dabam dabam, ko kuma barbashi suna jan juna don samar da gungu kuma su manne da ƙasan diatomaceous. Waɗannan duk tasirin adsorption ne.

Sakamakon adsorption ya fi rikitarwa fiye da tasirin biyu na baya. Gabaɗaya an yi imani da cewa dalilin da yasa ƙaƙƙarfan barbashi ƙanana fiye da diamita na pore suna kama da shi galibi saboda:

(1) Ƙungiyoyin intermolecular (wanda kuma ake kira van der Waals jan hankali), ciki har da dipole na dindindin, da aka jawo dipole da dipole nan take;

(2) Kasancewar yuwuwar Zeta;

(3) Tsarin musayar ion.
