Ƙa'idar aiki na Diatomite Filter Aid
Ayyukan mataimakan matatun shine canza yanayin haɗuwa na barbashi, ta haka ne ke canza girman rarraba barbashi a cikin tacewa. Diatomite Filter Aidare galibi ya ƙunshi SiO2 mai tsayayyen sinadarai, tare da ɗimbin micropores na ciki, waɗanda ke samar da manyan tsare-tsare daban-daban. A lokacin aikin tacewa, duniya diatomaceous ta fara samar da matsakaicin taimakon tacewa (kafin shafa) akan farantin tacewa. Lokacin da tacewa ta wuce ta wurin taimakon tacewa, ƙaƙƙarfan ɓangarorin da ke cikin dakatarwa sun zama ƙasa mai tari, kuma girman rarraba ya canza. Ana kama ƙazantar manyan barbashi kuma ana riƙe su a saman matsakaicin, suna samar da kunkuntar girman girman rarraba. Suna ci gaba da toshewa da ci abinci tare da irin wannan mai girma, sannu a hankali suna samar da karar tacewa tare da wasu pores.

Saboda diatomaceous ƙasa yana da porosity na kusan 90% da wani babban yanki na musamman, lokacin da ƙananan ƙwayoyin cuta da ƙwayoyin cuta suka shiga cikin ciki da waje na taimakon tacewa, yawanci ana kama su saboda adsorption da wasu dalilai, wanda zai iya rage 0.1 μ The. kau da lafiya barbashi da kwayoyin cuta daga m ya samu mai kyau tace sakamako. Matsakaicin taimakon tace gabaɗaya shine kashi 1-10% na ƙaƙƙarfan taro da aka kama. Idan adadin ya yi yawa, hakika zai shafi haɓaka saurin tacewa.
Tasirin tacewa
Tasirin tacewa na Diatomite Filter Aid yana samuwa ne ta hanyar ayyuka uku masu zuwa:
1. Tasirin dubawa
Wannan wani sakamako ne na tacewa sama, inda lokacin da ruwa ke gudana ta cikin diatomaceous ƙasa, ramukan diatomaceous ƙasa sun fi ƙanƙanta girman barbashi na ƙazanta, don haka ƙwayoyin ƙazanta 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 m barbashi bai kasa da (ko dan kadan kasa da) da pore diamita na diatomaceous ƙasa, da m barbashi za a "kariya" daga cikin dakatar, wasa da rawa a surface tacewa.
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 matsakaici. Wasu ƙananan ɓangarorin ƙazanta waɗanda ke wucewa ta saman biredin tace suna toshewa ta hanyar iskar microporous tashoshi a cikin ƙasan diatomaceous da ƙananan pores a cikin kek ɗin tacewa. Waɗannan barbashi galibi suna ƙasa da ƙananan ƙwayoyin cuta a cikin ƙasa diatomaceous. Lokacin da barbashi suka yi karo da bangon tashar, yana yiwuwa a cire daga kwararar ruwa. Duk da haka, ko za su iya cimma wannan ya dogara ne akan ma'auni tsakanin ƙarfin inertial da juriya na barbashi. Wannan tsangwama da aikin nunawa iri ɗaya ne a cikin yanayi kuma suna cikin aikin injina. Ƙarfin tace ƙaƙƙarfan ɓangarorin yana da alaƙa da alaƙa kawai da girman dangi da siffa na tsayayyen barbashi da pores.
3. Tasirin Adsorption
Tasirin adsorption ya sha bamban da hanyoyin tacewa guda biyu da aka ambata a sama, kuma ana iya ganin wannan tasirin a matsayin jan hankali na electrokinetic, wanda galibi ya dogara ne akan kaddarorin da ke da ƙarfi da kuma diatomaceous ƙasa kanta. Lokacin da barbashi tare da ƙananan pores na ciki suka yi karo da saman ƙasan diatomaceous mara kyau, ana jan hankalin su ta hanyar caji dabam-dabam ko samar da gungu na sarkar ta hanyar jan hankalin juna tsakanin barbashi da kuma manne da ƙasan diatomaceous, waɗanda duk na adsorption ne. Sakamakon adsorption ya fi rikitarwa fiye da na biyu na farko, kuma an yi imani da cewa dalilin da yasa m barbashi tare da karami pore diamita aka intercepted ne yafi saboda:
(1) Ƙungiyoyin intermolecular (wanda kuma aka sani da jan hankalin van der Waals), ciki har da hulɗar dipole na dindindin, ƙaddamar da hulɗar dipole, da kuma hulɗar dipole nan take;
(2) Kasancewar yuwuwar Zeta;
(3) Tsarin musayar ion.
