Taimakon tace diatomite
Taimakon tace diatomite yana da kyakkyawan tsarin microporous, aikin adsorption da aikin matsawa. Ba wai kawai ya sa ruwan da aka tace ya sami rabo mai kyau ba, amma kuma ya tace daskararrun daskararrun da aka dakatar, yana tabbatar da tsabta. Diatomite shine ragowar tsohuwar diatoms masu cell guda ɗaya. Halayensa: nauyi mai sauƙi, porous, babban ƙarfi, juriya na sawa, rufi, rufin thermal, adsorption da cikawa, da sauransu.

Gyaran Rukuni
Ana iya raba taimakon tace diatomite zuwa busassun samfuran, samfuran calcined da samfuran calcined mai juyi bisa ga tsarin samarwa daban-daban. [1]
① Busasshen samfur
Ana bushe kayan da aka tsarkake, da aka bushe da kuma dakakken silica busasshiyar ƙasan albarkatun ƙasa a 600 ~ 800 ° C sannan a niƙa. Wannan samfurin yana da ƙaƙƙarfan girman barbashi kuma ya dace da madaidaicin tacewa. Ana amfani da shi sau da yawa tare da sauran kayan aikin tacewa. Yawancin busassun samfuran suna da launin rawaya mai haske, amma kuma farar madara da launin toka mai haske. [1]
② Calcined samfur
Ana ciyar da albarkatun da aka tsarkake, busassun da niƙaƙƙen diatomite a cikin tukunyar jujjuyawar, a sanya shi a 800 ~ 1200 ° C, sannan a niƙa kuma an yi darajar don samun samfuran calcined. Idan aka kwatanta da busassun samfur, iyawar samfurin calcined ya fi sau uku girma. Abubuwan Calcined galibi ja ne masu haske. [1]
③ Flux calcined samfur
Ana ƙara ɗanyen diatomite da aka tsarkake, busasshen da niƙaƙƙen tare da ƙaramin adadin sodium carbonate, sodium chloride da sauran kayan taimako na narkewa, calcined a 900 ~ 1200 ° C, niƙa kuma graded don samun juzu'in calcined. Ƙaƙƙarfan ƙaƙƙarfan ƙayyadaddun samfur yana ƙara ƙaruwa, fiye da sau 20 na busasshen samfurin. Flux calcined samfuran galibi fari ne, kuma ruwan hoda mai haske lokacin da abun ciki na Fe2O3 ya yi girma ko kuma juzu'i na ƙarami. [1]
Tace
Tasirin tacewa na taimakon tace diatomite ana aiwatar da shi ta hanyar ayyuka uku masu zuwa:
Sieving mataki
Wannan wani nau'in tacewa ne. Lokacin da ruwa ke gudana ta diatomite, ramin diatomite ya fi ƙanƙanta fiye da girman barbashi na ƙazanta, don haka ƙwayoyin ƙazanta ba za su iya wucewa ba kuma ana riƙe su. Ana kiran wannan tasirin nunawa. A zahiri, ana iya ɗaukar saman kek ɗin tace a matsayin fuskar allo tare da matsakaicin matsakaicin pore daidai. Lokacin da diamita na m barbashi bai kasa da (ko dan kadan kasa da) diamita na diatomite pores, da m barbashi za a "auna" daga cikin dakatarwa, wasa da surface tacewa. [2]
Tasiri mai zurfi
Tasiri mai zurfi shine tasirin riƙewa na zurfin tacewa. A lokacin zurfin tacewa, tsarin rabuwa yana faruwa ne kawai a cikin "ciki" na matsakaici. Wasu ƙananan ɓangarorin ƙazanta da ke wucewa ta saman biredin tace ana toshe su ta tashoshin zigzag microporous a cikin diatomite da mafi kyawun pores a cikin kek ɗin tace. Irin waɗannan barbashi sau da yawa sun fi ƙanƙanta fiye da ƙananan pores na diatomite. Lokacin da barbashi buga bango na tashar, yana yiwuwa a rabu da ruwa kwarara, amma ko zai iya cimma wannan, Ƙayyade da ma'auni na inertia ƙarfi da juriya sha wahala da barbashi, wannan interception da nunawa mataki ne kama a cikin yanayi da kuma kasance a cikin inji mataki. Da ikon tace m barbashi yana da m alaka da dangi size da siffar m barbashi da pores. [2]
Adsorption
Adsorption ya sha bamban da hanyoyin tacewa guda biyu na sama. A gaskiya ma, wannan sakamako kuma za a iya daukarsa a matsayin electrokinetic janye, wanda yafi dogara a kan surface Properties na m barbashi da diatomite kanta. Lokacin da barbashi tare da ƙananan pores a cikin diatomite sun yi karo tare da saman ciki na diatomite mai laushi, ana jawo su ta hanyar cajin da aka saba da su, ko kuma sassan suna jawo hankalin juna don samar da sarƙoƙi kuma suna manne da diatomite, wanda ke da adsorption. [2] Adsorption ya fi rikitarwa fiye da biyun farko. An yi imani da cewa ƙaƙƙarfan barbashi masu ƙanƙanta da diamita na pore sun kasance tarko musamman saboda:
(1) Ƙarfin ƙwayoyin cuta (wanda ake kira van der Waals jan hankali) ya haɗa da aikin dipole na dindindin, aikin dipole da aka haifar da aikin dipole na wucin gadi;
(2) Kasancewar yuwuwar Zeta;
(3) Tsarin musayar ion.
