Diatomite sefa rubatsiro
Diatomite sefa yekubatsira ine yakanaka microporous chimiro, adsorption performance uye anti compression performance. Haingogone chete kuita kuti mvura yakasefa iwane chiyero chakanaka chekuyerera, asi zvakare kusefa kunze kwezvakarembera zvakamiswa, kuve nechokwadi chekujeka. Diatomite ndiwo masara ekare ekare single celled diatoms. Hunhu hwayo: huremu huremu, porous, simba rakakwirira, kupfeka kuramba, insulation, thermal insulation, adsorption uye kuzadza, nezvimwe.
Diatomite ndiwo masara ekare ekare single celled diatoms. Unhu hwayo: huremu huremu, porous, simba rakakwirira, kupfeka kusagadzikana, kuvhara, kupisa kwemafuta, adsorption uye kuzadza, etc. Iine kugadzikana kwakanaka kwemakemikari. Iyo yakakosha maindasitiri zvinhu zvekupisa kupisa, kugaya, kusefa, adsorption, anticoagulation, demoulding, kuzadza, mutakuri, etc. Inogona kushandiswa zvakanyanya musimbi, indasitiri yemakemikari, magetsi emagetsi, kurima, kemikari fetiraiza, zvinhu zvekuvakisa, zvigadzirwa zvekupisa zvinopisa uye mamwe maindasitiri. Inogona zvakare kushandiswa seindasitiri inoshanda yekuzadza mapurasitiki, rabha, ceramics, kugadzira mapepa, nezvimwe.

Diatomite sefa yekubatsira inogona kukamurwa kuita zvigadzirwa zvakaoma, calcined zvigadzirwa uye flux calcined zvigadzirwa zvinoenderana neakasiyana maitiro ekugadzira. [1]
① Chigadzirwa chakaomeswa
Iyo yakacheneswa, isati yaomeswa uye yakapwanyika silica yakaoma ivhu zvinhu zvakaomeswa pa600 ~ 800 ° C uye zvobva zvapwanywa. Ichi chigadzirwa chine saizi yakanaka kwazvo uye yakakodzera kusefa chaiko. Inowanzoshandiswa pamwe chete nemamwe mafirita aids. Zvizhinji zvezvigadzirwa zvakaomeswa zviyero zvero, asiwo mukaka chena uye chiedza grey. [1]
② Calcined chigadzirwa
Iyo yakacheneswa, yakaomeswa uye yakapwanyika diatomite mbishi inopihwa muchoto inotenderera, yakaverengerwa pa800 ~ 1200 ° C, yobva yapwanywa uye yakagadzikwa kuti iwane zvigadzirwa zvecalcined. Kuenzaniswa neyakaoma chigadzirwa, iyo permeability yechigadzirwa che calcined inopfuura katatu kumusoro. Zvigadzirwa zvecalcined kazhinji zvitsvuku zvitsvuku. [1]
③ Flux calcined chigadzirwa
Iyo yakacheneswa, yakaomeswa uye yakapwanyika diatomite raw material inowedzerwa nediki shoma ye sodium carbonate, sodium chloride uye zvimwe zvinonyunguduka zvinobatsira, calcined pa 900 ~ 1200 ° C, yakapwanyika uye graded kuwana calcined flux. Iyo permeability ye flux calcined chigadzirwa zviri pachena kuti yakawedzera, kanopfuura makumi maviri eiyo yechigadzirwa chakaoma. Flux calcined zvigadzirwa zvinowanzo chena, uye yakareruka pink kana Fe2O3 yemukati yakakwira kana flux dosage idiki. [1]
Sefa
Iyo yekusefa mhedzisiro yediatomite sefa yekubatsira inonyanya kuitwa kuburikidza neanotevera mabasa matatu:
Sieving chiito
Iyi imhando yekusefa kwepamusoro. Kana mvura ichiyerera kuburikidza nediatomite, pore ye diatomite idiki pane particle size yetsvina particles, saka twutsvina twumatwutwutwutwunotadza kupfuura uye tochengetwa. Mhedzisiro iyi inonzi screening. Muchokwadi, iyo yekumusoro keke yekusefa inogona kutariswa senge chidzitiro chine yakaenzana avhareji pore saizi. Kana iyo dhayamita yezvimedu zvakasimba isiri pasi (kana zvishoma zvishoma pane) dhayamita ye diatomite pores, zvimedu zvakasimba zvichange "zvichiongororwa" kunze kwekumiswa, zvichitamba basa rekutsvaira kwepamusoro. [2]
Depth effect
Kudzika mhedzisiro ndiko kuchengetedza mhedzisiro yekusefa kwakadzika. Munguva yekutsvaira kwakadzika, nzira yekuparadzanisa inongoitika mu "mukati" yepakati. Zvimwe zvimedu zvidiki zvisina kuchena zvinopfuura nepamusoro pekeke resefa zvakavharwa neiyo zigzag microporous chiteshi mukati me diatomite uye ma pores akatsetseka mukati mekeke resefa. Zvimedu zvakadai zvinowanzova zviduku kudarika microporous pores ye diatomite. Kana zvimedu zvikarova madziro echiteshi, zvinokwanisika kupatsanura kubva mukuyerera kwemvura, asi kana ichikwanisa kuita izvi, Zvichitemwa nechiyero che inertia simba uye kuramba kunotambura nezvidimbu, iyi yekubira uye yekuongorora chiito yakafanana muchimiro uye ndeye mechanical chiito. Iko kugona kusefa yakasimba zvimedu zvine hukama nehukuru hwehukama uye chimiro chezvimedu zvakasimba uye pores. [2]
Adsorption
Adsorption yakasiyana zvachose kubva pamusoro apa maviri ekusefa nzira. Muchokwadi, mhedzisiro iyi inogona zvakare kutariswa seye electrokinetic kukwezva, iyo inonyanya kuenderana nepamusoro pezvinhu zveakasimba zvimedu uye diatomite pachayo. Kana zvimedu zvine ma pores madiki mu diatomite zvichidhumhana nemukati me porous diatomite, zvinokwezvwa nemhosva dzakapesana, kana kuti zvimedu zvinokwezvana kuti zvigadzire maketani uye kunamatira diatomite, inova adsorption. [2] Adsorption yakanyanya kuoma kupfuura maviri ekutanga. Zvinowanzotendwa kuti zvimedu zvidiki zvidiki pane dhayamita yepore zvinobatwa zvakanyanya nekuti:
(1) The intermolecular force (inonziwo van der Waals attraction) inosanganisira zvachose dipole chiito, induced dipole chiito uye chenguva pfupi dipole chiito;
(2) Kuvapo kweZeta zvinogona;
(3) Ion kuchinjana maitiro.
