Diatomite filter aids inogona kukamurwa kuita yakaoma algae zvigadzirwa, calcined zvigadzirwa uye flux calcined zvigadzirwa zvinoenderana neakasiyana maitiro ekugadzira.

① Zvigadzirwa zvakaomeswa
Mushure mekucheneswa, kusati kwaoma uye kutumirwa, iyo mbishi yakaomeswa pa600-800 ° C, uye yobva yaitwa.Rudzi urwu rwechigadzirwa rune saizi yakanaka kwazvo uye yakakodzera kusefa chaiko.Inowanzoshandiswa pamwe chete nemamwe mafirita aids.Zvigadzirwa zvakaomeswa zvakanyanya kupenya yero, asiwo mukaka chena uye grey grey.

② Calcined zvigadzirwa
Iyo yakacheneswa, yakaomeswa uye yakapwanyika diatomite inodyiswa muchoto inotenderera, yakarukwa pa800-1200 ° C, yobva yapwanywa uye yakagadzikwa kuti iwane chigadzirwa chakaverengerwa.Kuenzaniswa neyakaoma zvigadzirwa, iyo permeability yezvigadzirwa zve calcined zvinodarika katatu zvakakwirira.Zvigadzirwa zvecalcined kazhinji zvitsvuku zvitsvuku.

③ Flux calcined zvigadzirwa
Mushure mekucheneswa, kuomeswa nekukuya, iyo mbishi ye diatomite inowedzerwa nekashoma sodium carbonate, sodium chloride uye imwe inonyungudika AIDS, uye calcined pa 900 ~ 1200 ° C. mushure mekugaya uye particle size grading, iyo flux calcined product is akawana.Iyo permeability ye flux calcined chigadzirwa zviri pachena kuti yakawedzera, iyo inodarika nguva makumi maviri eiyo yechigadzirwa chakaoma.Iyo flux calcined zvigadzirwa zvinonyanya kuchena, uye yakareruka pink kana zvirimo zveFe2O3 zvakakwirira kana huwandu hwekuyerera hudiki.
