Kusefa inzira yakajairika yekurapa muviri inoshandiswa kubvisa zvinhu zvisinganyunguduke kubva mumvura. Nekuda kwekuti zvinhu zvakasimba zviri mumvura zvinowanzova zvidimbu zvakanaka, zvisina chimiro, zvinonamira, uye zviri nyore kuvhara maburi ejira rekusefa, kana zvikasefa zvakasiyana, matambudziko akadai sekuoma kwekusefa uye kusvira kusina kujeka anowanzo buda, izvo zvisingagone kushandiswa mukuita. Kana firita yekubatsira ikawedzerwa kumushonga kana kuti jira rekubatsira rekusefa rakaputirwa pamusoro pejira rekusefa, zvinogona kuvandudza mamiriro aya zvakanyanya. Kumhanya kwekusefa kunokurumidza, filtrate yakajeka, uye firita yakasara yakasimba, iyo inogona kubva pajira rekusefa. Filter aid inonyanya kushandiswa mumaindasitiri akasiyana-siyana idiatomaceous earth. Ndizvo zvatinowanzo dana kuti diatomaceous earth filter aids.

Diatomaceous earth filter aid rudzi rutsva rwemuchina wekuchenesa wepoda unoshanda zvakanyanya unogadzirwa uye unogadziriswa uchishandisa diatomaceous earth sezvinhu zvepakutanga kuburikidza nemaitiro ekugadzirisa akavharwa nguva dzose akadai sekugadzirisa, kurongedza, kurongedza, calcination, uye kuronga. Inogona kugadzira keke refirita rakagadzika rakasimba, rinogona kubata zvidimbu zvidiki mumvura isati yaiswa mucolloidal disapphire palattice skeleton. Nokudaro, ine mukana wakanaka uye inopa chimiro chekeke refirita rine porous, rine porous ye85-95%, iyo inogona kuwana high flow rate mukuparadzanisa kwakasimba nemvura, uye inogona kusefa zvinhu zvakapfava zvakamiswa. Diatomaceous earth filter aids ine kugadzikana kwakanaka kwemakemikari uye inogona kushandiswa zvakavimbika pakusefa chero mvura kunze kwe concentrated caustic solution. Hazvisvibisi mvura yakasefa uye zvinoenderana nezvinodiwa zveFood Hygiene Law. Uye inogona kushandiswa zvinogutsa pamidziyo yakaita sejira refirita, firita paper, simbi wire mesh, porous ceramics, nezvimwewo. Inogona kuwana mhedzisiro inogutsa yekusefa pamichina yakasiyana-siyana yekusefa uye ine mabhenefiti emamwe mafirita ekufambisa. Kushandiswa kwe diatomaceous earth filter aids kuri kuramba kuchipararira. Kunoshandiswa muindasitiri kugadzira zvinhu zvekusefa. Kunoshandiswa muindasitiri yezvikafu pakusefa doro, zvinopfapfaidzwa nemichero, majusi emichero, zvinwiwa zvakasiyana-siyana, manyuchi, mafuta emuriwo, kugadzirira ma enzyme, citric acid, nezvimwewo. Kunoshandiswa muindasitiri yemakemikari pakusefa madhayi, machira, electroplating, solvents, acids, electrolytes, synthetic resins, chemical fibers, glycerol, emulsion, nezvimwewo. Kunoshandiswa muindasitiri yemishonga pakusefa mishonga inorwisa mabhakitiriya, glucose, uye mishonga yechivanhu yeChinese. Panyaya yekuchengetedzwa kwezvakatipoteredza, inoshandiswa pakuchenesa mvura kuchenesa mvura yemumaguta, mvura yekushambira, tsvina, mvura yakasviba yemumaindasitiri, nezvimwewo.

1、 Diatomaceous earth filter aid: Imhando ye diatomaceous earth filter aid inogadzirwa kuburikidza nekuomesa, calcination, kuparadzwa, uye grading, iyo inogona kushandiswa pakupatsanurana kwakasiyana-siyana kwemvura-yakasimba. Mhando dzakasiyana dze diatomaceous earth filter aid dzinosarudzwa pakupatsanurana kwakasiyana-siyana kwemvura-yakasimba. Inoshandiswa zvakanyanya mukuronga. Mapoka mazhinji anoshandisa chimiro chine maburi che diatomaceous earth ne silica shells. Panguva yekugadzirisa, kutarisisa kunofanirwa kupihwa kuchengetedza chimiro uye chimiro chakasiyana chemapfupa e diatomaceous, kusarudza nekungwarira michina yakakodzera yekupwanya nekukuya nemamiriro ehunyanzvi, uye kuchengetedza kusimba kwechimiro che diatomaceous zvakanyanya sezvinobvira kudzivirira kupatsanuka kwechipiri. Midziyo yekukuya inowanzoshandiswa inopwanya mweya.
2、 Mabasa matatu akakosha ekubatsira kusvina mvura pasi pevhu (diatomaceous earth filter) ndeaya: 1. Kuongororwa. Uku kusvina mvura pasi pevhu (surface filtration effect). Kana mvura ichiyerera nepasi pevhu (diatomaceous earth), maburi evhu rediatomaceous adiki pane saizi yezvikamu zvetsvina, saka zvikamu zvetsvina hazvigone kupfuura nepakati uye zvinobatwa. Izvi zvinonzi kusvina mvura pasi pevhu (screening effect). 2. Munguva yekusvina mvura yakadzika, maitiro ekuparadzanisa anoitika mukati mechinhu, uye zvimwe zvikamu zvidiki zvichipfuura nepamusoro pekeke refirita zvichivharwa nemaburi ari mukati mevhu rediatomaceous. Kugona kusefa zvinhu zvakasimba kunoenderana nehukuru uye chimiro chezvikamu zvakasimba nemaburi.
3. Kunyungudika kunoreva kuumbwa kwemaketani pakati pezvikamu zvinokwezvwa nezvinopikisa, nokudaro zvichinamatira zvakasimba kuvhu rediatomaceous.
