(1) Tsoelo-pele ea lisebelisoa tsa Jilin diatomite e qalile lilemong tsa bo-1950, 'me e ne e sebelisoa haholo-holo bakeng sa ho boloka mocheso le thepa ea ho hanyetsa matsatsing a pele; ntshetsopele le tlhahiso ea li-filter aids le li-catalyst li qalile ka bo-1970; Lihlahisoa tsa li-insulation tsa calcium silicate tse nyenyane li ile tsa ntlafatsoa lilemong tsa bo-1980, 'me Etsa lipatlisiso le nts'etsopele bakeng sa lisebelisoa tsa temo. Ho tloha lilemong tsa bo-1990, diatomite e 'nile ea e-ba mofuta o mocha oa thepa ea tikoloho,' me tlhokahalo ea 'maraka e ntse e eketseha, e hohela palo e kholo ea lihlopha tsa lipatlisiso tsa saense le likhoebo ho etsa lipatlisiso tse tebileng le nts'etsopele ea lihlahisoa,' me mokhoa oa ho tsepamisa mohopolo indastering ea diatomite o hlahile butle-butle. Ho na le lirapeng tsa boikhathollo tse peli tsa "diatomite" tsa boemo ba profensi, e leng Linjiang Diatomite Industrial Concentration Zone le Badaogou Diatomite Characteristic Industrial Park Seterekeng sa Changbai. Hajoale, Jilin Baishan o qalile a thehile sistimi ea sehlahisoa sa diatomite e nang le lisebelisoa tsa sefa, li-filler tse sebetsang, lisebelisoa tsa kaho ea tikoloho le lisebelisoa tsa ho tsamaisa e le lihlahisoa tsa mantlha. Har'a tsona, li-filter aids, sehlahisoa se ka sehloohong sa lisebelisoa tsa filthara, se ikarabella ho feta 90% ea karolo ea 'maraka oa naha; li-filler tse sebetsang, tse kang li-agent tse matlafatsang rabara, li-additives tsa polasetiki, li-additives tsa pampiri, li-fillers tsa pampiri tse bobebe, li-feed additives, matting agents, litlolo le litlolo tsa meno, joalo-joalo. Phallo e feta lithane tse 50,000; lisebelisoa tsa kaho ea tikoloho, tse kang li-slabs tsa mobu oa diatom, lithaele tsa fatše, pente, wallpaper, lithaele tsa ceramic, joalo-joalo, li hlahisitsoe ka tekanyo e kholo 'me li na le menyetla e metle ea tsoelo-pele; lisebelisoa tse tsamaisang thepa, joalo ka bajari ba li-catalyst, bajari ba nano titanium dioxide, manyolo le bajari ba chefo e bolaeang likokoanyana, joalo-joalo, E na le litšobotsi tsa ho lokolloa butle, ts'ireletso ea tikoloho le ho se tiise mobu, 'me e na le tebello e pharaletseng ea mmaraka.

(2) Yunnan e na le likhoebo tse ngata tse hlahisang lihlahisoa tse amanang le diatomite, empa hajoale ho na le likhoebo tse fokolang tse tloaelehileng. Meepo ea Diatomite Tengchong ke merafo e menyenyane e bulehileng e etsoang ke lihoai. Ho ea ka litlhoko tsa ts'ireletso ea tikoloho tsa mmuso oa lehae, likhoebo tsa ts'ebetso tse tebileng tsa diatomite tse Tengchong ha e le hantle li theohile, 'me ha e le hantle ha ho na tlhahiso ea lihlahisoa likhoebong tsa Tengchong kapa Baishan bakeng sa ho sebetsa. Lihlahisoa tse ka sehloohong tsa lik'hamphani tsa lefats'e tsa diatomaceous Seterekeng sa Xundian sa Yunnan li kenyelletsa lefats'e la diatomaceous tse sebelisoang tseleng, li-filters, lisebelisoa tsa ho futhumatsa mocheso, bajari ba chefo e bolaeang likokoanyana, lisebelisoa tse matlafatsang rabara, joalo-joalo Har'a bona, bajari ba likokoana-hloko le lisebelisoa tsa likhoerekhoere ba sebelisoa ka chelete e nyenyane, 'me ha ho na indasteri e kholo e entsoeng. Ha mmoho le maano a ts'ireletso ea tikoloho, diatomite ea Yunnan e na le lihlahisoa tsa nakoana feela.

(3) Ka lebaka la melaoana ea lehae ea ts'ireletso ea tikoloho Zhejiang, likhoebo tsa diatomite li kopantsoe, tseo boholo ba tsona li koetsoeng, 'me likhoele tsa tlhahiso li ile tsa qhaloa. Hajoale ho na le likhoebo tse 'ne feela tsa diatomite Shengzhou. Lisebelisoa tsa diatomite tsa Zhejiang ha li na boleng bo botle 'me li ka sebelisoa feela bakeng sa liboto tsa ho pata, litene tse refractory, joalo-joalo,' me li ke ke tsa sebelisoa ho hlahisa lihlahisoa tsa lithuso tsa filthara. Likhoebo tse Shengzhou, Zhejiang, li hlahisa Baishan diatomite bakeng sa lisebelisoa tsa ho hloekisa, ka tlhahiso ea selemo le selemo ea lithane tse 10,000 ho isa ho tse 20,000, 'me kaofela ke limmaraka tse qalikaneng tseo lik'hamphani tsa lehae tsa Baishan li sa li etseng. Tse ling kaofela li hlahisa li-filler, liboto tsa ho kenya letsoho le litene tse refractory le tsa ho kenya letsoho.

(4) Diatomite e Inner Mongolia ke ea "morafo oa Jiwo", 'me maemo a merafo a futsanehile. Diatomite e tala e ka rafshoang ha e le hantle ke algae ea linear kapa algae ea tubula, e nang le boleng bo tlaase le ts'ebetso e sa tsitsang ea sehlahisoa. E lekanyelitsoe ho lipoleiti le li-catalysts tse ling. Sehlahisoa, karolo ea 'maraka e nyane haholo.

Sebopeho sa China sa tšebeliso ea diatomite Lihlahisoa tsa naha ea heso tsa diatomite li sebelisoa haholo-holo ho sebelisoa malapeng, 'me chelete e nyenyane e sebelisoa ho ea linaheng tse ling. naha ea heso e reka kantle ho naha chelete e nyane ea diatomite ea boleng bo holimo selemo le selemo. Kamora lilemo tse fetang 60 tsa nts'etsopele, joale e se e khona ho hlahisa lisebelisoa tsa filthara, lisebelisoa tsa ho futhumatsa mocheso, li-filler tse sebetsang, lisebelisoa tsa moaho, li-catalyst carriers le lisebelisoa tse tsoakiloeng tsa samente le lihlahisoa tse ling, tse sebelisoang lijong, meriana, lik'hemik'hale, thepa ea kaho, ts'ireletso ea tikoloho, petroleum, metallurgy, papermaking, rabara, Ho na le mefuta e fetang 500 ea lihlahisoa le lihlahisoa tse ling indastering ea temo ea liphoofolo, haholo-holo indastering ea temo ea liphoofolo. tlhoekiso ea adsorption, li-filler tse sebetsang hantle, le ntlafatso ea mobu. Ho thehiloe metheo e meraro e meholo ea diatomite Jilin, Zhejiang le Yunnan.

Lisebelisoa tsa diatomite naheng ea heso li sebelisoa haholo-holo bakeng sa lisebelisoa tsa sefa le lisebelisoa tsa ho pata. Har'a tsona, thuso ea filthara ke ts'ebeliso ea mantlha le sehlahisoa se tloaelehileng sa diatomite. Sephetho sa lithuso tsa filthara hangata se etsa 65% ea kakaretso ea thekiso ea diatomite; li-fillers le li-abrasives li etsa hoo e ka bang 13% ea kakaretso ea lihlahisoa tsa diatomite, 'me thepa ea adsorption le ea tlhoekiso e mabapi le E etsa karolo ea 16% ea kakaretso ea lihlahisoa, ntlafatso ea mobu le manyolo li etsa hoo e ka bang 5% ea kakaretso,' me tse ling li ka bang 1%.

Ka kakaretso, tlhahiso ea diatomite naheng ea heso e bonts'a mokhoa o tsitsitseng oa ho nyoloha, haholo-holo o kenyelletsang lihlahisoa tse nang le flux-calcined, lihlahisoa tse nang le mocheso o tlaase, lihlahisoa tse sa calcined, le granulation e sa calcined. Ka nts'etsopele ea moruo oa naha ea heso le ts'ebetso ea ho ea litoropong, tlhoko ea naha ea heso ea lisebelisoa tsa diatomite e ntse e eketseha. Ho tloha ka 1994 ho isa ho 2019, tšebeliso e bonahalang ea naha ea heso ea diatomite e ntse e eketseha selemo le selemo.
