1 . Ọnọdụ obodo mụlọ ọrụ diatomiteKemgbe 1960s, mgbe ihe fọrọ nke nta ka ọ bụrụ afọ 60 nke mmepe, obodo m etolitela usoro nhazi na iji ụlọ ọrụ diatomite nke abụọ na United States. Ugbu a, enwere ntọala mmepụta atọ na Jilin, Zhejiang na Yunnan. Ahịa diatomite bụ tumadi ihe nzacha na ihe mkpuchi. N'ihe banyere usoro ngwaahịa, Jilin na-ewere mmepụta nke ihe nzacha dị ka ngwaahịa ndị na-eduga, Zhejiang na-ewere mmepụta nke ihe mkpuchi ọkụ dị ka ihe ndị na-eduga na ya, Yunnan na-ewerekwa mmepụta nke ihe nzacha dị ala, ihe mkpuchi ọkụ, ihe nkpuchi na ihe mgbidi dị arọ dị ka ngwaahịa ya na-eduga. Site n'echiche nke mmepụta ụlọ, mmepụta diatomite nke obodo m abawanyela kwa afọ na afọ ndị na-adịbeghị anya. N'ihe dị ka afọ 2019, mmepụta diatomite nke obodo m bụ tọn 420,000, mmụba kwa afọ nke 1.2%. A na-eji Diatomite n'ọtụtụ mpaghara dị ka ihe enyemaka nzacha, ihe mkpuchi ọkụ, ihe owuwu, imepụta akwụkwọ, ihe ndị na-emepụta ihe, ihe na-akpali akpali, ọgwụgwọ ala, apịtị diatom, ọgwụ na ihe ndị ọzọ.

2. Mmepe na itinye n'ọrụ nke diatomite na obodo m

(1) Mmepe nke ihe onwunwe Jilin diatomite malitere na 1950s, a na-ejikarị ya eme ihe maka nchekwa okpomọkụ na ihe ndị na-emegharị ihe n'oge mbụ; mmepe na mmepụta nke ihe enyemaka nzacha na ihe mkpali malitere na 1970s; E mepụtara ngwaahịa mkpuchi calcium silicate microporous na 1980, wee mee nyocha na mmepe maka ngwa ọrụ ugbo. Kemgbe 1990s, diatomite abụrụla ụdị ọhụrụ nke ihe omume enyi na gburugburu ebe obibi, na ahịa ahịa anọgidewo na-abawanye, na-adọta ọnụ ọgụgụ dị ukwuu nke ụlọ ọrụ nyocha sayensị na ụlọ ọrụ iji mee nchọpụta miri emi na mmepe ngwaahịa, na usoro nke itinye uche na ụlọ ọrụ diatomite ji nwayọọ nwayọọ pụta. Enwere ogige diatomite ọkwa abụọ nke mpaghara, ya bụ Linjiang Diatomite Industrial Concentration Zone na Badaogou Diatomite Characteristic Industrial Park na Changbai County. Ka ọ dị ugbu a, Jilin Baishan ewepụtala sistemu ngwaahịa diatomite nke nwere ihe nzacha, ihe nzacha arụ ọrụ, ihe ụlọ obibi na ihe ndị na-ebu ibu dị ka ngwaahịa bụ isi. N'ime ha, ihe enyemaka nzacha, ngwaahịa na-eduga nke ihe nzacha, ihe karịrị 90% nke oke ahịa mba; ihe na-arụ ọrụ, dị ka ihe na-eme ka rọba, ihe mgbakwunye rọba, ihe mgbakwunye akwụkwọ, mpempe akwụkwọ dị arọ, ihe mgbakwunye nri, ihe ndị na-edozi matting, ihe ịchọ mma na ntanye eze, wdg. Ihe mmepụta karịrị 50,000 tọn; A na-emepụta ihe ndị e ji ewu gburugburu ebe obibi, dị ka slabs ala diatom, taịlị ala, agba, akwụkwọ ahụaja, taịlị seramiiki, wdg, na-emepụta n'ọtụtụ buru ibu ma nwee atụmanya mmepe dị mma; ihe ndị na-ebu ihe, dị ka ndị na-ebu ibu, nano titanium dioxide na-ebu, fatịlaịza na ndị na-ebu ọgwụ pesticide, wdg, O nwere njirimara nke ntọhapụ ngwa ngwa, nchebe gburugburu ebe obibi, na enweghị ike nke ala, ma nwee atụmanya ahịa sara mbara.

(2) Yunnan nwere ọtụtụ ụlọ ọrụ na-emepụta ngwaahịa ndị metụtara diatomite, mana ugbu a enwere obere azụmaahịa nkịtị. Ngwuputa Diatomite na Tengchong bụ n'ụzọ bụ isi nke ndị ọrụ ugbo na-egwupụta obere oghere. Dabere na ihe achọrọ maka nchekwa gburugburu ebe obibi nke gọọmentị ime obodo, ụlọ ọrụ na-ahụ maka nhazi miri emi diatomite na Tengchong adaala n'ụzọ bụ isi, ọ nweghịkwa ngwaahịa na-apụta na ụlọ ọrụ Tengchong ma ọ bụ Baishan maka nhazi. Ngwaahịa ndị bụ isi nke ụlọ ọrụ diatomaceous ụwa dị na Xundian County nke Yunnan gụnyere ụzọ iji diatomaceous earth, ihe nzacha ihe, ihe mkpuchi ọkụ, ndị na-ebu ọgwụ pesticide, ihe na-agba ume roba, wdg. N'ime ha, a na-eji ndị na-ebu pesticide na ndị na-ahụ maka nsị na-eme ihe n'obere ego, ọ dịghịkwa nnukwu ụlọ ọrụ emebebeghị. Ejikọtara ya na atumatu nchedo gburugburu ebe obibi, Yunnan's diatomite nwere naanị ngwaahịa na-apụtaghị oge.

(3) N'ihi amụma nchedo gburugburu ebe obibi na Zhejiang, ụlọ ọrụ diatomite agbakọwo n'ụzọ bụ isi, nke emechiri ọtụtụ n'ime ha, ma kwatuo ahịrị mmepụta. Enwere naanị ụlọ ọrụ diatomite anọ na Shengzhou ugbu a. Ngwongwo diatomite nke Zhejiang adịghị mma ma enwere ike iji ya naanị maka bọọdụ mkpuchi, brik na-emegharị ihe, wdg, enweghị ike iji ya mepụta ngwaahịa enyemaka nzacha. Ụlọ ọrụ dị na Shengzhou, Zhejiang, na-emepụta Baishan diatomite maka ihe enyemaka nzacha, na-emepụta ihe dị ka tọn 10,000 ruo 20,000 kwa afọ, na ha niile bụ ahịa gbasasịrị nke ụlọ ọrụ Baishan na-adịghị eme. Ndị ọzọ na-emepụta ihe ndochi, mbadamba ihe mkpuchi na brik na-atụgharị na mkpuchi.

(4) Diatomite na Inner Mongolia bụ nke "Jiwo mine", na ọnọdụ Ngwuputa adịghị mma. The raw diatomite nwere ike igwu bụ isi linear algae ma ọ bụ tubular algae, na-adịghị mma na-adịghị akwụ ụgwọ ngwaahịa arụmọrụ. Ọ na-ejedebe na efere na ụfọdụ ihe na-akpali akpali. Ngwaahịa, òkè ahịa dị ntakịrị.

3 .China's diatomite oriri Ọdịdị nke obodo m ngwaahịa diatomite bụ nke a na-ejikarị eme ihe maka oriri ụlọ, a na-ejikwa obere ego maka mbupụ. Obodo m na-ebubata obere ego diatomite bara uru kwa afọ. Mgbe ihe karịrị afọ 60 nke mmepe, ọ nwere ike ugbu a na-emepụta nza ihe, thermal mkpuchi ihe, functional fillers, ụlọ ihe, catalyst na-ebu na ciment agwakọta ihe na ndị ọzọ na ngwaahịa, nke a na-eji na nri, ọgwụ, chemicals, ihe owuwu, gburugburu ebe obibi nchebe, mmanụ ala, metallurgy, papermaking, roba, E nwere ihe karịrị 500 ụdị nke ngwaahịa na ubi ubi, karịsịa na ndị ọzọ na-azụ anụ ụlọ. ihe nzacha, mgbasa ozi mgbasa ozi, ihe ndị na-arụ ọrụ, na nkwalite ala. Ewubela ntọala atọ diatomite atọ dị na Jilin, Zhejiang na Yunnan.

A na-eji akụrụngwa Diatomite na obodo m eme ihe maka ihe nzacha na ihe mkpuchi. N'ime ha, enyemaka nzacha bụ isi ihe eji eme ihe yana ngwaahịa diatomite. Nsonaazụ nke enyemaka nzacha n'ozuzu na-akpata 65% nke ngụkọta ahịa nke diatomite; fillers na abrasives ihe dị ka 13% nke ngụkọta mmepụta nke diatomite, na adsorption na ọcha ihe bụ banyere 16% nke ngụkọta mmepụta, ala mma na fatịlaịza ihe dị ka 5% nke ngụkọta mmepụta, na ndị ọzọ bụ banyere 1%.

N'ozuzu, mmepụta nke diatomite na obodo m na-egosi usoro na-aga n'ihu na-arị elu, karịsịa gụnyere ngwaahịa flux-calcined, ngwaahịa calcined dị ala, ngwaahịa ndị na-abụghị calcined, na granulation na-abụghị calcined. Site na mmepe akụ na ụba obodo m na usoro ime obodo, ọchịchọ obodo m maka akụ diatomite na-abawanye. Site na 1994 ruo 2019, oriri diatomite nke obodo m na-abawanye kwa afọ.
