1. Cov xwm txheej ntawm kuv lub teb chawsdiatomite kev lag luamTxij li thaum xyoo 1960, tom qab ze li ntawm 60 xyoo ntawm txoj kev loj hlob, kuv lub teb chaws tau tsim cov diatomite ua thiab siv cov saw hlau thib ob rau Tebchaws Meskas. Tam sim no, muaj peb lub hauv paus tsim khoom hauv Jilin, Zhejiang thiab Yunnan. Kev lag luam diatomite feem ntau yog lim cov ntaub ntawv thiab cov ntaub ntawv rwb thaiv tsev. Nyob rau hauv cov nqe lus ntawm cov khoom tsim, Jilin yuav siv sij hawm zus tau tej cov lim pab raws li nws cov khoom ua, Zhejiang yuav siv sij hawm zus tau tej cov thermal rwb thaiv tsev ntaub ntawv raws li nws cov khoom, thiab Yunnan yuav siv sij hawm zus tau tej cov low-end lim pab, thermal rwb thaiv tsev cov ntaub ntawv, muab tub lim thiab lub teeb yuag cov ntaub ntawv raws li nws cov khoom. Los ntawm qhov kev xav ntawm kev tsim khoom hauv tsev, kuv lub teb chaws cov khoom tsim tawm diatomite tau nce xyoo dhau los hauv xyoo tas los no. Raws li xyoo 2019, kuv lub teb chaws cov diatomite tso tawm yog 420,000 tons, ib xyoos ib zaug nce ntawm 1.2%. Diatomite yog siv nyob rau hauv ntau lub teb xws li lim pab, thermal rwb thaiv tsev cov ntaub ntawv, kev tsim kho, papermaking, fillers, catalysts, av kho, diatom av nkos, tshuaj thiab hais txog. Nws muaj kev cia siab rau daim ntawv thov dav, tab sis qee daim ntawv thov teb tseem tsis tau tsim thiab siv rau ntawm qhov loj.

2. Kev tsim kho thiab kev siv diatomite hauv kuv lub tebchaws

(1) Kev txhim kho ntawm Jilin diatomite cov peev txheej tau pib hauv xyoo 1950, thiab feem ntau yog siv los khaws cov khoom cua sov thiab cov ntaub ntawv refractory thaum ntxov; kev txhim kho thiab tsim cov lim pab thiab cov catalysts tau pib hauv xyoo 1970s; microporous calcium silicate rwb thaiv tsev cov khoom tau tsim nyob rau hauv 1980s, thiab ua kev tshawb fawb thiab kev loj hlob rau kev siv ua liaj ua teb. Txij li thaum xyoo 1990, diatomite tau yog ib yam tshiab ntawm cov khoom siv hauv ib puag ncig, thiab kev lag luam xav tau nce ntxiv, nyiam ntau cov kev tshawb fawb tshawb fawb thiab cov lag luam los ua qhov kev tshawb fawb tob tob thiab kev tsim khoom, thiab cov qauv ntawm cov concentration hauv kev lag luam diatomite tau maj mam tshwm sim. Muaj ob lub xeev-theem diatomite chaw ua si, uas yog Linjiang Diatomite Industrial Concentration Zone thiab Badaogou Diatomite Characteristic Industrial Park hauv Changbai County. Tam sim no, Jilin Baishan tau pib tsim cov khoom lag luam diatomite nrog cov ntaub ntawv lim, cov khoom ua haujlwm, cov khoom siv hauv tsev, thiab cov khoom nqa khoom ua cov khoom tseem ceeb. Ntawm lawv, cov khoom siv lim dej, cov khoom tseem ceeb ntawm cov khoom siv lim dej, suav nrog ntau dua 90% ntawm kev lag luam hauv lub tebchaws; cov khoom siv ua haujlwm, xws li cov khoom siv roj hmab, cov khoom siv yas, cov khoom siv ntxiv, cov ntawv ntim cov ntaub ntawv, cov khoom noj khoom haus, cov khoom noj khoom haus, cov tshuaj pleev ib ce thiab cov tshuaj txhuam hniav, thiab lwm yam. Cov zis ntau tshaj 50,000 tons; ecological tsev cov ntaub ntawv, xws li diatom av slabs, pem teb vuas, xim, wallpaper, ceramic vuas, thiab lwm yam., tau raug tsim nyob rau hauv ib tug loj scale thiab muaj kev loj hlob zoo; cov khoom nqa khoom, xws li catalyst carriers, nano titanium dioxide carriers, chiv thiab tshuaj tua kab, thiab lwm yam., Nws muaj cov yam ntxwv ntawm kev tso tawm qeeb, kev tiv thaiv ib puag ncig, thiab tsis-solidification ntawm cov av, thiab muaj kev lag luam dav dav.

(2) Yunnan muaj ntau lub lag luam tsim cov khoom lag luam diatomite, tab sis tam sim no muaj tsawg dua kev lag luam. Diatomite mining hauv Tengchong yog qhov pib me me qhib-qhov mining los ntawm cov neeg ua liaj ua teb. Raws li kev tiv thaiv ib puag ncig ntawm tsoomfwv hauv nroog, diatomite sib sib zog nqus ua cov lag luam hauv Tengchong tau pib stagnated, thiab tsis muaj cov khoom lag luam tawm hauv Tengchong lossis Baishan cov lag luam rau kev ua haujlwm. Cov khoom tseem ceeb ntawm diatomaceous earth enterprises nyob rau hauv Xundian County ntawm Yunnan muaj xws li txoj kev-siv diatomaceous ntiaj teb, lim aids, thermal rwb thaiv tsev cov ntaub ntawv, tshuaj tua kab, roj hmab reinforcing agents, thiab lwm yam. Ntawm lawv, cov tshuaj tua kab thiab dej phwj tshuaj kho mob yog siv nyob rau hauv ib tug me me, thiab tsis muaj kev lag luam loj tau tsim. Ua ke nrog cov cai tiv thaiv ib puag ncig hauv zos, Yunnan's diatomite tsuas muaj cov khoom lag luam sib txawv.

(3) Vim yog cov cai tiv thaiv ib puag ncig hauv zos hauv Zhejiang, cov tuam txhab diatomite tau pib ua ke, feem ntau tau raug kaw, thiab cov kab ntau lawm tau raug tshem tawm. Tam sim no tsuas muaj plaub lub tuam txhab diatomite hauv Shengzhou. Zhejiang cov khoom siv diatomite yog cov khoom tsis zoo thiab tsuas yog siv tau rau cov rwb thaiv tsev, cov cib refractory, thiab lwm yam, thiab tsis tuaj yeem siv los tsim cov khoom siv lim dej. Kev lag luam hauv Shengzhou, Zhejiang, tsim Baishan diatomite rau lim pab, nrog rau ib xyoos twg ntawm 10,000 mus rau 20,000 tons, thiab lawv yog tag nrho cov kev lag luam tawg ua lag luam uas Baishan cov tuam txhab hauv zos tsis ua. Tus so tsim cov fillers, rwb thaiv tsev boards thiab refractory thiab rwb thaiv tsev cib.

(4) Diatomite hauv Inner Mongolia belongs rau "Jiwo mine", thiab cov mining tej yam kev mob tsis zoo. Cov diatomite nyoos uas tuaj yeem raug mined yog qhov pib linear algae lossis tubular algae, nrog cov khoom tsis zoo thiab cov khoom tsis ruaj khov. Nws yog txwv rau daim hlau thiab qee cov catalysts. Cov khoom lag luam, kev lag luam feem ntau me me.

3 .Tuam Tshoj tus diatomite noj qauv kuv lub teb chaws cov khoom diatomite yog tsuas yog siv rau domestic noj, thiab ib tug me me npaum li cas yog siv rau export. kuv lub teb chaws imports me me ntawm tus nqi siab ntxiv diatomite txhua xyoo. Tom qab ntau tshaj 60 xyoo ntawm txoj kev loj hlob, tam sim no nws muaj peev xwm tsim tau cov ntaub ntawv lim, thermal rwb thaiv tsev cov ntaub ntawv, functional fillers, tsev cov ntaub ntawv, catalyst carriers thiab cement sib tov cov ntaub ntawv thiab lwm yam khoom, uas yog siv nyob rau hauv cov khoom noj, tshuaj, tshuaj, tshuaj, tsev cov ntaub ntawv, kev tiv thaiv ib puag ncig, roj av, metallurgy, papermaking, roj hmab, muaj ntau tshaj li 500 hom khoom nyob rau hauv kev ua liaj ua teb, tsiaj txhu, thiab lwm yam ntaub ntawv. adsorption purification, kev ua haujlwm ua haujlwm, thiab txhim kho av. Peb lub hauv paus loj diatomite hauv Jilin, Zhejiang thiab Yunnan tau tsim.

Diatomite cov peev txheej hauv kuv lub tebchaws feem ntau yog siv rau cov ntaub ntawv lim thiab cov ntaub ntawv rwb thaiv tsev. Ntawm lawv, lim kev pab yog kev siv lub ntsiab thiab cov khoom tseem ceeb ntawm diatomite. Cov zis ntawm lim pab feem ntau suav rau 65% ntawm tag nrho cov muag khoom ntawm diatomite; fillers thiab abrasives account rau txog 13% ntawm tag nrho cov zis ntawm diatomite, thiab cov adsorption thiab purification cov ntaub ntawv yog hais txog Nws suav rau 16% ntawm tag nrho cov zis, kev txhim kho av thiab chiv suav txog li 5% ntawm tag nrho cov zis, thiab lwm yam yog hais txog 1%.

Feem ntau, cov zis ntawm diatomite nyob rau hauv kuv lub teb chaws yog qhia ib tug tsis tu ncua upward trend, feem ntau yog cov flux-calcined cov khoom, low-temperature calcined products, non-calcined products, and non-calcined granulation. Nrog rau txoj kev loj hlob ntawm kuv lub teb chaws kev lag luam thiab cov txheej txheem ntawm urbanization, kuv lub teb chaws qhov kev thov rau diatomite cov kev pab yog nce. Los ntawm 1994 mus rau 2019, kuv lub teb chaws pom meej noj diatomite tau nce xyoo los ntawm xyoo.
