1 . Mkhalidwe wa dziko langamafakitale a diatomiteKuyambira m'ma 1960, patatha zaka pafupifupi 60 zachitukuko, dziko langa lapanga njira yopangira ma diatomite ndikugwiritsa ntchito mafakitale achiwiri ku United States kokha. Pakadali pano, pali zoyambira zitatu zopangira ku Jilin, Zhejiang ndi Yunnan. Msika wa diatomite umakhala makamaka zosefera ndi zida zotsekera. Pankhani ya kapangidwe kazinthu, Jilin amatenga zopangira zosefera ngati zinthu zotsogola, Zhejiang amatenga kupanga zida zotchinjiriza zotentha monga zinthu zake zotsogola, ndipo Yunnan amatenga zopangira zotsika zotsika, zida zotchinjiriza matenthedwe, zodzaza ndi zopepuka zopepuka ngati zida zake zotsogola. Kuchokera pamalingaliro a zokolola zapakhomo, kutulutsa kwa diatomite m'dziko langa kwawonjezeka chaka ndi chaka m'zaka zaposachedwa. Pofika chaka cha 2019, kutulutsa kwa diatomite mdziko langa kunali matani 420,000, kuwonjezeka kwa chaka ndi 1.2%. Diatomite imagwiritsidwa ntchito m'magawo ambiri monga zothandizira zosefera, zida zotenthetsera kutentha, zomangamanga, kupanga mapepala, zodzaza, zopangira, zochizira nthaka, matope a diatom, mankhwala ndi zina zotero. Ili ndi mwayi wogwiritsa ntchito kwambiri, koma magawo ena ogwiritsira ntchito sanapangidwebe ndikugwiritsidwa ntchito pamlingo waukulu.

2. Kupititsa patsogolo ndi kagwiritsidwe ntchito ka diatomite m'dziko langa

(1) Kukula kwa zida za Jilin diatomite kudayamba m'ma 1950, ndipo zidagwiritsidwa ntchito makamaka poteteza kutentha ndi zida zotsutsa m'masiku oyamba; chitukuko ndi kupanga zosefera ndi zothandizira zidayamba mu 1970s; mankhwala otchinjiriza a microporous calcium silicate adapangidwa mzaka za m'ma 1980, ndikuchita kafukufuku ndi chitukuko cha ntchito zaulimi. Kuyambira m'ma 1990, diatomite wakhala mtundu watsopano wa zinthu zachilengedwe wochezeka, ndi kufunika msika anapitiriza kuwonjezeka, kukopa ambiri mayunitsi kafukufuku sayansi ndi mabizinezi kuchita kafukufuku mozama ndi chitukuko mankhwala, ndi mchitidwe wa ndende mu makampani diatomite pang'onopang'ono anatulukira. Pali mapaki awiri a diatomite azigawo, omwe ndi Linjiang Diatomite Industrial Concentration Zone ndi Badaogou Diatomite Characteristic Industrial Park ku Changbai County. Pakadali pano, a Jilin Baishan adayamba kupanga makina opanga ma diatomite okhala ndi zosefera, zodzaza ntchito, zomangira zachilengedwe, ndi zida zonyamulira monga zinthu zazikuluzikulu. Pakati pawo, zothandizira zosefera, zotsogola zazinthu zosefera, zimaposa 90% ya gawo la msika; zodzaza zogwira ntchito, monga zopangira mphira, zowonjezera za pulasitiki, zowonjezera zamapepala, zodzaza mapepala opepuka, zowonjezera chakudya, zopangira mating, zodzoladzola ndi zotsukira mano, ndi zina zambiri. Kutulutsa kumaposa matani 50,000; Zida zomangira zachilengedwe, monga ma slabs a dothi la diatom, matailosi apansi, utoto, mapepala apambuyo, matailosi a ceramic, ndi zina zotero, zapangidwa pamlingo waukulu ndipo zili ndi chiyembekezo chabwino cha chitukuko; zida zonyamulira, monga zonyamulira zonyamulira, zonyamulira za nano titanium dioxide, feteleza ndi zonyamula mankhwala ophera tizilombo, etc., Zili ndi mawonekedwe a kumasulidwa pang'onopang'ono, kuteteza chilengedwe, komanso kusakhazikika kwa nthaka, ndipo ali ndi chiyembekezo chachikulu chamsika.

(2) Yunnan ali ndi mabizinesi ambiri omwe amapanga zinthu zokhudzana ndi diatomite, koma pakadali pano mabizinesi ocheperako. Migodi ya Diatomite ku Tengchong kwenikweni ndi migodi yaing'ono yotseguka ya alimi. Malinga ndi zomwe boma likufuna kuteteza zachilengedwe, mabizinesi a diatomite deep processing ku Tengchong ali pachimake, ndipo kwenikweni palibe kutuluka kwazinthu m'mabizinesi a Tengchong kapena Baishan kuti akonze. Zogulitsa zazikulu zamabizinesi adziko lapansi a diatomaceous ku Xundian County ku Yunnan zimaphatikizapo kugwiritsa ntchito misewu ya diatomaceous earth, zosefera, zida zotenthetsera kutentha, zonyamulira mankhwala ophera tizilombo, zopangira mphira, ndi zina zambiri. Pakati pawo, zonyamula mankhwala ndi zonyansa zimagwiritsidwa ntchito pang'ono, ndipo palibe makampani akuluakulu omwe adapangidwa. Kuphatikizidwa ndi mfundo zoteteza zachilengedwe, diatomite ya Yunnan imakhala ndi zinthu zongochitika mwapang'onopang'ono.

(3) Chifukwa cha ndondomeko zotetezera zachilengedwe ku Zhejiang, mabizinesi a diatomite aphatikizidwa, ambiri mwa iwo adatsekedwa, ndipo mizere yopangira idathetsedwa. Pakali pano pali mabizinesi anayi okha a diatomite ku Shengzhou. Zhejiang's diatomite resources ndi zoipa ndipo chitha kugwiritsidwa ntchito pomanga matabwa, refractory njerwa, etc., ndipo sangathe kugwiritsidwa ntchito popanga zosefera. Mabizinesi ku Shengzhou, Zhejiang, amapanga Baishan diatomite zothandizira zosefera, ndikupanga matani 10,000 mpaka 20,000 pachaka, ndipo onse ndi misika yamwazikana yomwe makampani aku Baishan samachita. Zina zonse zimapanga ma fillers, matabwa otsekereza ndi njerwa zomangira ndi zotsekera.

(4) Diatomite ku Inner Mongolia ndi ya “Jiwo mine”, ndipo mikhalidwe ya migodi ndi yoipa. Diatomite yaiwisi yomwe imatha kukumbidwa ndi algae kapena tubular algae, yokhala ndi zinthu zosakhazikika komanso zosakhazikika. Zimangokhala mbale ndi zina zothandizira. Zogulitsa, gawo la msika ndilochepa kwambiri.

3 .Mapangidwe a diatomite ku China Zogulitsa za diatomite za dziko langa zimagwiritsidwa ntchito kwambiri panyumba, ndipo zochepa zimagwiritsidwa ntchito pogulitsa kunja. dziko langa limatumiza kunja kagawo kakang'ono ka diatomite owonjezera mtengo chaka chilichonse. Pambuyo pazaka zopitilira 60, zitha kutulutsa zida zosefera, zida zotenthetsera, zomangira zogwirira ntchito, zomangira, zonyamulira zonyamula ndi simenti zosakanikirana ndi zinthu zina, zomwe zimagwiritsidwa ntchito muzakudya, mankhwala, mankhwala, zomangira, kuteteza chilengedwe, mafuta, zitsulo, kupanga mapepala, mphira, Pali mitundu yopitilira 500 yazinthu, makamaka zogulitsa ndi zoweta nyama, makamaka m'mafakitale olima nyama. kuyeretsa adsorption, zodzaza ntchito, ndi kukonza nthaka. Maziko atatu akuluakulu a diatomite ku Jilin, Zhejiang ndi Yunnan akhazikitsidwa.

Zida za diatomite m'dziko langa zimagwiritsidwa ntchito kwambiri popanga zosefera ndi zida zotsekera. Zina mwa izo, zothandizira zosefera ndiye ntchito yayikulu komanso yodziwika bwino ya diatomite. Zotulutsa zothandizira zosefera nthawi zambiri zimakhala 65% yazogulitsa zonse za diatomite; zodzaza ndi ma abrasives amawerengera pafupifupi 13% ya kuchuluka kwa diatomite, ndipo zotsatsa ndi zoyeretsera zili pafupi Imawerengera 16% yazotulutsa zonse, kuwongolera nthaka ndi feteleza zimatengera pafupifupi 5% yazotulutsa zonse, ndipo zina zili pafupifupi 1%.

Nthawi zambiri, kutulutsa kwa diatomite m'dziko langa kukuwonetsa kukwera kosasunthika, makamaka kuphatikizira zinthu zopangidwa ndi flux-calcined, zinthu zotentha zotsika kwambiri, zinthu zopanda calcined, ndi granulation yopanda calcined. Ndi chitukuko cha chuma cha dziko langa ndi ndondomeko ya mizinda, zofuna za dziko langa za diatomite zikuwonjezeka. Kuchokera mu 1994 mpaka 2019, dziko langa lomwe likuwoneka kuti limamwa diatomite likuwonjezeka chaka ndi chaka.
