11 . Meeqaamka dalkaygawarshadaha diatomiteTan iyo 1960-meeyadii, ka dib ku dhawaad 60 sano oo horumarineed, dalkaygu waxa uu sameeyay silsilad warshadeed diatomite ah oo ka faa'iidaysigeeda oo labaad ka xigta Maraykanka. Hadda, waxaa jira saddex saldhig oo wax soo saar ah oo ku yaal Jilin, Zhejiang iyo Yunnan. Suuqa diatomite inta badan waa maaddooyinka shaandhada iyo walxaha dahaarka. Marka la eego qaab dhismeedka wax soo saarka, Jilin waxay qaadataa wax soo saarka qalabka shaandhada sida wax soo saarkeeda hormuudka ah, Zhejiang waxay qaadataa wax soo saarka qalabka dahaadhka kulaylka sida wax soo saarkeeda, Yunnan waxay qaadataa wax soo saarka qalabka shaandhada hoose ee hooseeya, alaabta kuleylka kuleylka, buuxinta iyo qalabka derbiga khafiifka ah sida wax soo saarkeeda. Marka loo eego dhinaca wax-soo-saarka gudaha, wax-soo-saarka diatomit ee dalkaygu wuu kordhay sannadba sannadahan dambe. Laga bilaabo 2019, wax-soo-saarka diatomit ee dalkaygu wuxuu ahaa 420,000 tan, sanad-sannad koror 1.2%. Diatomite waxaa loo isticmaalaa meelo badan sida qalabka shaandhada, alaabta dahaadhka kulaylka, dhismaha, waraaqaha, buuxinta, kicinta, daaweynta ciidda, dhoobada diatom, daawada iyo wixii la mid ah. Waxay leedahay rajooyin codsi oo ballaadhan, laakiin meelaha codsiyada qaarkood weli lama samayn oo si ballaadhan looga faa'iidaysanay.

2. Horumarinta iyo ka faa'iidaysiga diatomit ee dalkayga

(1) Horumarinta kheyraadka Jilin diatomite waxa ay bilaabatay 1950-meeyadii, waxaana inta badan loo isticmaali jiray ilaalinta kulaylka iyo agabka celinaya maalmihii hore; horumarinta iyo soo saarista qalabka shaandhada iyo kicinta ayaa bilaabmay 1970-meeyadii; Alaabta dahaarka silicate ee microporous calcium silicate ayaa la sameeyay 1980-meeyadii, oo Samee cilmi-baaris iyo horumarin codsiyada beeraha. Tan iyo 1990-meeyadii, diatomite waxay ahayd nooc cusub oo ah walxaha deegaanka saaxiibtinimo, iyo baahida suuqa ayaa sii waday inay kordhiso, soo jiidashada tiro badan oo ah cutubyada cilmi-baarista sayniska iyo shirkadaha si ay u sameeyaan cilmi-baaris qoto dheer iyo horumarinta alaabta, iyo isbeddelka diiradda ee warshadaha diatomite ayaa si tartiib tartiib ah u soo baxay. Waxaa jira laba jardiinooyin heer gobol ah oo diatomite ah, kuwaas oo kala ah Linjiang Diatomite Concentration Industrial iyo Badaogou Diatomite Characteristic Industry Park ee Degmada Changbai. Waqtigan xaadirka ah, Jilin Baishan waxay markii hore samaysay nidaam wax soo saar diatomite ah oo leh qalab shaandheyn, buuxinayaal shaqeynaya, qalabka dhismaha deegaanka, iyo alaabada qaadaha oo ah alaabta ugu muhiimsan. Waxaa ka mid ah, qalabka shaandhada, wax soo saarka hormuudka ah ee alaabta shaandhada, ayaa ka dhigan in ka badan 90% saamiga suuqa qaranka; buuxinta shaqaynaysa, sida wakiilada xoojiya caagagga, waxyaalaha lagu daro waraaqaha, buuxinta xaashida fudfudud, waxyaalaha lagu daro quudinta, walxaha dheesha, waxyaalaha la isku qurxiyo iyo buuxinta dawada cadayga, iwm. Wax soo saarka ayaa ka badan 50,000 oo tan; Qalabka dhismaha ee deegaanka, sida dhoobada carrada diatom, sagxadaha sagxadaha, rinjiga, wallpaper, dhoobada dhoobada, iwm, ayaa lagu soo saaray miisaan ballaaran waxayna leeyihiin rajo horumarineed oo wanaagsan; alaabta xambaara, sida xamaaliga, Nano titanium dioxide xambaara, bacriminta iyo cayayaan sidayaal, iwm, Waxay leedahay sifooyinka sii daayo gaabis ah, ilaalinta deegaanka, iyo aan-adkeyn ee ciidda, oo waxay leedahay rajo suuqa oo ballaaran.

(2) Yunnan waxay leedahay ganacsiyo badan oo soo saara alaabada la xiriirta diatomite, laakiin hadda waxaa jira ganacsiyo caadi ah oo yar. Macdanta Diatomite ee Tengchong asal ahaan waa qodida godad yar oo ay beeraleydu sameeyaan. Marka loo eego shuruudaha ilaalinta deegaanka ee dawladda hoose, ganacsiyada farsamaynta qoto-dheer ee diatomite ee Tengchong ayaa asal ahaan hakad galay, asal ahaanna ma jiro wax soo bax ah oo ka baxay shirkadaha Tengchong ama Baishan si loo farsameeyo. Wax soo saarka ugu muhiimsan ee shirkadaha dhulka diatomaceous ee degmada Xundian ee Yunnan waxaa ka mid ah isticmaalka waddooyinka ee diatomaceous earth, qalabka filter, qalabka kulaylka, sidayaasha cayayaanka, walxaha xoojiya caagagga, iwm. Waxaa ka mid ah, sidayaasha cayayaanka iyo wakiilada wasakhda ayaa loo isticmaalaa qadar yar, mana jirto warshad ballaaran oo la sameeyay. Marka lagu daro siyaasadaha ilaalinta deegaanka ee deegaanka, Yunnan's diatomite waxa uu leeyahay badeecooyin goos goos ah oo kaliya.

(3) Sababtoo ah siyaasadaha ilaalinta deegaanka ee deegaanka ee Zhejiang, ganacsiyada diatomite asal ahaan waa la isku daray, kuwaas oo intooda badan la xiray, iyo khadadka wax soo saarka waa la burburiyay. Hadda waxa Shengzhou ka jira afar shirkadood oo diatomite ah. Khayraadka diatomit ee Zhejiang ayaa ah kuwo tayadoodu liidato waxaana loo isticmaali karaa oo keliya looxa dahaadhka ah, lebenka caaga ah, iwm, loomana isticmaali karo in lagu soo saaro alaabta gargaarka shaandhaysa. Shirkadaha Shengzhou, Zhejiang, waxay soo saaraan Baishan diatomite oo loogu talagalay qalabka shaandhada, oo leh wax soo saar sannadle ah 10,000 ilaa 20,000 tan, dhammaantoodna waa suuqyo kala firirsan oo aanay shirkadaha maxalliga ah ee Baishan samayn. Inta soo hartay waxay soo saartaa buuxinta, looxyada dahaarka iyo lebenka dahaadhka ah.

(4) Diatomite gudaha Mongolia gudaha waxaa iska leh "Minada Jiwo", xaaladaha macdantuna waa liitaan. Diatomite ceeriin ah oo la macdan karo asal ahaan waa algae toosan ama algae tubular, oo leh tayo liidata iyo waxqabadka alaabta aan deganayn. Waxay ku kooban tahay taarikada iyo qaar ka mid ah kicinta. Badeecada, saamiga suuqa waa mid aad u yar.

3. Qaab dhismeedka isticmaalka diatomit ee Shiinaha Wax soo saarka diatomit ee dalkayga waxaa inta badan loo isticmaalaa isticmaalka gudaha, qadar yarna waxaa loo isticmaalaa dhoofinta. Dalkaygu wuxuu soo dejiyaa qadar yar oo diatomit ah oo qiimaheedu sarreeyo sanad walba. In ka badan 60 sano oo horumarineed ka dib, waxay hadda soo saari kartaa qalabka shaandhada, qalabka kuleylka kulaylka, buuxinta shaqeynta, qalabka dhismaha, xamuulka qaada iyo sibidhka walxaha isku dhafan iyo alaabada kale, kuwaas oo loo isticmaalo cuntada, daawada, kiimikooyinka, qalabka dhismaha, ilaalinta deegaanka, batroolka, birta, waraaqaha, caag, Waxaa jira in ka badan 500 oo nooc oo badeecado ah, beeraha xoolaha iyo beeraha kale. agabka sifaynta, sifaynta adsorption, buuxinta shaqaynaysa, iyo horumarinta carrada. Saddexda saldhig ee waaweyn ee diatomite ee Jilin, Zhejiang iyo Yunnan ayaa la aasaasay.

Khayraadka Diatomite ee dalkayga waxa inta badan loo isticmaalaa agabka shaandhaynta iyo alaabta dahaarka. Waxaa ka mid ah, gargaarka shaandheynta waa isticmaalka ugu weyn iyo wax soo saarka caadiga ah ee diatomite. Wax soo saarka shaandhada gargaarka shaandhada guud ahaan waxay ka dhigan tahay 65% wadarta iibka diatomite; buuxinta iyo abrasives waxay ku saabsan yihiin 13% wadarta wax soo saarka diatomite, iyo adsorption iyo sifaynta agabku waxay ku saabsan yihiin Waxay ka dhigan tahay 16% wadarta guud ee wax soo saarka, horumarinta carrada iyo bacriminta ayaa ah qiyaastii 5% wadarta guud ee wax soo saarka, kuwa kale waxay ku saabsan yihiin 1%.

Guud ahaan, wax soo saarka diatomite ee dalkaygu waxa uu muujinayaa kor u kac joogto ah, oo inta badan ku lug leh badeecooyinka dareeraha ah, badeecooyinka kulaylka yar, badeecooyinka aan la calcinin, iyo granulation-ka aan la calcinin. Kobcinta dhaqaalaha dalkayga iyo geedi socodka magaalooyinka, baahida dalkaygu ee kheyraadka diatomit waa sii kordhayaa. Laga soo bilaabo 1994 ilaa 2019, dalkayga cunista cad ee diatomite wuu kordhay sanadba sanadka ka dambeeya.
