Pakalipano, njira zopangira heavy calcium carbonate makamaka zimaphatikizapo njira youma ndi njira yonyowa.Njira youma nthawi zambiri imatulutsa kashiamu wolemera ndi mauna osakwana 2500.Ngati kashiamu wolemera wokhala ndi mauna opitilira 2500 apangidwa, kugaya konyowa kumagwiritsidwa ntchito makamaka, ndipo kugaya kowuma ndi gawo loyamba la kugaya konyowa.Chonyowa akupera katundu kashiamu ali ndi makhalidwe abwino processing fluidity, pamwamba kuwala pamwamba ndi katundu makina kwambiri, ndipo zimagwiritsa ntchito mankhwala pulasitiki;Ndi kuwonjezeka kwa fineness, chiŵerengero chosiyana, kusungunuka ndi kuyera kwa utoto wa latex wopaka mkati mwa makoma amkati kumawonjezeka pang'onopang'ono.Choncho, ochulukirachulukira katundu kashiamu opanga ayamba kukhala kupanga chonyowa akupera katundu kashiamu kuyouma ndondomeko katundu kashiamu processing mzere mzere.HCMilling(Guilin Hongcheng), monga wopanga calcium yochulukampheromakina, adzayambitsa kupanga ndi kugwiritsa ntchito chonyowa akupera heavy kashiamu.

1, Kupanga chonyowa akupera heavy kashiamu carbonate: choyamba, kuyimitsidwa kwa youma akupera katundu kashiamu ufa amaikidwa mucalcium yochulukampherokwa kuphwanya kwina, ndiyeno kopitilira muyeso-chabwino heavy kashiamu carbonate amakonzedwa pambuyo madzi m'thupi ndi kuyanika.Njira yopanga chonyowa akupera heavy calcium ndi motere:

(1) Miyala yaiwisi → kuthyola nsagwada → kashiamu carbonate Raymond mphero → mphero yonyowa yosakaniza kapena makina ovundukula (panthawi, masitepe angapo kapena kuzungulira) → kagulu konyowa → kuyang'ana → kuyanika → kuyambitsa → matumba (wokutidwa ndi heavy calcium carbonate).Gulu la Wet ultrafine limawonjezedwa pamayendedwe oyenda, omwe amatha kulekanitsa zinthu zoyenerera munthawi yake ndikuwongolera magwiridwe antchito.Zida zonyowa zamtundu wa ultrafine makamaka zimaphatikizapo chimphepo chaching'ono chamkuntho, chopingasa spiral classifier ndi disc classifier.The slurry pambuyo gulu ndi ochepa, ndipo nthawi zina thanki sedimentation chofunika.Njirayi ili ndi zizindikiro zabwino zachuma, koma magulu ndi ovuta kugwira ntchito.Pakadali pano, palibe zida zamagulu zonyowa kwambiri za ultrafine.

(2) Miyala yaiwisi → kuthyola nsagwada → kashiamu carbonate Raymond mphero → mphero yonyowa yosonkhezera → kuwunika → kuyanika → kuyambitsa → matumba (kashiamu wodzaza ndi wolemera).

(3) Miyala yaiwisi → kuthyola nsagwada →kashiamu carbonate Raymond mphero → mphero yonyowa kapena makina ovundukula (kanthawi kochepa, masitepe angapo kapena kuzungulira) → kuwunika (kutchingira mapepala kalasi heavy calcium slurry).

2, Ubwino wa chonyowa akupera katundu kashiamu: poyerekeza youma akupera katundu kashiamu, chonyowa akupera katundu kashiamu ali ndi ubwino zoonekeratu.Zikuwonekera kwambiri m'mbali zotsatirazi:

(1) Tinthu kukula: superfine heavy kashiamu opangidwa ndi chonyowa akupera ndi zabwino tinthu kukula, makamaka kubala mankhwala ndi ma meshes oposa 3000, <2 μ Zomwe zili m'm zimatha kufika 90%, pamene kukula kwa mbewu zouma ndizofanana. coarse, makamaka kupanga zinthu zosakwana 2500 mesh.

(2) Tinthu kukula kugawa: tinthu kukula kugawa katundu kashiamu opangidwa ndi chonyowa ndondomeko ndi yopapatiza, ndi kugawa limodzi kapena iwiri pachimake;Komabe, tinthu kukula kugawa katundu kashiamu opangidwa ndi youma njira ndi lonse, ndipo ndi mu mawonekedwe a nsonga iwiri kapena angapo.

(3) Granular: Chifukwa cha zosiyanasiyana akupera chilengedwe ndi maganizo akafuna particles pa akupera, ndi particles chonyowa akupera katundu kashiamu zambiri ozungulira kapena quasi-spherical, pamene youma njira mankhwala ambiri amorphous ndi m'mbali zoonekeratu ndi ngodya.

(4) Chinyezi: Kashiamu wonyowa kwambiri wolemera kwambiri wadutsa mu kuyanika popanga, ndipo chinyezi nthawi zambiri chimayendetsedwa pansi pa 0.3%, koma chinyontho cha calcium yolemera chomwe chimapangidwa ndi njira youma sichingawongoleredwe, nthawi zambiri kuposa 1%.Choncho, kubalalitsidwa ndi fluidity ya chonyowa superfine heavy kashiamu pa ndondomeko kusinthidwa mwachionekere bwino kuposa opangidwa ndi youma njira.

3,Ikanicalcium yochulukamphero kunyowa akupera calcium heavy:

(1) Utoto wa emulsion: Pamene calcium carbonate imagwiritsidwa ntchito ngati chodzaza mu utoto wa latex, imagwira ntchito yodzaza ndipo imakhala ndi ntchito yowuma yophimba, yomwe imachepetsa mtengo wa utoto wa latex, komanso imakhala ngati chigoba, ndikuwongolera filimu makulidwe, kuuma, madzi kukana ndi scrub resistance.Chifukwa chake, kugwiritsa ntchito kashiamu wolemera mumakampani opanga zokutira kumachulukirachulukira.

(2) Permeable nembanemba: The dispersity ndi tinthu kukula (kukula ndi kugawa) kashiamu carbonate ufa kudziwa fluidity wa ufa wokha, komanso mwachindunji zimakhudza kupanga liwiro ndi ndondomeko bata wa permeable nembanemba, amene ali ndi udindo waukulu mu kukhazikika kwa porosity, kapangidwe ka pore, permeability ndi makina amakina a nembanemba yotheka.Kugwiritsa ntchito kashiamu wolemera wopangidwa ndi chonyowa akupera monga "porogen" ali otsika mayamwidwe mafuta mtengo, bwino kubalalitsidwa ndi fluidity, komanso kuchepetsa kwambiri kuchuluka kwa utomoni chonyamulira, plasticizer, lubricant ndi zina zowonjezera.

(3) Colour masterbatch: Colour masterbatch coloring ndiye njira yomwe imagwiritsidwa ntchito kwambiri popaka utoto wapulasitiki pakadali pano, yomwe nthawi zambiri imakhala ndi utomoni wonyamula, pigment ndi zowonjezera.Kafukufuku wambiri awonetsa kuti kugwiritsa ntchito calcium carbonate, wollastonite kapena barium sulfate m'malo mwa inki kuti mukonzekere mtundu wa masterbatch kumatha kupititsa patsogolo kufalikira kwa inki ndikuchepetsa mtengo wopangira popanda kuchepetsa magwiridwe antchito amtundu wa masterbatch.Kafukufuku wina wasonyeza kuti mtundu masterbatch wokonzeka ndi chonyowa akupera kashiamu bicarbonate m'malo titaniyamu woipa, pamene kuchuluka m'malo ndi 20%, utoto ntchito akadali osasintha, ndi ntchito ndi ofanana kwambiri ndi wa pigment koyera, ndi yaing'ono mtundu kusiyana.

Monga wopanga calcium yochulukampheromakina, ndiHCQ, HC mndandanda waukulu wolemera wa calcium Raymond mphero, HLM heavy calcium coarse powder ofukulakugayampherondi zina calcium yochulukampherozida opangidwa ndi HCMilling(Guilin Hongcheng) akhala ankagwiritsa ntchito ndipo anapambana mbiri yabwino kutsogolo-mapeto youma kupanga chonyowa akupera lolemera kashiamu.Ngati mukufuna kupanga mphero yonyowa ya calcium yolemera ndipo mukufuna zida zowuma zowuma kutsogolo, lemberani HCM kuti mudziwe zambiri za zida.
