Kaolin, makamaka kaolin wopyapyala kwambiri, monga chinthu chofunikira kwambiri chosapangidwa ndi chitsulo, nthawi zonse wakhala akuchita gawo lofunika kwambiri mumakampani opanga mapepala chifukwa cha mawonekedwe ake abwino kwambiri. Kaolin wopyapyala womwe umagwiritsidwa ntchito mumakampani opanga mapepala ndi chinthu choyera kwambiri chomwe chimagwiritsidwa ntchito m'malo mwa titanium dioxide yokwera mtengo ndi utoto wina wapamwamba. Monga wopanga zida zopukutira,kaolin yokhala ndi calciumchoyimirira chopyapyala kwambirichozunguliramphero Chopangidwa ndi HCMilling (Guilin Hongcheng) chagwiritsidwa ntchito kwambiri komanso chodziwika bwino popanga kaolin yokhala ndi calcium. Izi ndi chiyambi cha njira yopangira kaolin yokhala ndi calcium:

Zofunikira pa khalidwe la makampani opanga mapepala a kaolin yokhala ndi calcium zikuwonetsedwa makamaka pazofunikira za kukula kwa tinthu tating'onoting'ono, kuyera, mphamvu yobisala, kuyamwa kwa mafuta, kuchuluka kwa viscosity, pH, kuchuluka kwa kuvala ndi zizindikiro zina za kaolin yokhala ndi calcium. Chifukwa cha momwe msika wa kaolin wamba wotsukidwa wakhala ukuchepa chaka ndi chaka chifukwa cha mphamvu ya calcium carbonate yolemera, malonda amsika akhala akuchulukirachulukira, zomwe zapangitsa opanga ambiri kutsatira zomwezo. Kuyambira m'ma 1980, kuchuluka kwakukulu kwa kaolin yokhala ndi malasha kwapezeka (akuti malo osungira omwe angakhalepo amaposa matani 10 biliyoni). Chifukwa cha khalidwe lake lapamwamba komanso zodetsa zochepa zovulaza, kaolin yokhala ndi malasha yakhala chinthu chabwino kwambiri chopangira kaolin yokhala ndi calcium. Chiyembekezo cha msika wa kaolin yokhala ndi calcium yopangidwa kuchokera ku kaolin yokhala ndi malasha ndi chachikulu.

Njira yopangira kaolin yokhala ndi calcium yambiri imaphatikizapo magawo awiri: njira yoponda superfine ndi njira yoyera ya calcium.

1. Njira yopukusira superfine ya njira yopangira kaolin yokhala ndi calcium: njira yopukusira superfine ndi njira yofunika kwambiri yodziwira mtundu wa kaolin. Kuphwanya kaolin superfine yotsatizana ndi malasha ndi kaolin yolimba (kuyambira 5~20mm mpaka 40~80 μ m) Ultrafine (kuyambira 40 mpaka 80 μ M mpaka – 10 μ M kapena – 2 μ m)。kaolin yokhala ndi calciumMphero ya Raymond ndi mphero yozungulira ya kaolin yopangidwa ndi HCMilling (Guilin Hongcheng) ndi zida zopopera zolimba, zomwe zingagwiritsidwe ntchito popopera koyambirira kwa njira yopangira kaolin yopangidwa ndi calcium, ndipo zimatha kukonza kaolin ya malasha ya 80-600;Kaolin wopangidwa ndi calcium wa HLMX choyimirira chopyapyala kwambirichozunguliramphero, mphero yozungulira ndi zida zina zopopera zopyapyala kwambiri ndizoyenera kupopera zopyapyala kwambiri munjira yopangira kaolin yokhala ndi calcium, yomwe imatha kukonza ufa wa kaolin wa 3-45 μ M. Ufa wa kaolin wabwino kwambiri ndi mphero yabwino kwambiri ya ufa wa kaolin yokhala ndi calcium.

2. Njira yoyeretsera ndi kuyeretsa ya njira yopangira kaolin yokhala ndi calcium: Poganizira za mawonekedwe a kaolin yokhala ndi ma organic, ndiye kuti, ili ndi zinthu zina zachilengedwe, kotero kuti kuyera kwake kosaphika ndi 6 ~ 40% yokha, zomwe sizikukwaniritsa zofunikira zamakampani opanga mapepala a kaolin yokhala ndi utoto, kotero njira yochotsera calcium ndi kuyeretsa iyenera kutsatiridwa. Malinga ndi zofunikira zosiyanasiyana za mtundu wa kaolin, ikhozanso kugawidwa m'magulu awiri: kaolin yokhala ndi calcium yotsika kwambiri komanso kaolin yokhala ndi calcium yotsika kwambiri.

Kuyerekeza njira zopangira kaolin yokhala ndi calcium: malingana ndi ngati njira ya superfine ndi yonyowa kapena youma komanso ndondomeko ya njira ya superfine ndi calcination, njira zinayi zopangira zitha kuphatikizidwa, zomwe ndi

(1) njira yonyowa ya superfine yotsatiridwa ndi njira yothira calcium (2) njira youma ya superfine yotsatiridwa ndi njira yothira calcium (3) njira yothira calcium yotsatiridwa ndi njira yonyowa ya superfine (4) njira yothira calcium yotsatiridwa ndi njira youma ya superfine. Chifukwa anthu amamvetsetsa zinthu zosiyanasiyana, njira zomwe zimagwiritsidwa ntchito m'mabizinesi osiyanasiyana ndi zosiyana:

(1) Njira yothira mafuta ochulukirapo (wet superfine calcination) ndi yayitali, koma imatha kusinthasintha kwambiri ndi zinthu zopangira, ndipo khalidwe la zinthuzo lingakwaniritse zosowa za makampani opanga mapepala;

(2) Njira yothira mafuta ndi kunyowetsanso mafuta nthawi zambiri imafuna zida zapadera zowumitsira ndi zida zofalitsira. Njirayi siisinthasintha kwambiri ku zinthu zopangira, koma imatha kupanga zinthu zomwe makampani opanga mapepala amafunikira;

(3) Njira yothira mafuta ouma ndi njira yoyamba yothira mafuta kenako njira yothira mafuta ouma sizingapange kaolin yogwiritsidwa ntchito popanga mapepala (chifukwa cha zida zabwino kwambiri), zomwe zimafuna zipangizo zopangira zapamwamba kwambiri.

Ponseponse, njira yopangira superfine youma isanayambe calcination imakhala yothandiza kwambiri, ndipo chithunzi cha kayendedwe ka ndondomekoyi ndi: miyala yaiwisi → kuphwanya → kuphwanya → superfine youma → calcination → chinthu. Ubwino wa njira iyi ndi: (1) njirayi ndi yochepa, ndipo njira yonseyi imafuna zida zazikulu zitatu kapena zinayi zokha. Ngati HongchengHLMX calcined kaolin ultrafine powder mill ikasankhidwa, pakufunika zida zitatu zokha, zomwe ndi crusher, calcined kaolin ultrafine powder mill, calciner, yomwe ndi yabwino kuyang'anira zonse komanso kukonza nthawi yoyenera; (2) Kugwiritsa ntchito mphamvu ndikoyenera. Munjira iyi, njira yabwino kwambiri ya zinthu imayikidwa patsogolo pa njira ya calcination kuti tipewe vuto logwiritsa ntchito mphamvu zambiri chifukwa cha kuphwanya ndi kuwotcha zinthu. Ngati njira ya calcination ya ufa igwiritsidwa ntchito, ikhoza kuonedwa ngati njira yonse yopangira youma. Ponena za ukadaulo, kugwiritsa ntchito mphamvu ndikoyenera.

Kugwiritsa ntchito kaolin ya malasha kupanga kaolin yokhala ndi calcium yochuluka yopangira mafakitale a mapepala mosakayikira ndi njira yothandiza yogwiritsira ntchito bwino gangue ya malasha. Tiyenera kudziwa kuti njira zoyenera zoyendetsera ntchito ziyenera kusankhidwa malinga ndi chuma cha m'deralo komanso ndalama zomwe zimagwiritsidwa ntchito. Ngati mukufuna kudziwa zambiri za njira zopangira ndi kusankha zida za kaolin yokhala ndi calcium, chonde tiimbireni foni kuti mudziwe zambiri.
