Pakadali pano, njira zopangira calcium carbonate yolemera makamaka zimaphatikizapo njira youma ndi njira yonyowa. Njira youma nthawi zambiri imapanga calcium yolemera yokhala ndi maukonde osakwana 2500. Ngati calcium yolemera yokhala ndi maukonde opitilira 2500 yapangidwa, kuponda konyowa kumagwiritsidwa ntchito kwambiri, ndipo kuponda kouma ndiye gawo loyamba la kuponda konyowa. Kuponda konyowa calcium yolemera kumakhala ndi mawonekedwe a kusinthasintha kwabwino, kuwala kwakukulu pamwamba komanso mawonekedwe abwino amakina, ndipo imagwiritsidwa ntchito kwambiri pazinthu zapulasitiki; Ndi kuwonjezeka kwa kupyapyala, kusiyana kwa kusiyana, kusambitsidwa ndi kuyera kwa utoto wa latex womwe umayikidwa pamakoma amkati kumawonjezeka pang'onopang'ono. Chifukwa chake, opanga calcium yolemera ambiri ayamba kupanga kupanga calcium yonyowa kuchokera kumzere wopangira calcium wolemera wopangira njira youmaHCMilling (Guilin Hongcheng), monga wopanga calcium yolemeramphero yoperamakina, adzayambitsa kupanga ndi kugwiritsa ntchito calcium yochuluka yonyowa.

1, Kupanga calcium carbonate yonyowa pogaya: choyamba, kuyimitsidwa kwa ufa wouma wogaya wolemera wa calcium kumayikidwa mucalcium yolemeramphero yoperakuti iphwanyidwenso, kenako calcium carbonate yolemera kwambiri imakonzedwa pambuyo poti madzi atha ndipo auma. Njira yopangira calcium yolemera yonyowa ndi iyi:

(1) Matanthwe osaphika → kuswa nsagwada → calcium carbonate Raymond mill → mphero yosakaniza yonyowa kapena makina ochotsera (osakhalitsa, okhala ndi magawo ambiri kapena ozungulira) → chogawa chonyowa → kuwunikira → kuyanika → kuyambitsa → thumba (calcium carbonate yolemera yokhala ndi zokutira). Kugawa kwa wet ultrafine kumawonjezeredwa ku kayendedwe ka ndondomeko, komwe kumatha kulekanitsa zinthu zoyenera panthawi yake ndikuwonjezera magwiridwe antchito. Zipangizo zogawa za wet ultrafine makamaka zimaphatikizapo chimphepo chaching'ono cham'mimba mwake, chogawa chozungulira chopingasa ndi chogawa cha disc. Kugawa kwa matope pambuyo pa kugawa kumakhala kopyapyala, ndipo nthawi zina thanki ya sedimentation imafunika. Njirayi ili ndi zizindikiro zabwino zachuma, koma kugawa kumakhala kovuta. Pakadali pano, palibe zida zogawa za wet ultrafine zogwira ntchito kwambiri.

(2) Matanthwe osaphika → kuswa nsagwada → calcium carbonate Raymond mill → mphero yonyowa → kuyeretsa → kuumitsa → kuyambitsa → kuyika thumba (calcium yochuluka yodzaza).

(3) Matanthwe osaphika → kuswa nsagwada →calcium carbonate Raymond mill → mphero yonyowa kapena makina ochotsera (osakhalitsa, okhala ndi magawo ambiri kapena ozungulira) → kufufuza (kuphimba pepala ndi calcium wambiri).

2, Ubwino wa kupukusa calcium yolemera mwa kunyowa: Poyerekeza ndi kupukusa calcium yolemera mwa kunyowa, kupukusa calcium yolemera mwa kunyowa kuli ndi ubwino woonekeratu. Makamaka izi zimawonekera m'mbali zotsatirazi:

(1) Kukula kwa tinthu: calcium yolemera kwambiri yopangidwa ndi kupukutira konyowa imakhala ndi tinthu tating'onoting'ono, makamaka imapanga zinthu zokhala ndi ma meshes opitilira 3000, <2 μ Zomwe zili mu m nthawi zambiri zimatha kufika 90%, pomwe kukula kwa tinthu tating'onoting'ono ta zinthu zouma kumakhala kolimba, makamaka imapanga zinthu zosakwana ma meshes 2500.

(2) Kugawa kwa tinthu tating'onoting'ono: kugawa kwa tinthu tating'onoting'ono ta calcium yolemera yomwe imapangidwa ndi njira yonyowa ndi kopapatiza, komwe kumagawidwa ndi tinthu tating'onoting'ono ta calcium yolemera yomwe imapangidwa ndi njira youma; Komabe, kugawa kwa tinthu tating'onoting'ono ta calcium yolemera yomwe imapangidwa ndi njira youma ndi kokulirapo, ndipo kumakhala ngati tinthu tating'onoting'ono ta calcium tochuluka kapena tambiri.

(3) Zidutswa: Chifukwa cha malo osiyanasiyana opukutira ndi momwe tinthu tating'onoting'ono timagwirira ntchito popukutira, tinthu tating'onoting'ono ta calcium yochuluka yopukutira nthawi zambiri timakhala tozungulira kapena tozungulira, pomwe tinthu tating'onoting'ono tomwe timauma nthawi zambiri timakhala topanda mawonekedwe okhala ndi m'mbali ndi ngodya zomveka bwino.

(4) Chinyezi: Kalisiamu wonyowa kwambiri wadutsa mu ndondomeko yowuma popanga, ndipo chinyezi nthawi zambiri chimayendetsedwa pansi pa 0.3%, koma chinyezi cha kalisiamu wonyowa chomwe chimapangidwa ndi njira youma sichingalamuliridwe, nthawi zambiri chimakhala choposa 1%. Chifukwa chake, kufalikira ndi kusinthasintha kwa kalisiamu wonyowa kwambiri panthawi yosintha n'kwabwino kuposa komwe kumapangidwa ndi njira youma.

3、Ikanicalcium yolemeramphero yopera kupukusa calcium yochuluka m'madzi:

(1) Utoto wa emulsion: Pamene calcium carbonate imagwiritsidwa ntchito ngati chodzaza mu utoto wa latex, imagwira ntchito yodzaza ndipo imakhala ndi ntchito yothira utoto wouma, zomwe sizimangochepetsa mtengo wa utoto wa latex, komanso zimagwira ntchito ngati mafupa, ndikuwonjezera makulidwe a filimu, kuuma, kukana madzi ndi kukana kutsuka. Chifukwa chake, kugwiritsa ntchito calcium yochuluka mumakampani opanga zokutira nyumba kumakhala kwakukulu.

(2) Nembanemba yolowa: Kufalikira ndi kukula kwa tinthu tating'onoting'ono (kukula ndi kufalikira) kwa ufa wa calcium carbonate kumatsimikizira kusuntha kwa ufawo, komanso kumakhudza mwachindunji liwiro lopanga ndi kukhazikika kwa njira yolowera, zomwe zimakhala ndi gawo lofunika kwambiri pakukhuthala kwa ma pores, kapangidwe ka ma pore, kulowerera ndi mphamvu zamakina za nembanemba yolowa. Kugwiritsa ntchito calcium yolemera yomwe imapangidwa ndi kupukutidwa konyowa ngati "porogen" kumakhala ndi phindu lotsika la kuyamwa mafuta, kufalikira bwino ndi kusuntha bwino, ndipo kungachepetsenso kwambiri kuchuluka kwa utomoni wonyamula, pulasitiki, mafuta ndi zina zowonjezera.

(3) Utoto wa Masterbatch: Utoto wa masterbatch wa mtundu ndi njira yomwe imagwiritsidwa ntchito kwambiri popaka utoto wa pulasitiki pakadali pano, yomwe nthawi zambiri imapangidwa ndi utomoni wonyamula, utoto ndi zowonjezera. Kafukufuku wambiri wasonyeza kuti kugwiritsa ntchito calcium carbonate, wollastonite kapena barium sulfate m'malo mwa utoto wina kuti akonze masterbatch ya utoto kungathandize kufalikira kwa utoto ndikuchepetsa ndalama zopangira popanda kuchepetsa magwiridwe antchito a utoto wa masterbatch ya utoto. Kafukufuku wina wasonyeza kuti masterbatch ya utoto yokonzedwa ndi calcium bicarbonate yonyowa m'malo mwa titanium dioxide, pamene kuchuluka kwa kusintha kuli 20%, mawonekedwe a utoto sasintha, ndipo magwiridwe antchito ndi ofanana kwambiri ndi a utoto woyera, ndi kusiyana pang'ono kwa mitundu.

Monga wopanga wa calcium yolemeramphero yoperamakina,HCQ, HC mndandanda waukulu wa calcium wolemera wa Raymond mill, HLM wolemera calcium coarse ufa wowongokakupukusampherondi zina calcium yolemeramphero yoperaZipangizo zopangidwa ndi HCMilling (Guilin Hongcheng) zakhala zikugwiritsidwa ntchito kwambiri ndipo zapeza mbiri yabwino popanga calcium yonyowa yochuluka kutsogolo kwa front-end. Ngati mukufuna kupanga calcium yochuluka yochuluka ndipo mukufuna zida zopangira mphero yowuma kutsogolo kwa front-end, chonde funsani HCM kuti mudziwe zambiri za zipangizozi.
