Calcined kaolin

Calcined kaolin anachokera ku United States, poyambirira kuchotsa organic carbon phindu mu kaolin zofewa ndi kusintha whiteness mankhwala.Pambuyo pake, anthu anagwiritsa ntchito njira imeneyi pokonza kaolin woyezera malasha, n’kupanga zinthu zogwira ntchito, zapamwamba, ndiponso zamtengo wapatali kuposa kaolin wamba.Kukulitsa kwambiri ntchito zosiyanasiyana za kaolin.Dziko langa lili ndi zinthu zambiri za kaolin zoyezera malasha, ndipo kuwerengetsa ndi njira yofunika kwambiri pa nthaka yoyezera malasha.

Cholinga chachikulu cha kaolin calcination ndi:
1. Chotsani organic carbon ndi mchere wina wosadetsedwa kuti mukhale woyera.
2. Chotsani magulu amadzi ndi hydroxyl a Kaolin kuti muwonjezere voliyumu yopanda kanthu ndi reactivity ya mankhwala a mankhwala opangidwa ndi calcined, kusintha maonekedwe a thupi ndi mankhwala, ndikukwaniritsa zosowa zosiyanasiyana zogwiritsira ntchito.The calcined kaolin amachotsedwa mu kapangidwe kapena madzi crystal, carbon ndi zinthu zina kusakhazikika, ndi kukhala kaolinite, malonda dzina ndi "calcined kaolin".
Calcined kaolin ali ndi ubwino woyera mkulu, kachulukidwe ang'onoang'ono chochuluka, lalikulu enieni pamwamba m'dera ndi pore voliyumu, mayamwidwe bwino mafuta, kuphimba ndi abrasion kukana, ndi kutchinjiriza mkulu, kukana nyengo ndi bata.

Mawonekedwe:
1. Mapangidwe a mankhwala ndi okhazikika, chiwerengero cha molar cha Si02 / Al203 ndi 2/1.
2. Kuyera ndi koyera komanso kosasunthika, kukula kwa tinthu ndi kopitilira muyeso, ndipo kugawa m'lifupi ndi zotsalira za sieve ndizochepa.
3. Maonekedwe a kristalo wonyezimira atha, kubalalitsidwa kuli bwino, mphamvu yophimba ndi yamphamvu, ndipo kuyandama kuli bwino, ndipo sikophweka kugwa.

Kugwiritsa ntchito Calcined Kaolin
1. Calcined kaolin kuti ❖ kuyanika
Kuchuluka kwa ntchito: Mitundu yosiyanasiyana ya zokutira, kuphatikiza utoto wa latex, zokutira zaufa, zokutira zotengera mafuta ndi magawo ena.
Zogulitsa: kuyera kwakukulu, kukula kwa tinthu tating'onoting'ono, kusakhazikika kwamankhwala, luso lophimba kwambiri, madzi abwino komanso kuyandama, mtengo wotsika, ndi zina zambiri, zomwe zimatha kuchepetsa kufunikira kwa utoto wokwera mtengo;kuphatikiza pazikhalidwe zomwe zili pamwambazi, ilinso ndi maubwino osawoneka bwino, mawonekedwe owoneka bwino, kuchuluka kwamafuta amayamwidwe komanso kuchuluka kwa pigment voliyumu, sikophweka kukalamba, kusavala komanso kosavuta kuyimitsa m'madzi kapena sing'anga yamafuta, ndipo ali ndi mphamvu zobisala zapamwamba.Chinthu chofunika kwambiri ndi chakuti akhoza m'malo mtengo titaniyamu woipa, ndipo akhoza kuchepetsa chodabwitsa photocoagulation chifukwa ntchito titaniyamu woipa pamene wosakaniza ndi ntchito;makamaka popanga ma pigment ngati latex, amatha kupanga zokutira kukhala zowoneka bwino komanso kukana dzimbiri.Sinthani kuuma ndi khalidwe la filimu yokutira.

2. Calcined kaolin kwa mphira
Kuchuluka kwa ntchito: mitundu yonse ya zinthu za mphira ndi zinthu zapulasitiki ndi sheath ya chingwe, wosanjikiza chingwe ndi PVC, PE ndi zida zina.
Mankhwala mbali: wololera tinthu kukula kugawa, kapangidwe koyera, otsika zonyansa okhutira, kaolin khumi zili wamkulu kuposa 98%, dispersibility wabwino, tinthu kukula bwino, kuyanjana wabwino ndi mphira ndi pulasitiki, bwino kwambiri pokonza labala ndi pulasitiki.Imakhala ndi inerness yabwino yamankhwala ndipo sichimakhudzana ndi mankhwala kapena ma reagents ena amadzimadzi kutentha, potero imawongolera kukana kwa dzimbiri kwa zinthu zamagetsi;mkulu refractoriness akhoza kusintha matenthedwe denaturation kutentha mankhwala chingwe;Zabwino kwambiri zamagetsi zamagetsi, etc.

3. Calcined kaolin kwa zoumba
Kuchuluka kwa ntchito: zoumba zamagetsi zokwera ndi zotsika, zoumbala zomwe zimagwiritsidwa ntchito tsiku ndi tsiku, zoumba zaukhondo, zoumba zosagwira ndi mankhwala ndi zonyezimira zaukadaulo ndi zamisiri.
Zogulitsa: kuyera kwakukulu, kuyeretsedwa kwakukulu kwamankhwala, kukana kwambiri, dispersibility yabwino ndi fluidity, komanso kulosera kwakukulu Maonekedwe amatha kusinthidwa popanda ming'alu, ndipo mawonekedwewo amatha kusungidwa bwino atachotsa mphamvu yakunja, ndipo ali ndi mapangidwe abwino, kuyanika ndi sintering katundu.Zomwe zimathamangitsidwa zimakhala ndi maonekedwe a mtundu woyera, kugwirizanitsa, mphamvu zamakina apamwamba komanso zokolola zambiri.
