Guilin Hongkaolin vertical mill

Opanga zida zopukutira a Guilin HongchengNdinaphunzira kuti zinthu zopangira kugaya kaolin zokhala ndi calcium zimagwiritsidwa ntchito makamaka mumakampani opanga utoto, zomwe zimagwiritsidwa ntchito ngati chodzaza utoto, mbali imodzi imagwira ntchito yodzaza thupi, mbali inayo imakhala ndi mphamvu yophimba youma. Ndiye, kodi zofunikira za zinthu zopangira kugaya kaolin zokhala ndi calcium ndi ziti?

Ma index a kaolin wothira calcium makamaka amaphatikizapo kuyera, kukula kwa tinthu tating'onoting'ono, mphamvu yophimba, kufalikira, zotsalira za sieve ya 325 mesh, mtengo woyamwa mafuta, kuchuluka kwa malo osungira, pH, kukana kwa nyengo ndi zina zotero:

1. Digiri yoyera

Kuyera ndiye chizindikiro chachikulu cha kaolin yokhala ndi calcium, kukwera kumakhala bwino. Utoto wa utoto umapangidwanso ndi utoto woyera ngati utoto woyambira komanso mtundu wa mayi. Kuyera kuyenera kukhala kopitilira 90%, opanga ena amafunikiranso kupitirira 93%. Kukhazikika kwa digiri yoyera ndikofunikira kwambiri, ngati kusinthasintha kuli kwakukulu kwambiri kuti kusokoneze magwiridwe antchito a kuwala kwa utoto, zomwe zimapangitsa kuti mitundu yosiyanasiyana ya zinthu ikhale yosiyana pogwiritsa ntchito njira yomweyo.

2. Kuchuluka kwa granularity

Kukula kwa tinthu tating'onoting'ono kwenikweni ndi chizindikiro cha kuyimira, opanga utoto nthawi zambiri sadziwa mwachindunji kukula kwa tinthu tating'onoting'ono. Komabe, chifukwa zizindikiro zina za kaolin yokhala ndi calcium zimagwirizana mwachindunji ndi kukula kwa tinthu tating'onoting'ono, ngati kukula kwa tinthu tating'onoting'ono sikuli kokwanira, kapena kosakwanira, kudzawonetsedwa kudzera mu zizindikiro zina. Kwa wopanga kaolin yokhala ndi calcium, chizindikiro chowunikira cha chinthu chomalizidwa chiyenera kukhala -2 μ m pafupifupi 80%. Zachidziwikire, magwiridwe antchito a zinthu zopangidwa ndi zinthu zosiyanasiyana adzakhala osiyana, ndipo ngati zizindikiro zina zili zoyenerera, zofunikira za kukula kwa tinthu tating'onoting'ono zingachepetsedwenso.

Kukula kwa tinthu kumakhudzidwa kwambiri ndi kuwonongeka kwa miyala yaiwisi komanso kutentha kwa calcination. Mphamvu ya calcination imatsimikiziridwa ndi mtundu wa miyala yaiwisi, zomwe zimakhudza kwambiri kukula kwa tinthu tating'onoting'ono ta siteji ya zopangira, ndipo kutentha kwa calcination kumakhudza kwambiri kukula kwa tinthu ta ufa pambuyo pa uvuni. Pa calcination ya kaolin, calcination yapakati pa kutentha (1000 ~ 1200℃), kutentha kwabwino kwa calcination kumasankhidwa mu gawo losasinthika lomwe lasinthidwa kukhala gawo la spinel la silicon aluminiyamu, lomwe limapanga kapangidwe kokulirapo ka ma porous, zomwe zimapangitsa kuti ma pore apangidwe, ndipo mtengo wa abrasion wa chinthucho ndi wotsika.

3. Mphamvu yophimba

Mphamvu yophimba ndiye chizindikiro chofunikira kwambiri cha kaolin yokhala ndi calcium. Ufa ukakhala wofewa, mawonekedwe ake amapangidwa kwambiri, kupendekera ndi kuwunikira kwa kuwala kumakhala kolimba, makamaka pamene kukula kwa tinthu tating'onoting'ono kuli kofanana ndi kutalika kwa kuwala kooneka, kumakhala ndi mphamvu yofalikira kwambiri, kumatha kupanga mphamvu yayikulu yophimba, pomwe mphamvu yophimba imakhala yochepa kuposa iyi, chifukwa cha kufalikira kwa kuwala.

Pa kaolin yopyapyala kwambiri, kaya ingafalikire mokwanira mu utoto ndi chinthu chofunikira chomwe chimakhudza mphamvu yake yophimba. Ngakhale kuti calcination imawonjezera mphamvu yophimba ya kaolin mu utoto wopangidwa ndi madzi, sizofunikira kwenikweni. Nthawi zina, zimakhala zosavuta kuwotcha ndikupanga tinthu tating'onoting'ono, koma zimapangitsa kuti mphamvu yophimba ichepe, ndipo singagwiritsidwe ntchito pophimba konse. Vuto lina ndilakuti calcination yochepera 1000℃ nthawi zina imapanga gawo lofiira lopepuka, lomwe ndi loipa kwambiri pa utoto woyera. 1050℃ ndi ufa wabwino kwambiri.

4. Kufalikira

Makampani opanga utoto wakunyumba adati kufalikira, ndipo lingaliro lake ndi lomwelo. Ngakhale kuti kaolin yokhala ndi calcium yadutsa ufa wa ultrafine, wokhala ndi tinthu tating'onoting'ono ta 1 μ m kapena kuchepera, mu utoto, mu mowa wokhuthala kwambiri, tinthu tating'onoting'ono sitisiyana koma timasonkhana pamodzi. Kuthekera kwa kaolin yokhala ndi calcium kufalikira mu dongosolo lophimba kumatchedwa kufalikira. Kufalikira kwa kaolin yokhala ndi calcium ndikwabwino. Ngati kalasi yopera ikukwaniritsa zofunikira zomaliza, ikhoza kufalikira mkati mwa dongosolo lophimba.

Kufalikira kwa kaolin yokhala ndi calcium kumagwirizana ndi zotsatira zomaliza za kupukutira. Ngati tinthu tating'onoting'ono ta 45 μ m kapena tokulirapo tili mu njira yopangira zinthu zabwino kwambiri, sitidzafalikira mu dongosolo lopaka utoto. Chofunikira cha index iyi ndi chochepera 45 μ m, ndipo chocheperako, chimakhala bwino. Ngati kufalikira kwa titanium dioxide kungafike 25 μ m, kofanana ndi kalasi yopukutira kuyenera kusankhidwa ngati 4 kapena kuposerapo.

Zotsalira za sieve ya mauna 5.325

Chotsalira cha sieve ya maukonde a 325 ndi chizindikiro chofunikira, chofunikira pakuphimba chizindikirochi ndi <0.02%, ndipo chikakhala chaching'ono chimakhala chabwino. Sieve ya maukonde a 325 imagwirizananso kwambiri ndi zotsatira zomaliza za kupera, zomwe sizimafuna 45 μ m kapena tinthu tating'onoting'ono kwambiri panthawi yokonza zinthu zabwino kwambiri. Chinthu china chomwe chimakhudza kwambiri ndi zinyalala, zosakanikirana ndi zinyalala zimakhudza kwambiri kuchuluka kwa maukonde a 325.

6. Kufunika kwa kuyamwa kwa mafuta

Kuchuluka kwa mafuta omwe amayamwa mu kaolin yokhala ndi calcium ndi 50g / 100g ~ 60g / 100g ndi kocheperako, kuchuluka kwa mafuta omwe amayamwa ndi kokwera kwambiri, kukhuthala kwa utoto komwe kumapangidwa ndi njira yomweyo ndi kwakukulu, kuti kuchepetse kukhuthala, kuchuluka kwa utoto woyambira kuyenera kukweza mtengo; kukhuthala kwa mafuta ndi kotsika kwambiri, kukhuthala komwe kumapangidwa ndikosavuta kukhazikika, ndipo magwiridwe antchito otseguka siabwino. Kuchuluka kwa mafuta omwe amayamwa mu kaolin ndi kufalikira kwa tinthu tating'onoting'ono, kufalikira kwa pores, malo enaake, ndi mtundu wa tinthu tating'onoting'ono. Kukula kwa tinthu tating'onoting'ono ndi kochepa, malo enieniwo ndi akulu, ndipo kukhuthala kwa mafuta ndi

7. Kuchuluka kwa ndalama zogulira

Kuchuluka kwa mafuta omwe amayamwa mu kaolin yokhala ndi calcium ndi 50g / 100g ~ 60g / 100g ndi kocheperako, kuchuluka kwa mafuta omwe amayamwa ndi kokwera kwambiri, kukhuthala kwa utoto komwe kumapangidwa ndi njira yomweyo ndi kwakukulu, kuti kuchepetse kukhuthala, kuchuluka kwa utoto woyambira kuyenera kukweza mtengo; kukhuthala kwa mafuta ndi kotsika kwambiri, kukhuthala komwe kumapangidwa ndikosavuta kukhazikika, ndipo magwiridwe antchito otseguka si abwino. Kuchuluka kwa mafuta omwe amayamwa mu kaolin ndi kufalikira kwa tinthu tating'onoting'ono, kufalikira kwa pores, malo enaake, ndi mtundu wa tinthu tating'onoting'ono. Kukula kwa tinthu tating'onoting'ono ndi kochepa, malo enieniwo ndi akulu, ndipo kukhuthala kwa mafuta ndi kwakukulu.

Mtengo wa 8.pH

Mtengo wa pH umasonyeza asidi ndi alkalinity ya kaolin yokhala ndi calcium, ndipo mtengo wa pH uyenera kukhala pakati pa 6 ndi 8, pafupifupi pafupifupi neutral. PH ya kaolin yokhala ndi calcium yokha ndi neutral, kotero kusintha kwa PH sikofunikira mumakampani opanga utoto.

9. Kukana kwa nyengo

Utoto ukapangidwa ndi utoto ndi kupaka utoto, utotowo umasanduka wachikasu, umataya kuwala ndi ufa. Mphamvu ya utoto yolimbana ndi kusinthaku imatchedwa kukana nyengo. Kaolin yokhala ndi calcium ilibe mphamvu yamphamvu ya mankhwala pa kuwala, kotero imakhala ndi kukana nyengo.

10. Zizindikiro zina

ther index requirements for calcined kaolin, acid and alkali resistance, mixing performance, wet performance, density, etc., these are the common characteristics of all calcined kaolin, some are not digital indicators. It is worth paying attention to that, no matter which index of kaolin, the stability of the index is the most important, if the fluctuation is too big, it will bring bad influence to the paint users, affect the overall performance of the paint. As the production equipment of calcined kaolin mill products, it has an important influence on the whiteness, particle size and 325 mesh residue of calcinined kaolin mill products. Guilin Hongcheng grinding equipment can be ground kaolin to 80-2500 mesh for the production of coating, grinding equipment with high output, low energy consumption, consulting equipment price can contact the email:mkt@hcmilling.com
