Guilin Hongkaolin vertical mill

Guilin Hongcheng opanga zida zoperaanaphunzira kuti calcined kaolin akupera mankhwala zimagwiritsa ntchito mu ❖ kuyanika makampani, amene ntchito monga filler mu utoto, pa dzanja limodzi amasewera mbali ya thupi kudzazidwa, Komano ali wina youma chophimba mphamvu. Kotero, ndi chiyani cholozera zofunika za calcined kaolin akupera mankhwala?

Zogulitsa za calcined kaolin zokutira makamaka zimaphatikizira kuyera, kukula kwa tinthu, kuphimba mphamvu, kubalalitsidwa, zotsalira za 325 mesh sieve, mayamwidwe amafuta, voliyumu yoyika, mtengo wa pH, kukana kwanyengo ndi zina zotero:

1. Digiri yoyera

whiteness ndiye chizindikiro chachikulu cha calcined kaolin, ndipamwamba kwambiri. Utoto wamtundu umapangidwanso ndi utoto woyera monga utoto wapansi ndi mtundu wa amayi.kuyera kuyenera kukhala kwakukulu kuposa 90%, opanga ena amafunanso kuposa 93%. Kukhazikika kwa digiri yoyera ndikofunikira kwambiri, ngati kusinthasintha kuli kwakukulu kwambiri kuti kungakhudze mawonekedwe a zokutira, zomwe zimapangitsa kusiyana kwamitundu yosiyanasiyana yazinthu zomwe zili munjira yomweyo.

2.Granularity

Tinthu kukula kwenikweni ndi index ya woimira, ❖ kuyanika opanga kawirikawiri mwachindunji kudziwa tinthu kukula. Komabe, chifukwa zizindikiro zina za calcined kaolin ndi mwachindunji zokhudzana ndi tinthu kukula, ngati tinthu kukula si zabwino mokwanira, kapena osayenera, zidzaonekera kudzera zizindikiro zina. Kwa opanga calcined kaolin, index yowunikira ya chomaliza iyenera kukhala-2 μ m pafupifupi 80%. Zoonadi, ntchito ya zinthu zopangidwa ndi zipangizo zosiyanasiyana zidzakhala zosiyana, ndipo ngati zizindikiro zina zili zoyenerera, zofunikira za kukula kwa tinthu zingathenso kuchepetsedwa.

Kukula kwa tinthu kumakhudzidwa makamaka ndi kuvala kwa miyala yaiwisi ndi kutentha kwa calcination. The kuvala luso anatsimikiza ndi khalidwe laiwisi ore, amene makamaka amakhudza tinthu kukula kwa zopangira siteji, ndi kutentha calcination makamaka zimakhudza tinthu kukula kwa ufa pambuyo ng'anjo. Pakuti ❖ kuyanika calcination kaolin, sing'anga kutentha calcination (1000 ~ 1200 ℃), mulingo woyenera calcination kutentha amasankhidwa mu gawo amorphous basi kusintha pakachitsulo zotayidwa spinel gawo, umene umabala porous Kukula dongosolo, chifukwa mu pore chitukuko, ndi abrasion mtengo wa mankhwala ndi otsika.

3.Kuphimba mphamvu

Mphamvu yophimba ndiye chizindikiro chofunikira kwambiri cha calcined kaolin. Ubwino wa ufa, mawonekedwe ochulukirapo omwe amapangidwa mu zokutira, kuwonjezereka kwa mphamvu ndi kuwonetsetsa kwa kuwala, makamaka pamene kukula kwa tinthu kuli kofanana ndi kutalika kwa kuwala kowoneka bwino, kumakhala ndi mphamvu yobalalika kwambiri, ikhoza kutulutsa mphamvu yaikulu yophimba, pamene yocheperapo mtengo uwu, mphamvu yophimba idzakhala yaying'ono chifukwa cha diffraction ya kuwala.

Kwa kaolin yabwino kwambiri, kaya ingathe kumwazikana mu zokutira ndi chinthu chofunikira chomwe chikukhudza mphamvu yake yophimba. Ngakhale calcination imakweza mphamvu yophimba ya kaolin mu zokutira zotengera madzi, sizofunikira. Nthawi zina, zimakhala zosavuta kupukuta ndi kupanga tinthu tating'onoting'ono, koma zimapangitsa kuti mphamvu yophimba ikhale yochepa, ndipo sichitha kugwiritsidwa ntchito popaka konse.

4.Kubalalika

Makampani ❖ kuyanika zoweta anati kubalalitsidwa, ndi lingaliro lomwelo. Ngakhale calcined kaolin wadutsa ultrafine ufa, ndi pafupifupi tinthu kukula 1 μ m kapena zochepa, mu utoto, mu mkulu mamasukidwe akayendedwe kholo mowa, ndi particles si osiyana koma m'magulumagulu. Kukhoza kwa calcined kaolin kumwazikana mu ❖ kuyanika dongosolo amatchedwa kubalalitsidwa. Kubalalika kwa calcined kaolin ndikwabwino. Ngati kalasi yopera ikukwaniritsa zofunikira zomaliza, imatha kumwazikana mkati mwa dongosolo lopaka.

Kubalalitsidwa kwa calcined kaolin kumagwirizana ndi zotsatira zomaliza zakupera. Ngati 45 μ m kapena tinthu tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono timabalalika. Zofunikira pa index iyi ndi zosakwana 45 μ m, ndipo zazing'ono, ndizabwino. Ngati kubalalitsidwa kwa titaniyamu woipa kungafikire 25 μ m, lolingana ndi kalasi akupera ayenera kusankhidwa monga 4 kapena kuposa.

5.325 mesh sieve zotsalira

325 mauna sieve zotsalira ndi index yofunika, chofunika ❖ kuyanika kwa ndondomekoyi ndi <0.02%, ndipo ang'onoang'ono bwino.325 mauna sieve imakhalanso makamaka yokhudzana ndi zotsatira zomaliza akupera, amafuna palibe 45 μ m kapena particles zazikulu pa ultrafine processing. Chinthu chinanso chomwe chimalimbikitsa ndi zonyansa, zosakanikirana ndi zonyansa zimakhala ndi zotsatira zoonekeratu pakuwunika kwa 325 mesh.

6.Oil mayamwidwe mtengo

Mafuta a mayamwidwe a calcined kaolin ndi 50g / 100g ~ 60g / 100g ndi otsika, kuchuluka kwa mayamwidwe amafuta ndikokwera kwambiri, kukhuthala kwa ❖ kuyanika kopangidwa ndi chilinganizo chomwecho ndi chachikulu, kuti muchepetse kukhuthala, kuchuluka kwa utoto wamafuta kuyenera kuonjezera mtengo; mtengo wamayamwidwe wamafuta ndiwotsika kwambiri, zokutira zomwe zimapangidwa ndizosavuta kukhazikika, ndipo kutsegulira kwake sikwabwino. Mafuta mayamwidwe mtengo wa kaolin ndi tinthu kukula kugawa, porosity, enieni pamwamba dera, ndi njere mtundu wa particles. Kukula kwa tinthu tating'onoting'ono, malo enieniwo ndi okulirapo, ndipo mtengo wamayamwidwe wamafuta ndi

7.Volumu yokhazikika

Mafuta a mayamwidwe a calcined kaolin ndi 50g / 100g ~ 60g / 100g ndi otsika, kuchuluka kwa mayamwidwe amafuta ndikokwera kwambiri, kukhuthala kwa ❖ kuyanika kopangidwa ndi chilinganizo chomwecho ndi chachikulu, kuti muchepetse kukhuthala, kuchuluka kwa utoto wamafuta kuyenera kuonjezera mtengo; mtengo wamayamwidwe wamafuta ndiwotsika kwambiri, zokutira zomwe zimapangidwa ndizosavuta kukhazikika, ndipo kutsegulira kwake sikwabwino. Mafuta mayamwidwe mtengo wa kaolin ndi tinthu kukula kugawa, porosity, enieni pamwamba dera, ndi njere mtundu wa particles. Kukula kwa tinthu tating'onoting'ono, malo enieniwo ndi okulirapo, ndipo mayamwidwe amafuta ndi apamwamba.

8.pH mtengo

Phindu la pH limasonyeza asidi ndi alkalinity ya kaolin yosungunuka, ndipo pH iyenera kukhala pakati pa 6 ndi 8, makamaka pafupi ndi ndale. PH ya calcined kaolin palokha siimalowerera, kotero kusintha kwa PH sikofunikira pamakampani okutira.

9.Kukana kwanyengo

Pambuyo popangidwa ndi utoto ndi kupukuta, filimu ya utoto kupyolera mudzuwa ndi mvula, idzasanduka chikasu, kutaya kuwala ndi ufa. Kukhoza kwa ma pigment kukana kusintha kumeneku kumatchedwa kukana kwa nyengo. Calcined kaolin alibe mphamvu mankhwala ntchito pa kuwala, choncho ndi zabwino 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
