ʻO Guilin Hongkaolin wili kū pololei

Nā mea hana lako wili ʻo Guilin Hongchengua aʻo ʻia ua hoʻohana nui ʻia nā huahana wili kaolin calcined i ka ʻoihana uhi, kahi i hoʻohana ʻia ma ke ʻano he mea hoʻopihapiha i ka pena, ma kekahi ʻaoʻao e pāʻani ana i ke kuleana o ka hoʻopiha kino, ma ka ʻaoʻao ʻē aʻe he mana uhi maloʻo. No laila, he aha nā koi kuhikuhi o nā huahana wili kaolin calcined?

ʻO nā ʻōkuhi huahana o ke kaolin calcined no ka uhi ʻana e komo pū me ke keʻokeʻo, ka nui o ka ʻāpana, ka ikaika uhi, ka hoʻopuehu ʻana, ke koena sieve 325 mesh, ka waiwai omo aila, ka nui o ka waiho ʻana, ka waiwai pH, ke kū'ē ʻana i ka wā a pēlā aku:

1. Kekelē keʻokeʻo

ʻO ke keʻokeʻo ka helu kumu o ke kaolin calcined, ʻoi aku ke kiʻekiʻe o ka maikaʻi. Hana ʻia ka pena kala me ka pena keʻokeʻo ma ke ʻano he pena kumu a me ke kala makuahine. Pono ke keʻokeʻo ma ka liʻiliʻi ma mua o 90%, koi kekahi mau mea hana ma mua o 93%. He mea nui loa ke kūpaʻa keʻokeʻo, inā nui loa ka fluctuation e hoʻopilikia i ka hana optical o ka uhi ʻana, e hopena ana i ka ʻokoʻa kala o nā ʻāpana like ʻole o nā huahana ma lalo o ke ʻano like.

2. Ka nui o ka ʻili

ʻO ka nui o nā ʻāpana he ʻōkuhi o ka hōʻike ʻana, ʻaʻole pinepine nā mea hana uhi e ʻike pololei i ka nui o nā ʻāpana. Eia nō naʻe, no ka mea, pili pono nā ʻōkuhi ʻē aʻe o ke kaolin calcined i ka nui o nā ʻāpana, inā ʻaʻole lawa ka maikaʻi o ka nui o nā ʻāpana, a i ʻole kūpono ʻole, e hōʻike ʻia ma o nā ʻōkuhi ʻē aʻe. No ka mea hana kaolin calcined, pono e -2 μm ka ʻōkuhi nānā o ka huahana i hoʻopau ʻia ma kahi o 80%. ʻOiaʻiʻo, e ʻokoʻa ka hana o nā huahana i hana ʻia e nā mea maka like ʻole, a inā kūpono nā ʻōkuhi ʻē aʻe, hiki ke hoʻemi ʻia nā koi nui o nā ʻāpana.

ʻO ka nui o ka ʻāpana e pili nui ʻia e ke komo ʻana o ka ʻai maka a me ka mahana o ka calcination. Hoʻoholo ʻia ka hiki ke komo e ka maikaʻi o ka ʻai maka, ka mea e pili nui ana i ka nui o ka ʻāpana o ke kahua o ka mea maka, a ʻo ka mahana calcination e pili nui ana i ka nui o ka ʻāpana o ka pauka ma hope o ka umu. No ka uhi ʻana i ka calcination kaolin, ka calcination mahana waena (1000 ~ 1200 ℃), ua koho ʻia ka mahana calcination kūpono i ka pae amorphous i hoʻololi ʻia i ka pae spinel alumini silicon, kahi e hana ai i ka hoʻonui porous, e hopena ana i ka ulu ʻana o ka pore, a he haʻahaʻa ka waiwai abrasion o ka huahana.

3. Ka ikaika uhi

ʻO ka mana uhi ka helu koʻikoʻi loa o ke kaolin calcined. ʻO ka ʻoi aku ka maikaʻi o ka pauka, ʻoi aku ka nui o ka interface i hana ʻia i loko o ka uhi ʻana, ʻoi aku ka ikaika o ka refraction a me ka reflection o ke kukui, ʻoiai ke like ka nui o ka ʻāpana me ka nalu o ke kukui ʻike ʻia, loaʻa iā ia ka hopena hoʻopuehu ikaika loa, hiki ke hana i ka ikaika uhi nui loa, i ka wā emi ma mua o kēia waiwai, e liʻiliʻi ka ikaika uhi ma muli o ka diffraction o ke kukui.

No ke kaolin lahilahi loa, inā hiki ke hoʻopuehu piha ʻia i loko o ka uhi ʻana he mea nui nō hoʻi ia e pili ana i kona mana uhi. ʻOiai ʻo ka calcination e hoʻomaikaʻi i ka mana uhi o kaolin i loko o ka uhi wai, ʻaʻole ia he mea nui. I kekahi mau hihia, maʻalahi ka sintering a hana i nā ʻāpana coarse, akā e hoʻemi ana i ka ikaika uhi, a ʻaʻole hiki ke hoʻohana ʻia no ka uhi ʻana. ʻO kekahi pilikia, ʻo ka calcination ma lalo o 1000 ℃ i kekahi manawa e hana i kahi ʻulaʻula māmā, he mea maikaʻi ʻole ia no nā pigments keʻokeʻo. 1050 ℃ a me ka pauka superfine.

4. Hoʻolaha

Ua ʻōlelo ka ʻoihana uhi kūloko i ka hoʻopuehu ʻana, a ua like ke kumumanaʻo. ʻOiai ua hana ʻia ka pauka ultrafine o ke kaolin calcined, me ka awelika o ka nui o nā ʻāpana he 1 μ m a i ʻole ka liʻiliʻi, i loko o ka pena, i loko o ka waiʻona makua viscosity kiʻekiʻe, ʻaʻole i kaʻawale nā ​​​​ʻāpana akā ua hui pū ʻia. ʻO ka hiki o ke kaolin calcined ke hoʻopuehu i loko o kahi ʻōnaehana uhi ua kapa ʻia ʻo ka hoʻopuehu ʻana. Maikaʻi ka hoʻopuehu ʻana o ke kaolin calcined. Inā kū ka papa wili i nā koi hope loa, hiki ke hoʻopuehu ʻia i loko o ka ʻōnaehana uhi.

ʻO ka hoʻopuehu ʻana o ke kaolin calcined e pili ana i ka hopena hope loa o ka wili ʻana. Inā he 45 μm a ʻoi aku paha nā ʻāpana nui i loko o ke kaʻina hana superfine, ʻaʻole ia e hoʻopuehu ʻia i loko o ka ʻōnaehana uhi. ʻO ke koi no kēia helu kuhikuhi he emi ma mua o 45 μm, a ʻo ka liʻiliʻi, ʻoi aku ka maikaʻi. Inā hiki i ka hoʻopuehu ʻana o ka titanium dioxide ke hiki i 25 μm, e pili ana i ka papa wili e koho ʻia he 4 a ʻoi aku paha.

5.325 mesh kānana koena

ʻO ke koena sieve 325 mesh kahi helu koʻikoʻi, ʻo ke koi o ka uhi ʻana i kēia helu he <0.02%, a ʻo ka liʻiliʻi ka maikaʻi. Pili nui ka sieve 325 mesh i ka hopena hope loa o ka wili ʻana, ʻaʻole pono he 45 μm a i ʻole nā ​​​​​​ʻāpana nui aʻe i ka wā o ka hana ultrafine. ʻO kekahi mea hoʻohuli i ka haumia, i hui pū ʻia me nā haumia i loaʻa ka hopena maopopo loa i ka ʻike kānana o 325 mesh.

6. Ka waiwai omo ʻaila

ʻO ke kumukūʻai omo ʻaila o ke kaolin calcined he 50g / 100g ~ 60g / 100g he kūpono, kiʻekiʻe loa ka nui o ka omo ʻaila, nui ka mānoanoa o ka uhi i hana ʻia me ke ʻano like, i mea e hōʻemi ai i ka mānoanoa, pono e hoʻonui ke kumukūʻai i ka nui o ke kumu pena; haʻahaʻa loa ka waiwai omo ʻaila, maʻalahi ka hoʻonā ʻana i ka uhi i hana ʻia, a ʻaʻole maikaʻi ka hana wehe. ʻO ke kumukūʻai omo ʻaila o ke kaolin ka hoʻolaha ʻana o ka nui o ka ʻāpana, ka porosity, ka ʻili kikoʻī, a me ke ʻano palaoa o nā ʻāpana. He liʻiliʻi ka nui o ka ʻāpana, ʻoi aku ka nui o ka ʻili kikoʻī, a ʻo ke kumukūʻai omo ʻaila

7. Ka nui o ka hoʻoponopono ʻana

ʻO ke kumukūʻai omo ʻaila o ke kaolin calcined he 50g / 100g ~ 60g / 100g he kūpono, kiʻekiʻe loa ka nui o ka omo ʻaila, nui ka mānoanoa o ka uhi i hana ʻia me ke ʻano like, i mea e hōʻemi ai i ka mānoanoa, pono e hoʻonui ke kumukūʻai i ka nui o ke kumu pena; haʻahaʻa loa ka waiwai omo ʻaila, maʻalahi ka hoʻonā ʻana i ka uhi i hana ʻia, a ʻaʻole maikaʻi ka hana wehe. ʻO ke kumukūʻai omo ʻaila o ke kaolin ka hoʻolaha ʻana o ka nui o ka ʻāpana, ka porosity, ka ʻili kikoʻī, a me ke ʻano palaoa o nā ʻāpana. He liʻiliʻi ka nui o ka ʻāpana, ʻoi aku ka nui o ka ʻili kikoʻī, a ʻoi aku ke kiʻekiʻe o ka waiwai omo ʻaila.

8. ka waiwai pH

Hōʻike ka waiwai pH i ka waikawa a me ka alkalinity o ke kaolin calcined, a pono ka waiwai pH ma waena o 6 a me 8, kokoke i ka neutral. ʻO ka PH o ke kaolin calcined ponoʻī he neutral, no laila ʻaʻole koi ʻia ka hoʻololi ʻana o ka PH i ka ʻoihana uhi.

9. Ke kū'ē ʻana i ka wā

Ma hope o ka hana ʻia ʻana o ka pigment me ka pena a me ka daub, e melemele ka ʻili pena ma o ka lā a me ka ua, e nalowale ke kukui a me ka pauka. ʻO ka hiki o nā pigment ke kūʻē i kēia mau loli ua kapa ʻia ʻo ke kūʻē ʻana i ke aniau. ʻAʻohe hana kemika ikaika o ke kaolin calcined ma ka mālamalama, no laila he kūʻē maikaʻi kona i ke aniau.

10. Nā hōʻailona ʻē aʻe

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
