He aha nā koi kuhikuhi o ka kaolin calcined i hoʻohana ʻia no ka hana ʻana i nā huahana uhi?

ʻO Guilin Hongcheng nā mea hana wiliUa aʻo ʻia ʻo ka calcined kaolin wili nā huahana i hoʻohana nui ʻia i ka ʻoihana uhi, i hoʻohana ʻia e like me ka hoʻopiha piha ʻana i ka pena, ma kekahi ʻaoʻao e pāʻani ana i ke ʻano o ka hoʻopiha kino ʻana, ma ka ʻaoʻao ʻē aʻe he ikaika uhi maloʻo.No laila, he aha nā koi kuhikuhi o nā huahana wili kaolin calcined?

ʻO nā huaʻōlelo huaʻōlelo o ka kaolin calcined no ka uhi ʻana he keʻokeʻo, ka nui o ka nui, ka uhi ʻana i ka ikaika, ka hoʻopuehu, 325 mesh sieve koena, waiwai absorption ʻaila, ka nui deposition, ka waiwai pH, ke kū ʻana o ka wā a pēlā aku:

1.White degere

ʻO ke keʻokeʻo ka papa kuhikuhi mua o ka kaolin calcined, ʻoi aku ka kiʻekiʻe.Hana ʻia ka pena kala me ka pena keʻokeʻo e like me ka pena kumu a me ka kala mother.whiteness ma ka liʻiliʻi loa ma mua o 90%, ʻoi aku ka nui o nā mea hana ma mua o 93%.He mea koʻikoʻi ke kūpaʻa degere keʻokeʻo, inā ʻoi aku ka nui o ka fluctuation e hoʻopilikia i ka hana optical o ka uhi ʻana, e hopena i ka ʻokoʻa kala o nā ʻāpana like ʻole o nā huahana ma lalo o ke ʻano like.

2.Granularity

ʻO ka nui o ka ʻāpana he mea kuhikuhi o ka hōʻike ʻana, ʻaʻole hiki i nā mea hana uhi ke ʻike pololei i ka nui o ka ʻāpana.Eia naʻe, no ka mea, pili pono nā hōʻailona ʻē aʻe o ka kaolin calcined i ka nui o ka particle, inā ʻaʻole maikaʻi ka nui a i ʻole kūpono ʻole, e ʻike ʻia ia ma o nā hōʻailona ʻē aʻe.No ka mea hana kaolin calcined, ʻo ka helu nānā ʻana o ka huahana i hoʻopau ʻia he-2 μm ma kahi o 80%.ʻO kaʻoiaʻiʻo, ʻokoʻa ka hana o nā huahana i hana ʻia e nā mea maka, a inā kūpono nā mea hōʻailona ʻē aʻe, hiki ke hoʻemi ʻia nā koi nui o ka particle.

Hoʻopili nui ʻia ka nui o ka ʻāpana e ka ʻaʻahu ʻana o ka ʻaila maka a me ka mahana o ka calcination.Hoʻoholo ʻia ka hiki ke hoʻopaʻa ʻia e ka maikaʻi o ka ʻaila maka, ka mea nui e pili ana i ka nui o ka nui o ka pae maka, a ʻo ka mahana calcination e pili nui i ka nui o ka pauka ma hope o ke kiln.No ka uhi ʻana i ka calcination kaolin, ka wela wela calcination (1000 ~ 1200 ℃), ua koho ʻia ka mahana calcination maikaʻi loa i ka manawa amorphous i hoʻololi ʻia i loko o ka silicon alumina spinel phase, ka mea e hoʻohua ai i ka hoʻonui ʻana o ka porous, ka hopena i ka ulu ʻana o ka pore, a me ka waiwai abrasion o ka ʻano haʻahaʻa ka huahana.

3.Ka ikaika uhi

ʻO ka mana uhi ka papa kuhikuhi nui loa o ka kaolin calcined.ʻO ka ʻoi aku ka maikaʻi o ka pauka, ʻoi aku ka maikaʻi o ka hoʻopili ʻana i ka uhi, ʻoi aku ka ikaika o ka refraction a me ka noʻonoʻo ʻana o ka mālamalama, ʻoi aku ka nui o ka nui o ka ʻāpana me ka lōʻihi o ka nalu o ke kukui ʻike ʻia, ʻoi aku ka ikaika o ka hoʻopuehu ʻana, hiki ke hana i ka ikaika uhi nui loa. ke emi iho i keia waiwai, e emi mai ana ka ikaika o ka uhi no ka like ole o ka malamalama.

No ka kaolin maikaʻi loa, inā hiki ke hoʻopuehu piha ʻia i loko o ka uhi ʻana he mea nui hoʻi ia e pili ana i kona mana uhi.ʻOiai hoʻomaikaʻi ka calcination i ka mana uhi o kaolin i ka uhi wai, ʻaʻole ia he mea nui.I kekahi mau hihia, maʻalahi ka sintering a hana i nā ʻāpana koʻikoʻi, akā e hoʻemi ana ka ikaika o ka uhi ʻana, ʻaʻole hiki ke hoʻohana ʻia no ka uhi ʻana. no nā puaʻa keʻokeʻo.1050 ℃ a me ka pauka superfine.

4.Disperssiveness

Ua ʻōlelo ka ʻoihana hoʻoheheʻe kūloko i ka hoʻopuehu, a ua like ka manaʻo.ʻOiai ua loaʻa i ka kaolin calcined ka pauka ultrafine, me ka nui o ka nui o ka 1 μm a i ʻole ka liʻiliʻi, i loko o ka pena, i loko o ka waiʻona makua viscosity kiʻekiʻe, ʻaʻole kaʻawale nā ʻāpana akā hui pū ʻia.ʻO ka hiki o ka kaolin calcined e hoʻopuehu i loko o kahi ʻōnaehana uhi i kapa ʻia ʻo dispersion.Maikaʻi ka hoʻopuehu ʻana o ka kaolin calcined.Inā hoʻokō ka papa wili i nā koi hope, hiki ke hoʻopuehu ʻia i loko o ka ʻōnaehana uhi.

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

5.325 mesh sieve koena

ʻO ka 325 mesh sieve koena he kuhikuhi koʻikoʻi, ʻo ke koi o ka uhi ʻana i kēia kuhikuhi he <0.02%, a ʻo ka liʻiliʻi ʻoi aku ka maikaʻi.325 mesh sieve pili pū kekahi i ka hopena hope o ka wili ʻana, ʻaʻole koi ʻia ʻo 45 μm a i ʻole nā mea nui i ka wā. ka hana ʻana ultrafine.ʻO kekahi kumu hoʻohālikelike he haumia, hui pū ʻia me nā haumia i ka hopena ʻike loa i ka ʻike screening o 325 mesh.

6.Oil absorption waiwai

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

7.Settlement volume

8.pH waiwai

Hōʻike ka pH waiwai i ka waika a me ka alkalinity o ka kaolin calcined, a ʻo ka waiwai pH ma waena o 6 a me 8, kokoke loa i ka neutral.ʻO ka PH o ka kaolin calcined ponoʻī he kūʻokoʻa, no laila ʻaʻole koi ʻia ka hoʻololi PH i ka ʻoihana uhi.

9.Weather kū'ē

Ma hope o ka hana ʻia ʻana o ka puaʻa me ka pena a me ka daub, ʻo ke kiʻi pena ma o ka lā a me ka ua, e huli melemele, nalowale ka mālamalama a me ka pauka.ʻO ka hiki o nā pigments ke kū'ē i kēia mau hoʻololi i kapaʻia ke kū'ē i ka wā.ʻAʻohe hana kemika ikaika i ka kaolin calcined ma ka mālamalama, no laila he kūʻē maikaʻi i ka wā.

10. Nā hōʻailona'ē 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
