Guilin Hongkaolin mira poutū

Guilin Hongcheng nga kaihanga taputapu huriako e calcined kaolin huri hua e te nuinga whakamahia i roto i te ahumahi paninga, e whakamahia ana hei whakakī i roto i te peita, i runga i tetahi ringa te mahi o te whakakī tinana, i runga i te tahi atu i te ringa he etahi kaha hipoki maroke.Na, he aha nga whakaritenga taurangi o nga hua huri kaolin calcined?

Ko nga tohu hua o te kaolin calcined mo te paninga te nuinga ko te ma, te rahi o te matūriki, te kaha hipoki, te whakamararatanga, te toenga tatari 325 mesh, te uara whakauru hinu, te rōrahi waipara, te uara pH, te aukati huarere me era atu:

1.White tohu

Ko te ma ko te tohu tuatahi o te kaolin calcined, te teitei ake te pai.Ko te peita tae ka mahia ano ki te peita ma hei peita turanga me te tae whaea.Me nui ake te ma i te 90%, ko etahi o nga kaihanga me nui ake i te 93%.He mea tino nui te pumau o te tohu ma, mena he nui rawa te rerekee ki te pa ki te mahi whatu o te paninga, ka puta te rereketanga o te tae o nga roopu hua rereke i raro i te tauira kotahi.

2.Granularity

Ko te rahi o te matūriki he tohu tohu, he uaua nga kaihanga whakakikorua ki te kite i te rahi matūriki.Heoi ano, na te mea ko etahi atu tohu o te kaolin calcined e hono tika ana ki te rahi o te matūriki, ki te kore e pai te rahi o te matūriki, ki te kore e tika ranei, ka whakaatuhia ma etahi atu tohu.Mo te kaihanga kaolin calcined, ko te tohu tirotiro o te hua kua oti kia-2 μm mo te 80%.Ko te tikanga, ka rere ke te mahi o nga hua e hangaia ana e nga rauemi mata rereke, a, ki te mea he tohu etahi atu tohu, ka taea hoki te whakaiti i nga whakaritenga rahi matūriki.

Ko te rahi o te matūriki ka pangia e te kakahu o te ore mata me te pāmahana o te calcination.Ko te kaha o te kakahu e whakatauhia ana e te kounga o te ore raw, e pa ana ki te rahi o te matūriki o te atamira mata, me te pāmahana calcination e pa ana ki te rahi o te paura i muri i te oumu.Mo te paninga calcination kaolin, te pāmahana reo calcination (1000 ~ 1200 ℃), ka tohua te pāmahana calcination tino pai i roto i te waahanga amorphous ka huri noa ki te waahanga konumohe konumohe spinel, e whakaputa ana i te hanganga roha porous, ka puta te whanaketanga pore, me te uara abrasion o te he iti te hua.

3.Te kaha hipoki

Ko te mana hipoki te tohu tino nui o te kaolin calcined.Ko te pai ake o te paura, ko te nui ake o te atanga i hangaia i roto i te paninga, ka kaha ake te hurihanga me te whakaata o te marama, ina koa ka rite te rahi o te matūriki ki te roangaru o te marama e kitea ana, he kaha te kaha o te marara, ka taea te whakaputa i te kaha hipoki nui rawa atu, ka iti ake i tenei uara, ka iti ake te kaha o te uhi na te rereketanga o te marama.

Mo te kaolin tino pai, ahakoa ka taea te marara katoa i roto i te paninga he take nui ano e pa ana ki tona mana hipoki.Ahakoa ka whakapai ake te calcination i te mana hipoki o te kaolin i roto i te paninga wai, ehara i te mea nui.I etahi wa, he ngawari ki te tarai me te hanga i nga matūriki matotoru, engari ka whakahekehia te kaha o te uhi, kaore e taea te whakamahi mo te paninga katoa. Ko tetahi atu raruraru ko te calcination i raro i te 1000 ℃ i etahi wa ka puta he waahanga whero marama, he tino kino. mo nga poaka ma.1050 ℃ me te paura tino pai.

4.Disperssiveness

Ko te ahumahi whakakikorua whare i kii te whakamararatanga, a he rite tonu te kaupapa.Ahakoa ko te kaolin calcined kua pau te paura ultrafine, me te rahi o te matūriki toharite o te 1 μ m iti iho ranei, i roto i te peita, i roto i te waipiro matua viscosity teitei, karekau nga matūriki i wehe engari kua whakarōpūhia.Ko te kaha o te kaolin calcined ki te marara i roto i te punaha paninga ka kiia ko te marara.He pai te marara o te kaolin calcined.Mena ka tutuki te karaehe huri ki nga whakaritenga whakamutunga, ka taea te marara ki roto i te punaha whakakikorua.

Ko te marara o te kaolin calcined e pa ana ki te hua whakamutunga o te huri.Mena kei roto i te 45 μm nga matūriki nui atu ranei i roto i te tukanga tukatuka superfine, e kore e marara i roto i te punaha paninga.Ko te whakaritenga mo tenei taurangi he iti iho i te 45 μm, me te iti ake, ka pai ake.Mena ka taea e te marara o te titanium dioxide te tae ki te 25 μm, kia rite ki te tohu hurihanga kia 4 neke atu ranei.

5.325 mata tatari toenga

Ko te toenga tatari mata 325 he tohu nui, ko te whakaritenga o te paninga ki tenei taurangi he <0.02%, me te iti ake te pai ake.325 mesh sieve te nuinga e pa ana ki te hua whakamutunga o te huri, kaore e hiahiatia he 45 μm nui atu ranei i te waa. tukatuka ultrafine.Ko tetahi atu take whakaawe he poke, i konatunatua ki nga poke ka tino kitea te paanga ki te ihirangi tirotiro o te mata 325.

6.Oil absorption uara

Ko te uara whakauru hinu o te kaolin calcined he 50g / 100g ~ 60g / 100g he ngawari, he nui rawa te nui o te whakauru hinu, he nui te paninga paninga i hangaia me te tauira kotahi, hei whakaiti i te pokey, me te nui o te turanga peita. whakanui i te utu;he iti rawa te uara whakauru hinu, he ngawari ki te whakatau i te paninga i hangaia, kaore i te pai te mahi whakatuwhera.Ko te uara whakauru hinu o te kaolin ko te tohatoha rahi matūriki, te porosity, te waahanga mata motuhake, me te momo witi o nga matūriki.He iti te rahi o te matūriki, he nui ake te waahanga mata motuhake, me te uara whakauru hinu

7.Rarahi whakataunga

Ko te uara whakauru hinu o te kaolin calcined he 50g / 100g ~ 60g / 100g he ngawari, he nui rawa te nui o te whakauru hinu, he nui te paninga paninga i hangaia me te tauira kotahi, hei whakaiti i te pokey, me te nui o te turanga peita. whakanui i te utu;he iti rawa te uara whakauru hinu, he ngawari ki te whakatau i te paninga i hangaia, kaore i te pai te mahi whakatuwhera.Ko te uara whakauru hinu o te kaolin ko te tohatoha rahi matūriki, te porosity, te waahanga mata motuhake, me te momo witi o nga matūriki.He iti te rahi o te matūriki, he nui ake te waahanga mata motuhake, he nui ake te uara whakauru hinu.

8.pH uara

Ko te uara pH e whakaatu ana i te waikawa me te kawakore o te kaolin calcined, me te uara pH kei waenganui i te 6 me te 8, he tata ki te koretake.Ko te PH o te kaolin calcined ake he koretake, na reira kaore e hiahiatia te whakarereketanga PH i roto i te umanga whakakikorua.

9.Weather resistance

I muri i te hanga o te poaka ki te peita me te pania, ka huri te kiriata peita i te ra me te ua, ka kowhai, ka ngaro te marama me te paura.Ko te kaha o nga poaka ki te aukati i enei huringa ka kiia ko te aukati huarere.Karekau he mahi matū kaha o te kaolin ki runga i te marama, no reira he pai te parenga huarere.

10.Ko etahi atu tohu

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
