Guilin Hongkaolin leloala la thipa

Guilin Hongcheng baetsi ba lisebelisoa tsa ho silao ile a ithuta hore lihlahisoa tsa ho sila kaolin calcined li sebelisoa haholo-holo indastering ea ho roala, e sebelisoang e le ho tlatsa pente, ka lehlakoreng le leng e phetha karolo ea ho tlatsa 'mele, ka lehlakoreng le leng e na le matla a itseng a omileng a koahelang.Joale, litlhoko tsa index tsa lihlahisoa tse silang tsa kaolin ke life?

Li-index tsa sehlahisoa tsa kaolin e calcined bakeng sa ho roala haholo-holo li kenyelletsa bosoeu, boholo ba karoloana, matla a koahelang, ho hasana, masala a 325 mesh sieve, boleng ba ho monya oli, bophahamo ba molumo, boleng ba pH, ho hanyetsa boemo ba leholimo joalo-joalo:

1.Tekanyo e tšoeu

bosoeu ke index e ka sehloohong ea calcined kaolin, e phahameng e molemo.Pente ea 'mala e boetse e entsoe ka pente e tšoeu e le pente ea motheo le' mè oa 'mala. bosoeu bo lokela ho ba bonyane ho feta 90%, bahlahisi ba bang ba bile ba hloka ho feta 93%.Botsitso ba degree e tšoeu bo bohlokoa haholo, haeba ho feto-fetoha ho hoholo hoo ho ka amang ts'ebetso ea optical ea ho roala, e bakang phapang ea mebala ea lihlahisoa tse fapaneng tlasa foromo e tšoanang.

2.Granularity

Boholo ba likaroloana ha e le hantle ke index ea boemeli, baetsi ba ho roala ka seoelo ka ho toba ho lemoha boholo ba likaroloana.Leha ho le joalo, hobane litsupa tse ling tsa calcined kaolin li amana ka ho toba le boholo ba karoloana, haeba boholo ba phatsa ha bo botle ka ho lekaneng, kapa bo sa tšoanelehe, bo tla bonahala ka lipontšo tse ling.Bakeng sa moetsi oa kaolin ea calcined, index ea tlhahlobo ea sehlahisoa se phethiloeng e lokela ho ba-2 μ m hoo e ka bang 80%.Ha e le hantle, ts'ebetso ea lihlahisoa tse hlahisoang ke lihlahisoa tse fapaneng tse tala li tla fapana, 'me haeba matšoao a mang a tšoaneleha, litlhoko tsa boholo ba likaroloana le tsona li ka fokotsoa.

Boholo ba likaroloana bo angoa haholo ke ho roala ha ore e tala le mocheso oa calcination.Bokhoni ba ho apara bo khethoa ke boleng ba ore e tala, e amang haholo boholo ba karoloana ea sethala sa thepa e tala, 'me mocheso oa calcination o ama boholo ba phofo ka mor'a sebōpi.Bakeng sa barbotage calcination kaolin, mahareng mocheso calcination (1000 ~ 1200 ℃), e nepahetseng calcination mocheso o khethiloe karolong ea amorphous e sa tsoa fetoloa silicon aluminium spinel phase, e hlahisang sebopeho sa katoloso ea porous, e hlahisang nts'etsopele ea pore, le boleng ba abrasion ea sehlahisoa se batla se le tlase.

3.Ho koahela matla

Matla a koahelang ke index ea bohlokoa ka ho fetisisa ea calcined kaolin.Ha phofshoana e le e ntle haholoanyane, ho na le sebopeho se eketsehileng se entsoeng ka ho roala, ho matlafala ha refraction le ho bonahatsa leseli, haholo-holo ha boholo ba karoloana bo lekana le bolelele ba maqhubu a khanya e bonahalang, bo na le phello e matla ka ho fetisisa ea ho hasanya, e ka hlahisa matla a maholo ka ho fetisisa a koahelang, ha e le ka tlase ho boleng bona, matla a koahelang a tla fokotseha ka lebaka la ho fapanyetsana ha leseli.

Bakeng sa kaolin e ntle haholo, hore na e ka qhalakanngoa ka ho feletseng ka ho roala e boetse e le ntlha ea bohlokoa e amang matla a eona a ho koahela.Le hoja calcination e ntlafatsa matla a koahelang a kaolin ka holim'a metsi, ha ho bohlokoa.Maemong a mang, ho bonolo ho sintering le ho etsa likaroloana tse mahoashe, empa ho etsa hore matla a koahelang a fokotsehe, 'me a ke ke a sebelisoa bakeng sa ho roala ho hang.Bothata bo bong ke hore ka linako tse ling calcination e ka tlaase ho 1000℃ e hlahisa karolo e khubelu e khanyang, e mpe haholo. bakeng sa li-pigments tse tšoeu.1050℃ le phofo e ntle haholo.

4.Dispersiveness

Indasteri ea ho roala ka tlung e itse ho hasana, le mohopolo o ts'oana.Le hoja kaolin calcined e fetile ultrafine phofo, le ka karolelano phatsa boholo ba 1 μ m kapa ka tlaase ho moo, ka pente, ka viscosity phahameng motsoali joala, likaroloana ha ba arohane empa hlophisoa hammoho.Bokhoni ba kaolin ea calcined ea ho hasana ka har'a mokhoa oa ho roala bo bitsoa ho hasana.Ho hasana ha calcined kaolin ho molemo.Haeba sehlopha sa ho sila se finyella litlhoko tsa ho qetela, se ka qhalakanngoa ka har'a mokhoa oa ho roala.

Ho hasana ha kaolin ea calcined ho amana le phello ea ho qetela ea ho sila.Haeba 45 μ m kapa likaroloana tse kholoanyane li fumaneha ts'ebetsong e ntle haholo, e ke ke ea qhalakanngoa tsamaisong ea ho roala.Tlhokahalo ea index ena e ka tlase ho 45 μ m, 'me e nyane, e betere.Haeba ho hasana ha titanium dioxide ho ka fihla ho 25 μ m, ho lumellana le sehlopha sa ho sila ho lokela ho khethoa e le 4 kapa ho feta.

5.325 letlooeng sieve masalla

325 mesh sieve masalla ke index ea bohlokoa, tlhokahalo ea ho roala ho index ena ke <0.02%, 'me e nyenyane e molemo.325 mesh sieve e boetse e amana haholo le phello ea ho qetela ea ho sila, e hlokang 45 μ m kapa likaroloana tse khōloanyane nakong. ts'ebetso ea ultrafine.Ntho e 'ngoe e susumetsang ke litšila, tse kopantsoeng le litšila li na le phello e hlakileng ka ho fetisisa litabeng tsa tlhahlobo ea 325 mesh.

6.Boleng ba ho monya oli

Boleng ba ho monya oli ea calcined kaolin ke 50g / 100g ~ 60g / 100g e leka-lekane, palo ea ho monya oli e phahame haholo, viscosity ea ho roala e entsoeng ka foromo e ts'oanang e kholo, molemong oa ho fokotsa viscosity, palo ea motheo ea pente e tlameha ho etsoa. eketsa litšenyehelo;boleng ba ho monya oli bo tlase haholo, ho roala ho bonolo ho lokisoa, 'me ts'ebetso ea ho bula ha e ntle.Boleng ba ho monya oli ea kaolin ke kabo ea boholo ba likaroloana, porosity, sebaka se itseng sa bokaholimo, le mofuta oa lijo-thollo oa likaroloana.Boholo ba karoloana bo nyane, sebaka se ikhethileng se seholo, 'me boleng ba ho monya oli ke

7.Bophahamo ba ho rarolla

Boleng ba ho monya oli ea calcined kaolin ke 50g / 100g ~ 60g / 100g e leka-lekane, palo ea ho monya oli e phahame haholo, viscosity ea ho roala e entsoeng ka foromo e ts'oanang e kholo, molemong oa ho fokotsa viscosity, palo ea motheo ea pente e tlameha ho etsoa. eketsa litšenyehelo;boleng ba ho monya oli bo tlase haholo, ho roala ho bonolo ho lokisoa, 'me ts'ebetso ea ho bula ha e ntle.Boleng ba ho monya oli ea kaolin ke kabo ea boholo ba likaroloana, porosity, sebaka se itseng sa bokaholimo, le mofuta oa lijo-thollo oa likaroloana.Boholo ba karoloana bo nyane, sebaka se ikhethileng se seholo, 'me boleng ba ho monya oli bo phahame.

8.pH boleng

Boleng ba pH bo bontsha asiti le alkalinity ya kaolin e calcined, mme boleng ba pH bo lokela ho ba pakeng tsa 6 le 8, haholo-holo haufi le ho se nke lehlakore.PH ea kaolin e calcined ka boeona ha e nke lehlakore, kahoo phetoho ea PH ha e hlokehe indastering ea ho roala.

9.Ho hanyetsa boemo ba leholimo

Ka mor'a hore pigment e entsoe ka pente le daub, filimi ea pente ka letsatsi le pula, e tla fetoha mosehla, e lahleheloe ke leseli le phofo.Bokhoni ba mebala ea ho hanyetsa liphetoho tsena bo bitsoa ho hanyetsa boemo ba leholimo.Calcined kaolin ha e na ts'ebetso e matla ea lik'hemik'hale khanyeng, kahoo e na le khanyetso e ntle ea leholimo.

10.Lipontšo tse ling

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
