Guilin Hongkaolin chigayo chakamira

Vagadziri vemidziyo yekukuya yeGuilin HongchengNdakadzidza kuti zvigadzirwa zvekukuya zvekaolin zvine calcium zvinonyanya kushandiswa muindasitiri yekuputira, iyo inoshandiswa sekuzadza pendi, kune rumwe rutivi inoita basa rekuzadza kwemuviri, kune rumwe rutivi ine simba rakati rekuvhara rakaoma. Saka, ndezvipi zvinodiwa zvezvigadzirwa zvekukuya zvekaolin zvine calcium?

Ma indekisi ezvigadzirwa zve kaolin yakakangwa yekupenda anosanganisira kuchena, saizi yezvikamu, simba rekufukidza, kupararira, masara e 325 mesh sieve, kukosha kwekunyudzwa kwemafuta, vhoriyamu yekuisa, pH kukosha, kuramba kwemamiriro ekunze nezvimwewo:

1. Dhigirii jena

Kuchena ndiko chiratidzo chikuru chekaolin yakakangwa, kana yakakwira zviri nani. Pendi yeruvara inogadzirwawo nependi chena sependi yekutanga uye amai veruvara. Kuchena kunofanira kunge kuri pamusoro pe90%, vamwe vagadziri vanotoda kupfuura 93%. Kugadzikana kwedhigirii jena kwakakosha zvikuru, kana kuchinja-chinja kwakanyanya kukanganisa mashandiro ekuona kwependi, zvichikonzera musiyano wemavara ezvigadzirwa zvakasiyana pasi pefomura imwe chete.

2. Kuwanda kwezvikamu

Saizi yezvikamu inyaya yekuratidza, vagadziri vemachira havawanzo kuona saizi yezvikamu. Zvisinei, nekuti zvimwe zviratidzo zvekaolin ine calcium zvine chekuita nehukuru hwezvikamu, kana saizi yezvikamu isina kukwana, kana isina kukodzera, icharatidzwa kuburikidza nezvimwe zviratidzo. Kune mugadziri wekaolin ine calcium, indekisi yekuongorora yechigadzirwa chakapedzwa inofanira kunge iri -2 μ m painenge 80%. Ehe, mashandiro ezvigadzirwa zvinogadzirwa nezvinhu zvakasiyana achasiyana, uye kana zvimwe zviratidzo zvikanyatsokodzera, zvinodiwa zvehukuru hwezvikamu zvinogonawo kuderedzwa.

Saizi yezvikamu inonyanya kukanganiswa nekusakara kwesimbi isina kugadzirwa uye tembiricha ye calcination. Kugona kusakara kunoenderana nemhando yesimbi isina kugadzirwa, iyo inonyanya kukanganisa saizi yesimbi yechikamu chechinhu chisina kugadzirwa, uye tembiricha ye calcination inonyanya kukanganisa saizi yesimbi mushure mekupiswa muchoto. Pakuputira calcination kaolin, calcination yepakati nepakati (1000~1200℃), tembiricha yepamusoro ye calcination inosarudzwa muchikamu chisina kugadzirwa chakangoshandurwa kuita silicon aluminum spinel phase, iyo inogadzira chimiro chekuwedzera kweporous, zvichikonzera kukura kwepore, uye kukosha kwekukwesha kwechigadzirwa kwakaderera.

3. Simba rekufukidza

Simba rekufukidza ndiro chiratidzo chakakosha chekaolin yakakora. Kana upfu hwakatsetseka, ndipo pahunowanikwa chimiro chakawanda mujira, ndipo panowedzera simba re refraction ne reflection yechiedza, kunyanya kana saizi ye particle yakaenzana ne wavelength yechiedza chinoonekwa, iine simba guru rekupararira, inogona kuburitsa simba guru rekufukidza, kana iri pasi peiyi kukosha, simba rekufukidza rinova diki nekuda kwekupararira kwechiedza.

Kana kaolin yakapfava zvakanyanya, kana inogona kupararira zvizere mupendi chinhu chakakosha chinokanganisa simba rayo rekufukidza. Kunyangwe calcination ichivandudza simba rekufukidza rekaolin mupendi yakagadzirwa nemvura, hazvina kukosha. Mune zvimwe zviitiko, zviri nyore kusviba uye kugadzira zvidimbu zvakakora, asi zvinoita kuti simba rekufukidza riderere, uye harigone kushandiswa pakuputira zvachose. Rimwe dambudziko nderekuti calcination iri pasi pe1000℃ dzimwe nguva inogadzira chikamu chitsvuku chakareruka, izvo zvakaipa kwazvo kune pigments chena.1050℃ uye superfine powder.

4. Kupararira

Indasitiri yekupenda yemumba yakati kupararira, uye pfungwa yacho yakafanana. Kunyangwe kaolin ine calcium yakapfurwa nehupfu hwakatsetseka, ine saizi yepakati pe 1 μ m kana pasi, mupendi, mune doro remubereki rine viscosity yakakura, zvidimbu hazvina kuparadzaniswa asi zvakaunganidzwa pamwe chete. Kugona kwekaolin ine calcium kupararira mu coating system kunonzi dispersion. Kupararira kwekaolin ine calcium kwakanaka. Kana grinding grade ichizadzisa zvinodiwa zvekupedzisira, inogona kupararira mukati me coating system.

Kupararira kwekaolin ine calcium kwakabatana nemigumisiro yekupedzisira yekukuya. Kana 45 μ m kana zvidimbu zvakakura zviri mukati mekugadzirisa kwakanaka kwazvo, hazvizoparadzirwe mu coating system. Chinodiwa che index iyi chiri pasi pe45 μ m, uye kana chidiki, zviri nani. Kana kupararira kwe titanium dioxide kuchigona kusvika 25 μ m, zvinoenderana ne grinding grade kunofanirwa kusarudzwa se4 kana kupfuura.

5.325 mesh sefa yakasara

325 mesh sieve residue inhamba yakakosha, chinodiwa chekufukidza iyi index i<0.02%, uye kana diki zviri nani.325 mesh sieve inonyanya kuenderana nemhedzisiro yekupedzisira yekukuya, isingade 45 μ m kana zvidimbu zvakakura panguva yekugadzirisa ultrafine. Chimwe chinhu chinopesvedzera tsvina, yakasanganiswa netsvina ine simba guru pakuongorora zviri mukati me325 mesh.

6. Kukosha kwemafuta

Kukosha kwekunwa mafuta kwekaolin yakakora ndeye 50g / 100g ~ 60g / 100g kuri pakati nepakati, huwandu hwekunwa mafuta hwakanyanya, viscosity yekuputira yakagadzirwa nefomura imwechete yakakura, kuti kuderedze viscosity, huwandu hwependi hwaro hunofanira kuwedzera mutengo; kukosha kwekunwa mafuta kwakaderera zvakanyanya, coating yakagadzirwa iri nyore kugadzirisa, uye mashandiro ekuvhura haana kunaka. Kukosha kwekunwa mafuta kwekaolin ndiko kugoverwa kwehukuru hwezvikamu, porosity, nzvimbo chaiyo yepamusoro, uye rudzi rwezviyo zvezvikamu. Saizi yezvikamu idiki, nzvimbo chaiyo yepamusoro yakakura, uye kukosha kwekunwa mafuta kuri

7. Huwandu hwekugadzirisa

Kukosha kwekunwa mafuta kwekaolin yakakora ndeye 50g / 100g ~ 60g / 100g kuri pakati nepakati, huwandu hwekunwa mafuta hwakanyanya, viscosity yekuputira yakagadzirwa nefomura imwechete yakakura, kuti kuderedze viscosity, huwandu hwependi hwaro hunofanira kuwedzera mutengo; kukosha kwekunwa mafuta kwakaderera zvakanyanya, coating yakagadzirwa iri nyore kugadzirisa, uye mashandiro ekuvhura haana kunaka. Kukosha kwekunwa mafuta kwekaolin ndiko kugoverwa kwehukuru hwezvikamu, porosity, nzvimbo chaiyo yekumusoro, uye rudzi rwezviyo zvezvikamu. Saizi yezvikamu idiki, nzvimbo chaiyo yekumusoro yakakura, uye kukosha kwekunwa mafuta kwakakwira.

Kukosha kwe8.pH

pH inoratidza acid nealkalinity ye calcined kaolin, uye pH inofanira kunge iri pakati pe6 ne8, inenge iri pedyo ne neutral. PH ye calcined kaolin pachayo haina neutral, saka PH modification haidiwi muindasitiri ye coating.

9. Kudzivirira mamiriro ekunze

Kana ruvara rwagadzirwa nependi uye rwaiswa dhayi, firimu rependi rinobuda muzuva nemvura rinoshanduka kuita yero, rorasikirwa nechiedza uye hupfu. Kugona kwemavara kurwisa shanduko idzi kunonzi kusashanda kwemamiriro ekunze. Kaolin ine calcium haina makemikari akasimba pachiedza, saka inodzivirirwa zvakanaka mumamiriro ekunze.

10. Zvimwe zviratidzo

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
