Ndezvipi zvinodiwa index ye calcined kaolin inoshandiswa kugadzira zvigadzirwa zvekunamira?

Guilin Hongkaolin vertical mill

Guilin Hongcheng vagadziri vemidziyo yekukuyaakadzidza kuti calcined kaolin grinding products anonyanya kushandiswa muindastiri yekuputira, iyo inoshandiswa sekuzadza mupende, kune rumwe rutivi inobata basa rekuzadza muviri, kune rumwe rutivi ine imwe yakaoma yekuvhara simba.Saka, ndezvipi zvinodikanwa zveindex ye calcined kaolin yekukuya zvigadzirwa?

Zvigadzirwa zve calcined kaolin zvekuputira zvinonyanya zvinosanganisira kuchena, particle size, simba rinovhara, kupararira, 325 mesh sieve zvakasara, mafuta absorption kukosha, deposition volume, pH kukosha, kuramba mamiriro ekunze uye zvichingodaro:

1.White degree

kuchena ndiyo yekutanga index ye calcined kaolin, iyo yakakwirira zviri nani.Iyo pendi yeruvara inogadzirwawo nependi chena sependi yepasi uye ruvara rwaamai.kuchena kunofanira kunge kuri kupfuura 90%, vamwe vanogadzira vanotoda kupfuura 93%.White dhigirii kugadzikana kwakakosha zvakanyanya, kana kuchinjika kwacho kwakakurisa kuti zvikanganise mashandiro eoptical yejasi, zvichikonzera mutsauko wemavara emabhechi akasiyana ezvigadzirwa pasi peforamu imwechete.

2.Granularity

Particle size indekisi yekumiririra, vanogadzira zvekupfeka kashoma kuti vaone saizi yechikamu.Zvisinei, nokuti zvimwe zviratidzo zve calcined kaolin zvine chokuita nekukura kwechidimbu, kana saizi yepakati haina kunaka zvakakwana, kana kuti isina kukodzera, icharatidzwa kuburikidza nezvimwe zviratidzo.Kune iyo calcined kaolin mugadziri, indekisi yekuongorora yechigadzirwa chakapedzwa inofanira kuva-2 μ m inenge 80%.Ehezve, kuita kwezvigadzirwa zvinogadzirwa neyakasiyana mbizha zvinhu zvichave zvakasiyana, uye kana zvimwe zviratidzo zvinokodzera, iyo particle size inodiwa inogonawo kuderedzwa.

Iyo particle size inonyanya kukanganiswa nekupfeka kwesimbi yakasvibira uye tembiricha yecalcination.Kugona kupfeka kunotarwa nemhando yeore yakasvibirira, iyo inonyanya kukanganisa saizi yechikamu cheyakagadzirwa, uye tembiricha yecalcination inonyanya kukanganisa saizi yehupfu mushure memoto.Nekuputira calcination kaolin, yepakati tembiricha calcination (1000 ~ 1200 ℃), iyo yakakwana calcination tembiricha inosarudzwa muchikamu cheamorphous changoshandurwa kuita silicon aluminium spinel phase, iyo inoburitsa porous yekuwedzera chimiro, zvichikonzera kukura kwepore, uye kukosha kweabrasion ye chigadzirwa chakaderera.

3.Kuvhara simba

Kuvhara simba ndiyo inonyanya kukosha index ye calcined kaolin.Iyo yakatsetseka yehupfu, iyo yakawanda inoumbwa mukuputira, iyo inosimba refraction uye kuratidza kwechiedza, kunyanya kana particle size yakaenzana newavelength yechiedza chinooneka, ine simba rakasimba rekuparadzira, rinogona kuburitsa simba guru rekuvhara, kana iri pasi pehukoshi uhu, simba rekuvhara rinova diki nekuda kwekusiyana kwechiedza.

Nokuda kwekaolin yakanyanyisa, kana inogona kuparadzirwa zvakakwana mukuputira zvakare chinhu chinokosha chinokanganisa simba rayo rekuvhara.Kunyange zvazvo calcination inovandudza simba rekuvhara re kaolin mumvura-based coating, haina kukosha.Mune zvimwe zviitiko, zviri nyore kuita sintering uye kugadzira zvidimbu zvakakoshwa, asi zvinoita kuti simba rekuvhara riderere, uye harigone kushandiswa pakuputira zvachose. zvewhite pigments.1050℃ uye superfine powder.

4.Disperssiveness

Indasitiri yekupfeka yepamba yakati kupararira, uye pfungwa yakafanana.Kunyangwe iyo calcined kaolin yakave neultrafine poda, ine avhareji yehukuru hwema 1 μ m kana zvishoma, mupende, mune yakakwirira viscosity mubereki doro, zvimedu hazvina kuparadzaniswa asi zvakabatanidzwa pamwechete.Kugona kwe calcined kaolin kupararira mu coating system kunonzi dispersion.Kupararira kwecalcined kaolin kwakanaka.Kana iyo giredhi yekukuya inosangana nezvinodiwa zvekupedzisira, inogona kuparadzirwa mukati meiyo coating system.

Kupararira kwecalcined kaolin kunoenderana nemhedzisiro yekukuya.Kana 45 μ m kana zvimedu zvakakura zviri mukati meiyo superfine processing process, haizoparadzirwe mune yekupfeka system.Chinodiwa cheiyi index chakaderera pane 45 μ m, uye iyo diki, iri nani.Kana kupararira kwetitanium dioxide kunogona kusvika 25 μ m, inoenderana negiredhi yekukuya inofanira kusarudzwa se4 kana kupfuura.

5.325 mesh sieve zvakasara

325 mesh sieve residu indekisi yakakosha, zvinodiwa zvekuputira kune iyi index ndeye <0.02%, uye zviduku zviri nani.325 mesh sieve inonyanya kuenderana nekuguma kwekupedzisira kwekukuya, inoda kwete 45 μ m kana zvidimbu zvakakura panguva. Ultrafine processing.Chimwe chinofurira chinhu kusachena, kusanganiswa netsvina kune zvakanyanya kukonzeresa pane yekuongorora ye325 mesh.

6.Oil absorption value

Iko kunyura kwemafuta kukosha kwe calcined kaolin ndeye 50g / 100g ~ 60g / 100g iri pakati nepakati, iyo mafuta yekunyura yakawandisa, iyo yekubikira viscosity yakagadzirwa neiyo fomula yakakura, kuti uderedze viscosity, huwandu hwependi base hunofanira. kuwedzera mari;kukosha kwekutora mafuta kwakadzikira, iyo yekupfeka yakagadzirwa iri nyore kugadzirisa, uye kuvhura kuita hakuna kunaka.Kunyura kwemafuta ukoshi hwekaolin is particle size distribution, porosity, chaiyo surface area, uye rudzi rwezviyo zvezvimedu.Saizi yechikamu idiki, iyo chaiyo nzvimbo yakakura, uye kukosha kwemafuta kunyura

7.Settlement volume

Iko kunyura kwemafuta kukosha kwe calcined kaolin ndeye 50g / 100g ~ 60g / 100g iri pakati nepakati, iyo mafuta yekunyura yakawandisa, iyo yekubikira viscosity yakagadzirwa neiyo fomula yakakura, kuti uderedze viscosity, huwandu hwependi base hunofanira. kuwedzera mari;kukosha kwekutora mafuta kwakadzikira, iyo yekupfeka yakagadzirwa iri nyore kugadzirisa, uye kuvhura kuita hakuna kunaka.Kunyura kwemafuta ukoshi hwekaolin is particle size distribution, porosity, chaiyo surface area, uye rudzi rwezviyo zvezvimedu.Saizi yechikamu idiki, iyo chaiyo nzvimbo yakakura, uye kukosha kwemafuta kunyura kwakakwira.

8.pH kukosha

Iyo pH kukosha inoratidza asidhi uye alkalinity ye calcined kaolin, uye kukosha kwepH kunofanirwa kunge kuri pakati pe6 ne8, zvakanyanya pedyo nekusarerekera.Iyo PH yekaolin yakarukwa pachayo haina kwayakarerekera, saka iyo PH shanduko haidiwi muindasitiri yekupfekedza.

9.Weather kuramba

Mushure mokunge iyo pigment yakagadzirwa nepende uye daub, firimu yepende kuburikidza nezuva nemvura, inoshanduka yero, kurasikirwa nechiedza uye upfu.Kugona kwe pigment kuramba shanduko idzi kunonzi kupikisa mamiriro ekunze.Calcined kaolin haina makemikari akasimba ekuita pachiedza, saka ine yakanaka yemamiriro 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
