Kushandiswa kwemaindasitiri

Kaolin yava inodiwa chicherwa mbishi zvinhu zvakawanda maindasitiri akadai bepa kugadzira, Ceramics, rabha, makemikari, coatings, mushonga uye nyika kudzivirira.

Ceramic industry ndiyo yekutanga kushandiswa kwekaolin, yakawanda yeindasitiri. Iyo yakawanda dosage ndeye 20% ~ 30% yeformula. Basa re kaolin mumakeramics nderokuunza A1203, iyo inobatsira kuchizvarwa chemullite, kuvandudza kugadzikana kwekemikari uye simba rekunyunguduka, uye kuora kaolin kuita mullite mukupisa, kuumba chimiro chikuru chesimba rebhillet, iro inogona kudzivirira deformation yechigadzirwa, ita kuti kupisa kwekushisa kuwedzere, uye zvakare kuita kuti billet ive nehumwe huchena. Panguva imwecheteyo, kaolin ine imwe plasticity, adhesion, kumiswa uye kubatanidza kukwanisa, kupa porcelain dhaka, porcelain glaze yakanaka formability, kuitira kuti dope redongo rinobatsira kutendeuka uye grouting, nyore kuumba. Kana yakashandiswa muwaya, inogona kuwedzera kuvharidzira uye kuderedza dielectric kurasikirwa.

Ceramics haingove nezvinodiwa zvakasimba zvepurasitiki, kusunga, kuomesa shrinkage, kuomesa simba, sintering shrinkage, sintering properties, refractoriness uye post-firing whiteness ye kaolin, asiwo zvinosanganisira zvinhu zvemakemikari, kunyanya kuvapo kwesimbi, titanium, mhangura, chromium. , manganese nezvimwe zvinhu zvemavara, izvo zvinoderedza kuchena mushure mekupfura uye kuburitsa mavara.

Izvo zvinodikanwa zvegranularity zvekaolin zvinowanzoita zvakanaka, zviri nani, kuitira kuti dope revhu rive nepurasitiki yakanaka uye kuomesa simba, asi kune yekukanda iyo inoda kukurumidza kukanda, ichimhanyisa kumhanya kwekukanda uye kupera simba kwemvura, zvinodikanwa kuwedzera saizi ye. the ingredients. Mukuwedzera, mutsauko muchiyero chekristalllization ye kaolinite mu kaolinite ichaitawo zvakanyanya kushanda kwemaitiro e porcelain billet. Kana iyo dhigirii yekristallisation yakanaka, iyo plastiki uye kugona kusungirira yakaderera, iyo kuomeswa shrinkage yakaderedzwa, tembiricha yekupisa yakakwira, uye kusvibiswa kwemukati kunoderedzwawo. Pane zvinopesana, mapurasitiki ayo akakwirira, kuomeswa shrinkage yakakura, sintering tembiricha yakaderera, uye inoenderana netsvina yemukati zvakare yakakwirira.

Physicochemical pfuma

Zvivakwa: zvakasvibira zvakanyanya, zvakachena kana zvichena uye zvakapfava, senge zvine tsvina zvinogona kuve negrey, yero, brown uye mamwe mavara. Zvichienderana nekwakabva, chitarisiko chinogona kunge chakasununguka chivharo chevhu uye dense rock block.

Density: 2.54-2.60g / cm3. Nzvimbo yakanyungudika: inenge 1785 ℃.

Nepurasitiki, ivhu rakanyorova rinogona kuumbwa kuita akasiyana maumbirwo pasina kutyora, uye rinogona kuramba risingachinjiki kwenguva yakareba.
