I-Kaolin, iminerali engeyoyesinyithi, luhlobo lodongwe nodongwe oluqulunqwe ikakhulu ziiminerali zodongwe zeqela le-kaolinite. Ngenxa yembonakalo yayo emhlophe nethambileyo, ikwaziwa njengomhlaba weBaiyun. Izinto eziphambili yi-aluminium trioxide kunye ne-silicon dioxide.

I-kaolin yayo ecocekileyo imhlophe, ithambile, kwaye ithambile ngokwendlela ebukeka ngayo, ineempawu ezintle zomzimba nezekhemikhali ezifana ne-plasticity kunye nokumelana nomlilo. Ulwakhiwo lwayo lweeminerali luquka ikakhulu i-kaolinite, i-halloysite, i-hydromica, i-illite, i-montmorillonite, kunye neeminerali ezifana ne-quartz kunye ne-feldspar.

Iimpawu zenkqubo:

1. Ukukhanya Okumhlophe – Umhlophe yenye yezona parameter ziphambili zokusebenza kwe-kaolin, kwaye i-kaolin ecocekileyo kakhulu imhlophe. Umhlophe we-kaolin wahlulwe waba bumhlophe bendalo kunye nobumhlophe obune-calcium. Kwizinto eziluhlaza ze-ceramic, ubumhlophe emva kwe-calcination bubaluleke ngakumbi, kwaye okukhona ubumhlophe obune-calcium buphezulu, kokukhona umgangatho ungcono.

2. Ukusasazwa kobungakanani bamaqhekeza – Ukusasazwa kobungakanani bamaqhekeza kubhekisa kumlinganiselo (ochazwa ngokwepesenti yomxholo) wamaqhekeza kwi-kaolin yendalo ngaphakathi koluhlu oluthile lobukhulu obuhlukeneyo obuqhubekayo (obonakaliswa ngeemilimitha okanye nge-micrometer mesh). Icandelo ngalinye lemizi-mveliso lineemfuno ezithile zobukhulu bamaqhekeza kunye nokuqina kwe-kaolin ngeenjongo ezahlukeneyo. I-United States ifuna ukuba i-kaolin esetyenziswa njengengubo ibe nomxholo ongaphantsi kwe-2 μ m (6250 mesh), ebalelwa kwi-90-95%, kwaye izizalisi zokwenza iphepha ezinomxholo ongaphantsi kwe-2 μ m zimalunga ne-78-80%. Kwiinkqubo zokuphosa ezifuna ukuphosa ngokukhawuleza, isantya sokugrumba esikhawulezileyo, kunye nesantya sokuphelelwa ngamanzi emzimbeni, kuyimfuneko ukwandisa ubungakanani bamaqhekeza ezithako.

3. Ukumiswa: Ukumiswa kunye nokusasazwa kubhekisa kwiimpawu ze-kaolin ezinzima ukuzinqanda xa zisasazwa emanzini. Ekwaziwa nangokulwa nokungqubana. Okukhona ubukhulu bezinto ezincinci, kokukhona ukumiswa kungcono. I-Kaolin esetyenziswa kwishishini le-enamel ifuna iimpawu ezilungileyo zokumiswa. Ukusebenza kokumiswa kwesampuli esasazwa emanzini ngokuqhelekileyo kuxhomekeka kwisantya sayo sokumiswa kwixesha elithile.

4. Ukufakwa kombane: I-kaolin esemgangathweni ophezulu ineempawu ezilungileyo zokufakwa kombane, ezinokusetyenziselwa ukwenza iiseramikhi ezisebenzisa i-frequency ephezulu kunye neeseramikhi ezingenazingcingo. Inqanaba lokusebenza kokufakwa kombane linokulinganiswa ngokukwazi kwayo ukumelana nokonakala kombane.

Udidi:

I-kaolin ehlanjwe ngamanzi ehlanjwe nge-calcium ecoliweyo

Ukusetyenziswa:

I-Kaolin inoluhlu olubanzi lweendlela ezisetyenziswa ngazo, ikakhulu ekwenziweni kwephepha, kwiiseramikhi, nakwizinto ezirhabaxa, ilandelwa zizinto zokugquma, izizalisi zerabha, iiglaze ze-enamel, kunye nezinto eziluhlaza zesamente emhlophe. Ngomlinganiselo omncinci, isetyenziswa kumacandelo emizi-mveliso afana neeplastiki, iipeyinti, ii-pigment, amavili okugaya, iipensele, izinto zokuthambisa zemihla ngemihla, isepha, amalaphu, ipetroli, iikhemikhali, izixhobo zokwakha, njl.
