Ukusasazwa kobungakanani bamasuntswana
Ukusasazwa kobungakanani bamasuntswana kubhekisa kumlinganiselo (obonakaliswa ngokwepesenti yomxholo) wamasuntswana kwi-kaolin yendalo ngaphakathi koluhlu oluthile lobukhulu obuhlukeneyo obuqhubekayo (obonakaliswa ngobukhulu be-mesh yeemilimitha okanye ii-micrometer). Iimpawu zokusasazwa kobungakanani bamasuntswana e-kaolin zibaluleke kakhulu ekukhetheni nasekusetyenzisweni kwenkqubo yee-ores. Ubungakanani bamasuntswana ayo bunempembelelo enkulu kwi-plasticity yayo, i-viscosity yodaka, amandla okutshintshiselana kwee-ion, ukusebenza kokubumba, ukusebenza kokomisa, kunye nokusebenza kokusila. I-ore ye-kaolin ifuna ukucutshungulwa kobuchwephesha, kwaye nokuba kulula ukuyicubungula ukuya kubunzulu obufunekayo ibe ngomnye wemigangatho yokuvavanya umgangatho we-ore. Isebe ngalinye lemizi-mveliso lineemfuno ezithile zobukhulu bamasuntswana kunye nobukhulu bokusetyenziswa okuhlukeneyo kwe-kaolin. Ukuba i-United States ifuna ukuba i-kaolin isetyenziswe njengengubo ibe ngaphantsi kwe-2 μ Umxholo we-m ubandakanya i-90-95%, kwaye isizali sephepha singaphantsi kwe-2 μ Umlinganiselo we-m yi-78-80%.

Ukuqina kweplastiki
Udongwe olwenziwe ngokudityaniswa kwe-kaolin namanzi lunokonakala phantsi kwamandla angaphandle, kwaye emva kokuba amandla angaphandle esusiwe, lusenokugcina olu phawu lokuguquguquka, olubizwa ngokuba yi-plasticity. I-plasticity sisiseko senkqubo yokwenza i-kaolin kwimizimba ye-ceramic, kwaye ikwaluphawu oluphambili lobuchwephesha lwenkqubo. Ngokwesiqhelo, i-plasticity index kunye ne-plasticity index zisetyenziselwa ukumela ubungakanani be-plasticity. I-plasticity index ibhekisa kumxholo womswakama womda wolwelo wezinto zodongwe ze-kaolin ngaphandle komxholo womswakama womda weplastiki, ochazwe njengepesenti, oko kukuthi i-W plasticity index=100 (W liquid limit – W plasticity limit). I-plasticity index imele ukwakheka kwezinto zodongwe ze-kaolin. Umthwalo kunye nokuguquguquka kwebhola yodongwe ngexesha lokucinezelwa nokutyunyuzwa kunokulinganiswa ngokuthe ngqo kusetyenziswa i-plasticity meter, echazwe kwi-kg · cm. Rhoqo, xa i-plasticity index iphezulu, kokukhona i-plasticity index ingcono. I-plasticity ye-kaolin inokwahlulwa ibe ngamanqanaba amane.

Ubudlelwane

Ukubophelela kubhekisa kubuchule be-kaolin bokudibanisa nezinto ezingezizo zeplastiki ukwenza udongwe lweplastiki kwaye lube namandla athile okomisa. Ukumisela ubuchule bokubopha kubandakanya ukongeza isanti ye-quartz eqhelekileyo (enobunzima obuyi-0.25-0.15 particle size fraction ebalelwa kwi-70% kunye ne-0.15-0.09mm particle size fraction ebalelwa kwi-30%) kwi-kaolin. Umxholo ophezulu wesanti xa isenako ukugcina ibhola yodongwe lweplastiki kunye namandla okugoba emva kokomisa zisetyenziselwa ukumisela ukuphakama kwayo. Okukhona isanti ininzi yongezwa, kokukhona amandla okubopha alo mhlaba we-kaolin eqinileyo. Ngokwesiqhelo, i-kaolin ene-plasticity enamandla ikwanawo namandla okubopha aqinileyo.

Ukusebenza kokomisa
Ukusebenza kokomisa kubhekisa ekusebenzeni kodaka lwe-kaolin ngexesha lenkqubo yokomisa. Oku kuquka ukuncitshiswa kokomisa, amandla okomisa, kunye nobuthathaka bokomisa.

Ukuncipha kokomisa kubhekisa ekuncipheni kodongwe lwe-kaolin emva kokuphelelwa ngamanzi emzimbeni kunye nokomisa. Udongwe lwe-kaolin ludla ngokuphelelwa ngamanzi emzimbeni kunye nokomisa kumaqondo obushushu aqala kwi-40-60 ℃ ukuya kwi-110 ℃. Ngenxa yokukhutshwa kwamanzi, umgama wamasuntswana uyafinyezwa, kwaye ubude kunye nomthamo wesampuli ziyancitshiswa. Ukuncipha kokomisa kwahlulwe kukuncipha okuthe ngqo kunye nokuncitshiswa kwevolumu, okubonakaliswa njengepesenti yotshintsho kubude kunye nomthamo wodaka lwe-kaolin emva kokomisa ukuya kubunzima obungaguqukiyo. Ukuncipha kokomisa kwe-kaolin ngokubanzi yi-3-10%. Okukhona ubukhulu bamasuntswana bucotha, kokukhona indawo ethile yomphezulu inkulu, kokukhona iplastiki iba ngcono, kwaye kokukhona ukomisa kuncinci kakhulu. Ukuncipha kohlobo olufanayo lwe-kaolin kuyahluka ngokuxhomekeke kubungakanani bamanzi ongezelelweyo.

Iiseramikhi azinazo nje kuphela iimfuno ezingqongqo zeplastiki, ukunamathela, ukushwabana kokomisa, amandla okomisa, ukushwabana kokusila, iimpawu zokusila, ukumelana nomlilo, kunye nobumhlophe emva kokudubula kwekaolin, kodwa zikwabandakanya iimpawu zeekhemikhali, ingakumbi ubukho bezinto zechromogenic ezifana nentsimbi, i-titanium, i-copper, i-chromium, kunye ne-manganese, ezinciphisa ubumhlophe emva kokudubula kwaye zivelise amabala.
