Calcined kaolin

I-kaolin ene-calcined yavela e-United States, ekuqaleni ukususa ixabiso le-organic carbon kwi-kaolin ethambileyo kunye nokuphucula ubumhlophe bemveliso.Kamva, abantu basebenzisa le ndlela yokulungisa i-kaolin yomlinganiselo wamalahle, baza bavelisa iimveliso ezinentsebenzo, ezikumgangatho ophezulu, kunye nexabiso eliphezulu kakhulu kunekaolin eqhelekileyo.Yandisa kakhulu uluhlu lwesicelo se-kaolin.Ilizwe lam linobutyebi be-kaolin obuninzi bomlinganiselo wamalahle, kwaye ukubalwa yinkqubo engundoqo yomlinganiselo wamalahle womhlaba ophezulu.

Eyona njongo iphambili yokubala i-kaolin kuku:
1. Susa i-organic carbon kunye nezinye iiminerali ezingcolileyo ukuphucula ubumhlophe.
2. Susa amanzi kunye namaqela e-hydroxyl e-Kaolin ukunyusa umthamo we-void kunye ne-chemical reactivity yemveliso ye-calcined, ukuphucula iimpawu zomzimba kunye neekhemikhali, kunye nokuhlangabezana neemfuno ezahlukeneyo zesicelo.I-kaolin ene-calcined isuswa kwisakhiwo okanye amanzi e-crystal, i-carbon kunye nezinye izinto eziguquguqukayo, kwaye ibe yi-kaolinite, igama lokurhweba "i-calcined kaolin".
I-kaolin ene-calcined ineengenelo zobumhlophe obuphezulu, ukuxinana kwesambuku esincinci, indawo enkulu yendawo ethile kunye nomthamo wepore, ukufunxwa kakuhle kwe-oyile, ukugqunywa kunye nokuxhathisa i-abrasion, kunye nokugquma okuphezulu, ukumelana nemozulu kunye nokuzinza.

Iimbonakalo:
1. Ukwakhiwa kweekhemikhali kuzinzile, umlinganiselo we-molar we-Si02 / Al203 ngu-2/1.
2. Ubumhlophe bucocekile kwaye buzinzile, ubukhulu be-particle ubukhulu be-ultra-fine, kwaye ububanzi bokusabalalisa kunye ne-sieve ye-sieve iphantsi.
3. Ubume bekristale obunqabileyo buphelile, ukusabalalisa kukuhle, amandla okugubungela anamandla, kwaye ukujikeleza kuhle, kwaye akulula ukukhupha.

Ukusetyenziswa kweCalcined Kaolin
1. I-kaolin ene-calcined yokwaleka
Ubungakanani besicelo: Iindidi ezahlukeneyo zokugquma, kubandakanywa iipeyinti zelatex, iipeyinti zomgubo, iingubo ze-oyile kunye nezinye iindawo.
Iimpawu zeMveliso: ubumhlophe obuphezulu, ubungakanani bamasuntswana alungileyo, ukunganyaniseki kweekhemikhali, ukukwazi ukugquma okuphezulu, i-fluidity efanelekileyo kunye ne-floatability, ixabiso eliphantsi, njl., ezinokunciphisa imfuno yeedayi ezibizayo;Ukongeza kwezi mpawu ziqhelekileyo zingasentla, ikwanazo iingenelo zokumila ngendlela engaqhelekanga, iipropathi ezibalaseleyo zamehlo, izinga eliphezulu lokufunxa ioyile kunye noxinaniso lwepigment yepigment, akukho lula ukuguga, ukumelana nokunxiba kwaye kulula ukuyifaka emanzini okanye kwi-oyile medium, kwaye unamandla aphezulu okufihla.Eyona nto ibalulekileyo kukuba ingathatha indawo ye-titanium dioxide ebiza kakhulu, kwaye inokunciphisa i-photocoagulation phenomenon ebangelwa ukusetyenziswa kwe-titanium dioxide xa ixutywe kwaye isetyenziswe;ngakumbi ukuveliswa kwemibala efana ne-latex, inokwenza ukuba i-coating ibe ne-opacity engcono kunye ne-corrosion resistance.Ukuphucula ubulukhuni kunye nomgangatho wefilimu yokugubungela.

2. I-kaolin ene-calcined yerabha
Ububanzi besicelo: zonke iintlobo zeemveliso zerabha kunye neemveliso zeplastiki kunye ne-cable sheath, i-cable insulation layer kunye ne-PVC, i-PE kunye nezinye izinto zentambo.
Iimpawu zeMveliso: ukusabalalisa ubungakanani bamasuntswana afanelekileyo, ukuthungwa okucocekileyo, umxholo wokungahlambuluki ophantsi, umxholo we-kaolin ezilishumi omkhulu kune-98%, i-dispersibility enhle, ubungakanani bamasuntswana amahle, ubudlelwane obuhle kunye nerabha kunye neplastiki, iphuculwe kakhulu ekuqhutyweni kwerabha kunye neplastiki.Ine-inertness emihle yeekhemikhali kwaye ayifuni kunye neziyobisi okanye ezinye ii-reagents zekhemikhali kwiqondo lokushisa, ngaloo ndlela iphucula ukuxhathisa kwe-corrosion yeemveliso zentambo;i-refractoriness ephezulu inokuphucula ukushisa kwe-thermal denaturation yeemveliso zentambo;Iimpawu ezigqwesileyo zokufakelwa kombane, njl.

3. I-kaolin ene-calcined yeeseramikhi
Umda wosetyenziso: iiseramikhi zombane zamandla aphezulu naphantsi, iiseramikhi zombane ezisetyenziswa mihla le, iiseramikhi zococeko zokwakha, iikhemikhali ezikwaziyo ukutyiwa nokukhenkceza kubugcisa nemisebenzi yezandla.
Iimpawu zeMveliso: ubumhlophe obuphezulu, ukucoceka kweekhemikhali eziphezulu, ukuchasana okuphezulu, ukuchithwa kakuhle kunye nokuguquguquka, kunye nokuqikelelwa okuphezulu Ukubunjwa kunokutshintshwa ngokungekho mthethweni ngaphandle kokuqhekeka, kwaye imilo inokugcinwa ilungile emva kokususa amandla angaphandle, kwaye inokwakheka okulungileyo, ukomisa kunye neempawu ze-sintering.Iimveliso ezigxothiweyo zineempawu zombala omhlophe, ukudibanisa, amandla aphezulu omatshini kunye nesivuno esiphezulu.
