I-calcined kaolin

I-kaolin egayiwe yavela e-United States, ekuqaleni ukuze isuse inani le-organic carbon ku-kaolin ethambile futhi ithuthukise ubumhlophe bomkhiqizo.Kamuva, abantu basebenzisa le ndlela ukucubungula i-kaolin yesilinganiso samalahle, futhi bakhiqiza imikhiqizo esebenza kahle, esezingeni eliphezulu, futhi enenani eliphakeme kakhulu kune-kaolin evamile.Yandisa kakhulu ububanzi bokusetshenziswa kwe-kaolin.Izwe lami linezinsiza eziningi ze-kaolin yesilinganiso samalahle, futhi ukubala kuyinqubo ebalulekile ebalulekile yenhlabathi enesilinganiso samalahle esiphezulu.

Inhloso eyinhloko ye-kaolin calcination iwukuba:
1. Khipha i-organic carbon kanye namanye amaminerali angcolile ukuze uthuthukise ubumhlophe.
2. Susa amanzi kanye namaqembu e-hydroxyl e-Kaolin ukuze ukhuphule umthamo ongenalutho kanye nokusebenza kabusha kwamakhemikhali omkhiqizo owenziwe nge-calcined, uthuthukise izici zomzimba namakhemikhali, futhi uhlangabezane nezidingo ezihlukahlukene zohlelo lokusebenza.I-kaolin ebaliwe ikhishwa esakhiweni noma emanzini ayikristalu, ikhabhoni nezinye izinto eziguquguqukayo, bese iba yi-kaolinite, igama lokuhweba elithi “calcined kaolin”.
I-kaolin ebaliwe inezinzuzo zokuba mhlophe okuphezulu, ukuminyana kwenqwaba encane, indawo enkulu ethize engaphezulu kanye nevolumu yembotshana, ukumuncwa kahle kukawoyela, ukumboza kanye nokumelana nokuhuzuka, nokufakwa okuphezulu, ukumelana nesimo sezulu nokuzinza.

Izici:
1. Ukwakheka kwamakhemikhali kuzinzile, isilinganiso se-molar sika-Si02/Al203 singu-2/1.
2. Ubumhlophe bumsulwa futhi buzinzile, usayizi wezinhlayiyana u-ultra-fine, futhi ububanzi bokusabalalisa kanye nezinsalela zesisefo ziphansi.
3. Umumo wekristalu ongenalutho uphelele, ukuhlakazeka kuhle, amandla okuvala aqinile, futhi ukuntanta kuhle, futhi akulula ukusho.

Ukusetshenziswa kwe-Kaolin Calcined
1. I-kaolin ene-calcined yokugcoba
Ububanzi bokusebenza: Izinhlobo ezahlukahlukene zokumboza, kufaka phakathi amapende e-latex, ama-powder coatings, ama-coatings asuselwa kuwoyela neminye imikhakha.
Izici zomkhiqizo: ubumhlophe obuphezulu, ubungako bezinhlayiya ezinhle, ukungabi namakhemikhali kwamakhemikhali, ikhono eliphezulu lokumboza, uketshezi olufanele kanye nokuntanta, izindleko eziphansi, njll., okunganciphisa isidingo samadayi abizayo;ngaphezu kwezici ezivamile ezingenhla, iphinde ibe nezinzuzo zokuma okungajwayelekile, izakhiwo ezinhle kakhulu ze-optical, izinga eliphezulu lokumuncwa kwamafutha kanye nokugxila kwevolumu ye-pigment, akulula ukuguga, ukumelana nokugqoka futhi kulula ukuyifaka emanzini noma ku-oyela medium, futhi inamandla okucasha aphezulu.Okubaluleke kakhulu ukuthi ingathatha indawo ye-titanium dioxide ebizayo, futhi inganciphisa ukwenzeka kwe-photocoagulation okubangelwa ukusetshenziswa kwe-titanium dioxide lapho ixutshwe futhi isetshenziswa;ikakhulukazi ukukhiqizwa kwezingulube ezifana ne-latex, kungenza ukugqoka kube ne-opacity engcono nokumelana nokugqwala.Thuthukisa ubulukhuni kanye nekhwalithi yefilimu yokugqoka.

2. I-kaolin ene-calcined yerabha
Ububanzi bokufaka isicelo: zonke izinhlobo zemikhiqizo yenjoloba nemikhiqizo yepulasitiki nesigxobo sekhebula, isendlalelo sokufakwa kwekhebula kanye ne-PVC, i-PE nezinye izinto zekhebula.
Izici zomkhiqizo: ukusabalalisa usayizi wezinhlayiyana ezifanele, ukuthungwa okumsulwa, okuqukethwe okungcolile okuphansi, okuqukethwe kwe-kaolin okuyishumi okukhulu kuno-98%, ukuhlakazeka okuhle, usayizi wezinhlayiyana ezinhle, ukuhlobana okuhle nenjoloba nepulasitiki, kuthuthukiswe kakhulu ekucubunguleni iraba nepulasitiki.Inokungena kahle kwamakhemikhali futhi ayiphenduli ngezidakamizwa noma amanye ama-reagents amakhemikhali ekamelweni lokushisa, ngaleyo ndlela ithuthukise ukumelana nokugqwala kwemikhiqizo yekhebula;refractoriness high kungathuthukisa izinga lokushisa denaturation ezishisayo imikhiqizo ikhebula;Izakhiwo ezinhle kakhulu zokuvala ugesi, njll.

3. I-kaolin ene-calcined yezitsha zobumba
Ububanzi bokusebenza: izitsha zobumba zikagesi ezinamandla aphezulu naphansi, izitsha zobumba ezisetshenziswa nsuku zonke, izitsha zobumba zesakhiwo sanitary, izitsha zobumba ezimelana nokugqwala kwamakhemikhali kanye nezicwebezelisiwe zobuciko nemisebenzi yezandla.
Izici zomkhiqizo: ubumhlophe obuphezulu, ukuhlanzeka kwamakhemikhali okuphezulu, ukuphikiswa okuphezulu, ukuhlakazeka okuhle kanye noketshezi, kanye nokubikezela okuphezulu Umumo ungashintshwa ngaphandle kokuqhekeka, futhi umumo usengagcinwa uqinile ngemuva kokukhipha amandla angaphandle, futhi unokwakheka okuhle, okomisa kanye nezindawo zokushisa.Imikhiqizo exoshiwe inezici zombala omhlophe, ukubumbana, amandla aphezulu emishini kanye nesivuno esikhulu.
