It is mainly used in papermaking ceramics and refractory materials followed by coatings rubber fillers enamel glazes and white cement raw materials and a small amount is used in plastics paints pigments grinding wheels pencils Daily cosmetics soap pesticides medicine textiles petroleum chemicals building materials national defense and other
Chat Online· Japan is outstandingly important in use of high value kaolins and an estimated 85 of imports used in the papermaking industry. Fibreglass manufacturing in Taiwan has been also a very important consumer of imported kaolin and it is only now that this is being stemmed mainly by re-location of several major fibreglass producers to China.
Chat OnlineKaolin was formerly the most widely used mineral filler and coating pigment in paper manufacture but in the last two decades has been steadily supplanted by calcium carbonate. The two causes for this have been the conversion from acid to alkaline papermaking and demand for brighter and bulkier paper.
Chat OnlineIn this study cesium was added intentionally during paper manufacture for protecting the papers against forgery and counterfeiting by sorbing cesium ions (Cs ) on kaolin used as special filler in papermaking. The sorption of cesium from aqueous solution by kaolin was studied as a function of pH shaking time cesium initial concentration and mass of kaolin using batch technique.
