    Abstract : Titanium dioxide (TiO2) is a material with many useful properties. It is used most widely as a pigment in white paint, although in technological research it is better known for its ability to catalyze chemical reactions during light absorption. READ MORE

  4. 2. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

    Author : Mikael Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

    Abstract : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. READ MORE

  5. 3. Inhibition of light-induced colour reversion of wood-containing papers by means of coating

    Author : Helena Fjellström; Hans Höglund; Magnus Paulsson; Arthur Ragauskas; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-yield pulp; CTMP; birch; light-induced; ageing; photo-stabilising; lignin; coating; pigment; kaolin; calcium carbonate; titanium dioxide; binder; FWA; Chemical engineering; Kemiteknik;

    Abstract : The main purpose of this thesis was to find ways to maintain a low level of light‐induceddiscolouration at an increased addition of mechanical and chemimechanical pulps in coated highqualityfine paper and magazine paper grades. Current technology allows the production of highyieldpulps such as thermomechanical and chemimechanical pulps with properties suitable formanufacturing high‐quality paper or paperboard with a low basis weight.

  6. 4. Recovery and reuse of TiO2 and other pigments from paint waste

    Author : Mikael Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Titanium dioxide; Paint Waste; Recovery; Pyrolysis;

    Abstract : Titanium dioxide (TiO2) has numerous applications in our society, most notably as a white pigment in products such as paint, paper and plastic. Since 2010 there has been a sharp increase in the demand for and price of TiO2. As a result new and innovative ways of TiO2 production are needed. READ MORE
