    Core tips: the formulation and process of high temperature resistant zinc iron yellow pigment are mainly used in the field of chemical pigments, such as chimney coating, coil coating, plastic coating, asphalt coating, new building coating, environmental protection coating, etc

    Formula of high temperature resistant zinc iron yellow pigment (total 100kg): Market iron oxide yellow 70kg Zinc oxide 29kg Alumina 1kg The process is as follows: the mixture of 70kg of commercial iron oxide yellow, 29kg of zinc oxide and 1kg of alumina is mixed for 4h, calcined at 1100 ℃ for 15min, and then calcined at 10mi Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form

    It is a new type of coating, because of its own advantages and more and more known by people

    Let's introduce Akzo Nobel Powder coating

    Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products

    After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment

    Since the introduction of this technology, powder coating has been able to continue to maintain the Home of coatings: the formulation and process of high temperature resistant zinc iron yellow pigment, which is mainly used in the field of chemical pigments, is mainly used in chimney coating, coil coating, plastic coating, asphalt coating, new building coating, environmental protection coating, etc

    Formula of high temperature resistant zinc iron yellow pigment (100kg in total): 70kg of commercial iron oxide yellow, 29kg of zinc oxide, 1kg of aluminum oxide: mix the mixture of 70kg of commercial iron oxide yellow, 29kg of zinc oxide and 1kg of aluminum oxide for 4h, calcine it at 1100 ℃ for 15min, cool it to 450 ℃ for 10min, grind it to the particle size of 0.1 ~ 0.6 μ m, and then inspect, pack and store it

    The above products were mixed into PVA latex paint in the same proportion with other common products on the market, and analyzed by colorimeter: primary color wash light color (1:5) brightness 54.41 (51.67) 77.64 (77.16) red green part 25.51 (25.54) 13.93 (14.91) Yellow blue part 39.96 (38.93) 29.26 (28.25) miscellaneous part 47.41 (46.56) 32.41 (31.94) coloring power 101 (100) - from the color analysis data, it can be seen that the pigment is relatively bright, relatively yellow, high coloring power, 20000 times of electron microscope photos, the average width of pigment particles is 0.2 μ m, length is 0.6 μ m, oil absorption is 19g / 100g
