Q:How many eyes does the inner wall latex paint kaolin use?: Paint. (Emulsion), also known as synthetic resin emulsion coating, is a kind of organic coatings, is based on synthetic resin emulsion as base material, adding pigments, fillers and various additives made up of a kind of water-based paint. According to the production of different raw materials are mainly polyvinyl acetate latex paint latex paint, acrylic latex paint, pure acrylic and styrene acrylic latex paint and other varieties. According to the product applicable environment is different, divided into interior wall emulsion paint and exterior wall latex paint two kinds. According to gloss decoration can be divided into light, matte, semi light, mercerizing and other types of light. Latex paint has many advantages different from traditional wall paint, such as easy to brush, dry and so on. The methods of identifying latex paints are looking, smelling, wiping, brushing, pulling, and testing.

Q:What's the difference between Ye Lashi and kaolin?: The content of Si in Ye Lashi is much higher than that of Al. The amount of burning loss is relatively small, and the linear shrinkage is much smaller than that of kaolin. When adding to the raw material, the sintering process can promote sintering.

Q:I have kaolin, which is grey. It burns red. Do you need it?: And mainly hematite. I suggest you increase the whiteness after extracting hematite. After sintering is red kaolin, as ceramic soil, not many people, and the price can not go up, unless someone for the special use of the soil, as the base material is difficult to sell.

Q:The cosmetic effect of kaolin?: Kaolin is a nonmetal mineral, good quality products for whiteness high component, high temperature resistant, soft texture, good acid and alkali resistance, no stimulation to the skin, and has certain adsorption ability, remove skin dirt, grease on the skin absorption and waste etc..

Q:What is kaolin clay?: Ordinary clays, also called Gan Zi soil or kaolin, are mainly composed of kaolin mineralsBentonite, also called acid clay, is mainly composed of montmorillonite minerals

Q:How to identify kaolin?: Washed out kaolin can produce many unexpected consequences when used in the deployment of other raw materials.

Q:What are the surface modification technologies of calcined kaolin and the matters needing attention?: During the surface modification of calcined kaolin, it is necessary to react at a certain temperature. So, first of all to the calcined kaolin dynamic heating to a certain temperature (100 DEG C), in the high dynamic condition, adding after hydrolysis of silane coupling agent or compound modifier, adding to the best atomization. During the reaction between the coupling agent and kaolin, the temperature should be kept within 120 degrees, and at high speed, the time should be about 3-5 minutes.In addition, surface modification of kaolin and the reaction process, often produce false knot particles, the impact on the quality of the products is given, so the need for effective classification, only in this way can we fully guarantee the quality of products.

Q:Should kaolin be used in polyester production?: Some studies show that under certain conditions, adding kaolin inorganic particles of polyester fiber still has good spinnability and hygroscopicity, dyeability are improved, and has certain anti UV properties. However, the mechanical properties of modified polyester fiber declined due to the decrease of crystallinity.

Q:What is the good or bad of kaolin to distinguish? What is its criterion?What percentage does it contain and what element does it contain?: Whiteness is one of the main parameters of kaolin's technological properties. Kaolin with high purity is white. Kaolin whiteness, natural whiteness, and whiteness after calcination.The color of kaolin is mainly related to its metal oxides or organic matter. Containing Fe2O3 was rose red, brown and yellow; containing Fe2+ was pale blue, pale green with pale brown; MnO2; organic matter tends to yellow, gray, green, black and other colors. The presence of these impurities, reduced the natural whiteness of kaolin, in which iron and titanium minerals will also affect the whiteness of the calcined, porcelain stains or scars appear.

Q:The building is kaolin. Does it have radiation? District 15 years ago is a kaolin processing plant, there will be residual radiation it?: The first thing to stress is that the world is full of radiation, whether it's land, sea, mountains, fields, rocks, soil...... We call it the background radiation intensity".
