MODIFIED ALUMINUM SILICATE FOR NYLON(GB-CKP107)

Q: What are the surface modification technologies of calcined kaolin and the matters needing attention?: At present, the modified calcined kaolin is mainly applied to the organic products industry, with the industry of organic raw material, processing technology and technical performance requirements are different, so the surface modification of calcined kaolin to put forward an important problem that how to adapt and meet the requirements, and can display the function of modified kaolin.The modified kaolin can play a functional role, first of all technical aspects should pay attention to all kinds of organic polymer products raw materials and production process, is not able to complement each other, in the process of phase cancellation, careful analysis of raw material quality, specifications and design of process parameters and process conditions, these factors can affect the application effect of modified kaolin.In order to improve the surface modification of kaolin, it is necessary to understand the main technical requirements, main raw materials and processing technology of organic polymer products. Should be based on this, targeted to select good modifier, adjust the formula of modified agents, determine the reasonable processing technology.

Q: What's the difference between nano kaolin, washed kaolin and calcined kaolin? Where is the difference?: Nano kaolin means that the granularity of kaolin is reduced to nanometer scale, a nanometer equal to 1/1000 microns.

Q: What are the requirements for kaolin as refractory material, such as how much aluminum is needed?: Kaolin as refractory material actually plays two roles, one is to improve refractoriness, and two is to improve the body plasticity of refractory material

Q: Describe the formation of kaolin on kaolin Hill: Kaolin is a nonmetallic mineral, a kind of clay and clay rock mainly composed of kaolinite group clay minerals. Because of the white and delicate, also known as "white cloud soil.". [name] because of kaolin village, Jiangxi, Jingdezhen province.

Q: What is the difference between chemical pure and pure analysis of kaolin?: The analysis of pure (AR) is the purity specifications of chemical reagents, belong to grade two, analysis of pure tags for Jin Guanghong, for general test (prepared in the quantitative analysis of common solution); for the specific drug purity, different requirements are not the same.

Q: What is the solid content in kaolin index?: Refers to the content of kaolin will not be issued, the method of detection is not very clear.

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: Which mixer can be more evenly dispersed kaolin slurry?: If you love to drink fruit juice drinks of all kinds, so it is recommended to select with mixer speed regulation, so that you can freely adjust the stirring speed, some fruit juice does not need to stir too broken to drink. Therefore, you can choose a mixer with speed control function.

Q: What's the difference between kaolin and clay?: White pottery is made from kaolin. Now the international general kaolin scientific name --Kaolin, is the source of the eastern suburbs of Jingdezhen Gaoling village of Gaoling mountain.Kaolin plasticity, adhesion, certain drying strength, sintering and sintering whiteness and other special properties, make it become the main raw material of ceramic production; white, soft, high dispersion, adsorption and chemical process with excellent performance, which was widely used in papermaking industry. In addition, kaolin also is widely used in rubber, plastic, refractory material, petroleum refining industry, agriculture and national defense technology field. According to the purpose and need for processing, processing and purification, all of them can be used to produce activated clay.

Q: The difference between calcined clay and calcined kaolin: Calcination can also make the crystal structure of kaolin changes (mainly caused by hydrogen bonding and crystal water removal layer), from the original ordered lamellar crystal structure of kaolin into disordered metakaolin, the exposed parts of the original crystal layer group, and due to remove water of crystallization, type and quantity of surface active the increase (the type changed from -OH to Si-O, Al-O and part of the remaining -OH), the reaction activity increased.Calcined kaolin can lead to particle size increased, while the decrease of surface area, adsorption decreased, but the decrease of surface energy, to improve the dispersibility of kaolin, and the amorphous structure became loose, but also can improve the dispersion of calcined kaolin after dehydroxylation. Usually by grinding or fine chemical surface modification as rubber plastic and other reinforcing filler of white smoke.Shvarzman replace some found that when the amorphous phase in the kaolin is more than 55%, according to the ASTM618 standard can be used as an active filler.
