    As a kind of high molecular carbohydrate, starch contains a lot of active groups, which can be modified by physical or chemical methods to give starch special properties and make it more suitable for certain application requirements With the development of chemical modification technology, the exploration of starch graft copolymer has become an important topic in starch research 。 Grafting starch is to activate starch macromolecule by chemical or high-energy ray irradiation, so that the desired oligomer can be connected to starch macromolecule as a "branched chain" Starch formed by graft copolymerization - a new functional polymer material Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and coating Home news: as a kind of high molecular carbohydrate, starch contains a large number of active groups Starch can be modified by physical or chemical methods, which can give starch special properties and make it more suitable for certain application requirements With the development of chemical modification technology, the exploration of starch graft copolymer has become an important topic in starch research Grafting starch is to activate starch macromolecule by chemical or high-energy ray irradiation, so that the desired oligomer can be connected to starch macromolecule as a "branched chain" Starch was grafted and copolymerized to form a kind of new functional polymer material The main uses are as follows: (1) it is used as a water absorbent, which is added to the material to be dried, and the water content of the material is removed by using the characteristics of its hydrophilic starch group (2) As a flocculant, organic flocculant has the advantages of economy and simple usage Compared with the traditional flocculant, it can improve the efficiency many times, and the price is lower, so it has the trend of becoming the mainstream flocculant gradually In addition, the product quality is stable, and the production of organic polymeric flocculant has accounted for 30% - 60% of the total production of flocculant (3) As super absorbent resin, when it is in contact with water, it will absorb water and expand in a short time, and keep in the body It has excellent water absorption and water retention capacity When extruding a polymer that has absorbed water and expanded, it only releases a small amount of water and maintains excellent water retention capacity It remains stable when heated or exposed to ultraviolet light It's almost non-toxic. (4) As starch based plastics, starch based plastics is to use chemical reactions to modify starch, reduce the hydroxyl of starch, change its original structure, change the corresponding properties of starch, and change the original starch into thermoplastic starch (5) As a new thickener The thickening mechanism of polyacrylic acid thickener is that the thickener dissolves in water, through the same-sex electrostatic repulsion of carboxylate ion, the molecular chain extends from spiral to rod, thus improving the viscosity of water phase In addition, it also increases the viscosity of the system by forming a network structure between latex particles and pigments (6) It is used as a dry strength agent in papermaking Most of the synthetic dry strength agents are hydrophilic polymers, which increase the amount of bonding between fibers and improve the paper strength Most of the dry strength agents contain cationic groups attached to the main chain ring, which increases the binding force between the polymer and the fiber and improves the retention of the polymer Dry strength agent is a kind of important chemicals to increase the paper strength in the paper industry Many water-soluble polymers which can form hydrogen bond with fibers can be used as dry strength agents The dry strength agent is usually used to compensate for the decrease of paper strength caused by the addition of fillers or low-grade fibers (such as recycled fibers) [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
