Coating classification: polyurea

Core tip: the product is a kind of compound formed by the reaction of isocyanate component and amino compound Isocyanate components can be monomers, polymers, isocyanate derivatives, prepolymers and semi prepolymers Polyurea can be polymerized from diamine, diisocyanate or urea Polynonylurea is a representative polyurea polymer The product is made by condensation of nonyl diamine and urea Its properties are similar to that of polyamide (such as nylon 6) It can be melt spun The melting temperature is 230 ℃ ~ 235 ℃, and the density is small (1.066 g / cm3) It has good heat resistance, dyeability and corrosion resistance 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 Paint Home News: product description by isocyanate components and amino compounds reaction generated a class of compounds Isocyanate components can be monomers, polymers, isocyanate derivatives, prepolymers and semi prepolymers Polyurea can be polymerized from diamine, diisocyanate or urea Polynonylurea is a representative polyurea polymer The product is made by condensation of nonyl diamine and urea Its properties are similar to polyamide (such as nylon 6), and it can be melt spun The melting temperature is 230 ℃ ~ 235 ℃, and the density is small (1.066 g / cm3) It has good heat resistance, dyeing and corrosion resistance The tensile strength of the fiber is 0.0441 ~ 0.0539 n / Dan, and the elongation is 23% It is suitable for making fishing nets and knitwear Product characteristics 1 no catalyst, fast curing, can be sprayed on any curved surface, inclined plane and vertical surface, does not produce flow phenomenon, 5 seconds gel, 1 minutes to reach the walking intensity 2 Not sensitive to moisture and humidity, not affected by environmental temperature and humidity during construction 3 Two component, 100% solid content, friendly to the environment; 4 The thickness of the construction meets the requirements, overcoming the disadvantages of the previous multi-layer construction 5 Excellent physical properties, such as tensile strength, flexibility, aging resistance, medium resistance, wear resistance, etc 6 It has good thermal stability, can be used for a long time at 150 ℃ and can withstand a short-time thermal shock of 350 ℃ 7 Various colors and fillers can be added to make products of different colors 8 The formula system can be adjusted at will, with the hand feeling from soft rubber (Shao A30) to hard elastomer (Shao D65) 9 Use complete set of spraying and pouring equipment, convenient construction and high efficiency 10 The equipment is equipped with a variety of switching modes, which can be sprayed or poured The technical advantages of the product are as follows: 1 The coating is dense, continuous and seamless, and the protective performance is very outstanding; 2 The material protection and spraying technology are organically combined to greatly improve the quality and progress of the project; 3 The color is gorgeous and can be adjusted at will, which will completely change the appearance of "yellow water" of Chinese steel structure; 4 The construction speed is fast, one equipment needs 3-4 people to operate, and it can be constructed over 1000 square meters every day, 15-20 times of the traditional technology, minimizing the impact of weather on the construction progress; 5 The material has good flexibility, high strength, corrosion resistance and aging resistance, and can be used outdoors for 10-20 years; 6 In construction and use, it is non-toxic and pollution-free, known as "green material and green technology" The home of product construction process coating is focused on the news and information of coating, diatom mud, paint coating, coating process, fire retardant coating, coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fire retardant coating,
