Coating knowledge: current situation of adhesive market application

Core tip: what's the new application in adhesive industry? For example, anti-corrosion: ship's steam pipe mostly uses aluminum silicate coated with asbestos to achieve the purpose of heat insulation, but due to leakage or alternate cold and hot condensation water, gathered on the outer wall of the steam pipe at the bottom layer; and the steam pipe is subject to high temperature and soluble salt for a long time, the outer wall corrosion is very serious For this reason, a series of water glass adhesives can be used as coating materials to form a coating of enamel like structure The coefficient of thermal expansion is similar to that of the pipe, the thermal stress is small, and the coating will not be chapped In mechanical installation, members are usually fixed by bolts The devices fixed by bolts are exposed to air for a long time, which will produce crevice corrosion On machine 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: what new applications appear in the adhesive industry? For example, anti-corrosion: the steam pipe of ships mostly uses aluminum silicate coated with asbestos to achieve the purpose of thermal insulation, but due to leakage or alternate cold and hot condensate, it gathers on the outer wall of the steam pipe at the bottom layer; and the steam pipe is seriously corroded due to the effect of high temperature and soluble salt for a long time For this reason, a series of water glass adhesives can be used as coating materials to form a coating of enamel like structure The coefficient of thermal expansion is similar to that of the pipe, the thermal stress is small, and the coating will not be chapped In mechanical installation, members are usually fixed by bolts The devices fixed by bolts are exposed to air for a long time, which will produce crevice corrosion In the process of mechanical work, bolts are sometimes loosened due to severe vibration In order to solve this problem, the connecting components can be bonded with inorganic adhesive first, and then connected with bolts In this way, it can not only strengthen but also prevent corrosion Another example is for biomedical use: hydroxyapatite CA10 (PO4) 6 (OH) 2 (referred to as HA) bioceramics, whose composition is close to the inorganic component of human bone, has good biocompatibility, can form a solid chemical combination with bone, and is an ideal substitute for hard tissue However, HA implants have high elastic modulus, low strength and poor activity Global coating network learned to select phosphate glass adhesive, through the role of adhesive, ha raw material powder is bonded together under the traditional sintering temperature, thus reducing the elastic modulus and ensuring the material activity Cohesion Technologies Limited has announced that they have developed a Coseal sealer that can be used for heart bonding and has been successfully used in clinical practice In Europe, the comparative use of 21 cases of cardiac surgery found that the use of coseal surgery significantly reduced surgical adhesions compared with other methods Subsequent preliminary clinical studies showed that coseal sealing glue has great development potential in heart, gynecology and abdominal surgery The application of adhesives in medicine is known as the new growth point of adhesive industry A structural glue consisting of epoxy or unsaturated polyester In modern national defense technology, stealth submarine is one of the symbols of navy equipment modernization An important method of submarine stealth is to lay anechoic tiles on the submarine shell Anechoic tile is a kind of rubber with sound absorption performance In order to realize the firm combination of anechoic tile and boat wall steel plate, it depends on adhesive Used in the military field: tank maintenance, military boat assembly, light bomber for military aircraft, missile warhead thermal protective layer bonding, preparation of camouflage materials, anti-terrorism and anti-terrorism Focus on the WeChat official account "paint net"; pay close attention to surprises and scan the code to see "this is the most ruthless revenge": the 92525666: the paint house is focused on coatings, diatom mud, paint and coatings, coating technology, fire retardant coatings, news information and coatings, diatom mud, paint and coatings, coating technology, fire retardant coatings decoration knowledge and decoration effect map.
