Current situation of Adhesives Market Applications

What is the new application of the adhesive industry? Such as corrosion: Ship steam pipe by package aluminum silicate to achieve adiabatic goal with asbestos, but due to leakage or alternating condensed water, gathered at the bottom of the outer wall of the steam pipe and the steam pipe; long-term high temperature, soluble salts, external corrosion is very serious. This can be used as coating material for aluminium silicate glass bottom water adhesive coating, the formation of enamel structure, thermal expansion coefficient and tube are similar, small heat stress, not chapped. In mechanical installation, the components are often fixed by bolts. Long term exposure to air by bolted devices produces crevice corrosion. In the process of mechanical work, sometimes due to violent vibration bolts loose.
In order to solve this problem, the connecting component can be bonded with inorganic adhesive before mechanical installation, and then connected by bolt. This can not only play the role of reinforcement, but also play a preservative effect. And if used as biomedical materials: hydroxyapatite Ca10 (PO4) 6 (OH) 2 (HA) inorganic composition of bio ceramic composition close to human bone, has good biocompatibility, can strong chemical bond with bone formation, is the ideal material for hard tissues. However, the prepared HA implants have high elastic modulus, low strength and poor activity. The global network has learned the phosphate glass coating adhesive, through the adhesive effect of HA powder in the sintering temperature is lower than that of the traditional bonding together, thereby reducing the elastic modulus, ensure the material activity. Cohesion technologies announced that they developed a Coseal sealing glue that can be used for heart bonding and has been used successfully in clinical practice.
By comparing 21 cases of cardiac surgery in Europe use found that using Coseal surgery than other methods significantly reduced surgical adhesions, early subsequent clinical studies show that Coseal has great potential in sealing glue, gynecology and abdominal surgery in the heart. The application of adhesive in medicine is regarded as the new growth point of adhesive industry. The structure of the glue epoxy resin or unsaturated polyester. Stealth submarines are one of the symbols of modern naval equipment modernization. An important method for submarine stealth is to install anechoic tile in submarine shell. The silencing tile is a rubber with sound absorption property. In order to realize the solid connection between the silencing tile and the steel plate of the boat wall, we should depend on the adhesive. For military areas: tank maintenance, military boat assembly, for military aircraft light bomber, missile warhead thermal bonding layer, the preparation of camouflage materials, counter-terrorism. |
