One, function
The main function of adhesive is to connect the adhesive material together. The stress transfer compared with the traditional mechanical fastening adhesive component, the stress distribution is more uniform, and the components of structural bonding than mechanical fasteners (riveting, welding, interference connection and bolt connection etc.) of high strength, low cost, light quality. If the thin pieces of adhesive bonded to the thick wall products, can give full play to all the strength of thin wall parts. The strength of the mechanical fastening and welding structure is limited by the fastener or the solder joint and the thermal induction zone.
The adhesive bonded component is smooth and smooth, and the function is not decreased. This is particularly important for structural adhesive. Such as the aerospace industry in the structure of the appearance of smooth and high flatness, which is conducive to reducing the resistance and friction, the friction temperature will be reduced to a minimum. Therefore, the helicopter rotor blades are all assembled with adhesive. Adhesive bonded with the close of the electronic or electrical components to avoid the bump, benefit from it. The navigation electric appliance uses the adhesive assembly to be possible to obtain the smooth surface without the structure interference. Because the distribution is very uniform stress in adhesive joints can be adhered to, the strength and stiffness of all embodied, but also can reduce the quality, such as spacecraft by eliminating the negative load adhesive assembly, increased payload, range increase, reduce freight.
Adhesive products can be used in metal, plastic, rubber, ceramics, cork, glass, wood, paper, fiber and other materials. When the joints of different materials are in variable temperature, the adhesive can play its unique use efficiency. Flexible rubber adhesive is adjustable thermal expansion properties of the difference, and to prevent the damage caused by the strong rigid system in use environment. If the adhesive components used in high temperature, can be suitable for adhesive products to move and transfer in different materials of different materials, effectively adjust the difference in thermal expansion between the mobile or through the migration process, to firmly bonded into one of the objective. As a result, automobile, aircraft and other windows and metal frame adhesive commonly used to complete adhesive.
Two, quality
Product quality is an important killer enterprise quickly cut into the market, enhance the sustainable development of enterprises depends on the quality to support technological innovation, to adapt to the transformation of high-end enterprises in the downstream of the upgrading of demand. The enterprise must find a breakthrough in the quality of key products, to improve product quality to promote industry transformation and upgrading of the work of the starting point, research and development, production of high value-added, high reliability products.
The quality and technology of adhesive products are closely related. Foreign companies such as 3M in the high-end market, so the quality can be guaranteed, domestic companies due to the low degree of concentration, resulting in uneven quality of products, but with the rapid development of the domestic industry and the cooperation of the domestic enterprises and foreign-funded enterprises, the quality of some technology and products can reach the leading level in the world.
Rigorous, scientific research methods to ensure the accuracy and quality of the research report. The main research methods used in the Research Report on the project investment and the competitiveness of China's adhesive industry in 2013-2017:
1 census: we have nearly one hundred practitioners in the adhesive industry for a face-to-face interview or telephone access, access to the best first-hand data.
2 tracking research: in order to ensure the real-time grasp of the adhesive products industry dynamics, we have established a tracking mechanism in the adhesive products industry, access to the adhesive products industry development trends.
3 (government) data: we have inquired about the industrial and commercial archives of the key enterprises of the adhesive products industry, the Bureau of statistics, the customs import and export data, and so on.
4) SOWT analysis: SWOT analysis, Potter five forces analysis method, we analyzed the adhesive products industry and enterprise competition advantages and disadvantages and potential threats and opportunities.
5 scientific prediction: we use regression analysis, time series analysis, factor analysis, combination analysis and other methods to make a full prediction of the development trend of adhesive products.
