1. There are many factors that affect the reinforcement effect. From the perspective of the matrix material, including raw materials (composition, particle size), proportion (additives) and gel solidification process. Pay attention to the glass fiber reinforced substrate:
1. Choose glass fiber varieties for the reinforced matrix material and its gelation process. For example, high-alkali glass fiber must not be used in the hydrothermal synthesis process, and alkali-resistant glass fiber should be selected for the large amount of Ca (OH) 2 precipitated.
2. Discuss the amount of glass fiber added with the reinforced cement material products company and how to distribute it evenly in the matrix before solidification to form a reasonable reinforcement network. It is also possible to consider coating the surface of the glass fiber to improve the corrosion resistance of the glass fiber and the "cracking" effect in such porous solid brittle materials.
3. In the board and other products, the alignment of the glass fiber reinforced substrate must be considered, including the selection of the structural form of the glass fiber substrate (such as felt, mesh) and the coordination (surface layer or middle layer) in the product to improve the product's Overall performance.
At present, this kind of glass fiber substrate must first ensure that the product quality is stabilized according to the specifications within the scope of use, and on this basis, it will steadily improve to prevent self-destruction.
Strive to develop together with the composite material industry chain 1. The scientific development of the "industrial chain" and "value chain" is a concept that summarizes the coordinated development of modern economy. Many economic experts and entrepreneurs have made in-depth explanations.
Composite materials have their own characteristics. Relevant experts point out that, relative to a single material, "composite materials are structures", and its materials are manufactured together with products, which have composite effects and coupling effects. "Composite material technology covers 5 aspects such as design, process, material, equipment and testing", and of course also involves the application of products. Based on this characteristic of composite materials, more attention should be paid to the "industrial chain", and some industry experts called for the coordinated development of the "industrial chain" and "value chain" of composite materials.
On the tenth anniversary of the EU Fiberglass Manufacturers Association, its Secretary-General emphasized the use of glass fiber as a link in the composite material chain, and used the overall advantages of EU composite materials to compete with China's low-cost glass fiber products. This also gives us a good inspiration for the development of the glass fiber industry, which is mainly used as a reinforcing material for composite materials.
Second, to accelerate innovation and improve product quality To better develop China's glass fiber-reinforced substrates, we must accelerate technological innovation, improve product quality and expand product categories to meet the needs of composite materials development. In this direction, each enterprise pays attention to the establishment of an innovation mechanism, creates an innovation atmosphere, formulates an innovation plan, and implements innovation measures.
The technological progress of each enterprise must be based on the specific conditions and development goals of the enterprise, and strive to have high standards and characteristics. In the broad field of composite materials, it is important to choose a specific field and a certain type of reinforced base material to determine the direction, objectives and steps of technological progress in a concrete manner. It is important to give full play to the existing technical expertise. Experts point out that core competitiveness often comes from the long-term accumulation of a certain professional field, so pay attention to the successful professional accumulation of the company itself, and avoid "following the trend" and "breaking the stick". The extent of technological progress can be greater and better, but not large but small. The key is to do well, to be refined, to be specialized, and to strive for good results. The combination of the expertise and expertise of each enterprise is the improvement of the overall level of China's glass fiber reinforced substrate.
3. To meet the demand of the domestic market for glass fiber 1. The current domestic glass fiber market is booming. To meet the domestic market demand to the maximum extent is one of the main purposes of the development of the glass fiber industry in China, and it also meets the requirements of national policies. The key is to focus on solving the problems of application technology and domestic market operation (such as market fragmentation and price, arrears, etc.) that connect production and market.
2. Pay close attention to advance in production. China still needs to import more than 200,000 tons of glass fiber products every year, which is an obvious reflection of the domestic glass fiber demand, especially the quality can not meet the requirements of downstream products. Large and medium-sized enterprises in the industry should work harder to increase production. . At present, our imported products are mainly: glass fiber yarns for special cylinders, electronics, etc .: high-performance glass fiber fabrics for FRP blades and electronic cloth; high-performance reinforced thermoplastic chopped fiber and glass fiber yarns for LFT.
3. Expand the application fields according to the characteristics of glass fiber: â‘ consolidate the original traditional fields: thermal insulation, traditional reinforced base materials, building decorative materials, electrical insulation materials, filter materials, etc., and pay attention to improve the series of supporting equipment and continue to develop new products. â‘¡Develop new fields: new-type reinforced base materials, materials for energy field, materials for anti-corrosion, etc.
Fourth, look at the trend, follow the trend, and accelerate the development of new products. According to domestic and foreign market trends, there are currently three main efforts:
1. At present, China's large-scale wind power blade glass fiber substrates, high-quality high-pressure winding yarns, and LFT yarns are basically imported, and localization development will be carried out soon.
2. Improve the export grade of glass fiber products. This is also a requirement for the country to adjust its export structure. On the basis of a large share of the export of traditional reinforced substrates of yarn, felt, and checkered fabrics, we must adapt to the new requirements of FRP closed-mold molding for increasing the demand for glass fiber reinforced substrates, and accelerate the development of glass fiber warp knitted substrates and seams. Weaving base materials, composite base materials, woven base materials, narrow width base materials and other products, and making the product quality meet international standards, so as to gradually increase the export share and increase the value of foreign exchange.
3. With the strengthening of building energy saving requirements and the expanded use of new lightweight building materials, pay attention to the development of new applications of glass fiber in the construction field, such as reinforced gypsum, reinforced magnesite, sunshade, textile building materials, etc. potential market.
Fifth, strive to do a good job in application development services. It should be said that we have a large gap with foreign countries in this respect. Most of our companies only pay attention to the sales of their own products, and the after-sales service is relatively shallow. There are three points for learning advanced foreign experience:
1. There must be sufficient integrity and guarantee in terms of stability and quality improvement.
2. Personalized services according to user requirements, develop a series of specialized products, such as FRTP products can be divided into different types of products of enhanced objects and molding processes.
3. Foreign companies all provide "solution" services. If users want to use materials to make a certain product, material production companies must propose a "solution", including recommending materials produced by enterprises, or even producing modified products for users. Materials, not only
