refractory
Flake graphite is widely used in the treatment of gold industry of advanced refractory materials and coatings. Such as magnesia carbon brick, crucible, etc. Military industrial firework material stabilizer, smelting industrial desulfurization growth agent, light industry lead pen, electric industry carbon brush, battery industry electrode, fertilizer industry catalyst and so on. The flake graphite is deeply processed, and it can produce the graphite milk for lubricant, deformable agent, drawing agent, conductive coating and so on. It can also produce Expanded Graphite for flexible graphite products such as flexible graphite seals and flexible graphite composite products.
dope
The flake graphite as the functional filler of coating is mainly used for anticorrosive coating, fire retardant coating and conductive coating.
As an anticorrosive material, it has anti-rust primer, such as carbon black, talcum powder and oil, which has good corrosion resistance of chemicals and solvents. If you add zinc and yellow to the formula, it is better to rust.
A graphite interlayer compound obtained from Natural Graphite scales as raw materials, chemically or electrochemically treated. Expandable graphite under the condition of heat, swelling volume (up to 300 times) suffocate the flames, at the same time generate inflation, to isolate the flame, delay or interrupt the effect of flame spread, and itself does not burn, good flexibility, high surface energy, intensity of carbonized layer. But the volume and dosage of the expansive body should be suitable. The test shows that the 150um particles, 30% expansion multiples and 5% dosage are the most suitable.
The flake graphite can be directly used as a carbon conductive filler and can be made into a composite conductive filler for conductive coatings. However, due to the large addition of graphite flake, the coating can be brittle and its application is limited. Therefore, measures are taken to further improve the conductivity of graphite and effectively reduce the amount of graphite flake. Our domestic chemical machinery research institute has developed a high temperature and corrosion resistant resin as basic material, with the strong ability of conducting electrostatic entities large flake graphite flake as the main aggregates, with high intensity of ontology Good abrasion resistance.
The anti - deformation cracking - good short - cut fiber material is a solvent - free thick film conductive coating. The coating has the characteristics of anti-corrosive media penetration, small residual stress, good anti-matrix deformation, stable construction performance and long - term conductive static. Can be used in oil tank inner wall guide electrostatic coating. With electroless plating technique, according to the data of graphite powders metallized, such as copper, nickel, silver, such as the preparation of composite conductive filler, with 30% of the amount used in conductive coating, not only its conductivity is very good, and further improve corrosion.

According to statistics, China's hardware lock industry has been developing steadily at an annual growth rate of 15%. The annual total output value has reached more than 180 billion yuan*** and exports have reached more than US$8 billion. It accounts for about one-third of China's total light industry exports, ranking the top three in light industry.
The hardware lock market continues to heat up In recent years, with the rapid development of China's hardware market, the lock market has taken a turn for the better. The overall capacity of the lock market has reached 70 billion, and Zhejiang, Guangdong, Shanghai and Shandong are the manufacturers of locks. The main focus. The lock market has become more and more characteristic. The characteristics referred to here are the development model of industrial clusters. The number of lock-making enterprises in the cluster is large and the comprehensive output of enterprises is large. The cluster lock market has a strong growth momentum, high sales, a high proportion of export growth, and imports. The speed is also increasing, and the international market share of high-end locks industry is also increasing.
At present, the annual sales of locks in the country can reach as many as 2.2 billion, and the market demand for fingerprint locks can reach 5 million per year, for example, for corporate finance, military police stations, and office life. At the same time, the demand in the civilian market is also growing. Whether it is traditional mechanical locks, or modern electronic locks, and even the current access locks in high-rise buildings, China's lock industry as a whole is developing irresistibly. The increase in the production and consumption of locks in China is a fact that is obvious to all. The domestic lock industry has annual sales of more than 400 billion yuan, and the production capacity exceeds 2 billion sets. The annual export volume exceeds 10 billion yuan.
It is reported that in the future China's lock market will continue to grow at a rate of more than 20% per year. With this strong trend continuing, the future of the lock market is inconceivable. The variety of locks and the richness of the market highlight the necessity of the development of the lock market. Creating a labor-intensive and characteristic industry with high thresholds, high specialization, and high-end locks is the only way for China's lock industry in the future.
More and more hardware lock styles With the warming of real estate and the acceleration of urban processes, it has greatly stimulated the consumer demand of the decorative hardware market. Although a small decoration hardware is inconspicuous, but the product function style is more and more optimized and refined, the variety of species, style contests.
There are more and more styles of hardware locks, many of which look more like one or a small animal, but its function is a lock. In the market, the more popular civilian locks are mainly spherical, three-bar type circular cover handles, embedded long cover door locks, and lock body handles. The other trend that is most used in the inner door is the channel and the auxiliary lock (the most important feature of the anti-theft function). The author learned from the market that the currently available locks are mainly brass, stainless steel, and bronze. The treatment of surface color is mainly a combination of two color combinations. In terms of price, the door lock is generally more than 100 yuan, expensive to 800 yuan or more; inside the room lock is relatively cheap, 80 yuan can buy a good lock.
Future development of locks â—‡ Development of high-grade locks The market prospects for high-end locks are optimistic. Because high-end locks have high technical content and are more humanized and personalized, their product profits are also relatively high. Should increase investment in high-tech locks and promote the structural upgrading of China's lock industry.
The implementation of brand-name strategic locks industry well-known companies and brands can produce huge economic and social benefits, and now China's locks face more severe challenges, competition prompted companies to respond positively, so that China's production from locks to power from a big country.
