The continuous growth of domestic wood flooring exports has played a positive role in promoting the development of the national wood flooring industry. It has also provided strong support for domestic wood flooring to establish a national flooring brand and enhance overall competitiveness. In recent years, China's wood flooring industry has developed rapidly and rapidly in terms of process standards and varieties of flowers, and has become a hot commodity in the international market. The export is mainly concentrated in western countries with relatively developed economy and high living standards. The floor is waxed at intervals. The time interval depends on the finish of the floor. The method is to wipe the floor with a semi-dry cloth and evenly apply the wax to the floor surface. After a little dry, wipe it with a dry soft cloth until it is smooth and translucent. until.
In the first nine months of the year, the total amount of wood flooring exported to the United States, Canada, Japan, and the United Kingdom accounted for nearly three-quarters of the total export of wood flooring in China. From the perspective of the varieties of wood flooring for export, the export of wooden parquet flooring is unique and dominates. The export volume in the first nine months has exceeded 70% of the total export volume. At present, China's manufacturers of wood flooring for export are distributed in more than 20 provinces, cities and regions across the country.
According to industry insiders, the recent increase in the export of domestic wood flooring has a direct relationship with the following factors: the parquet floor is popular in the international market, the floor export volume exceeds the expected industry mature, the equipment is advanced, the product quality is high after nearly 10 years of development, China's flooring The production industry has grown from weak to strong, gradually forming a large and comprehensive mature industrial chain. At present, there are about 350 domestic laminate flooring manufacturers and more than 440 production lines. The output this year is expected to reach 18 million cubic meters, an increase of 19% over last year.
Through the cooperation of domestic and foreign capital, the introduction of foreign advanced technology in the same industry, and the vigorous research and development of new products, many domestic wood flooring processing and production enterprises have reached the international advanced level, especially in the field of laminate flooring production. Its production level and innovative ability, its products are in the leading position in the world, and are widely welcomed by foreign markets. The domestic wood flooring export has obvious price advantage. It is known through interviews with domestic flooring manufacturers that the price of domestically produced laminate flooring with good quality for export to Canada is 5-6 US dollars per square meter, and the products of low quality small and medium-sized manufacturers are only per square meter. 3 to 4 US dollars, domestic wood flooring even if it is sold abroad by local distributors to more than 20 US dollars per square meter sold still has a more obvious floor price advantage.
Many consumers in the West have a special liking for Chinese-made wood flooring with high quality and low price, variety and environmental protection indicators, and have become a European and American family without any doubt.
The first choice for renovation and upgrading. The tariff preference policy is relatively stable and the RMB exchange rate is relatively stable. It is a strong domestic export of wood flooring. At this stage, China implements a zero-tariff policy on log imports and an export tax rebate subsidy for wood flooring products. The two preferential policies have greatly encouraged the expansion of domestic wood flooring enterprises. The enthusiasm of exports.
In addition, the exchange rate of the RMB against the US dollar has remained relatively stable; while the price of the euro has remained high during the same period, objectively increasing the price advantage of domestic wood flooring over European products. Policy subsidies attract many SMEs to join the production of wooden flooring to maximize the protection of China's existing forest resources, encourage scientific treatment and utilization of forest waste, the state has implemented a "special policy", stipulates that "all wood flooring production The enterprise grants a certain amount of subsidies to enterprises that use or use urban waste (such as waste furniture, waste wood doors and windows, waste wood packaging materials, etc.) or branches and coffins. This subsidy is limited to enterprises that meet the "policy regulations". Not all companies, but not much, but for the real wood flooring manufacturers, it is an unexpected surprise.
Black metal industry standard of the People's Republic of China: Ultra High Power Graphite Electrode (YB/T 4090-2000) "regulation of the ultra High Power Graphite Electrode shape, size and allow deviation, technical requirements, test methods, inspection rule, packing, marking, storage, transportation and quality certificate. It is applicable to high - power Graphite Electrode, which is made of high quality needle coke as the main raw material, which is made of molding, roasting, impregnating, graphitization and machining.
Graphite is very common in nature, and graphene is the intensity of the highest substance known to mankind, but scientists could still take several years or even decades, to find a way to graphite into a large high quality graphene "thin film" method, thus they can be used to manufacture all kinds of useful material for mankind. According to scientists, graphene in addition to very strong, but also has a series of unique features, graphene or conductive performance of the best known materials, which makes it also has great potential applications in the field of microelectronics. The researchers even see graphene as a substitute for silicon that can be used to produce future supercomputers.
superiority
1: the increasing complexity of the geometry of the mould and the diversification of the product application result in the higher and higher demand for the discharge accuracy of the spark machine. The advantage of graphite electrode is that it is easy to process, high removal rate and low graphite loss. Therefore, some of the group spark machine customers have abandoned copper electrode instead of graphite electrode. In addition, some special shaped electrode can't made of copper, but easier to forming, graphite and copper electrode is heavier, not suitable for processing large electrode, these factors have caused part of the group of the graphite electrode spark machine customer applications.
2. Graphite electrode is easier to process, and the machining speed is obviously faster than that of copper electrode. For example, graphite is processed by milling process, and its processing speed is 2~3 times faster than that of other metals, and no additional manual processing is required, while the copper electrode needs to be worn by hand. Similarly, if you use a high speed graphite processing center to make the electrode, it will be faster, more efficient, and will not produce dust problems. In these processes, selecting the right tools and graphite can reduce the abrasion loss of the cutter and the breakage of the copper gong. If the concrete is the milling time of graphite electrode copper electrode and graphite electrode, graphite 67% faster than copper electrode, in the general case of electro discharge machining, the adoption of graphite electrode machining 58% faster than using copper electrode. In this way, the processing time is greatly reduced and the manufacturing costs are reduced.
3: the graphite electrode is different from the traditional copper electrode design. Many mold factory in copper electrode roughing and finishing usually have different requirements, and graphite electrode is used almost the same amount of reserve, this reduces the CAD/CAM and the frequency of machine, sheet is for this reason, to a large extent is enough to improve the precision of the mold cavity.
Of course, the first thing that should be clear is how to use graphite materials and other related factors after the copper electrode is transferred to graphite electrode. Today, some group spark machine customers use graphite for electrode discharge machining, which is exempt from the process of mold cavity polishing and chemical polishing, but still achieve the desired surface finish. If the process of time and polishing is not increased, it is impossible for the copper electrode to produce such an artifact. In addition, the graphite is divided into different levels, and in particular the application of using the appropriate level of graphite and spark discharge parameters to achieve the ideal processing effect, if in the use of graphite electrode spark machine operators use the same as the copper electrode parameters, then the result is certainly disappointing. If the material of the electrode is strictly controlled, the graphite electrode can be used in the non-loss condition (less than 1%), but the copper electrode is not used.
