Due to the financial crisis last year, the machine drag chain industry has many characteristics, mainly including: 1. The adjustment of the product structure of the enterprise has made great progress, 2. The independent innovation achievements are remarkable, 3. The fixed assets investment grows rapidly, 4. The enterprise management The way to start changing. The production efficiency has been greatly improved, the manufacturing cost has been reduced, and the service for the user base has been further strengthened. However, it also caused some deep contradictions in the industry to become more prominent, making the leading products of production incompatible with the needs of national economic development. Therefore, in the next year, the entire industry must accelerate structural adjustment and change the development mode to create conditions and environment for the healthy and sustainable development of the industry. For the reform of the machine tool chain: First of all, we must further accelerate the structural adjustment of machine tools, eliminate outdated products and equipment, and produce high-quality products. Once again, it is to further improve the industrial chain, increase policy support, break through the bottleneck of the machine tool drag chain industry, and develop high-grade abrasive abrasives and super-hard materials and products. The second is to implement corporate restructuring. Then it is to improve the professional production level of the production industry, improve the utilization rate and productivity of materials, and reduce energy consumption and pollutant emissions. Finally, the industry's import and export trade structure is adjusted. The machine tool towline industry is the last year of the implementation of the 11th Five-Year Plan in the next year. It is also a relatively crucial year, making new contributions to the machine tool industry to accelerate structural adjustment and transform the development mode.
There are two ways for paper sizing, one is in front of the sheet forming (beating or ingredients) add sizing agent in pulp called intracytoplasmic sizing, another is in sheet forming after coating on paper or cardboard surface is called the surface glue.The sizing agent of pulp is mainly rosin sizing agent, synthetic sizing agent, paraffin sizing agent and neutral sizing agent.Surface sizing agent and neutral sizing agent.Surface sizing is mainly to improve the smoothness of the surface of the paper, reduce the porosity and prevent the surface hair and hair loss.The more used is modified and unmodified starch, and the PVA is also used.Other products include paraffin emulsion, animal glue, carboxymethyl cellulose, polyurethane, styrene-maleic anhydride copolymer, acrylate copolymer, dihydroxy fatty acid compound, etc.
