Last Tuesday, the staff of the Shanghai Electric Nuclear Power Department stated that this year will complete the production of the prototype of the wet stator stator pump of the nuclear power station Shidao Bay CAP1400 demonstration nuclear power plant. Injection Molding Machine For Auto Parts
The advantage of MYTAO press is that it can provide system solutions according to customers' product characteristics and quality requirements, including not only the whole machine system that adapts to different processes, but also mold design schemes to ensure product molding quality and provide high-quality injection molding machines. To enhance the core competitiveness of customer products
The plasticization of automobiles is a major development trend of the international automobile manufacturing industry today. The current automotive market demand has shifted to lighter sports utility vehicles, minivans and other light vehicles, which will promote the development of lighter automotive materials. The light vehicle market has a very large demand for resins such as nylon, polypropylene, polyurethane and other engineering plastics, accounting for more than 30% of the total resin market demand; the demand for polyvinyl butyral accounts for about its total demand 85% of the total.

Shanghai Electric’s above mentioned to the Great Wisdom News Agency that the completion of the manufacture of the CAP1400 wet stator main pump prototype is a key task for this year. Currently, Shanghai Electric is the only domestic manufacturer of this equipment. The equipment is mainly used in the manufacture of third-generation nuclear power projects and can be applied to nuclear power projects such as Lufeng, which are carrying out preliminary work.
According to the introduction of National Nuclear Power Technology Company, the demonstration power station is located at the Shidao Bay site of Rongcheng, Weihai City, Shandong Province. It is planned to build a third-generation passive nuclear power demonstration unit CAP1400 PWR nuclear power unit with independent intellectual property rights in China, with a design life of 60 years and a stand-alone capacity. 1.4 million kilowatts. The project is one of the 16 major science and technology projects identified by the National "Summary of the Medium and Long-Term Development Plan for Science and Technology (2006-2020)."
At present, the preliminary feasibility study documents for demonstration power plants have passed the review and the feasibility study report has been completed. According to the work plan, a work order was issued in January 2013 and the first tank concrete (FCD) was poured on April 30, 2013 and put into operation in 2017.
Plastic requirements
Excellent weather resistance, ensuring that it will not change color or aging and cracking after long-term use (including heat-resistant oxygen aging and light aging);
Good chemical resistance to resist the erosion of oil and daily chemicals;
Easy formability, sufficient fluidity for injection-grade materials, to ensure the formation of complex parts, and improve production efficiency;
Economical requires materials with high cost performance.
Material requirements for exterior parts
Weather resistance: weather-resistant materials should be used for parts that are not painted or electroplated, such as AES, ASA (AAS), PC/PBT (PET), etc.;
Heat resistance: Due to the low ambient temperature, the standard heat resistance level can meet the requirements;
Low temperature resistance: the material is required to have a certain low temperature resistance to prevent the components from cracking in the low temperature environment in winter;
Chemical resistance: to prevent the erosion of oil and acid rain;
Scratch resistance: The material is required to have a certain surface hardness and a low coefficient of friction to prevent scratches.
Material requirements for interior parts
Heat resistance: Due to long-term sunlight in summer, the temperature in the cabin is relatively high, and the interior materials are required to have high heat resistance;
Aging resistance: including thermal oxidative aging and light aging, to prevent aging, discoloration and deterioration of components;
Odor: For the health of drivers and passengers, materials should ensure low volatility and low odor;
Matte: To ensure driving safety, use matte materials or matte textures;
Scratch resistance: the material is required to have a certain surface hardness and a low coefficient of friction to prevent scratching and fluffing
