Spunbond Nonwoven Production Line The polyester PET non-woven production line is used for the production of non-woven fabrics such as polypropylene spinning, web forming, and hot rolling reinforcement. Using polypropylene as the main raw material, supplemented by color masterbatch, anti-oxidation, anti-pilling, flame retardant and other auxiliary agents, it produces PP spunbond hot-rolled non-woven fabrics with different colors, properties and uses, and polyester spunbond and hot-rolled non-woven fabrics. It has the excellent characteristics of high strength, low shrinkage, heat resistance, good stability, breathable waterproof, flame retardant, acid and alkali resistance, moth-proof, non-toxic and anti-ultraviolet.

The deepwater test pond construction project is an internationally advanced deepwater test technology facility that can simulate various marine environments such as wind, waves and currents, and test various performances of offshore platforms and ships in harsh marine environments for them on the ocean. The safe operation provides scientific basis and can meet the needs of simulation test of deep sea resource development projects such as oil, natural gas and polymetallic nodules, as well as the research and development of deep sea submersibles, underwater pipelines and maintenance.
Recently, the Shanghai Deepwater Test Pool construction project of Shanghai Jiaotong University, which was built by Shanghai Tunnel Engineering Co., Ltd., entered the pouring stage of the large floor of the pool. According to relevant parties, the pool has the ability to simulate a water depth of 4,000 meters and various complex marine environments, comparable to the most advanced Dutch MARIN pool in the world. It is expected that the project will be completed next year, when the first simulation "ocean" will appear in Shanghai.
The deep water test pond is located in the east campus of Jiaotong University. The deep pool consists of a pool body and a deep well. The pool is 50 meters long, 40 meters wide and 10 meters deep. The deep well in the center is 40 meters deep and 5 meters in diameter. The construction precision is extremely high. . At the site of the construction site, the concrete is poured into the pool without interruption for 50 hours. After the casting of the floor is completed, the underground structure of the project is basically completed, and the upper structure of the building will be followed.
The simulation of "ocean" is not easy to make. The pool floor area is 2,000 square meters and there are almost two pool sizes. The central deep well is deep and narrow, and within a circular area of ​​only 5 meters in diameter, it is necessary to dig a large area of ​​40 meters for the "ocean". In addition, the engineering requirements are strict, the inclination of the inner wall of the pool and deep well shall not exceed 1‰, the waterproof coefficient of the project shall be one level, and the material must have high strength and good impermeability.
