Sss Spunbond Nonwoven Production Line
SSS: Spunbond non-woven fabric + spunbond non-woven fabric + spunbond non-woven fabric = 3 layers of fiber web hot rolled; S non-woven fabrics, SS non-woven fabrics, SSS non-woven fabrics can be produced, according to non-woven fabrics Cloth performance can be used for: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wipes, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloths Cloths, tablecloths, bed sheets, bedspreads; clothing linings, fusible linings, wadding, shaped cotton, various synthetic leather base fabrics, industrial filter materials, insulating materials, cement packaging bags, geotextiles, covered cloths, crop protection cloths, seedling cloths , Irrigation cloth, thermal insulation curtain, other space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc. Mainly used in disposable hygiene products industry, medical health industry, beauty care and other industries.In terms of environmental protection, the raw material of most of the non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded , And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bag can be reused more than 10 times, and the pollution degree to the environment after being discarded is only 10% of that of the plastic bag.

Since the beginning of the new century, domestic mining enterprises have entered the fast track of rapid development, and mining of large-scale open pit mines with a capacity of more than 10 million tons has made high-end heavy-duty mining equipment face a broad space for development. The development prospects of large-tonnage electric wheel dump trucks are very promising. After investigation and verification, the Fourth Hospital cultivated heavy engineering equipment as a key project at the college level. In February 2011, the four hospitals seized the opportunity of the cooperation between China Aerospace Science and Technology and Datang Group to sign a strategic cooperation agreement and signed a contract for the development of large-tonnage dump trucks with Datang Xilinhaote Mining Company. Subsequently, the institute successively established the Heavy Engineering Equipment Design Institute and Aerospace Heavy Engineering Equipment Co., Ltd., which specializes in R&D, production, and operation of heavy equipment, and established the business of R&D, capacity building, application for policy support, and marketing of heavy mining equipment. The main body of implementation.
After two years of research and development and more than four months of assessment tests, 220 tons of new energy-saving multi-axis heavy mining dump trucks have been officially delivered to Inner Mongolia Datang International Xilinhaote Mining Co., Ltd. Currently, Siyuan is actively developing complementary products around heavy industry projects.
220 tons of dump trucks delivered to break the import dependency of large-tonnage dump trucks
On July 16, the editors learned from China Aerospace Science and Industry Corporation that 220 tons of new energy-saving multi-shaft heavy-duty mining dump truck independently researched and developed by the fourth hospital of the group had been successfully delivered, which broke the long-term dependency of foreign heavy-duty dump trucks on foreign imports. The situation indicates that China's large-scale open-pit mine transport equipment manufacturing technology has reached the world's advanced level. The hospital has thus become one of the few companies in the world that can produce this type of heavy mining dump truck.
