目前我国的沙法生产,以弹簧沙法为主。其用料品种多、工艺复杂、劳动强度大。为改变沙法生产的落后状况,努力探索和采用新材料、新工艺,赶上世界先进水平。盐城地区新能源研究所在上海同济大学、南京大学等单位的协助下,试制成一种充气沙法(见图)。充气沙法由气垫包和支架组合而成。气垫包内为气囊,外部面料采用人造革(亦有纤维织物)。支架有组装式和折叠式两种,材料有金属的亦有木质的。充气沙法的用料立足于我国的资源情况,气囊采用塑料薄膜热合工艺,为克服塑料薄膜的成园性,增强强度和稳定性,气囊内附加了数根分仓筋,气囊采用双重气密装置,充气方便,存气 At present, the production of sand in China is dominated by spring sand method. The variety of materials used, complex technology, labor-intensive. In order to change the backwardness of Shafa production and make efforts to explore and adopt new materials and techniques, it will catch up with the world’s advanced level. Yancheng Institute of New Energy in Tongji University in Shanghai, Nanjing University and other units with the help of trial, made an inflatable sand (see photo). Inflatable sand law by the air bag and bracket combination. Airbag bag for the airbag, the outer fabric with artificial leather (also fiber fabric). Bracket has two kinds of assembly and folding, the material is also a wooden metal. Inflatable sand method of materials based on the resources of our country, the airbag plastic film heat sealing process, in order to overcome the plastic film into a garden, enhance the strength and stability, the airbag attached to the number of sub-warehouse bar, double airbag airbag Device, easy to inflate, keep gas
