由我院和铁道部第十五工程局联合研制的WSFG型维纶塑胶布系列通风软管于1994年6月通过了由铁道部建设司、中国铁道建筑总公司组织的鉴定。鉴定意见一致认为: 1.WSFG型维纶塑胶布系列通风软管选用PVC维纶纤维塑胶布作为风管材料,具有防水、阻燃、抗静电性能;用塑焊工艺取代缝纫法加工通风软管,避免了缝纫针眼漏风的可能性;风管钢制接头采用包覆式捆绑结构,风阻较小,密封可靠,接管方便。该通风软管的技术参数性能指标达到了国家、行业技术标准。
The Ventilation Hose of WSFG vinylon series developed by our institute and the 15th Engineering Bureau of the Ministry of Railways passed the appraisal by the Construction Department of the Ministry of Railways and China Railway Construction Corporation in June 1994. Identification of the unanimous view that: 1.WSFG Vinylon plastic sheeting series ventilation hose selection PVC vinylon fiber plastic sheeting as duct material, with waterproof, flame retardant, antistatic properties; plastic welding process instead of sewing ventilation hose processing, to avoid The possibility of needle-hole leakage; the wind pipe steel joint covered with bundled structure, the wind resistance smaller, reliable sealing, easy to take over. The technical parameters of the ventilation hose performance indicators have reached the national, industry technical standards.
