白铁风管对材料有哪些要求?

来源:http://www.doqa19.com 日期:2019-07-09 发布人:admin

  风管在生产过程中对材料的要求是相当讲究的。当风道的表层是由铝箔,为了确保表层不容易损坏,铝箔规定的材料和厚度,铝箔的厚度和表面增强材料复合风道规定。
  The material requirements of air ducts in the production process are quite particular. When the surface of the duct is made of aluminium foil, in order to ensure that the surface is not easily damaged, the material and thickness specified by the aluminium foil, the thickness of the aluminium foil and the composite duct specified by the surface reinforcement material are required.
  其次,薄钢法兰通风管道内外面层与内部保温材料粘结牢固是保证复合材料的基本条件之一。超过一定面积的板缺陷,不仅影响管道的使用寿命,有时还会降低其保温效果。因此,该缺陷不应超过6‰,以实现材料在系统中的正常使用。
  Secondly, the bond between the inner and outer layers of the thin steel flange ventilation pipeline and the internal insulation material is one of the basic conditions to ensure the composite material. Over a certain area of plate defects, not only affect the service life of the pipeline, sometimes also reduce its insulation effect. Therefore, the defect should not exceed 6, in order to achieve the normal use of materials in the system.
  目前,非金属管道材料发展迅速,品种较多。为保证使用安全,这些材料制成的风道应根据工程需要具有不燃或耐火B1级燃烧性能要求,其表层必须为不燃材料。根据我国多年的工程实践和产品现状,规定了热敏胶带和压敏胶带剥离强度试验的小值和铝箔厚度值。胶带的宽度应不小于50mm,防止使用胶带不能满足管壁密封强度和管道寿命。热粘带的优点是依靠热熔胶的粘合,只要不加热,粘带表面在室温下固化,粘接强度强。

  At present, non-metallic pipeline materials are developing rapidly and have many varieties. In order to ensure the safety of use, the ducts made of these materials should have non-combustible or refractory B1 level combustion performance requirements according to engineering requirements, and the surface must be non-combustible materials. According to the engineering practice and product status of our country for many years, the minimum peeling strength test value of thermal and pressure sensitive adhesive tapes and the thickness value of aluminum foil are defined. The width of the tape should be no less than 50 mm, so as to prevent the use of the tape from failing to meet the sealing strength of the pipe wall and the service life of the pipeline. The advantage of hot adhesive tape is that it depends on the bonding of hot melt adhesive. As long as it is not heated, the surface of adhesive tape solidifies at room temperature, and the bonding strength is strong.
  只有在风管加工过程中具备质量保证,风管才能发挥其作用,使客户在使用时能够达到预期的效果,真正满意风管的服务。
  Only in the process of duct processing with quality assurance, duct can play its role, so that customers can achieve the desired results in use, truly satisfied with the service of duct.
