        白鐵風管對材料有哪些要求?

        來源:http://www.boursomarket.com 日期:2019-07-09 發布人:admin

          風管在生產過程中對材料的要求是相當講究的。當風道的表層是由鋁箔,為了確保表層不容易損壞,鋁箔規定的材料和厚度,鋁箔的厚度和表面增強材料復合風道規定。
          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,薄鋼法蘭通風管道內外面層與內部保溫材料粘結牢固是保證復合材料的基本條件之一。超過一定面積的板缺陷,不僅影響管道的使用壽命,有時還會降低其保溫效果。因此,該缺陷不應超過6‰,以實現材料在系統中的正常使用。
          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,非金屬管道材料發展迅速,品種較多。為保證使用安全,這些材料制成的風道應根據工程需要具有不燃或耐火B1級燃燒性能要求,其表層必須為不燃材料。根據我國多年的工程實踐和產品現狀,規定了熱敏膠帶和壓敏膠帶剝離強度試驗的小值和鋁箔厚度值。膠帶的寬度應不小于50mm,防止使用膠帶不能滿足管壁密封強度和管道壽命。熱粘帶的優點是依靠熱熔膠的粘合,只要不加熱,粘帶表面在室溫下固化,粘接強度強。

          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.
          只有在風管加工過程中具備質量保證,風管才能發揮其作用,使客戶在使用時能夠達到預期的效果,真正滿意風管的服務。
          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.
