通風管道廠家對于風管制作過程中對材料的要求是相當有考究的，風管表面層為鋁箔材質時，為確保表面層不易損壞，故對鋁箔材質及厚度作出規定，并對鋁箔與增強材料復合的風管表層的鋁箔厚度作了規定。
Ventilation pipe manufacturers are quite sophisticated for the material requirements of the wind pipe production process, the wind pipe surface layer is an aluminum foil material, to ensure that the surface layer is not easy to damage, so the provisions of foil material and thickness, and the thickness of the aluminum foil and aluminum foil reinforced composite wind pipe surface has been specified.
其次，薄鋼板法蘭通風管道內、外表層和內部絕熱材料粘接牢固，是保證復合材料的基本條件之一。超出一定面積的板材缺陷，不僅影響風管使用壽命，而且有時會降低其保溫效果。所以缺陷不得大于6‰，以達到材料在系統中的正常使用。
Secondly, the inner layer, the outer layer and the internal thermal insulation material of the steel flanges are firmly bonded, which is one of the basic conditions of the composite material. Beyond a certain area of the plate defects, not only affect the service life of the wind pipe, and sometimes reduce its insulation effect. Therefore, the defect shall not be greater than 6 per thousand, in order to achieve the normal use of materials in the system.
目前，非金屬風管材料發展較快，品種較多，困其具有的特性和優點，應用也越來越廣泛。為了保證使用中的，對這些材料制作的風管提出了應按工程的需要具有不燃或難燃B1級的燃燒性能要求，而其表面層必須為不燃材料。
At present, the development of non metallic wind pipe material is faster, more varieties, and its characteristics and advantages, the application is more and more widely. In order to ensure the safety of the use of these materials produced by the wind pipe should be in accordance with the needs of the project is not flammable or difficult to burn B1 level of combustion performance requirements, and its surface layer must be non combustible material.
根據我國多年的工程應用實踐與產品狀況，規定了熱敏膠帶與壓敏膠帶的剝離強度試驗較低值與鋁箔厚度值;要求膠帶寬度不應小于50mm，防止使用的膠帶不能滿足管壁密封的強度和風管使用年限。熱敏膠帶的優點是依靠熱熔粘接，只要不在加熱，在常溫下膠面是固化的，具有牢靠的粘接強度。
According to the engineering practice and product status in China for many years, the provisions of the minimum value of the peel strength test of thermal tape and adhesive tape and foil thickness requirements; the tape width should not be less than 50mm, to prevent the tape can not be used to meet the sealing wall strength and wind period of use. The advantage of heat sensitive adhesive tape is to rely on hot melt adhesive, as long as it is not heated, it is solidified at normal temperature.
