　　The processing of Jinan air duct is mainly composed of corner codes, clamps and connectors connected with the air duct as a whole. Although the cost of this kind of air duct is relatively low and the consumption of angle steel is reduced, its strength is not as good as that of angle steel in practical application, and the air leakage is also relatively large. It has to be machined. It is difficult to make by hand. It is usually only used for fresh air system, air conditioning system, etc. The smoke exhaust system is still an air pipe connected by angle steel. But the civil air defense project is absolutely not allowed to use the common board connection.

　　風(fēng)管制作過程中的材料要求相當(dāng)?shù)闹v究。當(dāng)風(fēng)管表面為鋁箔時，為了保證表面不容易損壞，指定了鋁箔材料和厚度，并指定了由鋁箔和增強(qiáng)材料組成的風(fēng)管表面的鋁箔厚度。

　　The material requirements in the air duct manufacturing process are quite exquisite. When the air duct surface is aluminum foil, in order to ensure that the surface is not easy to damage, the aluminum foil material and thickness are specified, and the aluminum foil thickness of the air duct surface composed of aluminum foil and reinforcement material is specified.

　　薄鋼板通風(fēng)管道內(nèi)外保溫材料的粘結(jié)是保證復(fù)合材料的基本條件之一。板在一定范圍內(nèi)的缺陷不僅會影響風(fēng)管的使用壽命，而且會降低風(fēng)管的保溫效果。因此，該缺陷必須不超過6，以實現(xiàn)材料在系統(tǒng)中的正常使用。

　　One of the basic conditions to ensure the composite material is the bonding of the internal and external insulation materials of the thin steel ventilation pipe. The defects of the plate in a certain range will not only affect the service life of the air duct, but also reduce the insulation effect of the air duct. Therefore, the defect must not exceed 6 to achieve the normal use of materials in the system.

　　非金屬風(fēng)管材料發(fā)展迅速，品種繁多。由于它們的特點和優(yōu)點，得到了越來越廣泛的應(yīng)用。為了保證使用的保證，根據(jù)工程需要，建議這些材料制成的風(fēng)管應(yīng)具有不燃或不燃B1的燃燒性能要求，表層必須是不燃材料。根據(jù)多年的工程實踐和我國產(chǎn)品的現(xiàn)狀，對熱壓帶的小剝離強(qiáng)度和鋁箔厚度的測試值進(jìn)行了規(guī)定。膠帶寬度要求不小于50mm，以防止膠帶不能滿足壁封強(qiáng)度和管道使用壽命。熱粘帶的優(yōu)點是它依賴于熱熔粘合。只要不加熱，膠粘劑的表面在室溫下固化，并具有很強(qiáng)的粘接強(qiáng)度。

　　Nonmetal air duct materials develop rapidly and have many kinds. Because of their characteristics and advantages, they have been more and more widely used. In order to ensure the use, according to the engineering needs, it is suggested that the air ducts made of these materials should have the combustion performance requirements of non combustible or non combustible B1, and the surface must be non combustible materials. According to the engineering practice for many years and the current situation of the products in China, the test values of the small peel strength and the thickness of the aluminum foil of the hot pressed strip are specified. The width of the tape shall not be less than 50mm to prevent the tape from failing to meet the wall sealing strength and the service life of the pipeline. The advantage of hot adhesive tape is that it depends on hot-melt bonding. As long as it is not heated, the surface of the adhesive solidifies at room temperature and has a strong bonding strength.

　　風(fēng)道加工是通風(fēng)空調(diào)系統(tǒng)的重要組成部分。它們大多由管道加工設(shè)備制成，如管道生產(chǎn)線。然而，由于各種原因，風(fēng)管處理設(shè)備處理的風(fēng)管可能會出現(xiàn)問題。

　　Air duct processing is an important part of ventilation and air conditioning system. Most of them are made by pipeline processing equipment, such as pipeline production line. However, for a variety of reasons, there may be problems with the ducts handled by the duct handling equipment.
