Heze Acetylene tape Also called pu steel wire pipe, ventilation pipe, dust removal pipe, dust collection pipe, dust conveying pipe, industrial powder dust collection pipe, sweeping car dust collection pipe, drilling machine dust collection pipe, woodworking dust collection pipe, collectively called dust collection pipe. Therefore, industrial food dust transportation and industrial dust transportation are used for dust collection pipe. The production process structure of copper plated steel wire dust collection pipe is to wrap the pipe wall with solid elastic copper plated steel wire spirally, and the pipe wall material is coated with copper plated steel wire with special polyether PUR. PUR material is also called PU material. The thickness of pipe wall can be 0.4mm, 0.6mm, 0.9mm, 1.2mm, 1.5mm, 1.8mm and 2.1mm, depending on the customer's needs. Such as the temperature, wear resistance, flexibility and bending, hydrolysis resistance of the dust collection pipe. It is also necessary to consider whether static electricity is generated in the process of pipe full conveying dust to avoid unnecessary dust explosion and fire. Copper plated steel wire plastic coated dust collection tube is suitable for vacuum pumping of powder and particle in industrial and mining, agriculture, water conservancy, civil engineering, food, petroleum, chemical industry, health and other industries, and transporting water, oil, chemical materials, food, etc. Abrasive solids such as dust, powder, fiber, chip and particle, gas and liquid environment, for dedusting and suction plant, Acetylene tape company Industrial vacuum cleaners, paper and textile fibers, are used as protective tubes. It is widely used in farmland irrigation, industry and mining, oil depot, sand extraction, sand blasting, food, medicine, indoor gas, powder, dust absorption and emission and other fields. This product is a substitute for PVC, rubber and metal pipes.
The spiral air duct will certainly be affected in the low temperature environment, so how should our manufacturer deal with this situation? First Acetylene tape company Do a good job in thermal insulation and select thermal insulation materials (applicable to industry and construction industry), but the selection of thermal insulation materials (applicable to industry and construction industry) is also necessary. Shandong Hongyuansheng, a spiral air duct manufacturer, will tell you how to choose. Good thermal insulation performance. The specification of the next thermal insulation material (applicable to industry and buildings) should meet the requirements of the air duct system used, not only that, but also the design requirements of the air duct. The thermal insulation material (applicable to industry and buildings) has product quality certificates and other qualified documents. Galvanized spiral air duct is widely circulated in the municipal spiral air duct market. The galvanized steel plate spiral air duct is basically the feature of stainless steel spiral air duct, but its price is only two thirds or even lower than that of stainless steel air duct. Composite spiral air duct is generally used in the environment where the environment is common, and the requirements for air duct are not too high. Thermal insulation materials (used in industry and construction) can effectively protect pipelines from damage in winter. Galvanized spiral air duct is widely circulated in the spiral air duct market. The galvanized steel plate spiral air duct is basically the feature of stainless steel spiral air duct, but its price is only two thirds or even lower than that of stainless steel air duct. Heze Acetylene tape It is generally used in the environment where the environment is common, and the requirements for air ducts are not too high. In terms of clean air ducts, fire-resistant closed cell rubber foam insulation materials (used in industry and buildings) are generally used, and incombustible aluminum (aluminum) foil glass wool board is used for smoke exhaust ducts. These two materials are common and have good thermal insulation performance.
The so-called acid and alkali resistant rubber hose is the rubber hose used to transport acid and alkali solutions, which can be divided into wear-resisting Acetylene tape , acid and alkali resistant cloth clip hose, etc; In actual production, using a certain proportion of recycled rubber for acid and alkali resistant rubber hose can not only reduce the cost of raw materials, but also improve the aging resistance of rubber compound, thus extending the service performance and service life of acid and alkali resistant rubber hose. However, if you want to significantly improve the aging resistance of acid and alkali resistant hose, it is impossible to rely solely on recycled rubber, and rubber antioxidant is essential. What anti-aging can be used in acid and alkali resistant hose? 1. Antioxidant A: Antioxidant A, namely, antioxidant A, is in the form of yellowish brown to purple crystal blocks at room temperature. It is a universal antioxidant, which has good resistance to heat, oxygen, flexion, weather and fatigue aging. It also has a certain inhibitory effect on harmful metals. It is easy to disperse in the rubber compound, and has no obvious impact on the processing performance of the rubber compound and the physical and mechanical strength of the vulcanizate, It is the preferred antioxidant product in the production of acid and alkali resistant hose. It can also be used as a stabilizer in the acid and alkali resistant hose containing styrene butadiene rubber, which can significantly delay the aging time of acid and alkali resistant hose. 2. Antioxidant D: antioxidant D, namely N-phenyl - β－ Naphthylamine (D) is a kind of heat aging resistance commonly used in the production of rubber products, Acetylene tape company Anti aging agent resistant to fatigue aging; Due to the poor heat resistance of the acid and alkali resistant hose, the use of a small amount of antioxidant D in the protection system can improve the heat aging resistance of the rubber compound, thereby improving the heat resistance of the acid and alkali resistant hose, expanding the use temperature range, and extending the use time.

Air duct mainly refers to the ventilation duct of the central air-conditioning system, which is often ignored, but it is an important part of the air-conditioning system. Heze Acetylene tape What are the regulations for welding air ducts? Gongfa HVAC is a manufacturer dedicated to the production of air ducts, which has been recognized and supported by the majority of users for many years. 1、 The welding regulations of carbon steel plate air duct are as follows: 1. The carbon steel plate air duct should be welded by DC welder. Introduction to welding air duct If AC welding machine is used for welding, a vibrator must be added to reduce excitation and stabilize the arc. When welding steel plates, the arc is unstable, which can lead to deterioration of weld quality. 2. Before welding, remove the dirt, oil stain and rust at the welding port; When spot welding or continuous welding is used, the oxide shall also be removed. The butt joint shall be kept with the minimum gap, and the overlap at the manual spot welding location shall be removed in time. After welding, the electrode slag and residual welding wire in the weld and its surrounding area shall be removed in time. 2、 The welding regulations of stainless steel air duct are as follows: 1. Before welding the air duct, remove the grease and dirt in the weld area to prevent pores and sand holes in the weld. Cleaning can be carried out with gasoline, acetone, etc. When welding stainless steel plates by electric arc welding, the surfaces on both sides of the weld should be coated with white ash, Heze Acetylene tape To avoid welding slag splashes adhering to the surface of the plate. 2. After welding, attention shall be paid to removing the slag at the weld, brushing the metal luster with a copper wire brush, pickling with 10% nitric acid solution, and then cleaning with hot water.
