Zhejiang Zhongfa Film Co., Ltd. is located in Zhejiang Industrial Development Zone, Shaoxing City, Zhejiang Province, covering an area of ​​200 mu. The first phase investment is 210 million yuan. The complete ABC three-layer coextrusion biaxial stretching production line and testing equipment are imported from Bruckner, Germany. It is the latest design configuration of Brückner. Its special equipment configuration reflects the most advanced of the world's two-way stretch polyester film equipment. Horizontal, outstanding features: The product has exceptional thickness uniformity and extremely low heat shrinkage rate, making it more suitable for the production of special functional films. From the feeding to the finished products, Siemens electrical control system is adopted to realize automatic computer automatic monitoring. The production speed is fast, the product grade is high, the quality is stable, and the comprehensive performance is excellent. It is suitable for the production of multi-variety, multi-purpose and high-tech application fields. Thickness range: 8~75um, with an annual production capacity of 15,000 tons.
At present, the company's products have been sold throughout the country, and some exports. The company has first-class technical experts and excellent management team, and is constantly developing new varieties. It has developed a variety of new varieties such as high brightness, super bright, high temperature resistance, retort resistance, high strength and low shrinkage. The market is well received by users.
The finned tube is to improve the heat exchange efficiency. By adding fins on the surface of the heat exchange tube, the outer surface area (or inner surface area) of the heat exchange tube is increased, so as to achieve the purpose of improving the heat exchange efficiency. Such a heat exchange tube . Usually used for heat exchange between liquid and gas.
Finned tube is a heat exchange element. As a heat exchange element, finned tubes usually work under high-temperature flue gas conditions for a long time. For example, the finned tubes usually used in boiler or harsh environments, high temperature and high pressure, and in a corrosive atmosphere. This requires that the finned tubes should have high anti-corrosion properties, Anti-wear properties, lower contact resistance, higher Stability and anti-dusting ability.
There are many types of finned tubes, and new varieties are constantly emerging. According to the classification of processing technology, there are extruded fin tube; high frequency welded finned tubes; rolled formed finned tubes; suit formed finned tubes ; cast finned tubes; tension wound finned tubes; Inserted tubes.
According to the shape of the fins, there are square finned tubes; circular finned tubes; spiral finned tubes; longitudinal finned tubes; corrugated finned tubes; spiral serrated fins Helical Serrated Finned Tubes; pin-shaped finned tubes; integral plate-shaped finned tubes; inner finned tubes.
According to whether the fin material of the finned tube is the same as that of the base tube, it can be divided into: single metal finned tube, bimetallic composite finned tube.
Single metal finned tubes are classified by material into copper finned tubes; aluminum finned tubes; carbon steel finned tubes; stainless steel finned tubes; cast steel finned tubes.
