随着合成材料工业的迅速发展,在机器设备中亦采用了塑料零件。塑料喷涂是塑料成型工艺中较新的一种方法,它是在金属基体上涂复一层薄塑料,而其强度、刚性仍由基体保证,这样能发挥喷料的优越性,降低制造成本,改善塑料耐热性低和导热差的弱点。我厂设备动力科经过一年多的试验研究,已把塑料喷涂技术运用在机械零件的磨损修复和作零件的防腐蚀涂层,使用至今效果良好,具有缩短停修周期、降低修理成本和节约大量金属材料等优点。现将情况简介于下。一、塑料喷涂的实质和设备塑料喷涂是用压缩空气或惰性气体,将塑料粉末
With the rapid development of synthetic materials industry, plastic parts are also used in machinery and equipment. Plastic spraying is a newer method of plastic molding process, which is coated with a thin layer of plastic on the metal substrate, while its strength, rigidity is still guaranteed by the substrate, which can play the advantages of spray, reduce manufacturing costs, Improve the plastic heat resistance and thermal conductivity of weaknesses. After more than a year of experimental research, we have applied the plastic spraying technology to the wear repair of mechanical parts and the anticorrosive coating of parts, which has been used well so far, with the advantages of shortening the period of maintenance, reducing the repair cost and saving A large number of metal materials and other advantages. The situation is now below. First, the essence of plastic spraying and equipment Plastic spraying is the use of compressed air or inert gas, the plastic powder
