The so-called thermal spraying process (spray melt) refers to the use of some form of coating materials such as: metals, alloys, ceramics, metals, ceramics, plastics and composites, instantly heated to a molten state or plastic spray processing high prices, the formation of fog in the heat source After the heat source was shaped to a certain speed impact and deposited substrate surface to form a coating having a surface characteristic of thermal processing technology! With the development of industrial technology, a simple manual has been unable to meet the needs of the market, by manual spraying direction of development to industrial automation and increasingly high degree of automation, the application of coating production line has become increasingly widespread spraying processing hardware construction and deep into many areas of the national economy. Currently at the stage of learning and absorbing foreign technology, and the entire industry equipment belonging three products (no industry standards, no national standards, no market access). The main problem involves spraying equipment is designed to spray processing structure is irrational, not high tech. In our country especially after the reform and opening up has been spraying equipment has made considerable progress. In ancient China spray processing technology, people will be able to use natural dyes early on clothes, china, stained. It can be said spraying tool was using a brush, artificial. Fluorocarbon coating as a means of high-grade surface coating process, the quality of the whole process is extremely stringent requirements, in addition to the fluorocarbon coating manufacturer required to obtain permission to produce quality Kynar 500 PVDF paint as the base material, the paint manufacturer's entire surface treatment process, the curing process includes pre-treatment process, spraying process are subject to strict quality control to ensure the quality of the aluminum coating. Fluorocarbon coating industry in today's American Architectural Manufacturers Association standards to AAMA a 605.02.90 is mainly based on the spray standards, is recognized as a major international inspection coating quality standards. The following is a 605.02.90 AAMA standards of the major indicators of fluorocarbon coating. Spraying in AAMA standards, many references to the United States in South Florida as a test standard, because that is where the climate was humid, high temperature, direct sunlight is known, and therefore considered to be the coating quality inspection in harsh environments. Some of the world and the United States similar to AAMA-605.02.90 standard inspection standards, are also used to determine the fluorocarbon coating quality. They are: 1. British BS6496-1984 standard "building aluminum extrusions, sheet coating standard" 2. Germany GSBRAL-RC 631 1994 standard "quality aluminum construction inspection standards 3. Australia AS3715-1989 standard" metallic coating material standard "4. South Africa SABS a 1993" Architectural Outdoor aluminum coating standard "5 Switzerland" construction use Aluminum paint standard "1994 painting process | spray processing | Sand painting hung hardware appliances provided by the Dongguan City, Sha Hong Hardware Appliance Co., Ltd., Dongguan City, Sha Hong Hardware Appliance Co., Ltd.
