Composition and role 1) K-301 etching agent: K-301 by the etching agent degreasing agents, strong oxidizing agents, ligands, cationic surface active agents, corrosion inhibitors, brighteners components. (2) degreasing agent [3] compared the advantages and disadvantages of both basic and acidic degreasing processes Dongguan aluminum products processing, acid degreasing the substrate surface smooth and bright, no passivation film processing, active center uniform. Practice has proved that 4-axis machining, degreasing acid degreasing processes (oil) thoroughly, and avoid alkali mist contamination, fouling. The new standard degreasing process is: the self-timer lever workpiece degreasing of aluminum parts processing, the entire surface can be wet with water (i.e., 100% oil). In H2SO4 (20% -30%) was added to a surfactant having wetting, emulsification, solubilization and so on, and to promote the film from metal surfaces emulsification reaction, the film quickly broken down into small oil droplets from the metal surface , revealed a clean metal substrate. Industrial clusters leading industry clearly improve the degree of specialization, the formation of a regional advantage. Average total industrial production of various industrial clusters leading industry more than 10 billion yuan, and its main products in the same industry are in a leading position. Each industrial base has exceeded the total profits of 10.6 billion yuan, have become one of the main pillars of the local industrial economy. Each cluster high degree of specialization, the production technology is more mature, more perfect management, marketing, supply and marketing network is perfect. Brand stronger, more comprehensive supporting industries. Each cluster attaches great importance to the construction of public service platform, supporting the formation of a transformation and upgrading. In the local government's strong support of the construction product research and development center, testing center, training center, information center, logistics center and trade centers have achieved gratifying results, and promote the industry, academia, research, trade, the prosecution of cooperation and communication, but also promoted the independent innovation boom. In doing this the more prominent is the Siu Lam, Shunde, Jieyang, Zhongshan, Anping, danzao other places. 5-axis | Hong Run (certified) | processed by Hongrun Dongguan Shijie Hardware Products Factory.
