2 / extrusion temperature and extrusion speed of the rod is conducive to high temperature diffusion bonding of metal, metal bonded but exacerbate the phenomenon of mold, while the high temperature insulation dedicated board, in turn results in the metal grain growth and tissue grow faster, and thus enable weld thick. Jinan dedicated high speed extrusion insulation board price increases of metal deformation work, metal temperature is large. In addition, high temperature extrusion, extrusion pressure will be reduced, thus also reducing the welding force. Therefore, the production site, the most practical is to lower the temperature in Jinan rod special insulation board manufacturers, and then before the molds and other analysis or repair weld cleaning: aluminum and aluminum alloy welding, should be strictly removed before welding workpieces weld and the oxide film and the wire surface oil; 1) chemical cleaning chemical cleaning high efficiency, stable quality, and size is not suitable for cleaning up the wire, mass production of the workpiece. Available in two French immersion method and scrub. Available surface organic solvents acetone, gasoline, kerosene, etc. to oil, with a 5% ~ 10% NaOH solution caustic 40 ℃ ~ 70 ℃ for 3 min ~ 7 min (aluminum a little longer, but not more than 20 min), mobile water rinse Shandong special insulation board supplier, followed by room temperature to 60 ℃ of 30% HNO3 acid solution 1 min ~ 3 min, mobile wash, air dry or low temperature drying. Jinan special insulation panels, rolls Aluminum (certified), insulation is provided by a dedicated board Aluminum Co., Ltd. Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) Shandong Jinan, aluminum products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Aluminum leadership in cis with the staff warmly welcome all inquiries negotiations to create a better future for aluminum rolls.
