Difficult to clean because of a halogen ion, the residue of high ion, a halogen element (mainly chloride) has strong corrosive, it is not suitable for use as raw material for clean flux, halogen-free outer active agent, slightly weak activity but less ionic residues. The appearance of the active agent is mainly a non-ionic surfactant look aliphatic or aromatic fatty acid flux Which is better, whose main function is to reduce the appearance of tension generated when the solder metal between the lead foot touches the flux role in enhancing the appearance of lip Wet force. Henan environmental flux: isopropanol heavier taste some alcohol there is alcohol flavor flux, although suppliers may also use a mixed solvent, but require suppliers to provide components of the speech, he will provide general but isopropanol price is about 3-4 times the methanol and suppliers lower prices if severe, may be there's something not easy to say. OK sample which many manufacturers choose the most fundamental method of flux. . _ FUJIE solder flux component (certification) _ Kaifeng flux provided by the Zhengzhou City Fujie Soldering Materials Co., Ltd. Zhengzhou City Fujie Soldering Materials Co., Ltd. (www.fujiehanxi.com) (www.fujiehanxi.com) is Zhengzhou, electronics, electrical products processing leader, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness , the maximum meet customer needs. In FUJIE solder leadership with the staff warmly welcome all inquiries negotiations to create FUJIE solder a better future.
