abstract
Steel and aluminum alloy materials are soaked or sprayed in a solution containing zinc phosphate, iron, manganese salt, etc. Due to the chemical reaction between metal and solution interface, water-insoluble zinc phosphate forms a protective film with a thickness of 0.5-5 microns on the surface of steel and aluminum alloy materials. This chemical interaction is called phosphating treatment of metal surface. Therefore, the phosphating treatment technology of metal surface came into being with a long history of hundreds of years. Because phosphating treatment is mainly composed of phosphate, nitrate, nickel salt, zinc salt, sodium nitrate, molybdate, fluoride, nitrite and other toxic and harmful heavy metal compounds, it is difficult to treat, and its wastewater discharge will also cause great pollution to the natural ecological environment, seriously endangering people's physical and mental health and destroying the ecological environment.
With the promulgation and implementation of "People's Republic of China (PRC) Environmental Protection Law", there are obviously more and more technical defects in the traditional phosphating treatment process, mainly reflected in the huge environmental pressure brought by industrial wastewater treatment. With the continuous development of industrial economy, the field of metal surface anti-corrosion materials treatment is gradually expanding, and the market demand for clean and environmentally friendly anti-corrosion materials is increasingly urgent. Therefore, in order to cooperate with the national overall economic construction transformation and upgrading plan, Yibo enterprises actively advocate "low-carbon energy-saving concept, casting environmental protection technology products" for the purpose, and collect more than 30 years of industry experience, constantly introduce modern enterprise management concepts, strengthen organization, and conduct in-depth research and development. Moreover, YBL-360 metal surface treatment agent, a low-carbon, energy-saving, economical and environmentally-friendly silane treatment agent, has been successfully developed through technical cooperation with advanced foreign countries, which can completely replace phosphating treatment. Its appearance has pushed the global metal surface anti-corrosion industry to a new milestone, initiated a new era of metal surface environmental protection anti-corrosion industry, and has been unanimously recognized and highly praised by customers in more than ten years of market application. At present, successful cooperation cases include: Ningbo Huarui Metal Products Co., Ltd., Shandong Longji Machinery Co., Ltd., Ningbo Shenma Children's Products Co., Ltd., Anhui Sanle Baby Products Co., Ltd., etc. At the same time, he is also a member of China Environmental Protection Industry Association, an excellent demonstration unit of Zhejiang Industry Alliance, a partner of Yin Da Engineering Enterprise Brand Public Welfare Exhibition, and a special guest of new power entrepreneurs. CCTV Agricultural Channel of CCTV also made a lot of special publicity and interviews, and the products passed the appraisal of national anti-corrosion performance, adhesion performance, chemical hazard performance, highway (aviation) transportation conditions, SGS EU standards, SVHC-2 1 1 EU standards, and obtained the national intellectual property invention patent, patent number: ZL2015655.
