The benefits of improved chrome-free passivating agents

Chromium-free passivation agent, is a new environmentally friendly products in recent years, is following the trivalent chromium passivation agent has a more environmentally friendly technology in the product, it can be said in the environmental protection is already perfect.

However, when environmental protection is perfect, we found that the effect of chromium-free passivation and process relative to the trivalent chromium passivation agent is greatly different.

For such a market short board, the company also early discovery, with the development of society, especially this year's "APEC blue" this new vocabulary, and the moral word

In the provinces and cities around Beijing, the environmental protection is unprecedented, whether it is the vehicle limit, or factory sewage, smoke emissions, especially the chemical industry, the requirements are very high, especially the proposed use of chemical products, must Is completely environmentally friendly, which means that trivalent chromium passivation agent in the industry as environmentally friendly products in the Beijing border area is also can not be used, so these manufacturers will respond to national policies, the use of completely environmentally friendly chromium-free passivation Agent, instead of the traditional trivalent chromium passivation agent, but also a blue sky.

At this time, these manufacturers, in the replacement of passivation agent when the liquid found that the current chromium-free passivation agent on the market, not easy to use, especially in the salt spray requirements, simply can not achieve the desired results.

For this problem, the company as early as a few years ago to deal with environmental protection strategy, the chromium-free passivation of such environmentally friendly products such as a strong research and development improvements, has been on the chromium-free passivation of salt mist short board, made Significantly improved, has exceeded the international standards, in terms of environmental protection is also fully meet the requirements.

The following is the introduction of chromium-free passivation: chromium-free passivation agent is used for aluminum, aluminum alloy, zinc alloy chrome-free surface passivation agent, which is my company in response to environmental protection is increasingly high and research and development of outstanding products; Products in full compliance with the European ROSH standards; chromium passivation agent generated by the passive layer has a very strong stability, greatly improving the material and coating film adhesion and corrosion resistance, and its excellent corrosion resistance in the industry similar products In the top, bare aluminum neutral salt spray up to 120 hours, the natural conditions of the bare film for more than 5 years without oxidation, painted salt spray up to 1200-1500 hours; film color is golden yellow and colorless two, Available for customers.
