After centuries of development, the production process of tinplate has been continuously improved under the trend of the times. The future direction and development trend of tinplate and high-speed electroplating tin industry need to be considered in the context of the times, that is, the development of high-speed tin plating must comply with the trend of resource conservation, energy conservation and environmental protection, and also need to be comprehensively considered in conjunction with production cost issues. The development trend of high-speed tin plating industry includes the following aspects.
Firstly, the production of low tin or even ultra-low tin tinplate. In recent years, tinplate has been increasingly threatened by low-cost materials such as aluminum, glass, plastic, etc. in the field of food packaging and canning. Meanwhile, due to the limited distribution of tin on Earth, resources are becoming increasingly scarce as usage continues to increase. To reduce costs and save resources, the continuous reduction of tin plating volume has become a major trend in the development of tinplate.
In addition, chromate passivation is widely used in the tin plating industry. Due to the high toxicity and carcinogenicity of chromate, as well as its serious environmental pollution, there are potential hazards in food safety. Therefore, environmentally friendly and low toxicity chromium free passivation technology is also an inevitable trend for the development of tinplate in the future.
