The weight of metal materials and products that cannot be used because of rust in the world is about 20% to 40% of the output of metal materials in the year. According to Hou Baorong, Academician of the Chinese Academy of Engineering, "China's corrosion status and control Strategy research" research group: "Our corrosion cost accounts for 3%-5% of GDP, and the corrosion loss in 2014 is about 2 trillion yuan or more", according to relevant statistics, the annual loss caused by rust corrosion is far greater than the sum of natural disasters and other types of accident losses.

Natural disasters in China (mainly flood, typhoon, drought and earthquake disasters, and including hail, cold freezing, snow disaster, collapse, landslide, debris flow, fire and forest fire and other disasters, according to the data of the statistics Bureau) : In 2014, all kinds of natural disasters caused a total of 337.38 billion yuan of direct economic losses across the country. In 2016, the total direct economic losses of natural disasters totaled 503.29 billion yuan, and in 2017, the total direct economic losses of natural disasters were 301.87 billion yuan.

It can be seen that the loss caused by rust corrosion is far greater than that of natural disasters in the same period.

According to our field investigation of a refrigeration equipment component production enterprise located in Hebei Province, the annual rework and scrap loss caused by rust accounted for about 35% of its output value. Improper selection of anti-rust oil agents and extensive protection process are important factors causing economic losses and high product costs. Therefore, the improvement of anti-rust protection quality of mechanical and electrical products needs to be paid attention to.

Teplunk has always put customer satisfaction in the first place, and after years of unremitting efforts, set up a strong R & D team, established a perfect quality control system, as well as a professional after-sales service team. It can provide reliable guarantee for the rust protection of mechanical processing and mechanical and electrical products.
