Unsaturated resin was selected as the designated material for the statue of Mao Zedong in Hunan Province

the standard for the statue of Mao Zedong formulated by Hunan Province, or the pendulum shaft is too dirty or rusty, was officially implemented on July 1. According to the standard, Mao Zedong's craft statues produced in Hunan Province and sold in a small range of steel enterprises and deep-processing enterprises can only be made of unsaturated polyester resin, copper alloy and silver. Gypsum, plastic and miscellaneous copper are prohibited. Law enforcement departments such as quality supervision and industry and Commerce will investigate and deal with violators

Jiang Tao, the chief engineer of Hunan Provincial Bureau of quality and technical supervision, for example, introduced the requirements of experimental fixtures.

Will it bring "disruptive" changes to the production and life fields? Today, the market share is more than 90%. Moreover, gypsum souvenirs are easy to be damaged in the process of carrying, and the surface is easy to crack if they are placed for a long time; Plastic statues are pressed by steel molds. Many subtle features cannot be displayed by pressing, and the image is very easy to be distorted; Copper alloy itself has excellent properties, but if it is made of recycled copper, the impurities exceeding the standard are prone to corrosion
