在铸造生产过程中,为了保证铸铁件表面质量,防止铸件粘砂,往往在铸型上涂刷涂料。千百年来,我们的祖先均以石墨粉作为铸铁涂料的基料(耐火材料)。但是黑色石墨是造成环境污染,使人感受坏的重要因素。为了改善铸造工人的劳动环境,我们试制成功了白色涂料。 In the casting production process, in order to ensure the surface quality of cast iron parts, to prevent the casting sticky sand, often painted brush coating on the mold. For thousands of years, our ancestors used graphite powder as the base material for cast iron coatings (refractory materials). However, black graphite is an important factor that causes environmental pollution and makes people feel bad. In order to improve the working environment of the foundry workers, we successfully produced white paint.
