Alkaline phenolic resin sand application

The strength of alkaline phenolic resin self-hardening sand increases with the increase of resin content, but its strength increases slowly to a certain amount. The increase of resin dosage will not only increase the production cost, but also increase the residual alkali in the resin sand and the carbonaceous coating layer on the surface of the sand, which will affect the quality and strength of the recycled sand and the regeneration rate of the old sand.

Mianchi Chenghui New Materials Co., Ltd., with an annual output of 40000 tons of molten ceramic sand (Baozhu Second Sand), is located in Yingzhang Industrial Park, an industrial agglomeration area in Mianchi County, Henan Province, with a total investment of 0.15 billion yuan and an area of 65 mu. The first phase, with an investment of 60 million yuan and an area of 20 mu, is designed to produce 15000 tons of molten ceramic sand (Baozhu sand) annually and will be put into production in May 2019. This project is based on the rich and high-quality bauxite raw materials in Mianchi, supported by the strong scientific and technological advantages of Southeast University, and relying on the convenient environmental advantages of Mianchi industrial agglomeration area, to build a domestic molten ceramic sand production base as the goal, to promote the transformation and upgrading of the domestic casting industry as the concept, to build Mianchi molten ceramic sand (Baozhu sand) and green casting industrial park, for the development of China molten ceramic sand (Baozhu sand) to a higher level, lay the foundation.
