Other special requirements for coated sand to meet the needs of different products, developed a series of special coated sand as: centrifugal casting coated sand, chilling coated sand, wet coated sand, sand sticking, anti-veined, Anti-cellulite coated sand. While in 2004 the newly introduced fast-curing coated sand on the basis of the performance has the cure rate can increase 30-70%, improve production efficiency coated sand regeneration, and energy saving easy collapsibility coated sand has a better class strength, but also has excellent low temperature performance of coated sand collapsing renewable suppliers, for the production of non-ferrous castings. Adhesive coated sand on the quality of the performance has a great influence coated sand regeneration plant, people have been working on how to improve the performance of phenolic resin coated sand recycling plant, as well as to find alternatives phenolic resin. Abroad has developed a special resin with different properties, such as high strength, low gas resin, the resin is easy to collapsing, there are reports of the use of modified polyester resin, but did not get the full extension, so far is still widely used modified phenolic resin. In recent years, the rapid development of the country in terms of research and development of special phenolic resin coated sand, has developed a different use for the production of modified phenolic resin coated sand recycling equipment | coated sand regeneration | Qingdao Qingdao Heng Heng Machinery Co.
