In the coated sand production areas should be strengthened following two aspects: (1) hair coated sand coated sand cleaner renewable manufacturers, mainly from the following aspects: ① to reduce the amount of resin and curing temperature; ② improve coated sand overall performance of coated sand recycling equipment companies, especially high temperature performance; study pollution phenolic resin substitutes ③ strengthened;. (2) increase the regenerative capacity of coated sand coated sand coated sand production equipment package recycling has been a topic of concern for the majority of experts, the current coated sand regeneration equipment is expensive and regeneration efficiency is not high, productivity is 5 tons / hour The thermal regeneration equipment prices in the 1200-1600 yuan, coated sand regeneration cost 65-90 yuan / ton, this is where the cost can not be coated sand casting production areas of domestic enterprises should strengthen the following two aspects: (1) made of coated sand pollution, mainly from the following aspects: ① to reduce the amount of resin and curing temperature; ② coated sand to improve the overall performance, especially in high temperature performance; ③ strengthen phenolic resin polluting alternatives the study;.
