由浙江省嘉兴市机械研究所研制的SMT-1铸造涂料密度计于1987年12年24月在嘉兴市通过市级技术鉴定。这种涂料密度计应用流变学原理,根据涂料密度的定义研制而成;设计新颖,结构简单、合理,测试方便、迅速,且不需使用天平。它既能测定铸造涂料的密度(习惯称“比重”),又能测定涂料的悬浮稳定性,还可用于测定铸造及其它行业各种液状流体的密度。该仪器为国内首创,填补了我国铸造测试仪器的一项空白。 By the Jiaxing City, Zhejiang Institute of Machinery developed SMT-1 casting paint density meter in December 1987 in December 24 in Jiaxing City through municipal-level technical appraisal. This kind of coating density meter is based on the rheological principle and is based on the definition of coating density. The design is novel, the structure is simple and reasonable, the testing is convenient and rapid, and the balance is not needed. It measures the density of foundry coatings (conventionally called “specific gravity”), as well as the suspension stability of coatings, as well as the density of various liquid fluids found in foundries and other industries. The instrument for the domestic initiative, to fill our country casting test equipment a blank.
