SM材料是用于制作大型三向渗流模型的地形,浸润面的材料.由硬脂酸、石蜡、滑石粉等按一定比例、一定的工艺步骤配合而成.它与过去使用的以沥青为主的模型材料相比具有以下主要优点:1、不存在环境污染问题;2、熬制浇注的温度比沥青模料低60℃以上,操作安全;3、SM材料在65℃左右流动性仍旧很好,便于浇注大而复杂的模型;4、更容易修刮,且具有必需的强度;5、污迹易清除.已正式投入使用.
SM material is used to make large-scale three-dimensional seepage model terrain, infiltration surface material. Stearic acid, paraffin wax, talcum powder, etc. in a certain proportion, a certain process steps are combined. It is mainly used with asphalt in the past The model material has the following main advantages compared to the following: 1. There is no environmental pollution problem; 2. The temperature of tanning and casting is lower than the temperature of the asphalt mold material by more than 60°C, and the operation safety; 3. The material mobility of SM material is still good at about 65°C. ,Easy to cast large and complex models; 4, easier to scratch, and has the necessary strength; 5, stains easy to remove. Has been officially put into use.
