中文摘要:
      传统的蜡处理工艺采用静置沉降法,蜡料在使用中经常出现蜡件凹陷、流纹多、气泡明显,以及修蜡时粘刀、蜡屑很难清洗等问题,严重影响了产品质量。为了解决这些问题,采用162型中温蜡料生产铸件,探究蜡料中水含量对蜡料综合性能和成型质量的影响。研究发现:随着水含量的上升,蜡表面质量趋于变好,蜡件比较饱满;当蜡料水含量控制在4%~7%时,蜡件的线收缩、凹陷及表面流纹较轻,综合使用性能好,且修蜡不粘刀,蜡屑容易清洗。因此,生产中可通过制作标准对比块,采用观察颜色的方法严格控制并监测蜡料中的水含量。此法简单、方便、可行,可用于蜡料生产中水含量的监测。
英文摘要:
      The traditional process of wax processing adopts static settling method, and wax material often occurs with a concave, flow lines, apparent bubbles, and the difficulty in cleaning the pasted knife and wax crumbs during trimming of the wax, which seriously affects the quality of the product. In order to solve these problems, the effect of moisture content on the synthetic properties of waxes and the forming quality of wax materials are studied by using the 162 medium-temperature wax. The result shows that as the water content increases, the surface quality of the wax tends to increase and the wax is full. When wax material moisture content is controlled between 4%~7%, wax line contraction, sag and surface flow lines are not so apparent, the comprehensive usability is good, wax doesn't stick on the knife during trimming of the wax, and wax crumbs are easy to clean. The results show that the water content of the wax can be controlled and monitored by the method of observing color through making standard sample for comparison. This method is simple, convenient and feasible, and can be used in the monitoring of moisture content in wax production.
