Powder coatings are a cost effective and an environmentally friendly alternative to liquid coatings. Traditional coating systems form networks via a thermally activated process.This usually involves placing a powder coated surface into an oven at temperatures between 160°C and 200°C. The powder melts at around 80°C to 120°C and becomes an even film. At temperatures between 110°C and 140°C the cross linking reaction starts. The curing time typically lasts between 15 and 30 minutes, depending on the temperature and reactivity of the system.

哈克压力控制流变仪在橡胶方面的应用（English）

简介：1. Introduction and objectives A great variety of rubber parts is produced for the automotive industry. To minimize problems during the ssembly of the cars and to ensure best performance, the parts have to be manufactured with the smallest possible variation in size and shape. The size can be controlled by the extrusion and injection parameters – the shrinking of the material can often be well estimated.
红外光谱法定量分析轧制油中的醇，酯添加剂含量-210-280--MO0104

简介：轧制油是铝板、带、箔生产中重要的辅助材料，它直接影响到工艺的运行及最终产品的质量。轧制油的添加剂主要由醇、酯等组成，红外光谱分析中二者的特征吸收峰互不干扰，也不受背景（基础油）影响。根据朗伯-比尔定律可以得到各组分浓度与吸光度的工作曲线，从而准确地求出添加剂中各组分的浓度。本文实验中选用Specac公司提供的500um Pearl液体透射附件，不仅简化了实验操作，而且准确测试出待测样品的浓度。
