项目摘要
The objective of this proposal is to purchase a two-roll mill for the development of rubber/elastomer formulations. The equipment will be used to study samples based on blends, (nano)composites, hybrids systems, etc. However, the team will focus on biobased materials (resins, reinforcements and additives) due to the high demand from companies asking help on production problem solving (troubleshooting), raw materials (selection and formulation) and complete characterizations (raw materials and final parts). Biobased materials are more sensitive than petroleum-based materials to degradation via mechanical stresses (shear/elongation) and high temperature mixing conditions due to their functional groups (hydroxyl, amine, etc.). Thus, excellent mixing quality at low speed and low temperature must be performed to limit degradation associated with the processing steps. This is also the case for foams using chemical blowing agents having decomposition temperatures close to the material's processing temperature. Therefore, a good temperature control (value and distribution) is essential to limit thermal decomposition in the mixing step and keep their full blowing efficiency in the production (molding) step. This why a lab-scale two-roll mill is necessary since the equipment can be run at low speed. Moreover, the distance between the rolls to control the shear/elongation rates imposed on the formulations can be easily controlled. It is also easy to control the final mixing quality by the number of cycles the materials go through. Finally, the temperature distribution can be highly uniform and kept low since the materials' thickness is small and the rolls (cooled with a high-power chiller) have high surface area. The equipment selected includes hardened steel rolls and precise manual roll distance adjustment. A high power/torque motor for highly viscous (highly filled) materials/compounds is combined with an AC variable speed option (variable speed drive motors) for a wide range of roll speed. To the best of our knowledge, no such equipment is available in an academic institution (college or university) in Canada to provide support for the Canadian rubber industries. Furthermore, this industry is faced with two major problems: qualified personal availability and waste rubber management. This proposal will address both issues by training students on a very specialized processing equipment and by introducing them to sustainable development concepts by investigating recycled/biobased materials.
本提案的目的是购买一台双辊磨机,用于橡胶/弹性体配方的开发。该设备将用于研究基于共混物、(纳米)复合材料、混合系统等的样品。然而,该团队将专注于生物基材料(树脂、增强材料和添加剂),因为公司对生产问题解决(故障排除)、原材料(选择和配方)和完整表征(原材料和最终部件)的帮助需求很高。生物基材料比石油基材料更容易因其官能团(羟基、胺等)而在机械应力(剪切/伸长)和高温混合条件下降解。因此,必须在低速和低温下进行优异的混合质量,以限制与加工步骤相关的降解。对于使用分解温度接近材料加工温度的化学发泡剂的泡沫也是如此。因此,良好的温度控制(值和分布)对于限制混合步骤中的热分解并在生产(成型)步骤中保持其完全吹塑效率至关重要。这就是为什么实验室规模的双辊磨机是必要的,因为设备可以在低速下运行。此外,可以容易地控制辊之间的距离以控制施加在制剂上的剪切/伸长速率。通过物料经过的循环次数也可以轻松控制最终混合质量。最后,由于材料的厚度小,并且辊(用高功率冷却器冷却)具有高表面积,因此温度分布可以高度均匀并保持较低。所选设备包括淬火钢辊和精确的手动辊距调节。适用于高粘度(高填充)材料/化合物的高功率/扭矩电机与交流变速选项(变速驱动电机)相结合,可实现宽范围的辊速。据我们所知,在加拿大的学术机构(学院或大学)中没有此类设备可以为加拿大橡胶工业提供支持。此外,该行业还面临着两个主要问题:合格人员的可用性和废橡胶管理。该提案将通过培训学生使用非常专业的加工设备和通过调查回收/生物基材料向他们介绍可持续发展概念来解决这两个问题。
