An innovative CO₂ utilization approach for skim rubber production was developed in this research. Traditionally, skim rubber is produced using a substantial amount of concentrated sulfuric acid to coagulate the rubber particles. Before acid addition, ammonia removal process is required to reduce the volume of acid used. This process, however, involves large operating area, long processing time, environmental issues, and health hazards. To minimize those drawbacks, as a process intensification technique in this study, CO₂ microbubbles were applied as a feedstock to reduce the ammonia and hence the volume of acid addition. The properties and microstructure of skim rubbers produced via CO₂ microbubbles (MBSL) were investigated in comparison with those produced by traditional processes. The MBSL exhibited smooth surface texture with enhanced tensile strength and thermal stability. Utilization of CO₂ as a sustainable feedstock to coagulate skim latex has a potential for not only diminishing the limitations caused by traditional processes but also highlighting an environmental-friendly and cost-effective process with improved product properties.

本研究开发了一种用于脱脂橡胶生产的创新CO _{2利用方法。}传统上，胶清橡胶是使用大量浓硫酸来凝固橡胶颗粒来生产的。加酸前需进行脱氨处理，以减少酸的使用量。然而，该工艺操作面积大、处理时间长、环境问题和健康危害。为了尽量减少这些缺点，作为本研究中的一种工艺强化技术，应用CO ₂微泡作为原料来减少氨，从而减少酸的添加量。_{研究了通过CO 2}微泡（MBSL）生产的胶清橡胶的性能和微观结构，并与传统工艺生产的胶清橡胶进行比较。MBSL 具有光滑的表面纹理，具有增强的拉伸强度和热稳定性。利用CO ₂作为凝固脱脂胶乳的可持续原料，不仅有可能减少传统工艺造成的限制，而且还可以突出环境友好且具有成本效益的工艺，并改善产品性能。
