Implementation of new wood preservatives

适当的木材处理对于延长木制品的使用寿命至关重要，特别是户外应用。最常见的保存方法是压力处理过程，其中木材防腐化学品被强制渗透到木材的细胞结构中，形成抵御风化和生物变质的屏障。由于越来越多的环境问题和越来越严格的政府法规，斯特拉-琼斯公司，一个领先的北美木制品制造商，正在寻求开发更低危害的防腐剂，以取代目前使用的防腐剂，以尽量减少处理过程对环境的影响。该项目的目标是在商业规模上实施两种新的环境友好型防腐剂：1,5 -二氯-2-正辛基-4-异噻唑啉-3- 1 （DCOI）和微粉化铜唑（MCA）。所有与这两种防腐剂应用相关的问题都将得到解决，包括新配方的开发，处理工艺的优化，DCOI和MCA对加拿大木材腐烂真菌的功效测试，以及两种防腐剂在处理和储存容器中的稳定性。预期的结果将填补DCOI和MCA在木材处理应用商业化方面的知识空白，并提供更环保和优化的处理工艺，最大限度地减少浸出和气味释放。这些新的知识和协议将帮助Stella-Jones开发和实施新的更环保的防腐剂，将这些防腐剂的应用扩展到整个木材处理行业，最重要的是帮助政府制定新的指导方针和政策，所有这些对加拿大都非常重要。实现这些目标还将使加拿大成为世界上有意识的环境保护的领导者。

Proper wood treatment is essential for extending the service life of wood products, particularly for outdoor applications. The most common approach for preservation is a pressure treatment process, in which wood preservative chemicals are forced to penetrate the cellular structure of the wood, forming a barrier against weathering and bio-deterioration. Due to the growing environmental concerns and increasingly strict governmental regulations, Stella-Jones Inc., a leading North American manufacturer of treated wood products, is pursuing to develop less hazardous preservatives to replace currently used ones to minimize the impact of the treatment processes on the environment. The objective of the project is to implement two new environmentally friendly preservatives, iso-thiazolone, 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOI) and micronized copper azole (MCA) at commercial scale. All issues associated with the application of the two preservatives will be addressed, including new formulation development, treating process optimization, efficacy test of DCOI and MCA against wood decay fungi on Canadian wood species as well as the stability of two preservatives in both treating and storage vessels. The anticipated outcomes will fill the knowledge gaps in the commercialization of DCOI and MCA' applications in wood treatment, and provide a greener and optimized treating processes with minimum leaching and odor releasing. These new knowledge and protocols will help Stella-Jones develop and implement new and more environmentally friendly preservatives, extend the application of such preservatives to the whole wood treatment industry, most importantly help government establish new guidelines and policies, all of which are extremely important to Canada. Achieving such goals will also position Canada as a leader in the world for mindful environment protection.
