Hot-air/hot-steam process for the production of binderless wood fiber insulation boards using the Laccase-Mediator-System (LMS)

该转移项目的目的是为在木材纤维上应用漆酶介体系统(LMS)并用之前DFG项目中开发的热空气/热蒸汽工艺固化纤维找到最佳的科学和技术条件。为此，所获得的结果将从间歇工艺转移到与Pfleiander公司合作的连续工作系统中。转移项目还将侧重于基础研究，以了解热空气和热蒸汽应用过程中的物理过程以及LMS的相关行动模式。为了将该工艺扩大到工业规模，将仔细分析结果。本研究项目的技术目标是改造木纤维保温板的生产条件，使之符合LMS的要求，并集成热风/热蒸汽工艺技术，从而生产无粘结剂的木纤维保温板。该项目将持续36个月，因为原型工厂的设计和建造要求很高，需要一定的时间。热风/热蒸汽工艺生产LMS粘合木纤维绝缘板的应用将为白色生物技术提供一个全新的应用领域和来自绝缘行业的更多客户。为此，计划分析热风/热蒸汽工艺的物理功能和作用模式，以及它对LMS处理的木纤维之间的加性和粘结机理的影响。此外，还将调查化学木材成分在LMS行动和热空气/热蒸汽处理中的作用，并将其作为工艺流程的考虑因素。由于先前研究的积极结果，预计这一转移项目的成功前景很高。

The aim of the transfer project is to find optimal scientific and technical conditions for the application of laccase mediator systems (LMS) on wood fibers and curing the fibers with the hot-air/hot-steam process, which was developed in the preceding DFG projects.For this purpose, the results obtained will be transferred from the batch process into a continuous working system in collaboration with the Pfleiderer Company. The transfer project will also focus on basic research to understand the physical processes during hot air and hot steam applications and the related mode of action of the LMS. To scale up the process into industrial scale the results will be carefully analyzed. The technical objective of the research project is to modify the production conditions of the wood fiber insulation boards to the requirements of the LMS and to integrate the process technique of hot-air/hot-steam, which enable the production of binder-free wood fiber insulation boards. The duration of the project will be 36 months, as attempts to design and build the prototype plant are demanding and require a certain amount of time.The application of the hot-air/hot-steam process for the production of LMS-bonded wood fiber insulation boards are supposed to enrich white biotechnology with a completely new application field and additional customers from the insulation industry.For this purpose, it is planned to analyze the physical function and mode of action of the hot-air/hot-steam process and its influence on the ad- and cohesive mechanisms between the LMS-treated wood fibers. Also the role of the chemical wood components during LMS actions and the hot-air/hot-steam treatment will be investigated and has to be considered for the technical process.The prospect of success of this transfer project is expected to be high due to the positive results of the previos studies.
