Tackiness of a biodegradable binder for erosion control mulch

斜坡上的土壤侵蚀是雨水从斜坡上排出而引起的一种自然现象。用植被保护层覆盖斜坡可以防止雨水造成的土壤颗粒松动，防止它们被冲下斜坡。侵蚀控制毯(ECBVerdyol)是一家生产防腐产品、液压覆盖和植被恢复产品的全线制造商。该公司寻求进入一项新业务，该业务将提供一种基于木质素的粘结剂系统，以补充欧洲央行的可喷洒地膜产品。ECBVerdyol没有保持地膜系统所需的粘结剂系统，特别是在下雨时倾斜的土壤，以防止侵蚀。为了改善地膜的内部结合，可以添加粘结剂。目前用于地膜的最好的商业产品是基于昂贵的表面化学衍生成分。因此，这项建议的目标是开发一种基于木质素和甘油等生物可再生成分的粘结剂系统。建议使用由AB Hinton的West Fraser制造的、由ECBVerdyol提供的低灰分和高灰分木质素，并与天然增塑剂(甘油)混合使用。将测试水、甘油和木质素的混合物的粘度和粘性。上述混合物与地膜的混合物将通过测量休止角来测试静摩擦力。测试混合物的实验结果将与含有Finn E-Tack的商业产品作为参考进行比较。调查结果将为ECB Verdyol提供有关木质素-增塑剂-地膜比率的数据，并将使该公司能够用环保的木质素粘结剂取代基于石化的成分，如Finn E-Tack。该项目所获得的实验结果将有助于该公司决定以生物可再生成分为基础的覆盖系统高粘度粘结剂的经济放大生产。

Version française disponibleSoil erosion on slopes is a natural phenomenon caused by the rainwater draining down the slope. Covering theslope with a protective layer of vegetation can stop loosening soil particles due to rain and preventing themfrom being washed down the slope. Erosion Control Blanket (ECBVerdyol) is a full line manufacturer oferosion control products, hydraulic mulches, and revegetation products. The company seeks to enter a newbusiness that would supply a lignin-based binder system to supplement ECB's sprayable mulch products.ECBVerdyol does not have a binder system that is needed to keep the mulch systems in place, especially onsloped earth when exposed to rain to prevent erosion. To improve the internal bonding of mulch, bindingagents can be added. The best commercial product that is being used in mulches is based on expensivepetro-chemically derived components. Therefore, the objective of this proposal is to develop a binder systembased on bio-renewable components such as lignin and glycerol.It is proposed that low and high ash content lignin made by West Fraser in Hinton, AB and supplied byECBVerdyol will be used and mixed with a natural plasticizer (glycerol). Mixture of water, glycerol, and ligninwill be tested for viscosity and tackiness. Blends of the above mixture with mulch will be tested for staticfriction by measuring the angle of repose. The experimental results of the tested mixtures will be compared tomulches mixed with a commercial product containing FINN E-Tack as a reference. The results of theinvestigations will provide data for ECBVerdyol with regard to the lignin-plasticizer-mulch ratio and will allowthe company to replace petrochemical-based components such as FINN E-Tack with the environmentallyfriendly lignin-based binder. The experimental results obtained from this project will be essential to help thecompany to make a decision on an economical scale-up production of a high-tack binder for the mulch systemsbased on bio-renewable components.
