This book was released on 2019-03-05 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: At present, the use of polymer composites filled with wood (WPC) is becoming increasingly popular. In particular, flooring of terraced premises, siding, decorative fences, fence systems, steps, universal profiles, among others are made from WPC. In 1977, the first enterprise for the production of WPC appeared in Sweden. The first experience was not very successful – the demand turned out to be low, and the wear of technological equipment was very high. Therefore, developments in this field were resumed only in the 1990s and continue to this day. This book describes the basic physical and mechanical properties of modern WPC, such as tensile and compression strength, and hardness. Also, the influence of climatic factors on the performance properties of products from WPC is described, while the thermal and rheological properties of WPC materials are considered, which directly affect the consumer characteristics of the products. The book contains theoretical developments related to the prediction of the mechanical and thermal properties of polymers and composites. The Van der Waals volume and the energy of the intermolecular interaction are estimated. This book will be of interest to representatives of the WPC market, designers, and architects, as well as technology engineers, students and post-graduate students of higher educational institutions in the fields of chemistry and physics of composite polymer materials.

Download or read book Improvement of selected properties of Wood Polymer Composites WPC Silane modification of wood particles written by Timo Grüneberg and published by Cuvillier Verlag. This book was released on 2010-11-22 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood Polymer Composites are a new group of hybrid materials, which combine the advantages of synthetic polymers such as polyolefines and natural polymers such as wood; whereas the synthetic polymer is used as matrix material and the wood as reinforcement material or filler. As matrix material, principally every thermoplastic polymer with a processing temperature below 200°C can be used due to the temperature sensivity of wood. Wood Polymer Composites are processed typically with processing technologies from the plastic industry such as extrusion and injection molding. The present study was conducted to explore the possibility of wood particle modification with different types of silanes. It was the aim to contribute the silanes as compatibilizers or coupling agent and therefore improve the mechanical properties and the resistance against water. Norway spruce (Picea abies) as representative wood species was used in three different particle types. The size distribution for the wood particles ranges from 70-2500 µm. Four commercial available silanes with various functional groups (amino, di-amino, alkyl) were used as modification agents. The concentrations varied between 1.5%, 3.0%, 4.5% and 7.5%. As reference system commonly used maleated acid anhydride based coupling agents were used. The pre-treated wood particles were compounded via extrusion with polypropylene and samples were produced via injection and compression molding. The following properties were tested; tensile, bending, and impact strength, water uptake (cold and boiling water test), descent rate, weathering tests and durability test against basidiomycetes. SEM-EDX investigations proved the presence of silane either in the cell wall structure, or on the wood particle surface. Due to the structure and the functionality of the silanes it was expected that the silane treated wood particles are able to improve the mechanical properties. It was shown that the silanes had no significant effect as compatibilizer or coupling agent. The mechanical properties strongly increase with the usage of coupling agent. Both coupling agents were based on maleic acid anhydride grafted on a polymer backbone, whereas Type I reaches an optimum regarding the mechanical properties at 3%, the coupling agent Type II still improves the mechanical properties up to a ratio of 4.5% with no clear optimum. The silane pretreatment influences the improvement not significantly, compare to the improvement caused by the coupling agent. The used wood particles showed mechanical degradation during the compounding process. The biggest degradation was monitored for the wood particles of Lignocel® Type 9. Due to its fine structure it can be assumed that the Arbocel® C100 wood particles consist of only cell wall fragments of the wooden cell wall, which express a better resistance against mechanical destruction during the process. The Wood Polymer Composites showed a lower decay rate compared to solid wood. The moisture content within the Wood Polymer Composite samples ranges at the low optimum level for fungi attack and were not significantly improved by an accelerated wetting before the test. The core remains relatively dry. The main protection seems to come from the encapsulation by the polymer. The weathered Wood Polymer Composite samples showed a strong color change within a relatively short period of exposure. The color changed independently from the silane type or the silane ratio. Also an increase of cracks and gaps on the sample surface was observed compared to the unexposed sample and the pure polymer reference.

This book was released on 2018-01-11 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal is the product of plants, mainly trees that died tens or hundreds of millions of years ago. Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. Coal is used primarily as an energy source, either for heat or electricity. It was once heavily used to heat homes and power locomotives and factories. Bituminous coal is also used to produce coke for making steel and other industrial process heating. Lignin is a constituent of the cell walls of almost all dry land plant cell walls. It is the second most abundant natural polymer in the world, surpassed only by cellulose. Lignin is found in all vascular plants, mostly between the cells, but also within the cells, and in the cell walls. Wood is an aggregate of cells essentially cellulose in composition, which are cemented together by a substance called lignin. The cells are made of three substances called cellulose (about 50 percent), lignin (which makes up a fifth to a quarter of hardwoods but a quarter to a third of softwoods), and hemicellulose. Rosin refers to an extraction process that utilizes a combination of heat and pressure to nearly instantaneously squeeze resinous sap from your initial starting material In India's energy sector, coal accounts for the majority of primary commercial energy supply. With the economy poised to grow at the rate of 8-10% per annum, energy requirements will also rise at a reasonable level. The Indian coal industry aspires to reach the 1.5 billion tonne (BT) mark by FY 2020. In fore-coming years, the industry will naturally need to focus on building on the success, and be on track for reaching the FY 2020 goal. One of the primary goals of the Government of India is to ensure that it is able to meet the country's power generation needs. Another aim is to lower the country's reliance on coal imports by boosting the coal production quickly. The Major contents of the book are Coal, Analysis of Coal and Coke, Cotton, Lignin and Hemicelluloses, Degradation of Wood, CCA-Treated Wood, Wood-Polymer Composites, Lignocellulosic-Plastic Composites from Recycled Materials, Chemical Modification of Wood Fiber, Delignification of Wood with Pernitric Acid, Rosin and Rosin Derivatives, Polymerizable Half Esters of Rosin and Photographs of Plant & Machinery with Supplier’s Contact Details. It will be a standard reference book for professionals, entrepreneurs, those studying and researching in this important area and others interested in the field of these industries.
