By different kinds of experimental methods we got some new understanding for the action and mechanism of bonding clay for high strength shell mould. Then we recommend the alumina, instead of silica powder and other kind of clays, to be used for high strength shell mould production, and thus substantially improve the high temperature characteristics of the shell mould. Instead of ammonium chloride the polymerism alumium chloride is used as hardening agent, thus we greatly improve the working condition of the...

Wood extractives exhibit significant effects on wood properties and hence its utilization. They also play an important role on the chemota-xonomy of tree species. Wood extractives are not only closely correlated to the characteristic color, odor, taste and durability of wood, but can also profoundly affect a number of physical, mechanical, and chemical properties of wood.

Wood extractives exhibit significant effects on wood properties and hence its utilization. They also play an important role on the chemota-xonomy of tree species. Wood extractives are not only closely correlated to the characteristic color, odor, taste and durability of wood, but can also profoundly affect a number of physical, mechanical, and chemical properties of wood. Therefore, wood extractives are largely responsible for the processing and utilization of wood.Wood extractives can reduce the shrinkage and recovery of wood during drying, enhance the dimensional stability of wood, and contribute to resistance to insect and fungal attack. In some instances, wood extractives from a coating on the cell wall and over the pit apertures, interfering with the permeability and penetrability of the wood. So that the shrinkage during drying on one hand, and the penetration of some preservative chemicals on the other, can be affected.In wood board industries, wood extractives can hinder the satisfactory adh of the glue to the wood surface or they may react with the glue to prevent satisfactory polymerization and setting. Sugars, tannins, and phenolic extractives can affect the hardening of cement in the manufacture of wood-cement boards. Also, certain wood extractives can affect the polymerization of the plastic component of wood-plastic composites.The presence of polyphenolic extractives in the cell contents can significantly affect both the behavior of wood during pulping, and the behavior of pulp during the manufacture of paper. Some inhibit pulping reactons, increase chemical consumption, reduce the yield of pulps and lower its quality, cause considerable color changes and increase bleach requirements, and also affect the recovery of pulping chemicals. Pitch problems and loss of absorbency in wood pulps are also due to the extractives. Some accelerate the blocking of pipes and corrosion of pulping -equipments.An in depth study of wood extractives will provide a better understanding of their effects on wood perties and will also assist the wood "industries to adopt effective approach in controlling or reducing their deleterious effects. In addition,there is evidence that the more rapid the growth , the lower the extractives contents, so that silvicultural and forest management practices may be used to overcome the deleterious extractives problems.

木材浸出物对于木材材性和木材利用都有重要影响,而且在树木化学分类上也有重要意义。木材浸出物不仅与木材的色、香、味和腐朽性有着密切关系,而且对于木材的物理力学性质和化学性质都有重要影响,因而对于木材的加工和利用关系极大。 木材浸出物能减少木材的干缩,增强木材的尺度稳定性,并赋予木材抵抗病虫侵害的能力。沉积在细胞壁和纹孔口上的浸出物,阻碍了木材的渗透性与可浸注性,因而影响了木材的干燥和防腐处理。 在人造板工业中,木材浸出物常影响胶合剂的有效胶着或胶的聚合固化。糖类、单宁和酚类浸出物能影响水泥刨花板制造过程中水泥的凝固。有些木材浸出物还能影响木材塑料复合材(WPC)中塑料的聚合。 木材组织中含有的多元酚类浸出物,在制浆和造纸过程中,都有重要影响。有些能抑制制浆反应,增加药物消耗,井降低纸浆得率和质量,颜色深暗,不容易漂白,而且影响制浆药物的回收。纸浆的树脂障碍和吸收性能也都受木材浸出物的影响。有些多元酚类浸出物并能与制浆药物中的碱土金属形成不溶的络合物,堵塞管道,加速制浆设备的腐蚀。 对木材浸出物的深入研究,将能较充分地了解木材浸出物对于木材材性的影响,也将有助于木材工业采取有效措施,控制或减少这些有害影响。此外,...
