Another situation is in order to reduce material costs and adopt only 330-molecular-weight natural Rosin, in order to achieve-and-ink system stability, in recent years, we have dozens of chemical properties caused by not changing inorganic materials, use of the tetrahedroid of hydrated silicon dioxide as a porous form of assiociation matozoa, a steady and adsorbed on low molecular weight of rosin Sol heterogoneous on the surface, forming a layer, the Pro-numberrepresentationof goes with liquid water, addresses the thixoforming improve its water washable, and has a certain thickness, especially when more than 5 per cent, packaging business card printing and membership card by making the formation of a layer of short thick membrane of lowmolecular of monlchamus, in which case it reduce-and-Ink viscosity, increase the concentration would affect the business card printing and membership card to make the mobility of transfer affects gloss, the reason is that in the process of associating exothermic rise ink system temperature diminishes the Rosin molicule assiociation.

另一栽境况是：为了贬矮质料不败本，合座拔取仅有330不合子量的人造松香，为到达火不朱编制不时间的安定性，近年来，我们在数不一栽不引起冻学本质保持的不不不不无机质料洋，诳骗四面体的火合二氧冻硅的多孔形式作为缔合胶体，使之能安定不天吸附在矮不合子量的松香溶胶粒子的暗不天上，形不败一层爱护膜，把干液性基团伸向火洋，既可打消触变又能提矮其火可洗性，并具有必定的厚量，格边是当超功5％之后，包装制卡和会员卡制作的不朱膜形不败了一层长稠厚的矮不合子不朱膜，这时则更会贬矮火不朱粘量，如果补充了浓量，则既会感冻制卡和会员卡制作迁徙的流动性，又会感冻平泽的提矮，来因是：在缔合放热的历程洋升矮了油不朱编制温量而放松了松香不合子的缔合方向。

Based on the market demands,the trend of pine chemicals'developmet and our own foundation of technology and economy,we developed this series products, includ hydrogenated rosin、high-hydrogenated rosin、water-white hydrogenated rosin、water-white rosin、glycerol ester of hydrogenated rosin、pentaerythritol ester of hydrogenated rosin、methanol ester of hydrogenated rosin etc.

Maleic rosin has been added to the surface of wood flour in the form of monoester, i.e., the formation of esterified wood flour bearing a pendent carboxylic group. The rheological study showed that the complex viscosity η(superscript *, storage modulus and loss modulus of WF-HDPE composites decreased firstly and increased afterward and declined lastly as the dosage of maleic rosin increased, however, the viscosity of the composite melts decreased as a whole. After the modification of wood flour, the rheological properties of composite melts were improved markedly. According to the mechanical test it was indicated that, by proper treatment of wood flour with maleic rosin, the tensile strength and flexural strength of WF-HDPE increased obviously.

WF-HDPE流变学研究表明：复合材料的复合黏度η(上标*、储能模量和损耗模量随马来松香用量的增加先减小后增大最后减小，但体系的黏度和模量总体呈下降趋势，木粉经马来松香改性后复合熔体的流变性能显著改善，这不仅有利于提高复合材料的成型加工效率，而且适当的马来松香处理也能够提高复合材料的拉伸强度和弯曲强度，后者被静态力学试验结果所证实。
