Preparation and Sizing Performance of the Modified Collagen Surface Sizing Agent WANG Xue Chuan1,a, HAO Xiao Li1,b, QIANG Tao Tao1,c 1Shaanxi University of Science and Technology, Key Laboratory of Chemistry and Technology for Light Chemical Industry, Ministry of Education, Xi’an, Shaanxi, China aemail: wxc-mail@163.com, bemail: haoxiaoli111@163.com, cemail: qiangtt515@163.com Key words: collagen, graft modification, sizing agent, preparation, sizing performance Abstract.
Using collagen as the raw material, methyl acrylate and vinyl acetate as the soft and hard monomers, ammonium persulfate as the initiator, a surface sizing agent was prepared by the emulsion polymerization method to modified the collagen.
Based on the above all, a surface sizing agent was prepared by the emulsion polymerization method to modified the collagen, using the collagen as the raw material, methyl acrylate and vinyl acetate as the soft and hard monomers, ammonium persulfate as the initiator.
It can be seen from the data of Table 1 that the sizing agent emulsion which was prepared by using the collagen with hydrolysis 2h as raw materials was the most stable and had not any layering or precipitate phenomenon.

During the cooling, the microstructure of the material changes depending on the imposed cooling rate.
First, the experimental setup used to analyze the heat transfer on the interface of both materials is shown.

Introduction Steel and concrete continuous composite girders are widely used in multistory buildings and long span bridges due to the benefits of combining the two construction materials [1].
The mechanical behavior of the composite structure was not only determined by the properties of different materials, but also influenced by the connection structure between different materials.

Xu at East China University of Science and Technology computed the cooling degree coefficient and heat balance in 1999 [8].
Another example is for the type when the surrounding material has a much higher thermal conductivity than the studied material.
In this case, the surrounding material imposes the boundary temperature.

Gear material is steel and the module is 2.1e+011N/m^2, what is more, the ratio of Poisson is 0.28NA.
First enter COSMOS/Works module, second select materials, and third applied materials to all, then from the library file to the selected materials, finally OK.
Absolutely it does not exceed the material's yield stress 2.914 x 103.
At the same time, it can be checked in the both tables of the selected material that the allowable stress is 478MP, so it is a reasonable design.
