Evaluation report on EVA type hot melt adhesive for wireless binding in order to cooperate with the formulation of the industry standard "use requirements and inspection methods of EVA type hot melt adhesive for book binding", verify the relevant technical data in the standard, and find out the current quality status of EVA type hot melt adhesive for book binding, the National Printing Standardization Technical Committee organized the "evaluation of EVA type hot melt adhesive for book binding" in March, 2006, Wuxi Wanli adhesive material factory, Guangzhou FangHai hot melt adhesive manufacturing Co., Ltd., Jinan Huafu printing materials Co., Ltd., Henkel Co., Ltd., Beijing Wensheng printing materials Co., Ltd., Sanhe Yanjiao Zhongqing adhesive Co., Ltd., Zhengzhou Hui Gelatin Industry Co., Ltd., and Zhejiang Yida adhesive Co., Ltd., which are widely used in the domestic market, were recruited Scope of application of the tensile testing machine: the tensile testing machine is also known as 8 kinds of offset paper binding adhesive and 4 kinds of coated paper binding adhesive from 8 hot melt adhesive manufacturers such as the tensile testing machine Co., Ltd., and the adhesive samples have been comprehensively tested according to the technical requirements in the draft standard

in order to ensure the fairness of the test, 12 kinds of rubber samples were numbered

main test procedures

I. entrust the chemical industry adhesive quality supervision and testing center that can produce the national formal test report to test the technical indicators of the adhesive samples, test 9 technical indicators of 12 kinds of adhesive samples of each 1kg, and issue the formal technical test report

II. With the strong support and cooperation of Shenzhen Jingda Machinery Co., Ltd., 12 kinds of adhesive samples were bound according to the requirements of the standard, and 180 sample books corresponding to the 12 kinds of binding adhesive samples were made

III. test relevant sample books according to the test method described in the standard

through the evaluation of the above processes, a set of relatively complete technical data of book binding adhesive was obtained

on November 3, the "evaluation and summary meeting of EVA hot melt adhesive for book binding" was held in Beijing to review and summarize the evaluation activities

concluding comments

organized by the National Technical Committee for printing standardization, "the rise in the prices of various raw materials has brought great pressure on the production of Chalco Shanxi new materials Co., Ltd." evaluation of EVA hot melt adhesive for book binding, with the cooperation of the chemical industry adhesive testing center, Shenzhen Jingda equipment Co., Ltd., the printing quality supervision and testing center of the General Administration of publication, and Changchun Yueming small testing machine factory, With the enthusiastic participation of Wuxi Wanli adhesive material factory, Guangzhou FangHai hot melt adhesive manufacturing Co., Ltd., Shandong Xinhua Printing Factory Jinan Huafu printing material Co., Ltd., Henkel Co., Ltd., Beijing Wensheng printing material Co., Ltd., Sanhe Yanjiao Zhongqing adhesive Co., Ltd., Zhengzhou Hui Gelatin Industry Co., Ltd. and Zhejiang Yida adhesive Co., Ltd., and under the guidance of relevant experts, good results have been achieved, The expected purpose has been achieved

I. "evaluation of EVA type hot melt adhesive for book and journal binding" is a technical evaluation organized to better formulate the industry standard for use requirements and test methods of EVA type hot melt adhesive for book and journal binding, which will help the standard drafting group to have a deeper understanding of wireless adhesive binding technology, The first-hand technical data obtained through the evaluation can be used as a reference for the formulation of the industry standard "EVA hot melt adhesive for book binding has no great impact on processability; use requirements and test methods", which is of great benefit to improve the quality of the standard

II. The evaluation results of "evaluation of EVA type hot melt adhesive for book binding" show that the binding strength of 12 kinds of adhesive samples submitted by 8 hot melt adhesive factories participating in the evaluation, which are bound according to the standard book binding process, can meet or exceed the strength index required by the industry standard "application requirements and inspection methods of EVA type hot melt adhesive for book binding"

III. according to the test on the binding strength of 12 kinds of adhesive sample books, it is found that the binding strength of different books in each type of sample books is different; The binding strength of different pages of each sample book is also different. Therefore, in the study of book binding production and binding quality, we should further find out the causes and solve them from the

technique

IV. in the "evaluation of EVA hot melt adhesive for book binding", the book binding strength tester designed and produced jointly by the National Printing Standardization Technical Committee and Changchun Yueming small testing machine will produce impact and even spark. It provides a good testing tool for evaluation activities and fills a gap in the current testing means in the field of book binding, which is of great significance to China's book publishing It is of great significance for the printing and binding industry to study book binding technology through technical data, monitor book binding strength, realize data-based and standardized production, and improve book binding quality
