EVA wireless glue binding hot melt adhesive evaluation report

In order to coordinate with the formulation of the industry standards for “bookbinding EVA hot melt adhesive use requirements and inspection methods”, relevant technical data in the standard are verified, the quality status of the current bookbinding EVA hot melt adhesive is ascertained, and the national printing standardization In March 2006, the Technical Committee organized the “Evaluation of EVA Hot Melt Adhesives for Bookbinding” to collect Wuxi City Wanli Bonding Material Factory and Guangzhou Fanghai Hotmelt Adhesive Manufacturing Co., Ltd. , Jinan Huafu Printing Materials Co., Ltd., Henkel Co., Ltd., Beijing Wensheng Printing Materials Co., Ltd., Sanhe Yanjiao Zhongqing Adhesives Co., Ltd., Zhengzhou Huimin Adhesives Co., Ltd., and Zhejiang Yida Adhesives Co., Ltd. Melt glue production companies in the eight kinds of offset paper binding glue and four kinds of coated paper binding glue, according to the technical requirements of the draft standard for a comprehensive test of the glue sample.

In order to ensure the fairness of the test, 12 rubber samples were numbered.

The main test program

1. The quality supervision and inspection center of the Chemical Industry Adhesives, which can produce the official test report of the State, tests the technical specifications of the glue samples, tests the 9 technical indicators of each 1 kilogram of 12 glue samples, and presents the formal technology. testing report.

2. Under the strong support and cooperation of Shenzhen Precision Machinery Co., Ltd., 12 kinds of glue samples were bound according to the requirements in the standard, and 180 sample books corresponding to 12 binding glue samples were made.

Third, according to the test method described in the standard test the relevant sample book.

Through the evaluation of the above process, a relatively complete set of technical data of book binding glue was obtained.

On November 3rd, a "Evaluation Conference on EVA Hot Melt Adhesives for Bookbinding" was held in Beijing to review and summarize evaluation activities.

Conclusions

The “Evaluation of EVA Hot Melt Adhesives for Bookbinding” organized by the National Standardization Technical Committee for Printing Standards, the Adhesive Testing Center of Chemical Industry, Shenzhen Precision Equipment Co., Ltd., and the Printed Products Quality Supervision and Inspection Center of the General Administration of Press and Publication, Changchun Yueming Under the cooperation of small-scale testing machine factory, Wuxi Wanli Bonding Material Factory, Guangzhou Fanghai Hot Melt Adhesive Manufacturing Co., Ltd., Shandong Xinhua Printing Factory Jinan Huafu Printing Material Co., Ltd., Henkel Corporation, Beijing Wensheng Printing Materials Co., Ltd., Sanhe Yanjiao Zhongqing Adhesives Co., Ltd., Zhengzhou Huimin Adhesives Co., Ltd. and Zhejiang Yida Adhesives Co., Ltd., under the guidance of relevant experts, received good results and met expectations. the goal of.

1. “Evaluation of EVA Hot Melt Adhesives for Bookbinding” is a technical evaluation organized to better define the “Usage Requirements and Test Methods for EVA Hot Melt Adhesives for Bookbinding” and will help the drafting group A more in-depth understanding of the wireless glue binding technology, through the evaluation of the first-hand technical data will be used for "bookbinding EVA hot melt adhesive use requirements and test methods," when the industry standard formulation reference to improve the quality of the standard Great benefit.

2. The evaluation results of “Evaluation of Bookbinding EVA Hot Melt Adhesives” show that the 12 adhesive samples submitted by the 8 hot melt adhesives companies that participated in the evaluation were bound according to the standard bookbinding technology and their binding strength was Can meet or exceed the "bookbinding EVA hot melt adhesive use requirements and test methods" industry standard strength requirements.

Third, according to the testing of the binding strength of 12 kinds of sample books, it is found that the binding strength of different books in each type of sample books is different; and the binding strengths of different pages of each sample book are also different. Therefore, when carrying out bookbinding production and binding quality studies, we should further look into the reasons.

Skills to solve.

4. In the “Evaluation of EVA Hot Melt Adhesives for Bookbinding”, the bookbinding strength tester designed and produced by the National Printing Standardization Technical Committee and the Changchun Yueming Small-scale Testing Machine Factory provides good testing tools for the evaluation activities. A blank in the current bookbinding field detection method has important significance for the book publishing, printing, and bookbinding industries in China through technical data research bookbinding technology, monitoring bookbinding strength, dataization, standardized production, and improving bookbinding quality.
