In order to cooperate with the formulation of the industry standard "Use Requirements and Inspection Methods of EVA Hot Melt Adhesives for Binding", the relevant technical data in the standard were verified, and the quality status of the current EVA hot melt adhesives for bookbinding was identified. National Printing Standardization 2006 In March, the technical committee organized the "EVA Hot Melt Adhesive for Book Binding", and the hot melt adhesive production company conducted a comprehensive test in accordance with the technical requirements of the draft standard among eight offset paper binding adhesives and four coated paper binding adhesives. sample.
To ensure fair testing, 12 rubber samples were numbered.
main test procedure
1. The Chemical Adhesive Quality Supervision and Inspection Center can issue official national test reports, test technical indicators of glue samples, detect 9 technical indicators per 1 kg of 12 glue samples, and issue formal technical specifications. Test Report.
2. With the strong support and cooperation of Shenzhen Precision Machinery Co., Ltd., 12 kinds of glue samples were bound according to the standard requirements, and 180 sample books corresponding to the 12 glue samples were produced.
3. Test the relevant sample books according to the test methods described in the standard.
Through the evaluation of the above processes, a relatively complete set of technical information on book binding glue is obtained.
On November 3, "EVA Hot Melt Adhesives for Book Binding" was held in Beijing to review and summarize the evaluation activities.
in conclusion
The "EVA Hot Melt Adhesive for Book Binding" organized by the National Printing Standards Standardization Technical Committee, the Chemical Adhesive Testing Center, Shenzhen Precision Equipment Co., Ltd., and the Print Quality Supervision and Inspection Center has received good results under the guidance of relevant experts. met expectations. The goal.
1. "Evaluation of Hot Melt Adhesives for EVA Binding" is a technical evaluation organized to better define the "Requirements and Test Methods of Hot Melt Adhesives for EVA Binding", which will help the drafting group to have a deeper understanding of wireless technology . Glue binding technology, through the evaluation of first-hand technical data, will be used as a reference in the formulation of the industry standard of "Binding EVA Hot Melt Adhesive Use Requirements and Test Methods", which is of great benefit to improving the quality of the standard.
2. The evaluation results of "Evaluation of EVA Hot Melt Adhesives for Book Binding" show that the 12 adhesive samples submitted by the 8 hot melt adhesive companies participating in the evaluation are all bound according to the standard binding process, and their binding strength can reach or exceed "Binding EVA Hot Melt Adhesives". Requirements for the use of melt adhesives and test methods "industry standard strength requirements.
3. According to the test of the binding strength of 12 kinds of sample books, it is found that the binding strength of different books in each sample book is different; and the binding strength of different pages of each sample book is also different. Therefore, in the study of bookbinding production and bookbinding quality, the reasons should be further searched and solved technically.
4. In "Evaluation of EVA Hot Melt Adhesive for Binding", the binding strength tester designed and produced by the National Printing Standardization Technical Committee and Changchun Yueming Small Test Machine Factory provides a good test tool for evaluation activities. Researching binding technology through technical data, monitoring binding strength, digitization, and standardization of production, and improving binding quality are of great significance to a blank in the current binding field detection methods in my country's book publishing, printing, and binding industries.
