橡胶制品与金属粘结的镶嵌塑压工艺技术研究

近年来,水下应用技术发展迅猛,水下作业设备的性能不断提高,从而需要气密性更高的配套零部件。但由于金属与橡胶(或树脂)材料的热膨胀系数不同,所以在镶嵌塑压成型以后,成型零件的气密性较差,无法满足深水作业环境的要求。而将开姆洛克(CHEMLOK)热硫化胶粘剂应用于镶嵌塑压过程,可以解决上述问题,使零件的气密性得到较高的提升。     

Preparation of Ultra-High-Speed Casein Trade Mark Adhesive

In present trade mark adhesives for beer bottle labeling are mostly prepared based on starch, polyvinyl formal and their derivants ,but they can only be applied to the labeling speed of 20 000 bottle/h and their water proofness are not satisfactory, especially when the water temperature is 0℃ below. The application of metal foil requires that sealing and labeling must be finished at the same time, but different penetrating speed of water in metal foil and paper label causes different drying speed, and also, the labeling speed and need of iced beer are increasing now, so these changes result in more strict requirements for adhesive.     

PVC人造革静电植绒胶调制方法的改进

为简化PVC人造革静电植绒胶的调制工艺，用高纯度的水及在线自制的N－羟甲基丙烯酰胺作交联剂，免去除阻聚剂的方法，所得的聚丙烯酸酯乳液在调胶时只加入氨水即可，无须加入三聚氰胺。     

FLOCKING OF MULTI-AGENT DYNAMIC SYSTEMS WITH GUARANTEED GROUP CONNECTIVITY*

This paper investigates distributed flocking problem where the information exchange among agents is modeled by the communication topology changing with time. Previous research on this problem establishes group stabilization by assuming that the dynamic topology is connected all the time, which however cannot be guaranteed by most proposed distributed control laws. In this paper, a distributed algorithm to distill a necessary subgraph of the initial communication topology is presented. This subgraph covers all the vertices of the communication topology and is proved to be connected as long as the initial communication topology is connected. A distributed control law is then designed to pursue the flocking motion while preserving all the edges in this subgraph. In this way, connectivity can be preserved all the time, and flocking problem is thus solved only provided the initial communication topology of multi-agent system is connected.

VEA烟胶系列产品的可行性分析

一、概述：目前我国卷烟工业生产使用的粘合剂均为聚醋酸乙烯乳液白乳胶，由于该原料的来源、运输、贮存不稳定，在生产和布局上受到极大限制，并在使用过程中还存在很多问题，特别是对高速机型的适应性方面，显得不够供应，直接影响卷烟工业的生产。目前研制开发成功的VEA烟胶系列产品填补了这一空白，为卷烟工业的发展作出了积极贡献。

玉米淀粉粘合剂的制备与前景

<正> 瓦楞纸板箱是国内外广泛使用的纸箱包装材料,制造瓦楞纸板必须用粘合剂来粘接纸面和瓦楞介质。几十年来,我国生产瓦楞纸板一直用水玻璃(即泡花碱,主要成分为硅酸钠)作粘合剂,水玻璃具有干燥快、使用简便、成本低等优点,因此沿用至今。但水玻璃又有耐湿性差,脆性大,重量重,有腐蚀性,耐压性差等缺点,国外早在五十年代就已将其废除,我国也从1984年起决定将其淘汰。目前,在制作普通瓦楞纸板方面,水玻璃正在逐渐被玉米淀粉系列粘合剂所取代。
