1 前言在水工金属结构闸门的设计中,支承结构设计是其中的一个重要环节,它必须同时满足“承载能力、耐磨性和使用寿命”三个方面。这几年,MGB的产生,解决了这个难题。2 MGB的性能MGB是一种工程塑料合金,主要是使用几种不同分子结构的单体,使用不同的催化剂和助催化剂来控制反应速度及分子量,通过阴离子聚合而得到不同分子量及不同分子结构的共聚高聚物,在此基础上,通过添加减磨剂和特殊合成的稀土化合
1 Introduction In the design of hydraulic metal gate structure, the support structure design is an important part of it, it must meet the three “bearing capacity, wear resistance and service life”. The past few years, the emergence of MGB, to solve this problem. 2 MGB performance MGB is an engineering plastic alloy, mainly using several different molecular structure of the monomer, the use of different catalysts and cocatalysts to control the reaction rate and molecular weight, by anionic polymerization to obtain different molecular weight and molecular structure Copolymer, on the basis of this, by adding anti-wear agent and special synthetic rare earth compound
