聚乙烯闭孔泡沫板是国内一种新型的接缝止水材料，已广泛应用于公路，道桥胀缝、立交桥、高速公路、机场跑道、地道桥、地下通道、地铁、桥头挡阻墙接缝、公路两侧护坡、路基护坡等混凝土工程中的接缝土工程中的接缝及止水材料，电厂防潮闸、冷却塔、建筑等工程中混凝土接缝、胀缝及止水材料混凝土公路、高架桥梁、涵洞隧道、机场跑道、堤坝护坡等水利电力混凝土工程中。

Polyethylene foam plate is one of the new joint sealing material, has been widely used in highway, joint and sealing material bridge expansion joints, overpass, highway, airport runway, bridge, tunnel, subway, underground channel bridge block wall joint, on both sides of the road slope and subgrade slope and concrete engineering in seam soil engineering, power plant, cooling tower, floodgate construction engineering concrete joints, expansion joints and sealing material of concrete road, elevated bridge, culvert tunnel, airport runway, dam slope protection of water conservancy and electric power engineering concrete.

聚乙烯闭孔泡沫板施工简便，不污染环境，便于运输储存，材料无浪费，是软木、木材、橡胶等其它止水和嵌缝材料的良好替代物，将为国家节省大量的木材，减少环境污染具有不可估量的社会效益。是目前混凝土工程中最理的接缝材料。
Polyethylene foam board, simple construction, no environmental pollution, convenient transportation and storage, no waste of materials, is a good substitute for cork, wood, rubber and other sealing and sealing material, will save a lot of wood, reduce environmental pollution has immeasurable social benefits. It is the most reasonable joint material in concrete engineering at present.
二、聚乙烯闭孔泡沫板特点
Two. Characteristics of polyethylene closed cell foam board
1、闭孔泡沫板密度小、回复率高、具有独立的气泡结构。
1, the closed cell foam board has small density, high recovery rate, and has independent bubble structure.
2、闭孔泡沫板表面吸水率低，防渗透性能好。
2, the closed cell foam board surface water absorption rate is low, good anti permeability perbance.
3、闭孔泡沫板耐酸、碱、盐、油等有机溶剂腐蚀，耐老化性能优良。
3, closed cell foam board acid, alkali, salt, oil and other organic solvents corrosion, good aging resistance.
4、闭孔泡沫板高温时不流淌，低温时不脆裂。

4, closed cell foam board does not flow at high temperature, not brittle cracking at low temperature.

三、聚乙烯闭孔泡沫板的分类
Three. Classification of polyethylene closed cell foam board
聚乙烯闭孔泡沫板分为两种， L-600高发泡泡沫板和L-1100低发泡沫泡沫板。
PE closed cell foam board is divided into two kinds, L-600 high incidence foam board and L-1100 low hair foam foam board.
四、L-600聚乙烯闭孔泡沫板的说明
Debion of four and L-600 polyethylene closed cell foam board
L-600聚乙烯闭孔隙泡沫板也被称为高发泡泡沫板，该泡沫板的常用规格为：1.2m×2m×20mm（30mm）和1m×2m×20mm（30mm），它的颜色为黑色，硬度高，密度大，表面有气泡结构。
L-600 polyethylene closed pore foam board is also called high foaming foam board. The common specifications of the foam board are: 1.2m x 2m x 20mm (30mm) and 1m * 2m * 20MM (30mm). The color of the foam board is black, hardness is high, density is big, and the surface has bubble structure.
