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.
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 performance.
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.
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
Descrtption 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.
