聚乙烯閉孔泡沫板是國內(nèi)一種新型的接縫止水材料，已廣泛應(yīng)用于公路，道橋脹縫、立交橋、高速公路、機(jī)場(chǎng)跑道、地道橋、地下通道、地鐵、橋頭擋阻墻接縫、公路兩側(cè)護(hù)坡、路基護(hù)坡等混凝土工程中的接縫土工程中的接縫及止水材料，電廠防潮閘、冷卻塔、建筑等工程中混凝土接縫、脹縫及止水材料混凝土公路、高架橋梁、涵洞隧道、機(jī)場(chǎng)跑道、堤壩護(hù)坡等水利電力混凝土工程中。
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.
聚乙烯閉孔泡沫板施工簡(jiǎn)便，不污染環(huán)境，便于運(yùn)輸儲(chǔ)存，材料無浪費(fèi)，是軟木、木材、橡膠等其它止水和嵌縫材料的良好替代物，將為國家節(jié)省大量的木材，減少環(huán)境污染具有不可估量的社會(huì)效益。是目前混凝土工程中最理的接縫材料。
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、聚乙烯閉孔泡沫板特點(diǎn)
Two. Characteristics of polyethylene closed cell foam board
1、閉孔泡沫板密度小、回復(fù)率高、具有獨(dú)立的氣泡結(jié)構(gòu)。
1, the closed cell foam board has small density, high recovery rate, and has independent bubble structure.
2、閉孔泡沫板表面吸水率低，防滲透性能好。
2, the closed cell foam board surface water absorption rate is low, good anti permeability perbance.
3、閉孔泡沫板耐酸、堿、鹽、油等有機(jī)溶劑腐蝕，耐老化性能優(yōu)良。
3, closed cell foam board acid, alkali, salt, oil and other organic solvents corrosion, good aging resistance.
4、閉孔泡沫板高溫時(shí)不流淌，低溫時(shí)不脆裂。
4, closed cell foam board does not flow at high temperature, not brittle cracking at low temperature.
三、聚乙烯閉孔泡沫板的分類
Three. Classification of polyethylene closed cell foam board
聚乙烯閉孔泡沫板分為兩種， L-600高發(fā)泡泡沫板和L-1100低發(fā)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聚乙烯閉孔泡沫板的說明
Debion of four and L-600 polyethylene closed cell foam board
L-600聚乙烯閉孔隙泡沫板也被稱為高發(fā)泡泡沫板，該泡沫板的常用規(guī)格為：1.2m×2m×20mm（30mm）和1m×2m×20mm（30mm），它的顏色為黑色，硬度高，密度大，表面有氣泡結(jié)構(gòu)。
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.
