影响聚氨酯保温材料的使用寿命的因素有哪些
来源:/ 日期:2018-08-13 发布人:admin

聚氨酯保温材料一直以来都受到用户的赞许,它具有独特的性能优势,被作为一种优良的绝热保温材料而获得迅速发展,那么是什么原因让聚氨酯保温材料寿命下降呢?今天我在这里就给大家整理了关于聚氨酯保温材料寿命下降的相关资料,下面就跟我们一起来看一下吧。
Polyurethane insulation materials have always been praised by users, it has a unique performance advantage, as an excellent insulation material and has been developed rapidly. So what causes the life of polyurethane insulation materials to decline? Today, I am here to give you a collation of polyurethane insulation materials on the decline in life of the relevant inion, the following with us to have a look at it.
1、聚氨酯保温材料层偏心,即聚氨酯保温层与钢材料不同心,形成保温厚薄不均,严重者可使外层塑料软化而被损坏。
1. Polyurethane insulation material layer eccentricity, that is, polyurethane insulation layer and steel materials are not centric, forming uneven thickness of insulation, serious can make the outer plastic softening and damage.
2、使用不当而遭受破坏,在运输及安装过程中易受损伤,在埋地后距地面深度不够或上部土壤及道路较软,造成载重车辆碾压后被损坏。
2. It is easy to be damaged in the course of transportation and installation because of improper use. It is not deep enough from the ground after burial or the soft soil and road above it, resulting in the damage of heavy vehicles after rolling.

3、接口处理不当,在材料道敷设安装过程中,相接二根材料焊接不严密造成渗水,或在“补口”过程中操作不认真而造成外部污水渗入保温层等造成的破坏。
3. Improper interface treatment, in the course of laying and installing the material passage, the two connecting materials are not tightly welded, resulting in water seepage, or in the process of "filling" operation is not serious, resulting in external sewage infiltration insulation layer damage.
4、使用的塑料和聚氨酯保温材料不合理,如经常发现使用分拣杂乱的回收塑料,经过挤出成形后的塑料材料不能充分被塑化而致使外材料劣化。聚氨酯保温材料密度低造成强度低而在搬运过程中就已损坏,另外体系中含有游离酸太高,造成对钢材料外壁的腐蚀等。
4. The use of plastics and polyurethane insulation materials is unreasonable, such as the use of sorted recycled plastics, after extrusion molding of plastic materials can not be fully plasticized and resulting in deterioration of external materials. Low density of polyurethane insulation material results in low strength and has been damaged in the process of transportation. In addition, free acid is too high in the system, resulting in corrosion of steel materials.
