多层热合聚乙烯保温管壳
产品简介：
多层热合聚乙烯管壳，是在机械热合中经过高温压缩而成型，经热电处理,机械卷轧，切割开口成为一体,密实度比水蒸多层聚乙烯管壳高2倍，保温性能提高10，施工方便,减少人工10，无需错口对结，外观整齐。
产品特点：
防止结露：本材料为闭孔结构，它是靠闭孔内的气体绝热而非聚乙烯材料实现绝热。其具有优异的抗水汽渗透能力。所形成内置的隔汽屏障，即是保温层又是隔汽层，不需另设隔汽层。湿阻因子ц数值远远大于其它保温材料。能有效地避免结露现象发生。
防火性能好：本材料不仅生产普通型而且也生产阻燃型（氧指数≥27）、难燃型（氧指数≥32）两种能满足不同消防要求的高档绝热材料。而且本品在现有的泡沫类保温材料和国内同类产品中烟毒性为最小。
耐候性：本材料由于胶粘度高、稳定性好、紫外线人工照射300小时，表层毫无变化，使用寿命长。
耐腐蚀性：本材料可耐多种化学药品，浸泡后基本不变形，不龟裂，因而可广泛用于化工管道、贮罐的保温。
用途：
用于低温管道保温层厚度为5cm以上，有很好的隔温效果。
施工方法：
1、将保温管壳直接开口套在管道上；
2、用专用胶水沿切割面涂匀，经过几分钟（胶水不粘手时为佳）切面对齐粘合；用扎带扎牢固。
3、外护扎带，【防潮层】在施工中用缠绕方式扎紧即可；
Multi Heat polyethylene insulation shell
Product Description:
Multi-layer heat sealing polyethylene shell, is a mechanical heat sealing in high temperature compression molding, by thermal treatment, mechanical Roll, cut open a whole, than the water vapor density polyethylene shell with high rise 2 times, thermal insulation properties by 10, easy construction, reduce manual 10, no wrong port on the knot, look tidy.
Features:
Prevent condensation: This material is closed cell structure, it is by the gas within the closed cell insulation material rather than polyethylene to achieve insulation. Its excellent resistance to water vapor permeability. Septum formed by the built-in vapor barrier, insulation layer that is vapor layer is separated, without a separate isolation air layer. Wet resistance factor ц value is much larger than other insulation materials. Can effectively prevent condensation phenomenon.
Fire performance is good: not only the production of this material, but also the production of ordinary-type flame retardant (oxygen index ≥ 27), flame retardant type (oxygen index ≥ 32) are two to meet the different requirements of high-grade fire insulation. And the product category in the existing foam insulation materials and similar products in the minimum toxic smoke.
Weather resistance: The material as adhesive, good stability, UV 300 hours of artificial light, no change in the surface, long service life.
Corrosion resistance: The material is resistant to many chemicals, after soaking the basic shape and not cracked, and therefore can be widely used in chemical pipelines, tank insulation.
Uses:
For low-temperature pipe insulation thickness of 5cm or more, a good insulating effect.
Construction method:
1, will direct the opening set of shell and tube heat in the pipeline
2, along the cut surface with a special glue Tu Yun, after a few minutes (when the glue stick better hand) section aligned bonding solid bar with cable ties.
3, outer retaining strap, moisture-proof layer】 【winding way truss construction can be used
