| 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。Multi-layer thermal bonding polyethylene pipe shell, is in mechanical thermal bonding of high-temperature compression molding, the thermoelectric processing, mechanical volume rolling, cutting openings become one, compaction degree than water evaporate multilayer polyethylene pipe shell high 2 times, insulation performance by 10, construction is convenient, reduce artificial 10, without fault mouth to knot, neat appearance. Product features: To prevent condensation: this material is closed pore structure, it is to rely on closed pore within the gas adiabatic rather than polyethylene material achieve adiabatic. It has excellent resistance to water vapor permeability. Formed by the built-in steam barrier, that is, between insulation layer is every steam layer, do not need to another set every steam layer. Moisture resistance than other factor ц numerical insulation materials. Can effectively avoid the knot shows a phenomenon. Fire performance is good: this material not only production routine but also produce flame retardant type (oxygen index p 27) and flame retardant type (oxygen index p 32) two can satisfy different fire requirement of high-grade adiabatic material. And this product in the existing foam class heat insulating materials and domestic products ZhongYan toxicity to a minimum. Weatherproof: this material because of adhesive degree is high, good stability, ultraviolet radiation, surface layer of artificial 300 hours without change and long service life. Corrosion resistance: this material can be resistant to various chemicals, after soaking basic deformation, not cracked, thus can be widely used in chemical pipes, tank insulation. 双语对照查看 |
