山东挤塑板的导热性能介绍

xps挤塑板的另一重要性能是导热系数,通常将导热系数小于0.232W/ (m·K) 的材料称为保温材料,将小于0.058W/(m·K)的材料称为新型保温材料。近年来,出现了一些新型保温涂料,如以石棉为基材的石棉涂料,其形态为一种微孔网状结构的粘稠糊状物。
Another important property of XPS Extrusion board is thermal conductivity, usually thermal conductivity is less than k, 0.232W/ (m) of materials known as thermal insulation material, will be less than k, 0.058W/ (m) material is a new type of insulation material. In recent years, there have been some new thermal insulation coatings, such as asbestos coating, which is a kind of thick paste with micro porous network structure.
它采用无机和有机材料结合,纤维和颗粒物结合,保温材料生产工艺和涂料生产工艺相结合的方法,从而具有良好的综合效果,使用时可象刷添或涂灰浆一样,将涂料抹在待保温的设备和管道上,干燥之后,再经表面处理,使之具有一定强度,防水,弹性,光滑平整的保温层,设备转动和震动的部位均不会脱落。

It uses a combination of inorganic and organic materials, combined with fiber and particulate matter, a combination of thermal insulation materials production process and coating production process method, which has good comprehensive effect, use can be like Tim brush or coated with mortar, paint rubbed on the equipment and pipelines to be insulated, after drying, after surface treatment to have a certain strength, waterproof, elastic, smooth heat preservation layer, equipment rotation and the vibration of the site cannot fall off.

烧失量能直接反映出制品中石棉纤维的含量,间接反映出制品中所使用石棉纤维的级别,挤塑板能表示制品的内在质量,以及制品选用温度等等。挤塑板绝热包括保温及保冷两大类型,石棉及其很多制品是良好的绝热材料,但习惯上仍称为石棉保温制品。石棉保温制品通常以纱、线、绳、布、纸、毡、粉、管等形式作热力设备、热工管道的保温材料,用于降低设备和管道等的热能损失,延长设备中特定温度的恒定时间。
Burning loss amount directly reflect the content of asbestos fibers in products and indirectly reflects the level of asbestos fibers used products, plastic extruded board can represent the product intrinsic quality, and product selection of temperature and so on. Extruded insulation board comprises a thermal insulation and cold two types, asbestos and a lot of products is of good insulation materials, but habit still called for asbestos insulation products. Asbestos insulation products are usually in the form of yarn, thread, rope, cloth, paper, felt, powder, and other for thermal equipment, thermal pipe insulation materials for reducing equipment and pipeline heat loss, to extend the time constant of equipment in a specific temperature.
石棉纤维的导热系数比多数纺织材料 (天然的或合成的)高,但工业上仍将石棉制品作为保温材料,主要是石棉纤维不自燃,耐温度较高,其次是挤塑板纤维经纺、编、织之后制成石棉纺织制品,其导热系数显著降低,优于其他纺织材料。石棉保温制品在高温下的灼烧失量是一项重要的技术指标,我国一般将制品分为五个等级,用以表示制品的适用温度范围。
Asbestos fiber thermal conductivity than the majority of textile materials (natural or synthetic) high, but industry will still asbestos products as insulation materials, mainly asbestos fiber is not spontaneous combustion, high temperature resistance, followed by plastic extruded board fiber through spinning, weaving, fabric after made of asbestos textile products, the coefficient of thermal conductivity decreased significantly outperforms other textile materials. Asbestos insulation products at high temperature burning loss is an important technical index, China generally products are divided into five grades, to applicable temperature range of said products.
