  • 重量影响挤塑板的性能吗?

对于保温装饰一体板,业内的人几乎都知道,业外的人可能就比较陌生了。不了解保温装饰一体板也没关系,下面,博恩环保就带大家详细了解下。传统的保温隔热材料是以提高气相空隙率,降低导热系数和传导系数为主。纤维类保温材料在使用环境中要使对流传热和辐射传热升高,必须要有较厚的覆层;而型材类无机保温材料要进行拼装施工,存在接缝多、有损美观、防水性差、使用寿命短等缺陷。为此,人们一直在寻求与研究一种能大大提高保温材料隔热反射性能的新型材料


上世纪90年代,美国国家航空航天局(NASA)的科研人员为解决航天飞行器传热控制问题而研发采用的一种新型太空绝热反射瓷层(Therma-Cover),该材料是由一些悬浮于惰性乳胶中的微小陶瓷颗粒构成的,它具有高反射率、高辐射率、低导热系数、低蓄热系数等热工性能,具有卓越的隔热反射功能。这种高科技材料在国外由航天领域推广应用到民,用于建筑和工业设施中,并已出口到我国,用于一些大型工业设施中。但美中不足的是,该材料20美元/kg的昂贵售价实在令国内许多行业望物兴叹,难以承受。由此,国内悄然掀起一股研发隔热保温新材料的热潮,且已率先在国内同行中研制成功具有高效、薄层、隔热节能、装饰防水于一体的新型太空反射绝热涂料。


该涂料选用了具有优异耐热、耐候性、耐腐蚀和防水性能的硅丙乳液和水性氟碳乳液为成膜物质,采用被誉为空间时代材料的极细中空陶瓷颗粒为填料,由中空陶粒多组合排列制得的涂膜构成的,它对400~1800nm范围的可见光和近红外区的太阳热进行高反射,同时在涂膜中引入导热系数极低的空气微孔层来隔绝热能的传递。这样通过强化反射太阳热和对流传递的显著阻抗性,能有效地降低辐射传热和对流传热,从而降低物体表面的热平衡温度,可使屋面温度最高降低20℃,室内温度降低5~10℃。产品绝热等级达到R-33.3, 热反射率为89%,导热系数为0.030W/m.K。监理单位是否按照规定履行监理职责,严格审查外墙保温专业承包单位的资质证书及专业分包合同,严格执行材料进场验收及见证取样制度,是否按规范要求对外墙保温施工过程实施巡视、旁站等监理。

For the insulation decoration board, almost everyone in the industry knows that people outside the industry may be relatively unfamiliar. Do not understand the heat insulation decoration board also does not matter, below, Boen environmental protection with everyone to understand in detail. The traditional heat insulation materials are mainly to increase the voids of the gas phase and reduce the thermal conductivity and conduction coefficient. In order to increase heat transfer and radiation heat transfer in the application environment, the fiber insulation material must have a thick overlay; The type of inorganic insulation materials to be assembled construction, there are many joints, damage to beauty, poor waterproof, short service life and other defects. For this reason, people have been seeking and studying a new kind of material that can greatly improve the thermal insulation reflection performance of thermal insulation materials.
In the 1990s, NASA researchers developed and used a new space adiabatic reflective porcelain layer(Therma-Cover) to solve the problem of heat transfer control of space vehicles. The material consists of tiny ceramic particles suspended in inert latex. It has high reflectivity, high emissivity, low thermal conductivity, low heat storage coefficient and other thermal properties, and has excellent thermal insulation reflection function. This high-tech material has been widely used in the space industry abroad for construction and industrial facilities, and has been exported to China for use in some large industrial facilities. But the snag is that the high price of $20 / kg of the material has made many industries in the country sigh and can not afford it. As a result, the domestic quietly set off an upsurge of research and development of new heat insulation materials, and has taken the lead in the domestic counterparts to develop a new type of space reflection insulation coating with high efficiency, thin layer, heat insulation, energy conservation, and decorative waterproofing.

The coating uses Silicon propyl emulsion and waterborne carbon emulsion with excellent heat resistance, weather resistance, corrosion resistance and waterproof properties as film forming materials, and uses extremely fine hollow ceramic particles known as space age materials as fillers. Consisting of a multi-arranged coating made of hollow ceramic grains, it reflects high solar heat in the visible and near-infrared regions of the 400-1800 nm range, and introduces an air microporous layer with a very low thermal conductivity into the coating to isolate heat energy. Transfer. In this way, by strengthening the obvious resistance to reflection of solar heat and flow transfer, it can effectively reduce radiation heat transfer and heat transfer, thereby reducing the thermal equilibrium temperature on the surface of the object, which can reduce the roof temperature by a maximum of 20 °C and the indoor temperature by 5 ~ 10 °C. The product insulation level reached R-33.3, the thermal reflectivity was 89 %, and the thermal conductivity was 0.030 W/m. K. Whether the supervision unit performs the supervision duties according to the regulations, strictly reviews the qualification certificates and professional sub-contracts of the external wall insulation professional contracting units, strictly implements the material entry acceptance and witness sampling system, and carries out inspections and side stations for the construction of external wall insulation in accordance with the requirements of the regulations.
