保温资料选用关键介绍

Introduction of insulation data selection

选用时除应考虑资料的导热系数外,还应考虑资料的吸水率、焚烧功能、强度等目标。不同绝热资料的功能特色见相应的分类指南。

In addition to the thermal conductivity of the data, the water absorption, incineration function and intensity of the data should also be taken into account. The functional characteristics of different adiabatic data can be seen in the corresponding classification guide.

无机保温资料一般是指导热系数小于或等于0.2的资料。

Inorganic insulation data are generally used to guide data that the thermal coefficient is less than or equal to 0.2.

在修建和工业中选用杰出的保温技能与资料,往往能起到事半功倍的作用。计算标明,修建中每运用一吨矿藏棉绝热制品,一年可节省一吨石油。北京节能小区选用状况标明,单位面积节煤率每年为11.91公斤标煤/平方米。工业设备与管道的保温,选用杰出的绝热措施与资料,可明显下降出产能耗和本钱,改进环境,一起有较好的经济效益。如:工业设备和管道工程中,杰出的保温条件,可使热量丢失下降95%左右,一般用于保温资料的出资一年左右能够经过节省的能量回收。

The selection of excellent insulation skills and materials in construction and industry can often achieve twice the result with half the effort. The calculation indicates that every ton of mineral wool insulation used in the construction can save a ton of oil a year. The selection of energy saving residential areas in Beijing indicates that the coal saving rate per unit area is 11.91 kilograms per year of standard coal / m2. The insulation of industrial equipments and pipes and the selection of excellent insulation measures and materials can obviously reduce the energy consumption and cost of production, improve the environment and have better economic benefits. For example, in industrial equipment and pipeline engineering, outstanding thermal insulation conditions can reduce heat loss by about 95%. Generally, the investment for thermal insulation materials can be recovered by saving energy in about a year.

A1级防火保温材料

修建资料和修建装饰装饰资料的焚烧功能等级划分

Classification of incineration functions for data and decoration materials

修建资料的焚烧功能是指其焚烧或遇火时所发作的全部物理和化学变化,这项功能由资料外表的着火性和火焰传达性、发热、发烟、炭化、失重,以及毒性生成物的发生等特性来衡量。我国国家标准GB8624-97将修建资料的焚烧功能分为以下几种等级。

The burning function of building materials refers to all the physical and chemical changes that occur when they are burned or caught in fire. This function is measured by the ignition and flame transmission, fever, smoke, carbonization, weightlessness and the occurrence of toxic products. The burning function of the national standard GB8624-97 will be divided into the following grades.

A级:不燃性修建资料:简直不发作焚烧的资料。

Class A: incombustible construction materials: there is no inion about incineration.

B1级:难燃性修建资料:难燃类资料有较好的阻燃作用。其在空气中遇明火或在高温作用下难起火,不易很快发作延伸,且当火源移开后焚烧当即停止。

Class B1: inflammable material: inflammable materials have good flame retardancy. When it meets open fire in the air or under the action of high temperature, it is difficult to ignite, and it is not easy to break out and extend quickly, and when the fire source is removed, the burning stops imtely.

B2级:可燃性修建资料:可燃类资料有必定的阻燃作用。在空气中遇明火或在高温作用下会当即起火焚烧,易导致火灾的延伸,如木柱、木屋架、木梁、木楼梯等。

Class B2: combustible materials: inflammable materials have certain flame retardancy. When exposed to open fire in the air or under the action of high temperature, it will burn imtely, which easily leads to the extension of fire, such as wooden columns, wooden roof trusses, wooden beams, wooden staircases and so on.

B3级:易燃性修建资料:无任何阻燃作用,极易焚烧,火灾危险性很大。

Class B3: inflammable material: no flame retardant, easy to incinerate, and highly dangerous.

不同焚烧功能等级的资料的正确运用

Correct application of inion on different incineration grades

在修建物中运用的建材产品应符合国家强制性标准的要求,这就是GB50222-95《修建内部装饰设计防火标准》,在标准中要求"修建内部装饰设计应妥善处理装饰作用和运用安全的对立,活跃选用不燃性资料和难燃性资料,尽量防止选用在焚烧时发生很多浓烟或有毒气体的资料,做到安全适用,技能先进,经济合理"。因而,顾客在挑选修建资料或者内装饰资料时,在确保装饰质量的一起应优先挑选不燃A级和难燃B1级产品,以保护本身的安全。

Building materials used in buildings should meet the requirements of national mandatory standards, which is GB50222-95 Fire Protection Standard for Building Interior Decoration Design. In the standard, it is required that "the construction interior decoration design should properly handle the opposition between decoration function and application safety, actively select non-combustible and non-combustible materials, and try to prevent them as far as possible." Choose the inion of smoke or poisonous gases that occur during incineration, so as to be safe and applicable, advanced in skills and reasonable in economy. Therefore, when choosing construction materials or interior decoration materials, customers should give priority to non-flammable A-grade and non-flammable B1-grade products in order to protect their own safety.
