玻化微珠保温砂浆的防火等级划分介绍

时间:2016-01-11     作者:华东公司【原创】   阅读

玻化微珠保温砂浆的防火等级的划分主要有下面的四大类:标准等级划分、材料防火等级、参考规定标准以及国际的等级参考。基于近年来建筑用房火宅的不断发生,人们现在对于保温砂浆的是否具有防火性能关注的更多,安全有保障的居住环境是消费者的第一也是最重要的要求:

 vitrified beads insulation mortar fire rating are mainly divided into the following four categories: fire rating standard hierarchy, material reference, reference standard and the international level. Based on building housing fire continuously in recent years, people are now for thermal insulation mortar is more attention on the fire performance, safeguard the living environment is the first and most important requirement of consumers:


(1)标准等级划分

(1) the standard hierarchy

很多保温材料都是易燃物,建筑的外墙保温材料是预防火灾的最薄弱环节,当前国内还未对外墙保温材料防火等级进行划分。外墙保温材料火灾发生主要集中在三个阶段,一是保温材料在施工现场的码放阶段,二是保温材料上墙阶段,三是保温系统施工完毕进入使用阶段,在第二、三阶段,保温材料表面或保温材料之间没有防火保护层,是火灾发生的关键时段。

A lot of heat preservation material is flammable, the construction of exterior wall thermal insulation material is the weakest link in fire prevention, the current domestic haven't external wall thermal insulation material fire rating. Exterior wall thermal insulation material mainly concentrated in three fireStage, it is the heat preservation material in construction site phase pattern, and the second is the wall heat preservation material phase, three is finished, entered the stage of using thermal insulation system, in the second and third phase, heat preservation material surface or no proof between thermal insulation materialFire protection layer, is the key to the fire.


(2)材料防火等级

(2) materials fire rating

一般的从材料科学上说就属岩棉产品是最高了。但是岩棉做外墙保温存在很多弊端和施工性成本高等问题。矿棉板算是等级最高了。以后国家在制定标准时候会考虑这些问题的。普通砖混结构还是会采用EPS聚苯板为广泛应用材料。在防火添加剂上会做出严格的管理与督察机制。

General) belongs to the rock wool products in materials science is the highest. But rock wool do have some disadvantages exterior wall thermal insulation and construction cost is high. Mineral wool board is one of the highest. After the country when setting standards will consider these problems. Ordinary brick structure will use EPS polystyrene board is widely used material. In the fire retardant additives will make strict management and supervision mechanism.


(3)参考规定标准

(3) the reference standard

为了阻止火焰的传播,一些国家提出采用“防火屏障”的做法,对外墙外保温系统的防火要求要依据法律、法规和适用于建筑物最终使用的管理条例而定。德国将防火等级分为A-B3级,标准要求聚苯板材料和保温系统的防火等级应达到B1级,按照EN13501-1标准,聚苯板材料和保温系统要达到B/C级要求。三是聚苯板外墙外保温系统中的聚苯板厚度大于10mm时,要在满足第一个层面的条件下再进行防火构造,达到建筑防火安全规定。构造做法是在每一个窗楣和门楣上口加入不燃高强矿棉防火隔离带,厚度同聚苯板一致,向上宽度≥200mm;长度方向应比窗口两侧延伸≥300mm。

Put forward in order to prevent the spread of flame, some countries adopt the practice of "fire barrier", external wall external thermal insulation system of fire prevention requirements should be based on laws, regulations, and is suitable for the building use regulations and decide in the end. Germany will preventFire into A - level B3, standards of polystyrene material and thermal insulation system of fire rating should achieve B1 level, in accordance with the EN13501-1 standard, polystyrene board materials and insulation systems to meet the requirements of grade B/C. Three is the polystyrene board exterior insulation system of polyphenyl plate thickness is greater than 10 mm, to meet again into the first level conditionsThe line of fire protection construction, building fire safety regulations. Structure is in each window lintel and signage (join non-combustible high mineral wool fire belt, thickness with polystyrene board, a width of 200 mm or more upward; Length direction should beStretch 300 mm or more than the window.


(4)国际等级参考

(4) refer to the international level

国际上将保温防火问题分为三个层面:一是在法律法规中明确规定超过22米的建筑严禁使用可燃保温材料,聚苯板外墙外保温系统只能用于不超过22米的建筑上,高于22米的建筑大部分使用岩棉外墙外保温系统。二是在欧洲标准ETAG 004,对外墙外保温系统和保温材料应按照EN13501-1使用火反应试验数据分级进行燃烧性能等级A1-E的评定,并规定要标明火焰在保温材料中传播的可能性。

International general insulation fire problem is divided into three levels: one is explicitly stipulated in the laws and regulations more than 22 m building combustible insulation material is strictly prohibited, polystyrene board exterior insulation system can only be used for no more than 22 meters of architecture22 meters, higher than most of the building with rock wool exterior insulation system. Second, in Europe the ETAG 004, external wall insulation system and thermal insulation material shall be in accordance with the EN13501-1 for combustion performance using fire response test data classification level A1 - E evaluation, and to indicate the possibility of flame spread in the thermal insulation material.

玻化微珠保温砂浆这类产品的功能

The function of vitrified beads insulation mortar this kind of product

特征十分的靠谱:其中有一些十分突出的产品特点就是:双项绝热一应用相变添加剂,产生热熔和热阻性双项功能,有别于传统保温材料的单一热阻性。并且,高强抗压—料体呈网状结构,与空气中的二氧化碳,水分反应,在表面生成保护层,形成高抗 压强度;材料中的羟基可与墙体形成高渗透统一体,其干态粘结力,湿态粘结保值率均优于同类产品,可满足高层建筑外墙贴面砖的粘结强度要求

Feature is on, there are some products is very outstanding characteristic is: "a adiabatic application transformation additive, to produce hot melt double function, and the thermal resistance is different from the traditional single thermal resistance of thermal insulation material. And, high-strength compressive - the material body net-like structure, and carbon dioxide from the air, water, generated in the surface layer, the formation of high compressive strength; Material hydroxyl and wall body can be formed in the high permeability continuum, dry state bond, wet bonding resale value is superior to similar products, can satisfy the requirement of the high-rise building exterior wall tile adhesive strength
