玻化微珠保溫砂漿的防火等級劃分介紹

时间:2016-01-11     作者:華東公司【原创】   阅读

玻化微珠保溫砂漿的防火等級的劃分主要有下面的四大類:標準等級劃分、材料防火等級、參考規定標準以及國際的等級參考。基于近年來建筑用房火宅的不斷發生,人們現在對于保溫砂漿的是否具有防火性能關注的更多,安全有保障的居住環境是消費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)標準等級劃分

(1) the standard hierarchy

很多保溫材料都是易燃物,建筑的外墻保溫材料是預防火災的最薄弱環節,當前國內還未對外墻保溫材料防火等級進行劃分。外墻保溫材料火災發生主要集中在三個階段,一是保溫材料在施工現場的碼放階段,二是保溫材料上墻階段,三是保溫系統施工完畢進入使用階段,在第二、三階段,保溫材料表面或保溫材料之間沒有防火保護層,是火災發生的關鍵時段。

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)材料防火等級

(2) materials fire rating

一般的從材料科學上說就屬巖棉產品是最高了。但是巖棉做外墻保溫存在很多弊端和施工性成本高等問題。礦棉板算是等級最高了。以后國家在制定標準時候會考慮這些問題的。普通磚混結構還是會采用EPS聚苯板為廣泛應用材料。在防火添加劑上會做出嚴格的管理與督察機制。

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)參考規定標準

(3) the reference standard

為了阻止火焰的傳播,一些國家提出采用“防火屏障”的做法,對外墻外保溫系統的防火要求要依據法律、法規和適用于建筑物最終使用的管理條例而定。德國將防火等級分為A-B3級,標準要求聚苯板材料和保溫系統的防火等級應達到B1級,按照EN13501-1標準,聚苯板材料和保溫系統要達到B/C級要求。三是聚苯板外墻外保溫系統中的聚苯板厚度大于10mm時,要在滿足第一個層面的條件下再進行防火構造,達到建筑防火安全規定。構造做法是在每一個窗楣和門楣上口加入不燃高強礦棉防火隔離帶,厚度同聚苯板一致,向上寬度≥200mm;長度方向應比窗口兩側延伸≥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)國際等級參考

(4) refer to the international level

國際上將保溫防火問題分為三個層面:一是在法律法規中明確規定超過22米的建筑嚴禁使用可燃保溫材料,聚苯板外墻外保溫系統只能用于不超過22米的建筑上,高于22米的建筑大部分使用巖棉外墻外保溫系統。二是在歐洲標準ETAG 004,對外墻外保溫系統和保溫材料應按照EN13501-1使用火反應試驗數據分級進行燃燒性能等級A1-E的評定,并規定要標明火焰在保溫材料中傳播的可能性。

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。

特征十分的靠譜:其中有一些十分突出的產品特點就是:雙項絕熱一應用相變添加劑,產生熱熔和熱阻性雙項功能,有別于傳統保溫材料的單一熱阻性。并且,高強抗壓—料體呈網狀結構,與空氣中的二氧化碳,水分反應,在表面生成保護層,形成高抗 壓強度;材料中的羥基可與墻體形成高滲透統一體,其干態粘結力,濕態粘結保值率均優于同類產品,可滿足高層建筑外墻貼面磚的粘結強度要求

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
