大型、展覽綜合樓等如因面積過(guò)大，超過(guò)了防火分區(qū)大允許面積規(guī)定，在采用防火墻作防火分隔時(shí)，不便于經(jīng)營(yíng)和管理，便更多地采用了防火卷簾替代防火墻。那你知道防火卷簾門(mén)耐火極限的測(cè)試方法嗎？下面濟(jì)南防火卷簾門(mén)安裝維修人員為您講解。

If the large area of large shopping malls and exhibition complex buildings exceeds the large allowable area of the fire compartment, and it is not convenient for operation and management to use the firewall as the fire compartment, the fire shutter is more used to replace the firewall. Do you know the test method of fire resistance limit of fire resistant rolling shutter door? Next, Jinan fire shutter door installation and maintenance personnel will explain to you.

實(shí)際上，防火卷簾門(mén)耐火極限的測(cè)試方法有兩種：

In fact, there are two methods to test the fire resistance limit of fire shutter doors:

一是防火卷簾門(mén)按照現(xiàn)行標(biāo)準(zhǔn)進(jìn)行耐火試驗(yàn)，包括背火面溫升在內(nèi)的各項(xiàng)判定條件判定;

First, fire resistance test shall be carried out for fire resistant rolling shutter doors according to the current standards, and the judgment conditions including the temperature rise of the back fire surface shall be determined;

二是同樣按照標(biāo)準(zhǔn)進(jìn)行耐火試驗(yàn)，根據(jù)該標(biāo)準(zhǔn)中關(guān)于無(wú)隔熱保護(hù)層的鐵皮卷簾免測(cè)背火面溫升的規(guī)定和產(chǎn)品標(biāo)準(zhǔn)要求，只以距背火面一定距離的輻射熱強(qiáng)度和簾面是否穿火來(lái)判定卷簾耐火極限的卷簾。

Second, the fire resistance test is also carried out according to the standard. According to the provisions of the standard on the temperature rise of the iron sheet roller shutter without thermal insulation protection layer and the requirements of the product standard, the fire resistance limit of the roller shutter is determined only by the radiant heat intensity at a certain distance from the back fire surface and whether the curtain surface is through fire.

按照不包括背火面溫升作耐火極限判定條件的非隔熱防火卷簾門(mén)，所得耐火極限數(shù)據(jù)，遠(yuǎn)比包括背火面溫升作耐火極限判定條件的隔熱型防火卷簾門(mén)的耐火極限要長(zhǎng)得多。

According to the non-insulated fire shutter door which does not include the temperature rise of the back fire surface as the fire resistance limit judgment condition, the fire resistance limit data obtained is much longer than that of the insulated fire shutter door which includes the temperature rise of the back fire surface as the fire resistance limit judgment condition.

根據(jù)測(cè)試方法將防火卷簾門(mén)劃分為兩類(lèi)，即：普通防火卷簾門(mén)和特級(jí)防火卷簾門(mén)，普通防火卷簾門(mén)不以背火面溫升為判定條件，耐火極限不低于3h時(shí)，能達(dá)到隔熱防火分隔的要求;而特級(jí)防火卷簾門(mén)以背火面溫升為判定條件，當(dāng)耐火極限不低于3h時(shí)，則具有隔熱功能，能達(dá)到防火分區(qū)分隔的要求。

According to the test method, fire shutter doors are divided into two categories, namely, ordinary fire shutter doors and special fire shutter doors. Ordinary fire shutter doors do not take the temperature rise of the back fire surface as the judgment condition, and can meet the requirements of thermal insulation and fire separation when the fire endurance is not less than 3h; The super-grade fireproof rolling shutter door takes the temperature rise of the back fire surface as the judgment condition. When the fire resistance limit is not less than 3h, it has the heat insulation function and can meet the requirements of fire compartment separation.

由于普通防火卷簾門(mén)的隔火作用達(dá)不到防火分區(qū)分隔的要求，若采用這種防火卷簾門(mén)，應(yīng)在卷簾兩側(cè)設(shè)獨(dú)立的閉式自動(dòng)噴水系統(tǒng)或水幕保護(hù)。

Since the fire isolation function of ordinary fire shutter door cannot meet the requirements of fire compartment separation, if this fire shutter door is adopted, independent closed automatic sprinkler system or water curtain protection shall be set on both sides of the shutter.

近年來(lái)，消防產(chǎn)品市場(chǎng)防火卷簾門(mén)生產(chǎn)廠家眾多，有的廠家提供的普通防火卷簾門(mén)耐火極限可達(dá)3h、4h，根據(jù)廠家提供的數(shù)據(jù)及有關(guān)部門(mén)檢測(cè)報(bào)告，一些設(shè)計(jì)者由于不清楚防火卷簾門(mén)的測(cè)試方法，誤以為防火卷簾門(mén)耐火極限可達(dá)3h、4h就可不設(shè)保護(hù)設(shè)施直接設(shè)防火分區(qū)上。

In recent years, there are many manufacturers of fire rolling shutter doors in the fire protection product market. Some manufacturers provide common fire rolling shutter doors with a fire resistance limit of 3h and 4h. According to the data provided by the manufacturer and the test report of the relevant national departments, some designers mistakenly believe that the fire resistance limit of fire rolling shutter doors can reach 3h and 4h, so they can be directly set on the fire compartment without protective facilities.

而特級(jí)防火卷簾門(mén)如雙軌雙簾無(wú)機(jī)復(fù)合防火卷簾門(mén)、蒸發(fā)式汽霧式防火卷簾門(mén)，其卷簾結(jié)構(gòu)進(jìn)行了特殊處理，按包括以背火面溫升為判定條件進(jìn)行測(cè)試且耐火極限能達(dá)到3h以上，可達(dá)到防火墻耐火極限要求。因此，對(duì)采用特級(jí)防火卷簾門(mén)就不必要再采用自動(dòng)噴水系統(tǒng)保護(hù)。還有什么事項(xiàng)就來(lái)我們網(wǎng)站http://luoboyy.com咨詢(xún)吧！

The special fireproof rolling shutter door, such as double-track double-curtain inorganic composite fireproof rolling shutter door and evaporative vapor fog type fireproof rolling shutter door, has been specially treated in its rolling shutter structure, and tested according to the judgment conditions including the temperature rise of the back fire surface, and the fire resistance limit can reach more than 3h, which can meet the fire resistance limit requirements of the firewall. Therefore, it is unnecessary to use automatic water spray system for the protection of super-grade fireproof rolling shutter doors. Come to our website for any other matters http://luoboyy.com Ask!
