建筑保溫材料就像建筑物的“外套”

夏防曬、冬御寒

不僅讓建筑里的人住得更舒服

還能夠延長建筑壽命

可若是大量采用了

可燃的保溫材料

火災(zāi)發(fā)生時墻體會發(fā)生立體燃燒

從而造成重大人員傷亡和經(jīng)濟(jì)損失

實驗看對比!別讓建筑“保溫衣”成為“助燃劑”!

近日

消防救援部門

開展了一場

建筑保溫材料實驗

選取了3種常見的保溫材料

擠塑板、干掛巖棉板、聚氨酯

進(jìn)行劣質(zhì)與合格材料的對比實驗

劣質(zhì)的擠塑板VS合格的擠塑板

消防員使用噴huoqiang分別對

劣質(zhì)及合格的擠塑板

進(jìn)行點火燃燒

劣質(zhì)的擠塑板

遇明火后出現(xiàn)持續(xù)性燃燒

26秒后被火燒穿

不斷有帶明火的泡沫熔化物滴落

實驗看對比!別讓建筑“保溫衣”成為“助燃劑”!

合格的擠塑板

遇明火后邊緣部分慢慢變焦黑

且伴有少量黑煙

huoqiang火焰熄滅后

合格的擠塑板沒有繼續(xù)燃燒

且在相同的時間下沒有被燒穿

實驗看對比!別讓建筑“保溫衣”成為“助燃劑”!

02

劣質(zhì)的巖棉VS合格的巖棉、合格的隔斷層巖棉

消防員用噴huoqiang

三塊不同材質(zhì)的巖棉

進(jìn)行點火燃燒

劣質(zhì)的巖棉

遇明火后出現(xiàn)了分解燃燒

僅24秒被火燒穿

實驗看對比!別讓建筑“保溫衣”成為“助燃劑”!

合格的巖棉

遇明火后

表面部分出現(xiàn)局部碳化

持續(xù)燃燒1分鐘后

沒有被燒穿

實驗看對比!別讓建筑“保溫衣”成為“助燃劑”!

合格的隔斷層巖棉

在持續(xù)1分鐘的明火燃燒后

僅表面部分出現(xiàn)碳化

沒有被燒穿

實驗看對比!別讓建筑“保溫衣”成為“助燃劑”!

↓燃燒后對比↓

03

B2級聚氨酯VSB1級聚氨酯

冷庫中常常使用到聚氨酯保溫材料

消防員用噴huoqiang對

B1級和B2級的聚氨酯保溫材料

進(jìn)行點火燃燒

B2級聚氨酯保溫材料

遇明火后出現(xiàn)了

持續(xù)性燃燒

表面逐漸碳化熔解

實驗看對比!別讓建筑“保溫衣”成為“助燃劑”!

B1級聚氨酯保溫材料

遇明火后表面被熏黑

部分出現(xiàn)碳化

沒有出現(xiàn)脫落破損

和嚴(yán)重熔解的現(xiàn)象

huoqiang火焰熄滅后

沒有發(fā)生持續(xù)性燃燒

實驗看對比!別讓建筑“保溫衣”成為“助燃劑”!

↓燃燒后對比↓

保溫材料起火的相關(guān)案例

1

湖南長沙

2022年9月16日,湖南長沙的中國電信大廈發(fā)生火災(zāi),未造成人員傷亡,火災(zāi)原因為未熄滅的煙頭引燃室外平臺可燃物,進(jìn)而引燃建筑外墻裝飾鋁塑板引發(fā)火災(zāi)。

遼寧沈陽

2019年12月,遼寧沈陽渾南新區(qū)SR國際新城住宅區(qū)發(fā)生火災(zāi),系外墻保溫材料起火,起火建筑共25層,起火部位為5樓及以上外墻。

如何防范建筑“保溫衣”

變成“引火索”?

一起聽聽阿消怎么說

一分價錢一分貨!

大家在購買材料時

一定要購買合格產(chǎn)品
