        The PU material used in exterior insulation in fire accident Nov 15th

        根據(jù)媒體報(bào)道的“11.15”上海膠州路大樓火災(zāi)的外墻保溫工程涉及聚氨酯材料，就相關(guān)情況，記者連線中國(guó)聚氨酯工業(yè)協(xié)會(huì)副秘書(shū)長(zhǎng)李建波先生，了解相關(guān)情況。
        As per media report, PU material is involved in the exterior insulation project in the fire accident Nov 15th, the journalist contacted the deputy chainman of CPUIA, Mr. Li JianBo for the detailed.

        據(jù)李秘書(shū)長(zhǎng)介紹，失事大樓的外墻保溫采用的是硬泡聚氨酯噴涂薄抹灰結(jié)合EPS板薄抹灰保溫系統(tǒng)，其中硬泡聚氨酯噴涂薄抹灰主要用于大樓主體，EPS板薄抹灰用于建筑陽(yáng)角和窗口部位。施工步驟主要是，基層墻體處理  硬泡聚氨酯噴涂  砂漿找平  抗裂砂漿粘貼網(wǎng)格布  外飾面施工。從相關(guān)新聞報(bào)道得知，大樓硬泡聚氨酯噴涂保溫工程只是施工到12層左右，其中10層以下已經(jīng)進(jìn)行了砂漿找平。
        According to Mr. Li, the exterior insulation used for this building is rigid PU foam thin plaster with EPS panel thin plaster system, with the former mainly used for the main building, and the latter for the corner and window area. The main construction procedure is, basic wall preparation, PU rigid foam spray, mortar leveling, anti-crack mortar plus fishnet clothing, exterior decorating. As reported, the rigid foam had just been constructed to around 12th floor, and the floors lower than 10 have gone through the step of mortar leveling.

        按照我國(guó)建筑外墻保溫的相關(guān)標(biāo)準(zhǔn)要求，用于建筑節(jié)能工程的保溫材料本身是不會(huì)被電焊火花引燃的。根據(jù)上海市消防局局長(zhǎng)的介紹，火災(zāi)是違規(guī)焊接引燃了建筑外的可燃易燃尼龍網(wǎng)，又引燃了腳手架上的可燃的竹片踏腳板，同時(shí)事故現(xiàn)場(chǎng)風(fēng)力較大，導(dǎo)致火勢(shì)順著尼龍網(wǎng)和腳踏板快速蔓延，最終引燃了部分泡沫材料和建筑物室內(nèi)的家具和裝修物資等，特別是室內(nèi)的電線、煤氣管道等在大火下造成了火焰在室內(nèi)的傳播，最終導(dǎo)致了嚴(yán)重的損失。
        According to related exterior insulation codes, the qualified insulation material itself will be not be ignited by the welding sparkles.  As per introduction of director of Shanghai Fire Fighting Bureau, the fire was initiated by the nylon safe net ignited by unauthorized welding, then it spread to the combustible bamboo plate on the scaffolding, with help of strong wind, spreading very quickly then finally ignited some foam material and interior furniture and decoration material and so on, especially via the interior electrical wires, gas tubes spreading into the rooms, and finally caused severe damage.

        從燃燒后大樓情況看，進(jìn)行了聚氨酯外墻保溫的12層以下部分，特別是進(jìn)行了砂漿找平處理的區(qū)域，保溫層基本完好，甚至沒(méi)有出現(xiàn)過(guò)火現(xiàn)象，并沒(méi)有助長(zhǎng)火勢(shì)蔓延；而沒(méi)有進(jìn)行聚氨酯保溫的12層以上部分，其火勢(shì)的蔓延完全是易燃尼龍網(wǎng)和竹片踏腳板造成的。
        From the picture of the building taken after the fire, the building exterior wall lower than 12 floor which has been insulted, especially those mortar leveled, the insulation was almost not impacted, even no sign of burning, it is obvious that it did not contribute the fire; and the upper part the fire entirely caused by combustible safe net and bamboo plates.

        李秘書(shū)長(zhǎng)最后表示，國(guó)內(nèi)絕大部分建筑外保溫火災(zāi)是發(fā)生在施工階段。面對(duì)這樣的情況，建議一方面要保證建筑保溫施工的材料滿足相關(guān)標(biāo)準(zhǔn)規(guī)范要求，更重要的是要加強(qiáng)建筑工地的消防安全管理，加強(qiáng)安全施工技能培訓(xùn)，加快出臺(tái)相關(guān)管理規(guī)范和制度，并嚴(yán)格落實(shí)執(zhí)行。
        Mr. Li stated that most of fire accidents related to exterior insulation in China occurred at construction period. Considering this fact, he recommends we should ensure the material has to be fulfill related codes and standards, more importantly, improve the construction safety management, enhance the construction skill & safe training, facilitate the developing of corresponding regulations and put into strict implementation.
