style="text-indent:25px">行業(yè)內(nèi)市場(chǎng)格局還沒有形成，大企業(yè)、大品牌較少，無全國(guó)品牌。防火門產(chǎn)品的研制、開發(fā)和生產(chǎn)對(duì)保障人民生命財(cái)產(chǎn)的安全起到了積極的作用。中國(guó)防火門市場(chǎng)起步較晚，但發(fā)展迅速。近幾年來，一些歐美企業(yè)積極加入到中國(guó)防火門市場(chǎng)的競(jìng)爭(zhēng)，尤其是歐洲企業(yè)，正在力圖使歐式防火門占有更多的中國(guó)市場(chǎng)。面對(duì)國(guó)際競(jìng)爭(zhēng)者，我們必須正視現(xiàn)狀，一方面要虛心向?qū)κ謱W(xué)習(xí)，另一方面要努力增強(qiáng)自己的實(shí)力。我國(guó)的防火門生產(chǎn)企業(yè)正面臨著巨大的挑戰(zhàn)，誰能在這一挑戰(zhàn)中抓住機(jī)遇，誰將成為市場(chǎng)的成功者。</p><p style="text-indent:25px"><p>防火門的開啟方式是非常重要的，原因：1、寬度不足，疏散人群擁擠在樓道而堵塞：防火門都設(shè)在重要的疏散通道和樓梯出口上，而每棟建筑物的總疏散寬度都是經(jīng)過設(shè)計(jì)計(jì)算決定的，如果防火門開啟角度影響疏散通道的寬度時(shí)，則屬于安全隱患，在規(guī)范中是違規(guī)的。2、門開啟方向錯(cuò)誤，當(dāng)在拉開門時(shí)，后面的疏散人群涌上而把疏散門堵上，并擠壓前面的人群而堵塞，故在現(xiàn)實(shí)行的消防規(guī)范中疏散通道的防火門必須為向疏散方向開啟，即從建筑物室內(nèi)中通向首層、屋面、避難層的路線，門均是順著逃生方向推開的。3、疏散門上鎖，從內(nèi)無法打開。浙江程程消防設(shè)備有限公司致力于提供防火門設(shè)備，歡迎您的來電！</p><div
