今年3月,广东省质监局日前通报2011年广东省消防产品监督抽查结果,其中防火门产品抽样批次合格率仅为44%,可见目前防火门市场的表现难以让人满意。质监局在通报中还指出,耐火完整性不合格的主要原因有四点,一是缝隙处理不恰当。相当一部分防火门配合间隙较大。二是门扇和门框结构设计不合理。门扇和门框的变形率不同,从而造成门扇和门框间的缝隙随着试验时间的延长而越来越大。三是对于木质防火门,木材未经过阻燃处理。四是对于镶玻璃或有亮窗(装修效果图)的防火门,防火玻璃的耐火性能也有影响。
正确的解决办法:应先查看原因。如果是因活页松动导致门扇下沉,应将松动的活页用螺丝固定紧即可。若是门框变形或其原因导致不可恢复的,可从门框入手,将锁舌相应扩充,这样,门锁开关门就可以恢复正常流畅了。二、不要随便使用润滑剂有些朋友们在门锁出现发涩、或发紧的时候,往往喜欢向锁眼里滴上一些润滑油,这样,可能立马门锁通体就顺滑了,但因为油易黏灰,以后锁眼里会容易慢慢积存灰尘,而形成油腻子,奥腾冷弯机械,防火门框滚压机,华夏玻璃网,潍坊奥腾冷弯机械有限公司,这样反而使得门锁更容易出现故障了。正确的解决办法:削一些铅笔碎末或一些蜡烛碎末,通过细管吹入锁芯内部,然后插入钥匙反复转动数次即可。
已提前加冕的恒大显然要尽可能地打好主场收官战。恒大本赛季中超主场战绩13胜1平,是唯一一支主场不败的球队;恒大俱乐部高层近日传出的任免消息再次表明了球队严格管理的态度,这场比赛还可以理解为斯科拉里时代的谢幕战,“卡纳瓦罗将回归恒大”的传言也进一步提升了本场比赛的看点。排名积分榜第4位的权健仅落后华夏幸福1分,奥腾冷弯机械,防火门框滚压机,华夏玻璃网,潍坊奥腾冷弯机械有限公司,理论上还有机会直通亚冠,但谋求攻克恒大主场的难度极大,权健本赛季客场战绩4胜5平5负、客场打入13球失16球等数据进一步表明了争胜难度。本赛季首回合较量权健4-3战胜恒大,权健不仅在该场终结了恒大10连胜,比赛中双方形成入球大战且多次击中球门门框的精彩对峙令人印象深刻。
门框成型机又称门框成型设备、门框冷弯设备、门框加工设备、门框生产设备等,属于国内非标类专用设备,主要应用于各门企来制作各种类型或是版型的门框,是指将金属薄板通过不同的轧辊磨具滚压成型至不同形状的门框型材,一般来说,一个门企往往有很多种的门框类型,所需的门框成型设备也不少,并且生产量也比较大,对设备的要求也比较高,潍坊奥腾冷弯机械有限公司专业研发、制造冷弯设备近20年,有着丰富的制造经验,门框成型机的制造技术成熟稳定,也受到了国内客户的一直好评。
