Description

无甲醛环保型消音弯头 
(一)、技术领域
本实用新型涉及一种专门设计用于空调通风系统管道中,用于衰减通风机或排放烟气产生的噪声,使室内环境噪声符合设计要求,如电视台播录室、音乐厅等,或用于营造安静舒适的工作、生活环境,如办公室、宾馆、商场、车间等的无甲醛环保型消音弯头。 
(二)、背景技术
传统消音弯头使用在管道转弯处消声,在吸声层中的材料采用超细玻璃棉外覆盖镀锌钢丝网,以加固原结构使消声材料不易损坏和被气流吹走。同时外壁均用镀锌钢板制成,弯头的外侧做成直角,内侧具有弯曲的形状,具有阻力小的同时对高、中频有较大的消声作用。 
传统的吸声材料玻璃棉和超细玻璃棉,其粘结剂中含有甲醛,酚醛树脂和尿素等对人体有害的物质,而酚醛树脂极易引起甲醛的挥发,会对人体的健康造成严重的后果。传统的吸声材料玻璃棉和超细玻璃棉,耐用性能弱,不适用于现在对于通风管道系统材质要求越来越高的安静舒适的住宅、商用及工业建筑。 
(三)、实用新型内容
为了解决传统玻璃棉粘结剂中含有对人体有害的物质和传统玻璃棉内表面防火性能差、抗磨损能力低,耐用性能弱的问题,使消声弯头更加环保,本实用新型提供一种无甲醛环保型保温吸音玻璃棉,该实用新型采用无甲醛粘结剂不含甲醛、酚醛树脂、尿素等有害物质,对人体的健康无影响。 
本实用新型无甲醛环保型消音弯头,采用无甲醛环保型保温玻璃棉解决了传统玻璃棉的缺陷和不足之处,更好的被应用于对通风系统要求高的工业建筑行业,对建筑物室内环境质量和居住者的舒适程度做出了重大贡献。 
本实用新型的目的是提供一种专门设计用于空调、通风系统的无甲醛环保型消音弯头,其消音玻璃棉解决彻底消除普通玻璃棉中甲醛污染的技术问题;解决普通玻璃棉内表面防火 性能低、阻力较大的问题。适用于所有运行环境噪声符合设计要求,如电视台播录室、音乐厅等,或用于营造安静舒适的工作、生活环境,如办公室、宾馆、商场、车间等的风管系统,适用于衰减通风机或排放烟气产生的噪声,使室内环境舒适的无甲醛环保型消音弯头。 
本实用新型的技术方案:本实用新型无甲醛环保型消音弯头,采用无甲醛环保型保温消音玻璃棉。该消音棉是由粘结了无甲醛环保型丙烯酸热固性树脂的无机玻璃纤维制造而成,经久耐用,提供可清洁的防火内表面。无甲醛环保型保温消音玻璃棉易于制作安装,其性能稳定可靠,广泛应用于电视台播录室、音乐厅等,或用于营造安静舒适的工作、生活环境,如办公室、宾馆、商场、车间等的风管系统。 
本实用新型与现有传统技术相比具有的有益效果: 
本实用新型无甲醛环保型消音弯头中采用无甲醛环保型保温消音玻璃棉,该消音棉采用无甲醛环保型白色玻璃纤维棉制造而成。无甲醛环保型白色玻璃纤维棉在传统离心玻璃棉基础上,对玻璃纤维棉原料配方和成型工艺做部分调整,使玻璃纤维与无甲醛粘结剂叠粘、固化、成型。无甲醛环保型白色玻璃纤维棉采用的粘结剂与传统玻璃棉完全不同,是一种无甲醛丙烯酸类粘结剂。它彻底抛弃了苯酚、甲醛、尿素等有毒、有害物质,杜绝了普通玻璃棉内管的甲醛污染。本实用新型无甲醛环保型消音弯头,在具有传统消声的作用外,同时具有环保性能,对人体的健康无影响。 
本实用新型具有以下优点: 
(1)改善建筑物室内环境,通过帮助控制温度及声音来改善室内环境质量。 
(2)节约能源。 
(3)消声频带宽,对高、中、低频率噪声均有良好的消声效果。消声效果稳定,使用寿命长,防火、防潮。 
本实用新型无甲醛环保型消音弯头中采用无甲醛环保型保温消音玻璃棉和丙烯酸类粘结剂,抛弃了传统粘结剂中的苯酚、甲醛、尿素等有害物质,不含氨、苯等有害物质,无味无毒,保护人体健康,改善工作环境。无甲醛环保型吸引玻璃棉的纤维细长、棉分布均匀、回弹性好,具有和普通离心玻璃棉同样优异的物理性能和热性能。无甲醛环保型玻璃棉为天然的纯白色,使产品更漂亮、美观。用无甲醛粘结剂生产的低密度离心玻璃纤维棉已通过室内空气质量测试和环境认证。测试结果表明,本产品不会释放污染物质,因而不会对室内环境造成污染。 
(四)附图说明 
图1是本实用新型无甲醛环保型消音弯头的结构示意图。1为镀锌铁皮外套,2为无甲醛环保消音棉,3为穿孔板。图2是本实用新型无甲醛环保型消音弯头的结构示意侧视图。 
(五)具体实施方式
实施例,参见图1图2,本实用新型无甲醛环保型消音弯头,外层为镀锌铁皮,铁皮外套的厚度为0.5mm至1.2mm,消音吸声层采用无甲醛环保型保温消音玻璃棉。 
消音层是低密度离心无甲醛环保玻璃纤维棉,颜色为白色,主要用于吸声消音。离心玻璃纤维棉由无甲醛粘结剂和玻璃纤维叠粘而成。也可以是涂料外加白色短纤维毡;或者采用玻璃纤维布;它具有阻燃、防霉、防潮、粘吸玻璃纤维的功用。 
上述低密度离心玻璃纤维棉中的玻璃纤维平均直径为5-8μm。
