一、制作风管的材料是确保空调洁净度的基本条件:

2、材料选用。洁净空调系统风管一般采用镀锌钢板加工。镀锌钢板应选用优质板,镀锌层标准宜>314g/m2,且应镀层均匀,无起壳,无氧化。吊架、加 固框、连接螺栓、华司、风管法兰、铆钉均应采用镀锌件,法兰垫料应采用有弹性、不产尘、有一定强度的软橡胶或者乳胶海绵,风管的外保温可采用容重32K以 上难燃PE板,以专用胶粘贴,不得使用玻璃棉等纤维制品。

3、材料保管。洁净空调用材料应设立专用仓库,或集中存放。存放处要干净,无污染源,避免潮湿,特别是风阀、风口、消声器等部件更应严密包装存放。洁净空调的材料要缩短仓库存放时间,宜随用随进货。制作风管用的板材应将整件运至现场,避免散件搬运途中引起的污染。

二、把好风管制作关,才能保证系统洁净度。

2、洁净系统风管制作要点:加工后半成品应再次擦洗后进入下道工序,风管下料咬口后应立即组合成型,不宜久放。风管法兰加工要保证法兰平面平整,规格要准确,与风管相配,以保证风管 组合连接时接口密封性好。风管底部不得有横向接缝,并且尽量避免纵向接缝,规格大的风管应尽量以整板制作,尽可能减少加强筋,必须设加强筋的也不得使用压 筋加强和风管内加强筋。风管制作应尽量采用联合角或转角咬口,6级以上的洁净风管不得使用按扣式咬口。咬口处镀锌层损坏的、铆钉孔处以及法兰焊接处的镀锌 层损坏的必须补做防腐。风管接缝翻边裂缝处及铆钉孔四周应涂以硅胶密封。风管翻边必须平整均匀。翻边宽度及铆钉孔,法兰螺孔必须严格按规范要求进行。柔性 短管必须内壁光滑,一般可选用人造革或塑胶,风管检查门垫料要用软性橡胶。
