Chinas industrialization of biomass briquette fuel prototype is formed, however, to be mature and realize industrialization, you first need to overcome some constraints, some technical obstacles. Includes the main working parts of the short working life, poor ability to coordinate equipment

11、systems, running unstable, and so on. Also, due to the lack of effective industrial practices, solid biomass industry is still in its infancy in China. Biomass fuel shaping technology, stable performance and low power consumption of the device is the core of industrialization of biomass fuel, good i

15、特性2.2.1 无地暖保温垫层构造：2.2.1.1 相对于传统混凝土垫层高热传系数，保温隔热性能优越；2.2.1.2 轻质高强，容重仅为混凝土的十分之一至八分之一，减轻结构自重，节省建筑物主体钢筋以及混凝土用量；2.2.1.3 施工简便，机械化浇灌，节省人工，降低综合成本；2.2.1.4 作为地面垫层使用时抗击声压等级高，隔声效果优异。2.2.2 有地暖保温构造：2.2.2.1 相对于挤塑板，筑粒混凝土抗压强度高，抗冲击性能良好，无需加钢丝网固定地暖管；2.2.2.2 免去混凝土地面垫层施工工序，节省房屋建筑成本；2.2.2.3 与结构基层粘结力高，干燥收缩率小，不会产生空鼓开裂现象；2.2.

16、2.4 整体性好，可进形成连续无接缝保温层,不会因拼缝产生冷热桥现象；2.2.2.5 保温耐久性好，高温时无有害气体产生。传统地暖保温构造 筑粒混凝土地暖保温构造三、施工准备：3.1 主要材料和机具： 3.1.1 水泥：32.5号及其以上普通水泥或复合水泥。 3.1.2 筑粒骨料：平均粒径36mm。3.1.3 其它掺合料：无。3.1.4 主要机具：带预搅拌砂浆喷涂（泵送）机、平锹、小水桶、半截桶、笤帚、2m靠尺、杠尺、木抹子、钢丝刷、凿子、锤子、铁抹子等。3.2 作业条件： 3.2.1 结构工程完成，水电管道已铺设完毕，并经有关部门验收，达到合格标准。3.2.2 将地面外露的钢筋头、铁线等彻底

17、清除，处理点应抹入水泥砂浆，将屋面板上的混凝土、砂浆等污物彻底清理干净，经检查验收合格，方可铺设保温材料。3.2.3 穿过结构的管根部位，应用细石混凝土堵塞密实，以使管子固定。3.2.4 室内墙面已弹好+50cm水平线。四、施工工艺： 找标高、弹控制线基层处理洒水湿润挂线贴灰饼浇筑筑粒混凝土养护4.1 找标高、弹面层水平线：根据已有的水平标高控制线，测出屋面面层厚度的水平控制线，弹在四周女儿墙面上。4.2 基层清理，将屋面结构层表面杂物、灰尘清理干净。4.3 洒水湿润：在施工前一天对基层表面进行洒水湿润。4.4 抹灰饼：通过已弹出的屋面层水平标高控制线，横竖拉线，用筑粒混凝土相同配合比的拌合料

18、做灰饼，横竖间距不超2m。4.5 筑粒混凝土搅拌：先将水泥与水搅拌，然后按设计配比需求加入骨料再一同搅拌均匀；如使用专用机械搅拌每罐搅拌时间不少于2分钟，至灰浆搅拌均匀后即可进行泵送浇筑。4.6 垫层筑粒混凝土铺设：将搅拌好的混凝土铺抹到屋面基层上，紧接着用2m长刮杠刮平即可。五、施工要点：5.1 为了控制筑粒混凝土的厚度，施工前必须做灰饼。5.2 要保证面层层和保温层之间的施工间隔时间，要让保温层稳定后再进行面层的施工。上人过早会使轻质混凝土表面骨料脱落，影响下步工序。5.3 要注意保温层的养护，养护时间必须严格按照施工工艺中提供的养护时间。5.4 施工时如下层已经开始进行顶板装修，建议在轻质混凝土施工前在地面上铺设一层防潮层后再施工，以免灰浆、水分向板下渗漏。5.5 施工温度宜控制在5以上，如低温施工时应采取防冻保护措施。5.6 如使用筑粒混凝土作为轻钢楼面结构板施工时，需按设计要求在混凝土内增设钢筋网片。5.7 由于筑粒轻质混凝土流动性较好，在施工洞口处施工时请在洞口处做10cm宽细石混凝土挡墙，高度同轻质混凝土垫层厚度。5.8 地面垫层施工宜采用3#或
