Description

轻质高强度纸面石膏板及生产工艺
技术领域
本发明涉及石膏板技术领域，具体是轻质高强度纸面石膏板及生产工艺。
背景技术
纸面石膏板是以建筑石膏为主要原料，掺入适量添加剂与纤维做板芯，以特制的板纸为护面，经加工制成的板材。纸面石膏板具有重量轻、隔声、隔热、加工性能强、施工方法简便的特点。
纸面石膏板作为一种新型建筑材料，在性能上有以下特点：
生产能耗低，生产效率高：生产同等单位的纸面石膏板的能耗比水泥节省78％。且投资少生产能力大，工序简单，便于大规模生产。
轻质：用纸面石膏板作隔墙，重量仅为同等厚度砖墙的1/15，砌块墙体的1/10，有利于结构抗震，并可有效减少基础及结构主体造价。
保温隔热：纸面石膏板板芯60％左右是微小气孔，因空气的导热系数很小，因此具有良好的轻质保温性能。
防火性能好：由于石膏芯本身不燃，且遇火时在释放化合水的过程中会吸收大量的热，延迟周围环境温度的升高，因此，纸面石膏板具有良好的防火阻燃性能。经国家防火检测中心检测，纸面石膏板隔墙耐火极限可达4小时。
隔音性能好：采用单一轻质材料，如加气砼、膨胀珍珠岩板等构成的单层墙体其厚度很大时才能满足隔声的要求，而纸面石膏板隔墙具有独特的空腔结构，具有很好的隔声性能。
装饰功能好：纸面石膏板表面平整，板与板之间通过接缝处理形成无缝表面，表面可直接进行装饰。
加工方便，可施工性好：纸面石膏板具有可钉、可刨、可锯、可粘的性能，用于室内装饰，可取得理想的装饰效果，仅需裁制刀便可随意对纸面石膏板进行裁切，施工非常方便，用它做装饰材料可极大的提高施工效率。
舒适的居住功能：由于石膏板的孔隙率较大，并且孔结构分布适当，所以具有较高的透气性能。当室内湿度较高时，可吸湿，而当空气干燥时，又可放出一部分水分，因而对室内湿度起到一定的调节作用，国外将纸面石膏板的这种功能称为“呼吸”功能，正是由于石膏板具有这种独特的“呼吸”性能，可在一定范围内调节室内湿度，使居住条件更舒适。
绿色环保：纸面石膏板采用天然石膏及纸面作为原材料，决不含对人体有害的石棉(绝大多数的硅酸钙类板材及水泥纤维板均采用石棉作为板材的增强材料)。
节省空间：采用纸面石膏板作墙体，墙体厚度最小可达74mm，且可保证墙体的隔音、防火性能。
由于纸面石膏板具有质轻、防火、隔音、保温、隔热、加工性强良好(可刨、可钉、可锯)、施工方便、可拆装性能好，增大使用面积等优点,因此广泛用于各种工业建筑、民用建筑，尤其是在高层建筑中可作为内墙材料和装饰装修材料。如：用于柜架结构中的非承重墙、室内贴面板、吊顶等。
但是，现有纸面石膏板，由于重量轻，室内安装时容易造成安装时发生划痕，裂痕等情况，并且，纸面在环境较为潮湿时，容易造成浸湿导致颜色发生差别，而且纸面受潮后容易发霉，造成室内霉菌污染。
因此，本发明提供了轻质高强度纸面石膏板及生产工艺，以解决上述背景技术中提出的问题。
