石膏板的性能特点：

1.石膏(gao)板重量轻、强(qiang)度能(neng)满足使用要求。石膏(gao)板的(de)厚度一般(ban)为—15mm，每平方米(mi)自重只(zhi)有6—12Kg。用两张纸面石膏(gao)板中间夹(jia)轻钢龙骨就(jiu)是(shi)很好(hao)的(de)隔墙；

2.保(bao)温隔热石膏板纸(zhi)面石膏板板芯60%左右是微小气孔，因空气的导热系数(shu)很小，因此具有良好的轻质(zhi)保(bao)温性能。收缩小。化学(xue)物理性能稳定，干燥(zao)吸湿过(guo)程(cheng)中，伸缩率较小，有效克服了目前(qian)国内其它(ta)轻质(zhi)板材在使用(yong)过(guo)程(cheng)中由(you)于自身伸缩较大而引起接缝开裂(lie)的缺陷。并(bing)且(qie)由(you)于其本身构造的原因可(ke)以轻易的设(she)置变形缝，因此可(ke)用(yong)于容易发生(sheng)轻微位(wei)移(yi)或轻微震动的部位(wei)。

3.防(fang)(fang)火(huo)性(xing)能好石(shi)膏板由于石(shi)膏芯本身不燃，且遇火(huo)时在(zai)释放化合水(shui)的(de)过程(cheng)中会吸收大(da)量的(de)热，延迟周围环境温度的(de)升高，因此，纸(zhi)面(mian)石(shi)膏板具有良好的(de)防(fang)(fang)火(huo)阻燃性(xing)能。经国(guo)家防(fang)(fang)火(huo)检测中心检测，纸(zhi)面(mian)石(shi)膏板隔墙(qiang)耐火(huo)极限可达4小时。
