石膏板的性能特点：

1.石膏(gao)(gao)板重量轻(qing)、强度能满(man)足使用要(yao)求。石膏(gao)(gao)板的厚度一般为—15mm，每平方米(mi)自重只有(you)6—12Kg。用两(liang)张纸面(mian)石膏(gao)(gao)板中(zhong)间夹轻(qing)钢龙骨就是很好的隔(ge)墙；

2.保温(wen)隔热石膏板(ban)(ban)(ban)纸面石膏板(ban)(ban)(ban)板(ban)(ban)(ban)芯60%左右(you)是微小气(qi)孔，因(yin)空(kong)气(qi)的(de)(de)导热系数很小，因(yin)此(ci)具有良好(hao)的(de)(de)轻(qing)质保温(wen)性能(neng)。收缩小。化(hua)学物理性能(neng)稳定，干燥吸(xi)湿过(guo)程(cheng)中(zhong)，伸(shen)缩率(lv)较小，有效克服(fu)了目前国(guo)内其它轻(qing)质板(ban)(ban)(ban)材在(zai)使用(yong)过(guo)程(cheng)中(zhong)由(you)于自身(shen)伸(shen)缩较大而引起(qi)接(jie)缝(feng)开裂的(de)(de)缺陷。并且(qie)由(you)于其本身(shen)构造(zao)的(de)(de)原因(yin)可(ke)以轻(qing)易(yi)的(de)(de)设置变(bian)形缝(feng)，因(yin)此(ci)可(ke)用(yong)于容易(yi)发生轻(qing)微位(wei)(wei)移或轻(qing)微震动(dong)的(de)(de)部位(wei)(wei)。

3.防火(huo)(huo)性能好石(shi)(shi)膏(gao)板(ban)由于石(shi)(shi)膏(gao)芯本身(shen)不燃(ran)，且遇火(huo)(huo)时(shi)(shi)在释放(fang)化合水(shui)的(de)过程(cheng)中会吸收(shou)大量的(de)热(re)，延迟周围环境温(wen)度的(de)升高，因此，纸面石(shi)(shi)膏(gao)板(ban)具有良好的(de)防火(huo)(huo)阻燃(ran)性能。经国家防火(huo)(huo)检测中心检测，纸面石(shi)(shi)膏(gao)板(ban)隔墙(qiang)耐(nai)火(huo)(huo)极限可达4小时(shi)(shi)。
