GUP decomposed to guanidine polyphosphate GPP(at about 180℃), then to ammonium polyphosphate APP (at about 285℃), and in turn to polyphosphoric acid PPA (at about 385℃). The pyrolysis process of basswood was changed by the treatment of FRW or its components. It was discovered that BZ lose weight at quite lower temperature (165℃) than UZ did, and this may attribute to the catalytic effect of B on the pyrolysis of basswood to form char.
FRW阻燃剂及其组分均改变了木材的热解途径,其中,观察到BZ在较低的温度下(约165℃)即发生明显的失重,说明硼酸的阻燃机理除了传统理论认为的物理覆盖作用以外尚存在化学催化作;GUP 处理使紫椴木材的最大失重速率温度从375℃降低到314℃,同时失重率也显著降低,而成炭率升高;FZ的失重率低于其他处理材。

TG-DSC results revealed that the decomposition of magnetic CoAl HTLcs proceeded in two stages. The first large endothermic effect below 220℃involves the loss of physically absorbed and interlayer water and the second endothermal effect, between 220℃and 402℃, corresponds to the decomposition of the hydroxide layers and the removal of anions in the brucite-like layers. The S_ and pore diameter information of magnetic CoAl HTLcs were tested by N_2 adsorption-desorption analysis.
TG-DSC结果表明磁性CoAl水滑石有两个过程,在220℃以下的第一个失重过程是由于物理吸附水的移除造成的,在220℃至402℃之间的主要失重过程是由于材料脱除结构水,碳酸根离子和部分羟基造成,并伴随着层板结构的塌陷。N_2 adsorption-desorption测试分析了磁性钴铝水滑石的比表面积、孔径等信息。

Firstly the oxidation loss was controlled by the reaction between the coated C/C composites and oxygen. Secondly the oxidation loss was controlled by the producing and vaporing rate of the glass. The oxidation loss was lined with the oxidation time. Thirdly there were cracks in the coating and the deep of the coating was oxidated. The weight loss rate increased linearly and the matrix had been oxidated partly in the end.
