Flame Retardant Properties

This paper has studied the structure and flame-retardant properties of flame-retardant cellulose fiber with DDPSN as flame retardant. The flame retardants was uniformly dispersed in the cellulose /[Amim]Cl Solution to obtain the good spinnable dope, then the dope was wet-spun. Effects of the flame-retardant contention the fiber structure and properties were investigated. The surface of the flame-retardant cellulose fiber was observed using field emission scanning electron microscope (FESEM). Besides, through the Simultaneous thermal analysis, it has been shown that, with the increase of fame retardant, the degree of fame resistance was obviously improved. The flame retardant acted greatly in condensed phase during the fiber degradation and remained mainly in residues after degradation, the experiments show that the flame-retardant properties of flame-retardant cellulose fiber with 20wt% DDPSN was obvious.

The Relationship

A comparative study on the collecting effect to cassiterite was studied using a new carboxylic acid modified collector DXS and traditional collector salicylaldehyde hydroxamic acid as collectors, respectively. In addition, the relationship between floatability of DXS and crystal structure of cassiterite was investigated. By means of infrared spectroscopy analysis of the cassiterite surface before and after adsorbing DXS molecules, the adsorption mechanisms of DXS on the surface of cassiterite were analyzed.Keywords: carboxylic acid modified collector DXS; cassiterite; flotation mechanism
