Property and application of high performance composite briquette binder

In order to improve water resistance,strength of briquette and decrease its ash,taking organic material as a raw material and dropping strength as reference index,the influence of ratio of binder,NaOH addition amount,reaction time and carbonization temperature etc. on properties of briquette binder was studied. The optimum proportion of the binder and production process conditions of the briquette were determined. The corrosion of the binder to equipment was analyzed. The results showed that the mass ratio of yellow dextrin,PAM,CMC,corn starch and PVA was 1. 0∶ 1. 25∶ 0. 75∶ 2. 0∶ 5. 0. The optimal addition amount of alkali was 0. 26% when the braised time was 2 h. Total moisture content should be controlled at around 15% in the briquette,and the optimum temperature of carbonization was700 ℃. The briquette strength under this condition met industrial production requirement. The ultimate binder had little effects on the asphalt lacquer coating and metal equipment.
