EFFECT OF SULFUR TO ACCELERATOR RATIO ON CROSSLINK
ABSTRACT A new relationship among the sulfur to accelerator (S/A) ratio, the degree of reversion or the net loss of crosslinks at the prolonged cure time, and the tensile strength and crosslink str...

curing with sulfur and sulfur donor systems
Such cure system modifications are accomplished via sulfur donors or high ratios of accelerators to sulfur . These cure systems are sometimes called Sulfurless or low sulfur cure systems . sulfur donors Aside from the sulfur itself, sulfur bearing compounds that liberate sulfur at the vulcanization temperature can be used as vulcanizing agents.

Effects of sulfur vulcanization system on cure
The effects of sulfur to accelerator ratio on the cure characteristics, tensile properties (tensile strength, modulus at 300% strain (M300) and elongation at break), thermal aging, thermal stability and oil resistance were investigated.

Vulcanization & Accelerators
between sulfur and the Rubber Hydrocarbon occurs mainly aC (doublet the C = bonds ) and each crosslink requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C

Characterisation of Crosslinks in Vulcanised Rubbers: From
sulfur ratio, longer cure time increase the mono- and di–sulfidic linkages Sulfidic: Mono & disulfidic crosslinks have better solvent and heat resistance, set resistance, reversion resistance but are generally stiffer, hence lower tensile

Impact of ALKALY, SULPHURE and CHLORINE in Kiln operation
re Impact of ALKALY, SULPHURE and CHLORINE in Kiln operation and clinker quality ? Dear Ted, Could you please , advice about detaled calculation of Molar alkali/Sulfo ratio, As I now we have to calculate this parameter of input raw meal with total sulfur of raw meal and coal ,values from Hot meal are .necessary. . can we calculate this parameter for clinker as well??
