Recently, Fushun Petrochemical's styrene butadiene rubber plant completed the industrial trial production of the phosphorus-free polymer formulation of the SBR1502 brand product, and the physical properties of the product were tested to be qualified
.
The company's two main brands of styrene butadiene rubber products have completed the phosphorus-free industrial trial production, realizing zero discharge of phosphorus in sewage from the source
The new phosphorus-free production technology of styrene-butadiene rubber was pioneered by Fushun Petrochemical.
On the basis of maintaining the original production formula, through the exploration of the initiator and electrolyte-centric polymerization system, the phosphorus-containing polymerization system was changed to a phosphorus-free polymerization system
.
The rubber production process is special, involving product formulations and additives.
There are as many as 28 kinds of additives such as emulsifiers, activators, and oxidizers.
There are more than 300 process indicators and it is very difficult to change the polymerization system
.
In the absence of samples for reference, the company carried out industrial technology research for the phosphorus-free preparation of styrene-butadiene rubber devices.
Fushun Petrochemical organized the technical force of the styrene-butadiene rubber workshop to conduct non-phosphorus industrial trial production on the No.
4 production line
.
During the trial production, the company increased the frequency of degassed latex Mooney and TSC analysis and comparison, optimized and adjusted the reduction reaction system, the number of reactors, and the amount of regulators added, and strictly controlled the latex blending, agglomeration, extrusion and air delivery.
