rubber chemicals
Initial alcohol content composition 25-30%
Final alcohol content component 0.5%
In the chemical formula of rubber additives, R 'is H and R is an organic group; Or R 'and R are both organic groups; R 'and R can also form rings from accelerator M or its sodium salt, or accelerator DM, and can be prepared through different processes with cyclohexylamine (product as accelerator CZ), dicyclohexylamine (product as accelerator DZ), diisopropylamine (product as accelerator DIBS), morpholine (product as accelerator NOBS), tert butylamine (product as NS), etc.
Working principle of rubber additive disc continuous dryer:
Wet materials are continuously added to the feeding hopper of the main machine, and are continuously added to the first layer of the drying disc on the upper part of the dryer by a spiral feeder. The rake arm with rake blades rotates to make the rake blades continuously flip the materials, allowing the materials to fully absorb heat. The materials flow along the exponential spiral line on the surface of the drying disc, and the materials on the small drying disc are transferred to the outer edge and fall to the outer edge of the large drying disc below. The materials on the large drying disc move inward and fall into the lower small drying disc from the middle discharge port. The large and small drying discs are alternately arranged up and down, and the materials can continuously flow through the entire dryer. The hollow drying disc is filled with heating medium. The heating medium enters the drying disc from one end and exits from the other end. The dried material falls from the last drying tray to the cooled bottom layer of the shell, and is finally transferred to the discharge port by the rake blade and discharged by the air damper. Moisture evaporates and evaporates from the material, fine powder is recovered by an external dust collector, solvent is condensed and recovered by a condenser, and exhaust gas is discharged outdoors by a dehumidification fan.
Main technical characteristics of rubber additive disc continuous dryer:
1. Low energy consumption: Drying is carried out using conductive heat, which has high thermal efficiency, low transmission power, and low energy consumption;
2. Good working environment and fully compliant exhaust emissions;
3. Easy regulation, strong applicability, uniform drying, and stable quality;
4. Easy to operate and maintain;
5. Easy installation and small footprint;
