Sulfur reddish brown is a sulphur dye. The sulphur dye is a dye to be dissolved in a sulfide base, mainly used for dyeing cotton fibers, and also for cotton/dimensional blended fabrics. The cost is low, and the dyed products are generally washable and light-resistant, but the color is not bright enough. Commonly used varieties are sulfur black, sulfur blue and the like. Soluble sulphur dyes are now available. A dye produced by the sulfurization reaction of an amine, phenol or nitro compound of an aromatic hydrocarbon with sulfur or sodium polysulfide, was first synthesized by the French chemists Crusian and Bretonier.
Vulcanized red brown special dryer Working principle:
The hot air enters the agitating and pulverizing drying chamber from the bottom of the dryer at an appropriate spraying speed by the inlet pipe, and the material is strongly sheared, collided, and rubbed to be micronized, thereby enhancing mass transfer heat transfer.
At the bottom of the dryer, the larger and drier pellets are broken by the device under the action of the agitator. The particles with lower moisture content and smaller particle size are entrained by the swirling gas stream and further dried during the ascending process. Since the gas-solid two phases are rotating, the solid phase inertia is larger than the gas phase, and the relative velocity between the solid and gas phases is large, and the mass transfer heat transfer between the two phases is strengthened, so the machine has high production intensity.
Vulcanized red brown special dryer Features:
1. A variety of feeding devices are available for selection, the feeding is continuous and stable, and no bridging phenomenon occurs in the middle of the process.
2. A special cooling device is installed at the bottom of the dryer to avoid deterioration of the material in the high temperature zone at the bottom.
3. Special air pressure sealing device and bearing cooling device can effectively extend the service life of the transmission part.
4, special air distribution device, reduce the resistance of the equipment, and effectively provide the treatment of the dryer.
5. The drying chamber is equipped with a grading ring and a swirling sheet, and the material fineness and final water content are adjustable. (eg calcium carbonate final water can be adjusted to ≤ 0.1%)
6. Compared with other drying methods, it can effectively increase the specific gravity of materials.
7. The indoor air velocity in the drying chamber is high, and the material residence time is short, which effectively prevents the material from sticking to the wall and the deterioration of the heat sensitive material, achieving high efficiency, rapid, small equipment and large production.
