Rubber accelerator, antioxidant dedicated rotary film evaporator
Detailed description
Rubber accelerator, antioxidant dedicated rotary film evaporator
project description:
Rubber accelerator refers to rubber vulcanization
accelerator. Sulfur vulcanized rubber is mainly used to carry out, but
the reaction of sulfur with the rubber is very slow, so the
vulcanization accelerator emerged. Promoting agent is added rubber
compound can induce curing agent activation, thereby accelerating the
crosslinking reaction curing agent with the rubber molecules, to shorten
the curing time and reduce the curing temperature effect.

accelerator is mainly used by the chemical structure of the main points
are sulfenamides, thiazoles, thiurams, there are some guanidines,
thioureas and dithiocarbamate salts. Wherein the sulfenamide best
overall performance, the most widely used.
Means capable of preventing or inhibiting antioxidant such as oxygen, heat, light, ozone, mechanical stress, heavy metal ions on the performance of damaged products, and to extend the storage life of the product ingredients. Reduce the phenomenon is called aging. With the conduct and development of rubber products and performance of the aging process that will gradually reduce the total loss of value.

Equipment summary:
GXZ series of highly efficient rotary film evaporator, the
scraper evaporator, a forced deposition by rotating blades, new high
efficiency evaporator can be a falling film evaporator under vacuum
conditions, it is the heat transfer coefficient, high evaporation
strength, overcurrent short time, operating flexibility, especially
suitable for heat-sensitive materials shall, high viscosity materials
and concentrated by evaporation and crystallization containing
particulate material, removing solvent degassing, distillation
purification. Our company has been manufacturing such equipment for many
years, and accumulated a wealth of manufacturing experience. For a long
time customer closely actual production and market demand, to meet user
process requirements, select the appropriate and reasonable structure,
reliable manufacturing ensure high quality, tooling equipment, testing
methods and product design and other aspects of continuous improvement
and increasingly perfect, has made a remarkable achievement, technical
level and product quality in the domestic leading level.
working principle:
working principle:
Material enters the heating zone from the top of the radial
evaporator, distributed through distributor to the evaporator heating
wall, then rotate the wiper rolling the material is uniformly heated
surface continuously scraped into a uniform thickness of the liquid
film, and the downward spiral advance. In this process, the rotation of
the wiper rolling to ensure continuous and uniform film to produce
high-speed turbulence and prevent the liquid film surface heating coke,
fouling, thereby improving the overall transfer coefficient. Light
components are formed by evaporation vapor stream to rise through the
vapor-liquid separator to reach the external condenser and evaporator
are directly connected, the heavy component is discharged from the
evaporator at the bottom of the cone. A unique distributor not only has a
uniform material flow to the inner wall of the evaporator, to prevent
the material spilled inside the evaporator is injected into the steam
flow, also preventing just entering the material here flashed in favor
of the elimination of foam, the material only evaporate along the
heating surface. In the upper wiped film evaporator with a design based
on the material properties of a centrifugal separator, the steam flow
will rise droplets separated and return to the hopper.
