Addition type raw material rapid preparation device for photodegradable plastic production

Abstract

The invention discloses an addition type raw material rapid preparation device for photodegradable plastic production. The addition type raw material rapid preparation device for photodegradable plastic production comprises an upper configuration equipment frame body, a high-speed stirring shaft, a lower configuration equipment frame body, a low-speed stirring shaft and a speed change motor; the lower configuration equipment frame body is fixedly arranged on the bottom face of the upper configuration equipment frame body through a bolt, a discharging through opening of the bottom of the upperconfiguration equipment frame body perpendicularly communicates with the lower configuration equipment frame body, and the speed change motor is arranged on the top of the upper configuration equipment frame body; the same speed change motor is used for driving two transmission rods to rotate, power consumption in the equipment running process is reduced, before configuration, a sucking pump is used for sucking air in equipment, the problem that raw materials and air are mixed, and bubbles exist in plastic is solved, a single and dual spiral strip-shaped stirring paddle achieves multi-vortex stirring, low-shear non-bubble uniform mixing of materials is achieved, due to low-rotating-speed stirring, bubbles generated due to stirring can be effectively reduced, and the material component cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of photodegradable plastic production, in particular to an additive-type rapid preparation device for raw materials for photodegradable plastic production. Background technique [0002] Photodegradable plastics refer to plastics that can degrade after being irradiated with light. Once the product is buried in the soil and loses light, the degradation process stops. The production process is simple and the cost is low, and the disadvantage is that the degradation process is greatly affected by environmental conditions. Photodegradable plastics are divided into two types: copolymerization type and additive type. The former is a plastic composed of a copolymer synthesized from carbon monoxide or carbon-containing monomers and ethylene or other olefin monomers. Because the polymer chain contains chromophoric groups such as carbonyl groups and weak bonds, it is easy to undergo photodegradation. The latter is p...
