Description

A uniformly heated kneader for the production of plastic masterbatch

technical field

The invention relates to the technical field of masterbatch production, in particular to a uniformly heated kneader for producing plastic masterbatches.

Background technique

The color masterbatch is a plastic colorant that is well dispersed with a high proportion of pigments or additives and thermoplastic resins. The selected resin has good wetting and dispersing effects on the colorant, and has a good compatibility with the material to be colored. Capacitance. That is: pigment + carrier + additive = masterbatch. After the color masterbatch is mixed by a high-speed mixer, it is crushed, extruded and drawn into pellets,

In the process of plastic processing, color masterbatch has obvious advantages such as high concentration, good dispersion and cleanliness. The kneader is an ideal equipment for kneading, mixing, vulcanization and polymerization of high-viscosity and elastic-plastic materials. The kneader can be used to produce silicone rubber, sealant, hot melt adhesive, food rubber base, pharmaceutical preparations, etc. The kneader is a special mixing and stirring device with two Σ paddles. The fast paddle usually rotates at 42 rpm, and the slow paddle usually rotates at 28 rpm. Different paddle speeds make the kneaded materials quickly Mix well.

The traditional kneader consists of a closed mixing tank, a transmission system and an electric control system. The mixing cylinder is provided with a material inlet and a material outlet, and is provided with corresponding ventilation channels. The kneader needs to heat the raw materials, but the traditional kneader uses hot oil flowing in the jacket for heating, so there is a problem of uneven heating of the raw materials inside, and the raw materials generate suspended particles in the agitated state, these suspended particles Often all will float into the air, resulting in waste.
