The mixing device can realize accurate metering and accurate mixing of nanometer montmorillonite and PET resin particles.

Description

technical field [0001] The invention relates to a mixing system, in particular to a mixer for accurately mixing nanometer montmorillonite and polyethylene terephthalate (hereinafter referred to as PET). Background technique [0002] PET is mainly used for fibers, bottles and films. The performance of PET resin is very attractive, but its melting point strength is poor, the crystallization speed is slow, and its stability is poor, which restricts the large-scale use of PET plastics. In particular, the use of PET in bottle materials has narrowed and is particularly prominent. It is mainly used for water bottle materials, carbonic acid, tea and fruit juice drinks, etc., but due to its poor permeability and heat resistance, the storage period of carbonic acid, tea drinks and dairy products In order to improve the above performance of PET, it is necessary to precisely match the organic nano-montmorillonite with the PET resin particles. [0003] At present, the mixing of nano-mon...

AI Technical Summary

Problems solved by technology

[0003] At present, the mixing of nano-montmorillonite and PET resin particles is mostly carried out manually in the hopper, or by external vibration and shaking according to measurement and weighing. Due to the large error of human operation, the mixing effect is poor.

The purpose of the present invention is to propose a mixing system with accurate measurement and uniform mixing, aiming at the phenomenon that nano-montmorillonite powder and PET pellets are easy to form uneven mixing, fuzzy proportion, easy layering and bridging during the mixing process.
