Reaction kettle for producing liquid barium-zinc heat stabilizer

Abstract

The invention discloses a reaction kettle for producing liquid barium-zinc heat stabilizer, which comprises a shell, an agitator, and a heater, the agitator comprises an agitating shaft and blades, the blades are fixed on the agitating shaft, the agitating shaft extends into the shell, a feed inlet and a discharge outlet are arranged on the shell, the heater is embedded in the blades, the heater comprises heating resistance wires and wires, the heating resistance wires are coiled in the blades, the wires are connected to a power supply, the agitating shaft is provided with vertical slide ways, the blades are fastened in the vertical slide ways by means of sliding shafts, pneumatic cylinders are mounted on the agitating shaft, and the other ends of the pneumatic cylinders are connected to the sliding shafts of the blades. When the reaction kettle for producing liquid barium-zinc heat stabilizer disclosed by the invention is utilized to prepare liquid barium-zinc heat stabilizer, the agitator can move up and down, consequently, substances can be promoted to be uniformly heated, reaction is thorough, the heat preservation time is shortened, and the production efficiency is increased.

Description

technical field [0001] The invention relates to equipment used in the production of a liquid barium-zinc heat stabilizer, in particular to a used reaction kettle. Background technique [0002] Liquid barium zinc heat stabilizer can increase the stability of solutions, colloids, solids, and mixtures. It can slow down reactions, maintain chemical balance, reduce surface tension, and prevent light, thermal decomposition, or oxidative decomposition. Liquid barium zinc heat stabilizers have different properties due to their different compositions. However, it is generally light yellow to yellow clear liquid, with a specific gravity of 0.95-1.02 at room temperature, a viscosity of less than 100 centipoise, and a freezing point of about -15°C. Similar to liquid barium zinc, it has excellent thermal and light stability, low initial coloration, good transparency and color stability. The importance of liquid barium-zinc heat stabilizers is increasing day by day. At present, there ar...
