Abstract

The invention discloses a multi-combined high-vacuum purifying system. The material of a five-layer metal net is 304 with the mesh of 40; due to the adoption of two-stage condensation, liquid nitrogen is volatilized at normal temperature to take away heat in a pipeline so that gas in the pipeline is cooled; and the purity of a small organic molecular electroluminescent material has important influences on the working life and the efficiency of an OLED device. By using the multi-combined high-vacuum purifying system, the problem that the sublimation purification efficiency is reduced because the cooling period of the traditional equipment is long is solved; and an electric push rod is used as a power unit at present, a split furnace body arranged on a linear guide rail can be separated and combined, and then, a heat radiating fan dead against the lower part of a furnace tube blows air upwards, so that rapid cooling is realized.

Description

technical field [0001] The invention relates to a multiple compound purification high-vacuum purification system, in particular to a high-quality, high-purity organic small molecule material purification device for separating and purifying different component materials at different sublimation temperatures. Background technique [0002] In 1977, it was found that the electrical conductivity of polyacetylene film could be increased by 12 orders of magnitude by doping, from an insulator to a conductor. Since then, a new research field has been opened up, that is, organic materials as physical functional (optical, electrical, magnetic) materials Research. As a new generation of information functional materials, organic semiconductor materials are attracting the attention of the world with their remarkable advantages such as excellent photoelectric performance, low production cost, simple processing technology, wide range of material selection, soft mechanical properties, and co...
