Abstract

The invention relates to a multifunctional plastic accelerated ageing test apparatus and a use method thereof. The apparatus is characterized in that a pure water tank is arranged at the left side of a test environment box, a control box and a chemical solution tank are arranged at the right side of the test environment box; a water spray nozzle, a salt spray nozzle and a liquid tank fixing slide rail are arranged at the bottom of the inner chamber of the test environment box, and above liquid tanks are movably connected through the liquid tank fixing slide rail to simulate long-term immersion ageing test; the water spray nozzle is used for simulating hygrothermal ageing, and the salt spray nozzle is used for simulating salt spray corrosion; and the bottoms of the water spray nozzle, the salt spray nozzle, the pure water tank and the chemical solution tank respectively communicate with an air compressor through a compressed air pipeline. The ageing test apparatus integrating multiple functions has the advantages of realization of single ageing project test, realization of comprehensive ageing performance test under the introduction of ultraviolet lights, moisture and heat, salt spray and other loading test items, short period in the comprehensive performance test, realization of thorough ageing and deterioration of most plastics within 100 h, and high test repeatability.

Description

technical field [0001] The invention relates to a plastic aging testing device and method, in particular to a multifunctional plastic accelerated aging testing device and a using method. Background technique [0002] Plastic is an important organic synthetic polymer material with a wide range of applications. Most plastics have light weight, chemical stability, corrosion resistance, good impact resistance, wear resistance, good insulation, good formability and coloring, and low processing costs. And other advantages, it occupies an important application position in non-metallic materials. At the same time, most plastics have poor heat resistance, high thermal expansion rate, easy to burn, poor dimensional stability, easy to deform, most plastics have poor low temperature resistance, become brittle at low temperature, and are easy to age. Aging phenomenon, like metal corrosion phenomenon, is the top priority of current technical research. [0003] The main reason for the ag...
