CHINA NBC-HB-150B Non-yellowing Test Chamber without turntable

NBC-HB-150B

Yellowing resistance testing machine

Without turntable, Light source UV300W bulb, Heating mode is hot air circulation, RT +~ 200 ℃ temperature range, control accuracy +/- 3 ℃, can do two tests: aging and yellowing resistance.

Introduction

The yellowing resistance irradiation Test Chamber is suitable for simulating sunlight's ultraviolet radiation and heat. The sample is exposed to ultraviolet rays and temperature in the machine. After a period of time, the degree of yellowing resistance of the sample is observed. The stained gray mark can be used as a reference to determine The yellowing grade test time depends on the manufacturer's agreement. The machine has complete accessories and can be used as a basic yellowing resistance test. It can also be used as an aging testing machine and oven. It has a multi-purpose function.

Yellowing resistance and aging test

This product can be tested in two ways: aging and yellowing resistance.

Aging: This machine can promote the deterioration of vulcanized rubber to calculate the change rate of tension and elongation before and after heating. It is generally believed that one day of testing at 70℃ is theoretically equivalent to 6 months of exposure to the atmosphere;

Anti-yellowing: This machine is exposed to ultraviolet rays from sunlight in a simulated atmospheric environment. The appearance changes are generally considered tested at 50℃ for 9 hours, which is theoretically equivalent to the device being exposed to the atmosphere for 8 months.
