The basic principle of the weather resistance test box

There are two types of wire rod coater: one is wire wrap type wire rod coater, the other is extrusion type wire rod coater. Both are the same in application. They can be used instead, but there are still some differences in the working principles of the two. ZvvTextile Testing Instruments, Testing Equipment Manufacturer

The wire wound coating rod winds steel wires of different diameters on a steel rod with a specific diameter. The film thickness control of wire wound coating rod is mainly done by winding the steel wire The difference in diameter is controlled. ZvvTextile Testing Instruments, Testing Equipment Manufacturer

Extrusion-type wire rod coaters use a cold extrusion process to extrude continuous grooves of different sizes on a smooth steel rod through which the grooves are of different sizes to control the thickness of the coated wet film. ZvvTextile Testing Instruments, Testing Equipment Manufacturer

This device uses a long-arc xenon lamp as the light source to simulate and reinforce weather resistance accelerated aging test equipment. Quickly get atmospheric aging test results that can be used to evaluate the weatherability of plastic rubber, paint coatings, textile printing and dyeing, and other materials.

The weathering test is an important means of screening formulations to optimize product composition in the process of scientific research and production, and is also an important content of product quality inspection. Materials used such as coatings and plastics, aluminum-plastic panels and automotive safety. Glass and other product standards require weather resistance testing.

The main factors causing material aging are sunlight and moisture. The weather test chamber can use the GSimulate dangers from sunlight, rain and dew. ZvvTextile Testing Instruments, Testing Equipment Manufacturer

The weather resistance test chamber simulates the effect of sunlight with xenon lamps and simulates rain and dew with condensed moisture. The tested materials are exposed to a cycle program of alternating light and humidity. At a given test temperature, the hazards experienced outdoors over months or even years can be reproduced in days or weeks. ZvvTextile Testing Instruments, Testing Equipment Manufacturer

Data from accelerated weathering tests can be useful when selecting new materials, modifying existing materials, and evaluating how formulation changes affect product durability. ZvvTextile Testing Instruments, Testing Equipment Manufacturer
