UV weathering test chamber

Product Overview:

This device is suitable for accelerated aging tests via light and water exposure to predict the relative durability of non-metallic materials such as paints, coatings and plastics. It is especially ideal for observing physical property deterioration of highly durable materials, including gloss loss, haze reduction, strength decline, chalking, cracking, blistering, embrittlement and discoloration.

Advantages of Product Structure and Functions:

Like other laboratory accelerated aging tests, the test results obtained by this device cannot replace natural exposure tests to determine the actual service life of materials. However, the comparative experimental conditions provided by this device are quite practical for rapidly evaluating the anti-aging performance of materials, screening and optimizing new and existing formulas, and monitoring product quality.

Since ultraviolet light is the main light factor leading to the reduced durability of outdoor products, and fluorescent tubes feature relatively stable spectral energy distribution and low cost, UV aging test chambers have become the most widely used weather resistance testing equipment worldwide due to their advantages of high efficiency, convenience and cost-effectiveness. As a simplified model, this device is especially suitable for laboratories with limited financial budgets.

Functional Features:

Rotating sample rack balances uneven light radiation from lamp aging and batch deviation, no need for regular sample position adjustment.
Water spray system simulates humidity, rain wash and drastic temperature change to restore real aging environment.
Built-in temperature control adjusts photochemical reaction speed flexibly.
Corrosion-resistant stainless steel structure ensures long service life, simple structure for easy operation and maintenance.
