ASTM D3451 ASTM D3794 Câmara de teste de envelhecimento UV

Introdução

Ultraviolet accelerated aging test box is our company’s ultraviolet accelerated aging test in luv-i

On the basis of the box of newly developed micro-machine products, the technical parameters fully comply with the national standard.

GB/T1865-2009;ISO11341:2004 artificial weathering and radiation exposure of paints and varnishes.

ISO4892 plastics – methods for exposure to laboratory light sources ASTM D3451 coatings powders and powder coatings Testing », ASTM D3794« testing of coil coatings ».The instrument adopts LCD display

Intuitive, fácil de operar, replacing the (old) luv-ii instrument cumbersome operation;High precision digital temperature is adopted

The temperature control precision is greatly improved by degree sensor and PID adjustment.It also added the ability to remember time,

The sudden power failure during the test process is avoided, which causes the test to start again.

Product overview

This device is suitable for predicting paint, Revestimento, plastic and other metals through light and water exposure accelerated aging test

The relative durability of materials, especially suitable for observing the physical property damage of especially durable materials, such as reduced luster,

Fogging, strength reduction, powdering, cracking, foaming, embrittlement and fading, etc.

As with other laboratory accelerated tests, the results of this device cannot be used as a substitute for natural exposure.

The actual durability of the material is determined, but the contrastive test conditions provided by this device can quickly evaluate the resistance to aging of the material.

It is relatively practical to optimize performance, screen or improve old and new formulas, and monitor product quality.

Ultraviolet light is the main factor that causes the durability of outdoor products to decline, coupled with fluorescent lamps
