QUV系列試驗(yàn)箱可以模擬由陽(yáng)光，雨水和露水造成的危害，QUV利用熒光紫外（UV）燈模擬陽(yáng)光照射的效果，利用冷擬濕氣模擬魚水和露水。被測(cè)試材料放置于一定溫度下的光照和濕氣交替的循環(huán)程序中. QUV用數(shù)天或數(shù)周的測(cè)試，即可重現(xiàn)戶外數(shù)月至數(shù)年出現(xiàn)的危害。危害類型包括：褪色、變色、失光、粉化、裂痕、渾濁、泡化、脆化、強(qiáng)度、衰退和氧化。

DH-QUV/Spray系列紫外燈耐候試驗(yàn)機(jī)可以幫助您選擇新材料的變化，QUV可以測(cè)出**的相關(guān)預(yù)測(cè)結(jié)果。

The QUV simulates the effect of sunlight with fluorescent ultraviolet(UV)lamps ,while it simulates rain and dew with condensing humidity or waters ,the QUV can reproduce the damage tha t occurs over months or years outdoors .types of damage include fading,color change ,chalking ,cracking ,crazing ,embitterment ,strength loss etc the test data can help in the selection of new materials ,the improvement of existing materials or the evaluation of how changes in formulations affect product durability.
