    對(duì)于某些應(yīng)用而言,水噴淋能更好地模擬zui終使用的環(huán)境條件。水噴淋在模擬由于溫度劇變和由于雨水沖刷所造成的熱沖擊或機(jī)械侵蝕是非常有效的。在某些實(shí)際應(yīng)用條件下,例如陽(yáng)光下,聚集的熱量由于突降的陣雨而迅速消散時(shí),材料的溫度就會(huì)發(fā)生急劇變化,產(chǎn)生熱沖擊,這種熱沖擊對(duì)于許多材料而言是一種考驗(yàn)。UV試驗(yàn)箱的水噴淋可以模擬熱沖擊或應(yīng)力腐蝕,同時(shí)有了噴淋系統(tǒng),試樣的整個(gè)耐氣候試驗(yàn)才更真實(shí)的再現(xiàn)了戶外光照、冷凝、淋雨的環(huán)境條件。更多產(chǎn)品信息請(qǐng)點(diǎn)擊瀏覽:www.qd-bus.com
