氙燈耐氣候老化試驗(yàn)箱是一種綜合氣候試驗(yàn)裝置,除進(jìn)行耐氣候老化試驗(yàn)外,還可進(jìn)行高分材料的耐光性的測(cè)試,即高分子材料暴露于模擬透過玻璃的日光光譜的人造光源下來評(píng)價(jià)材料耐光性能。耐氣候老化試驗(yàn)箱從光能、溫度、降雨或凝露、濕度這幾種主要?dú)夂蛞蛩剡M(jìn)行模擬和強(qiáng)化的試驗(yàn);采用能模擬全陽(yáng)光光譜的氙弧燈來再現(xiàn)不同環(huán)境下存在的破壞性光波。
Weather resistance test is a test device for comprehensive climate, in addition to the weathering test, also can make the high light fastness of materials testing, namely polymer materials exposed to simulated by fluorescent spectra of the glass artificial source down material light performance evaluation. Aging test box to simulate and intensified test from the main climate light, temperature, rainfall, humidity or condensation in these factors are climate resistant; with xenon arc lamp can simulate the whole spectrum of sunlight reproduction under different environments the destructive wave.
氙燈耐氣候老化試驗(yàn)箱試驗(yàn)過程中濕度的重要作用,水在結(jié)冰時(shí)膨脹,所以材料中,特別是受潮后鍍膜硬質(zhì)板系統(tǒng)中的水份會(huì)產(chǎn)生膨脹和應(yīng)力,從而導(dǎo)致涂膜的撕開、斷裂或剝落。降雨會(huì)周期性地沖洗材料表面的塵埃和污穢,同時(shí)由于降雨頻率的不同,也可能產(chǎn)生長(zhǎng)期的老化作用。當(dāng)雨水沖擊曝露表面時(shí),蒸發(fā)作用使試樣表面迅速降溫,這會(huì)導(dǎo)致材料的進(jìn)一步物理降解。冰雨或冰雹在降落時(shí)攜 帶強(qiáng)大動(dòng)能,也會(huì)導(dǎo)致涂層或油漆的物理降解。
The important role of humidity weather resistance test process, the expansion of water in the ice, so the materials, especially after wet coating hard plate system in the water will expand and stress, resulting in the film tearing, fracture or flaking. Rain will wash the material surface dust and filth periodically, at the same time, because of the different rainfall frequency, may also have the effect of long-term aging. When the rain hit the exposed surface, evaporation and make specimen surface cooling fast, further physical degradation which causes the material. Freezing rain or hail in landing with strong kinetic energy, physical degradation will lead to coating or paint.
從各種角度來看,以和OH-形式存在的濕度在氙燈耐氣候老化試驗(yàn)箱試驗(yàn)過程非常重要。在二氧化鈦加色涂層和聚合物的粉化過程中就可以觀察到濕度的化學(xué)作用。盡管無(wú)論有無(wú)氫或氫離子的化學(xué)參與,聚合物表面都會(huì)發(fā)生光化反應(yīng),但通過化學(xué)反應(yīng)吸入的水份的循環(huán)作用會(huì)加強(qiáng)(甚至導(dǎo)致)表面材料的實(shí)際物理釋放過程。濕度有時(shí)也會(huì)作為pH調(diào)節(jié)劑,特別是在考慮酸雨作用時(shí),酸雨對(duì)多種油 漆和涂層有侵腐作用。
From a variety of perspectives, exist in the form of humidity and OH- is very important in the weathering test. In the process of titanium dioxide powder color coating and polymer can be observed chemical effect of humidity. Although the chemical with or without hydrogen or hydrogen ion is involved, the polymer surface occurs photochemical reaction, but the cycle is sucked through the chemical reaction of water will strengthen (even) the actual physical surface material release process. Humidity and sometimes as pH modulators, especially considering the role of acid rain, acid rain erosion corrosion effect on many kinds of oil paint and coatings.
