uv紫外線老化試驗(yàn)箱
產(chǎn)品用途：
太陽的紫外線是導(dǎo)致所有暴露于戶外的產(chǎn)品的材料發(fā)生降解的主要原因。長崎TK-ZW系列uv紫外線老化試驗(yàn)箱可模擬太陽光中的紫外線部分，可地模擬太陽光中的短波紫外光，即從365納米到太陽光截止點(diǎn)295納米的波長范圍。特別適用于測試不同種類聚合物和穩(wěn)定劑之間的性能差異。在短短的幾天或幾周內(nèi)，可真實(shí)再現(xiàn)因光照引起的產(chǎn)品材料在幾個(gè)月甚至幾年的戶外使用所岀現(xiàn)的物理性能的老化和破壞!樣品試驗(yàn)的結(jié)果為改良產(chǎn)品品質(zhì)提供了科學(xué)依據(jù)。
Purpose: the ultraviolet radiation is the main cause for the breakdown of all the products material exposed in the sun The TK-ZW series UV aging test machine can simulate the short wave ultraviolet light in the sunlight. Namely the range of wavelengths from 365 to 295 nanometer. Especially suitable for the text of performance gap between polymer and stabilizer In just a few days or weeks, months or even years of aging and damage due to the ultraviolet radiation can be vividly reflected. The results of the sample text provide a scientific basis for the products quality improvement.
產(chǎn)品介紹：
1、本機(jī)具有潮濕模擬功能，開啟本功能，即可真實(shí)的模擬產(chǎn)品試樣在戶外潮濕侵蝕的工況。因?yàn)樵诤芏鄳敉猸h(huán)境中，產(chǎn)品可能每天的潮濕時(shí)間可長達(dá)12小時(shí)。研究表明造成這種戶外潮濕的主要因素是露水，而不是雨水。本機(jī)的加濕器可使試驗(yàn)箱在較高溫度下保持99%相對濕度，讓水蒸汽連續(xù)不斷地在樣品表面凝結(jié)，來模擬戶外的潮濕侵蝕。真實(shí)的再現(xiàn)了試樣使用的各種環(huán)境!從而得到最真實(shí)的實(shí)驗(yàn)結(jié)果。
2、本機(jī)具有熱沖擊及應(yīng)力模擬功能!在某些實(shí)際應(yīng)用條件下，例如陽光下，聚集的熱量由于突降的陣雨而迅速消散時(shí)，材料的溫度就會發(fā)生急劇變化，產(chǎn)生熱沖擊，這種熱沖擊對于許多材料而言是一種考驗(yàn)。本機(jī)采用的德國“西門子”PLC控制器可自動或手動程式模擬熱沖擊和應(yīng)力腐蝕工況。
3、可根據(jù)不同的測試條件，有二種不同的紫外燈管可選擇更換。即UVA-340燈管和UVB-313燈管（注:UVA-340燈管可地模擬太陽光中的短波紫外光，即從365納米到太陽光截止點(diǎn)295納米的波長范圍。特別適用于測試不同種類聚合物和穩(wěn)定劑之間的性能差異。UVB-313燈管主要用于質(zhì)量控制和研究開發(fā)，或?qū)δ秃蛐缘牟牧线\(yùn)行測試）
1、Humidity impersonation function allows you to forge a real outdoor wet corrosion condition. because under most outdoor situations, the products may be in moist for 12 hours or more. Study has n that this outdoor moist situation is caused by the dew, rather than the rain. The unique humidifier could help maintain a 99%relative humidity condition in the text box, which could make the stem consistently condense on the samples So as to create the outdoor wet corrosion.Vividly reflected all the situation of all the samples that s how we gonna get the most updated and real test results.
2、Heat shock resistance and stress simulation On some situations Like under the sunlight. When the gathered heat rapidly fade away due to the sudden rain, material temperature will declare sharply. which gonna lead to thermal shock. It would be a challenge for most materials. This machine adopts German “Siemens”PLC controller. It can automatically or manually programming simulation of thermal shock and stress corrosion condition.
3、Two different UV lamps for choose on different text conditions The nva-340 tube and NUV-313 tube(PS: NVA-340 could simulate the short wave ultraviolet light namely the range of wavelengths from 3 65 nanometer to 295 nanometer.expecially suitable for the text of performance gap between polymer and stabilizer. UVB-313 tube mainly focus on the quality control and research development or the text for the high weather ability material.
