大家常說的紫光燈，實際是黑光燈，因為這種黑光燈開啟后會發(fā)出淡淡的紫色，大家俗稱紫光燈，隨著LED技術(shù)的發(fā)展，現(xiàn)在LED黑光燈已經(jīng)替代了以前的高壓汞燈式的黑光燈。

用紫光燈照射油脂，通常會呈現(xiàn)出藍色或藍紫色的熒光。這是因為油脂中的某些成分會吸收紫外線，并在返回可見光范圍時發(fā)出熒光。

需要注意的是，不同類型的油脂在紫光燈下的熒光表現(xiàn)可能會有所不同。此外，紫光燈照射油脂并不能確定油脂的具體成分或具體油脂的含量多少，只是一種初步的可視化檢測有沒有油脂的方法。

用紫光燈照射油脂，通常有以下幾個行業(yè)：

1. 化建公司或者空分設(shè)備公司檢測氧氣管道、氧氣閥門和氧氣儲罐脫脂清洗效果。

2. 制藥企業(yè)對反應(yīng)釜等設(shè)備的核黃素清潔驗證。

3. 乳制品企業(yè)、火腿廠等食品企業(yè)對生產(chǎn)設(shè)備殘留脂肪類物質(zhì)的檢查。

5. 生產(chǎn)電腦屏幕手機屏幕等玻璃制品的公司對產(chǎn)品上殘留的手印的檢查。

美國路陽是專業(yè)研發(fā)生產(chǎn)led黑光燈的公司，有手電筒式、手持式、臺式、吊掛式等多種款式的LED黑光燈，如果你對殘留油脂檢查有需求，請咨詢美國路陽上海公司。

LUYOR UVA lamps for inspection

The light from a UVA lamp causes particles on a “clean” surface to light up.

UVA lamps can be used on all types of surfaces to spot leaks, pollution and particles:

• Control of tools and machine components

• Sources of pollution in clean rooms and laboratories

• Check cleaning quality

• Identification of risk areas

• Quality control of textiles, etc.

• Leak control in components

• Training and testing of hand hygiene

The lamps can be used with or without the use of fluorescent liquids/powders.

The hand-held lamps are useful in many areas:

UVA lamps can detect defects in LCD screens, identify impurities in medical textiles and find surface defects in machine components etc.

The light highlights “invisible” contamination in sterile environments, surface contamination of items such as spills, leaks, etc.

Clearcoat validation

luyor UV fluorescent inspection lamps are commonly used for clearcoat validation on printed circuit boards to ensure even coverage.

Detection of hydrocarbons

Most hydrocarbons will naturally fluoresce under LUYOR UV blacklight illumination and therefore this process is absolutely essential for all oxygen vessel and plant manufacturers.

Citrus fruit inspection

LUYOR  UV fluorescent inspection lamps are used as part of the quality control process during the processing of citrus fruits. Under our high-performance UV-A blacklights, hidden contamination and bruising will be highlighted.

Hygiene and cleanliness monitoring

UV inspection offers a quick, easy and effective method for improving cleanliness in hospitals, by monitoring the effectiveness of cleaning programme’s and benchmarking.

Hydrocarbons

The smallest amount of hydrocarbon contamination (oil or grease) within an oxygen vessel or connecting pipework can result in catastrophic consequences. It is literally an explosive mixture.Most hydrocarbons will naturally fluoresce under UV blacklight illumination and therefore this process is absolutely essential for all oxygen vessel and plant manufacturers.We have a wide range of UV blacklights for fluorescent inspection, your equipment selection criteria should be based on your particular process requirements:UV wavelength (usually 365 nm for fluorescent inspection applications)Minimum UV irradiance levels (dictated by working standards or ambient light levels)Inspection area (exposure should be restricted to the working area)Our friendly, helpful team have over 15 years experience in helping organisations implement a safe and effective UV light process, so should you wish to discuss you requirements or request a quotation for suitable solution, please send us a message.
