A cold light source is a light source that is excited by energy such as bioenergy, electric energy and chemical energy. Since the light source contains almost no light source of the infrared spectrum, his temperature is not higher than the ambient temperature when the cold light source emits light. This light source is an excellent light source with flashing characteristics.
UV ovens, also known as UV curing ovens, simply add ingredients that react chemically with ultraviolet light to materials such as paints, paints, adhesives, glues, etc. Then apply these materials to the cured material surface. The inside of the spread is converted into a polymer by ultraviolet irradiation in the curing oven to achieve the purpose of curing. The characteristics of this curing are: short drying time, low operating cost, high curing quality, less storage space and high cleaning efficiency. Therefore, in the UV oven, ultraviolet light from a cold light source is usually selected for curing.
What is the relationship between the UV measurement device for cold light source UV oven? We take Linshang LS128 UV measurement device to understand the UV measurement device for cold light source UV oven. First let's take a look at the main parameters of this instrument:
●Applicable functions of the instrument: Measurement of light intensity, energy and temperature of UV LED source
●Spectral range: 340nm --- 420nm, instrument, calibrated at 395nm source
●Power measurement range: 0 --- 40000 mW/cm2
●Energy measurement accuracy: ±10%, ±5% typical
●Sampling speed: 2048 times / s
The above parameters are the main parameters of the UV measurement device. "The light intensity of the UV LED source in the applicable function" indicates that this instrument is suitable for cold light sources because LED light sources are cold light sources. The key factor in determining the measurement accuracy in the above parameters is the "sampling speed". We know that cold light sources are characterized by flashing, so the energy value of light changes over time. The faster the sampling speed, the smaller the change in energy value. When the sampling speed is fast enough, we can say that the energy value is eternal. Therefore, the sampling speed directly determines the measurement accuracy of the UV measurement device. When the sampling speed of a UV measurement device is very slow, his measurement accuracy is definitely not good. Therefore, measurement accuracy and sampling speed are related.
Energy = power * time. Therefore, in the parameter table of the UV measurement device, the energy parameter is closely related to the power parameter. When the sampling speed is fast, the power value is more accurate. The more accurate the energy value measured with time is quantified.
Therefore, the UV measurement device for cold light source UV oven generally has the following characteristics:
1. With timing function, can accurately calculate the curing time. Avoid too long curing time or too short curing time, resulting in defective products.
2. With intelligent statistics, you can view the temperature and intensity graphs. Making the uv energy value more intuitive.
3. The sampling speed is fast and the measurement accuracy is high. Really measure the actual temperature in the curing machine.
4. With high temperature resistance, the instrument can run at high temperatures of 100 degrees Celsius for a long time.
5. Built-in capacity, the instrument can store more than 60,000 data.
The above information is for the UV measurement device for cold light source UV ovens. We hope these sharing experiences can help you choose the UV measurement device for cold light source UV ovens.
