UV power puck test LED lamp and high pressure mercury lamp

lightmeter — Wed, 22 Jul 2020 02:15:12 GMT

Ultraviolet curing technology is widely used in modern times, and the energy detection of ultraviolet light sources has become important. One of the indispensable things is the UV energy meter. The purpose of the UV energy meter is to detect whether the power and energy of the UV light source meets the curing standard, to detect whether the UV light source is attenuated or needs to be replaced. UV power puck can be used to test the light source used in the exposure machine.

The process of curing a material that can be cured by ultraviolet radiation is called the UV Curing Process. The biggest difference between UV curing and traditional drying process is that traditional drying generally relies on the volatilization of the solvent in the coating material to form hardening, while the UV curing process is a photochemical reaction without solvent volatilization. UV curing light sources are mainly divided into two categories:
A: Mercury lamp
Ultraviolet curing machines have been used for a long time now with mercury lamp light source as the mainstream. The principle of the mercury lamp is that the mercury in the lamp is excited by the voltage to become mercury gas and emit ultraviolet, visible and infrared rays. The industry has been striving for improvement due to defects such as fast decay, short life, high power consumption, high cost of use, increased temperature, large volume, and mercury content. However, it has been difficult to break through the limitations of the original hardware. Ultraviolet energy meter for mercury light source detection
B: LED UV curing light source:
At the beginning of the 21st century, UV curing entered the era of LED light sources. In addition to providing stable single-wavelength UV light, different power LEDs with wavelengths of 365nm, 385nm, 395nm, and 405nm can be selected. It has also attracted more and more attention from the industry due to its environmental protection, energy saving, long life, no heat radiation, and miniaturization of equipment that traditional mercury lamps do not have. In just a few years, UV-LED curing equipment has also started from a point light source and developed into a multi-branch, multi-purpose, such as line light source, surface light source, and wireless portable light source to meet the needs of various curing occasions. It does not contain mercury, it is a new energy-saving and environmentally friendly product, which makes the UV curing of the product faster, more efficient, greener, safer and more environmentally friendly.
For UV curing box: UV energy (mJ/cm2) = UV intensity (mW/cm2) * exposure time (s); therefore, precise control of UV intensity and exposure time can accurately control UV energy. Since the UV light source will decay over time, in order to control the UV energy of the curing process to be consistent, it is necessary to monitor the UV energy value of the UV curing process with a UV energy meter, so the role of the UV energy meter is very important.

Car window tint checker test thermal insulation films

lightmeter — Sat, 09 May 2020 06:06:48 GMT

Car foils are mainly divided into front bumper films and side back bumper films. With the improvement of people's living standards, people's awareness and needs of car front bumpers and side back bumpers are also different. Today, I will analyze the difference between the front and rear side of the car.

The significance of the front barrier film is to improve the infrared blocking performance under the premise of ensuring the highest possible light transmittance. The choice of the front barrier film of the car must be within the range stipulated by the relevant national laws (the light transmittance of the front barrier film must be greater than 70%) and Quality must pass. Because the front barrier must not only be anti-glare, heat-insulating, safe and explosion-proof, but also anti-ultraviolet. Drivers and passengers view the road conditions and scenery in front through the front barrier, and are easily sunburned or dazzled. Therefore, when choosing a front film for a car film, you should not only look at the price of the car film, but also evaluate and select the car according to the sum of the heat insulation rate, light transmittance, and ultraviolet blocking rate of the car film.

The front windshield of the car is the main heat source transmission area in the car. If we buy and install the front windshield film of the car, it can significantly improve the temperature in the car, reduce the energy consumption of the air conditioner, and achieve the effect of energy saving. The ultraviolet shielding rate of the front screen is up to 99%, which can effectively protect the human skin and car interior from fading and discoloration.

The side shield is different, because it does not involve the problem of driving sight. It can compromise a lot on the transmittance. You can even buy a black film that costs dozens of dollars to achieve a good barrier effect, but the quality and durability It's hard to say. Of course, this is also an example. In the field of side rear barriers, infrared and ultraviolet barriers are the most important, and they are the performance indicators that everyone pays attention to when buying. High light transmission, heat resistance and sun protection are definitely no problem. But the price must be high. If you want an affordable amount and enough, in fact, you only need to be within the acceptable range of light transmittance (you can accept it yourself, but pay attention, too dark side film, but it will affect the line of sight at night) try to choose infrared and ultraviolet blocking The one with a high rate is enough.

Is it good to see the film? The data is very important. For the front-end film, the higher the light transmittance and infrared blocking rate, the better, and you can see clearly! Insulation! For the side gear, the higher the infrared blocking rate and the ultraviolet blocking rate, the better. Thermal insulation and sun protection are the king. The requirements for light transmittance vary from person to person. Use Linshang professional window tint checker to test the infrared barrier rate, ultraviolet barrier rate and visible light transmittance of automotive thermal insulation film at the same time. Choose a suitable automotive thermal insulation film scientifically and professionally. To achieve the dual effect of sun protection and light transmission.

UV energy meter principle

lightmeter — Thu, 07 May 2020 06:23:18 GMT

The Linshang UV energy meter uses an intelligent single-chip acquisition scheme. The measurement principle is to first convert the weak current signal of the ultraviolet detector into a digital signal through an ADC analog-to-digital conversion chip. Then, the single-chip computer collects the digital signal and adjusts it through software. To UV power, UV energy is obtained by integrating UV power with time. In this process, one needs analog-to-digital conversion to get the UV power, and the other needs integration to get the energy value. If high accuracy is required, the acquisition time must be fast enough, generally at least 1000 times per second, so that the integrated energy value is more accurate.

For the intelligent single chip acquisition scheme, the power value is first measured, and then the energy value is calculated. In this way, the UV energy meter adopting this scheme displays real-time power value, maximum power value and energy value at the same time. It also integrates temperature measurement.

The principle and price of UV energy meter

Linshang UV energy meter LS128 adopts high-speed multi-point acquisition, which can simultaneously test power, energy, temperature and time. It can record all the data of the acquisition process, and get the curve data in the process. It is convenient to analyze the UV intensity distribution and temperature distribution of various points in the curing furnace, as well as process analysis and process parameter formulation during the production process.

Paint thickness gauge for the used car industry

lightmeter — Wed, 06 May 2020 06:42:27 GMT

Coating thickness gauge for used car

lightmeter — Thu, 30 Apr 2020 02:55:20 GMT

In the past, when testing vehicles, without the help of coating thickness gauges, it was undoubtedly a major problem to detect the thickness of the body paint. It also played a great role in identifying whether it was a used car, and formed a protection and decoration on the body surface. The coatings, such as coatings, coatings, claddings, coatings, and chemically generated films, are called claddings in relevant national and international standards. The measurement of cladding thickness has become an important part of vehicle quality inspection, and it is also an excellent product. The necessary means of quality standards.

In the process of internationalization, China's export vehicles have clear requirements for the thickness of the cladding. Due to the characteristics of small accuracy and error, high reliability, high stability and easy operation in the measurement process of the coating thickness gauge, the coating thickness gauge plays an important role in controlling and ensuring product quality, which is necessary for vehicle inspection Essential measuring instruments.

First, the factors that affect the accuracy of the coating thickness gauge test results

1. The effect of whether the film thickness correction sheet is qualified on the test result

As the measurement standard of the coating thickness gauge, the film thickness correction sheet needs to be inspected by the technical supervision department and attached with the inspection report. However, it is not common among instruments at home and abroad. It is precisely because of this that the instrument measures Accuracy and reliability are affected by whether the film thickness correction sheet passes the qualified test.

2. The influence of the degree of probe wear on the test results

When the coating thickness gauge is used to detect the thickness of the vehicle coating, the probe inevitably contacts the vehicle shell, so the most susceptible part of the thickness gauge is the probe. The life of a thickness gauge probe It also determines the use of the thickness gauge.

3. Whether the detected substrate exceeds the detection range of the instrument has an influence on the detection result

The instrument belongs to the standard measurement range for the detected vehicle materials. If the substrate measured during the detection is not within the detection range of the thickness gauge, the results displayed by the instrument will lack accuracy.

lightmeter — Wed, 29 Apr 2020 02:35:34 GMT

Adhesion is a very important concept for the coating and the substrate. Adhesion can make the coating and the substrate firmly bonded together by physical or chemical action, and it is not easy to fall off. So that the coating and the substrate are well combined, so that the role of the coating can be better played. For example, the better the adhesion between the fireproof coating and the anticorrosive coating, the better the performance of the fireproof coating and the anticorrosive coating. Therefore, in order to effectively improve the adhesion of the coating, we generally need to degrease, derust, etc. the coating. After processing the coating on the brush, a coating thickness gauge is usually used to measure the thickness of the coating.
