Note for UV disinfection lamp

Note for UV disinfection lamp: 1. When using ultraviolet disinfection lamps, people, animals and plants must leave the scene. 2. don't stare at the ultraviolet disinfection lamp for an extended time. Ultraviolet rays can damage human skin and mucous membranes to a particular extent. When using ultraviolet disinfection lamps, concentrate to protection. The eyes must not look directly at the ultraviolet source, otherwise the eyes are going to be hurt. 3. When disinfecting items with ultraviolet disinfection lamps, spread or hang the things to expand the irradiation surface. The effective distance is one meter, and therefore the irradiation is about half-hour . 4. When using ultraviolet disinfection lamps, the environment should be kept...

UV sterilization

Ultraviolet rays are divided into three types according to wavelength: long-wave ultraviolet, medium-wave ultraviolet and short-wave ultraviolet. The specific ultraviolet intensity can be detected with an ultraviolet radiation meter.

Paint film performance

Paint film performance: 1. Appearance of the coating film: refers to whether the coating film is smooth, whether there are particles, bubbles, flowers, construction marks, etc. 2. Gloss: The parameter of the ability of Henry paint film to reflect light. Gloss is a very significant feature of paint film, which has a great influence on the decorative performance of paint. High-gloss paint is easy to show the defects of the substrate, so it has higher requirements for the flatness and roughness of the substrate. 3. Hardness: Hardness refers to the resistance of the paint film to foreign objects invading its surface. The hardness of the paint film is one of the important properties of its mechanical strength. Coating thickness gauge can...

UV energy meter detect high pressure mercury lamp

Since the application is so wide, the production of high-pressure mercury lamps will be very professional and rigorous. When it is necessary to know whether the energy and intensity of the high-pressure mercury lamps meet the requirements of industrial production, there is always an instrument for testing, and the UV energy meter is in Here plays an important role. It is said that using a UV energy meter to measure the energy and intensity of a high-pressure mercury lamp is good. Linshang Technology has developed two professional ultraviolet energy meters, S120 and S130, specifically for measuring high-pressure mercury lamps. So what are the advantages of these UV energy meters? For those, I will explain them one by one below...

Magnetic thickness gauges applications

Cars are closely related to our lives, and coating thickness gauges also play an important role in the automotive industry. As we all know, the thickness of a car paint is related to the quality of the car itself. Especially when buying a second-hand car, the uneven thickness of the paint may mean that the car is repainted after being worn out by impact, and the overall safety will be greatly reduced. The coating thickness gauge can detect the thickness of the non-magnetic coating on the magnetic metal substrate such as steel, and it can naturally be used to detect the thickness of the coating paint on the car. In addition, the chrome plating of the mold, the hard chrome plating of the roller, the chrome plating of the outer surface...

Purpose of coating thickness testing

What is the purpose of coating thickness testing?The anticorrosion coating of the steel structure is dominated by paint materials, and rubber, plastic and other materials may be used for special projects. The judgment of the anti-corrosion effect is generally based on the thickness of the coating. The anti-corrosion coating thickness test should be conducted after the coating is dried, and there should be no condensation on the surface of the component during the test; if there is a quality problem in the appearance of the component coating before testing, it should be repaired, and the coating thickness should be tested after repair.How to measure the coating thickness?

High precision coating thickness gauge

Linshang LS223 high-precision coating thickness gauge is a dual-purpose iron and aluminum instrument, suitable for the measurement of non-magnetic coatings on ferromagnetic metal substrates such as iron and steel, and can also be used for non-magnetic coatings on non-magnetic metal substrates such as copper and aluminum. Measurement of conductive coatings. The measurement accuracy of the high-precision coating thickness gauge is: ≤±(3% reading+2μm): 0-3000μm ≤±(5% reading+2μm): 3000μm-5000μm Measuring method of high-precision coating thickness gauge Tools/raw materials High-precision coating thickness gauge Iron-based materials Non-ferrous materials Method/Step 1 First, press and hold the power button to enter the setting mode when...

UVC meter test uv lamp intensity

As a kind of light pollution, ultraviolet rays have always been considered as harmful light, and this is indeed the case. The absorption of ultraviolet rays through the skin can damage DNA (the chemical transport unit that makes up the transmission of chromosomal genes). When DNA is damaged, the cells will die or develop into uncontrollable cancer cells. This is the initial stage of tumor formation.According to the size of UV damage, people divided the UV into different levels. Ultraviolet intensity is generally expressed as 0-15. It is usually stipulated that the UV index at night is 0, and the UV is the strongest in the tropical or plateau area and when there is no cloud on a sunny day. It can be seen that the larger the value of the ultraviolet index, the greater the harm of ultraviolet radiation to the human body, and the stronger the damage to the skin in a shorter time. Sometimes, the UV index can be divided into 5 levels, that is, when the index value is 0, 1, 2, it is level 1, which means that the minimum amount of ultraviolet radiation in solar radiation has little effect on the human body; when the UV index is 3, 4, Level 2, which means that the amount of ultraviolet radiation in the solar radiation is relatively low, and the impact on the human body is relatively small; when the ultraviolet index is 5, 6, it can be called level 3, indicating that the ultraviolet radiation is of medium intensity, which has a certain degree of damage to human skin; When the UV index is 7, 8, or 9, it can be regarded as level 4, indicating that the ultraviolet radiation is strong, which is harmful to the human body, and attention should be paid to prevent it; when you go out, you should wear a sun hat, sunglasses or parasol, and you can also apply some sunscreen (The SPF index should be greater than 15). When the UV index ≥10, it can be regarded as grade 5, indicating that the ultraviolet radiation is the strongest and the most harmful to the human body. People should reduce the time of going out (especially around noon), or take active protective measures.

Working principle of UV dosimeter

The working principle of the UV dosimeter: First of all, we must first understand what is the light intensity. The light intensity refers to the degree of the object being illuminated, that is, the ratio of the light flux on the surface of the object to the area being illuminated. Ultraviolet UV illuminance meter, also known as ultraviolet radiometer, ultraviolet irradiance meter, ultraviolet intensity meter, etc., is an instrument specially used to measure light intensity and brightness. The instrument is mainly used to measure ultraviolet rays, used in photochemistry, polymer material aging, flaw detection , Health, medical, chemical, health, food, electronics, plant cultivation, large-scale integrated circuit lithography and other...

Transmittance tester used to test the performance of car film

Some main performance indicators of automobile heat insulation film: Visible light transmittance: Referred to as light transmittance, it is used to measure the percentage of visible light passing through the glass. The front barrier is generally more than 70%, and the side rear barrier is generally 5%-60%. The worse the ability, the darker the relative film color. UV rejection rate: high-quality automotive film, this index is generally not less than 98%, the highest can reach 100%. The high ultraviolet blocking rate can effectively prevent people in the car from being irradiated by excessive ultraviolet rays and burning the skin. Many inferior membranes do not have this index, or are far below the 98% standard. Infrared rejection rate:...
