Anticorrosive coating thickness measurement

Anticorrosive paint is a type of paint used on the surface of an object to protect the inside of the object from corrosion. It is a kind of paint commonly used in industrial construction. It is widely used in aviation, shipbuilding, chemical industry, oil pipeline, steel structure, bridge, oil drilling platform and other fields, and is favored by the majority of construction manufacturers. Paint thickness meter can be used to test the coating thickness. There are many types of anti-corrosion paints. According to the composition, they can be generally divided into: epoxy anti-corrosion paint, polyurethane anti-corrosion paint, acrylic anti-corrosion paint, inorganic anti-corrosion paint, perchloroethylene anti-corrosion paint...

Ultraviolet disinfection

The principle of ultraviolet disinfection Using ultraviolet , the bacterial protein is photolyzed and denatured, and therefore the aminoalkanoic acid , macromolecule and enzyme of the bacterial body are destroyed and died. At an equivalent time, when ultraviolet rays undergo the air, the oxygen within the air is ionized to supply ozone, which strengthens the sterilization effect. Ultraviolet rays are mostly used for disinfection of air and object surfaces, with a wavelength of 2573A. it's used for air disinfection, the effective distance doesn't exceed Zm, the irradiation time is 30-60min, and it's used for disinfection of objects.The effective distance is 25-60cm, the irradiation time is 20-30min, and therefore the timer starts from...

Bluetooth UV light meter

The UV light meter LS126C is designed in accordance with the detection requirements of germicidal lamps. It is equipped with a 1-meter test hook when leaving the factory, which is convenient for on-site UV intensity measurement. First connect the instrument to the APP dedicated to the mobile phone, hang the instrument 1 meter vertically below the lamp tube during measurement, and then turn on the UV germicidal lamp after the measurement personnel leave. You can view the data directly on the mobile phone. It can be said that the UV intensity tester realizes wireless detection of UV intensity. LS126C UV light meter is a professional instrument for measuring the intensity of UVC ultraviolet germicidal lamps, that is, the ultraviolet...

Coating thickness gauge calibration

Correct coating thickness gauge calibration is essential to accurately measure bai. For calibration, a sample similar to the object to be measured later will be used, that is, at the same time, the standard sample and the object to be measured should have the same shape and geometry. Basically, the more standard samples of the measurement object match, the measurement result will be more accurate. 2. Make sure that the following properties of the calibration sample and the object to be measured match: - The radius of curvature of the surface - The substrate material (such as permeability, conductivity; in an ideal way, the standard sample and the measurement object should be the same material) - Substrate thickness - Measurement area...

UV mercury lamp energy meter

The application of high-pressure mercury lamps has spread to many fields. Humans have entered a new era in industrial lighting or indoor and outdoor lighting, and UV energy meters are inseparable from it.As the name implies, the high-pressure mercury lamp contains mercury in the lamp, and its components include a quartz arc tube; an outer bulb coated with phosphor; a metal bracket; a resistance component and a lamp cap. The arc tube is the core component and contains mercury and inert gas. After power on, the mercury vapor pressure in the arc tube is about 2 to 15 atmospheres, hence the name high pressure mercury lamp. The light emitted during discharge is white, and the luminosity is much higher than that of incandescent lamps. It has the advantages of simple structure, low cost, high luminous efficiency, long life, and power saving. Now it has been popularized for indoor and outdoor industrial lighting and street lighting.In addition, the application of ultraviolet high-pressure mercury lamps involves many fields. The spectral range of this lamp is between 350nm-450nm and the main peak is 365nm. It has a higher power density and effective ultraviolet wavelength. It is used in light curing; color printing ; Ink drying; furniture industry; decoration industry and outer packaging industry all require the participation of ultraviolet high-pressure mercury lamps.

UV sterilization information sharling

Seoul designs a type of product every 10nm, 255nm, 265nm, 275nm are all made, but currently the main one is still 275nm; LG keeps the two directions in parallel, on the one hand, the band decreases from 265nm to 263nm, on the other hand, it is as high as possible 278nm power, and think that 265nm is not an advantage in cost, 278nm can better meet the reality; Qingdao Jiesheng initially products at 280nm, and then gradually lean towards 270nm, although 255nm is also involved, the cost is too high and the shipment is small . On the whole, gradual increase in power on 270~280nm chips is currently the choice of most companies. It seems that this is also the most effective way to accelerate the pace of commercialization of UVC LEDs. Four big...

Paint thickness affect the car quality

The paint finish of many cars is actually different. There is still metallic du paint in Bai, but not all black cars are metallic paint. People feel that metallic paint is actually harder and better than ordinary car paint. Do you know the difference between the thickness of the paint? Many people think that the paint on the car must be a little thicker, because in this case it will be more wear-resistant, but is it really the case? Does the thickness of the paint affect the car?How much do you know about car companies and do you know the current car paint technology? In fact, the thickness of car paint is mainly related to the current advanced technology. In the past, thick car paint was needed because the technology was not advanced...

Anti-corrosion paint thickness test

Anti-corrosion paint has the effect of slowing down the corrosion of the environment to the protected materials. Although it cannot be completely isolated, it has the functions of shielding, corrosion inhibition and cathodic protection for the protected materials. Different corrosion environments have different requirements for the thickness of the anticorrosive paint of the steel structure. Only when a certain thickness of the anticorrosive paint reaches a certain thickness will there be a protective effect of response. Therefore, it is necessary to test the anticorrosive paint of the steel structure with a paint thickness gauge. Linshang LS220H is a paint thickness gauge, iron and aluminum, which is mostly used for the thickness...

Medical uv lamp intensity test

Medical ultraviolet lamps mainly sterilize and disinfect indoor air. There are two methods: indirect irradiation and direct irradiation. Indirect irradiation method: the use of high-intensity ultraviolet air sterilizer has the advantage of reliable disinfection effect and can be used when there are people indoors. The disinfection time is generally 30 minutes. The principle of indirect irradiation method is to suck dirty air into the disinfection machine. The ultraviolet lamp is sealed in the disinfection room of the chassis of the air sterilizer, and the dirty air is filtered and sterilized before it is released. Since the ozone concentration in the air when the sterilizer is working is ≤0.1 mg/m³, human-machine coexistence can...

Automotive paint meter

In the detection of the automotive paint meter LS220, the car roof is generally used as a reference. If the value of other parts is significantly higher than the reference value, the part of the vehicle can be judged that it has been repaired by sheet metal and spray paint. In the second-hand car identification process, if the inspector finds that the difference between the value and the reference value is very large, it will further check whether the vehicle has traces of accidents there and determine whether it is an accident. Generally, the thickness of most cars is between 80-140, and a small number of imported cars may reach more than 150. If you test the left door of the car, you can take the five points of the door up, down...
