Glossary

UV irradiance, also called UV intensity, is expressed in units of mW/cm₂.

A cleaning method that uses the light energy of a low-pressure mercury lamp to remove contaminating organic substances from surfaces.

A method to improve wettability by generating hydrophilic functional groups on the surface with the light energy of a low-pressure mercury lamp.

UV lamps, also called UV radiation lamps or ultraviolet lamps, are a general term for lamps whose emitted light wavelength is mainly in the ultraviolet region. They are further classified according to the pressure inside the lamp and the emission method. Typical lamps include ultra high-pressure mercury lamps, high-pressure mercury lamps, low-pressure mercury lamps, metal halide lamps, and excimer lamps.

This is a method of cleaning and surface modification that improves adhesion and bonding by removing organic film from the surface of materials and making plastic surfaces hydrophilic through the power of the light energy of short-wavelength ultraviolet rays emitted from low-pressure mercury lamps and the ozone (O₃) generated by the rays.

A functional group is a group of atoms with a specific structure in an organic compound, and compounds with the same functional group share common properties. in a UV cleaning system, active oxygen produced by UV light strikes the substrate surface and breaks the molecular chains of the surface layer, reacting with the broken molecules to produce -OH, -CHO, -COOH, etc. -CHO, -COOH, and other functional groups are formed.

This unit can be built into existing customer transport equipment. The basic configuration consists of a UV irradiation unit and a lighting power supply. The unit can be built into conveyors, roll-to-roll conveyors, and other conveying equipment.

Meaning of UV irradiance and UV illuminance.

A glass made from SiO₂ with a high SiO₂ purity.

In general, the "wavelength" of light refers to the periodic length of the wave.

Substances containing carbon (C) are called "organic" and other substances are called "inorganic. However, some compounds such as carbon monoxide (CO), carbon dioxide, and salts of carbonic acid are exempted.

The transmittance of ultraviolet rays at a specific wavelength in a light-transmitting material such as glass.

It is a general term for oxygen molecules in the atmosphere that have been transformed into more reactive compounds, a type of ozone.

Organic substances that inhibit coatings, adhesion, etc. that adhere to the surface prior to UV cleaning surface modification.

A substance that readily vaporizes.

Hydrophilic refers to the ease of wetting against water.

Water repellency refers to resistance to wetting against water.

A device that measures the illuminance or irradiance of light. Unlike those generally used for camera photography, the irradiance meter used in UV cleaning and surface modification equipment must be selected according to the wavelength to be measured.

A device that regulates the amount of material that passes through the connected piping within a certain period of time.

A measuring instrument that measures the amount of water that passes through the connected piping within a certain period of time; in UV ozone cleaning and reforming equipment, it is used to measure the amount of cooling water for lamp cooling and other applications.

The area irradiated by UV (ultraviolet) rays, which tends to decrease rapidly once it is outside the area under the UV lamps, and is smaller than the light source area of the UV lamps.

Distance between the UV lamp and the object to be irradiated, also known as WD (Work Distance).

Usually, a safety mechanism installed on the equipment. In our UV cleaning and surface modification equipment, especially for batch processing types, this refers to a mechanism in which the lamp turns off when the door is opened by a limit switch as a standard feature.

Device attached to UV cleaning surface modification equipment for lamp cooling and ozone exhaust of UV irradiation equipment.

An international treaty regulating the manufacture and import/export of mercury and products containing mercury.

An allotrope of oxygen consisting of three oxygen atoms.The molecular formula isO₃。A highly corrosive, toxic gas with a characteristic fishy, pungent odor. It is produced in the air when irradiated with ultraviolet rays of short wavelengths.

In air conditioning equipment, it is a component that is installed in the middle of the piping (duct) to control the amount of airflow through the piping.
