Ultraviolet ray refers to the light with the wavelength of 200nm to 400nm in the sunlight, which is divided into long wave UVA, medium wave UVB and short wave UVC.
Short wave UVC is absorbed by the ozone layer when passing through the stratosphere of the earth's surface and cannot reach the earth's surface; Medium wave UVB has erythema effect on human body, which will make the skin tanned and cause redness, swelling and peeling; Long wave UVA can reach the dermis of the skin and destroy our skin.
Ultraviolet rays also have a strong damage effect on materials, so most people are committed to studying ultraviolet absorbers in order to completely shield ultraviolet rays from materials. More and more ultraviolet absorbers of different types and bands appear in the market. But Ultraviolet rays also has good effect:
● Sterilization
The UVC is extremely destructive to microorganisms, and can destroy the nuclear protein and deoxyribonucleic acid (DNA) of bacteria, thereby killing bacteria. For example, ultraviolet mercury lamp is used to sterilize air and food.
● Health care function
UVB can cause the photochemical process and photoelectric reaction of the skin and body to produce many active substances.
● Decomposing lampblack
Ultraviolet light is used to change the molecular chain of oil and fat. The organic matter in the lampblack is photodegradated and oxidized, and the odor is also eliminated.
Promote the production of vitamins and decompose organics.....
With the deepening of people's understanding of UV, the market has put forward the requirement---selective UV absorption.
OMNISTAB® SA series absorbents are specially developed, which can meet customers' requirements for absorption in different bands and further expand the application field of UV absorbers.
OMNISTAB® SA7811 can focus on the absorption of UVC band, which can reduce the aging and yellowing of products after high-energy UVC irradiation, achieve disinfection effect and extend the service life of products. It is applied to medical equipment, household killing and other scenes. OMNISTAB® SA7812 is suitable for UVB absorption, especially for photovoltaic film products; OMNISTAB® SA7813 and OMNISTAB® SA7814 are used for UVA absorption, such as textile, lens, film and other industries.
