UVProduct Introduction

I. Principle of ultraviolet rays

Ultraviolet rays are invisible light waves to the naked eye, existing outside the ultraviolet end of the spectrum, hence the name ultraviolet. Ultraviolet rays are one of the electromagnetic waves from solar radiation. Generally, ultraviolet rays are classified into four categories according to their wavelengths as follows:

Light is a special form of the movement of matter, which is a stream of particles that are not connected. Every wavelength253.7nmThe ultraviolet photons have4.9eVYes. When ultraviolet rays are exposed to microorganisms, transmission and accumulation occur. The accumulation results in the inactivation of microorganisms, thus achieving the purpose. When the virus absorption exceeds3600~65000uW/c㎡At the time of dosage, for the deoxyribonucleic acid of the virusDNAAnd ribonucleic acidRNAIt has a powerful destructive force, capable of causing viruses to lose their viability and reproductive capacity, and thereby eliminating them to achieve the desired effect. On the one hand, ultraviolet rays can cause nucleic acid mutations, hinder their replication, block transcription and the synthesis of proteins; On the other hand, the generation of free radicals can cause photoionization, thereby leading to cell death.

The principle of the ultraviolet device is that the irradiation intensity of the ultraviolet lamp tube, that is, the irradiation intensity emitted by the ultraviolet lamp, is inversely proportional to the distance of the illuminated object. When the irradiation intensity is constant, the longer the illuminated object stays and the closer it is to the lamp tube, the better the effect will be; conversely, it will be worse.

The various types of ultraviolet devices from Ruilang have the advantages of high stability of irradiation intensity and long service life9000Hours, high transmittance quartz glass tube, light transmittance≥87％The unit price is also moderate compared with similar products, and the lifespan is up to7000Hours later, its irradiance was253.7umIt remains stable and unchanged, and the irradiation intensity is more stable and unchanged than that of similar domestic products. There will be an audible and visual alarm to remind when the lamp tube breaks. High-brightness mirror surface reaction chamber design. Compared with similar foreign products, its strength has been enhanced18％-27％The rate can be achieved99.99％.

Both the inside and outside of the main body of the Ruilang ultraviolet device are made of304#or316#Made of stainless steel, the main body is polished both inside and out to enhance the ultraviolet irradiance, ensuring that the object will not have any problems during the process.

Ii. Application of Ultraviolet Devices

The ultraviolet device is a new type of environmentally friendly product nowadays. In Europe and America, the ultraviolet function is applied to the surface of large areas and Spaces of objects. The usage rate and popularization rate in many aspects such as water treatment plants, industry, processing, biochemical, and household water intake and exhaust or air needs are increasing year by year.

Its main application fields include:

☆Purified water, tap water, direct drinking water, purified water, secondary water supply systems for residential buildings, communities and office buildings Water supply for hotels and restaurants, etc

☆Water for seawater and freshwater breeding and aquaculture (fish, eel, shrimp, abalone, shellfish, etc.)

☆Aquatic product processing purification, shellfish purification, fish processing and processing water, etc

☆It is used for processing industrial water, fruit juice, milk, beverages, beer, edible oil and various canned foods, cold drink products, etc

water

☆Pure water for the production of biological, chemical pharmaceuticals and cosmetics

☆Ultra-pure water for the electronics industry

☆Sewage, municipal sewage, reclaimed water reuse, hospital water, oilfield reinjection water

☆Circulating water: swimming pool water, landscape water, industrial circulating cooling water

☆Algae removal for agricultural irrigation water and large water bodies

☆Water supply for military bases, field operations, aircraft, ships and submarines

☆Air conditioning system air, indoor air, etc
