UV disinfection is generally only used for air and instrument surface disinfection. Surgical dressings cannot be treated by UV radiation as a routine method. Ultraviolet radiation is the general term of radiation in electromagnetic spectrum with wavelength from 10nm to 400nm, which can not cause people's vision. In 1801, German physicist Ritter found that the ultraviolet ray could sensitize the photographic negative containing silver bromide at the outer part of the ultraviolet end of the sunlight spectrum, so he found the existence of ultraviolet ray. Too much ultraviolet rays entering the body will cause skin cancer. production Silver ion sterilization It can be disinfected after use every day. It should be disinfected two or three times a week. It is recommended that the toothbrush head should be replaced every three months. It can be disinfected every day. The SEGA toothbrush sterilizer I selected should be disinfected for 6-8 minutes each time. It is a good ultraviolet disinfection lamp. It needs to be equipped with a ballast. Mould formation is due to long-term lack of ventilation and humidity, Silver ion sterilization manufactor If ventilation and moisture removal are available, mold will not grow. Since mold has been formed, first kill it with a mold remover, and then put a moisture bag such as a charcoal bag. I often do on-site mildew and odor removal projects. You can sprinkle lime on the corner of the wall or place charcoal in the house to absorb moisture when the house is wet. In addition, don't open the window in foggy or rainy weather. Open the window in good weather to ventilate in time.
Have you ever thought about whether you need a sterilizer on your water tank? If so, which Z is better? An aquarium scientist's differences between ozone and ultraviolet sterilizers. Ozone is a gas composed of three oxygen atoms, while the oxygen we breathe is composed of two oxygen atoms. This chemical structure makes ozone highly active, production Silver ion sterilization That's why it's such a powerful sterilizer. Silver ion sterilization manufactor It is meaningful that the bulb in the UV germicidal lamp is made of quartz, because quartz will not filter out the UV rays. However, water filters light according to its depth. Therefore, the water flow space between the quartz bulb and the external glass or plastic tube is usually only a few millimeters - a thicker space will reduce the intensity of ultraviolet rays and allow bacteria and other microorganisms to survive.
According to different lamp tubes, ultraviolet sterilization lamps have thermal cathode low-pressure mercury vapor discharge lamps and cathode low-pressure mercury vapor discharge lamps; The hot cathode low-pressure mercury vapor discharge lamps can be divided into straight type, H-type, U-type tube, etc. from the appearance; production Silver ion sterilization For different needs, it can be divided into low (no ozone), ozone, high ozone, etc. The portable microwave electrodeless ultraviolet sterilization equipment can be used for close mobile irradiation, and the ultraviolet lamp suspension irradiation can also be used. Small articles can be irradiated in the ultraviolet disinfection box. Different kinds of microorganisms have different sensitivity to ultraviolet rays. When using ultraviolet rays for disinfection, the radiation dose must be used to reach the radiation dose required to kill the target microorganisms. Silver ion sterilization manufactor The product of the irradiation intensity and irradiation time of the ultraviolet lamp used for irradiation dose at the surface of the irradiated object. Therefore, according to the irradiation intensity of the ultraviolet light source, the required irradiation time can be calculated.
Stainless steel wire woven filter screen is often used, 30-40 hole/cm filter screen is used for crude oil filtration, and 140-180 hole/cm filter screen is used for decolorization oil filtration. production Silver ion sterilization The selection of filter medium will affect the clarification of filtered oil and fat, and whether the cake unloading is smooth. The filter media used in the grease industry are mostly woven media, Silver ion sterilization manufactor Common cotton fabrics such as canvas, twill and ordinary white muslin with 20 yarns and 5-8 strands.
The sterilization principle of microwave electrodeless ultraviolet sterilization equipment is to use the sterilization ability of ultraviolet light. Can ultraviolet light directly kill microorganisms? Silver ion sterilization manufactor According to different biological effects, ultraviolet light is generally divided into four parts according to wavelength: A-band (UV-A), production Silver ion sterilization Also known as black spot effect ultraviolet (400 ~ 320 nm); B band (UV-B), also known as erythema effect ultraviolet (320 ~ 275 nm); C-band (UV-C), also known as sterilization ultraviolet (275 ~ 200 nm); D-band (UV-D), also known as vacuum ultraviolet ray (200-100 nm). C-band ultraviolet light is mainly used for water disinfection.
The sterilization principle of the microwave ultraviolet water treatment equipment is mainly to use the irradiation intensity of the ultraviolet lamp, that is, the radiation intensity emitted by the ultraviolet sterilization lamp, which is inversely proportional to the distance of the irradiated disinfectant. Therefore, when the irradiation reaches a certain level, the disinfectant it is exposed to will stay longer, and the closer it is to the sterilization lamp, the better the sterilization effect will be, otherwise, the worse it will be. So, what are the sterilization principles and application characteristics of the submerged microwave ultraviolet water treatment equipment? Now, let's discuss it with you! After absorbing ultraviolet rays, microorganisms will cause some changes in the structure of nucleoprotein molecules in their own cells, resulting in protein denaturation and breakage on the DNA chain, as well as destruction of cross links in DNA molecules, hydration on cytosine and uracil, and even dimers on adenosine, Because dimerization destroys the normal pairing of purine and pyrimidine, it changes the biological activity of DNA. As a result, the metabolism of microorganisms will be hindered, and they cannot proliferate, produce cells and destroy them; Causes the synthesis of proteins and enzymes in bacteria to be blocked, production Silver ion sterilization As a result, the structure and function will be changed and destroyed, which will lead to the death of microorganisms and achieve the purpose of disinfection and sterilization. Experiments have proved that UV is the most bactericidal in the range of 240nm to 280nm, especially when the wavelength is 253.7 μ m, Silver ion sterilization manufactor The germicidal effect of ultraviolet radiation is the best. Because a section of C frequency in the ultraviolet ray is very effective in destroying harmful bacteria or viruses. Because UV can kill bacteria, molds, viruses, unicellular algae and other organisms, UV is the preferred equipment for sterilization in the microwave UV water treatment equipment industry.
