222nm belongs to UVC band, and its pathogen elimination mechanism is consistent with 254nm. And the effect is better. According to the Treatment of Pneumonia in Coronavirus Infection (Trial Coronavirus Fifth Edition),novel Coronavirus belongs to the beta coronavirus. It is sensitive to ultraviolet disinfection light and heat.Ultraviolet disinfection is mainly in THE application of UVC (200nm-280nm). It can affect the microbial nucleic acid, destroy the structure of nucleic acid. It will also destroy the structure and function of microbial protein. So as to achieve the effect of eliminating bacteria and viruses.222nm belongs to the UVC disinfection band range, but shorter [...]

Since this year, due to the dense gram si mutant strain strong confidentiality, infectious higher characteristic. Our country new crown outbreak rendered more eruptions. The characteristics of high aggregation especially the Shanghai outbreak of proximal time. Making the epidemic prevention control is facing more complex difficult situation. Scientific and accurate for epidemic prevention and control. nd also put forward higher request to cut off the spread of the virus chain. And also put forward higher request to cut off the spread of the virus chain. At present, the novel Coronavirus disinfection methods in China mainly include chemical and physical methods.The [...]

Industrial NDT covers applications such as workpiece defect detection and material defect detection. The characteristic of industrial NDT is that it does not damage. To test the performance of the object nor does the internal organization of the object, and changes of thermal, acoustic, optical,electrical and magnetic reactions exist in the abnormal or defective internal or external structure of the material.The method of checking and testing the type, nature, quantity, shape, position, size, distribution and change of the structure, property,state and defect of the workpiece or material inside and on the surface by physical or chemical means. And industrial flaw [...]

LED light source explosion-proof lamps with less energy consumption, high luminous efficiency, long life and environmental protection and other advantages. Such as outdoor landscape lighting, indoor lighting and industrial explosion-proof lighting.At present, there are still some shortcomings in the performance of white LED lamps. Such as light color deviation and aging.Take portable LED explosion-proof flashlight as an example. Its life can usually reach five years or longer, but long life does not equal to the stability as always.With the use of time becomes longer, LED explosion-proof torch luminous luster and stability will decline. So what kind of explosion-proof flashlight is [...]

With the LED light source technology, The brightness is getting higher and higher. Some manufacturers even claimed that tens of thousands of lumens. The improvement of light efficiency of explosion-proof flashlight especiallywhether the high lumen light source affects human health has become a new industry problem. High brightness lamps and blue light caused by human eye. Discomfort requirements explosion-proof flashlight manufacturers must pay attention to the quality of explosion-proof flashlight light source. In particular,the concept of healthy light source is forward to let us re-examine what light source explosion-proof flashlight is good. Why to pay attention to LED explosion-proof flashlight [...]

Miniature explosion-proof LED flashlight in the air tightness and explosion-proof grade are ordinary LED flashlight can not reach.Therefore, the daily maintenance of explosion-proof LED flashlight can not be in accordance. Which with the maintenance method of ordinary lighting flashlight.Improper maintenance of explosion-proof flashlight will shorten the life of explosion-proof flashlight and even lead to direct damage.Here by Shenzhen explosion-proof LED flashlight manufacturers TANK007 to tell everyone about the correct maintenance of LED explosion-proof torch method. TANK007 TX105C USB type C rechargeable firefighting explosion-proof explosion led torch light

In recent days, local epidemics of highly contagious mutant strains have brought challenges to our epidemic prevention and control.At the same time, we have learned from various media. The Joint Prevention and Control Mechanism of The State Council has "updated" the antigen detection kits aimed at improving the ability of "early detection". It doesn't have nucleic acid testing capabilities in a concentration with a relatively high risk of infection. We can use antigen detection kits (ultraviolet reagent detection lamp）to identify the source of infection in a shorter timewithout resorting to specialized laboratories or complex instruments. So as to realize the [...]

In recent days, some provinces and cities in China have witnessed frequent outbreaks of virus, presenting a complex and grim situation in prevention and control.In addition to expanding nucleic acid screening and joint prevention and control,the Joint Prevention and control Mechanism under The State Council has decided to increase the number of virus antigen test boxesas a supplementary means of nucleic acid testing in areas with serious epidemics. In the past two years, especially in early 2020,when the epidemic was at its worst, China did not promote virus antigen test kits. Why would it promote them in 2022? There are [...]

UV antigen detection lamp The novel coronavirus antigen test kit, as a supplementary means of nucleic acid testing,Joint Prevention and Control Mechanism Of The State Council is in the list of epidemic prevention measures in 2022 by the Joint Prevention and Control Mechanism Of The State Council.As we know, the sensitivity and specificity of the antigen test kits cannot be compared with nucleic acid tests,which may lead to missed detection when residents use the kits for self-testing. So what to improve the sensitivity and specificity of antigen detection kits?Today we are going to look at the causes and remedies of [...]

As a supplementary means of nucleic acid detection, the antigen test box is suitable for primary medical and health institutions.Quarantine observation personnel, including persons in home quarantine observation, close contact and sub-close contact,entry quarantine observation, sealed area and controlled area; Community residents with a need for antigen self-testing.Among the three antigen detection boxes, the fluorescent chromatography antigen detection box has the best sensitivityand specificity for qualitative and quantitative antigen reagent testing. Compared with colloidal gold and latex antigen detection boxes, fluorescent chromatography detection boxes are not as convenient as colloidal goldand latex detection boxes, the main reason is that fluorescent [...]
