About the principle and use of UV film When cutting semiconductor chips, placing the chip on the film can keep the grain intact in the cutting. Reduce the breakage caused by cutting. Ensure that the grain will not shift and drop during the normal transmission. No residuals, proper expansion. Grain is easy to remove. Water does not penetrate between grain and tape. Applications of UV film : 1.For w...

1.Ultraviolet disinfection lamp - low pressure mercury lamp - ultraviolet radiation efficiency : conversion efficiency of input electric power to UV sterilization effective radiation (%) (range of low pressure mercury lamp below 65W is 10~23%) - ultraviolet irradiance : UV germicidal effective radiation of per unit area (uW/cm2) (in 1m distance) - ultraviolet flux maintenance rate and lifetime : a...

The cost structure of quartz lens mainly includes material, dimension size, dimension precision and process complexity. 1.Materials : common materials that can pass through UVC are synthetic quartz JGS1, fused quartz JGS2 and sapphire. The transmittance of synthetic quartz JGS1 is 1-3% higher than that of fused quartz JGS2 in the UVC 250-280nm band, and its price is several times higher than that ...

UV is useful for sterilization and disinfection. But it does not just rely on UV. The main mechanism of UV sterilization is protein inactivation, is mainly UVC UV LED products. Its applications are suitable for surfaces. Studies have shown that UV mainly through the radiation damage to microorganisms and the destruction of nucleic acid function to kill microorganisms, so as to achieve the purpose ...

Let's look at the coronavirus first. Coronavirus belongs to protein-bound single strand positive RNA virus. Previously, six kinds of corona-viruses were known to infect human: α (229E, nl63) and β (OC43, hku1, mersr CoV and SARS CoV). Among them, hku1, mersr CoV and SARS CoV can cause pneumonia. The most well-known are SARS in 2003 and mers in 2012. In terms of the binding strength of virus and re...

Abstract : according to the ultraviolet killing dose of Beta-coronavirus coronavirus, such as SARS and MERS in the literature, the 99.99% lethal ultraviolet dose of 2019-nCovnovel coronavirus NCP with an initial concentration of TCID50 of about 105.8 /mL was given to be 1085 mJ/cm2, and the base model of deep ultraviolet LED with reference to surface antivirus and air purification was provided for...
