Medical Face Mask Flame Resistance Tester Test principle: Pass the mask through a flame with a temperature of 800°C and a flame height of 40mm at a speed of 60mm/s. When the mask is completely out of the flame, measure the afterburning time and smoldering time of the mask. So as to achieve the purpose of judging whether the mask is flammable. Flame retardant performance index function: The flame retardant performance is an important indicator of whether the mask has undergone flame retardant finishing. The masks we wear should be made of non-flammable materials to ensure that the person wearing the mask will not burn the face due to the burning of the mask when it accidentally approaches the fire source. GESTER Mask testing machine recommendation: Mask Flame Retardant Tester GT-RA06

Respiratory Resistance Tester Test principle: By simulating the exhalation of the human body and the airflow generated by inhalation, the exhalation resistance and inhalation resistance generated when wearing the mask are detected, so as to determine whether the person wearing a mask with a certain filtering efficiency affects the normal breathing of the human body purpose. Expiratory resistance, inspiratory resistance indicators: Exhalation resistance, inhalation resistance index function Exhalation resistance and inhalation resistance are one of the important indicators that represent whether the human body will have respiratory discomfort when wearing a mask. If the resistance is too large, it will affect the normal breathing of the human body, and the more unsuitable for wearing, the masks with exhalation resistance greater than 250Pa and inhalation resistance greater than 350Pa are all unqualified products. GESTER Mask Testing Machine recommendation: Mask And Respirator Breathing Resistance Tester GT-RA03B

Synthetic Blood Penetration Resistance Tester Test principle: The air pressure generated by the air compressor simulates the blood pressure of the human body (10.6KPa-16.0KPa). 2mL of synthetic blood with a surface tension of (0.042±0.002) N/m is sprayed on the surface of the mask to detect whether the mask can prevent blood from penetrating. The role of Mask Synthetic Blood Penetration Tester indicators: When working with medical staff, especially when rescuing a patient or performing a surgical operation, the patient's blood will be splashed out, and blood is often the carrier of virus transmission, so the mask must have anti-blood penetration performance, which can To a certain extent, prevent the spread of viruses.

The Duanwu Festival, also known as The Duanyang Festival, the Dragon Boat Festival, chongwu Festival, The Dragon Festival, Zhengyang Festival, tianzhong Festival, etc., the festival is on the fifth day of the fifth lunar month, is a traditional Chinese folk festival. The holiday time for the Dragon Boat Festival is: From June 25 to June 27, 2020, there are three days in total, and work is normal on June 28 (Sunday). GESTER wishes all friends a happy Dragon Boat Festival.  

Mask Particulate Filtration Efficiency Tester Test principle: The aerosol generator converts the 2% sodium chloride solution into particles with a concentration of 30mg/m³ and a diameter of 0.075μm. According to different standards, the particles are transported into the closed cavity by adjusting different air flows. The test starts when the concentration of the upper cavity and the lower cavity of the cavity reach equilibrium, because particles will continuously enter the cavity, so when the filter material is filtered, the concentration of the lower cavity will decrease, and the concentration of the upper cavity will remain at equilibrium status. Therefore, the computer will calculate the filtration efficiency according to the concentration difference between the upper and lower chambers. Filtration efficiency index role Filtration efficiency is to determine whether the filter material of a mask has the function of filtering particles and bacteria; the higher the filtration efficiency, the better the protective effect of the mask. GESTER Mask Tester recommendation: Automatic Particulate Filter Efficiency PFE Tester GT-RA09

Mask BFE tester Test principle: Firstly, a special microbial aerosol generator is used to provide a certain concentration of microbial aerosol for the entire system, and then the microbe and the diluted air are mixed evenly through the mixing and dilution section of the instrument.Then use a stable filtration rate to send a single, moderately stable and stable microbial aerosol into the sampler, and finally the sampler samples the filter material upstream and downstream, and calculates the microbial concentration in the sampled air by calculation to obtain the converted filter material The filtration efficiency of bacteria. Bacterial filtration efficiency index function: Bacterial filtration efficiency is one of the important indicators for testing the protective effect of masks, and represents the efficiency of masks in blocking bacteria from passing through the filter material of the mask. The higher the bacterial filtration efficiency of the mask, the better the protective effect. The bacterial filtration efficiency of medical masks must be 95% to be qualified. GESTER Mask Testing Machine recommendation: Mask Bacterial Filtration Efficiency (BFE) Tester GT-RA02 Mask Bacterial Filtration Efficiency (BFE) Detector GT-RA02B

When a mask is accidentally exposed to flame, its flame retardant performance is directly related to the safety of medical personnel. Therefore, the flame retardancy of the mask is one of the important physical indicators to measure the quality of medical masks. It is related to the material of the mask fabric itself on the one hand, and the flame retardant treatment effect on the surface of the fabric on the other. The following commonly used mask standards all stipulate the combustion performance: GB 19083-2010, YY 0469 stipulates: the mask material should be made of non-flammable materials, and the mask burns for no more than 5s after leaving the flame. GB 2626 stipulates: if the product design is not flame retardant, it is necessary to provide explanatory information. If the product design is flame retardant, each part exposed to the flame will continue to burn for no more than 5s after the flame leaves. Medical Face Mask Flame Resistance test: Using a metal head mold and a burner, the mask wearer was simulated to pass through a high-temperature flame, and the flame retardant effect of the mask was detected. Testing instrument: Mask Flame Retardant Tester GT-RA06

Advantages of ultraviolet disinfection technology: The disinfection effect of ultraviolet disinfection technology on bacteria, viruses and other pathogens has been recognized worldwide, and it has unmatched sterilization efficiency of other technologies. The bactericidal effect of ultraviolet rays on bacteria and viruses is generally within one second. For traditional chlorine and ozone methods, it usually takes 20 to 50 minutes to reach the sterilization effect of ultraviolet rays. uv sterilization machine has high efficiency sterilization and broad spectrum, no secondary pollution, safe and reasonable design, safe and reliable operation. The operation and maintenance are simple and the cost is low. This Face Mask UV Sterilization Machine occupies a small area without noise. Continuous mass sterilization. There are many advantages such as wide application fields. Maintenance of ultraviolet sterilization machine: 1 Regular inspection to ensure the normal operation of the UV lamp. 2. After continuous use for 8000 hours or one year, the UV lamp should be replaced. When replacing a new lamp, first unplug the lamp power socket and take out the ultraviolet lamp. Be careful not to touch the quartz glass of the new lamp with your fingers, because the stain will affect the intensity of the light, and at the same time carefully put the lamp into the interior of the sterilizer.
