How To Use Infrared Thermometer Correctly Before infrared thermometer is used to measure, it is important to understand the advantages, limitations and correct use of these thermometers. Improper use of Non-Contact Infrared Thermometer may result in incorrect temperature measurement. Limitations of Non-Contact Infrared Thermometer The use and location of Non-Contact Infrared Thermometer may affect the measurement (for example, hood, environment, forehead position). The close distance required to measure a person's temperature correctly represents the risk of disease transmission between the person using the device and the person being assessed. Proper use Non-Contact Infrared Thermometer The person using the equipment should strictly follow the manufacturer's guidelines and instructions to use the specific Non-Contact Infrared Thermometer. The manufacturer's instructions for use usually include the following information and recommendations for proper use: Prepare the Environment and Non Contact Infrared Thermometer The use environment may

What are CE masks? CE marked masks are disposable respirators approved by the European Economic Area for safety, health and environmental protection standards. Much like NIOSH grades respirators as either N95, N99 or N100 according to its efficiency rating, CE grades their masks as either FFP1, FFP2, or FFP3. European Standard EN 149 defines the following classes of [filtering face pieces": FFP1 filters at least 80% of particles; FFP2 filters at least 94% of particles; FFP3 filters at least 99% of particles. More information We offer standard cone masks, flat fold masks, as well as our new flanged edge style mask with CE marking. See our introductory articles on N95 Masks and disposable respirators, KN95 masks in general.

What are disposable respirators? Disposable respirators are the general industry term for face masks containing filter material to block airborne particles from passing through. These masks are designed to be thrown away after use.Disposable Respirators protect workers from inhaling particles created during grinding, crushing, drilling, sanding, mixing and cleaning operations. In North America, the National Institute for Occopucation Safety and Health (NIOSH) approves disposable respirators and they are rated N95, N99 and N100 according to their filtration capability. The N95 is by far the most popular disposable respirator for use in the United States. Europe and other parts of the world have other approvals, the most common being the CE marking. CE masks have similar qualities to N95 Masks. In China,the most popular being the KN95 marking. Both n95 masks and KN95 masks are basically the same from the technical requirements to the test m

What kind of masks do people generally wear? In order to prevent the coronavirus pandemic, the masks worn by people are generally divided into cotton yarn masks, surgical masks, kn95 masks, and n95 masks. Cotton yarn mask- It can prevent some viruses from invading, but it has poor adhesion to human face and low anti-virus efficiency. Surgical mask- divided into 3 layers, the outer layer blocks water, the middle layer blocks 5μm particles in the air> 90%, the inner layer absorbs moisture. N95 mask- N95 is certified by the american occupational safety and health institute. N refers to non-oily particulate matter, 95 refers to the filtration rate of 95% under the standard detection conditions, and has good adhesion. Kn95 mask- KN95 level is one of the levels stipulated in chinese standard gb2626-2006. Both n95 and kn95 are basically the same from the technical requirements to the test methods, but they belong to different national standards. Here, you should note that n95 mask or kn95 mask is not a specific brand product name, as long as it meets the n95 (or kn95) standard, and the product that passed the review can be called "n95 (kn95) mask".

Why distinguish the Differences Between Medical Protective Masks And Ordinary Masks? Medical protective masks should have the function of effectively blocking liquid splashing, and have high hygienic requirements. Due to the possibility of splashing blood or infectious body fluids during surgery, such splashing has a certain pressure and is not a general liquid infiltration. The ability of the mask material to block pressured fluids should be relatively high. Protect medical personnel. Therefore, in the standard of medical protective masks, a special detection method is used to test the liquid barrier performance of such products, and the protective masks used in general industrial environments do not need to have such special requirements, and there is no such regulations. In addition, medical protective masks are not allowed to have an exhalation valve. This is because when the medical protective mask is allowed to be used as a surgical mask, if a mask with an exhalation valve is worn, the microorganisms carried in the exhalation will be directly discharged out of the mask, posing a threat to the patient undergoing surgery. Many industrial protective masks have an exhalation valve design. In order to isolate viruses, dust, and air pollution, people usually wear disposable masks. For more information about disposable masks, please read related articles.

The utility model discloses a degradable food packaging plastic wrap for packaging fruits and vegetables. The main point of the technical solution is that the plastic wrap includes a base layer, an intermediate layer and an upper layer. The base layer is an inner layer directly in contact with fruits and vegetables. The upper layer is an outer layer in contact with outside air after wrapping fruits and vegetables with plastic wrap. The base layer and the intermediate layer are connected by a first adhesive layer, and the intermediate layer and the upper layer are connected by a second adhesive layer. The base layer is a polyethylene layer, the middle layer is a nylon layer, the upper layer is a polyvinyl chloride layer, the first adhesive layer uses PA glue, and the second adhesive layer uses PE glue. The base layer of the plastic wrap is made of polyethylene suitable for food contact, which is less harmful to food and guarantees the safety of food. At the same time, the polyvinyl chloride layer of PVC Cling Film uses polyvinyl chloride doped with starch, which makes the plastic wrap in use After finishing, the fresh-keeping can be used up, and the degradation of the fresh-keeping film can be realized by microorganisms in the soil.

Beijing - in the new round of coronavirus epidemic (covid-19), China will establish a new cross-border e-commerce pilot area, support processing trade, hold online Canton Fair, and stabilize foreign trade and investment, according to the executive meeting of the State Council. The meeting was presided over by Premier Li Keqiang, who decided to continue to implement preferential tax policies for inclusive financial services and small loan companies to help small and micro businesses, individual businesses and farmers through difficulties. The accelerated spread of the epidemic has had an impact on the global economy and international trade and investment. The meeting said that governments at all levels must continue to implement the policy of opening up to the outside world and take measures to stabilize foreign trade and investment so as to reduce the impact of the epidemic on the national economy, especially the employment market. In addition to the 59 cross-border e-commerce pilot areas that have been set up, China will build 46 new pilot areas to exempt value-added tax and consumption tax on retail exports in all pilot areas, and encourage enterprises to build and share overseas warehouses. The meeting stressed that processing trade accounts for a quarter of the country's foreign trade, and it is necessary to increase efforts to promote the development of processing tr

At present, with the prevalence of coronavirus, people are sensitive to the change of body temperature. What is the normal temperature range of human body?measurer needs to know the human body temperature range when measuring body temperature. There are many ways to measure body temperature today, such as traditional thermometers, non-contact infrared thermometer, medical non-contact infrared thermometerm etc. So what should you pay attention to when measuring the body temperature of an infrared thermometer? What is the human body temperature range? First, we need to know the range of human body temperature. Under normal circumstances, the normal body temperature of children aged 0-2 is 36.4-28 degrees; for children aged 3-10, the normal temperature is between 36.1-37.8 degrees; for persons aged 11-65, the normal temperature is 25.9 -37.6 degrees; for the elderly over 65 years old, the normal body temperature is between 25.8-37.5 degrees. It can be seen that as the age increases, the body temperature of the human body will decrease. However, the above is only the average temperature value of the human body and cannot represent everyone. Therefore, when measuring body temperature, it is necessary to analyze the specific situation. Everyone has a certain deviation.

What is KN95 masks ? KN95 mask is a mask that meets the requirements of China's GB2626 standard, GB means the national standard. The standard is the filtration efficiency of non-oily particulate matter ≥95%. N95 masks are NIOSH certified by the United States, and the standard is also the filtration efficiency of non-oily particulate matter ≥95%. KN95 and N95 masks need to be worn correctly: Before wearing the KN95 masks and N95 masks, you need to wash your hands before wearing them. The light color is inside and the hard strip is on the top. Don't wear it wrong, it will not protect you. Time to change the mask: If you use KN95 or N95 masks normally, you can choose to replace one within 4 hours. Don't change it for too long, because if it is too long, the mask will lose its function. Special circumstances require timely replacement: In so

N95 medical mask is one of 9 anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health). "N" means not suitable for oily particles (oil fumes produced by cooking are oily particles, and the droplets generated by people talking or coughing are not oily); "95" refers to filtering under the test conditions specified in the NIOSH The efficiency reaches 95%. N95 is not a specific product name. As long as it conforms to the N95 standard, and products that pass the NIOSH review can be called "N95 masks." is one of 9 anti-particulate masks certified by NIOSH (National Institute of Occupational Safety and Health).

We usually say that packaging printing, including color box printing, carton printing, label printing, bag printing, bottle printing, different products have the most suitable printing method. Flexographic, offset, gravure and screen printing are among the world's four most popular printing methods, each with its own characteristics. Flexo printing has evolved from letterpress printing, a direct printing method known as flexographic printing due to the use of elastic, raised image plates. The flexographic plate is glued to the plate cylinder and the plate is supplied by an engraved metal anilox roll. Offset printing is a kind of lithography. It is very simple to say that offset printing is the printing method of transferring the graphic on the printing plate to the printing substrate by means of rubber (blank), that is, there are three rollers (printing plate, blanket, embossing). The lithographic method is called offset printing in the south of China. The gravure printing ink is full and full of three-dimensional, the graphic has a convexity, and the layers are rich, the lines are clear, the high quality printing plate has a long service life, and is suitable for mass printing. Gravure can print extremely thin materials such as plastic films.

Stretch wrapping film knowledge you want to know Using the Wrapping Film for product packaging, the price of plastic packaging film can effectively reduce the cost of use. stretch wrap 18 x 1500 The wrapping film wrapped with plastic is only about 15% of the original wooden box packaging, about 35% of the heat shrinkable film, and about 50% of the carton packaging. . At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging grade. Stretch film is divided into mechanical film and artificial film. The stretched form of plastic packaging film of tray mechanical packaging (also called machine stretch film and clear stretch film) has direct stretching and pre-stretching. 1. The stretched film shrinks too much during the stretching process and does not reach the required width of the product; 2. The stretch film is too hot to retract during the secondary compounding process, which exceeds the standard requirements and does not reach the required width of the product. The material of the stretched film is an amorphous polymer which, when subjected to a tensile force greater than the yield strength in a certain temperature range, produces plastic elongation deformation, and polymer structural units (segments, macromolecules and crystallites) during the deformation process. Orientation begins due to stretching. As the degree of orientation increases, the force between the macromolecules increases, causing the viscosity of the polymer to increase and tend to harden, and the deformation tends to be stable and no longer develops. This phenomenon is called "stress hardening". The
