Know More About Three Kinds Face Mask Disposable mask The main material is non-woven fabric, and the filtering effect is slightly higher than that of cotton masks. Medical masks that do not have the words "protection" or "surgical" on the name are ordinary-level disposable medical masks. This level of masks does not require blood blocking or adhesion requirements. For very small particles, disposable The protective effect of masks is not as good as that of protective masks. Therefore, it is only used for the general medical environment. But it can be used for larger particles, such as dust, pollen, fly floc. Medical-surgical mask Medical-surgical masks are used for the protection of droplet isolation. Medical-surgical masks are required to be worn in infectious disease departments and fever clinics. It is divided into 3 layers, the outer layer has a water blocking effect, which can prevent the droplets from entering the mask to the inside; the middle laye...

Sublimation Transfer Paper Printing With High-Quality Printing

Sublimation Transfer Paper Printing With High-Quality Printing In order to determine whether you can imprint a product with a wash-fast, scratch-resistant, full-color sublimation image, you'll need to check three items: First, is the decoration area polyester-based? Sublimation printing is reliant on polyester's unique molecular structure (e.g. its ability to bond with the gassed ink dyes). You can not sublimate to cotton, nylon, vinyl, wood, leather, etc. Second, will the product hold up to the optimal temperatures (up to 400° F) and pressure required for the dye sublimation process? Lastly, is the color of the product light enough to take an image? Because this is a dye technology, the color of a sublimation product's decoration surface can affect the final colors of your graphic. True white works best, but you can still decorate lighter colored products such as t-shirts or sand-colored stone tiles while achieving 70-80% of the printer's available color gamut. ...

¿Puede la máscara con válvula de respiración ser antivirus?

¿Puede la máscara con válvula de respiración ser antivirus?      Un médico dijo en la plataforma SNS que las máscaras de válvula respiratoria no pueden usarse para prevenir infecciones virales. La razón que dio fue: "Es difícil alcanzar el nivel de protección N95 en la válvula de respiración". Esto suena razonable. Además, muchas personas ven fotos de médicos con máscaras sin válvulas respiratorias. Es natural pensar que es más seguro sin válvulas de respiración. Es una pena que esta afirmación parezca razonable, pero de hecho no tiene una base científica.     En primer lugar, no importa si se trata de la FDA de EE. UU., Los CDC o el NIOSH, la definición de máscaras N95 nunca ha excluido la "válvula de respiración". En la página de NIOSH de máscaras N95 previamente certificadas, podemos ver una gran cantidad de máscaras con válvulas de respiración. Aquí solo tomemos algunos productos de 3M como ejemplo.     En segundo lugar, los elementos de...

Fascinating Sublimation By Sublimation Paper

Fascinating Sublimation By Sublimation Paper   Sublimation is the fascinating process by which dye sublimation ink is transferred onto heat transfer paper and later onto something else via a printer. This doesn't sound terribly exciting until you begin to understand what makes sublimation different from what inkjet type printing does. Sublimation ink is a gas that is transformed into a solid without ever entering into a liquid state. Once it's on the sublimation transfer paper and applied to a properly treated product, the ink actually bonds to the molecules it's being applied to, making a perfect image that cannot be removed by any method.      Sublimation is one of the many ways that companies take a photograph and transfer it to a mug or a t-shirt. Sublimation isn't the only way to transfer images and in some cases, its not even the ideal way. But in many cases, particularly when it comes to photography, sublimation printing is the best way.     ...

Do You Know The Right Way to Use The Heat Press Machine?        A heat press is a machine that is used to transfer designs onto everything from T-shirts to hats to plates. To bond a design to an item, the machine uses high heat and pressure. Typically, heat press machine has to be heated to a temperature of at least 375 degrees. Before you begin transferring a decal to an item, allow the heat press to warm to the appropriate temperature --- you should be able to find this temperature in the owner's manual that came with your heat press.     Things You'll Need     Heat press     Decal Printable item Instructions 1, Plugin your heat-press, close the top of it, turn on the machine and set the temperature dial to the appropriate level. If you're not sure what the correct temperature is, consult your owner's manual. Allow the heat press to warm to the correct level before you use it. 2, Open the heat press and place your printa...

When should you wear a face mask?

When should you wear a face mask? The World Health Organization (WHO)Trusted Source recommends using surgical masks only if you: have a fever, cough, or other respiratory symptoms are well but caring for someone with respiratory illness — in this case, wear a mask when you’re within 6 feet or closer to the person who is ill Although a surgical mask helps trap larger respiratory droplets, it can't protect you from contracting the novel coronavirus, which is known as SARS-CoV-2. That’s because of surgical masks : 1. don't filter out smaller airborne particles 2.don't fit snugly on your face, so airborne particles can leak in through the sides of the mask Some studies have failed to show that surgical masks effectively prevent exposure to infectious diseases in the community or public settings. At present, the Centers for Disease Control and Prevention (CDC)Trusted Source doesn’t recommend that the general public wear surgical masks or N95 respirators to prot...

What's the Difference Between N95, KN95, and FFP2    When you search for the N95 respirators, there are many respirators such as KN95, FFP2, and KF94 that appeared in the same breath. What’s different between these respirators of different letters?    Actually, both the N95 face mask, KN95 face mask, FFP2 respirators have almost the same filtration efficiency, it means that KN95, FFP2, and KF94 are as effective as the N95 respirator mask. The main difference between these respirators is that they are tested by different nations.    The N95 mask has a full name of NIOSH-certified N95 respirator, which means these respirators are tested of 95% filtration and certified by the U.S. National Institute of Occupational Safety and Health (NIOSH).
