In the fast-paced life, manual brushing can no longer meet the growing “lazy” needs of lazy people. More and more people are starting to buy electric toothbrushes. Nowadays, the popularity of electric toothbrushes is getting higher and higher. According to new data, the annual sales of electric toothbrushes have reached 9 billion yuan! Many people want to buy an electric toothbrush but they don’t know how to choose one. They are worried that if they buy the wrong one, they may cause teeth-damaging problems like those found online. How to choose an electric toothbrush?
In addition to good cleaning ability, electric toothbrushes must also have good waterproof properties. Generally, electric toothbrushes have a layer insideElectronic waterproof and breathable membrane.
In the field of electronic appliances, Electronic waterproof and breathable membrane can well resist the influence of water, salt and other corrosive liquids. At the same time, the film that allows water vapor to pass through can prevent the occurrence of condensation to a large extent. By quickly achieving pressure balance inside and outside the shell, the stress on the shell sealing strip is reduced and easy to maintain.
Electronic waterproof and breathable membrane is a microporous membrane made by calendering, extrusion, biaxial stretching and other methods. The porosity can reach more than 85%, and the air can flow smoothly. The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above. Protect electronic instruments from becoming unusable due to moisture or water. Compared with other breathable filter materials, it has excellent air permeability.
PTFE technology has always been the core of the industry, playing a very important role in many fields such as biopharmaceuticals, equipment, food and beverages, semiconductor processes, communications, etc. The ability ranges from 0.1μm to 1μm, providing functional solutions such as fine filtration, removal of small bacteria and viruses, hydrophobic breathability, and sound transmission.
