Water purifiers can be divided into two categories: progressive water purifiers and self-cleaning water purifiers according to pipeline design levels. The traditional water purifier is a gradually tightening water purifier. Its internal pipeline is designed to loosen the filter element in the front and tighten it in the rear. It is composed of PP melt-blown filter element, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and post-activated carbon. Generally, It is composed of these 5 levels connected end to end. 3M water purifier's patented filter membrane has a unique "progressively tightening" internal structure, with outer looseness and inner tightness progressively increasing layer by layer. It has strong dirt-holding capacity and the BlackMagic black miracle activated carbon rod, whose filtration and adsorption performance far exceeds similar products. Let us introduce to you the filtration principle of 3M water purifier and other related knowledge
The filtration principle of 3M water purifier
1. Please open the water inlet valve when using the product for the first time. Remove the air from the system and close the faucet after the water flow is stable. Observe whether there is any leakage in the system. If there is leakage, immediately reinstall the leakage point.
2. The system should be drained for 5 minutes before use.
3. If the water purification system is not used for a long time, please close the water inlet valve to prevent accidents. If it is resumed after a long period of inactivity, please open the faucet and drain it for 3-5 minutes before using it again.
4. The service life of the water purifier filter element is related to the water source water quality, total water consumption, etc. If the outlet water flow becomes smaller or the outlet water has a peculiar smell, please replace the filter element in time.
3M water purifier patent
The product has passed the testing of the international authoritative organization NSF and the National Sanitation Foundation, and has obtained the gold medal mark of the American Water Quality Association and the water-related certification of the Chinese Ministry of Health; advanced composite membrane Pre-activated activated carbon technology effectively removes chemical substances and heavy metals, odors, chlorine, bacteria, spore cysts, VOC (volatile organic compounds), MTBE carcinogens (such as methyl tert-butyl ether, etc.), scale and impurities.
The historical development of 3M water purifier:
In 1902, five young people founded a mining company in Two Harbors, Minnesota, USA. At the beginning, they only mined ore sand, and soon discovered that Mineral sand has better development prospects, that is, the manufacture of sandpaper has begun. This is the beginning of 3M.
For a century, 3M has been committed to expanding the limits of science and technology, constantly improving, combining and creating, bringing more new products to the market, ensuring that we have an average of 500 new products that are practical, reliable and tailored to different customer needs every year. product.
In 1910, the company moved to St. Paul, Minnesota, where the company is now headquartered, and launched its first vacation product, Three-M-ite, in 1914. p>
In 1921, the world's first waterproof abrasive sandpaper, Wetordry 3M, was born and patented, ushering in a new era for industrial grinding.
In 1924, 3M began formal product research and development. Thereafter, Scotch said that ScotchAе pours to defend Scotch ants┗缱煗 Swim to defend ⒖ a little bit of feed pool ǖ which grasshopper defends but green captive waste crop wave suitable feed S around the 1980 postit note paper, let the information Communication has been revolutionized. The emergence of endless innovative products confirms every progress of 3M. Various products under well-known brands such as Postit, Scotchgard, Scotch, Thinsulate, Filtrete, Scotch, Brite, Nomad, Dyneon, and Nexcare are promoted to the world, influencing and changing people's lifestyles and habits.
The above is what the editor has summarized for you about the filtration principles and patents of 3M water purifiers, and the historical development of 3M water purifiers.
