For most people, they are no stranger to these products, especially the decline in air quality in recent years, which has made the originally polluted city air even worse, so in order to improve the quality of life and get fresh air, a dust-proof screen It is indispensable. At the same time, many screen manufacturers have introduced screens to prevent dust particles, and have been favored by many consumers. Of course, it has also attracted many doubts. So can dust screens really be dustproof ? Let's take a look together with the editor, I hope to help you.
Can dust screens really be dustproof?
1. Nowadays, the net yarns sold in the market use polyester mesh and nuclear pore membrane. The former is a kind of filter material for production inspection, while the latter is a new type of microporous filter membrane developed in the 1970s. Therefore, dust-proof screens can block atmospheric pollution and PM2.5 to a certain extent, and maintain the freshness of indoor air.
2. However, consumers should not be too blind to believe in the dustproof effect of mesh, because some businesses will deliberately exaggerate the facts in order to attract users. For example, the barrier rate is greater than 98%, the ventilation rate can reach 0.9 cubic meters, etc. Some names are exaggerated.
3. It is believed that many users have found that the dustproof function of this type of product is relative, and it cannot completely isolate the dust of some smaller particles in the gas. In addition, it is not conducive to indoor ventilation and ventilation. Very good, so when buying dust screens, these shortcomings must be considered.
Tips for buying dust-proof screens
1. Look at the mesh
Net yarn is also divided into imported and domestic. Generally speaking, the former one is made of chemical fiber, and the latter one is made of glass fiber, and some are made of plastic material. When selecting, try to use imported mesh yarn, because It can pass tens of thousands of push-pull friction without deformation, and also depends on whether the yarn hole is uniform, or touch the net yarn by hand to see if its feel is slightly scratched.
2. The structure of screen
In fact, the structure of the screen window is directly related to the price of the product. The editor recommends friends to use aluminum alloy plates, because the plastic is easily deformed under the sun and has a short service life. In addition, it can also be pressed by hand Move or shake the screen window to feel the hardness of the profile, which is not soft.
3. Bearings for screens
Whether this part is of high quality will directly affect the efficiency of operation. Generally speaking, it is better to use imported fully enclosed silent bearings, mainly because the open bearings that should be made in China are easy to enter the dust, and you can also observe whether they are equipped with guide rail positioning rods. If it is not, the strong wind blows the yarn and the mosquitoes will enter.
Conclusion: The article is an analysis of the knowledge about whether dust-proof screens can really be dust-proof. I believe that many people in need have a better understanding of whether dust-proof screens can really be dust-proof. Of course if you have better suggestions and ideas, please feel free to consult Editor.
