It is the most scientific method to identify silk, the label, the material of the tire, the electrostatic combustion reaction, and other methods. Because China's silk is varietal and has various grades, it is difficult to distinguish the quality of the silk, especially the consumers who know little about silk. How to distinguish between the true and the false of the silk quilt? Mainly from the following aspects. Keywords: silk quilt, identification, scientific method It is the most scientific method to identify silk, the label, the material of the tire, the electrostatic combustion reaction, and other methods. Because China's silk is varietal and has various grades, it is difficult to distinguish the quality of the silk, especially the consumers who know little about silk. How to distinguish between the true and the false of the silk quilt? Mainly from the following aspects. a price and label At present, the silk is more than 100 yuan per kilogram according to the weight of its tires. This price includes the production cost, and also includes the normal and reasonable profit of the enterprise. If the price of silk quilt on the market is lower than this price, it is not inferior silk, or it is mixed with chemical fiber. Product name, factory name, product implementation standard and code, specification model, material composition, grade, net weight, etc. If the above content is not marked, the content of the label is incomplete or exaggerated, and consumers should be cautious when purchasing, in case they are deceived. Two quilt cover Look at the gusset's four corners or edges, if there is a zipper opening, if you can easily see the material of the tire, if the entire quilt is sewed tightly, when you propose to see the material of the tire is also the manufacturer Or when the merchant is smashed on the grounds of demolition, it is best not to buy the quilt. This quilt is likely to be "catty". Pull the zipper opening at the four corners or the edge of the quilt to see if the color of the silk is bright and uniform without fluorescence reflection. Whether the silk is long and elastic, if there is cotton wool, impurities, other chemical filaments or fluorescent reflection, please do not buy it. . Pull the zipper as far as possible to observe the larger area of ​​the tire, avoiding the fact that the four corners are silk and the middle is adulterated. Three electrostatic combustion reaction Firmly rub the exposed zipper opening for about one minute, then let it suck the small paper-sized pieces of paper, the distance is about 0.3mm to 1mm. If you can pick up the paper scraps, it means chemical fiber or a large amount of chemical fiber. Silk, pure silk does not produce static electricity. In the combustion reaction, the burning point of the silk is very low, and it is extinguished very quickly after burning. The smoke emerging from the burning is white, accompanied by the burning smell of protein from the burning feathers. The burnt ash is brittle and brittle, and the hand is pinched. Powdered; chemical fiber material burns black smoke with irritating odor, gray ash and hand squeezed, there is a clear difference between the two.
Gamicos, aims to provide customers more options when they want to buy a product to measure object's pressure. Differential Pressure Sensor, also called differential transmitter or differential transducer, is used to measure the difference between two pressures, It can be used to measure the differential pressure of different medium like water, air, oil, gas, etc. The working principle of the differential pressure sensor is that the measured pressure directly acts on the diaphragm of the sensor, so that the diaphragm produces a small displacement proportional to the water pressure, so that the resistance value of the sensor changes, and the electronic circuit is used to detect this change, and convert the output of a standard measurement signal corresponding to the pressure.
