Spring is accompanied by the breeze and slowly comes to us. The year is spring, are you already ready to renovate your own home? The problems that need to be considered for decoration are very wide. If you want to balance the needs of the whole family, the preparations in the early stage are indispensable. Life home Xiaobian Chenchen has prepared the most comprehensive and practical decoration information for you here, hoping to make all the small homes warm and comfortable!
Handmade carpets are made by hand, mostly made of pure wool and silk. There are more than a dozen processes including pattern design, color matching, dyeing, warping, hand knotting, flat blanket, blanket, washing blanket, cutting, trimming, etc. Processed and made. It can harmoniously combine dozens of colors, and the tight and delicate carpet surface can extend the life of the carpet to hundreds of years. Such a cumbersome process makes it necessary to make a blanket from months to a year or two.
Handmade carpets can be divided into Persian carpets, European French carpets, Tibetan carpets, and traditional Beijing carpets. Persian rugs are woven with wool and mulberry silk. The patterns are densely coloured and have a strong western style. The overall temperament is graceful and luxurious. European-style French rugs are also made of pure wool and mulberry silk. The pattern is gorgeous and romantic. It has the effect of Western oil painting and has a strong European style. The patterns of Tibetan carpets are woven from mulberry silk. The color is mainly beige, with a small amount of gold, pink and red. The pattern is simple and clear, fresh and elegant, and the mystery is simple and simple. The traditional Beijing-style carpet is rich in Chinese culture and has a strong national color.
The main points of buying handmade carpets
First, look at the raw materials. Superior wool and silk are the guarantee of quality.
Second, look at the production process. The technology for handcrafting carpets around the world is also different. First check whether the back of the carpet is firm and tight. The traditional knotting methods such as 8-button buckle and Turkish buckle are the best guarantees for making the carpet surface firm and durable. See if it is spinning, dyeing, knotting, flat, The process of filming, washing, casting, and finishing, so that the hand-made carpet woven is thick and firm, and the pattern has a three-dimensional embossed appearance.
Third, look at the carpet to deal with the details. The average woven carpet has only 10 colors, and there is no gradient color in the same pattern, which looks more blunt. But even if the handmade carpet is woven with a peach, you can use more than a dozen colors, even dozens of colors to polish, this is the woven carpet can not reach anyway, this is the artistic value of handmade carpet.
Fourth, look at the color style.
Fifth, see after-sales service. High-value handmade carpets require professional maintenance.
1. Product introduction
Coal-based columnar net gas Activated Carbon is cylindrical, tasteless non-toxic; as high quality anthracite the raw material, by process of crushing, mixing, extrusion, molding, drying, carbonization, activation and made. It has reasonable pore structure, good adsorption properties, high mechanical strength, able to withstand the high temperature, high pressure and not easily broken, easy to regenerate, and low cost characteristics. It is widely used in sewage treatment, gas treatment, solvent recovery, desulfurization and denitrification, nitrogen making machine, air separation equipment, paint shop and other fields.
2. Application
a.Coal columnar net gas activated carbon used for purification, such as chemical raw materials, pharmaceutical chemical synthesis gas, industrial gas, nitrogen, chlorine, hydrogen chloride, ethylene hydrocarbons, ozone, ethane, butane, cracking gas, carbon dioxide and hydrogen used in beverage; atomic facilities exhaust inert gas and remove the pollutants; also separate and purify mixed gas. It also can be used for gas masks and protective equipment disinfection and filtration.
b.Coal columnar net gas activated carbon is mainly suitable for industrial waste treatment, such as waste gas power plant, chemical plant gas, coking plant, smelting plant, oil plant. Coal columnar net gas activated carbon rely on the good adsorption capacity, developed gap, high iodine value can make a cleaning purpose.
3. Adsorption purification principle and process
The physical properties of coal-based activated carbon introduction: it is cylindrical black particles; the physical, chemical properties analysis of carbon is a porous carbon, the highly developed pore structure makes it has large surface area, so it is easy to full contact with toxic and harmful gases in the air (and harmful impurities), so this highly developed capillary and pore structure formed a powerful adsorption force field, which gives the unique adsorption properties of activated carbon.
Adsorption: the organic waste gas passes through the filter removed the solid particulate material, from the upper to the lower into the adsorption tank. The organic matter is captured, absorbed and concentrated by the activated carbon, and the purified air is discharged from the lower part of the tank through the main fan into the atmosphere.
Stop: when activated carbon adsorption reached saturation,it stops to inhalation waste gas; and then blowing up into the steam through the activated carbon bed, which expelled the organic matter from the activated carbon, and the subsequent restoration of desorption, activated carbon activity is recycled.
Hot air drying and cooling: the activated carbon layer after desorption remains 80%-90% steam condensate which can in reducing carbon layer activity; therefore using the hot air to dry, close the steam valve, and then through the air cooling at 25 DEG C, activated carbon can be recovered into the circulation.
