Qualified stone selection method In the home decoration, the pursuit of high-end decorative materials has become a new fashion, and in many materials, the use of stone is more common. Then, when buying stone, you should look at those indicators and buy good stone. Generally, when buying stone, the first thing to see is the surface of the stone, then look at the color process, etc. The following is a specific introduction. Look at the surface The color of the surface of the stone is an important indicator for evaluating the quality of the stone. The good natural stone decoration plate depends on the quality and processing technology of the block material. The high-quality stone surface pattern color does not contain too much variegated color and uniform color. The situation of faintness and faintness, and the quality of the stone after processing will have many "defects" that cannot be covered. If the processing technology and process are not closed, the finished product will have warpage, dents, stains, stains, missing corners, cracks, color lines, pits and other phenomena, so it can't be the same as the top grade. According to experts who specialize in processing and selling imported stone, the high-quality natural stone plate cutting edge is neat and tidy, the surface is smooth and bright, and the hand touch is not rough. At the same time, in the selection of stone, in addition to pay attention to the choice of stone surface color pattern, gloss and appearance quality and other decorative properties, should also consider the stone's compressive strength, flexural strength, durability, frost resistance, wear resistance Physical and chemical properties such as hardness. Look at color, craft, leveling Color, good natural stone decorative board depends on the quality and processing technology of the block. The quality of the surface of the high-quality stone does not contain too much variegated color, uniform color of the cloth, and there is no faint and faint situation. However, the quality of the stone will have many unrecognized "defects" after processing, so the stone surface The tone of the pattern is an important indicator for evaluating the quality of the stone. Process, the surface of the stone in the process of cutting, sawing, grinding, polishing and other processes, its beautiful "face" can be seen. If the processing technology and process are not closed, the finished product will be warped, sunken, stained, stained, missing corners, cracks, stains, color lines, pits, etc. ". Unevenness, the whole stone is not flat, the arched arch plate and the small axe plate on one side are also secondary plates. After the paving, there will be uneven surface and uneven seams, especially in the standing. During the surface decoration process, the irregular decorative surface line type will affect the overall decorative effect. According to Ms. Zhang Wenjia, the general manager of Beijing Kaiyue Company, which specializes in processing and selling imported stone, the high-quality natural stone plate has neat and sleek edges, smooth surface and high brightness, and there is no rough feeling by hand. At the same time, Mr. Zhang also mentioned that in the selection of stone, in addition to pay attention to the choice of stone surface color pattern, gloss and appearance quality and other decorative properties, should also consider the stone's compressive strength, flexural strength, durability, resistance Physical and chemical properties such as freezeability, wear resistance and hardness. Choose the right color Under normal circumstances, the living room and other large areas of "public space" are best to use white, beige and other light-colored products, because light colors and all kinds of furniture can achieve a perfect combination, to show more personality to the fickle The stage; the dark color will make the surrounding environment appear bright, but the large area of ​​use or mismatch will produce a sense of oppression, such as some small-area countertops and other decorative decorations, preferably with dark products, so that The effect of the finishing touch, does not make people feel light. Therefore, although the stone has a good decorative function, it should be considered in harmony with the surrounding environment in the process of use. Especially when combining multiple colors, not only must it coordinate itself, but also coordinate with the surrounding natural color. Otherwise, The situation of "wearing a suit and wearing shoes" will appear.
Coal Activated Carbon For Recycling Of Solvents
Using high quality coal as raw
material for solvent recovery, coal is mainly used in the recovery of
benzene, toluene, ether, alcohols, gasoline, three, methyl chloride,
organic solvents and other hydrocarbons, as well as the vapor recovery
of hydrocarbon compounds.
Use: Used in the seperation and recycling of aethers,
ketons, alcohols, tetrahydrofuran, methylene dichloride,
trichloromethane, trichloroethylene, chlorinated polyvinyl chloride,
carbon bisulfide, benzene, gasoline etc.
