First of all, from the aspect of the raw materials and molding of products, the PU line is made of polyurethane A and B. The two materials are stirred and evenly put into the mold and then foamed. (Polyurethane A material is also called white material, B material is also Called black material); PS line is called molded polystyrene foam plastic, PS particles foaming agent (pentane, etc.) chemical reaction, so that the PS particles swell, and then placed in a different mold heating foam molding .
Then from the use of the details of the difference between the PS line and PU line, PS line is mainly used in the TV background wall, framed window frame lines, baseboard, frame, the main advantage is that the line hardness is good; PU lines are mainly used The place is at the corner of the wall, the lights are with lines, the ceiling is at the top, the lines of the various shapes of the wall are more commonly used, and there are various ornaments for various indoor and outdoor applications. The main advantage is that the surface is suitable for various treatments, the surface can be sprayed with any kind of paint, and the interior style is more uniform. It is more natural, the color and shape are not too rigid, the performance is relatively flexible, and of course, the biggest advantage is that PU lines are suitable for all kinds of circular arc type, more soft lines can be directly on the scene to do arbitrary modeling, very convenient. At the same time, the weight of the PU line is very light, which is very convenient for transportation and installation.
From the aspect of environmental protection, PU lines are placed under the open air when they are not treated on the surface, and they are exposed to sunlight. After a certain period of time, the PU products will turn into mud and integrate with the soil, and it will be non-toxic and harmless. Since the main raw material is the same as our usual plastic bags and disposable thermal insulation boxes, the environmental performance can be imagined. In terms of service life, if the PU product is not surface-treated, the surface will be oxidized and naturally yellowed. Then what if we don't want him to oxidize? The method is still used, that is, to do anti-oxidation paint treatment on the surface, use it to protect the green paint will play a protective role, with 20 to 50 years is no problem (we ourselves used the house for decades The decoration should also be eliminated.) The PS line is the same as the plastic bag.
From the price comparison, PS line will be much cheaper than the PU line price, first of all because of the different raw materials, followed by some domestic manufacturers also have to take recycled materials to re-create the phenomenon of the product, while the PU line but the AB material mixed foam molding, will Can not be recycled production, because this particular property owners friends will be more comfortable using PU lines. At the same time, because of the difference in the foaming process, the PS lines are directly formed by machine stretching, and the PU lines need to be fixed after being poured into the mold. At the same time, a large amount of manual work is required in the later period, which determines the cost.
"Good reputation", as a well-known high-end PU line manufacturer in China, is a large-scale factory integrating design, production, processing, warehousing and business. The PU decorative lines designed and produced can fully show the gorgeous and elegant European design. The noble style. Products exported to Europe, North America, Australia, Southeast Asia and other regions for more than ten years, by the major international buyers, building materials distributors, decorative design companies and owners of love and recognition, is now the provincial and municipal agents dealer hot recruitment!

Above-mentioned equipment was successfully developed by Changchun Gold Research Institute in 1998. It has possessed three patents and five monopolized technologies. Desorption solution does not contain sodium cyanide, it can reduce the grade of barren carbon down to 100g/t. The key technology of this equipment is that it can ensure the balance of metal quantity, and avoids gold- accumulating and gold- floating from the equipment, ensures the technological index steady and low cost of it. The content about technological advantages has been broadcasted by Xing Huo Science and Technology of CCTV. This technology was appointed as the energy-saving technology of gold production by National Development and Reform Committee in 2006, and was also appointed as standard equipment in the industry by National Development and Reform Committee in 2007, it passed the technique identifying in 2003, and won the second award of science and technology of China National gold Association, the entire technical level is advanced at home. This equipment has won three patent rights of China. The patent numbers of it are separately: 01241537.5 01241538.5 200620029209.1
