Granite is a common decorative stone. In the past, the stone construction process mainly used the wet sticking method to operate. The wet sticking method mainly removes floating sand and debris from the working surface, lays the cement mortar on the ground, directly lays the brick on the top, and leveles with a skin hammer. Now use the dry-laid method to wet the base layer, remove the floating sand, debris, wipe the joint layer, and soak the bricks. Use one to three dry hard cement mortar, level the paving according to the horizontal line, and flatten the water-soaked brick. Put it on a semi-dry cement and beat it with a sponge. Squeeze out the bubbles in the cement and take the brick below. Apply a thin pure cement slurry on the back of the brick to smooth the tile. Use this layer of cement slurry. The base tile and the dry hard cement mortar base are completely bonded together. This paper analyzes the dry-grown granite and wet-pain granite processes and the shortcomings of the new dry-hanging method. Dry hanging granite is compared with traditional wet-laid granite; (1) Different mechanical systems: It can be directly used for the outer wall of high-rise buildings. The dry-hanging granite can be directly fixed directly with the hooks. It can be a separate force on each wall: wet-laid granite can only be used in buildings with low height. The use of the wall surface mainly relies on the connection of cement slurry and steel wire. (2) Wet-attached granite is unstable, and it is easy to peel off and shell after the summer and winter heat and cold. (3) Cement is prone to the quality problems of the face and efflorescence of granite walls during the process of passing humid air and hydration heat. Dry-hanging granite, compared with the glass curtain wall, has a coated glass on the surface of the glass curtain wall, which is easy to reflect, causing environmental pollution; and compared with dry-hanging granite, the glass curtain wall has poor heat insulation and insulation capacity, which determines the high-rise or The super high-rise is decorated with dry hanging granite materials. At present, although dry-hanging granite has obvious advantages, there are still some problems to be solved. Firstly, the transmission of force by dry-hanging granite needs to be transmitted to the concrete wall surface by means of expansion bolts, which is prefabricated with traditional iron glass walls. The way of the force is different. Secondly, the dry-hanging granite transmits the weight of the granite to the concrete wall and the expansion bolt by using the stainless steel connecting piece, which easily causes the deformation of the stainless steel connecting piece; then, the dry hanging granite realizes the connection of the connecting piece through the pin The key to the construction of granite stone wall lies in the quality of the perforation, and its quality is related to the material of the granite itself. The quality and stress of granite is greatly related to the control of the seam of stone curtain wall; finally, the compatibility of granite bonding and the control of the quality of waterproof sealing rubber.

UPE plastic,full name UHMWPE (ultra high molecular weight polyethylene) is a kind of thermoplastic engineering plastic with excellent properties of linear structure, with a molecular weight of more than 1.5 million.mainly have ESD UPE SHEET,CONDUCTIVE UPE.
Small density, good wear resistance, self - lubricity, impact resistance, corrosion resistance and so on.
Advantages:
1. Average molecular weight about 5,000,000 to 9,000,000;
2.The best abrasive assistance of all plastics , which 4 times higher than that of nylon 66 or teflon and 6 times higher than that of carbon steel;
3.Extremely high impact stength ,which is twice as high as PC ,5 times as high as ABS,it also retaines high toughness at liquid nitrogen temperature (-196'C);
4.Low friction coefficient ,lubricity is equal to that of Teflon ;
5.The best impact energy absorption value of all plastics ,with very good sound reduction effect ;
6.High chemical stability ,capable of resisting various types of corrosion and organic media within certain temperature and concentration range;
7.Strong adhensive resistance which is only second to Teflon;
8.UHMW-PE Plastic is safe , healthful and non-toxic and be can used in contact with food and drugs ;
9.Low density than any other thermoplastic ;
10.Excellent electrical insulation and static resistance ,good resistance to high energy radiation;
11.Moderate mechanical strength,stiffness and creep-resistant property'
12.Outstanding machining property ,very low water absorption .
Deficiencies:
Compared with other engineering plastics, UHMW-PE Plastic is resistant to heat resistance, stiffness and hardness, but can be improved by means of "filling" and "crosslinking".
From the point ofheat resistance, the melting point of UHMW-PE Plastic is approximately the same (136 ℃) and ordinary polyethylene, but because of its big molecular weight, melt viscosity high, so the processing difficulty is big.
Applications:
Papermaking industry : suction box boards ,scrapper,molding plate ,beating ,gear .
Mining industry : charging barrel ,abrasive and adhensive -resistant back lining for warehouses.
Chemical industry : acid pump ,fliter plate , worm gear ,bearing .
Food industry :packing machinery parts ,bottle guide ,screw .wear plate ,slide away ,stud weld ,roller and other transmission parts.
Tenxile industry : buffer board
Food processing industry : chopping block ,refrigerating plant
Wharf:anti-collision board
Specification: the thickness of UHMW-PE Plastic sheet material can be produced from 0.3mm to 1.9mm, the normal width is 600mm, the width can exceed 1200mm, and the length is not limited.
Color: Black and white, can also be made another color, and the color order is 500KG.
Modified varieties: UHMW-PE Plastic can be added to the Glass Fiber, copper powder, and molybdenum disulfide enhancement plate according to customer's requirements.
Product certification: most environmental certification reports and safety reports forraw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
