This drill bit applies the new pre-alloyed powder to the diamond bit matrix. The cold press-hot press process is used to produce a single-layer nozzle high-carb diamond bit with a significantly improved bit body strength and a working layer of more than 20 mm. After the successful development of the new high-tire diamond bit, it was tested in the Yunnan Dulong drilling project. The results show that in the VII-VIII (7-8) grade sandstone, the drilling efficiency of the product exceeds 3 m / h and the service life exceeds 400 meters, 1.3 times and 2 times respectively for conventional diamond drill bits; in VIII-IX (8-9) grade granite, the drilling efficiency exceeds 1.5 m / h and the service life exceeds 150 m, which is 1.2 times that of conventional diamond drill bits. And 2 times.
In deep drilling engineering, bit quality is a key factor affecting drilling schedule and cost. According to Zhou Tiansheng, chief engineer of Guilin Diamond Industry Co., Ltd., the test shows that the new high-tire diamond drill can completely replace the imported products, and the cost performance is higher than that of the imported drill bit. It is a tool for comprehensively implementing deep engineering and exploring large-scale resources in a large scale. . At present, the drill has been used in deep drilling projects by several drilling companies in Yunnan and Sichuan provinces.
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
