The H-type safety wire is composed of rails, sheaths, current collectors, hangers, connectors, clips, and end caps. If necessary, some other accessories can be configured. Here are some of the major ones.
(1) Guide rail and sheath guide rail: It is made of aluminum alloy material and is embedded with "V" shaped stainless steel tank to ensure the wear resistance and stability of the collector brush and good contact with the guide rail.
Sheath: The material is engineering plastics, with wear resistance, anti-aging and flame retardant, can be well insulated guide rail.
(2) The current collector adopts a support structure. Its role is to supply power to mobile devices. It is mainly composed of special carbon brushes, terminal posts, plastic shields, and support arms. If the equipment is to be overhauled, the collector should be powered off to ensure safety.
(3) The connector is mainly used to connect the ends of the rails, and the interior includes the pressure plate, bolts, etc. The outer shell is made of engineering plastics, and the ports are left on the outer shell, and lead wires can be introduced.
(4) Hangers, holders, and end cap hangers: They are mainly used for hoisting trolley rails. The material is engineering plastics.
Fixer: It is mainly used to fix the guide rail guide rail. When the guide rail is telescopic, it can guide the guide rail to extend to both sides of the fixture.
End cover: generally at both ends of the rail, play a role in insulation protection.
Finally, Xiao Bian introduced the maintenance of the H-type safety wire.
The maintenance of the H-type safety wire is:
(1) The current collector should avoid collision, stepping, etc. In the same phase, if a dual current collector is used, attention should be paid to the situation where no phase short circuit occurs.
(2) The wear condition of the carbon brush of the collector should be checked regularly. If it is seriously worn, it should be replaced in a timely manner. When replacing, be careful to disconnect the power first to prevent danger.
(3) The springs in the current collector should be checked for fatigue, insufficient elasticity, and replaced if necessary.
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.
The thickness of plate can be produced from 2mm to 180mm, the usual specification of 2-10mm is 600mm* 1200mm, and the commonly used specification of 10-180mm is 1200*3080mm. UHMW-PE Plastic can also be customized according to requirements, and the width cannot 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.
Add antistatic agent to the permanent plate, the volume resistance value of 10 to the 6 to 9 power.
Add flame retardant to the flame retardant board from UL 94v-0 to HB combustion grade, and other modification requirements are required to customize various additional properties according to the actual use of the customer.
Product certification: most environmental certification reports and safety reports forraw materials, such as SGS report, CTI report, UL report, MSDS safety information, etc.
