Friction pad material is an important component of mine hoist friction throw into confusion, the coefficient of friction liner directly affect the safe operation and to enhance the efficiency of the machine was shipped, since the 1940s, due to the multi-rope friction hoist with a wound type Machine incomparable superiority friction pad material, has become one of the main shaft hoisting equipment Sichuan States. But because friction pad problems from time to time hoist rope friction "slip" phenomenon friction pad, serious yet major accidents occur plane crash and death of people, and to the production of huge losses. solve the "slip, one of the key issues is to increase the phenomenon of friction properties of the cushioning material closed now produced abroad gasket material on the whole, overall performance (especially friction coefficient) was significantly higher than China's production of materials, such as Poland, the busy movement of production pad friction coefficient can be higher than 20% of production to 30%, the gap is obvious, but the liner than the price of the foreign country several times higher, so the development of our own high-performance gasket material is important. As one of the main components of the friction pad multi-rope friction hoist, currently used in domestic friction hoist friction pad main poly Two liner vinyl chloride (PVC) and polyurethane pads (CPUR), the former low coefficient of friction (0.20), poor wear resistance, CPUR pad wear increased friction pad standard, but the friction coefficient still between 0.2 and 0.23, and due to poor processing performance, the car rope groove difficulties, technical factors also unstable product quality, the use of melt will appear, therefore, CPUR pad only in the friction coefficient of 0.22 Use the range performance characteristics: 1. friction coefficient under various conditions were greater than 0.25, fully meet the multi-rope friction hoist .2 require the use of high mechanical strength, non-material damage rope, easy on-site processing. Rope groove and its main mechanical properties are as follows: 3 for friction grease compatibility, friction grease on imports, domestic friction grease are applicable, with domestic LZM friction grease better .4 affordable (priced imports 50% K25. density of K25 87%), cost performance is better than imported high coefficient of friction pad pad, the user can bring considerable economic friction hoist rely on the friction between the rope and the pads to deliver power, So friction pad is an important part on the elevator, its performance will directly affect the safe use of lifting capacity and hoist. cushioning material mainly domestic early use of polyvinyl chloride (PVC), friction allowable coefficient value of 0.20, the wear resistance is poor, short life in the early eighties, with polyurethane (CPUR) rise product, its remarkable performance in terms of wear, so soon replace polyurethane PVC becomes Country of friction hoist pad main material, but is still low friction coefficient of polyurethane, is still among 0.2-0.23, and because of poor processing performance, the car rope groove difficult because the quality of technological factors of instability, use there will be melted and, therefore, CPUR pad can only be used within the scope of the friction coefficient of 0.22 is currently the coefficient of friction of the friction pad using Multi Rope Hoist 0.25 or more to be imported from abroad, but expensive and imports a longer period.
