Why only pu castor to shoulder the important task so

Why only pu castor to shoulder the important task so? The loose wheel shaft and the nut tightening and check weld or support plate for damage. Overload or crash will lead to distortion. Stent deflects the overloaded pressure distortion on individual round wheels and cause premature failure. If it is lever type caster, should be to tighten the nut or solid rivet and ensure equipment mounting bracket without bending and pole installed correctly. Installing a caster wheel, lock nut or locking washers should be used. Expansion plug pole of castor installation to ensure that the plug rod firmly installed in a casing. Polyurethane foam plastics is used widely at present. Soft foam plastic is mainly used for furniture and transport all kinds of cushion materials, insulation materials, etc. ; Hard foam is mainly used in household appliances waterproof spray foam insulation layer, the house wall, pipe insulation materials, building plank, refrigerator and cold storage insulation material, etc. ; Half hard foam used in automobile dashboard, the steering wheel, etc. Market has polyurethane foam composite materials that are used for various specifications ( Two-component premix) Mainly used for ( Cold cure) High resilience foam, half hard foam plastic, casting and spraying hard foam plastic, etc. Polyurethane elastomer can be in a wide range of hardness has high elasticity and strength, excellent wear resistance, oil resistance, fatigue resistance and seismic resistance, with & other; Wear-resisting rubber & throughout; Said. Polyurethane elastomer in polyurethane products production are small, but the polyurethane elastomer has excellent comprehensive performance, has been widely used in metallurgy, petroleum, automobile, ore dressing, water conservancy, textile, printing, health care, sports, food processing, construction and other industrial sectors. Super-heavy castor material selection, can according to different environment can choose different material ( Nylon, polyurethane, cast iron, rubber) The caster. Each material has advantages and disadvantages, nylon material castor compressive load is big, wear resistance, noise, shock absorption effect is not good. Cast iron bearing large castor, pavement, is suitable for the track or road environment of the request is not high, compressive, wear-resisting rubber heavy duty casters than nylon, good shock absorption, bearing large environment need wheels widening thickening, between nylon and rubber, polyurethane material caster can bearing capacity, low noise, under the use environment is not very dirty it is recommended to use.
