Description
Technical Field
The invention belongs to a novel polymer composite material, and particularly relates to a corrosion-resistant wear-resistant roller wrapper.
Background
The modern novel loom take-up mechanism has the characteristics of continuity, large package, electronic control, automatic doffing and the like. The coiling mechanism is the same as the let-off mechanism, and whether the integral coiling action is accurate, stable and uniform has close relation to the quality of the fabric.
The winding mechanism is used for leading the woven fabric away from the cloth fell and winding the woven fabric onto a cloth roller. At the same time, the take-off speed determines the geometric density of the weft yarns in the fabric. The speed is high, the weft density is small, otherwise, the weft density is large. If the cloth rolling mechanism runs badly, the improper matching with the let-off and tension adjusting mechanism will result in uneven weft density and other weaving defects. This requires the take-up mechanism to satisfy two basic conditions: the coiling effect is accurate and stable; the cloth rolling capacity is large, and the cloth rolling tension is uniform. Both functions are mainly provided by the traction layer of the roll cover around which the roll shaft is wrapped. The traction layer must therefore have a stable and suitable coefficient of friction and excellent wear resistance.
When the novel weaving machine works, the roller cover is directly or indirectly contacted with air compressor oil, spinning machine oil and lubricating oil, and the traction layer is easily corroded and swelled by the media to be damaged. Therefore, the surface traction layer has the advantages of excellent spinning machine oil corrosion resistance, good lubricating oil swelling resistance, wear resistance, aging resistance, water resistance, proper elasticity and the like, is in contact with the fabric in use, has different patterns according to different fabric types, and meets the requirements of fabric friction traction.
The design principle of the traction layer high molecular material formula is that the traction layer high molecular material formula has good tolerance performance to the contacted solvent and oil agent and has excellent wear resistance. The roller cover in the current market adopts common nitrile rubber as a main material, but the corrosion, swelling and damage phenomena often occur when the novel weaving machine is applied, and the service life of the roller cover is shortened. The corrosion-resistant and wear-resistant polymer composite material is preferably researched, and the general roll cover product adopts nitrile rubber as a main material, because the nitrile rubber has good oil resistance due to the large polarity, but the material has resistance to nonpolar oil, and the resistance to complex components in spinning machine oil is insufficient to meet the application requirement.
