Textile Processing and Finishing must out of necessity adapt to new technologies, and RHL have made it a priority to re-design their roll covers to suit the latest conditions. The biggest change in the processing industry of recent years has been the steady increase in harsh or aggressive chemicals and resins that have come into common use.
The necessity for a new type of squeezing roll cover has led RHL to develop a revolutionary new range of high efficiency squeezing covers that will fully resist an array of chemicals and resins, even at high temperatures, while at the same time giving optimum squeezing performance and increased roller life, leading to enhanced productivity. The new MaxResistor compounds have been extensively developed to perfection in Europe and the USA.
The new range of covers has been specifically designed to suit OEM machinery builders as well as the end-user Processing mills. RHL can utilise its comprehensive design and manufacturing facilities to make new rolls of the highest quality. Roll covers are custom made with full compound mixing from uniquely developed blends, backed up by technical support from our fully equipped laboratory, complete with R&D capability.
The new MaxResistor roll covers are specifically designed to be used in the harsher environments of Dyeing and Bleaching ranges – typically bleaching processes in oxidising medium (H2O2) at high temperatures, and Mercerizing ranges with hot caustic solutions (NaOH). Chemical resistance is the primary concern, along with good liquid expression, good abrasion resistance and excellent bond strength leading to optimum lifetime of the roll cover.
The ability for MaxResistor to withstand aggressive liquids such as caustic soda (NaOH) or hydrogen peroxide (H2O2) solutions, at high temperatures has been particularly targeted in its development. In these situations, the rate of chemical action, or chemical attack, is speeded up by the increased temperature. In some cases, the rate of reaction doubles for every 10˚C increase in temperature. This is in addition to any heat degradation effect which the cover may experience purely as a result of high temperature.
MaxResistor utilises a special blend of polymers and resins that have been uniquely formulated to match the specific running environment. The MaxResistor cover can be supplied in three different variations (A, B and C), depending on the type of chemicals in use.
