The hotmelt application system of any machine is the heart of the wrapping or edgebanding process It requires particular maintenance and care, because the cleaning condition is decisive for the quality of the products. The continuous production starts and stops can cause the hotmelt glue to cure inside the system. Over time the glue pump, filters and the heated hose are slowly but surely clogging up. Initially you might not notice that less glue is flowing. In the worst-case foiling results will decrease and delamination can occur due to a lack of glue. At the same time, cured glue particles can find their way through the filters and end up as spots under the foil causing defects and claims from customers.
To avoid all this, it is essential to keep the glue system clean and in the best possible conditions right from the beginning. Before you stop the production for a longer time, for example before long weekends or holidays, flush out all the glue and purge the system with the Cleaner Blu.
CLEANER BLU blocks the chemical reaction of the hotmelt PUR glue and prevents it from clogging up the glue system. It is of essential importance to start the regular cleaning and maintenance while the system is still clean. If you try to clean an already contaminated glue system, you might only loosen part of the cured glue. This will cause an increased amount of particles that will take long to get rid off.
CLEANER BLU is also used for sealing the glue head before both night and weekend stops. By applying a layer on the slot, it prevents the adhesive from cross-linking in contact with air. It will be sufficient at the restart to flush out the cleaner and some adhesive to resume the lamination process.
CLEANER BLU is the ideal product for preventive cleaning and maintenance that will save you a lot of trouble and costs for replacement of machine parts. Not only will the glue melter, the glue hose and the filters last longer but you will also notice an even and impeccable glue pattern on the foil.
