Edgebanders Cleaning and adhesive change
●A fully functional adhesive application system and melter are of maior importance for a smooth and reproducible adhesive application. The cleaning effort varies depending on the application system and unit, and depends largely on the type of adhesive used. lf the old and the new hot melt adhesive have different chemical bases, it is necessary to clean the equipment more thoroughly. Before the cleaning of the application system is started, it must be tested whether the adhesives are compatible with each other as well as with the Jowats flushing agents and cleaners. Especially in closed application systems it should be ensured that the PUR hot melt adhesive and the Jowat° flushing agent are melted evenly, to prevent plugged hoses and nozzles due to an unwanted reaction. lf the processed adhesive was a PUR hot melt, it is especially important that the system be cleaned before extended down-times (e.g.on weekends, holidays, periodic shutdowns, etc.). Jowat supplies a range of flushing agents and cleaners for that purpose.
●Modern PUR hot melt adhesives for edaebanding are characterised by a moderate reactivity and thus a relatively slow chemical crosslinking process. In many cases, the PUR hot melt adhesive can therefore remain in the heated tank overnight without the system having to be cleaned. However, this is not a universal characteristic and depends on the individual PUR hot melt product. Please contact a specialist from Jowat to check whether the adhesive used in your application generally also provides this processing advantage.
