Облицовка кромок клеями-расплавами
На протяжении многих десятилетий, в мебельной индустрии устоявшейся практикой было облицовывание торцов древесных панелей различными видами кромок. Требования к качеству, а именно к визуальной привлекательности, технический прогресс в области машиностроения, а так же почти безграничное разнообразие применяемых материалов – все эти факторы являются вызовом для клеевой технологии.
В современном производстве высококачественной мебели, качество облицовывания кромки все чаще становится ключевым критерием оценки качества всей мебели. Потребитель желает видеть едва заметный, идеальный клеевой шов .
Не в последнюю очередь из-за развития ультрасовременных методов производства, таких как лазер, плазма или технологий HOTAIR, в отрасли надолго заговорили о так называемом "нулевом клеевом шве". Эти технологии часто используют кромки с предварительным покрытием обратной стороны коэкструдированным полимерным материалом. Однако из за непрерывного и очень сложного процесса изготовления совместно экструдированных кромок, ограниченного термопластичными материалами, они , не могут найти столь широкого применения.

Directions for use
PUR hot melt adhesives can be processed on throughfeed lines at different feed speeds, as well as on roller and nozzle applicators. All parts of the melting and application units coming into contact with the adhesive should have a non-stick coating to prevent possible catalytic reactions due to metal contact. A non-stick coating will also facilitate a considerably easier cleaning.
The melting and application units should be equipped with a precise temperature control to prevent local overheating and unwanted secondary reactions. Heating the adhesive to a temperature above the recommended processing temperature will usually lead to a fast increase in viscosity of the melt due to a so-called thermal crosslinking reaction in the adhesive (the allophanate reaction), which is triggered by heat and does not need moisture.
Cleaning
If necessary, flush out hot melt remnants from the melt and applicator units with flushing agent Jowat® 930.94 (red). Crosslinked, solid material has to be dissolved with cleaner Jowat® 930.60 (please test for suitability before use).
