The effect of press mass temperature differences on flatness in MDFLAM production

MDFLAM is a group of materials obtained by combining decorative paper impregnated with melamine resin into MDF sheets under temperature and pressure. MDFLAM production is carried out by covering both sides and one side of the board depending on customer demand and usage feature. One of the common problems in MDFLAMs, which are coated on one side and raw on the other, is that the plate tends to flatness. This causes problems in the final processing of MDFLAMs. The aim of the study is to determine the effect of press mass temperature difference on flatness of single face coated MDFs. To meet this objective; medium density fiberboard panels were produced in ？amsan Ordu A？. MDF plants. Different temperature parameters have been used in order to determine the effect of press mass temperature difference on board flatness. Prior to flatness test, sample panels were conditioned at 20±2°C, and 65±5 % of relative moisture content to reach the moisture content of 12 %. As a result of the study, it was observed that the best results were determined in the groups where the temperature difference of the melamine coating press was 25°C
