Definitions
- the present invention relates to a humidifying agent for pressing material with cake offset material cake, in particular for the production of material plates, preferably wood-based panels and a method for pressing material cake.
- Such moistening has the disadvantage that a metering of the moistening agent due to the application of the moistening agent in the vaporous state is only possible in a very inaccurate manner.
- a humectant which avoids disadvantages of the prior art.
- the object is achieved by a humectant containing polyols, acylglycerides or their derivatives, surfactants and water.
- the polyols have at least two OH groups, it being possible for the OH groups to be primary, secondary or tertiary OH groups.
- the polyols have preferably at least two primary OH groups. Such compounds are also referred to as glycols.
- polyols and higher-chain polyols are used.
- the wetting agent contains acylglycerides containing unsaturated fatty acids. Such can be obtained for example from rapeseed oil.
- acylglycerides monoacylglycerides, diacylglycerides or triacylglycerides can be used. If triacylglycerides are used, they are preferably substances which are liquid at room temperature (25 ° C.). The use of vegetable oil based substances is preferred.
- the triacylglycerides may be simple triacylglycerides in which the side chains are the same, but mixed side chains may also be present. Derivatives include in particular sulfated and phosphated derivatives.
- only one or two hydroxyl groups may be esterified and the other two may be free or modified.
- humectant according to the invention are preferably 5 to 20 parts by weight of polyol together with 2 to 10 parts by weight of acylglycerides or Acylglyceridderivaten and 10 to 30 parts by weight of surfactants.
- the amount of water can be adjusted depending on the machine needs. Typically, based on the above information, the product contains relatively much water.
- the moistening agent can be stored as a concentrate, then the amount of water based on the above information is about 60 parts of water. However, the product can then be diluted by a factor of 2 to 10 before application to the material cake.
- ionic surfactants eg.
- anionic and cationic surfactants have proven suitable. But in some embodiments, too non-ionic surfactants are used.
- a mixture of surfactants is used.
- the moistening agent according to the invention may contain further auxiliaries, for example dyes or fragrances. Furthermore, thickeners can be used to regulate the viscosity. It is also possible for fillers or adhesion promoters to be present which have a smoothing effect on the surface of the pressed material plates.
- the moistening agent according to the invention can in principle be sprayed onto a material cake. Preferably, however, the moistening agent is applied with a roller. With the help of an applicator roll and the adjustable against the applicator roller metering roller accurate metering of the amount of moistening agent transferred to the material cake is possible. As a result, the moisture necessary for rapid compression and a good surface finish can be transferred to the material cake. By applying the moistening agent to the material cake, the moistening agent initially remains on the surface of the material cake or in the area near the surface of the material cake.
- the steam burst produced during the pressing of the material cake which is intended to penetrate into the interior of the material cake, can be produced in a particularly advantageous manner, since the burst of steam penetrates into the material cake from above and below.
- the moistening of the material cake from below deformation effects of the material cake resulting from the moistening.
