| description | The invention discloses a manufacturing method of a 25mm medium density fiberboard. The manufacturing method of the 25mm medium density fiberboard comprises the following steps of firstly, conducting mixing, wherein raw materials are mixed and dried, so that a wood fiber mixture with the moisture content being 7%-9% is obtained, the raw materials comprise, by weight, 90-95 parts of wood fiber and 4-6 parts of urea resin, and the wood fiber comprises 26%-36% of barks; secondly, conducting pre-pressing, the wood fiber mixture is pre-pressed for forming under the condition of 1-2 MPa; and thirdly, conducting hot-pressing, wherein hot-pressing is divided into nine levels to be performed. The medium density fiberboard manufactured through the manufacturing method of the 25mm medium density fiberboard has a good static bending intensity and a good elasticity modulus.
本发明公开了种25mm中密度纤维板的制备方法，包括以下步骤：步骤1：混合，将原料混合干燥得到含水率7-9％的木质纤维混合物；其中，所述的原料包括90-95重量份的木质纤维、4-6重量份的脲醛树脂，所述的木质纤维中含有26-36％的树皮；步骤2：预压，将木质纤维混合物在1-2MPa条件下预压成型；步骤 |
