Embodiment 1

[0029] Take some fresh sorghum stalks with leaves removed, slice the sorghum stalks obliquely through a chipper, and the thickness of the slices is 2.5mm; sieve the slices through a sieving machine to remove the skin, midridge and mud in the slices; the sieved Sorghum stalk slices are shaved by a roller flaker, and the area is 6mm 2 flaky shavings; put the flaky shavings into a tumble dryer at 180°C for 40 minutes to dry, the drum speed is 20r / min, and the moisture content of the dried flaky shavings is 4.8%; the dried flaky The shavings are separated by a cyclone separator and sent to the warehouse for storage; respectively take 45kg of dried flaky shavings, 4kg of urea-formaldehyde resin glue, and 1kg of waterproofing agent and put them into the mixer to stir evenly to obtain a mixture. The solid content in the urea-formaldehyde resin glue 14.5%; Pour the stirred mixture into a pressing mold with an inner diameter of 150cm, first pour 1 / 3 of the weight of the mixture into th...

Abstract

The invention discloses a method for processing a sorghum stalk shaving board. The method includes the steps of preparing a raw material, sieving, flaking, drying, storing, stirring the material, entering a mold, hot pressing, checking, being put in storage and the like. The shaving board processed through the processing method has an excellent mechanical property, the static bending intensity is larger than or equal to 16 MPa, the elasticity modulus is larger than or equal to 2117 MPa, the inner bonding strength is larger than or equal to 0.4 MPa, the thickness swelling rate of water absorption is smaller than 8%, and the method has the advantages of being low in cost, simple and convenient to implement in processing technology, capable of not generating pollutants and capable of not damaging the ecological environment; meanwhile, wood shaving is conduced first after the raw material is sliced, the quality evenness of wood shavings can be guaranteed, and therefore the surface flatness and fineness of the finished shaving board can be improved.

Description

technical field [0001] The invention relates to the technical field of artificial board production, in particular to a processing method of sorghum stalk particleboard. Background technique [0002] There are many types of wood-based panels, among which the performance of particleboard is comparable to that of medium-density fiberboard, and the cost is relatively low, so it has been developed rapidly in our country. Because the particleboard structure is relatively uniform and the processing performance is good, it can be processed into large-format boards according to needs. It is a good raw material for making furniture of different specifications and styles. The finished product particle board does not need to be dried again, it can be used directly, and the sound absorption and sound insulation performance is also very good. Traditional particleboard is mainly divided into the following three types: 1) log particleboard: such as pine or eucalyptus particleboard; 2) agri...
