Children's furniture plate MDF production process
1. Shavings
It is a manufacturing facility for raw materials for the entire board production. It mainly cuts loose wood into chips that meet the production specifications to provide better conditions for fiber separation.
2, hot grinding
The chips cut from the chipping workshop were preheated and mechanically separated to give fibers.
3, fiber drying
The heat-grinding fiber plus sizing makes the moisture content of the fiber reach 40%-50%. If it is difficult to adapt to the following sections without drying the fiber, the main control drying temperature in this process section is about 165°C, which will not cause resin pre-cure. This affects the mechanical properties of the plate's MOR and IB.
4, pavement
It will be dried and stored in the fiber silo for a certain period of time. After being fed to the paving machine by a feed fan, the fiber will be roughly formed by vacuum air flow, and then the forming process of the plate will be realized by a stripping roller and a prepressing machine.
5, hot pressing
It is an important process for the manufacture of MDF. It plays a decisive role in product quality and production. It is the combination of heat and pressure, moisture vaporization in the slab, evaporation, density increase, adhesive, waterproof agent. Redistribution results in a series of changes in each component of the raw material, so that various binding forces are formed between the fibers and the product reaches and meets the quality requirements.
6, sewage treatment
The dry production of MDF basically does not have a large amount of industrial wastewater. It is mainly corked water that is squeezed out by the feed spiral. For this kind of wastewater, we mainly use anaerobic treatment, and the process flow chart is as follows: Wastewater from workshop -> Precipitation -> Water collection tank -> Anaerobic tank -> Air floatation tank -> SBR tank -> Clear water tank -> Fiber Transitioner -> Drainage.
