Abstract
A kind of utilize wet production please both parties in the production method of density thick fiber plate, it is at first to adjust hot press oil pressure pressure, producing thickness is 9-12mm medium density fibre board (MDF), then that two this fiberboard reticulate pattern faces are relative, uses cold press cold moudling behind the spraying resin glue.Utilize the present invention produce in density thick fiber plate, it is big to have overcome the dry technology for production equipment investment, and the fiberboard thickness that wet process technique is produced is thin, one side has reticulate pattern, yielding shortcoming.
Description
The invention belongs to a kind of production method of medium density fibre board (MDF), particularly a kind of utilize wet production please both parties in the production method of density thick fiber plate.
At present, the technology of producing medium density fibre board (MDF) has two kinds of dry method and wet methods, and dry technology for production is that dried fiber mixes glue, airflow pavement pressure forming then.Dry production medium density fiber plate thickness adjustable range is big, and the fiberboard two sides that is produced is smooth, but equipment investment is big especially.Wet process technique is the production line that utilizes the wet production high density fiberboard, and the charging crane spacing is strengthened, and reduces the number of plies (15 layers to 12 layers) and adjusts pressure, and is hot-forming.But the medium density fibre board (MDF) of this explained hereafter one side light simultaneously has reticulate pattern, and thickness is no more than 12MM, plate surface density difference, and the moisture absorption ratio difference, yielding.
Purpose of the present invention just provides a kind of advantage of taking into account dry method and wet processing, and the production method of small investment, equipment, the simple a kind of medium density fibre board (MDF) of technology.
Task of the present invention is finished like this: utilize the equipment of existing wet production medium density fibre board (MDF), at first hot press oil pressure pressure is transferred to 30-60Kgf/CM
2, 42-45Kgf/CM preferably
2, the medium density fibre board (MDF) of production thickness 9-12MM, the reticulate pattern face with two this medium density fibre board (MDF)s is relative then, uses cold press cold moudling behind the spraying resin glue, and the medium density fibre board (MDF) after the moulding is cut edge in length and breadth gets final product at last.
The medium density fibre board (MDF) that utilizes this method to produce, it is thin to have overcome the fiberboard thickness that the dry technology for production equipment investment is big, wet process technique is produced, and one side has reticulate pattern, yielding shortcoming.
Embodiment:
Utilize cotton bavin to produce thickness and be the 28MM cotton stalk medium density fiberboard: at first cotton bavin is sent-separates-magnetic separation-screening-applying wax (54 degree, applied amount 1.5-1.8%) through cut-out-dedusting-wind, at 140 ℃-160 ℃ of temperature, air pressure 4-6Kgf/CM
2Under the condition boiling 5-15 minute defibrator process drainage-dilution (concentration numbers 3.5%) finish grind 8 times of drainage (freeness 30-40)-Shi GF-3 phenol glue 30% dilutions again, 9 times of DN-1 Lauxite 15% dilutions, adjusting pH value is 3.8, concentration 2.0%-moulding, dewatering pressure 63Kgf/CM
2, slab is moisture 56%, thickness 7CM.Hot press oil pressure pressure is transferred to 43Kgf/CM
2Vapour pressure 6,5Kgf/CM
2, 200 ℃ of temperature, hot pressing 45 minutes, the-gluing-plywood-warehouse-in of cutting edge in length and breadth, the medium density fibre board (MDF) two sides that utilizes said method to produce is smooth, thickness 28MM, density 0.7g/CM
2, water absorption rate 33%, moisture content 6%.
Claims (2)
1, a kind of production method of medium density fibre board (MDF), when it is characterized in that slab hot pressing, hot press oil pressure pressure is 30-60Kgf/CM
2, produce thickness 9-12MM medium density fibre board (MDF), the reticulate pattern face with two this medium density fibre board (MDF)s is relative then, uses cold press cold moudling behind the spraying resin glue.
2, a kind of production method of medium density fibre board (MDF), when it is characterized in that slab hot pressing, hot press oil pressure pressure is 42-45Kgf/CM
