Description
Technical field
The invention belongs to beaver board manufacturing technology fields, and in particular to a kind of manufacturing method of abatvoix substrate.
Background technique
Abatvoix is divided into 3 classes by material: 1. wooden, Wooden sound-absorbing plate is process according to Principles of Acoustics exquisiteness, by adoring
Face, core material and sound-absorbing mat composition.Wooden sound-absorbing plate is divided to two kinds of slot wood abatvoix and hole wood abatvoix.Medium density fibre board (MDF) just
The structure sound-absorbing material of circular hole is opened at the slot of face open form formula Three-dimensional triangle or cylinder, the back side, and facing spray painting (can be selected by customer requirement
Select color).2. mineral wool, mineral wool abatvoix surface treated versions are abundant, and plate has stronger decorative effect.Surface is treated
Annular knurl type mineral wool board, is commonly called as " caterpillar ", and surface is covered with the different hole in the depth, shape, aperture.3. fabrics, fabrics is inhaled
Its core material of soundboard is centrifugally glass-wool.Centrifugally glass-wool is as a kind of in long-term widely applied acoustics material all over the world
Material, is proved to the sound absorbing performance for having excellent.
The present invention can prepare 840~850kg/m of 15mm density3Abatvoix substrate, fibre morphology is fine and smooth, subsequent to engrave
Milling, fluting, punching.
Summary of the invention
In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a kind of processing of application wood material to make
Make the manufacturing method of high density abatvoix substrate.
The invention is realized by the following technical scheme.
A kind of manufacturing method of abatvoix substrate, comprising: the preparation of fiber → sizing and drying → is mated formation and precompressed → plate
After material hot pressing → semi-finished product post-processing through inspection, sawing, be packaged to obtain the final product, in which:
In the preparation section of the fiber, 8~9bar, 3.0~4.0min of boiling are pressed in the boiling of Defibrating Technology, grind chamber pressure
8.5~9.5bar, 50~60kg/m of fiber bulk density3, fine and smooth fiber is made；
In the sizing and drying process, apply 220~225kg/m3Adhesive.
In the more excellent disclosed example of the present invention, in the preparation section of the fiber, 8.5bar, boiling are pressed in the boiling of Defibrating Technology
3.5min grinds chamber pressure 9.0bar, fiber bulk density 55kg/m3。
In the more excellent disclosed example of the present invention, in the sizing and drying process, the adhesive is 1.05 or less E1 of molar ratio
The cyanurotriamide modified urea resin adhesive of grade, self-control.
In the more excellent disclosed example of the present invention, in the plate hot pressing process, continuous flat press first, second, third and fourth, 5th area
Hot pressing temperature be respectively 225~240 DEG C, 225~240 DEG C, 220~235 DEG C, 190~205 DEG C, 180~195 DEG C, setting pair
The hot pressing pressure for answering the first to five area is 135~235N/cm2, 40~185N/cm2, 11~18N/cm2, 90~200N/cm2、20
~60N/cm2, hot pressing is carried out for 10.8~12.2s/mm in thermal ventilation to the slab after precompressed.
Plate is made in the method according to the present invention, and density is 840~850kg/m3。
Beneficial effect
Abatvoix substrate obtained by the present invention have sound-absorbing, environmental protection, it is fire-retardant, heat-insulated, heat preservation, it is moisture-proof, anti-mildew, easily remove
Dirt, easily cutting, can parquets, the advantages that easy construction, stability is good, impact resistance is good, independence is good, cost performance is high, can expire
The sound-absorbing of sufficient different-style and level decorates demand.For music hall, cinema, recording studio, studio hall, monitor room, meeting room,
Gymnasium, exhibition center, dancing hall, karaoke chamber, family's video display Room factory, quiet room, court, Conference Hall, the acoustic fields such as hearing room
Sound-absorbing textile mills and the overproof workshop of noise and large public building acoustic wall board, ceiling suspension hook top plate.
