Description
Technical field
The utility model belongs to high-speed railway, railway, highway communication and man-made noise and administers field, particularly relates to a kind of mould of sound-absorbing composite board.
Background technology
Acoustic board generally adopts wooden, several material such as mineral wool, cloth art and polyester fiber to make.
1. wooden
Wooden sound-absorbing plate processes according to Principles of Acoustics exquisiteness, is made up of facing, core and sound-absorbing mat.Wooden sound-absorbing plate divides groove wood abatvoix and hole wood abatvoix two kinds.
2. mineral wool
Mineral wool abatvoix surface treated versions enriches, and sheet material has stronger decorative effect.The treated annular knurl type mineral wool board in surface, is commonly called as " caterpillar ", and surface is covered with the different hole in the depth, shape, aperture.
3. cloth art
Cloth art abatvoix-core material is centrifugally glass-wool.Centrifugally glass-wool, as a kind of acoustical material in long-term extensive use all over the world, is proved to be and has excellent sound absorbing capabilities.
4. polyester fibre acoustic panel
Polyester fibre acoustic panel is a kind of desirable sound-proof decorative materials.The polyester fiber of its raw material 100%, have sound-absorbing, environmental protection, fire-retardant, heat insulation, insulation, moistureproof, anti-mildew, easy dedusting, easily cutting, can parquets, easy construction, good stability, impact resistance is good, independence is good, cost performance advantages of higher, have that to enrich multiple color available, the attraction decoration demand of different-style and level can be met.
The opening of railway, highway brings fast and simultaneously easily, also cause the environmental pollution of strong noise to subjective reflection, noise pollution has become large public hazards of China's urban and rural environment, the normal life of serious threat people and physical and mental health.Noise not only can cause damage to hearing, multiple carcinogenic fatal disease can also be brought out, also the life and work of people is disturbed to some extent, the pernicious stimulation of noise, have a strong impact on our sleep quality, and can cause tired, cause dizziness, headache, insomnia, dreaminess, failure of memory, the neurasthenia symptom such as absent minded and feel sick, for telling, having a stomachache, the symptom of digestive tract such as abdominal distension, appetite is dull.Noise affects the nervous system of people equally, makes people's irritability, irritability.
Original acoustic board processing technology is: adopt perforate+filling sound-absorbing material form after tube drawing+health of loosing core, namely first square shaped core pipe is placed in acoustic board production line, cast concrete, during Deng concrete setting to a certain degree, extracted by core pipe, acoustic board health subsequently, after preserving period, acoustic board is placed on perforate on tapping machine, dries rear filling sound-absorbing material.
The shortcoming of this production technology is: 1. the production cycle is long, operation is complicated: acoustic board out needs afterwards to hang other local health in production line, the perforate of perforate production line is hung again after health is good, and then hang away, dry rear filling sound-absorbing material, finally pack, repeatedly have bad luck and cause personnel cost to increase, occupied ground is many, and place utilization rate is low, and in the process of having bad luck, increase the probability that acoustic board damages, damages; 2. contaminated environment: acoustic board cutting machine in Tapping procedures needs to use water, and the concrete powder of cutting flows away along with water, causes water pollutions, and increases water rate cost, cleaning sediment also can increase personnel cost; 3. the wasting of resources: the materials such as the cement of acoustic board perforate outflow with water, not recyclablely reuses; 4. damage of product rate is high: in tube drawing process, if tube drawing too early or excessively late, all can cause acoustic board to crack.If acoustic board is placed uneven or tapping machine translational speed is too fast in Tapping procedures, misoperation, also can make acoustic board crack.
This production technology falls behind, and the production cycle is long, and cost is high, causes the wasting of resources, contaminated environment.
