Description
Technical Field
The invention belongs to the technical field of glass production processes, and particularly relates to a sound insulation glass processing process.
Background
With the continuous development of society, the problem of noise pollution is more and more serious. Like other industrial pollutions, noise pollution is a nuisance which harms human environment, and not only affects hearing, but also has adverse effects on the cardiovascular system, nervous system and endocrine system of human. Therefore, sound insulation measures need to be taken in time.
In order to solve the above problems, soundproof glass has appeared on the market. The sound insulation glass is a glass product which plays a certain role in shielding sound, and is usually a laminated glass with a double-layer or multi-layer composite structure, sound insulation damping glue (film) in the middle of the laminated glass plays a key role in weakening and attenuating sound transmission, and the glass product with the sound insulation function comprises the laminated glass. Although the conventional soundproof glass has a certain soundproof effect, the soundproof glass is insufficient in strength, hardness and the like, and is easily broken by impact. After the sound-insulating glass is used for a long time, sealing glue between the glass is easy to crack and bubble under the action of outside water, gas and the like, so that outside air enters an interlayer of the sound-insulating glass, and the sound-insulating effect is influenced.

(8) vacuumizing: placing cleaned glass on a platform, smearing chemical liquid medicine on the surface of the glass, placing two pieces of smeared glass on the platform for laminating, simultaneously performing the operations of exhausting, vacuumizing, edge sealing and sealing in the laminating process, and keeping the vacuum degree in the glass at 0.01-0.05MPa after laminating is completed;
(9) high-pressure sizing: putting the glass obtained in the step (8) into a high-pressure kettle, and pressurizing when the temperature in the kettle rises to 65-80 ℃ to ensure that the air pressure in the kettle reaches 0.8-1.0 MPA; continuously heating the kettle to the temperature of 120-; cooling to 40-50 deg.C, exhausting gas, and reducing pressure to atmospheric level.
The working principle of the basic scheme is as follows: grinding the raw materials to 400-600 μm, mixing and drying, wherein the steps are adopted for improving the uniformity of the mixed raw materials and facilitating melting. The clarifying agent is added in the manufacturing process to reduce the generation of bubbles in the glass liquid, and the decoloring agent is also added in the production process, and the main function of the decoloring agent is to eliminate the undesirable color brought to the glass by impurities in the raw materials, so that the glass is colorless and transparent.
After cutting, the surface of the glass is stained with impurities such as dust, oil stain and the like, the glass is placed on the supporting plate, and the glass is fixed by the positioning unit. The motor is started to drive the rotating cylinder to rotate towards the fixed direction, the push block moves downwards under the driving of the rotating cylinder, the push column moves downwards together, the pressure in the fixed cylinder is reduced at the moment, the one-way valve is opened, and outside water can enter the fixed cylinder through the water inlet pipe.

The cleaning rod continuously rotates along with the movement of the rotating cylinder, the brush hair on the cleaning rod cleans the surface of the glass, and the brush hair can clean away dirt attached to the surface of the glass under the combined action of water. When the motor rotates towards the fixed direction, the motor drives the inner ring of the one-way bearing to rotate through the rotating shaft, but the outer ring of the one-way bearing does not rotate at the moment, so that the supporting plate does not rotate. After dirt on the surface of the glass is cleaned, the motor is enabled to rotate in the opposite direction, the push block drives the push column to move upwards under the driving of the motor, the push column extrudes water in the fixed cylinder, at the moment, the first one-way valve is opened, and the water in the fixed cylinder is supplemented into the rotating cylinder. The motor rotates in the opposite direction, the motor drives the supporting plate to rotate through the rotating shaft and the one-way bearing, and water drops on the glass are thrown out under the action of centrifugal force. When the glass on the supporting plate is far away from the cleaning unit after the water on the glass is dried, the motor is turned off, and the next glass to be cleaned can be installed while the cleaned glass is taken down.
And (8) coating a chemical liquid medicine on the surface of the glass, wherein the chemical liquid medicine can improve the performance of the sound-proof glass, improve the strength and hardness of the sound-proof glass and avoid the sound-proof glass from being easily broken after being impacted. After vacuumizing and edge sealing, the soundproof glass is placed in the high-pressure kettle, external force is applied to the soundproof glass, so that the two pieces of glass are more tightly attached to the sealing glue, and the phenomenon that the sealing glue cracks and foams to cause air to enter the interlayer and reduce the soundproof performance of the soundproof glass under the action of external water and gas in the future is avoided. The temperature and the pressure in the high-pressure kettle are gradually adjusted, but not increased at a time, so that the sound-proof glass has an adaptive stage, and the sound-proof glass is prevented from being damaged due to the fact that the sound-proof glass cannot bear high temperature and high pressure.
The beneficial effect of this basic scheme lies in:
1. the production process is utilized to produce the sound insulation glass, and the strength and the hardness of the sound insulation glass can be enhanced while the sealing property of the sound insulation glass is ensured.
2. When using glass belt cleaning device to wash glass, wash the pole and constantly rotate, the impurity on the glass can be detached to the brush hair, and meanwhile, the water in the rotary drum sprays glass's surface through the second check valve, for glass provides clean water, does not need additionally to set up water jet equipment, makes glass's washing cleaner.
3. When a motor on the glass cleaning device rotates reversely, water in the rotating cylinder can be supplemented regularly, and workers do not need to supplement water regularly, so that the efficiency is effectively improved. Meanwhile, when the motor rotates reversely, the motor drives the supporting plate to rotate, and water drops on the glass are thrown out under the action of centrifugal force, so that the glass becomes dry; meanwhile, as the cleaning rod continuously rotates, the bristles become dry, and when the glass moves to be in contact with the bristles, the bristles can further wipe water stains on the glass.
4. The glass cleaning device can be used for spraying water, cleaning, drying and other operations on glass, so that the device structure is simplified, and meanwhile, the glass cleaning process is simplified.
