A kind of equipment for producing high-temperature resistant nano aerogel felt
Aerogel felt is a new type of flexible thermal insulation material, which combines nano aerogel with inorganic dimension. Its main performance characteristics are as follows:
1、 Low thermal conductivity
The thermal conductivity of aerogel felt is extremely low, usually between 0.02 and 0.1 W/(m · k), which makes it have excellent thermal insulation performance. Its insulation effect is 2 to 5 times that of traditional insulation materials, effectively reducing heat loss and improving heat source utilization efficiency.
2、 High temperature resistance
Aerial gel felt has high temperature resistance, and its applicable temperature range is generally between -200 ℃ and 1000 ℃ (related to specific products). Some products can withstand high temperatures up to 1100 ℃. In high temperature environment, the performance advantage of aerogel felt is more obvious.
3、 Soft and easy to cut
The aerogel felt is soft, easy to cut and sew, and can meet the insulation requirements of pipes and equipment in different shapes. This greatly reduces the time and labor costs required for installation.
4、 Inorganic fire prevention
The aerogel felt has inorganic fire resistance, and the fire resistance rating usually reaches B1 to A. Its unique three-dimensional network structure avoids the significant decrease in insulation effect caused by sintering deformation, settlement, and other insulation materials during long-term high-temperature use.
5、 Overall hydrophobicity
The aerogel felt has an overall hydrophobic property, which can effectively prevent moisture from entering the pipeline and equipment interior, thus extending the service life of equipment and pipelines.
6、 Green and environmentally friendly
Aerogel felt is a kind of green environmental protection material, which will not pollute the environment during its production and use. At the same time, it can also replace traditional flexible insulation materials such as glass fiber products, asbestos insulation felt, silicate fiber products, which are not environmentally friendly and have poor insulation performance.
7、 Lightweight and high-strength
Aerogel felt is light and has high tensile and compressive strength, which makes it more convenient during transportation and installation, and can ensure the thermal insulation effect.
To sum up, aerogel felt has excellent properties such as low thermal conductivity, high temperature resistance, softness and easy cutting, inorganic fire prevention, overall drainage, green environmental protection, light weight and high strength, and is widely used in industrial pipelines, storage tanks, industrial furnaces, power plants, rescue pods, warship bulkheads, bullet trains, directly buried pipelines, injection molding machines, removable insulation sleeves, heavy oil recovery high-temperature steam pipelines, transportation, household appliances and other fields.
The invention relates to a silicon dioxide nano aerogel gel adhesive equipment, which is used in the silicon dioxide nano material composite molding production line,
The equipment structure is as follows:
The unwinding section adopts a 6-station independent structure. Divided into two levels, A and B, A has three workstations. A1, A2, A3 are used for nano aerogel materials. B has 3 workstations, B1, B2, and B3 are used for fiber composite materials. During the operation, A1 and B1 are simultaneously unwinding. When the roll diameter of A1 and B1 materials decreases from large to small until the end, A2 and B2 start working. When the roll diameter of A2 and B2 materials decreases from large to small until the end, A3 and B3 start working. When the roll diameter of A3 and B3 materials decreases from large to small until the end, A1 and B1 start working in a cyclic manner. The first-time use of disposable installation of 6 rolls of materials has saved the frequency of material replacement downtime, improved work efficiency, and reduced material waste.
The 2 unwinding composite parts are heated by pressure rollers and equipped with cylinder opening and closing for easy operation. The internal heat conduction of the pressure rollers is used for heating. Glue two different materials together by heating.
Three storage areas are assembled using welded steel pipes to form a platform for easy transportation and disassembly. They are equipped with platform supports, tracks, lifting mechanisms, and buffering devices. When materials enter the buffering device to store materials, the lifting mechanism operates up and down vertically. The more materials are stored vertically, the less materials are stored vertically. During normal operation, the lifting mechanism is located at the bottom. When a new roll of material needs to be received at the unwinding area, it needs to pause for a short time, or when the winding area malfunctions, it needs to pause for a short time. The lifting mechanism runs upward,
The storage of buffer materials will automatically lower the lifting mechanism after the process is completed or after a brief fault is resolved.
Place the four cutting parts on the platform. Equipped with linear tracks, servo motors, and cutting blades.
5. Roll 1 # is assembled together with the cutting part for easy operation and transportation, using a conveyor belt friction structure. Equipped with drive rollers, conveyor belts, linear tracks, and shaftless loading mechanisms, it automatically moves left and right according to the width of the material, and operates up and down automatically according to the size of the material roll.
Place the 1 # conveyor mechanism on the back side to horizontally move materials for easy lifting
6 tension floating tension, equipped with a cylinder and swing arm mechanism, placed between the 2 # winding, automatically adjusts the tension compensation between the 2 # winding and the buffer zone distance.
7. The 2 # winding is placed on the platform, and the 2 # conveyor mechanism is placed on the back to horizontally move the material for easy lifting.
The process flow is as follows:;
S0 material is installed on the unwinding rack, and AB materials independently enter the pressure roller. After the pressure roller is heated and pressed, AB materials are bonded together to form a composite material.
S1 composite material enters the buffer storage rack. There are two ways of winding. If the nano aerogel felt is produced and has high temperature resistance and fluffy performance, 1 # winding is selected. 1 # winding uses conveyor belt surface friction, single station winding, no shaft loading and unloading structure, and the jacking mechanism on both sides moves synchronously from left to right, and the distance is adjusted according to the material width. With the change of the diameter of the coiled material, it automatically moves up and down, always keeping the material in contact with the conveyor belt.
S3, After the material reaches the set meter, the buffer storage mechanism automatically rises, and the cutting mechanism begins to operate. After the automatic cutting of the material is completed, it is removed by the 1 # conveyor platform and loaded and unloaded by the crane.
S4, If high temperature resistant aerogel sheet is produced. Choose the 2 # winding machine, which has a dual station of 4 rollers for winding. The surface friction method is used for winding, and there is a shaft loading and unloading structure. According to the width of the material, the paper tube is installed in advance on a fixed length inflatable shaft,
S5, After the material reaches the set meter, the buffer storage mechanism automatically rises, the cutting mechanism starts working, and the pressure roller mechanism presses the material. After the automatic cutting of the material at the cutting site is completed, the pushing mechanism removes the material to the unloading collection platform, which is operated by the 2 # conveying platform for removal, and the material is loaded and unloaded by the crane.
