The use of gel thermal insulation cotton. The common aerogel thermal insulation material on the market now is aerogel thermal insulation board, also known as aerogel felt. It is mainly made of nano silica aerogel gel through special processes, with nano silica aerogel as the main material.
It has low thermal conductivity, certain tensile and compressive strength, and is convenient for thermal insulation construction and application. It belongs to a new nano thermal insulation material. This material is mainly used in industrial pipelines, storage tanks, industrial furnaces, power plants, life saving cabins, warship bulkheads, etc. It can be said that it is widely used.
1、 Introduction of aerogel insulation cotton
Aerogel nano thermal insulation foam is a new type of nano thermal insulation material, which helps the electronics industry, new energy batteries, automotive industry, shipbuilding and military industry and other industries to solve the needs of thermal insulation and fire prevention, cushioning and shock absorption, sound insulation and noise reduction, lightweight, etc. It can be compounded with graphite sheet, copper foil, aluminum foil and other thermal conductive and heat dissipating materials, with one side conducting heat and the other side insulating and buffering, to meet the actual needs of customers in a variety of different use scenarios.
2、 Characteristics of aerogel insulation cotton
1. The porosity is very high, up to 99.8%;
2. Nanoscale pores (20~100nm) and three-dimensional nano skeleton particles (2~5nm);
3. High specific surface area, up to 1000m2/g;
4. Low density, as low as 0.003g/cm3;
5. The unique structure of aerogel determines its extremely low thermal conductivity, which can be as low as 0.013W/(m · K) at room temperature;
6. It has low strength and high brittleness. Due to its large specific surface area, porosity and low density, its strength is very low.
3、 Performance and application of aerogel insulation cotton:
Aerogels have been widely used due to their characteristics. For example, nano sized pores in aerogels can collect various pollutants like sponges. Bob, a Nottingham native in England, has a house insulated with aerogel, and the heat preservation effect of the house has been greatly improved. Mountaineers wearing hiking boots with air gel thermal insulation insoles only feel the soles of their feet are too hot when climbing Mount Everest. Aerogel can also be used as catalyst carrier, super adiabatic combustion carrier, combustion substance (similar to solid alcohol) that can be used in severe weather conditions, combination with fuel cell technology, and photocatalyst carrier.
4、 Air gel insulation cotton double-sided adhesive equipment
Qin-tech qi gel heat insulation cotton double-sided adhesive device is an automatic device for pasting double-sided adhesive on the air gel heat insulation cotton, which can save labor and improve the pasting efficiency. 1. Dock with other equipment of the customer for automatic feeding, with compact design and small floor area;
2. The equipment is divided into front and rear modules, and the front equipment is pasted with double-sided adhesive tape on the front of thermal insulation cotton; The rear end equipment pastes the reverse double-sided adhesive tape and the release paper tear off handle, pre tear the release paper, flatten the release paper twice, and automatically blanking;
3. Independent control system of front and rear equipment;
4. The compatible size of the product is large: maximum 250 * 250mm, minimum 80 * 80mm;
5. The equipment has two sets of high-precision CCD to ensure the mounting accuracy of double-sided adhesive tape, which can achieve a repeated mounting accuracy of ± 0.2mm;
6. Automatic binding machine can be selected to achieve automatic binding and packaging, improve the efficiency of manual operation and reduce labor.
