Proportion of low temperature antifreeze liquid A glycol aqueous solution: ethylene glycol / water 55/45 (-30 ° C), 70/30 (-40 ° C) B glycerol aqueous solution: glycerin / water 70/30 (- 30 ℃) The density of low-temperature antifreeze should be checked frequently during use to meet the following requirements: 1. Ethylene glycol aqueous solution: P20 = 1079㎠/ m3 (-30 ° C) (-40 ° C) 2. Glycerin aqueous solution: P20 = 1182.6㎠/ m3 (-30 ℃) When the antifreeze is replaced with water, the minimum temperature must be above 0 ℃. Cooling water type selection: Generally, small-scale circulating water cooling thermostats with cooling capacity below 1000W are widely used in laboratory condensing devices such as low-power lasers, parallel evaporators, parallel quantitative concentrators, parallel reactors, and distillers. Medium-sized circulating water-cooled thermostats with a refrigeration capacity below 6000W are widely used in analytical instruments such as AAS, ICP, ICP-MS, and electron microscopy. Rotary evaporators, Soxhlet extraction, solid-liquid extraction instruments, Kjeldahl nitrogen determination instruments , Laser marking machine, laser cutting machine and other laser instruments and machine tool industries. Large-scale circulating water-cooled thermostats with a refrigeration capacity of more than 10KW are widely used in X-diffraction instruments, magnetic mass spectrometers, fatigue testing machines, vacuum coating machines, plastic forming equipment, laser cutting machines, X-fluorescence spectrometers, infrared spectrometers, and differential thermal analysis Instruments, nuclear magnetic resonance and other equipment with high refrigeration constant temperature requirements.

The water tank can be cooled with high-quality pure water inside and outside the machine, which can ensure the normal operation of precision instruments with high water quality requirements and extend the service life of precision instruments.
Outdoor bench refers to the seating facilities used in outdoor places, often commonly found in parks, squares, leisure areas, scenic spots and other outdoor environments. The classification of outdoor benches can be introduced according to many aspects such as material, shape and function.
First, classification by material
1. Wooden bench: Wooden bench is one of the most common outdoor benches, usually made of natural wood, with natural and environmentally friendly characteristics. Wooden benches are usually made of solid wood or artificial wood, and the surface is treated with waterproof and anti-corrosion, which can adapt to various climatic conditions in the outdoor environment.
2. Metal bench: Metal bench is made of metal materials, such as cast iron, steel, etc. The metal bench is durable, corrosion resistant, easy to clean and is suitable for all kinds of outdoor environments.
3. Stone bench: Stone bench is made of marble, granite and other stone, which has the characteristics of good texture and beautiful appearance. Stone benches are generally suitable for high-end places such as garden scenic spots and can be integrated with the surrounding environment.
5. Combined material bench: Combined material bench refers to the bench made of different materials, such as the combination of wood and metal, stone and plastic combination. Combined material bench can usually combine the advantages of different materials, more in line with the needs of different outdoor environments.
2. Classification by shape
1. Linear bench: Linear bench is the most common shape of bench, generally composed of a row of seats, forming a straight line arrangement. The linear bench is suitable for outdoor places with large pedestrian flow and can provide more seats.
2. Arc bench: Arc bench is an arc bench composed of multiple seats, usually used in a ring seat area or landscape area. The curved bench can not only provide comfortable seating, but also increase the aesthetics of the place.
3. Wavy bench: The wavy bench is a bench composed of multiple seats in the shape of undulating waves, giving people a sense of movement and flow. The wavy bench is suitable for parks, squares and other places that need to increase vitality and fun.
4. Round bench: A round bench is a round bench composed of a number of seats, which is usually used in outdoor recreation areas and can provide a place for groups to gather.
3. Classification by function
1. Leisure bench: Leisure bench is a common form of outdoor bench, it can provide comfortable seats, so that people can relax in the outdoor environment.
2. Viewing bench: Viewing bench is usually set in a scenic outdoor environment, providing comfortable seats for people to enjoy the scenery.
3. Sitting bench: Sitting bench is usually set in parks, squares and other places with large traffic, to provide people with a short rest and relaxation.
4. Cool pavilion bench: Pavilion bench refers to a form of combination of bench and pavilion, which can provide sunshade, rain prevention and other functions, suitable for outdoor leisure areas.
In short, the classification of outdoor benches can be divided from many aspects such as material, shape and function. Different outdoor environments and needs need to choose a suitable bench type to provide comfortable and beautiful seating facilities
