72/96/120 Inch Latex Giant Balloon Round Big Balloon for Party Funny Game Hot Ballons Weather Balloo A Large Balloon

Commodity Description

Meteorological balloon is the use of natural latex as the main raw material, and then with the right amount of agent processing. Before use, after a certain amount of hydrogen is filled into the sphere, the buoyancy in the air is used to detect meteorological elements at different heights/carry a radiosonde to detect high-altitude meteorological elements.

Instructions for use:

1. overview:

Meteorological balloon is the use of natural latex as the main raw material, and then with the right amount of agent processing. Before use, after a certain amount of hydrogen is filled into the sphere, the buoyancy in the air is used to detect meteorological elements at different heights/carry a radiosonde to detect high-altitude meteorological elements.

2. Use Rules

Before use in winter, it should be placed in a room of not less than 10 ℃ for more than 24 hours; the storage temperature should not exceed 35 ℃.

2. Before inflation, the ground of the inflatable room must be cleaned. The ground should be covered or placed on a special inflatable table for inflation. The balloon cannot be directly placed on the ground for inflation. Do not make the ball skin contact with rough, sharp and claw objects (such as metal, stone, soil, rough board surface and other objects), and do not make the balloon explode in strong sunlight.

3. Before use/inflation, the ball skin should not be pulled and kneaded under pressure at will. It should be carefully and lightly placed on the ground cover/inflation table.

4, inflatable personnel must wear rubber/gauze gloves, so as to avoid fingernails or oil damage to the ball skin.

5. When the balloon starts to inflate, it should be slow, and the inflation flow should not be too large, so as not to cause violent friction between the ball skin and the ground cover/contact. After inflation, it should be released in time, and the stopping time should not exceed 30 minutes.

6. When charging, moisture and sundries must be prevented from being mixed (generally, hydrogen production by electrolysis should be adopted, and the purity of hydrogen should be above 99% as much as possible). The temperature of hydrogen charged shall not exceed 40 ℃.

7. Before inflation, the net lifting force and total lifting force shall be adjusted according to the weather conditions. The net lifting force shall be as close as possible to the specified indicators (see technical parameters of meteorological balloons) (special circumstances can be adjusted according to local experience indicators), and the balloon and the method shall be inflated to 20cm from the ground. The average speed of rise (related to net lifting force and weather conditions) is controlled as close as possible to the index (see technical parameters of meteorological balloon). The specific calculation method is as follows: total lifting force = balloon weight + balancer (commonly known as inflatable nozzle) weight + legal code weight net lifting force = total lifting force-balloon weight-sonde weight-lanyard weight is net lifting force = balancer weight + legal code weight-sonde weight-lanyard weight so that the required weight of the hanging code can be calculated. For example, the net lifting force should be controlled to 2000g, the weight of the pneumatic balancer to 1000g, the weight of the radiosonde to 450g, and the weight of the lanyard to 70g (these data can be determined before casting) to obtain the required legal code weight: legal code weight = 2000+450+70-1000=1520g.

Rules for transportation and storage of 3.

1. There must be a cover on the finished product box during transportation, and it is not allowed to be blown by wind, rain or sun.

2. It must be placed in a dry place during transportation and storage, and it is forbidden to contact/store with acid, alkali, oil flammable, copper, manganese and other metals or other substances harmful to rubber.

3. The balloon should be stored in a well-ventilated, cool and dry warehouse.

4, the balloon should be placed on a shelf more than 20cm from the ground, the stacking should not be too large, and there should be an appropriate distance between the stacks to maintain good ventilation.

5. Place the balloon 1 meter away from the heat source.

6. Balloons shall be turned over every 3 months during storage.

The storage period should not exceed 24 months. Note: Radiosonde (Radio sonde): an instrument carried by a balloon, equipped with sensors for measuring one or more meteorological variables (air pressure, temperature, humidity, etc.), passes through the atmosphere and transmits the detection signal to the observation station by means of a radio transmitter. A radiosonde can be attached to a 1 balloon or dropped from an aircraft or rocket (drop sonde). Sonding: The determination of one or more high-altitude meteorological variables by instruments carried by balloons, airplanes, kites, gliders, etc. High-altitude observations: Meteorological observations made in a direct or indirect manner in the free atmosphere.
