Problems solved by technology

Flame retardant is a functional additive that imparts flame retardancy to flammable polymers. It has been widely used in coal mines, construction, plastic products, etc., but it is rarely used for fire protection in forests and grasslands. On the one hand, it is a flame retardant material. The shape and use method limit the scope of use. On the other hand, some materials themselves or their reaction products may cause environmental pollution.

Embodiment 1

[0030] Two balls and one line: Two temperature-controlled aftercoat balls are connected by an aramid thread, and the throwing experiment is carried out on a slope of 1:4. The slope is smooth and the ground is smooth. The specific experimental method is as follows:

[0031] 1) Cut glass fiber threads of suitable length. Aramid threads have low water absorption and low shrinkage rate. In order to make the connection stronger, put the two ends of them into two spherical moulds;

[0032] 2) Prepare 20% calcium chloride solution, drop it into the mold containing the aramid thread with a plastic dropper, and then put it into the refrigerator or liquid nitrogen to freeze;

[0033] 3) Weigh the temperature-controlled cell coat material in a corresponding proportion and put it into a beaker, and put the beaker into a constant temperature water bath with a temperature of 80°C to heat and melt;

[0034] 4) The frozen ice balls in 2) are connected in pairs) and wrapped with molten shell ...

Embodiment 2

[0037] Two balls and one line: Two temperature-controlled aftercoat balls are connected by an aramid thread, and the throwing experiment is carried out on a slope of 2:3. The slope is smooth and the ground is smooth. The specific experimental method is as follows:

[0038] 1) Cut glass fiber threads of suitable length. Aramid threads have low water absorption and low shrinkage rate. In order to make the connection stronger, put the two ends of them into two spherical moulds;

[0039] 2) Prepare 20% calcium chloride solution, drop it into the mold containing the aramid thread with a plastic dropper, and then put it into the refrigerator or liquid nitrogen to freeze;

[0040] 3) Weigh the temperature-controlled cell coat material in a corresponding proportion and put it into a beaker, and put the beaker into a constant temperature water bath with a temperature of 80°C to heat and melt;

Embodiment 3

[0044] Two balls and one line: Two temperature-controlled aftercoat balls are connected by an aramid thread, and the tossing experiment is carried out on an outdoor grass field with complex terrain. The specific experimental method is as follows:

[0045] 1) Cut glass fiber threads of suitable length. Aramid threads have low water absorption and low shrinkage rate. In order to make the connection stronger, put the two ends of them into two spherical moulds;

[0046] 2) Prepare 20% calcium chloride solution, drop it into the mold containing the aramid thread with a plastic dropper, and then put it into the refrigerator or liquid nitrogen to freeze;

[0047] 3) Weigh the temperature-controlled cell coat material in a corresponding proportion and put it into a beaker, and put the beaker into a constant temperature water bath with a temperature of 80°C to heat and melt;

Abstract

The invention provides a connection type temperature control cell coating inhibition ball for forest and grassland fire prevention and a use method, and is suitable for forest or grassland fire prevention and extinguishment. The connection type temperature control cell coating inhibition ball comprises flame-retardant pellets and aramid fibers, each flame-retardant pellet is composed of a coating shell and an internal inhibition liquid, the coating shell comprises a phase-change material and a reinforcement material, the phase-change material and the reinforcement material can be converted into a liquid state from a solid state within a certain temperature range after being melted, mixed and formed, the inhibition liquid sealed in the interior is released, and the inhibition liquid is generally a 20% calcium chloride solution. The aramid fibers are high-temperature-resistant, high-strength, superfine and flexible special fibers. According to a device, the flame-retardant pellets and the aramid fibers are combined, the rolling area of the flame-retardant pellets is purposefully limited through the traction effect of the aramid fibers, the inhibition balls are more concentrated in the throwing process, the influence of the throwing terrain on the effect of the flame-retardant pellets is reduced, and therefore the utilization rate of the inhibition balls is increased, and the flame-retardant effect is more efficiently achieved.

Description

technical field [0001] The invention relates to a temperature-controlled cell coat chemical resistance ball and a use method thereof, in particular to a connected temperature-controlled cell coat chemical resistance ball used for forest and grassland fire protection and a use method thereof. Background technique [0002] With the continuous progress and development of society, while people are pursuing advanced technology, their awareness of environmental protection is also increasing. Therefore, the protection of forest and grassland fires has become the focus and difficulty of work in various countries and regions. For this reason, the government has successively A variety of protective measures and corresponding technical means have been introduced, the ultimate goal is to promote the formation of a fire isolation zone, such as eliminating combustibles in advance to avoid further expansion of the fire. Relevant scholars have analyzed a large number of forest fire cases an...
