chemical absorbs heat, then lower the temperature (Endothermic chemicals)
, this kind of chemical reaction will absorb moisture and keep the temperature down. We use this chemical to effectively absorb moisture, then the solution became dark. Concentrated at a temperature below the temperature which causes condensation in the condensation higher. The growth of tablets and water in clouds is larger, faster and latent heat released by the condensation will cause the rise of air masses and. The distillation process continues. In addition, the movement and integration of large grain imports to grow up to be added in the distillation process fatten. And the movement of grain and water to grow larger until the surface tension (Surface tension) can not be fixed size. The rise or fall against the wind. The larger the grain imports. It distinguishes itself as a smaller tablet. Increase the condensing solution diluted concentrations floating back up to the new prosperity. And grow into a large grain imports into the rain. Or dissociated continuous chain reaction. Mechanisms or processes such as enlargement clouds increase and higher (Rain enhancement) currently operating in the chemical sector are three types:
(1) Urea (Urea; Co (NH2) 2) once. absorb moisture and absorbs heat from 10.57 kcal per molecule. And become the condensation (nuclei), a substance that is sensitive to moisture on the skin (Surface active material) high growth of water droplets in clouds become water droplets with a larger one
(2. ) ammonium nitrate (Ammoniumnitrate; NH4NO3) when it absorbs moisture absorption heat equal to 6.30 kcal per molecule. And become the condensation as well as urea. In that case, state water vapor or clouds that will rain fell. We help pull heat out by the absorption of substances
(3), dry ice (Dry ice; CO2 (s)) used in grinding flakes. Or a mass of less than one cubic inch is a substance that is produced from carbon dioxide. The processed under high pressure. The status solidification When in the normal pressure Absorbs heat from the evaporator turns

solid carbon dioxide (CO2) has temperatures below freezing to -78 degrees Celsius conditions, water vapor condensation and frost have become to absorb the chemicals. The only moisture chemical reaction occurs when the temperature changes very little. It serves as the condensation. And became the condensing a concentrated solution. The substance is used in all stages of a disruptive process. Fatten and attack from the distillation process will lose its heat. The buoyancy of the air mass causing the continuous distillation same. Chemical These include (1) salt (Sodium chloride; NaCl) used in today's sea salt that has been developed into a fine powder with particle sizes ranging from 10 Wood - Akron and up to 100 microns absorb. humidity The reaction NaCl + aq (water) Na + k (AQ) + Cl- (AQ) (2) chemical formula unit. 1 is a chemical that is a mixture of many compounds and the latest research. Substances used in operating now in the form of sodium chloride crystals in the form of mineral Eฮalts (Halite), unlike crystals of sea salt plain no less than 50% and is in the form of other compounds as well. ferric oxide (Fe2O3) in the form of hematite ore (Hematite) silicon - dioxide (SiO2) in the form of the mineral quartz fiber. (Quartz), magnesium sulfate (MgSO4.7H20) in the form of crystalline water. Aluminum chloride (AlCl3) and magnesium chloride (MgCl2) of not less than 10%, which absorbs moisture in the air. To qualify as core refining the solution concentration of not less than 50%, also as the condensing a hard core of not less than 10% and has been developed with a particle size ranging from 10 microns to less than 180 microns is. saturated solution with the conductor (Electrical conductivity) up to 510 12 mmol. This will enhance the efficiency of condensation. The combination of water and grain growth in the movement of grain and loaves cloudy water up to make artificial rain or rain water from the sky is the process of induction. Use aircraft to scatter chemicals in the sky. By moisture, clouds and wind complement each other. Important factors that caused the rain. Moist heat impingement cooling And the condensation efficiency is the right amount when humid air mass at the surface up into the sky above. The air temperature will be lowered to a height level. If the temperature is low enough that it makes the water vapor in the air is saturated. Refining processes themselves are born of water vapor in the air condenses on the axis. As rain If chemicals are used, it includes "hot formula" pusher mechanism used to stimulate the circulation of the atmosphere, "a formula" a mechanism to stimulate the integration of cloud droplets grow to become raindrops. And the formula used to absorb moisture. To stimulate the condensation mechanism for more efficient procedures Rain Step one: "Harry is a natural step to cloud formation vertically. Operations at this stage aimed at encouraging the use of chemicals floating up into the air above. To achieve induction process steam or moisture to the cloud. Time to perform this step should not exceed 10.00 hrs. Of the day by using chemicals that can absorb water vapor from the air. Despite the low percentage of relative humidity (critical relative humidity is low) to stimulate the mechanism of condensing steam in the air. (Create a suitable environment for the growth of cloud with) the windward side of the goal area. When the clouds are forming and growing the already set. The chemical reaction that gives off heat and rain, a circle or a line next to the wind under a short distance into the clouds. To motivate
