Anti-fogging film

Anti-fogging film is a special plastic film used in greenhouses. Its main function is to prevent water vapor on the inner surface of greenhouses from condensing into water droplets. This condensation often causes disease on plant foliage and reduces light transmittance, which affects crop growth. Anti-fogging film changes the surface tension of the film through its special surface treatment or additives, so that water vapor is not easy to condense into large water droplets on the surface of the film, but forms a uniform water film, so that water can flow down the surface of the film and enter the drainage system, rather than remain in the greenhouse in the form of water droplets.

The working principle of anti-fogging film usually includes the following aspects:

1.Change of surface tension: By adding specific surfactants or coatings to the film, the surface tension of the film is changed, so that water molecules are not easy to form large water droplets on the surface.
2. Formation of ultra-thin water film: Due to the change of surface tension, water molecules spread out on the surface of the film to form a very thin water film, which can cover the film evenly instead of forming independent water droplets.
3.Water diversion: This ultra-thin water film can flow along the inclined surface of the film and eventually into the drainage system of the greenhouse, thus keeping the interior of the greenhouse dry and clean.
4.Anti-fog effect: The anti-fog film can also reduce the fog inside the greenhouse and improve the light transmittance, which is very important for the photosynthesis and growth of plants.

The effectiveness of the anti-fogging film can be affected by time and environmental conditions, and may require periodic replacement or maintenance of the surface treatment to maintain its optimum performance. In greenhouse management and plant cultivation, the use of anti-drip film can improve crop yield and quality, while reducing the occurrence of diseases.

Different varieties of seedlings and growth stages need different light conditions, so it is necessary to regulate and use light related equipment and facilities reasonably. Illumination control facilities include plant lights, plant supplementary lights, etc.

2.Temperature control facilities

The temperature in the greenhouse should be within a suitable range to promote the healthy growth of seedlings. Temperature control facilities include heating equipment and ventilation equipment.
Heating equipment can be heated by electric heater, hot water pipeline, gas, etc.
Ventilation equipment mainly includes exhaust fans, side windows and skylights. The use of exhaust fans can effectively regulate the temperature and humidity and prevent the growth of mold. The opening of the side window and the skylight can increase the air circulation, promote the entry of CO2 and the discharge of O2, thereby promoting the growth and development of the seedlings.

3.Humidity control facilities

The environmental control facilities of seedling greenhouse are very important for the growth, development and quality of seedlings. The use of various environmental control facilities should be reasonably regulated according to the needs of different seedlings and different growth stages, so as to ensure that the environmental indicators in the seedling greenhouse are within the appropriate range and promote the healthy growth of seedlings.

Welcome to Qingzhou Juxiang Agricultural Equipment Co., Ltd.!

Our cutting-edge glass greenhouse ventilation system is meticulously crafted to enhance plant growth by efficiently managing temperature, humidity, and air quality. Say goodbye to waste heat, moisture, and harmful gases with our system, creating the perfect environment for your plants to flourish.

Natural ventilation glass greenhouse relies on natural ventilation to regulate the indoor environment most of the time. The structural form of large productive glass greenhouse is generally double-slope multi-span greenhouse, and the ventilation form is to set ventilation windows on the side wall and roof ridge. Its total ventilation area is not less than 15% of the greenhouse area, preferably more than 30%. When the roof wind window is opened, the window sash should be inclined upward beyond the horizontal plane. When it is fully opened, it forms an angle of 100 with the horizontal plane, which can achieve good ventilation effect.

2.Forced ventilation glass greenhouses rely on natural ventilation to regulate the environment most of the time, when the temperature is high in summer, especially when the outdoor temperature is over 33 ºC, it is difficult to meet the cooling requirements of greenhouses by natural ventilation alone, so forced ventilation and other measures are commonly used in production. Forced ventilation is to use fans to convert electric energy or other mechanical energy into wind energy, forcing air flow to ventilate the greenhouse and achieve cooling effect.

1.Hot water heating The hot water heating system is composed of three basic parts: hot water boiler, heat supply pipe and heat dissipation equipment. Its working process is to heat water with the boiler and then pressurize it with the water pump. The hot water is supplied to the radiator in the greenhouse through the heat supply pipe. The radiator is used to heat and raise the temperature of the greenhouse. The cooled hot water is returned to the boiler for reheating and repeated circulation. The hot water heating system is stable and reliable, which is the most commonly used heating mode in glass greenhouse.
2.hot air heat system Consists of a heat source, an air heat exchange, a fan and an air supply pipeline. Its working process is as follows: the air exchanger is heated by the heat provided by the heat source, and the fan is used to force part of the air in the greenhouse to flow through the air heat exchanger, so that the greenhouse is heated by continuous circulation. The heat source of the hot air heating system can be oil, gas, coal-fired devices or electric heaters, and can also be hot water or steam. The installation forms of hot air heating equipment are different for different heat sources.
3.Electric Heating The more common way of electric heating is to bury the ground heating wire underground

Company name: Qingzhou Juxiang Agricultural Equipment Co., Ltd.

Welcome to Qingzhou Juxiang Agricultural Equipment Co., Ltd.

Product Description:

Our evaporative cooling system utilizes the unsaturation of air and the latent heat of evaporation of water to effectively cool down greenhouses. By evaporating moisture into water vapor, heat is absorbed from the air, reducing temperatures and increasing humidity. Proper air flow management is essential for optimal performance, achieved through forced ventilation methods like wet curtain-fan cooling and spray cooling.

The roof spray cooling system evenly sprays water on the greenhouse roof, facilitating heat exchange with the glass roof and effectively reducing internal temperatures. When the water film thickness exceeds 0.2 mm, it absorbs solar radiation energy, providing shading benefits.
