What are the benefits of black and white film besides the price

Because of the provisions of edible bacteria on temperature, air relative humidity, vapor and air circulation (permeability rate), sunlight exposure, at present, people generally use transparent longevity film covered with layers of sunscreen net greenhouse vegetables to grow edible bacteria, such cover raw materials every 2-3 years disassembly several times each time the direct cost of 2-3 yuan/square meter, although it can also take into account production But it is not rational, due to the longevity of the film light transmittance high vault heating rapid night cooling fast, so the vault temperature is high dry, more importantly, this kind of plastic film suitable for light-loving fruits and vegetables pot green plant food crops itself permeability rate (fruit and vegetables pot green plant is the digestion of co2 production and processing co2 and relative edible bacteria is digestion of co2 Production and processing of co2, so the black and white film on the edible bacteria bacteria on the plastic film permeability rate has higher requirements) is not suitable for edible bacteria cultivation (so it is covered with layers of sunscreen net), although the sunscreen net can block most of the sun, but when the sunscreen net digestion of the mechanical energy is saturated, the excess mechanical energy is still radioactive material to the film to make the vault temperature is high, so this kind of node The greenhouse vegetables cannot take into account the requirements of edible fungi on temperature, air relative humidity, vapor and air circulation (permeability)! In turn, production and quality are jeopardized.

So whether to consider the edible bacteria in the ideal temperature, environmental humidity, gas and natural ventilation (permeability), sunlight natural environment growth and development can be as large-scale production of four seasons? The answer is no doubt, and the one that can consider this standard is a two-color film called "edible fungi special black and white film"! Its continuous application has reached more than five years!

This kind of plastic film is a special black and white film for cultivation and cultivation introduced in India, white and black inside, if used in spring and summer seasons, the white color faces up when covered, with vertical professional ability, and black and gray inward resistance to light source penetration, with light blocking and cooling effect, the temperature of the arch is much lower than that covered by other waterproof canvas and plastic film. Together, there is a strong expected effect of preventing disease and insect infestation.

This kind of plastic film has a high thermoelectric effect to ensure that the ground temperature at night and in winter has a good thermal insulation and insulation effect, reducing the temperature difference. Thermoelectric effect (IR): it refers to the professional ability to maintain the heat value temperature in the film at night or in winter, under the ground low temperature geographical environment. The measurement company of thermoelectric effect is IR,(Infraredradiations/ infrared sensing radioactive substances) transmission length, which is how long the spectrum analyzer is allowed to pass through this plastic film. In other words, the larger the IR, the smaller the calorific value, in general, the thermoelectric effect is created by the inner layer (black-gray layer), the astigmatic eye rate (light scattering) is created by the surface (milky white layer), the inner layer digesces and blocks the infrared sensors escaping from the soil layer, and the scattering effect will return it vertically into the soil layer to exceed the expected effect of thermal insulation. The inner layer of the plastic film is a variable light layer, whose effect is to transform the light that crops or animals do not need into a reasonable light, so as to improve the economic benefits of breeding, and the inner layer also has the effect of heat insulation to ensure that the arch shed cools in summer, winter and night heat insulation.

The scope of application is very wide such as edible fungi greenhouse; Silkworm and vegetable greenhouses; Cover layer of aquaculture shed, water barrier layer of hydroponic planting; The surface of the vegetable greenhouse is heat insulation, anti-freezing, and the subfilm of the vegetable in the greenhouse; Pellet feed storage feed storage quality guarantee period, agricultural and sideline products frozen storage (such as potato); Animal husbandry, animal husbandry (such as breeding houses, breeding industry houses...) Potted green plants block light, break light (to adjust the flowering period), etc., for the cultivation of plants and green plants its total output and quality will be multiplied! In addition, it has the actual effect of strong disease prevention growth and development, because the unique structure of the black and white film makes the shed gas in the humidity control situation for a long time and can improve the circulation and permeability of the arch shed gas to ensure that the posture object grows and develops in a more comfortable natural environment.
