What kind of greenhouse film do you have?

With the application and promotion of greenhouse planting technology, greenhouse film products are more and more widely used in agricultural production, and most greenhouse film structures tend to compound development, and the performance is more comprehensive, such as light transmission, heat preservation, long life and so on. Of course, the characteristics of different types of greenhouse film are also different, so farmers must distinguish clearly before using it. So what kind of greenhouse film do you have? Let's get to know it.

Polyvinyl chloride (PVC) greenhouse film

1. Advantages: good light transmittance (the full light transmittance of the new film is more than 85%), excellent moisture retention, low thermal conductivity, high tensile strength and strong wind resistance.

2, disadvantages: the film has a large proportion, the same area of the greenhouse, its use than polyethylene increased by 1 stroke 3, resulting in an increase in cost. In addition, the film surface is easy to dust, generally after a month of use, the light transmittance is very poor, the residual film pollutes the soil and can not be burned.

The main products are: ordinary PVC greenhouse film, PVC anti-aging film, PVC no-drop anti-aging film, PVC weather-resistant no-drop anti-dust film and so on.

Polyethylene (PE) greenhouse film

1. Advantages: light, soft, easy to shape, good light transmittance, non-toxic, suitable for all kinds of greenhouse film and mulch film, is the main variety of agricultural film in China.

2, disadvantages: poor weather resistance, poor thermal insulation, not easy to bond.

The main varieties are: ordinary PE greenhouse film, PE anti-aging film, PE non-dropping anti-aging film, PE multi-functional composite film and so on.

Ethylene-vinyl acetate copolymer (EVA) greenhouse film

1. Advantages: strong light transmittance, excellent droplet antifogging, dripping period of more than 4-6 months, and excellent thermal insulation, dustproof and aging resistance.

2. Disadvantages: the price is higher.

The main varieties are: EVA non-drop anti-aging high thermal insulation greenhouse film, EVA multi-functional composite greenhouse film and so on.

Dimming greenhouse film (functional film)

Dimming agricultural film is made by adding rare earth and other functional auxiliaries to PE resin, which can selectively pass through light and is a new covering material that can make full use of solar energy. Compared with other greenhouse films, the warming and heat preservation effect in the greenhouse is better, and the biochemical effect of crops is strong, which has the functions of early maturity, high yield and improving nutrition for different crops. It is mainly suitable for the cultivation of leek and many kinds of green leafy vegetables.

Propylene oxide (PO) greenhouse film

PO film is also a new type of film developed in recent years. This kind of film is a high-grade functional polyolefin agricultural film produced by polyolefin. Its light transmittance, continuous anti-fog, dripping, heat preservation and so on, it is in a leading position in the greenhouse film with high performance and price.

The main products are: 8 wire PO film, 12 wire PO film, 15 wire PO film and so on.

Phellodendron mandshurica (Thunb.)

At present, all kinds of greenhouse films can be seen in the daily application from the traditional ground insertion arch greenhouse, solar greenhouse, double-sided slope greenhouse, multi-span film greenhouse and fungus greenhouse. The above five kinds of greenhouse film have similarities and differences in nature, so the use effect is also different, farmers must combine the characteristics of greenhouse film to choose appropriate products.
