200 Micron UV Resistant Plastic

200 micron UV resistant plastic product description:

Greenhouse film is a film constructed in agricultural production. It has the characteristics of light transmittance, heat preservation, tensile resistance and aging resistance. It is often used in farming, so the demand is high. There are many materials for greenhouse films, and the prices of different materials vary. So how much does a kilogram of greenhouse film generally cost? Let’s learn about the types, advantages and disadvantages of various greenhouse films.

1. PVC (polyvinyl chloride) shed film

Advantages: good light transmittance, the new film has a total light transmittance of more than 85%, excellent moisture retention, low thermal conductivity, high tensile strength, and strong wind resistance. Good chemical stability, acid and alkali resistance.

Disadvantages: It is easy to vacuum and difficult to clean. After vacuuming, the light transmittance of the greenhouse film is seriously affected. It is not suitable for use in areas with large winds and dust. The greenhouse film becomes loose during high temperatures in summer and its wind resistance is weakened. The price is relatively high. High, which increases the production cost; the residual film pollutes the soil greatly and cannot be burned, so the current usage is gradually decreasing.

The main products are: ordinary PVC shed film, PVC anti-aging film, PVC non-drip anti-aging film, PVC weather-resistant non-drip and dust-proof film, etc.

2. PE shed film

Advantages: light texture, soft, easy to shape, good light transmittance, non-toxic, suitable for various greenhouse films and mulch films, and is currently the main agricultural film variety in my country.

Disadvantages: poor weather resistance, poor thermal insulation, and difficult to bond.

The main varieties include: ordinary PE shed film, PE anti-aging film, PE drip-free anti-aging film, PE multi-functional composite film, etc.

3. Grout film

Advantages: The functional dripping anti-fog agent tightly adheres to the inner wall of the shed film and forms a layer of agent on the inner surface of the shed film. As soon as the moisture in the shed contacts the inner wall of the shed membrane, a layer of water film will be formed, and then flow down the slope of the shed due to its own gravity, thereby achieving the effect of eliminating fog and dripping.

Disadvantages: The anti-fog dripping agent is attached to the surface of the agricultural film, so the adhesion is not that strong. External forces can easily damage the coating, and it is easy to cause dripping in the damaged areas. It is difficult to use grouting film on crops that like high temperature and high humidity, such as cucumbers, bitter melons, melons, etc.

4. EVA film

Advantages: It is a greenhouse plastic film that is currently used in large quantities. This type of film has super light transmittance, with a light transmittance of more than 92%; it has excellent dripping and fog elimination properties, and the dripping period is 4-6 months More than 18 months; has excellent thermal insulation, dustproof and super aging resistance (more than 18 months).

Disadvantages: higher price.

The main varieties include: EVA drip-free, anti-aging, high thermal insulation greenhouse film, EVA multi-functional composite greenhouse film, etc.

5. PO film

It is a new type of film developed in recent years. This type of film is a functional polyolefin agricultural film produced from polyolefin. Its light transmittance, continuous fog elimination, dripping property, and thermal insulation properties are among the best in shed films. Among them, it is in the leading position and has high cost performance. It is a type of film with great promotion prospects. At present, the thickness of PO film ranges from 8 filaments, 12 filaments, and 15 filaments.

There are roughly two types of greenhouse films, one is colorless and the other is blue. The white shed film will reflect red-orange light and yellow light. Pests such as whiteflies and aphids have yellow tendency, so they will attract pests. Blue greenhouse film will reflect blue-violet light, which is detrimental to the coloring of solanaceous vegetables. Everyone can choose according to their actual situation.

The main products are: 8-filament PO film, 12-filament PO film, 15-filament PO film, etc.

6. Adjustable shed film (functional film)

The dimmable agricultural film is made by adding rare earths and other functional additives to PE resin. It can selectively transmit light and is a new covering material that can make full use of solar energy. Compared with other greenhouse films, it has good warming and insulation effects in the greenhouse, strong biochemical effects on crops, and has the functions of early maturity, high yield, and improved nutritional content for different crops. Mainly suitable for the cultivation of leeks and various green leafy vegetables.

Single San/ tunnel greenhouse has a modern and novel in exterior, and has a stable structure. It adopts hot galvanized pipes connected by the hot-galvanizing bolts and tapping screws, without any welding point. So it is strong and practical and also simple beautiful in overall.

Main parameter index

The main configuration

1. Internal shading of 200 Micron UV Resistant Plastic: Setting internal shading is an effective way to save energy, shade, temperature and humidity.

2. Outside shading: In summer, the solar radiation heat load is too high,when the external shading system is used, the indoor temperature can be controlled to be only 1ºChigher than that of the outdoor room in a well ventilated greenhouse due to the blocking of most of the solar radiation into the greenhouse.

3. Exhust fan: Reasonable design, low noise, big air volume, strong wind, low operation cost.

4. Cooling pad: Corrugated paper uses space cross-linking technology, which make it with high water absorption, high water resistant, mildew resistance, corrosion resistance, long service life. 

5. Water treatment: Rare flowers and plants have very high request for its irrigation water.

6. Irrigation system: Sprinkler irrigation System:It use high-pressure pump for irrigation by spray system, which sprays water on the crops, is a method of irrigation water for the normal growth. It is a modern agricultural production technology collecting irrigation, fertilization and automation management. It can be divided into mobile pattern or sprinkler fixed irrigation system or half fixed spray irrigation system. 

7. Natural ventilation system: keep  air circulation inside and outside the greenhouse (Must be installed)

8. heating system-Suitable for cold weather countries (optional)

9. Hydroponic system(NFT system)

Advantages

1. lt’s skeleton s made of hot - galvanizing steel . strong and durable and beautiful in overall .

2. The covering material is film . It has a good performance in the transmittance sealing , insulation and ornamental 

3. Large light area , uniform illumination

4. Big inner space for operation , high utilization , good bandwagon effect .
