The plastic film thickness of 12 filament is 0. 12 mm, which is expressed as "filament". 1 mm = 100 filament, 0.0 1 mm = 1 filament. The performance of greenhouse film is better than that of ordinary film in terms of heat preservation, tensile strength and aging resistance. After use, it can promote crop growth and increase production and income. There are four kinds of greenhouse films commonly used in China, which are polyvinyl chloride (PVC) greenhouse film, ethylene-vinyl acetate copolymer greenhouse film, polyethylene (PE) greenhouse film and dimming agricultural film.

How thick is the greenhouse film of 1. 12s?

The film thickness of 1 and 12 in greenhouse is 0. 12 mm ... The film thickness in greenhouse is expressed by "silk", 100 silk = 1 mm, 1 silk = 0.0/kloc.

2. When agricultural production is carried out in greenhouse, 8- 10 silk film is usually used, and 6 silk film is rarely used.

3. The performance of greenhouse film is better than that of ordinary film in terms of heat preservation, tensile strength, aging resistance and light transmittance. After use, it can promote the growth of crops and achieve the purpose of increasing production and income.

4. There are four commonly used greenhouse films in China, namely PVC greenhouse film, dimming agricultural film, ethylene-vinyl acetate copolymer greenhouse film and polyethylene (PE) greenhouse film.

5. When building a greenhouse, we should choose different greenhouse films according to different crops, so as to achieve the ideal effect. If the greenhouse membrane is not selected properly, the crops may be in an anoxic environment.

2. Is the greenhouse film blue or white?

1, the white film is usually better than the blue film, because the white film has better light transmission and lighting, which can make the temperature in the shed rise rapidly.

2. Ordinary PE shed film is directly blown into white film with raw materials without additives (such as anti-aging). This kind of greenhouse film is widely used in greenhouses and small and medium-sized greenhouses. The use cycle in spring and autumn is only 4-6 months, and only one crop can be planted, which has been gradually eliminated.

3.PE anti-aging film is made by adding anti-aging additives to PE resin and blow molding. The film thickness is generally 0.08-0. 12 mm, and its service life reaches 12- 18 months, so it can be used for planting 2-3 crops. This kind of greenhouse film can improve the yield and output value, and it is the key agricultural film variety for equipment cultivation.

4.PE insulation film can prevent infrared radiation in the greenhouse from radiating into the atmosphere, and increase the greenhouse temperature by 1-2℃, which is suitable for use in relatively cold areas.
