Supply of greenhouse films, EVA film, PO film

Ethylene - vinyl acetate polymer (EVA film) Purpose: winter-type greenhouse, shed Thickness: 7 wire -12 Esther sex: EVA film ethylene - vinyl acetate copolymer (EVA) as the base material, a thin film of VA content directly affect the performance of the film, with high insulation resistance, low temperature, high longevity, puncture resistance, tear resistance, good flexibility, fog drip characteristics of a long period. Suitable for the cultivation of crops: suitable for planting vegetables PVC (pvc) films PVC films are known for high temperature membrane uses: Winter style Greenhouse Thickness: 10 wire above characteristics: it is in the polyvinyl chloride resin added plasticizers, stabilizers, lubricants, functional additives and processing aids, calendered film. Better insulation properties of such plastic sheeting, used for the hi hot vegetables, PVC films with good transparency, but dust and strong, difficult to clean, light transmission rate has dropped fast. Night stronger than polyethylene insulation film, because of its infrared transmission rate, and the sun and heat, tensile strength, elongation Zhang Liqiang, more durable, lighter fog point, after a break or tear, easy to stick up, but the resistance low temperature less than polyethylene film, low temperature embrittlement temperature -50 ℃, hardening temperature of -30 ℃, suitable for small wind sand dust, nighttime insulation requirements of high northern regions. Suitable for the cultivation of crops: cucumber, gourd, bitter gourd, etc. Polyethylene (PE) films of polyethylene (PE) films known as semi-double anti-drip films purposes: Shed, winter-type Greenhouse leaked film thickness: 7 wire -12 Esther: Yes extruded polyethylene resin blown film, semi-double anti-drip films have anti-fogging drip period of three months, because of its low cost, poor insulation, longevity films such materials generally should not be used on winter-type greenhouse, shed more for vegetables suitable for growing crops on: all vegetables grown in grout film applications Shed: The Shed, winter-type Greenhouse leaked film thickness: 7 -12 Esther wire: the grout film is based on the original films of polyethylene over conduct Again processed in PE film surface layer of paste filling, let's attached to the surface films, fog drip prolongation. Suitable for the cultivation of crops: Shed all the vegetables planted PO film applications: High arched type Greenhouse Thickness: 10-15 Esther sex: PO often refers to a polymer of ethylene, propylene or higher olefins. Wherein the ethylene (PE) and propylene (PP) is most important. PO film was recently adopted by the Japanese raw materials higher olefins and other additives, the use of external spray drying process and output of a new type of plastic sheeting. The advantage more prominent, and the market of traditional PE film EVA film comparative advantage prominent, but the high price, the advantage is mainly manifested in the following aspects: (1), excellent transparency: the use of raw materials, higher olefins, low haze high transparency. This morning, high light transmittance, low scattering, which would heat up quickly in the morning. (2), super sustained anti-fogging, dripping capability: the anti-fogging coating drying process flow drops, can inhibit the mist generation, anti-fogging drip period can be synchronized with plastic sheeting life. (3) strengthen the insulation performance: most of the internal organic insulating film with high-tech special agent, so shed outward infrared radiation is reflected back. Effective control of heat loss. To ensure that the growth temperature of the crop at night, shortening the maturity. Can effectively prevent the sudden drop in temperature at night cause frost damage to crops. (4) long life: the use of high-tech antioxidants and light stabilizers, greatly extending the service life of plastic sheeting, normal use can reach more than 3 years. (5), superior tensile strength. Materials with superior tensile strength and tear strength. (6), anti-static, dust-free: the use of nanotechnology, four-layer structure. Surface anti-static treatment. No precipitates, easy to absorb dust, to maintain long-term effects of high light transmission. (7), reduce pests and diseases, for organic vegetable production Sunshine makes shed plenty of light to temperature quickly, leaked early, relative humidity decreases, pest lighter. UV through, good bactericidal properties, can reduce the number of drugs for more than 30%. Very suitable for green vegetables. (8), increase production, early good light transmission properties listed, photosynthesis strong, high temperature, high output naturally. Can increase 10-25%. Crop growing fast, and can be listed 5-10 days earlier. (9), crop bright color, good taste, high quality UV transmittance ordinary film is low, moderate UV through golden sunlight, so the studio environment approximate field planting. Bright colored fruit crop cultivation, uniform, good taste, superior quality. Suitable for the cultivation of vegetables: for high-end multi-span greenhouse, can nursery, planting flowers and all kinds of vegetables PEP profits film Uses: High arched type Greenhouse Thickness: 10-15 Esther: the three co-extruded, that different Do not use a layer of different materials, and add different masterbatch, the film reflects the best functional composition, PEP profits film has good tensile strength, toughness, very good flexibility, light transmittance , heating up fast, very suitable for the local region of the northern winter cold and lack of sunshine, more clouds climate year round, PEP profits film also contains a high percentage of EVA and UV absorbers, can achieve good insulation effect, promote early crop harvest improve crop quality, saving agricultural sources suitable for the cultivation of vegetables: for high-end multi-span greenhouse, can nursery, planting flowers and all kinds of vegetable prices: 9 wire: 2.5 yuan / square meter Film: mulch can improve soil and near-surface temperature and water conditions, serve to improve soil temperature, soil moisture, soil improvement shape, improve soil nutrient supply situation and fertilizer use efficiency, improve lighting conditions, reducing the role of weed and pest hazards.
