SVETLITSAtmhothouseserves for 7 and more years without taking off for the winter.
The film is resistant to wind loads ("sailing" effect), is not afraid of hurricane wind (18 m / sec), strong hail, severe and snowy winters (frost resistance -80 ° C), sharp temperature drops. Even in cold weather, the film retains its elasticity, the snow can be shaken off from the greenhouse without fear of tearing the film.
Surface SVETLITSYtm hydrophilic (contact angle 45-55º instead of 70-84º for LDPE) due to the presence of polar components. The drops of condensate are flat and small, flowing down the walls of the greenhouse.
The illumination in the greenhouse is 20% higher than under the polyethylene film due to the high transparency of the film. The transmittance in the area of physiologically active radiation is up to 92%. Spectral characteristics are optimal for growing both seedlings and vegetables, as well as fruits, flowers and seedlings. During operation, the film is less dusty than polyethylene.
The film has an excellent heat-retaining effect, the transmittance in the area of thermal radiation is up to 12 - 28%.
In overlapping places, the film sticks together in a short time, blocking the access of cold air to the greenhouse. The greenhouse turns out to be very tight. If desired, the overlaps of the film can be easily separated when removing it for the winter.The temperature in the greenhouse is 2-4 ° C higher than under the polyethylene cover.
For areas with hot climates, films have been developed that protect plants from overheating and have different spectral permeabilities in the ultraviolet, visible and infrared regions. (reflective, light scattering, etc.). The transmittance in the region of hard ultraviolet radiation can be from 0 to 88%.
 | Normal 0 false false false RU X-NONE X-NONE MicrosoftInternetExplorer4 Mulching film servesat least 5 years without wintering. It is opaque, very elastic, tightly adhering to the soil, destroys old and prevents new weeds from growing. The root system of plants under the film develops better, it suffers less frost even in snowless winters, and the moisture under the film stays longer. The film improves the temperature regime of the soil, retains moisture in the soil, creates a greenhouse effect under the film and promotes intensive development of the root system. And, most importantly, it provides savings in manual labor for weeding weeds. Films are made in various colors to achieve maximum effect when mulching agricultural crops in open and closed ground. |
Film for the device of reservoirs, life time at least 10 years without removing for the winter.
Thanks to its unique combination of strength, elasticity, puncture resistance, frost resistance, the film is durable and ideal for the construction of reservoirs. It fits easily on the terrain and, if desired, can be removed for the winter. Not destroyed by plant roots. The film weld perfectly, the weld seam is very strong. There is a transparent film with an ice-blue tint, through which the natural soil of the reservoir is clearly visible, and the water looks unusually fresh. Plants and variegated inhabitants of the reservoir look great against the ice-blue background. Temporary shelters, gazebos, awnings, storage rooms are made of this transparent film. Black opaque foil can also be used if desired.
Waterproofing films... Film geomembranes, service life up to 50 years.
Films with a range of properties already listed are used in the manufacture of waterproofing of building structures, basements, wells, for the construction of sedimentation tanks, sludge collectors, silo pits, for the construction of shelters, warehouses, sheds, etc.
The main advantage of these films, in contrast to polyethylene films, is to maintain integrity under loads created by sharp, piercing objects - corners, sharp edges of stones, hardened concrete, ends of reinforcement bars, uneven ground, etc.
Photodestructible film Svetlitsa tm, life time from 1 to 4months.
After the required service life, under the influence of sunlight, the film breaks down into small fragments and is assimilated by soil microorganisms, which excludes soil contamination with the film.
Used by for grafting and budding fruit and ornamental trees. Due to its high elasticity, the film, reliably connecting the grafting sites, excludes the access of pests and pathogenic bacteria. It does not cut into plant tissue during growth and does not delay sap flow, which means that the trees do not get sick and develop well. After the site of inoculation has healed, the film is destroyed, which eliminates the time-consuming operation to remove it. In addition, it is used byfor mulching vineyards, vegetables and fruit and berry crops.
