Shanghai Luotaofu PC sunlight board integrates daylighting, heat preservation and sound insulation, which can be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. Foreign countries even appeared in addition to the supporting structure, pure polycarbonate material of large transparent lighting house, a sunshine, crystal transparent, warm and pleasant. In the aspect of greenhouse construction, there are greenhouses built with sun panels, greenhouse with gables using sun panels, and greenhouses built with gables and sidewalls using sun panels. In terms of greenhouse efficacy, there are production-oriented greenhouses, trade greenhouses based on flower trading centers, and greenhouses based on scientific research. Sunpanels are a wide range of building materials that can also be used in sunshades and canopies. Zhejiang general-purpose solar panel

As a new type of packaging material, plastic has been widely used in the field of packaging. For example, all kinds of hollow containers, injection molding containers, packaging films, woven bags, styrofoam straps, packing straps, etc. In terms of transport, the plastic used in vehicles, trains, ships and other means of transport and corresponding ancillary facilities is increasing year by year on a per-vehicle or per-vessel basis. Varieties include fuel tank bumper, sunshade seat, door handle, steering wheel, dashboard and so on The commonly used materials in agriculture are film, pipe, plate, rope, woven bag and so on. Plastic granule manufacturers introduce the packaging for plastic greenhouse, crop fertilizer and so on, plastic pipes for farmland and water conservancy projects, farmhouse construction, animal husbandry protection, agricultural machinery and utensils, fishing net culture, floating, etc.
Car interior parts mainly include: steering wheel, car partition, door inner panel, dashboard, airbag cover, seat armrest, carpet cushion, door handle, cup holder, decorative strip, ceiling, sunshade, side window frost protector, miscellaneous box and cover, sound absorption and other parts. The materials used play a key role in the lightweight, economy and comfort of interior parts, in which plastic has become the mainstream of interior materials, accounting for more than 80%.
In summer, the indoor air conditioning load mainly comes from the solar radiation heat of the windows entering the room, so taking effective shading measures is an effective way to reduce solar radiation. The calculation of sunshade is very important in the calculation of load and energy saving of air-conditioned buildings. Building shading methods can be divided into three categories: external shading, characteristic glass and internal shading. External shading can be constructed by sexual building shading, such as sunshade panels, sunshade panels, eaves, etc., or it can be movable and adjustable, such as louvers, movable baffles, rolling curtains and so on. These sunshade structures are commonly used in traditional buildings. Characteristic glass is the use of modern glass coating technology, so that the window glass can choose the incident sunlight, play as much as possible to introduce visible light, while reducing infrared light into the room.
For this reason, the competent departments of agriculture and forestry in many places have issued various measures to require farmers to do a good job in the prevention and remediation of crops in order to deal with the “late spring cold.” For example, for the vegetable greenhouse, the relevant departments stipulate that “when the temperature in the greenhouse is below 0 ℃ for a long time, straw bags, non-woven cloth, sunshade net and other mulch should be added in the greenhouse at night to prevent frost injury and take basin fire or fire temporary heating. At the same time, open fire can not be used when heating to prevent smoke damage, it is necessary to set up a flue to discharge harmful gases outdoors. Strengthen the coverage in time to promote heat preservation and anti-freezing. ”
Seinfeld sun umbrellas are put away like ordinary umbrellas. The car sunshade is designed according to the shape of the car through the sun protection principle of the sun umbrella, covering from the front windshield to the rear windshield, which can effectively reduce the temperature in the car at high temperature.
Car sunshade: made of multi-layer bubble film and aluminum foil. Aluminum foil effectively reflects light, thus reducing thermal radiation and blocking heat conduction. At the same time, ultraviolet rays are also reflected by aluminum foil, reducing the damage caused by ultraviolet rays to leather seats and dashboards.
