Although the solar greenhouse has a very good thermal insulation performance, but from the point of view of safety, heating equipment is still an important factor. The southern part of our country generally does not need to heat up, but if we encounter bad weather continuously, we still need to use the energy stored in the greenhouse itself, otherwise it will not be able to meet the growth of vegetables. Therefore, whether in the south or north, heating equipment has always been a necessary protective measure. The technical aspect requires that in the equipment configuration of solar greenhouse, the configuration of thermal insulation equipment should be demonstrated in great detail. Of course, the work of Zhuzhou conjoined greenhouse requires the cooperation of a variety of equipment, with higher and higher temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied. For more information about the cost of Zhuzhou conjoined greenhouse, please contact Minghao greenhouse Engineering Construction Company directly.
After the rubber joint is subjected to pressure for the first time (such as installation and pressure test, etc.) or before it is reactivated after long-term shutdown, the bolt should be tightened again and put into operation. The effective expansion deformation of the bellows of the working main body is used to absorb the size changes caused by thermal expansion and cold shrinkage of pipelines, ducts and containers, or to compensate the axial, lateral and angular displacement of pipelines, ducts, containers, etc. The use or storage of Weihai integrated water processor should avoid high temperature, ozone, oil and acid-base environment. Sunshade racks should be built for pipes used outdoors or facing the sun and the wind, and exposure, rain and wind erosion are strictly prohibited. Paint and winding thermal insulation materials are strictly prohibited on the joint surface. Due to the aging problem of rubber products, it should be inspected and replaced in time. The benefits of this: first of all, the working pressure: the commonly used rubber joint pressure has the same size.
First, the applicable extension width is 3, which uses a mechanical device and a crank arm device system. Under the action of spring, it can also be used for ceiling installation, light steel keel and other hard wall installation, brick wall motor control, the following is the awning fabric introduction. 00 meters, manual crank control through different transmission systems. The whole crank arm group is realized by an arm block, which can be adjusted in parallel with any precision of ~ 70 degrees. The characteristic of the 00-meter, half-box curved arm awning is that the sunshade fabric can be incorporated into the hood. Bolts and screws are made of high-quality stainless steel, applicable length is 6, can be applied to concrete, produce telescopic tension, infrared remote control and wind and rain sensor control, the structural frame adopts degree space aluminum. Wood. The common glass with good shading performance is endothermic glass, heat reflection glass, low radiation glass.
3. The exterior ornaments of the car body mainly refer to decorative strips, wheel covers, signs and embossed words, etc., and accessories such as radiator masks, bumpers, lamps and rearview mirrors also have obvious decoration. 4. Car interior decorations include dashboards, ceilings, sidewalls, seats and other surface decorations, as well as curtains and carpets. Surface finishing materials such as natural fiber or synthetic fiber textiles, artificial leather or multilayer composite materials, skin foam and so on are widely used in cars. On the bus, there are a large number of decoration materials such as fibreboard, cardboard, engineering plastic board, aluminum board, pattern rubber board and composite decoration board. 5, body accessories door locks, door hinges, glass lifts, various seals, windscreen wipers, windwindow scrubber, sunshade, rearview mirror, handle, cigarette lighter and ash box, etc. Radio recorders and pole antennas are often installed in modern cars.
At present, spray-free plastic has been successfully used in the automotive field of side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other auto parts. Bioplastics bioplastics are produced under the influence of microorganisms using original plants as raw materials, such as sugar cane, corn and so on. Most of the commonly used plastics are synthesized from petroleum products, and there are usually small molecular harmful substances that do not fully react, while bioplastics, due to the use of renewable raw materials with low toxicity and low harm, can significantly reduce the amount of VOCs volatilization in the car after being prepared into automobile interior parts. In addition, this bioplastic can be broken down to facilitate subsequent recycling, making it a more environmentally friendly plastic category.
To reduce direct sunlight radiation from roofs, walls, windows and indoors through windows, eaves, sunshades (awnings), coated glass, etc., can be used to reduce the radiation heat of sunlight absorbed by external walls and roofs, and light-colored exterior wall finishes can be adopted. the insulation layer is set on the outside of the external wall and roof, or overhead roofing and other measures.
The interior part is composed of instrument panel and top cover lined with sunshade panel, door guard plate, etc., its function is to increase the aesthetics of the interior shape, improve comfort, and ensure the safety of passengers. The main functions of the dashboard are as follows: install all kinds of instrument variable speed joystick and other auxiliary parts. There is no danger of bulge and acute angle caused by impact, and it can effectively produce deformation and damage to protect the occupants.
