The importance of glass greenhouse. Temperature is the basic condition to ensure the normal growth of crops. Greenhouse is a thermal insulation agricultural facility for the normal and rapid growth of crops. Heat preservation is an important work in greenhouse agricultural production, so suitable covering materials must be selected. Generally speaking, glass greenhouse is better than glass greenhouse, glass greenhouse can play a decorative role in appearance, and the aging and damage problems of glass greenhouse can be relatively small compared with plastic greenhouse; in terms of performance, due to the complexity of the environment, glass greenhouse can resist various loads (wind load, snow load, etc.). Aluminum alloy (or stainless steel) + plexiglass, ordinary glass, low-cost bamboo ponds and plastic films with beautiful and durable, windproof, rainproof, sunscreen, heat preservation effect and cost, can also be equipped with sunshade and sprinkler system. Plants usually need plenty of light and better glass. Of course, the one-time investment cost of plastics is lower, but the later maintenance cost is also higher, and plastics are easy to age.
Third, the exterior disposal of aluminum alloy sunshade panels for buildings: in the energy consumption of buildings, the consumption of resisting cold and heat accounts for a large proportion, and one of the main links to ensure the energy-saving performance of buildings is the enclosure structure of buildings.
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 Guangdong solar panel greenhouse needs the cooperation of a variety of equipment, with the increasing 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 how much the Guangdong sunboard greenhouse is, please contact Minghao greenhouse Engineering and Construction Company directly.
The cab. The flat head can be turned over, the torsion bar type overturning mechanism, the driver seat, the middle seat and the helper seat are arranged in the front row of the driving room. The driver seat can be adjusted back and forth, and the seat back angle can also be adjusted. There are berths in the back row with insulated carpets, sundries, quartz clock, cigarette lighter, receiver, sunshade, inner rearview mirror and curtain frame. Dongfeng single-bridge iron tank oil truck, the largest single-bridge oil truck has locks on both doors, the door glass can be lifted and lowered, and the triangular window and rear window can be opened. The front window is equipped with an electric wiper and washer, and the door is equipped with an external rearview mirror. There is instant wind, air conditioning optional.
Compared with the glass multi-span greenhouse, the cost of the glass multi-span greenhouse is lower, and the quality of the sunplate is lighter. The safety is higher; the thermal insulation effect of the sun board is better; the all-steel skeleton structure is sturdy and durable, and the service life is long, but the light transmission efficiency of the sun board decreases with the use time; the sun board needs to be replaced after serious aging; thermal insulation facilities are also needed in winter. Intelligent greenhouse is a kind of modern planting which integrates data acquisition, central calculation and automatic control of equipment. High-tech intelligent greenhouse is generally equipped with high automation facilities such as external sunshade system, internal masking system, internal heat preservation system, forced ventilation and cooling system of wet curtain fan, top ventilation system, heating system, power distribution / control system and so on. The managers input the data and control parameters needed for planting crops into the computer, and the intelligent greenhouse can realize unmanned automatic operation.
The sun board integrates daylighting, thermal insulation 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-scale lighting house, a sunshine, crystal transparent, warm and pleasant. In terms of greenhouse construction, there are greenhouses built with sunboards, gables and sidewalls using sunboards; as for greenhouses, there are production-oriented greenhouses, trade greenhouses dominated by flower trading centers, and greenhouses dominated by scientific research. Sunpanels are a widely used building material and can also be used in sunshades and canopies.
