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 greenhouse film in Gansu needs 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 greenhouse film in Gansu, please contact Minghao greenhouse Engineering Construction Company directly.
The internal thermal insulation system can be divided into the top and the side, and the principle is to reduce the heat loss in the shed by arranging automatically contractible thermal insulation curtains on the top and side parts, so as to achieve the effect of thermal insulation. At the same time, after the expansion of the internal thermal insulation system, the moisture in the shed is isolated so as to reduce the role of condensed water on the roof. Like the sunshade system, the top internal thermal insulation system is closed by aluminum alloy moving edge, deceleration motor, transmission rack and hot-dip galvanized push-pull rod.

The car sunshade curtain can prevent the light from entering the car, reduce the heat inside the car to a certain extent, and prevent leather seats and dashboards from being damaged by ultraviolet rays.
Chinese automobile media reporters have tested the special sunshade film affixed to the car window, and the conclusion shows that it does have a certain sunshade and heat insulation effect. However, this kind of sunshade film will seriously reduce the light transmittance, resulting in poor vision at night, so it is not recommended to install the sunshade film on the windshield. Other side windows can be mounted with sunshade film if necessary, although the shading effect is not necessarily obvious, at least it can better protect the privacy of passengers.
The heat preservation work in the greenhouse can be accomplished by using side insulation and top inner insulation curtain (figure 4), as well as internal and external sunshade curtain and top skylight. The heat preservation work can be carried out 2 hours before sunset. Close the top skylight 2 hours before sunset, expand the internal heat preservation, and then gradually expand the internal sunshade and side insulation. All the internal heat preservation, inner sunshade and side heat preservation will be carried out before sunset. If necessary, external shading can also be fully carried out for thermal insulation. When the external solar radiation is less than 300W/m2 (blade stomata closed) and need heat preservation, you can directly turn on internal heat preservation, side heat preservation and internal shading, and close the top skylight at the same time.
At present, spray-free materials have been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts in the automotive field.

When the sun shines on the sunshade, some of the heat will be blocked, and the ultraviolet light will be reflected by the aluminum foil. Car sunshade can prevent leather seats and dashboards from being damaged by ultraviolet rays. Direct exposure to the sun will make the temperature in the car as high as 70 degrees. Not only the shell of the central console is easy to deform, instruments and other equipment on the dashboard are also damaged by high temperature, such as aging components, pin soldering, etc., sunshade can effectively avoid direct sunlight.
11. After the concrete has been poured, covering or spray curing should be carried out immediately before the initial setting. Concrete thermal insulation materials can be made of plastic film, geotextiles, gunny bags, flame retardant quilts and so on. If necessary, wind shielding shed or sunshade greenhouse can be set up. In the thermal insulation maintenance, the temperature difference and cooling rate of the concrete pouring body should be monitored on the spot, and when the measured results do not meet the requirements of the temperature control index, the thermal insulation maintenance measures should be adjusted in time.
