Temporary shading is the installation of lightweight curtains, plastic blinds or pendants at the window, while sexual shading is the installation of sunshades in various forms at the window. The facilities of sexual sunshade system can be divided into active form and fixed form according to whether the components can be disassembled and moved. In recent years, the active sunshade system is widely used in buildings in our country, and the angle of the sunshade can be adjusted freely according to the annual seasonal change or the all-day sunshine change. Because of the strong flexibility of this facility, it can also be easily removed in order to get sunshine and avoid blocking the sun in the cold season. Today, with the rapid development of science and technology, there are all kinds of heat reflection glass, such as sunlight control film, coated glass, low emissivity film glass and so on.
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.
The optimum temperature for strawberry seedling growth was 25 ℃ ~ 30 ℃, and the stolon stopped growing when it exceeded 32 ℃. Therefore, in the early stage, the greenhouse should do a good job of heat preservation, improve the air temperature and substrate temperature, and promote the early emergence of stolons. In the southern region, the temperature from mid-May to early July is suitable for the occurrence of stolons, during which the number of stolons is large and the interval between stolons is short. From mid-July to August, with high light intensity and high temperature, the greenhouse should be covered with a sunshade net with a shading rate of 60% from 9 am to 5 pm every day, so as to reduce the temperature and ensure the normal growth of mother and offspring. In addition, moderate shading in the later stage of seedling cultivation can meet the low temperature and short day conditions needed for strawberry flower bud differentiation and promote strawberry flower bud differentiation.
To make a simple list, the Tianyi co-creation version has the following configurations: yacht electronic shift lever + steering wheel shift dial, electric tail door with foot induction opening and closing, 360-degree panoramic parking image, standard four-probe reversing radar, 12.3-inch full liquid crystal color digital dashboard, integral panoramic skylight (with electric sunshade), rain sensor intelligent front wiper.
Spray-free plastics are more and more used in home appliances and automobiles because of their excellent appearance, environmental protection and economy. In the field of household appliances, non-spraying materials are used in soymilk machines, drinking fountains, electric cookers, water heaters, washing machines, refrigerators, air conditioners, televisions and so on. In the automotive field, spray-free materials can be used for DVD face frames, central control panels, side skirts, glove boxes, sunshades, instrument panels, etc.
In a good greenhouse, it also requires careful daily maintenance. It takes longer to use it. The covering material of the multi-span greenhouse is generally sunny board or glass, and the thermal insulation performance is also very good, but the interior of the multi-span greenhouse is also equipped with heat preservation measures, which is called internal heat preservation in the industry, which is a very thin waterproof quilt. It is different from the heavy quilt in the solar greenhouse. The multi-span greenhouse thermal insulation is installed at the top and around the indoor, and the multi-span greenhouse adopts the form of internal thermal insulation. The configuration of the multi-span greenhouse belongs to the greenhouse industry, and both external sunshade and internal thermal insulation are configured. Places like the northeast have to be equipped with internal thermal insulation. But it is not called thermal insulation, the thermal insulation of the traditional solar greenhouse is covered outside the greenhouse, but the thermal insulation of our multi-span greenhouse is inside the multi-span greenhouse, and the general installation location is at the top.
The car is equipped with four-way adjustable main and auxiliary seat, which is wrapped in leather and fabric splicing material. At the same time, the rear seat can be put down by 5 stroke 5. In addition, the new car is also equipped with knob electronic block, air conditioning, main driving sunshade cosmetic mirror and inner rearview mirror driving recorder interface.
c. Functional class. Including car body insulation materials, anti-collision fillers, dashboards, sundries, indoor shelf panels or rear windowsill panels, sunshade panels, wheel cover covers, engine cover covers, etc.
Some car owners park their cars outside in the wind and rain. The front gear, rear gear and windows on both sides of the car are made of glass. The summer sun shines into the car through the glass, which will soon raise the temperature inside the car. Then we can give our car “sunscreen”, that is, we can use car sunshade to block the sun in all directions, so that the light can not enter the car, which can reduce the temperature in the car to a certain extent. it can also prevent leather seats and dashboards from being damaged by ultraviolet rays. Second, driving is not afraid of hot
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. ”
