Of course, the cooling work of the greenhouse in summer can not rely entirely on the greenhouse insulation quilt, but also should take some other measures accordingly. Can cooperate with enhanced ventilation to cool down, but it should be noted that it is best to set up a wind shield in the tuyere to avoid the cold wind blowing directly on vegetable and fruit noodles; you can also use a sunshade net to cool down, and the shading rate of the shading net can be selected according to your needs. The advantage of shading net is that it can not only prevent sunburn vegetables, but also allow part of the light to illuminate the interior of the greenhouse, ensuring the photosynthesis of vegetable leaves; you can also take spray cooling methods.

In the internal thermal insulation system, when the greenhouse or indoor temperature drops to the set low temperature limit at night, the thermal insulation quilt is turned off, the heat preservation of the greenhouse is strengthened, the ground radiation heat loss is reduced, the heating energy consumption is reduced, and the operating cost of the greenhouse is greatly reduced; the shade curtain can be opened during the day to make the greenhouse fully daylighting. The working principle is the same as that of internal sunshade, which is made of a lightweight quilt that does not absorb water and weighs between 100 and 150 grams.

This kind of agricultural film usually results in poor light conditions in the greenhouse, and the temperature is relatively low and the humidity is relatively high, which aggravates the diseases and insect pests to some extent. The heat preservation performance of agricultural film is poor, especially the noon temperature in summer and autumn is easy to be too high, so it is necessary to do a good job of cooling: suitable for feeding wet leaves. It is easy to cause mulberry leaf withering after high temperature and ventilation in the shed. Wet leaves can be fed at noon on a sunny day and air spray with effective chlorine concentration bleaching solution is used to replenish moisture and prevent disease. Increase ventilation. After sunrise on a sunny day, open the film on both sides of the greenhouse for ventilation, and put down the film on both sides to keep warm when the temperature in the shed drops below the suitable temperature for feeding in the evening. When the temperature is high, ventilate day and night. Put down the sunshade net on both sides of the greenhouse on rainy days and lift the film on both sides of the greenhouse to facilitate ventilation.

Sunglasses are a good sunshade artifact for early summer, and the style with full personality coincides with black in style. Sunglasses, t-shirts and bags all use black as the same color, which makes the shape highly consistent in color. The atmosphere of round collar with pleated skirt is very suitable for mature women, and the loose design of skirt pendulum adds detailed pleated small elements to become more detailed.

Zhaoyuan in the building to meet the design requirements of the premise, the addition of external sunshade, awning and appropriate increase in the length of the southward balcony can play a certain sunshade effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which has a decorative effect on the front, forming a less mobile space layer about 50mm thick between the glass and the curtains. In this way, a good effect of thermal reflection and thermal insulation can be achieved, but the direct lighting is poor and should be made into a movable type. In addition, installing blinds with certain thermal reflection on the inside of the window can also obtain a certain thermal insulation effect.

Greenhouse management: first, we should do a good job of anti-freezing. Freezable flowers can be equipped with an inner film in the greenhouse to form a two-layer film for heat preservation, and heating can also be carried out in the greenhouse if possible. Second, it is necessary to do a good job in strengthening the greenhouse. On snowy days, when there is snow in the greenhouse, we should remove the snow from the roof in time, increase the light transmission, prevent the greenhouse from being crushed by the snow, and reduce the freezing low temperature after the snow melts. When clearing the snow, you should avoid piercing the greenhouse film and transport the snow out of the nursery. The greenhouse with collapse and collapse deformation should be strengthened and repaired immediately, and if it cannot be repaired, the plants in the shed should be transferred in time, or covered with film, grass curtain or sunshade net to improve the heat preservation effect.

In terms of transport, the plastic used by vehicles, trains, ships and other means of transport and corresponding ancillary facilities is increasing year by year on a per-vehicle basis or per-vessel basis. Varieties include fuel tank, bumper, sunshade seat, door handle, steering wheel, dashboard and so on. As a new type of packaging material, plastic has been widely used in the field of packaging. For example, a variety of hollow containers, injection containers (turnover boxes, containers, buckets, etc.). Packaging film, woven bags, styrofoam, binding rope and packing straps, etc.

First of all, what we have to consider is the orientation of the balcony. If the balcony at home is sunny, and the light is particularly good, then it is recommended to install a sunshade, so that when the sun is very strong or weekend rest, you can use sunshade to block the heat. The overall beauty and neatness, which can highlight the elegance and formal sense of modern architecture, has become a popular choice for sunshade inside many modern buildings. Sunshade electric canopy curtain outside the sun room is generally divided into two categories, one is folding electric canopy curtain, the other is reel electric canopy curtain. The main feature of the folding ceiling curtain is that it is wavy when it is opened and folded together when it is folded. Each pair of ceiling curtain is composed of left and right guide rails, which drive the track when the motor starts, and the fabric is drawn by an elastic guide shaft in the middle to achieve the purpose of sunshade.
