Why use sunshade? The main advantage of car shading is to block the sun, so that the light in the action area can not enter the car, which can reduce the burning inside the car to a certain extent, and prevent leather seats and dashboards from being damaged by ultraviolet rays.

Now most cars are equipped with CD equipment, the main factors that affect the normal work of car audio in autumn are high temperature and humidity. Because the car stereo is mostly installed in the upper part of the dashboard, in order to avoid the exposure of sunlight (check transaction price | matching | preferential policy), the effect of using sunshade is better. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine.

PA has good impact resistance and strength. In the car body, it is mainly used to manufacture wheel front and rear cover, handle, door lock, seat belt fixing hinge, dashboard, fender, sunshade clamp, swing arm of seat back, gear, etc., in which the PA consumption of wheel cover is about 2kg/, which is a big market of nylon. However, when nylon is used as a large component, because the water absorption will cause size change or strength reduction, it can not fully maintain the performance of the parts, so it is necessary to modify PA.

Avoid direct sunlight and high temperature in the car. Dashboards, which control these areas, are mostly made of engineering plastics. plastics will age and fade after being exposed to the sun for a long time. Although we will do strict aging tests during development, it is good to pay more attention to them. So it is necessary to always have a sunshade mat.

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.

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.

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.

In terms of temperature management, the early growth stage of spring cauliflower cultivation was in the low temperature season, and the growth was small, while the plant size of broccoli was closely related to the flower head yield, and the temperature increased rapidly in the later growth stage, which was disadvantageous to the flower bud differentiation and flower ball formation of broccoli. Therefore, in the field management, it is required to do a good job of heat preservation in the early stage of growth to prevent freezing. Those cultivated in greenhouse should be closed in time to keep warm, those cultivated in open field should be trenched and drained as soon as possible to prevent freezing, and the remedial method of covering the floating surface of sunshade net should be adopted in case of sudden frost or freezing weather. In the later stage of growth, after the temperature rises in April, the protected cultivation should do a good job of ventilation and cooling in time, and the flower heads should be harvested in time after maturity.
