② car sunshade can reflect heat to achieve the purpose of cooling. Place a sunscreen at the front windshield to prevent direct sunlight from raising the temperature inside the car;

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.

When the police tried to contact the owner and the driver, one detail caught the attention of the experienced police in the special class: since the vehicle entered Shandong at 5 a.m. on November 5, the driver has been wearing a black mask and covering his face with a sunshade, apparently avoiding surveillance along the way.

However, the effect of indoor shading is not as good as external shading, it only blocks the light, but not the heat. When the light encounters the inner shading facilities, the radiant heat has already entered the room through the glass, and the glass temperature will rise very high. As for the external sunshade, only that part of the sunlight will reach the outer surface of the glass window directly. In general, bright indoor blinds can only block 17% of the solar radiation heat, while the outdoor horizontal sunshade with an elevation of 45 °south can block 68% of the solar radiation heat. The shading effect of the two is very different.

Yes. Unless the car is affixed with a darker glass explosion-proof film, it is difficult to recognize the condition inside the car near the car body in broad daylight, let alone a surveillance camera 2-3 meters high. However, according to the requirements of the “Technical conditions for the Safety of Motor vehicle Operation”, the windshield of the car and the laminated glass used by drivers to observe the line of sight can thus be seen that the transmittance should be higher than or equal to 70%, and all laminated glass cannot post reflective sunshade film.

As we all know, the main advantage of car shading is to block the sun, so that the light in the action area can not enter the car, to a certain extent, it can reduce the burning inside the car, and prevent leather seats and dashboards from being damaged by ultraviolet rays. But there are still some car owners who doubt whether sunshade really has the above effect.

The main function of the car sunshade is to reduce the temperature in the car and prevent the sun from reaching the objects in the car directly. Sunscreen is a combination of multi-layer bubble film and aluminum foil, which belongs to a kind of plastic products. Bubble film has good strength, toughness and impact resistance. Aluminum foil has the ability to reflect light, thus reducing thermal radiation and has low thermal radiation conductivity. 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. If you park for a short time, you can use a simple sunshade in the front windshield of the car, which is more durable and practical. The effect of shading is better.

At first, the improved locomotive did not have any front windows. After the EF58 electric locomotive was put into operation, the locomotive was modified according to the climatic environment along the line, such as installing an icicle cutting plate above the front window glass to prevent the running locomotive from hitting the icicles falling at the entrance of the tunnel and causing damage to the window. and add a cover to the whistle. In the later period, when the locomotive was transferred to the warmer climate area, the whistle cover of the locomotive was removed, but some locomotives only removed the icicle cutting plate and retained the whistle cover during car body maintenance. In addition, some EF58 electric locomotives in Hiroshima area are also equipped with front window windows, but the purpose is completely different from that of crossing the line, but it is used as a sunshade.

KXT single ball rubber joint is a kind of joint product connected by pipe or equipment, which mainly plays the role of shock and noise reduction of pipeline or equipment, protects the normal operation of Guomao of pipeline or equipment, and improves the service life of equipment or pipeline. The use or storage of KXT single ball rubber joints should avoid high temperature, ozone oil and acid-base environment. Sunny outdoor or windward pipes should be set up sunshade. Rainstorm, rain and wind turbidity are strictly prohibited. It is forbidden to brush paint or wrap thermal insulation materials on the surface of the joint.

So as to provide good indoor work when it is cold at night in winter, the closure of the sunshade can effectively prevent the loss of heat in the greenhouse and play the role of energy saving and heat preservation. According to the planting of crops. To ensure the reasonable function of sunlight, the name shading rate, energy saving rate, standard width, aluminum foil, inner shade, heat preservation type, aluminum foil inner shade, air permeable type, external shade, longevity, external shade, folding, folding,%% window system, gear and rack continuous window opening system is a window starting form often used in large multi-span greenhouse. The system runs smoothly, safely and reliably. In this system, the deceleration motor drives the gear to rotate through the drive shaft, the gear meshes the rack to make it move back and forth in a straight line, and the end of the rack is connected to the support of the ventilation window. So as to realize the opening and closing of the ventilation window. Choose the outer shading screen with different shading rates, which can make the sunlight diffuse in the greenhouse.
