Near Xiaoshan Volkswagen lossless car audio modification, because the car audio is mostly installed in the upper part of the dashboard, in order to avoid sunlight, 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. The specific heat of the circuit board and plastic components in the car audio mainframe is different, so it is affected by the temperature change to a different extent. In the scorching sun, it is good to use the sunshade to resist the scorching sun and avoid the direct sunlight.

The first choice to block the sun, of course, is the sunshade, but it has a certain impact on the line of sight. The second is to propose explosion-proof film and solar film. The most practical thing is to buy a polarizer for the driver. But with polarizer to remember one, suddenly enter the tunnel or parking lot and other dark areas should pay attention to safety.

The sun board integrates daylighting, thermal insulation and sound insulation, which can be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. Foreign countries even appeared in addition to the supporting structure, pure polycarbonate material of large-scale lighting house, a sunshine, crystal transparent, warm and pleasant. In terms of greenhouse construction, there are greenhouses built with sunboards, gables and sidewalls using sunboards; as for greenhouses, there are production-oriented greenhouses, trade greenhouses dominated by flower trading centers, and greenhouses dominated by scientific research. Sunpanels are a widely used building material and can also be used in sunshades and canopies.

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 temperature has suddenly soared in the past two days. I went out at noon like teppanyaki, standing in the sun for half an hour, and the sunshade hat was so hot that I dared not touch it directly with my hands. I think many parents in many parenting groups have begun to stock up on summer artifacts, holding small fans, cool towels and other gadgets to help in the group, which is very annoying. I am not interested in these at all. It is not suitable for children to use these. They are easy to catch cold.

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 Xuzhou greenhouse quilt 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 quilt quotation in Xuzhou greenhouse, please contact Minghao greenhouse Engineering Construction Company directly.

China stipulated on October 1, 2007, “the visible light transmittance of the front windshield is not allowed to be less than 70%, and the side window glass is not allowed to post mirror reflective sunshade film.” But in real life, there are often many car owners in order to save money, choose to paste a cheap high imitation film in the automobile supplies wholesale market or roadside shop, but do not realize that this kind of inferior film, not only can not work, but also because it contains formaldehyde, benzene and other harmful ingredients to release harmful substances to the car, damage to the health of passengers, less than two years will fade, but also need secondary film, secondary consumption of
