However, because the bubble body is a poor conductor of heat, the cooling process often shows that the surface bubble body has been cooled and solidified, while the temperature of the core bubble body is still very high, assuming that the cooling setting ends at this time, although the bubble body has been solidified and shaped on the outside, but the core is still at a high temperature, and its heat will continue to transfer, raising the temperature on the surface of the bubble body. Coupled with the expansion force of the core bubble, it is possible to deform or split the stereotyped bubble. Therefore, for EPP manufacturers, it is necessary to ensure a sufficient cooling setting time for the cooling and curing of foamed products. In areas where higher working temperature is needed, EPP foaming material is more advantageous than PE foaming material, such as sunshade panels, insulation panels of instruments and places where the temperature between the doors is easy to rise.
From the analysis of the environmental factors closely related to plant growth in greenhouse project, different temperature and humidity will have a direct impact on plant growth. Therefore, how to meet the requirements of different crop growth environment has become the main way to improve the production potential of greenhouse and realize factory planting. The intelligent greenhouse control system can not only monitor the internal environmental data of the greenhouse, set the upper and lower values of various environmental indicators, and remind managers of the abnormal situation of the greenhouse environment, but also work together by controlling the external sunshade, internal shading, internal thermal insulation, top natural ventilation system, fan water curtain forced cooling system, heating system and so on, so as to make the internal environment of the greenhouse within the scope of our design.
In order to avoid sunlight, car audio is mostly installed on the upper part of the dashboard; if the sealing strip of doors and windows is not strict, it should be replaced, otherwise the loudspeakers are easy to rust and damage, or even cause short circuit to burn out the mainframe; the circuit boards and plastic components in the audio mainframe, the degree of aging caused by temperature changes is not the same. In the scorching sun, it is best to use sunshades to ward off the scorching sun and avoid direct sunlight.

The car key door can be pulled out in two different gears, one of which is powered by a CD player. I just got it and changed a battery when I ran out of power. When I first got it, there was a noise in the back of the rear seat, the right rearview mirror was loose, the electric adjustment of the rearview mirror failed, the speedometer did not work (the fault was cured after changing the battery), the CD machine did not read the disc smoothly, and the front fog light was not lit. The rearview mirror reading lights and sunshade make-up mirror lights are not lit (the front car owner did not connect the line when the roof was packed), the rising window of the right front window was slow, and the valve chamber cover and steering power tubing leaked oil.
