In addition to its light weight, due to the higher heat resistance of EPP automotive pillows, polypropylene foam is more advantageous than polyethylene foam and polystyrene foam in areas where higher operating temperatures are required, such as sunshades, instrument insulation panels and areas where the temperature between the doors is easy to rise. However, in addition to the field of energy absorption and heat resistance, polypropylene foam also has good thermal weldability, which makes polypropylene foam is also widely used in car sheds, doors, car roofs, carpet support materials, sound insulation panels, door linings and luggage racks, etc., and its good thermal processing type makes it widely used in control boxes, shock-proof panels and other components. In addition, polypropylene foam can also make steering wheel, door inner panel energy absorption protection pad, buffer pad, headrest, toolbox, cushion, dashboard and so on.
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.
The interior design of the vehicle has changed from the previous generation family design of the old Mercedes-Benz GLE, using an integral sunshade to integrate the dashboard and the liquid crystal display on the central console. The dimensions of both LCD monitors are 12.3in. In addition, users can also choose to install HUD head-up displays. Under the concept of vitrified cockpit, the function of the center console has been completely weakened. Compared with the new generation of Mercedes-Benz E-class design, the new generation of Mercedes-Benz GLE integral sunshade design will feel better, and as the central air outlet between the upper and lower parts of the dashboard, it also uses four rectangular structures. After the elevation of the height and width of the sub-dashboard, the encapsulation has also been fully strengthened.
Polyurethane foam is widely used in automobile interior decoration and parts that absorb vibration. Its main products are: dashboard, rearview mirror frame, bumper, seat cushion, headrest, steering wheel, control box, instrument board anti-vibration pad, front and rear pillar decoration, middle pillar decoration, front top lining, window frame, ceiling and side roof frame decoration, door liner, sunshade panel, rear roof frame decoration and so on.
According to the management of medium-and long-term weather forecast, in case of continuous low temperature, the temperature of the mushroom house / shed should be kept above 8 °C ~ 10 °C. The main measures for heat preservation and warming include: thickening the roof cover at night; hanging blankets on doors; closing doors and windows for heat preservation in the morning and evening; opening doors and windows around noon in sunny days; opening only leeward vents for short-term ventilation in rainy and snowy weather; in cold or windy weather, close doors, windows and vents to prevent cold air from attacking. When the weather is fine, open the cover to increase the temperature of the light, when the light is strong, it is best to set up a sunshade net under the greenhouse film and above the bacterial stick to protect the light and heat. If there are heating facilities such as hot air stove, the temperature of the mushroom room / shed can be increased by heating, but attention should be paid to prevent the smoke from being discharged into the shed and cause poisoning. In addition, the ditch cleaning and drainage of the mushroom shed should also be done to reduce the humidity in the greenhouse in the rainy season and improve the mushroom quality.
Three major cooling measures for greenhouse. If winter is over, can summer be far behind? With the increase of summer temperature, how to cool the greenhouse properly has become an important work of daily management. Below, the editor of Tengchong greenhouse will introduce the following six cooling measures. First, external sunshade system. In order to minimize heating costs and improve efficiency, how to enhance the heat preservation capacity of Baoshan greenhouse and reduce heat loss has become a concern of many greenhouse users. Is to cover the excess sunlight outside the greenhouse to form a shade to protect the crops in the greenhouse, so that the temperature in the greenhouse is kept at a suitable temperature. This can effectively block direct sunlight crops without affecting the natural ventilation in the greenhouse, and the cooling effect is better than that of internal shading, but external shading materials are required to be sturdy, durable, flexible and anti-aging
Now the weather is getting hotter and hotter, many people would rather stay at home and not go out, and for some people who drive to work, it is really a very painful thing. Every time the car door is opened, it is like a sauna. So when car owners park, they will choose to take the sunshade out to block the sun to avoid the excessive temperature in the car, so is the sunshade really useful? Come and have a look with the editor.
