Do a good job in the production and supply of vegetables in winter and spring. Facility vegetable production should do a good job in facility repair and heat preservation, adopt measures such as multi-layer film mulching and adding thermal insulation quilts to strengthen facility heat preservation, and if possible, heating equipment can be used to increase temperature. completely eliminate the hidden dangers of production risks such as old facilities, heating charcoal and fire. Conscientiously implement measures such as clearing communication canals, timely uncovering and replenishing light, scientific fertilization and water pipe, etc., and make use of fine weather to restore ventilation and dehumidification in time after rain and snow, reduce the humidity of the shed, and reduce the occurrence of diseases. Vegetables in the open field should clear the ditch and manage the soil moisture in advance to prevent stagnant water in the field; if possible, cover materials such as plastic film, non-woven cloth or sunshade net should be directly covered with floating surface to prevent cold; mature vegetables should be harvested and listed in time to ensure that the main vegetable products are not out of stock and unbroken, so as to promote market price stability.
At present, spray-free plastics have been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts in the automotive field. Bioplastics bioplastics are produced by using original plants as raw materials, such as sugar cane and corn, under the action of microorganisms. Commonly used plastics generally use petroleum products, and there are often small molecular harmful substances that do not fully react, while bioplastics, due to the use of low-toxic and low-harm renewable raw materials, greatly reduce the VOCs volatilization in the car after turning it into automobile interior parts. In addition, this bioplastic can be used for subsequent use, and is a more environmentally friendly type of plastic.
Sunshade cosmetic mirrors are already common in models at this price, but the lighting function is intimate. The floor accelerator pedal is also different from the conventional model, which helps the driver to control the vehicle more accurately. Although external audio is popular nowadays, Mazda 3 Onksera not only supports MP3 and WMA playback, but also provides a single disc CD function, which can be called a “welfare” for nostalgic consumers. The control panel behind the block is used to set all the information in the central control screen, and the functions such as multimedia, navigation and system favorites are designed with independent buttons, which is worthy of recognition.
The total amount of energy consumption of a building is mainly affected by various energy-using equipment inside the building and the external enclosure structure that constitutes the building. Due to the vigorous implementation of building energy conservation in China in recent years, the construction technology of building energy equipment and external enclosure structure has undergone profound changes. For example, the roof in the building enclosure structure has evolved into a roof with thermal insulation effect. The external walls also increase the performance of thermal insulation, while curtain walls, doors and windows not only have the performance of thermal insulation, but also installed a sunshade system. This series of energy-saving measures not only improve the working efficiency of the equipment, but also explore and develop some new energy or renewable energy, so the building construction technology needs to be developed and improved synchronously. The author briefly describes the new materials and technologies of building energy saving, as well as their application in construction.

Automobile manufacturing industry has always been an important consumer market for polyurethane products. The interior decoration of foamed polyurethane plastic for bridge car includes seat cushion, headrest, sound insulation, dashboard, sunshade, door panel, roof lining and so on. Car polyurethane purchased parts include bumper, flow stopper, front and rear ribbon, grille, rear side plate, door panel, fender and so on. The application of polyurethane in automobile is expanding day by day because of its good plasticity and strong application of material properties.
