Irises should be watered enough after planting, and then should be watered reasonably according to the growth of irises in the future to avoid water shortage and drought in the soil. If it is planted in September, then the sunshade net will be used for about half a month. In October, the shading material should be removed step by step, not at one time, to avoid blind flowers caused by drastic changes in light. We should pay attention to the proper covering cloth every night to improve the heat preservation capacity of the soil. Do a good job of ventilation during the day to prevent the temperature from exceeding 25 degrees.
Secondly, the car sunshade protects the vehicle instrument equipment. Direct sunlight will make the temperature in the car as high as 70 degrees, not only the shell of the center console is easily deformed, but also the instruments and audio equipment on the dashboard will be damaged by high temperature, such as aging parts, unsoldering pins and so on. Sunshades can effectively avoid direct sunlight.
Car owners who are more attentive to car maintenance usually open the car sunshade curtain after parking, which can be customized according to the car. It is mounted on the front windshield and is fixed by four large transparent suckers that can be washed and will not leave a mark on the glass. The unique corrugated design can refract most of the heat energy in the sun, infrared and ultraviolet rays, ensuring that the temperature of the center console will not rise a lot, and the temperature in the car is also much lower.
With the passage of time, EVA foam is widely used in electronic appliances, pearl cotton instruments, computers, audio, equipment, industrial control chassis, hardware lighting, handicrafts, glass, ceramics, home appliances, spraying, furniture, alcohol and resin and other high-grade fragile gifts, hardware products, toys, melons and fruits, leather shoes, daily necessities and other sold goods. In addition, EVA foam is characterized by excellent anti-infrared ultraviolet ability and is the primary sunshade product. It has a good anti-skid and shock absorption effect. It has many advantages, such as waterproof and moistureproof, shockproof, sound insulation, thermal insulation, good plasticity, strong toughness, recycling, environmental protection, strong crashworthiness and so on.
At the scene, there was an endless stream of citizens coming to buy tents, and the shop assistants were also busy introducing goods to customers. According to the shop assistant, “Outdoor tents include sunshade picnic tents and overnight tents for wind and rain protection, and the former sells relatively well.” With a fast-opening picnic tent of more than 300 yuan and a picnic mat of dozens of yuan, you can have a perfect picnic and enjoy a wonderful weekend. ”
Solutions: strengthen leek field management, control temperature and humidity, timely watering, pay attention to cooling and such work in summer, greenhouse planting can be cooled and protected from the sun by building a sunshade net. Pay attention to guard against cold snap in early spring and late autumn and reduce the occurrence of frost injury. Secondly, through the vents on both sides of the greenhouse to adjust the temperature in the greenhouse, it is best to control the temperature between 20 and 30 degrees. The greenhouse can be covered with grass to keep warm in winter.
At present, spray-free plastic has been successfully used in the automotive field of side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other auto parts. Bioplastics bioplastics are produced under the influence of microorganisms using original plants as raw materials, such as sugar cane, corn and so on. Most of the commonly used plastics are synthesized from petroleum products, and there are usually small molecular harmful substances that do not fully react, while bioplastics, due to the use of renewable raw materials with low toxicity and low harm, can significantly reduce the amount of VOCs volatilization in the car after being prepared into automobile interior parts. In addition, this bioplastic can be broken down to facilitate subsequent recycling, making it a more environmentally friendly plastic category.
The application environment of automobile interior fabric is special, and there are great differences in the performance requirements of interior fabric, such as high wear-resistant polyester fiber used in seat fabric to meet the needs of wear resistance; high light fastness and anti-ultraviolet fiber is used for sunshade curtain or instrument panel coating fabric, and high elasticity and high extensibility fiber is used for commercial vehicle roof with large Radian and door panel with large concave and convex curvature. Special vehicles such as operating buses and school buses have stringent requirements on the combustion performance of interior fabrics, and the main considerations are combustion rate, smoke density and limiting oxygen index; the fabric prepared with high flame retardant polyester fiber can meet the requirements of standards and regulations. In addition, the melt spinning of functional masterbatch and polyester chips prepared by nano-hybrid technology can develop high-performance polyester fibers with different additional functions, such as antibacterial functional fiber, negative ion functional fiber, water-poking fiber and so on.
