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.
◆ 2 is to protect against cold and keep warm. Pay attention to the heat preservation of vegetables, check whether the greenhouse film is broken or not, close the shed timely in the morning and evening, properly uncover the film and ventilation when the temperature is high, adjust the temperature and humidity in the greenhouse, and increase the light. After the air temperature drops below 5 ℃, we should take multi-layer covering and heat preservation, and if necessary, take measures such as electric heating, emergency lighting, etc., especially to do a good job in the heat preservation of vegetable seedling places. Open-field vegetables can be tied around the waist, floating surface covering sunshade net, straw and other anti-freezing.
For this reason, the competent departments of agriculture and forestry in many places have issued various measures to require farmers to do a good job in the prevention and remediation of crops in order to deal with the “late spring cold.” For example, for the vegetable greenhouse, the relevant departments stipulate that “when the temperature in the greenhouse is below 0 ℃ for a long time, straw bags, non-woven cloth, sunshade net and other mulch should be added in the greenhouse at night to prevent frost injury and take basin fire or fire temporary heating. At the same time, open fire can not be used when heating to prevent smoke damage, it is necessary to set up a flue to discharge harmful gases outdoors. Strengthen the coverage in time to promote heat preservation and anti-freezing. ”
Two days ago, Sun Li also posted a photo of Duomei modeling another handbag made by her mother. In the photo, Duomei is wearing sunglasses and a sunshade hat, wearing a white shirt skirt and carrying a handbag made by her mother. She is dressed in a fresh and fashionable literary style.
As a hot automotive supplies, the material of the sunshade is composed of seven layers of materials, wear-resistant and heat-proof, anti-ultraviolet up to 99%, and the optimized material thermal insulation is also increased by 99%. It is found that the heat insulation of the optimized material can be directly reduced by 20 degrees before and after use. such a powerful ability is undoubtedly an indispensable good thing for cars.
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.
The construction of greenhouse mainly adopts frame structure, which has high bearing capacity and long service life, and generally has the functions of heat preservation, ventilation, sunshade, insect prevention and so on. The span of the greenhouse is generally 7 ~ 9 meters, the shoulder height is 3 ~ 4 meters, and the top height is 5 ~ 6 meters. Because of the high structural strength, it can be built either as a single building or as a multi-building. The structure of the ordinary greenhouse is relatively simple, and the installation can be carried out according to the operating instructions. Before planting in the greenhouse, we need to do a series of work, such as the construction of the greenhouse, the consideration of the planting time of vegetables, the purchase of vegetable seeds in the greenhouse, and so on. In fact, if we want to make the income of planting in the greenhouse better, we also need to do some meticulous work on the fertility, diseases, pests and other factors in the field.
Such as: speakers, dashboards, folders, lamps, vacuum cleaners, filters, electric mosquito rackets and so on. The application range of double-head ultrasonic plastic welding machine: used in car body, door, lights, car reversing mirror, sunshade, interior parts, filter, bumper, cable, oil cup, water tank, fuel tank, air duct, exhaust gas purifier, tray filter plate and other automotive products plastic parts. Plastic electronic products for double-head ultrasonic plastic welding machine: prepaid water meter, communication equipment, cordless telephone, mobile phone accessories.
Most of the car is made of delicate leather, metal and wood, needless to say the degree of meticulous workmanship. The dashboard connects with the wooden veneer of the car door to form a continuous curve, creating a sense of intimacy similar to sitting in the living room at home. All the wood decorations are made by hand, then hardened for 72 hours, and finally coated with varnish, so that the natural beauty of the wood can be better presented. The new interior contains 600 new parts, while a few parts, such as sunshades, door handles and seat armrests, are the same as those of the previous generation.
