The so-called “bright window action”, as the name implies, is the car window bright action. According to the relevant regulations, all car windows are not allowed to carry sunshade films with reflective properties, and the transmittance of ordinary refractive protective films should be more than 50%, that is, the transparency of window glass needs to be more than 50%. The film transmittance of the front windshield and exterior rearview mirror glass of all cars should be higher than 70%.
Wencheng County high-end dual-mode ultrasonic welding machine / motor lift [Today / Information] 2022 has been updated such as: speakers, dashboards, folders, lamps, vacuum cleaners, filters, electric mosquito pats, etc. Double-head ultrasonic plastic welding machine, can give full play to its welding effect when welding hard plastic materials, ultrasonic welding machine, special scope: used for car body plastic parts, car doors, car instruments, headlamps, mirrors, sunshades, interior decoration, filters, plastic electronic products: prepaid water meters, electricity meters, communication equipment, cordless phones, mobile phone accessories.
3. The exterior ornaments of the car body mainly refer to decorative strips, wheel covers, signs and embossed words, etc., and accessories such as radiator masks, bumpers, lamps and rearview mirrors also have obvious decoration. 4.

Surface finishing materials such as natural fiber or synthetic fiber textiles, artificial leather or multilayer composite materials, skin foam and so on are widely used in cars. On the bus, there are a large number of decoration materials such as fibreboard, cardboard, engineering plastic board, aluminum board, pattern rubber board and composite decoration board. 5, body accessories door locks, door hinges, glass lifts, various seals, windscreen wipers, windwindow scrubber, sunshade, rearview mirror, handle, cigarette lighter and ash box, etc. Radio recorders and pole antennas are often installed in modern cars.
Comprehensively do a good job in cold prevention and warmth protection, ensure that the three-layer thermal insulation cover of the inner and outer shed film and grass curtain is in place, and on this basis, add an inner arch shed apron, and use the abandoned agricultural plastic film or idle sunshade net in stock to cover the grass curtain or non-woven fabric, press the edge, cover it tightly, and set up a two-layer film in the greenhouse if possible. Dangerous shed or damaged and collapsed shed can harvest the vegetables in the shed and store them indoors in advance so as to reduce the economic loss as much as possible.
First of all, from the control system of the multi-span greenhouse, the electric sunshade, the electric film, the window, the ventilation, the electric insulation and the water curtain of the electric fan have been realized. The control ability of the greenhouse is more stable and reasonable, and the work efficiency is higher. There is no need for manual operation, just press the switch of the distribution cabinet. Looking at the production in some backward areas ten years ago and even now, this is a great progress for facility agriculture in our country. Secondly, our multi-span greenhouse can be equipped with mechanized automatic fertilizer spraying machine, automatic seeder and even Internet of things control is now a very common system, greatly improving production efficiency and realizing irrigation, fertilization, water and fertilizer saving, soilless cultivation and other protection of soil from pollution.
Indoor shading attaches equal importance to sunshade and decoration, generally divided into window decoration and cloth art. At present, there are quite a lot of varieties and colors of indoor shading in our country, and the shading effect is also different, but whether it is blinds, rolling curtains and cloth art, all the sunlight is treated after entering the room, and the heat island effect is formed between the curtains and the glass. The curtains have no sealing effect indoors, and the heat is easily diffused indoors. To reduce heat, the only way to reduce heat is to use air-conditioning for cooling. Indoor products are generally sunshade and uninsulated, so it is also hot without sunshine at night (of course, this has something to do with wall insulation). The use of outdoor way is to block the heat outdoors, so that outdoor air convection faster, so it will not form a heat island effect, outdoor sunshade materials should use materials that dissipate heat quickly, such as aluminum alloy 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.
In May, take advantage of the holiday, choose a lawn with three or five friends, under the comfortable sunshade tent, you can put on a red and white plaid picnic mat and bamboo rattan snack basket, or you can sit at the online celebrity ins omelet table, eat barbecue, play vulgar wine table games, and come to Yunlan Bay to find the beautiful spring light missed this year in the sunshine, flowers, food and laughter.
Sunshades protect telescopes, reflecting light and background heat from the sun, earth and moon into space. The observatory must maintain a low temperature in order to complete groundbreaking scientific research in infrared light, which is invisible to the human eye and feels like heat.
