Hot plate hot fusion welding: thermoplastic welding equipment using surface heat conduction melting to weld the surface of plastic workpiece. It is not limited by the material and size of the parts, and the welding seal is good. It is suitable for the welding of large special-shaped workpieces such as airbag, dashboard, sunshade, car water dispenser, taillight, expansion water tank, brake oil cup and so on.
For a long time, Emperor Chen Yu doors and windows have always been committed to home doors and windows heat preservation and energy conservation, sunshade and thermal insulation work. The broken bridge window system selects scientific and reasonable sealing profile, flexible adhesive strip seamless sealing lap joint, super-large glass hollow layer by layer protection, which can greatly improve the thermal insulation performance of the house, reduce the temperature of the room exposed to the sun, and reduce the influence of western sunlight.
Set up a sunshade during a camping picnic, also known as the canopy, to enjoy the natural scenery without worrying about being tanned by the sun. The small awning is about 12 square meters, can hold 4-6 people, the area is enough, the large one is up to 20 square meters, there is no pressure to accommodate about 10 people, no matter how big it is.
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. Car interior decorations include dashboards, ceilings, sidewalls, seats and other surface decorations, as well as curtains and carpets. 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.

Raising seedlings in arch shed: before the seedlings are unearthed, it is also necessary to keep the soil moist, which is conducive to maintaining a high emergence rate. We have said that the summer and autumn seedlings cover the sunshade net, wait until the seedlings are all out, it is necessary to open the sunshade net in time to avoid the emergence of tall seedlings. In addition, because there is more rain in summer and autumn, we should also pay attention to avoid the seedbed being drenched and waterlogged by Rain Water, which is not conducive to seedling emergence. If there are continuous rainy days during the seedling period, we can properly apply paclobutrazol to control the seedlings and promote the growth of the seedlings. When raising seedlings in winter, the overall temperature is relatively low, so we can cover grass curtains or quilts on the arch shed to keep warm to ensure that seedlings emerge neatly.
The Edge office building, built on a 15-meter-wide site with a total of 10 stories, is currently the largest building with a solar wall facade in Canada. The 560 photovoltaic panels on the facade of the building can meet 80% of the power needs of the building. At the same time, the building is also connected to the local urban power grid to transfer its excess electricity. The design of the building includes two insulated three-layer glass and four-layer glass systems. The sunlight from the north side also fully meets the needs of indoor lighting during the day. The north window does not need to install any blinds to withstand the high temperature caused by the sun in summer. The rear end of the office building is also equipped with a thermal isolation balcony and sunshade to better control sunlight exposure.
Plastic polyvinyl chloride (PVC) material is widely used in the manufacture of decorative skins and protective covers such as automobile dashboards and sunshades because of its low price and simple processing. However, in order to meet the relevant production requirements, PVC formula contains plasticizers of phthalic acid, heavy metals and other toxic substances; in addition, although PVC material itself is non-toxic, it will slowly decompose harmful hydrogen chloride gas at high temperature.
Take emergency measures for disaster prevention and reduction. Pay close attention to weather changes and timely do a good job in preventing extreme weather emergencies such as low temperature and frost damage and snow disasters. Before the strong cold air comes, the greenhouse facilities should be strengthened in time, the air leakage of the film should be repaired, and multi-layer covering should be used to keep warm at night. 0.2% potassium dihydrogen phosphate solution was sprayed on the leaves at low temperature for 1-2 times to enhance plant resistance. After strong cold air, the management of ventilation, light, humidity reduction, disease prevention and extra-root topdressing should be strengthened, watering should be strictly controlled, humidity in the greenhouse should be reduced, and plant growth should be restored as soon as possible. Plants are prone to water loss and wilting in fine weather. Sunshade nets or non-woven fabrics can be used to cover the sun, heat up slowly, gradually increase light, and prevent plants from withering and dying. Open-field vegetables can be tied up according to the situation, floating cover sunshade net, straw and other to prevent frost injury, rain and snow weather can rush to harvest some vegetables, stored in indoor batches on the market.
In the design and development of interior fabric, we often use fiber materials with fine denier and high hole to reduce the rigidity of the fiber and increase the soft touch of the fabric. at the same time, we can also use different yarn shrinkage to achieve the shrinkage elasticity and thick feeling of the fabric; in order to ensure the straightness of the sunshade fabric, we need to stiffen the fabric. In order to increase the friction coefficient of the seat synthetic leather surface, we choose the surface embossed texture with a strong sense of particles; in the coating of the dashboard or door panel area, in order to meet the delicate comfort in the process of use, we often use fine frosted texture and matte gloss treatment at the same time.
To reduce direct sunlight radiation from roofs, walls, windows and indoors through windows, eaves, sunshades (awnings), coated glass, etc., can be used to reduce the radiation heat of sunlight absorbed by external walls and roofs, and light-colored exterior wall finishes can be adopted. the insulation layer is set on the outside of the external wall and roof, or overhead roofing and other measures.
Of course, the work of solar greenhouse requires the cooperation of a variety of equipment, with higher and higher temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied.
