One of the simplest items in the high temperature test is the exposure test, in which the vehicle is parked in the hot sun with the front facing west, and the temperature display patch is affixed to the critical parts of the vehicle, such as engine cover, dashboard, deflector, and so on, and the temperature in the car is as high as 70 or 80 degrees. Then test the door handle, dashboard, sunshade, air conditioning outlet and other internal and external accessories for abnormal sound or efficacy failure.
Although the solar greenhouse has a very good thermal insulation performance, but from the point of view of safety, heating equipment is still an important factor. The southern part of our country generally does not need to heat up, but if we encounter bad weather continuously, we still need to use the energy stored in the greenhouse itself, otherwise it will not be able to meet the growth of vegetables. Therefore, whether in the south or north, heating equipment has always been a necessary protective measure. The technical aspect requires that in the equipment configuration of solar greenhouse, the configuration of thermal insulation equipment should be demonstrated in great detail. Of course, the work of glass greenhouse in Tibet needs the cooperation of a variety of equipment, with the increasing temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system, window opener, fan, wet curtain and other equipment need to be applied. For more information about the cost of glass greenhouse in Tibet, please contact Minghao greenhouse Engineering Construction Company directly.
The construction of glass greenhouse has always been a concern of crop planting places, multi-span greenhouse breeding greenhouse, border surface poured with bottom water before sowing. Gently rake the topsoil with a tooth rake to sow the seeds into the soil, cover the border with a layer of plant ash, and cover the sunshade net with straw or a small arch shed after sowing in summer and autumn to prevent erosion by high temperature and torrential rain. Keep the soil warm and moist for 6-7 days, and the winter sowing temperature is on the low side, then cover the border with plastic film or sunshade net to promote seedling emergence, remove the seedlings after emergence, and make the circular movement into a linear movement. the aluminum drive card connected to the drive wire drives the edge aluminum profile to move parallel on the cord through cross-connection, driving the edge aluminum profile to pull up one end of the curtain cloth and slowly unfold and close. That is, all aluminum drive cards turn off the limiter switch after closing. When the motor stops working and the operation ends, the facade side roll sunshade insulation system forms a complete sealed space composed of sunshade and thermal insulation curtains in the solar greenhouse.
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.
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.
Some time ago, a Jiangsu user bought a straw hat for my summer sunshade. After receiving the goods, he said that the thing you sent me was bad and asked for a refund. I saw the picture he sent showing the opening of the side line. We will check the goods one by one, it is impossible to have such a bad situation, it is useless for you to argue with him, and then say to him, how about I compensate you some money or give you another one? He said, then send me another one. When you send it, you must send it well. I said, of course, I am relieved to send you a good one. Then I sent him another one, thinking it was a thing of the past.
The heat preservation work in the greenhouse can be completed by side insulation and top insulation curtain, as well as internal and external sunshade curtain and top skylight. The heat preservation work can be carried out 2 hours before sunset. Close the top skylight 2 hours before sunset, expand the internal heat preservation, and then gradually expand the internal sunshade and side insulation. All the internal heat preservation, inner sunshade and side heat preservation will be carried out before sunset. If necessary, external shading can also be fully carried out for thermal insulation. When the external solar radiation is less than 300W/m2 (blade stomata closed) and need heat preservation, you can directly turn on internal heat preservation, side heat preservation and internal shading, and close the top skylight at the same time.
