The installation of sunshade net in the greenhouse in Xuanhua County, Zhangjiakou City, a detailed interpretation of the good or bad work of heat preservation and cold protection in the greenhouse design will be directly related to the vegetable production next year, while the heat preservation work of the greenhouse in winter is not prone to problems. The problem of heat preservation and cold protection of vegetables in greenhouse design is particularly important with the advent of winter, so we should especially remind the vegetable growers in greenhouse that before the cold of winter, we must do a good job of heat preservation and cold protection. Physical, chemical, agricultural and other comprehensive measures to do a good job of heat preservation and cold protection, which is extremely important to promote the normal growth of vegetable plants and improve the output value and quality of vegetables.
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.
Car interior accessories include dashboard, door guard, steering wheel, seat, ceiling, floor mat, sunshade, storage box, ashtray, etc., as well as some ancillary equipment such as audio, air conditioning, communications, television, lighting and so on. All kinds of equipment, function, shape and structure are very different, how to combine them organically to form a unified, coordinated and beautiful design? These are all things that designers should consider.
Generally speaking, the horizontal sunshade with an outdoor south elevation of 45 °can easily cover 68% of the solar radiation heat. Installed in the window inside the curtain, soft 100 pages and other sunshade facilities, most of the solar radiation heat absorbed by it is distributed to the indoor air. The sun visor installed on the outside absorbs most of the radiant heat and distributes most of the outdoor air, thus reducing the impact on indoor temperature. Therefore, the use of external sunshade (sunshade) is the best way to save energy in buildings.
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.
First, all kinds of accessories in the new car. The first category is the seat category. Including car seat cushion, seat backrest, seat cover and seat fabric, headrest and other materials; the second category is interior decoration. Including the car floor, door guard, side guard, rear guard, roof lining, curtains, floor cover, etc.; the third category is the functional category. Including car body insulation materials, anti-collision fillers, dashboards, sundries, indoor shelf panels or rear windowsill panels, sunshade panels, wheel cover covers, engine cover covers, etc.
The advantage of Sanya Bay is that the place is large and the seaside scenery is beautiful. Take the natural coconut tree as a sunshade and spread the picnic to a shop on the beach. When you are tired, you can lie under the tree and have a rest. Sanya Bay, there are many small pavilions, lying on it, pose, a proper “Maldives” wind!
The car key door can be pulled out in two different gears, one of which is powered by a CD player. I just got it and changed a battery when I ran out of power. When I first got it, there was a noise in the back of the rear seat, the right rearview mirror was loose, the electric adjustment of the rearview mirror failed, the speedometer did not work (the fault was cured after changing the battery), the CD machine did not read the disc smoothly, and the front fog light was not lit. The rearview mirror reading lights and sunshade make-up mirror lights are not lit (the front car owner did not connect the line when the roof was packed), the rising window of the right front window was slow, and the valve chamber cover and steering power tubing leaked oil.
Summer is coming, and the sun is getting hotter and hotter. Sometimes I park my car in the sun for a while and then go in. It feels like a sauna, and the seat is very hot. At this time, you will see a lot of people put the sunshade on the front windshield. Does this really work? Can the sunshade be insulated?
You can directly fill the roof with soil to grow vegetables in a large area, or you can use containers to grow vegetables. It is recommended to plant luxuriant vine crops to cover the entire roof. Growing vegetables on the roof must be based on the premise of good load-bearing on the roof, and crops can not corrode concrete buildings. Each pair of ceiling curtain is composed of left and right guide rails, which drive the track when the motor starts, and the fabric is drawn by an elastic guide shaft in the middle to achieve the purpose of sunshade. Sun room sunshade system if the daylighting of the balcony at home is on the medium side, it is recommended not to use full shading curtains, but to use semi-shading curtains, so it is appropriate to choose whether shading is needed or not. The color of the space tends to be simple and pure. Plus the silver-gray sunshade looks like a perfect match. It can be a straight line or an arc. According to the architectural characteristics of the building, we use straight-line double-track ceiling curtain. It is not only practical for shading, but also maintains the style of architectural design.
In order to achieve the welding effect, we can weld multiple points in the same spot, cut and seal, and use the working rules of ultrasonic instantaneous vibration to cut chemical fiber fabric. the highlight of this method is that the incision is smooth, non-cracking and non-wiredrawing. Electric energy is converted into mechanical energy by ultrasonic vibration. Energy is transferred to the contact surface of the plastic workpiece through HORN, resulting in the principle of strong intermolecular friction and heat generation. The product will immediately melt and integrate into the same 360 degrees. Such as: speakers, dashboards, folders, lamps, vacuum cleaners, filters, electric mosquito rackets and so on. 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.
