Office partition wall aluminum-for sale, built-in louver partition, the aluminum shutter is installed in the hollow cavity of hollow glass, through magnetic drag, to realize the folding and dimming function of the built-in shutter. The technology combines the hollow glass indoor curtains of the external sunshade device into one, which has the effect of all. The louver partition is a louver built in hollow glass, which can realize the rise and fall of the louver, reasonable structure and simple operation. It has good shading performance, improves the insulating performance of insulating glass, improves the indoor light environment, and is widely used in energy-saving building doors and windows.

Winter tea is dormant, generally low temperature overcast and rain has a limited impact on tea, but if it encounters wind and freezing or extreme low temperature, it will affect tea tree winter and spring tea production in the coming year. One is to cover and keep warm. Can be in the cold air before the tea cover surface covered with rice (miscellaneous) grass, sunshade net and so on. The second is to build barriers and guard against the wind. For the land easily affected by wind freezing, sunshade nets and other materials should be used in advance to establish wind barriers in the windward, which is higher than the 20cm of tea canopy and tilted to the direction of tea trees. The third is to restore the tree situation in time. For the heavily frozen tea garden, it is appropriate to make trees after the beginning of spring, rather than deep pruning and pruning, and strengthen the management of spring tea fertility.

Class prepares picnic cloth and tent in group form; asks parents to put on comfortable and cool clothes and sunshade hats for children on that day; prepare a kettle, a healthy picnic food (sandwiches, sushi, pizza, water ghost salad, etc.); Creative DIY, ask children to bring watercolor pens, marker pens, paints and so on.

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.

Generally speaking, the outer sunshade can keep most of the solar radiation out of the window, while the inner sunshade only partially reflects the solar radiation that has entered the room. Although the effect of external shading is much better than internal shading, internal shading is still widely used, mainly in the form of curtains and blinds. The main forms of external shading are sunshades and sunshades and so on.

Greenhouse heat preservation should be done a good shading work, greenhouse heat preservation in the hot season greenhouse vegetable cultivation should adopt shading cover measures, commonly used shading equipment is sunshade, shading should be selected according to plant species. Short plants choose black shading net to choose gray shading in autumn and winter vegetable cultivation. Because the gray shading can prevent the growth of insects, if the seeds or film delay the cultivation of plants need to use the network. On August 7, when the weather is hot, it can be used in the sunshade net, which is relatively weak in the cold season, does not need lighting or no curtain, and does not shade in the heavy rain season. The heat preservation time of the net greenhouse is not long, and the plants are covered on the surface, especially the dark shade opens the daylighting. When growing mushroom crops, greenhouse heat preservation will not cause fungal crop infection, and the products can be recycled.

Air-conditioned buildings rely on refrigerators to move the indoor heat load to the outside in summer. Obviously, if the indoor heat load is reduced, the running time of the refrigerator will be reduced, and the energy consumption of the cooling tower system will be reduced. The indoor heat load comes from two aspects, one is the heat exchange caused by the indoor and outdoor temperature difference, and the other is the heat load caused by indoor lighting and equipment. Therefore, sunshade, airtight, thermal insulation and other methods can be used to reduce indoor heat load and achieve energy saving. 1, reduce indoor heat load (1) sunshade to reduce direct sunlight radiation roof, wall, window and through the window to enter the room, you can use eaves, sunshade panels (awnings), coated glass, etc.; reduce the heat radiation of the external walls and roofs, you can use light-colored exterior wall finishes to set the insulation layer on the outside of the external walls and roofs, or overhead roofs.
