Under the premise that Ningdu meets the design requirements of the building, adding external sunshades, awnings and appropriately increasing the length of the southward balcony can play a certain sunshade effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which has a decorative effect on the front, forming a less mobile space layer about 50mm thick between the glass and the curtains. In this way, a good effect of thermal reflection and thermal insulation can be achieved, but the direct lighting is poor and should be made into a movable type. In addition, installing blinds with certain thermal reflection on the inside of the window can also obtain a certain thermal insulation effect.
Car shipping companies always pay attention to the sound affected by high temperature and humidity. Now most cars are equipped with CD equipment. The main factors that affect the normal work of car audio in autumn are high temperature and humidity. Because the car audio is mostly installed in the upper part of the dashboard, in order to avoid the exposure of the sun, the effect of using sunshade is better. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine.
The technical proposal adopted by the utility model for solving its technical problems is that a sunshade picnic heat preservation package comprises a package body, the top of the package body is provided with a circle opening and a cover connected with the opening through a zipper, two symmetrical straps are arranged on both sides of the package body, and an integrated plastic skeleton is arranged on the side wall and the bottom of the package body. The plastic skeleton comprises a chassis matched with the bottom of the inclusion body and a support bar supporting the four corners of the inclusion body vertically around the chassis. The inner wall of the inclusion body is provided with an aluminum film thermal insulation lining layer, which can be used for high temperature heat preservation and low temperature heat preservation, and the effect is good. One corner of the inclusion body is provided with a cylindrical groove arranged in the inclusion body, the bottom of the groove is provided with a base, and the base is provided with a retractable umbrella handle. The retractable umbrella handle is provided with a sunshade, which can be used as an umbrella when the sun is strong or it rains.
Three major cooling measures for greenhouse. If winter is over, can summer be far behind? With the increase of summer temperature, how to cool the greenhouse properly has become an important work of daily management. Below, the editor of Tengchong greenhouse will introduce the following six cooling measures. First, external sunshade system. In order to minimize heating costs and improve efficiency, how to enhance the heat preservation capacity of Baoshan greenhouse and reduce heat loss has become a concern of many greenhouse users. Is to cover the excess sunlight outside the greenhouse to form a shade to protect the crops in the greenhouse, so that the temperature in the greenhouse is kept at a suitable temperature. This can effectively block direct sunlight crops without affecting the natural ventilation in the greenhouse, and the cooling effect is better than that of internal shading, but external shading materials are required to be sturdy, durable, flexible and anti-aging
In addition, some small equipment can also make the car less suffering from the hot sun, such as anti-explosion film, explosion-proof film with ultraviolet reflection and other functions, better thermal insulation effect. Car sunshade is also a good choice, car sunshade can reflect heat to achieve the purpose of cooling, if the front window glass covered with sunshade, can reduce the heat by more than 70%.
At present, spray-free plastic has been successfully used in the automotive field of side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other auto parts. Bioplastics bioplastics are produced under the influence of microorganisms using original plants as raw materials, such as sugar cane, corn and so on. Most of the commonly used plastics are synthesized from petroleum products, and there are usually small molecular harmful substances that do not fully react, while bioplastics, due to the use of renewable raw materials with low toxicity and low harm, can significantly reduce the amount of VOCs volatilization in the car after being prepared into automobile interior parts. In addition, this bioplastic can be broken down to facilitate subsequent recycling, making it a more environmentally friendly plastic category.
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.
