4. Greenhouse management: first, we should do a good job of anti-freezing. Freezable flowers can be equipped with an inner film in the greenhouse to form a two-layer film for heat preservation, and heating can also be carried out in the greenhouse if possible. Second, it is necessary to do a good job in strengthening the greenhouse. On snowy days, when there is snow in the greenhouse, we should remove the snow from the roof in time, increase the light transmission, prevent the greenhouse from being crushed by the snow, and reduce the freezing low temperature after the snow melts. When clearing the snow, you should avoid piercing the greenhouse film and transport the snow out of the nursery. The greenhouse with collapse and collapse deformation should be strengthened and repaired immediately, and if it cannot be repaired, the plants in the shed should be transferred in time, or covered with film, grass curtain or sunshade net to improve the heat preservation effect.

Architects attach great importance to the physical environment of academic buildings. The whole building is almost completely wrapped in glass curtain walls, ensuring transparency and interactive experience, while introducing daylight for daily work and research, and the space that does not need daylight is located in the middle of the building, reasonable functional distribution and effective use of natural light reduces the energy consumption caused by artificial light sources. Architects deal with the building shell in an ingenious and innovative way, using double-layer low-iron toughened glass and mechanical sunshades with a total thickness of 41 cm for mechanical ventilation to isolate subway noise and create a quiet learning environment. at the same time, a thermal buffer zone outside the building is formed, which further improves the comfort of the internal environment.

At present, spray-free plastics have been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts in the automotive field. Bioplastics bioplastics are produced by using original plants as raw materials, such as sugar cane and corn, under the action of microorganisms. Commonly used plastics are generally synthesized from petroleum products, and there are often 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, greatly reduce the amount of VOCs volatilization in the car after being prepared into automobile interior parts. In addition, this bioplastic can be decomposed to facilitate subsequent recycling, so it is a more environmentally friendly type of plastic. News:

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.

Hubei Jingzhou lifting PZ7I automatic feeding shotcrete truck manufacturer “leather causes interests and challenges in the value chain and exists on the automobile. Leather is endowed with the meaning of high-end luxury. At present, it has become the mainstream trend to be used in seats, steering wheel, shift knob, door decoration, dashboard, sunshade, headrest and other automobile interior parts, scientific research equipment procurement reform, Guangxi actively responded in recent years, frequently support scientific and technological innovation policies. The “loosening” of scientific research funds, especially the free purchase of scientific research instruments and equipment, can pack costs and save storage and transportation costs for loose products, such as cotton, tobacco, silk, hemp, etc., compressed and packaged by compression packaging machine, which can greatly reduce the volume and thus the cost of packaging. The performance of some of these products has reached or close to the advanced level, and this progress has effectively broken the monopoly position of some imports in some fields,

The so-called “bright window action”, as the name implies, is the car window bright action. According to the relevant regulations, all car windows are not allowed to carry sunshade films with reflective properties, and the transmittance of ordinary refractive protective films should be more than 50%, that is, the transparency of window glass needs to be more than 50%. The film transmittance of the front windshield and exterior rearview mirror glass of all cars should be higher than 70%.

The concrete structure built in 1963 is a huge thermal bridge, and the limestone exterior walls and lack of insulation pose challenges to the energy consumption of the building. Skylights with fixed sunshades provide passive heat and natural light for the four-story atrium. Program-controlled blinds fall at night to reduce heat loss.
