11. After the concrete has been poured, covering or spray curing should be carried out immediately before the initial setting. Concrete thermal insulation materials can be made of plastic film, geotextiles, gunny bags, flame retardant quilts and so on. If necessary, wind shielding shed or sunshade greenhouse can be set up. In the thermal insulation maintenance, the temperature difference and cooling rate of the concrete pouring body should be monitored on the spot, and when the measured results do not meet the requirements of the temperature control index, the thermal insulation maintenance measures should be adjusted in time.

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.

EPP (polypropylene) foam is a foam material formed by foaming with polypropylene resin as the matrix. It not only has high heat resistance, high impact energy absorption capacity, good resilience and thermoformability, but also can be recycled. It is widely used in bumper, bottom guard, sunshade and other automobile interior and exterior decoration parts. EPP is a kind of high crystalline composite material with excellent performance, which has become the fastest growing and most environmentally friendly anti-pressure buffer thermal insulation material because of its unique and superior properties. EPP can be used in construction, packaging, automobiles, sporting goods, toys, toolboxes, food packaging boxes, household appliances, daily necessities and so on. And EPP is included in the “made in China 2025” key areas of technical materials, known as “green” foam materials.

There are many kinds of automotive composites, including glass fiber mat reinforced thermoplastic composites. Natural fiber reinforced thermoplastic composites and carbon fiber reinforced composites are widely used in seat frames, bumpers, dashboards, engine covers, battery brackets, pedals, floors, protective panels, car ceilings, luggage brackets, sunshades, spare tire racks, etc., with the advantages of high strength, good durability, high reliability, low price, recyclable, degradable, renewable and so on.

To reduce the direct radiation of sunlight from the roof, walls, windows and enter the room through windows, eaves, sunshades (awnings), coated glass, etc., can be used to reduce the radiation heat of sunlight absorbed by external walls and roofs, and light-colored exterior wall finishes can be adopted. set the insulation layer on the outside of the external wall and roof, or overhead roof.
