What material is best for insulation!

Beijing Zhisheng Weihua company ZS-221 sunscreen heat insulation coating is a set of reflection, radiation and hollow beads insulation and one of the new cooling coating, the coating can be 400nm-2500nm range of solar infrared and ultraviolet high reflection, do not let the sun's heat accumulate on the surface of the object, and can automatically carry out heat radiation heat dissipation and cooling, the heat on the surface of the object radiation into space, reduce the temperature of the object, even in cloudy days and nights paint can radiate heat to reduce temperature, At the same time, hollow beads with very low thermal conductivity are placed in the paint to isolate the transfer of heat energy, and even when the atmospheric temperature is very high, it can also block the external heat and conduct it to the inside of the object, which ensures that the object painted with the paint is cooled down and the internal space of the object can maintain a long-lasting constant temperature. When sunlight is strong, the coating can reduce the surface temperature of the object by more than 20, and on cloudy days and nights, it can be cooled by more than 3 or reduce to the same temperature as the atmosphere.

The latest energy-saving and cooling curtain fabrics are developed and manufactured by Beijing Jinlanhai Nanotechnology.

Technical principle: There are three ways of heat transfer, conduction, convection, and radiation. The window absorbs heat and releases heat through the form of radiation, and the golden blue sea nano cooling curtain is a composite sunlight full-spectrum reflective material and infrared emission material on light fabrics such as tassel taffeta and oxford cloth, so that infrared, visible light and ultraviolet rays are reflected back through the window glass.

The energy-saving effect can reach more than 80%, the installation outside the window can reach more than 90%, and the sunny room can be reduced by 5-8 in summer.

Executive standard: The anti-radiation standard adopts the aircraft reflection standard, standard number:

It is the only energy-saving and cooling fabric with ultra-strict aviation standards at home and abroad.

3) Compared with other types of energy-saving and cooling curtains, the advantages are as follows:

Compared to aluminium foil fabrics:

The energy saving effect is more than 30%, and the service life is 20 years. The reason is that aluminum foil can reflect part of the visible light and infrared, but aluminum foil is a metal material, with good thermal and electrical conductivity.

Compared to silver-coated glue fabrics:

The energy-saving effect is more than 40%. The reason is that the silver glue coating is coated with an emulsion with ultra-fine aluminum powder, and the aluminum powder reflects heat and absorbs heat at the same time, and its emulsion is easy to be irradiated and aged by ultraviolet rays, and its fabric is thick and has a large heat capacity.

Compared with ultra-thin aluminum foil filament and chemical fiber, cotton and linen fiber blended fabrics

The energy saving effect is more than twice as high. The energy-saving and cooling fabric of the golden blue sea is a replacement for the gauze curtain or the special reflective radiation nano thermal insulation fabric installed by the window behind the gauze curtain, which is a simple and elegant nano white, light and waterproof without pores, and is a material integrating the reflection and emission function, and the aluminum foil silk blended fabric is a heavy decorative curtain, with obvious light and heavy colors and patterns, loose, breathable, strong heat absorption, ultra-aluminum foil filament is easy to oxidize and break for a long time, and the proportion in the fabric is small, and the positive outward surface has a reflection effect, and others can only play a role in heat absorption. Absorb ultraviolet rays and are prone to aging.

Test inspection methods.

Test method 1:

The thermal insulation effect of several fabrics is very simple, the heat absorption rate of the black body is more than 97%, take the asphalt linoleum, put different fabrics on the pure black asphalt board, irradiate it with a bath bomb lamp close to the sun for 2 minutes, or directly irradiate it in strong sunlight for 5 minutes, open the curtain fabric, test the temperature of the black body with an infrared thermometer, or directly touch it with your hands to know that the difference is very large.

Test method 2:

The surface temperature of the fabric is directly tested with an infrared thermometer, and the test temperature difference is also very large.

Test method three:

The above-mentioned samples are observed with an infrared thermal imager, and the worse the thermal insulation performance of the thermal insulation material, the more heat is absorbed, and the brighter it is under the thermal imager, and the darker it is.
