working principle

The high temperature resistant, heat insulation and thermal insulation coating adopts the silicate inorganic solution specially made by Zhisheng Weihua as the coating film-forming material, and the filler uses nano hollow ceramic beads, aluminum silicate fibers and heat reflective energy-saving materials as solid materials. The paint is composed of inorganic materials, α The content of phase hollow ceramic beads is more than 80%, and the volume of glass ceramic beads is more than 80 mesh. The air in the cavity of such hollow ceramic beads will not generate thermal convection after being heated, and the air layer between ceramic beads and ceramic beads will not generate thermal convection after being heated. There is no thermal convection when the object has a temperature difference. With pure inorganic materials as the support of the coating, the paint coating forms an insulation shield layer composed of static air and inorganic materials. With the help of heat reflective energy-saving materials, the thermal conductivity of the paint coating is close to the true space thermal conductivity, with low thermal conductivity and good thermal insulation effect.

The above structural structure of ZS-1 high temperature resistant thermal insulation coating is to create the thermal insulation mechanism of thermos. The thin coating is equivalent to hundreds or thousands of thermos, and the thermal insulation effect is very good. The fiber inorganic material is added to the coating, so the coating will not crack when it is brushed with a certain thickness every time, and the thermal frequency vibration resistance effect is good.

In the past few years of sales of ZS-1 high temperature resistant thermal insulation coating, Beijing Zhisheng Weihua Chemical Co., Ltd. has made three improvements on the basis of the original coating through continuous technical innovation by dozens of technical R&D personnel, tens of thousands of tests and inspections in the laboratory, and continuous feedback from customers on the application results on the site, The thermal insulation performance has increased significantly:

1. Adding natural active material into ceramic microsphere ceramic material can release ions with the same charge;

2. The ceramic bead wall is not a solid, but a certain amount of hollow body, that is, there is a certain static air layer in the ceramic wall;

3. The thickness of ceramic bead wall is more uniform; Through the above technological R&D and innovation, it is not simple static air or vacuum between the beads in the high-temperature insulation coating and between the beads, but there are a large number of ions with the same charge. The electromagnetic wave emitted by the ions with the same charge can effectively shield the electromagnetic wave of thermal energy, and can more limited prevent the conduction of thermal energy, Completely eliminate the free air layer. The thickness of the hollow layer on the ceramic bead wall and the bead wall is uniform, which can effectively reduce the resistance value of the thermal conductivity coefficient of the coating, and the compressive strength and expansion coefficient are more uniform.

The surface temperature of the painted object or equipment is 15~60 ℃, which cannot be directly painted on the surface of the running low temperature and high temperature objects. The ambient temperature of painting is higher than 5 ℃, and the construction is carried out in a ventilated and dry place.

2. The rust, oil and dust on the surface of the painted object shall be cleaned, and the construction can be started only after the moisture is completely dry. When painting on smooth or highly water permeable objects, it is recommended to apply ZS-1011 transition coating on the objects first, and then apply high temperature resistant thermal insulation coating after drying.

3. The thickness shall be selected according to the required thermal insulation effect, and the construction thickness of the first layer shall be about 0.3mm. In the future, the thickness of each layer can be more than 0.5mm, but not more than 1mm. In the case of multi coating construction, the subsequent construction can only be carried out after the previous layer dries, and the construction shall be carried out layer by layer until the required thickness.

4. If required by the customer, the coating can be applied on the inorganic primer specified by the customer, not directly on the organic primer.

5. For high-temperature pipeline and high-temperature equipment, the system can only be started after the coating is completely cured (generally more than 48 hours).
