Product Introduction
ZS-1 High temperature resistant thermal insulation coating It is the research achievement of Zhisheng Weihua for many years. It has the coating R&D technology. After more than ten years of R&D and application, the coating technology has been greatly improved. ZS-1 high temperature resistant thermal insulation coating is a series of space energy-saving thermal insulation coating. Zhisheng Weihua space energy-saving thermal insulation coating includes ZS high temperature type and ZS normal temperature type, ZS-1 high temperature resistant thermal insulation coating can be divided into three types according to different use conditions: (- 60 ℃～ 600 ℃, wet specific gravity is 1200Kg/m3), (- 60 ℃～ 1000 ℃, wet specific gravity is 1000Kg/m3) and (800 ℃～ 1800 ℃, wet specific gravity is 2200Kg/m3). The thermal conductivity coefficient of these three types of coatings is only 0.03W/m.K (measured at 70 ℃).
ZS-1 high temperature resistant thermal insulation coating, with temperature resistance of 1000 ℃, is a synthetic silicate solution specially prepared by Zhisheng Weihua Aluminum silicate Fiber, heat reflective material and selected hollow ceramics It is made of fine beads. The paint is an inorganic single component, without any odor and harmful substances under high temperature and normal temperature.
The main function of the coating is to prevent heat conduction. The thermal conductivity coefficient is only 0.03W/m.K. The coating can effectively shield radiant heat and heat conduction. The thermal insulation efficiency can reach about 90%. It can prevent the heat radiation and heat loss of high temperature objects, effectively keep cold for low temperature objects and prevent the loss of cooling capacity caused by environmental radiant heat, and also prevent the generation of condensate water from objects.

working principle
The silicate inorganic solution specially made by Zhisheng Weihua is selected as the film forming material of the high temperature resistant thermal insulation coating, filler Nano hollow ceramic beads, aluminum silicate fibers and heat reflective energy-saving materials are selected as solid materials. ZS-1 coating is composed of inorganic materials. The content of hollow ceramic beads reaches more than 80%, and the volume of ceramic beads is more than 80 meshes. 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 the thermos. The thin coating is equivalent to hundreds or thousands of thermos, and has good thermal insulation effect. 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 technical R&D and innovation, it is not simple static air or vacuum between the beads in the high-temperature insulation coating, 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 more effectively prevent the conduction of heat 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.
