Description

Technical Field

[0001] This utility model belongs to the field of heating materials technology, and in particular relates to a double-sided heating material. Background Technology

[0002] Heating materials play an indispensable role in many fields of industrial production and daily life. Whether it is drying and heat treatment in industry or heating and cooking in the home, specific requirements are placed on the performance of heating materials. However, traditional heating materials have revealed many problems that need to be solved in practical applications.

[0003] Traditional heating materials are mostly designed for single-sided heating. In some industrial drying equipment, if the material needs to be dried quickly on both sides at the same time, single-sided heating is not only time-consuming, but also leads to uneven drying on both sides, affecting product quality. In complex operating environments, corrosive substances such as acids and alkalis can easily corrode the heating materials, causing damage to their internal structure and performance degradation. Long-term exposure to humid environments can also cause the materials to rust and short-circuit, greatly shortening their service life.

[0004] To address these issues, we provide a double-sided heating material. Utility Model Content

[0005] The purpose of this invention is to provide a double-sided heating material, which solves the problem that most existing heating materials are designed for single-sided heating. In complex operating environments, corrosive substances such as acids and alkalis can easily corrode the heating material, leading to damage to its internal structure and a decline in performance.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This invention relates to a double-sided heating material, comprising a heating layer body, which includes an alloy conductive layer. An infrared generating layer is fixedly connected to the surface of the alloy conductive layer. A protective layer is fixedly connected to the surface of the infrared generating layer. An acid and alkali resistant coating is fixedly connected to the surface of the protective layer. A fixing layer is fixedly connected to the surface of the acid and alkali resistant coating. A Teflon insulating layer is fixedly connected to the surface of the fixing layer. This double insulation design of the fixing layer and the Teflon insulating layer ensures that the material has extremely high insulation performance, effectively preventing electric shock accidents. Even under harsh conditions such as high temperature and humidity, it can protect the user's personal safety. Simultaneously, it provides precise heating area control and good heat dissipation performance. This reduces the risk of fire caused by localized overheating, providing a safer operating environment. The tight bonding between the various material layers and the fixing effect of the mica sheets make the entire material structure less prone to deformation during use. This stable structure maintains stable heating and protective performance, and can maintain high heating efficiency and reliable protective effect even after long-term use. It does not require frequent maintenance and adjustment, improving the reliability and stability of the equipment. Mid-wave infrared rays have less energy loss during heat transfer, and combined with high heating efficiency, this material consumes less energy than traditional heating materials to achieve the same heating effect, which is in line with the current trend of energy conservation and environmental protection, and helps to reduce energy consumption and operating costs.

[0008] The present invention is further configured such that the alloy conductive layer is made of an alloy material, namely a copper-nickel alloy. The copper-nickel alloy has a low temperature coefficient of resistance, which means that its resistance value changes relatively little with temperature and can maintain relatively stable resistance characteristics over a wide temperature range, thereby ensuring the stability of heating power. At the same time, it has good corrosion resistance and can work normally in some humid or corrosive environments, thus extending the service life of the alloy conductive layer.

[0009] The present invention is further configured such that the infrared generating layer is made of rare earth oxide material, and the infrared generating layer generates mid-wave infrared rays with a wavelength range of 3-5μm. When the alloy conductive layer generates heat and the infrared generating layer reaches a certain temperature, the atomic energy levels in the rare earth oxide undergo transitions, generating mid-wave infrared rays with a wavelength range of 3-5μm, which radiate to both sides. Mid-wave infrared rays have strong penetrating ability and can penetrate deep into the interior of the heated object, causing the object molecules to resonate and start heating from the inside, which greatly improves the uniformity and efficiency of heating.

[0010] The present invention is further configured such that the protective layer is made of glass fiber material, and the surface of the protective layer is fixedly connected with reinforcing protrusions. Glass fiber material has the characteristics of high strength, high temperature resistance, and corrosion resistance. Its high strength can effectively prevent the internal alloy conductive layer and infrared generating layer from being damaged by external forces such as scratches and collisions. Its high temperature resistance allows it to withstand the high temperature generated by the alloy conductive layer and infrared generating layer without changing its performance. Its corrosion resistance helps to resist the erosion of external chemical substances.

[0011] The present invention is further configured such that the acid and alkali resistant coating is made of an acid and alkali resistant spraying material, which is a fluoropolymer and a curing agent. The fluoropolymer has excellent chemical stability and good resistance to most acids and alkalis. The role of the curing agent is to enable the fluoropolymer to form a strong and dense coating structure after coating. In some environments where it may come into contact with acid and alkali substances, it can effectively prevent acid and alkali from corroding the internal structure and extend the service life of the heating material.

[0012] The present invention is further configured such that the fixing layer is composed of natural mica sheets, and the Teflon insulating layer is made of polytetrafluoroethylene material. The mother sheet has good insulation properties and its resistivity is extremely high, which can effectively prevent current from passing through and reliably insulate the heating part from the outside world to prevent the user from being electrocuted. Polytetrafluoroethylene has excellent insulation properties and its dielectric constant is low, which can effectively isolate the electric field and further enhance the insulation effect of the material.

[0013] The present invention is further configured such that the acid and alkali resistant coating is applied to the surface of the protective layer by spraying, with a coating thickness of 0.2-0.5mm. The spraying process is used to evenly coat the acid and alkali resistant coating material onto the surface of the protective layer, making the coating more uniform.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model utilizes the heat generated by the alloy conductive layer to induce the infrared generating layer to radiate mid-wave infrared rays to both sides, achieving efficient double-sided heating of the material. This enables rapid and uniform temperature increase of the heated object. Compared with traditional single-sided heating materials, the heating efficiency is significantly improved, and the target temperature can be reached in a shorter time, significantly improving production efficiency or user experience. The efficient heat transfer characteristics of mid-wave infrared rays make the heating more thorough and uniform, effectively preventing local overheating or undercooling of the heated object, thus improving product quality or user comfort.

[0016] 2. This utility model, through the combined action of a protective layer, an acid and alkali resistant coating, and a Teflon insulation layer, gives the material excellent protective capabilities, effectively resisting external damage. For example, it is not easily damaged by collisions or scratches in daily use, resists acid and alkali corrosion, and can maintain stable performance in harsh environments such as chemical plants. It can adapt to the influence of external environments and can work normally in humid environments or with different temperature changes. This greatly extends the service life of the heating material and reduces equipment maintenance and replacement costs. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figure 1-5 This utility model is a double-sided heating material, including a heating layer body 1, which includes an alloy conductive layer 101. An infrared generating layer 102 is fixedly connected to the surface of the alloy conductive layer 101. A protective layer 103 is fixedly connected to the surface of the infrared generating layer 102. An acid and alkali resistant coating 104 is fixedly connected to the surface of the protective layer 103. A fixing layer 105 is fixedly connected to the surface of the acid and alkali resistant coating 104. A Teflon insulating layer 106 is fixedly connected to the surface of the fixing layer 105.

[0027] Specifically, the double insulation design of the fixing layer 105 and the Teflon insulation layer 106 ensures that the material has extremely high insulation performance, effectively preventing electric shock accidents. Even under harsh conditions such as high temperature and humidity, it can protect the personal safety of users. At the same time, precise control of the heating area and good heat dissipation performance reduce the risk of fire caused by local overheating, providing higher safety for the use environment. The materials are tightly bonded together, and the fixing effect of the mica sheet makes the entire material structure less prone to deformation during use. This stable structure can maintain stable heating and protection performance. Even after long-term use, it can still maintain high heating efficiency and reliable protection effect without frequent maintenance and adjustment, improving the reliability and stability of the equipment. Mid-wave infrared rays have less energy loss during heat transfer. Combined with high heating efficiency, this material consumes less energy than traditional heating materials when achieving the same heating effect, which is in line with the current development trend of energy conservation and environmental protection, and helps to reduce energy consumption and operating costs.

[0028] Example 2

[0029] Please see Figure 1-5 Based on Example 1, the alloy conductive layer 101 is made of an alloy material, specifically a copper-nickel alloy. The infrared generating layer 102 is made of rare earth oxide material and generates mid-wave infrared radiation with a wavelength range of 3-5μm. The protective layer 103 is made of fiberglass material, and reinforcing protrusions 2 are fixedly connected to the surface of the protective layer 103. The acid and alkali resistant coating 104 is made of an acid and alkali resistant spraying material, which consists of a fluoropolymer and a curing agent. The fixing layer 105 is composed of natural mica sheets. The Teflon insulating layer 106 is made of polytetrafluoroethylene material. The acid and alkali resistant coating 104 is applied to the surface of the protective layer 103 by spraying, with a coating thickness of 0.2-0.5mm.

[0030] Specifically: Copper-nickel alloy has a low temperature coefficient of resistance, meaning its resistance changes relatively little with temperature, maintaining stable resistance characteristics over a wide temperature range, thus ensuring stable heating power. Simultaneously, it has good corrosion resistance, functioning normally in humid or corrosive environments, extending the service life of the alloy conductive layer 101. When the alloy conductive layer 101 generates heat and raises the infrared generating layer 102 to a certain temperature, atomic energy levels in the rare earth oxide undergo transitions, generating mid-wave infrared radiation with a wavelength range of 3-5 μm, radiating to both sides. This mid-wave infrared radiation has strong penetrating power, reaching deep into the heated object, causing molecular resonance and inducing internal heating, greatly improving heating uniformity and efficiency. The glass fiber material possesses high strength, high temperature resistance, and corrosion resistance; its high strength effectively prevents damage to the internal alloy conductive layer 101 and infrared generating layer 102. The material is resistant to damage from external scratches and impacts. Its high-temperature resistance allows it to withstand the high temperatures generated by the alloy conductive layer 101 and the infrared generating layer 102 without any change in performance. Its corrosion resistance helps resist the erosion of external chemicals. Fluoropolymers have excellent chemical stability and good resistance to most acids and alkalis. The role of the curing agent is to form a strong and dense coating structure after the fluoropolymer is coated. In environments where it may come into contact with acid and alkali substances, it can effectively prevent acid and alkali from corroding the internal structure and extend the service life of the heating material. Mica sheets have good insulation properties and extremely high resistivity, which can effectively prevent current from passing through and reliably insulate the heating part from the outside world to prevent electric shock to the user. Polytetrafluoroethylene has excellent insulation properties and a low dielectric constant, which can effectively isolate electric fields and further enhance the insulation effect of the material. A spraying process is used to evenly coat the acid and alkali resistant coating material on the surface of the protective layer 103, making the coating more uniform.

[0031] The working principle of this utility model is as follows: When the alloy conductive layer 101 generates heat and the infrared generating layer 102 reaches a certain temperature, the atomic energy levels in the rare earth oxide undergo transitions, generating mid-wave infrared rays with a wavelength range of 3-5μm, which radiate to both sides. Mid-wave infrared rays have strong penetrating power and can penetrate deep into the interior of the heated object, causing the object's molecules to resonate and start heating from the inside. The fiber structure of the protective layer 103 can prevent the heat from dissipating too quickly to a certain extent, playing a heat preservation role and further improving the heating efficiency. The mica sheets are connected to each other and fixed to the heating material by adhesive, making the entire material structure more stable and less prone to deformation due to external force or temperature changes.
