Standard for the application of rubber and plastic insulation materials in the refrigeration industry
The rubber-plastic insulation board has high elasticity, so it can greatly reduce the vibration and rubber-plastic plate resonance of the chilled water and hot water pipes during use. The flexible rubber and plastic insulation board has good winding and toughness, and it is easy to handle curved and irregular pipes during construction, and it can save labor and materials. Easy to install, beautiful appearance Because of the softness of this product, easy to install. Pipe installation: It can be installed together and installed. For complex parts such as valves, tees and elbows, the plates can be cut and bonded according to different shapes to ensure the tightness of the whole system, thus ensuring the thermal insulation of the whole system. . Because of the smooth and flat rubber surface and the excellent performance of the material, it does not need to add a vapor barrier layer and a protective layer to reduce the trouble in construction and ensure a beautiful appearance and smoothness. When the equipment or pipeline is overhauled, the stripped material can be reused and the performance is unchanged. Other advantages Rubber and plastic insulation tubes are safe to use, neither irritating to the skin nor harming health. They prevent mold growth, prevent pests or rats from biting, and are resistant to acids and alkalis and have superior performance. These properties make rubber and plastic an ideal insulation material for protecting pipes from corrosion due to atmospheric media or industrial environments.
There are several characteristics of rubber and plastic insulation pipe insulation board, which is the fire safety factor of rubber and plastic insulation pipe foam is relatively high. And it has the characteristics of large rigidity, light capacity, good heat insulation and good dimensional stability. Its expansion coefficient is similar to that of aluminum, and it is a kind of incombustible substance. It produces less carbon monoxide when burning, and does not drip things, does not melt, and has a low amount of smoke. It is a product with relatively high cost performance.
According to the characteristics of rubber and plastic insulation pipe insulation board, it is divided into the following eight categories:
1. High fireproof performance: Rubber and plastic insulation pipe insulation board has the characteristics of being incombustible and non-combustible. Its combustion performance can reach the national standard, and the high temperature that can be used is 180 °C. The foam structure within the layer is well protected.
2, better thermal insulation performance: can be insulated, heat insulation, low thermal conductivity.
3, heat-resistant time: rubber and plastic insulation pipe insulation board has a high thermal stability, can be used for a long time at 150 °C.
4, anti-corrosion and anti-aging performance is good: long-term exposure to sunlight, and no obvious aging phenomenon. Therefore, the aging resistance is better.
5, the density is small, the weight is extremely light: rubber and plastic insulation pipe insulation board has a density of 80kg / m3 or less, can reach 50kg / m3 or so. And the construction is simple and fast, and the work efficiency is improved.
6, the applicable temperature range is wide: the strength of the rubber insulation tube foam insulation board will not change due to temperature changes.
7. Excellent sound absorption performance: The sound absorption performance of rubber and plastic insulation pipe insulation board is good.
8, absolutely environmental protection: rubber and plastic insulation pipe insulation board has the characteristics of not polluting the environment.
How to choose rubber and plastic insulation pipe is a problem that plagues many customers. As the saying goes: "One point for a price", is the price of the high rubber insulation pipe is good? It is not so general to say that some businesses will seize the people's psychology and deliberately increase the price of products of poor quality to the purpose of sales. Of course, we must consider the price of the product when we buy something, and the cost-effective product is the right choice for Zui. So how do you choose rubber and plastic insulation pipes? From the following aspects:
1. Insulation performance: The rubber-plastic insulation pipe required to be used has good insulation performance and is not easy to dissipate heat. The surface is pasted with aluminum foil and other veneers to keep warm, moisture-proof, radiation-proof, and certain decorative.
2. Thermal insulation and sound insulation: It requires heat preservation and sound insulation of air conditioner ducts and other air ducts of different specifications. The surface can be affixed with aluminum foil, etc. It has good thermal insulation effect, light weight, flame retardant, anti-vibration and sound absorption.
3. Seismic performance: The rubber-plastic insulation pipe is required to have high elasticity, which can reduce the vibration and resonance of the chilled water and hot water pipes during use.
4. Flexibility: The rubber and plastic insulation pipe is required to have good bending and toughness. It is easy and convenient to install in different installation environments, and it can save labor and materials.
5. Safety: Rubber and plastic insulation pipes are required to be safe to use, which will not produce toxic gases or irritate the skin. It also prevents mold growth, rodent bites such as rats.
6. Acid and alkali resistance: The rubber and plastic insulation pipe is required to have good corrosion resistance, superior performance and long service life.
