What should be paid attention to in the installation of rubber and plastic insulation materials?

The equipment of rubber and plastic insulation materials should pay attention to the following points: 1. All the slits and joints need to be sealed and sealed with Dongyang brand special glue. 2. All three tees, elbows, valves, flanges and other accessories must reach the design thickness after installation. 3. Do not use too much force when bonding glue. The diameter of 4 pipes is larger. The interface between all materials should be bonded under slight extrusion. 4, the device should first the small tube after the small tube, first elbow, three-way straight tube, after the valve, flange. 5. When the device is chilled water pipe and refrigeration equipment, the gap between the two ends of the rubber-plastic pipe and the iron pipe shall be glued together, and the bonding width shall not be equal to the thickness of the rubber-plastic data. 6. The slit of the pipe should be installed in an inconspicuous place as far as possible, and the slits of the two pipes should be staggered from each other. 7. Do not install the machine while it is in use. Do not switch on within 36 hours of installation. 8. The large-diameter rubber-plastic tube has become elliptical due to the packaging relationship. Please cut the flat side when cutting. Second, the correct use of glue 1, shake the container before use, so that the glue is even, and then in the actual device, use a small tank of glue to prevent it from evaporating too fast, if necessary, can pour large cans into small cans, Seal the tank when not in use. 2. Use a short, hard brush. 3. Apply a thin layer of uniform special glue to the bonding surfaces at both ends of the material. 4. The natural drying time of special glue is 310 minutes. The length of time depends on the grade of glue, the temperature and humidity of the atmosphere, and the exposure time is more than 20 minutes. 5. When the glue is used, the glue is naturally dried. The correct method of measuring the dryness is “finger touch method”. The finger touches the rubberized surface. If the finger does not stick to the surface of the data, and the appearance of the data has no sticky feeling, it can be bonded. . 6. When bonding, just align the two outer surfaces of the adhesive interface for a while. 7. If the placement time is too long, so that the two joints are not sticky when pressed together, then repeat step 26 8. Normally, each kilogram of rubber and plastic glue can be applied with two square meters of bonding surface. 9. Generally, the special glue can't be used below 5 °C. When working in the environment of 5 °C - 10 °C, please put the glue in the room at 20 °C, and take it out when it is needed. 10. When connecting two materials under pressure, do not have to wait for the glue to dry. Use wet bonding method, first place the material at the device, apply glue to the interface of the data, and adjust the position of the two materials correctly. It will bond firmly to the position you designed. 11. Check whether the glue between the glue and the anti-rust paint of the iron pipe is firmly bonded. * Drying time: refers to the time between the application of glue to the bonding of the data. Rubber and plastics determine the thickness of insulation materials: 1. The higher the ambient temperature, the thicker the data; 2. The greater the relative humidity, the thicker the data; 3. The lower the temperature of the medium, the thicker the data.

Rubber and plastic insulation material is the introduction of foreign zui new technology and advanced automatic continuous production line. It uses excellent rubber, polyvinyl chloride (NBR/PVC) as the main raw material, with various high-quality auxiliary materials, and foamed by special process. Made of soft insulation insulation energy-saving materials. The rubber-plastic insulation board is a closed-cell elastic material with excellent properties such as softness, resistance to bending, cold resistance, heat resistance, flame retardancy, water resistance, low thermal conductivity, shock absorption and sound absorption. Can be widely used in central air conditioning, construction, chemical, pharmaceutical, textile, metallurgy, shipbuilding, vehicles, electrical appliances and other industries and departments of various types of hot and cold medium pipelines, containers, can achieve the effect of reducing cold damage and heat loss. Because of its convenient construction, neat appearance and no pollution, it is a high-quality cross-century new generation thermal insulation material. Rubber and plastic insulation pipes are safe to use and will not irritate the skin or harm 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 the gorgeous rubber and plastics an ideal insulation material for protecting pipes from corrosion due to atmospheric media or industrial environments. Rubber and plastic insulation board fire prevention: The national fireproof building materials quality supervision and inspection center tests the flame retardant B1 level, in line with the national standard GB8624-1997 standards. Rubber and plastic insulation board shockproof: the material is PEVA high foaming material,

The insulation board and the pipe are soft and elastic, so as to achieve a good shockproof effect. Rubber and plastic insulation board insulation: has a detailed independent bubble structure, no air convection, thermal conductivity <0. 0325W / MK. Rubber and plastic insulation board sound insulation: with independent and fine air chamber, strong sound insulation, can be used for noise reduction projects. Rubber and plastic insulation board temperature: in the environment of +89 ° C, -60 ° C, can not afford material changes, suitable for cold storage projects. Rubber and plastic insulation board waterproof: the material is PEVA rubber and plastic closed bubble structure, each air chamber is closed. Anti-corrosion of rubber and plastic insulation board: This material is a high molecular polymer, which can completely prevent the corrosion of acid and alkali salts. Rubber and plastic insulation board processing: easy to cut, easy to bond, soft material, flexible, especially convenient for installation. Rubber and plastic insulation has high elasticity, so it can greatly reduce the vibration and resonance of chilled water and hot water pipes during use. At the same time, the rubber and plastic insulation pipe has good winding and toughness. It is easy to handle curved and irregular pipes during construction, and it can save labor and materials. So what are the specific advantages of rubber and plastic insulation? Here is a brief introduction: Rubber and plastic insulation is easy to install and beautiful. Because of the softness of this product, the installation is simple and convenient. Pipe installation: It can be installed after being installed, or the pipe can be cut longitudinally and then bonded with aluminum foil tape. For complex parts such as valves, tees, elbows, etc., 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. Rubber and plastic insulation pipes are safe to use and will not irritate the skin or harm 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. Wide temperature range, good weather resistance, durable and practical, with excellent fire retardant effect.
