What are the advantages of polyurethane cold storage boards

Polyurethane cold storage board with lightweight polyurethane as the inner material of the cold storage board, the advantage of polyurethane is that the thermal insulation performance is very good, the outside of the polyurethane cold storage board is made of SII, PVC color steel plate and stainless steel plate components, the advantage of this is to prevent the cold storage board from spreading the temperature due to the large temperature difference between inside and outside, so as to make the cold storage more energy-saving, improve the work efficiency of the cold storage.

The polyurethane cold storage board is illustrated in the figure below.

1. Rigid polyurethane has low thermal conductivity and good thermal performance. When the twilight capacity of rigid polyurethane is 35 40kg m3, the thermal conductivity is only about half of EPS, which is the lowest thermal conductivity among all insulation materials.

2. Polyurethane cold storage board has moisture-proof and waterproof performance. The closed cell rate of rigid polyurethane is more than 90%, which is a hydrophobic material, and will not increase the thermal conductivity due to moisture absorption, and the wall will not seep water.

3. Polyurethane cold storage board is fireproof, flame retardant and high temperature resistant. Polyurethane is a flame-retardant, self-extinguishing material with a flame retardant that can soften at more than 250 degrees Celsius and only decomposes at higher temperatures: in addition, when burned, polyurethane forms ash on the surface of its foam, which helps to isolate the foam underneath.

It can effectively prevent the spread of fire. In addition, polyurethane does not produce harmful gases at high temperatures.

4. Because the polyurethane sheet has excellent thermal insulation performance, it can reduce the thickness of the building envelope structure and increase the indoor usable area under the same thermal insulation requirements.

5. Strong anti-deformation ability, not easy to crack, stable and safe finish.

6. The porosity structure of polyurethane material is stable, basically closed-cell structure, which not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. The average life of rigid foam polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions. It can be achieved under normal conditions of use during the life of the structure, in dry, wet or galvanic corrosion, and because insects, fungi or algae foam has a higher unit price than other traditional insulation materials, but the increased costs will be offset by a significant reduction in heating and cooling costs.

7. There are many specifications and varieties, and the bulk density range: (40-60kg m3); Length range: (m-4m); Width range: (m-m); Thickness range: (20 mm - 200 mm).

8. The cutting accuracy is high and the thickness error is correct, so as to ensure the flatness of the surface of the finished product.

9. Convenient quality inspection, because the surrounding skin is removed during the cutting process, the quality of the plate is clear at a glance, which ensures the thermal insulation effect of the finished product. The thickness can be produced and processed according to the user's requirements [1].

The answer cites the encyclopedia.

Polyurethane cold storage board is the core material of cold storage, which is characterized by low thermal conductivity, high bending strength, no water absorption, no decay, and a large temperature resistance range, which can block the spread of heat to the greatest extent and make the cold storage more energy-saving. And with the reform of manufacturing technology, the manufacturing efficiency of polyurethane cold storage board has become very efficient, all of which are advanced automated continuous production equipment, and the production process is automatically controlled by computer, which makes the cost of polyurethane cold storage board not high, easy to install in a large area. Let Xiaotu introduce the construction plan of the polyurethane cold storage board to you.

Construction preparation and precautions:

1.Check whether the construction requirements are met before construction, and the construction can only be carried out after the construction requirements are met.

2.The construction sequence is strictly in accordance with the order of the ceiling, then the wall, and then the ground to prevent damage to the ground insulation layer.

Hall Raid 3Strictly control the ratio of materials to 1:1 or, the thickness of the insulation layer should be sprayed in layers according to the construction requirements.

4.For each process, it is necessary to make a good construction record, and the two parties of the construction cooperation will jointly accept the operation of the next process.

Construction Method:

1.Wall board installation: use 107 glue and cement to prepare and paste paste, paste polyethylene polypropylene cloth, first clean the wall, ground, and columns, pay attention to all the places that need to be pasted with the air insulation wide layer must be thoroughly cleaned, remove protruding particles and blocks, sweep away dust, and clean up.

2.Coating slurry: After the installation of the wall board, at the same time lap 8-10cm polypropylene cloth, scrape and coat the paste mortar with a thickness of 3-5mm thick outside the dry and cured air insulation layer, and paste the extruded insulation board, paste the insulation board of different thickness to the cold storage at different temperatures, and paste the staggered seams, pay attention to the uniform coating of a layer of slurry first, and then paste the polypropylene cloth.

3.Reinforcement: The columns of the cold storage and freezing storage are reinforced with special insulation nails, which are specifically done in accordance with the requirements of the construction regulations.

4.Laying mesh cloth: After brushing the outer layer of the insulation board and painting the anti-cracking mortar, lay 300 grams of mesh cloth, which requires 3-5cm lap at the lap joint, and is fixed with 16 iron wires made into riding nails, and then connected and fixed firmly with special nails for thermal insulation.

5.Painting: In addition to the laid mesh cloth, the anti-cracking mortar is painted, and the third surface layer is painted with anti-cracking mortar after it is basically dry, so that the appearance is smooth and calendered, and the total thickness reaches 7-10mm.

In this way, the construction of polyurethane cold storage board is basically completed, generally speaking, the quality of polyurethane cold storage board is light, the thickness is small, and the style can be changed freely, so the quality inspection is very convenient, but the rabbit wants to remind everyone that although the construction project of polyurethane cold storage board is not complicated, but each step must be strictly implemented in accordance with the requirements, can not be negligent, the completion of the project is the result of group cooperation, so in the construction process, the construction personnel should cooperate with the construction, coordination, For the equipment installed on the site, it is necessary to handle it with care and protect the construction site.
