Cold storage insulation board is a commonly used engineering construction material. However, it is still unfamiliar to non-professionals. Today Xiao Bian came to introduce you to the cold storage insulation board construction plan and the purchase of knowledge, together to find out about it!
Cold storage insulation board construction plan
Construction preparation:
1. Familiar with drawings, self-examination and review of drawings, and one-off disclosure;
2, the preparation of the construction budget;
3. Clean the construction surface according to the drawings, and set the processing site and temporary storage in the local area. If it cannot be set at the construction site, set it outside the construction site;
4. Temporary housing for construction workers and on-site temporary warehouses shall be coordinated and resolved according to site conditions;
5. Organize engineering and technical personnel and construction team leaders, and be familiar with plans, understand and master design intent, and make technical disclosures;
6. The implementation of cross-connection and coordination work of the construction unit organized by Party A in civil works and cold storage;
7. According to Party A's determination of the construction drawings and construction schedule, the preparation of the main material plan, semi-finished product processing application form and order details.
The warehouse thermal insulation project specially formulated the following construction plan:
1. Use 107 glue and cement to prepare paste and paste polyethylene-polypropylene cloth. Firstly, clean the walls, floors, pillars and beams. Wherever you need to paste the gas barrier, remove the protruding particles and lumps. , remove dust and clean. Then brush the slurry, then paste the polypropylene cloth, overlap 8 ~ 10cm.
2, in the dry curing outside the gas barrier layer coating - layer thickness of 3 ~ 5mm thick paste paste, and paste extruded insulation board, different temperature insulation paste different thickness of the insulation board, and paste the paste. Separate columns for refrigerators and freezers are reinforced with special insulation nails, in accordance with the requirements of the contract.
3. Lay out and paint the anti-cracking mortar on the outer layer of the heat-insulating board. Lay 300 g grid cloth, request the lap joint to overlap 3~5cm, and use the #16 wire to make the saddle nail fixed, and then connect and fix with special insulation nail. firm.
4, in the laying of a good grid, and then painted anti-crack mortar, to be basically dry after the third surface coating anti-crack mortar, so that the appearance of smooth, and calendered, the total thickness of 7 ~ 10mm.
5. In each of the above processes, construction records must be prepared and accepted by Party A and the supervisor before proceeding with the next operation. In order to improve, beautiful, meet the requirements of the contract.
Cold storage insulation board to buy common sense
1, insulation performance
The first requirement of cold store thermal insulation material is its thermal insulation performance. These thermal insulation properties cannot be identified by our own eyes. Therefore, we must choose the insulation materials produced by those regular manufacturers. This kind of manufacturer has strict quality control in both material selection and production.
2, dimensional stability
Polyurethane foams in cold storages will change in size (usually shrinkage) when the temperature changes violently or at a relatively low temperature for a long period of time. Size change often manifests as foam cracking or shedding, and these will inevitably affect the normal use of cold storage.
3, service life
In addition to the basic properties of the cold storage insulation board, its service life is also very important. In the preparation of white materials, these polyester materials use foam on the surface with good toughness and impact resistance. After you use it in the cold storage for a while, he will become very brittle, which will reduce the life of the insulation board. Therefore, although it is slightly brittle in the initial stage, brittleness generally disappears after a few days, and the performance of the insulation material of the cold storage is maintained for a long period of time.
Xiao Bian concludes: About the cold storage insulation board construction plan and purchase of common sense is introduced here, I hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
