Floor heating solid wood composite floor moisture-proof measures

Today's buildings from the comfort, energy saving, environmental protection, health care and space saving five advantages of the floor heating design scheme. Below is the floor heating on the solid wood composite floor, the floor below the moisture-proof film layer, a month after heating found that the surface of carbon black color, carbon black color edge whether it is semicircular, oval, or strip edge is very neat rare phenomenon. After 20 days of continuous observation, the number of locally colored carbon black plates increased from two or three to seven or eight, but its edges are still very neat rare phenomenon cases. The following three photos are for professional manufacturers to discuss and study, and the peers to serve as a warning.

After the manufacturer of the floor construction came to the site to inspect, they said that they had not found this problem before. I have consulted with Beijing decorative floor heating manufacturers warm Cube, Jia Jinyu and other responsible persons and experts of the floor heating Association, they also said that they have not encountered this problem. After preliminary investigation and research, the reasons are as follows:

(1) The paint-free back cover of the 11-layer solid wood flooring is uneven and of poor quality, so that the carbon black edge is neat. The control and test methods of the manufacturer's products before leaving the factory should be implemented in accordance with the GB/ T15036.2-2001 specification, and the composite standard requirements. The floor should be boiled in hot water at 100 ° C for 4 hours, then baked in an oven at more than 60 ° C for 20 hours, boiled in hot water at more than 100 ° C for 3 hours, and frozen at minus 20 ° C for 2 hours. The above procedure is repeated four times to ensure that the floor does not change color in the heat change. The manufacturer did not provide the test report in accordance with the WB/ T15036.2-2001 standard in time, so the material defect of the solid wood composite floor is the main contradiction.

(2) The moisture-proof film under the floor is not glued with 60mm tape or the moisture-proof film is damaged, and the hot air with water vapor directly contacts the solid wood composite floor from the gap, resulting in a blackish color like carbon.

(3) The concrete protective layer above the floor heating PP-R pipe is locally too thin, and the hot gas with water vapor after heating is directly in contact with the floor, and after a few days, the blackened solid wood composite floor is gradually reflected in the color like carbon.

(4) The floor heating of the 3-story sun shed floor was constructed in late September 2014, the moisture in the concrete has not been excluded, and the drying degree of the concrete has not reached the requirement of less than 20%.

According to Article 5.5 of the WB/ T1017-2002 acceptance Code, the blue (black) is calculated according to the area, and each piece ≤10% should be replaced. Total number of blocks ≤5% black or mildew should be replaced. The flange area ≤0.25mm should be replaced. In order to meet the requirements of the perceived quality, the contractor promises to re-enter the qualified solid wood composite floor from the manufacturer again, so that the color difference of the sunlight floor floor proposed at the time of acceptance is too large, complete replacement, rework and re-installation, and no future trouble.
