Any one long edge of two cement boards of every group is in the same place, and wherein a cement board is as fixed cement board, and another cement board is as removing the cement board, removes along the direction on the long edge of perpendicular to when removing the cement board and removes to guarantee that monoblock cement board carries out synchronous motion.
(2) And respectively arranging a comparative example 1, a comparative example 2, a comparative example 3 and a comparative example 4 on four groups of cement boards which are attached together, coating a paint layer outside the putty layer after the putty layer is dried completely, and standing for 48 hours to ensure that the paint layer is dried completely.
(3) And respectively moving the movable cement boards in the four groups of cement boards, observing the states of the putty layer and the paint layer when the distance between the movable cement boards and the fixed cement boards is 0.05CM, 0.1CM, 0.15CM, 0.2CM, 0.25CM, 0.3CM, 0.4CM, 0.5CM and 0.7CM, and recording to form the following table 1.
TABLE 1
As shown in Table 1, compared with the putty layer formed by coating the existing putty paste, the putty layer disclosed by the invention has an obvious anti-cracking effect, can effectively avoid cracking of the putty layer when a crack of a wall is small, and better avoids the influence on the attractiveness of the wall due to the cracking of a paint layer.
During the experiment, can set up and bear the base for bear the cement board that sets up in groups. Bear and set up two sets of clamping structure on the base, a set of clamping structure is two wide edges of fixed cement slab for fixed clamping structure centre gripping, another group of clamping structure is two wide edges of removal clamping structure centre gripping removal cement slab, fixed clamping structure is fixed motionless, the clamping structure that the centre gripping removed the cement slab then can remove to the direction of keeping away from fixed clamping structure, set up the scale on bearing the base, in order to read the displacement distance that removes clamping structure, this displacement distance is interval between two cement slabs promptly.
When preparing the experiment, fix two block cement boards in groups respectively on clamping structure earlier, then control clamping structure is close to and makes two block cement boards laminate each other, paints putty layer jointly on two block cement boards after that to paint the oil paint layer after putty layer is dry, has made the experiment preparation promptly after waiting for the paint layer drying.
During the experiment, the movable cement board is controlled to be clamped by the movable clamping structure to move towards the side away from the fixed cement board, the movable cement board stops moving when moving to a corresponding distance, the distance is kept for standing, the states of the putty layer and the paint layer are observed and recorded after standing for 24 hours, and the process is repeated until the paint layer cracks if the paint layer does not crack.
Experimental example 2
The difference between this example and example 1 is that the putty layer was applied in the manner of example 14 and is labeled as comparative example 1 ', comparative example 2', comparative example 3 'and comparative example 4'. The putty layer and the paint layer were observed and recorded to form table 2 below.
TABLE 2
As shown in Table 2, compared with the putty layer formed by coating the existing putty paste, the putty layer disclosed by the invention has an obvious anti-cracking effect, can effectively avoid cracking of the putty layer when a crack of a wall is small, and better avoids the influence on the attractiveness of the wall due to the cracking of a paint layer.
The combination and analysis of tables 1 and 2 show that the crack resistance of the putty layer can be further improved by arranging the crack resistance layer and the plane adhesion layer at intervals.
In addition, the above-described embodiments are exemplary, and those skilled in the art can devise various solutions in light of the present disclosure which are within the scope of the present disclosure and are within the scope of the present disclosure.
