Description

Technical Field

[0001] The utility model relates to the technical field of clean rooms, in particular to a waterproof machine-made board for a clean room and a clean room. Background Art

[0002] At present, in clean rooms such as food clean factory workshops, most of the ceiling and wall panels are made of machine-made panels. However, once the clean room has a pipe leak or the indoor humidity is very high, a large amount of condensation will appear on the panel surface, and the cuts around the machine-made panel will be flooded or even rusted. Generally, after 1-2 years, the panel surface will show large-scale corrosion, and the later maintenance cost will also be high.

[0003] In the related technical scheme, only glue is applied on the side of the machine-made board. After long-term use, gaps are easily formed at the sealant position due to thermal expansion and contraction, etc., and it is impossible to achieve sealing protection for the incisions around the machine-made board and even the core board. Utility Model Content

[0004] The utility model provides a waterproof machine-made plate for a clean room and a clean room, which can solve at least one of the above technical problems.

[0005] In order to solve the above-mentioned technical problems, one or more embodiments of the utility model provide a waterproof machine-made panel for a clean room, comprising a square core board, wherein two sides of the core board perpendicular to its own thickness direction are respectively bonded with a panel, and the panel has two sides along its own length direction and two sides along its own width direction.

[0006] The outer side of the panel facing away from the core board has a 50μm thick sprayed plastic layer; the two sides of the core board along the perpendicular width direction are respectively concave in the panel to form an embedded space, and the embedded space is embedded with a keel, the outer surface of the keel has a 0.6mm color coating, and the two sections of the keel perpendicular to the length direction of the core board have a 20μm anti-corrosion coating. The section of the panel perpendicular to the length direction of the core board has a water-based anti-rust paint layer, and the interface of the panel, core board and keel is provided with a hot melt adhesive layer, which extends along the length direction of the panel and is equal to the length of the panel; the two sides of the core board perpendicular to its own length are respectively provided with a tape layer, and the two ends of the tape layer are respectively bonded to the two panels, and the tape layer spans the laminated core board, and the width of the tape layer along the width direction of the core board is at least 15mm towards the center of the core board.

[0007] One or more embodiments of the utility model further provide a clean room, comprising a wall base and the above-mentioned waterproof machine-made board for a clean room; the wall base is a sill wall with a ceramic tile layer on the outer surface, a groove is provided in the wall base, and one end of the machine-made board is inserted into the groove. The thickness of the groove is 60 mm, the thickness of the machine-made board is 50 mm, and structural adhesive is filled between the inner wall of the groove and the machine-made board.

[0008] The beneficial effects of one or more of the above technical solutions are:

[0009] (1) In this scheme, the surface of the panel is provided with a spray coating, and the section of the panel perpendicular to the length direction of the core board is provided with a water-based anti-rust paint layer; at the same time, the outer surface of the keel has a color coating, and the two sections of the keel perpendicular to the length direction of the core board have an anti-corrosion coating. This setting method protects the panel and keel at the outer contour of the entire machine-made board with corresponding coatings, thereby avoiding the probability of water accumulated on the panel surface leaking and corroding the outer contour of the machine-made board, and prolonging the rust time of the entire machine-made board.

[0010] (2) The keel is sealed with a hot melt adhesive layer at the contact point with the board surface and the core board to prevent water vapor from entering the core board from the interface between the three; the section (i.e., cross section) of the clean board perpendicular to the length direction of the core board is sealed with a tape layer, and the width of the tape layer from both ends along the width direction of the core board toward the center of the core board is at least 15 mm, which can avoid the core material from being exposed at both ends along the width direction and reduce the probability of water vapor entering the board from both ends of the core board cross section along the width direction, causing the core material to absorb water.

[0011] (3) In the connection structure between the machine-made clean board and the wall foundation, this scheme uses a groove with a thickness greater than that of the machine-made board and fills it tightly with structural adhesive to prevent external moisture from contacting the cross section and avoid rust and corrosion.
