Analysis on the construction requirements of clean board in hospital operating room purification project
Release time:2019-12-27 source:
As we all know, every detail of hospital operating room purification project has extremely strict and high-level requirements from the beginning of design to formal construction. Mainly because in the process of operation, every tiny detail may be related to the health and safety of all medical staff and patients. Of course, even the walls and floors in the operating room purification project of the medical cleaning engineering company are no exception.
So, in the process of design and construction of the wall and ground of the hospital operating room purification project, what are the detailed requirements? Let's take a look at how to construct the clean board of the hospital operating room purification project:
1、 Wall leveling of hospital operating room purification project
According to the datum point of the wall, the plastering leveling and alignment are carried out. Compared with the common base plastering, the watering and moistening process of the wall is reduced. The mortar is mixed with a certain proportion of binder, and the construction can be carried out as long as the dust and sundries on the wall are cleaned up. The mortar can be scraped flat with a 2m guiding rule and should not be calendered. The allowable deviation of the wall is: the surface flatness deviation is ± 2mm, the vertical deviation of the facade is ± 2mm, and the vertical deviation of the internal and external corners is ± 2mm.
2、 Wall division and setting out of purification engineering in hospital operating room
According to the detailed drawing of plate arrangement and division, the division line shall be marked out, and the horizontal and vertical gap between the clean plate and the plate shall be reserved, so that the line snapping of the base wall surface is clear, horizontal and vertical.
3、 Hospital operating room purification engineering cutting clean board
According to the actual size of the field grid, provide the specific cutting size of the clean board. The cutting of the clean board can be done by professional personnel in the factory or on the site. The cut clean board shall have neat edges and corners, diagonal deviation less than 2mm, complete coating, no bulge and scratch.
4、 Application of glue on the board of purification engineering in the operating room of the hospital
1. Clean the dirt and dust on the bonding surface of the board to ensure there is no oil, water and dust.
2. Brush at least two times of organosilicon waterproof agent on the section of the decorative board with a brush.
3. After the surface of silicone waterproof agent is dry, paste PE double-sided tape around the back of the clean board, and add two PE double-sided tapes at the middle part of the short side to ensure the firmness of the bonding.
4. After pasting the double-sided adhesive, evenly apply the construction structural adhesive to the middle part of the back of the clean board according to the point sticking method. The thickness of building structural adhesive shall exceed the thickness of PE double-sided adhesive strip, generally not less than 6mm.
5、 Paste clean board in hospital operating room purification project
1. The installation of the clean board shall be pasted from bottom to top, first from the external corner to the internal corner.
2. Remove the film covering on the other side of the double-sided adhesive tape, paste the clean board on the wall according to the position of the grid line, generally use the line pressing construction, and control the flatness within 2mm (check with a 2m guiding rule).
3. The wooden keel (9cm board small piece or slat) is temporarily used between the two clean boards to fix the two boards, so that the board surface is fully pasted with the wall surface, and is removed after the building structural adhesive solidifies.
6、 Hospital operating room purification project overall inspection
The overall flatness, perpendicularity, seam size and evenness of the clean board surface shall be checked after the completion of each section of the installation. If necessary, appropriate adjustments shall be made to achieve satisfactory results before the next step of installation.
7、 Treatment of slab joint in purification engineering of hospital operating room
1. After all the clean boards are pasted, the overall quality and effect of the construction shall be checked thoroughly again, and appropriate adjustment shall be made if necessary. After the satisfactory effect is achieved, the wooden keel (nine millimeter board) for temporary fixation shall be removed.
2. According to the size of the slab joint, select the appropriate caulking strip to fill the slab joint. The depth of the joint strip and the board surface shall be 3-5mm.
3. Stick masking paper (paper tape) along the seam line of the board according to the requirements of the grid width to prevent pollution of the board surface, and then brush the section of the decorative board with a brush for at least two times with silicone waterproof agent.
4. After the surface of organosilicon waterproof agent is dry, apply sealant evenly and appropriately in the board joint with sealant gun, and then use a flat scraper to scrape the sealant. The thickness of sealant on the board is required to be 0.5-1mm. Pull off the paper tape after sizing.
8、 Plate cleaning of purification engineering in hospital operating room
Clean the dust and dirt on the edge of the clean board first, and then tear off the protective film. Special care shall be taken to clean the dirt on the surface of the clean board. It is not allowed to scrub vigorously or scrape with sharp tools such as blades. Only solvent and water can be used for cleaning.
After the construction of the clean board is completed, the construction site shall be cleaned after the joint sealant is solidified. All the remaining materials shall be recycled and stored by category. After the site garbage is thoroughly cleaned and properly packed, it shall be transported to the designated dustbin or garbage centralized treatment center.
The professional technicians of ED operating room purification engineering design a reasonable scheme to adapt to the production process and project cost, the design technical indicators meet the national standard of clean room, the experienced operating room purification engineering construction team is fast and efficient, and the after-sales service is perfect.
