1. Construction Regulations for Barbed Carpets
(l) Construction procedures: Barbed strips are the main method of roll carpet pavement and an important item in high-end home decoration. The standard procedure of carpet barbed pavement is: grassroots cleaning treatment →Carpet cutting→Nail barb board→Padding layer→Seam→Zhang Ping→Fixed carpet→Edge trimming→Repair carpet surface→Cleaning. The quality of carpet pavement is very important for the evaluation of the quality of home decoration In order to ensure the construction quality, construction must be carried out in strict accordance with the prescribed procedures.
(2) Technical essentials: Carpet pavement has high requirements for the ground of the base layer.The ground must be flat and clean, the moisture content should not be greater than 8%, and the skirting board has been installed.The gap from the bottom edge of the skirting board to the ground should be 2~3 greater than the thickness of the carpet Mm. The seam is an important process that affects the pavement roll carpet. The direction of the warp should be indicated on the back of the carpet before the seam to avoid the pile down at the seam. Pure wool carpets are generally stitched with needles. Align, brush the carpet glue, seam paper after the seam is strong, and the chemical fiber carpet with sackcloth backing is generally glued with carpet. Repair of the seam is very important, you must first repair the uneven fluff of the seam, And repeatedly rub the fluff at the seam until the seam traces are not visible on the surface. The flattener is a key process related to carpet pavement, and the carpet tensioner (commonly known as the brace) should be used for the operation. The method of using the tensioner is First put the corner of the short side of the carpet into the gap under the skirting board with a flat shovel, and then use the brace to flatten the short side, insert the entire short side into the gap under the skirting board, fix it to the barb board, and then support the brace Withstand the wall at the fixed end, grab the other end of the carpet with the pick teeth, and stretch the carpet flatly by the lever of the brace. Use the brace to pay attention to the moderate tension, too much strength can easily tear the carpet, too When the carpet is fixed, the carpet is hung on the barb board, and it needs to be lightly tapped to ensure that all the barbs hook the carpet and avoid the carpet from loosening due to the incorrect hook.China Wholesale Rug Mat Yarn Factory
2. Construction specification for fixed-bonded paving carpet
(1) Construction procedures: fixed bonding is an important method for laying carpets, and its standard procedures are: ground treatment at the base level → actual pay-off → cutting the carpet → scraping the glue to dry → laying silver pressure → cleaning. fixed bonded carpet Although the technical requirements are lower than the requirements of the barbed plate, they also need to be constructed according to standard procedures.
(2)Technical essentials: Rooms with bonded carpets are often unsettling skirting boards. If installed, it is also installed after ￥E carpet pavement. The carpet and the wall root are directly bordered. Therefore, the carpet cutting must be very accurate, before paving. The actual quantity must be measured to determine whether the corners of the wall are square and accurately record the angles of the corners. When cutting the carpet, you should cut along the carpet warp yarn, only cut the weft yarn, not the warp yarn.For the backed carpet, you should separate the fluff from the front to find out Warp and weft yarns are cut after cutting. Carpet scraping glue should use a special V-shaped tooth trowel to ensure that the glue is spread evenly. The order of scraping is to start at the seam position and then scrape the edge. The time for air-drying after scraping the glue It is very important, generally it should be left to air for 5~10 minutes, the specific time depends on the type of glue, the compactness of the ground and the environmental conditions, and it is best to install it when it is dry and sticky when touching the surface. At the beginning, expand to both sides, and when no stitching is needed, pave from the middle to the periphery. When paving, use a brace to straighten the carpet from the middle to the wall, and immediately use a felt reel to compact it after paving.
3. Acceptance of carpet pavement
No matter what kind of carpet pavement method is used, the surface of the carpet must be smooth and clean after paving, no slack, bulging, skirt wrinkles, edge curling, etc. F joints should be firm and tight, without seams, without obvious stubble, No velvet, consistent color and gloss, no wrong flowers, wrong grids; the door and other closings should be straight and tight, the bottom edge of the skirting board is tight, the sealing is smooth. The quality of the carpet pavement should be reworked.
4. Common quality problems and treatment methods of carpet pavement
Common quality defects in carpet pavement include bulging, skirt wrinkles, inconsistent color and loose carpet.
(1) Drums and creases: In addition to the carpets not being flattened before paving, the main reason is the unevenness of the stretch of the support during the paving and the individual barbs in the barb board not caught. When opening, there will be a bulging phenomenon, and the carpet should be rolled back and flattened. The support of the support should be even when paving. After Zhang Ping, immediately install the barb board and hit with a flat shovel to ensure that all barbs can be Grab the carpet.
(2) Inconsistent color: the reason is that in addition to the poor quality of the material, it also includes that the surface of the base layer is wet or seeps to make the carpet discolor after absorbing water, and sun exposure makes the surface of the carpet lighter. It is necessary to choose good quality and color when buying Consistent carpets. Avoid using carpets on the water and grounds that are prone to water. Do not install carpets. Avoid direct sunlight or construction in harmful gas environments. Avoid direct sunlight in daily use.
(3) Loose carpet displacement: The main reason is that the barbs on the barb board cannot be fixed. Should the barb board be configured as required?
5. Estimated construction period of carpet pavement
Carpet pavement is a project with high comprehensive technical requirements, and more than two people must cooperate in the operation. If it is a carpet pavement with cushions, under the condition that the base layer is well processed, two people can complete a room in a day, such as Without padding, the construction period can be shortened by 1/3. Carpet pavement requires continuous operation in a room, which can be solved at one time. It can be solved by increasing labor. Different types of carpets use different pavement methods, and the construction period will be different. Installation work cannot be cross-operated with other types of work.
