Characteristics of Ceramic Tile Adhesive and Construction Improvement Method
Ceramic Tile Adhesive Product Characteristics
1. The composition of ceramic tile adhesive
Ceramic tile binder using high-quality inorganic cementitious materials, fine aggregates, Portland cement, a small amount of hydrated lime and according to product quality level requirements added functional additive composition. The bonding performance is significantly higher than the traditional cement.
Tile glue is divided into two main categories, one kind is the cement as the base of the dry powder products, the other is a good mix of organic rubber products, followed by two-part and solution-type additives and the gap for the caulking agent.
Cement as the base of the ceramic tile adhesive: This kind of product from cement, fine sand, and poly in a certain proportion of mixed with dry powder products.
(1) on-site construction and mixed with water can be pasted;
(2) can be used for indoor and outdoor wall floor;
(3) Good water resistance can be used for long-term immersion pool, swimming pool;
(4) only applies to the cement base and the brick wall structure does not apply to the gypsum board, the plank and may cause the distortion, the concussion the substrate.
Organic Adhesive Tile Adhesives: These products are mainly acrylic products, some are PVA or rubber latex products, to be the point:
(1) Ready-mix can be used;
(2) Good flexibility can be used for gypsum board, fiberboard, composite board, wood substrate on the top;
(3) Water resistance is slightly poor, can not be used for long-term immersion in the pool;
(4) Not suitable for outdoor, white plastic products are not suitable for the floor.
2. The physical properties of ceramic tile adhesive Advantages
(1) strong adhesion, strong, to avoid the occurrence of empty drums or shedding phenomenon;
(2) The construction of brick wet wall can obviously improve work efficiency, convenient and fast;
(3) Good impermeability and anti-aging properties;
(4) has the elasticity, may absorb the bottom material and the tile the expansion contraction, effectively prevents the ceramic tile crack to produce, thus lengthens the ceramic tile service life;
(5) with good water resistance, temperature resistance, waterproof impermeability, freeze-thaw, cold and hot and rapid degeneration, can prevent empty drums and cracks. Simple operation, convenient construction, high efficiency, good water retention and high adhesive strength.
3. Type of tile glue and application range
There are many brands of tile glue in the market, each brand is divided into many models, performance and price vary. As a result of ceramic tile manufacturers, many, mixed, product quality and price is also a big difference.
Construction Technology of tile glue
1. Tile adhesive thin Paste method
Thin Paste method is a new type of pasting ceramic tile technology, with special ceramic tile adhesives and toothed scraper, on the construction base surface to scrape the tile binder comb into stripes, and then in order to paste the tiles on the mortar, the use of kneading and compaction of the real location of the dry job pasting method. Its characteristics are, unit adhesive dosage Small, thin coating, sticky relay strong, quality assurance, grass-roots, no need to bubble bricks, construction speed, environmental protection.
2. Standard practice for Ceramic tile Adhesives
Base surface requirements
(1) Base surface should be flat, clean, strong, no dust, grease and other dirt and another loose;
(2) The base surface roughness should be checked by 2 meters, the flatness is less than 5mm, the verticality is less than the 4mm.
Electric Stirrer (can be the 750~1000w portable electric drill, with the spiral stirring stick), sturdy plastic bucket, toothed scraper, ceramic tile cutter, horizontal ruler, Cross glue granule, etc.
(1) Bullet line positioning
To determine the ground elevation and the plane position line, or to the wall surface to play a good horizontal control line, do a bottom support straight.
(2) mixing and mixing
For the new batch of cement mortar base surface, first, pour water into the container, and then put the tile glue into the container, according to the standard gouache ratio to stir until the appropriate consistency.
According to the proportion, in order the water → additive → tile glue into the container, and stirring at the same time to stir to the appropriate consistency. Can be stirred by hand or mechanically until the powder is free. After mixing, you need to sit for 5 minutes, then stir and then use.
(3) Scraping paste Paving
With the tooth-shaped scraper will be coated with rubber paste and face, so that the uniform distribution, every time the figure scraping about 1 square, can be controlled by the tilt angle of the tooth scraper to adjust the thickness of the mortar, generally 45 degrees tilt.
Use from down to top (wall order), from the inside to the outside or the middle to the surrounding (ground order), the tile (or stone plate) knead on the face can be.
The use of cross cards to ensure that the vertical, flat, joint size uniformity; the construction process should be used to check the smoothness of the horizontal ruler or ruler, and make adjustments.
(1) It is strictly prohibited to add sand, cement, and other additives.
(2) Ceramic tile adhesive should be mixed with the use, mixing good tile adhesive should be used up within 4 hours, has solidified hardened mortar is not allowed to reuse, and should not be dry of the mortar and water mixed reuse.
(3) The firmness, verticality, and flatness of the base surface should be confirmed before construction.
(4) After the tile paste, because the dislocation needs adjustment, must adjust within the adjustment time, lest affect the intensity.
(5) The construction process of the extra tile glue should be removed before hardening.
(6) Check the glue layer on the back of tiles in time to ensure that there is no empty drum phenomenon, or it should be filled in time.
(7) After the completion of the construction 24 hours, the party may step into or fill the seam.
(8) This product is suitable for use in 5~40℃ environment.
Ceramic tile Adhesive Improved method
Ceramic tile standard practice, Tile glue construction thickness is relatively thin, about 6mm, more than the traditional process to save materials, reduce costs, but on the panel surface smoothness and verticality requirements, and the current Division I panel body Quality control effect can not fully meet the requirements. In order to ensure the construction efficiency and construction efficiency, and the traditional bonding process to adopt a combination of methods, ceramic tile standard practice to improve, as follows:
1, the use of ceramic tile glue instead of cement, the tile glue and water in proportion to mix, and stir to even;
2, use the cement shovel to scrape the tile glue evenly on the back of the wall brick;
3. According to the wall brick line in advance, the tile glue will be pasted on the wall, and the movable knock is real;
4, the use of aluminum alloy ruler to check, such as verticality and flatness to meet the requirements of the fixed, if not meet the requirements of the tiles removed ceramic tile glue and then paste.
Ceramic tile adhesive As a wall brick bonding material construction technology has been very mature, the process to reduce the wall brick empty drum obviously played a good role, and has been widely used in various types of buildings. In the application of tile glue construction technology in the field project management, we must soberly realize, reduce, even eliminate the wall brick hollowing off and so on quality common problems, management must first be established in strict compliance with all types of norms and conduct on the basis, and in situ construction efforts to implement the implementation, but not entirely dependent on the replacement of materials or technology changes, after all, any improvement in the construction process can not replace the necessary project management measures.
