Friends, aluminum foil butyl tape is a self-adhesive waterproof sealing tape made of butyl rubber as the main raw material, with other additives, aluminum foil as the base film, and processed by advanced technology. It has extremely strong adhesive force, at the same time, it has excellent weather resistance, aging resistance and water resistance, and plays the role of sealing, shock absorption and protection on the surface of the adherend. The product is completely solvent-free, so it does not shrink or emit toxic gases. It is an extremely advanced environmentally friendly waterproof sealing material. It is suitable for roof waterproofing, underground waterproofing, waterproofing treatment of structural construction joints and lap sealing of polymer waterproofing membranes in construction projects; sealing and waterproofing of construction joints in subway tunnel structures in municipal engineering; Sealing, waterproofing, shock absorption; airtightness, waterproofing, shock absorption at the joints in the solar panel project; bonding and sealing treatment in automobile assembly; waterproofing and sealing treatment at the meeting place in steel structure construction; butyl tape with composite aluminum foil It is suitable for waterproof sealing of various civil roofs, color steel, steel structure, waterproof coiled material, PC board, etc. under sunlight.
Aluminum foil butyl tape is a pressure-sensitive aluminum foil sealing tape made by aluminum foil and butyl rubber adhesive through advanced production technology. The product has good adhesion and sealing performance for various metal materials and non-metal materials. It has excellent weather resistance, aging resistance and chemical resistance, and has the functions of sealing, shock absorption and protection on the surface of the adherend. The product does not contain organic solvents, has strong stickiness, and does not solidify for life. It can follow the expansion and contraction of the surface of the adherend and the deformation caused by external force. It is an environmentally friendly waterproof sealing material with excellent performance. Before use, it is necessary to remove impurities such as water, oil, dirt, dust, etc. and the silicone adhesive on the adhered surface before repair. In special cases, it can be cleaned with organic solvents. It is necessary to wait for the adhered surface to dry completely before construction. Remove the release paper from the tape and apply the tape along the seams or cracks. Use your hand or a small pressure stick to roll the surface of the tape to make it fully adhere to the surface to be adhered.
The thickness of the aluminum foil butyl tape is relatively uniform, and the adhesion between the substrate and the adhesive layer is also relatively large. To avoid degumming and other phenomena during use, let me talk about its winding method today. Let's take a look:
(1) Remove the rust, welds and burrs on the surface of the pipeline. After removing the rust, the attachments on the surface of the pipeline should be cleaned and the surface of the pipeline should be kept dry.
(2) The primer should be applied within 6 hours of pre-treatment on the surface of the pipeline. If the time is too long, or overnight, or if the surface is dusty, the steel pipe should be treated again. The primer should be stirred evenly in the container before painting. When thickened, the thinner matched with the primer should be added, and the construction can only be carried out when it is diluted to a suitable viscosity.
(3) The primer can be sprayed with a clean brush, roller or some other mechanical method. When the primer is dry, the aluminum foil butyl tape can be wrapped around 2-3 minutes, and the interval between the surface of the pipe and the tape should be controlled within 8 hours.
(4) When winding aluminum foil butyl tape, the tape edge seam should be parallel, without twisting and wrinkling, and a certain tension should be maintained to make the tape layer tightly connected.
Aluminum foil butyl tape has a good effect of reflecting ultraviolet rays and can play the role of anti-corrosion insulation. When using tape construction, why there are wrinkles when winding?
1. The thickness of the pressure roller adhesive layer of the construction pipeline is too thin. After deformation, the roller core directly contacts the anti-corrosion layer, which will cause wrinkling of the aluminum foil butyl tape.
2. The rotation of the pressing roller is stalled, or the jitter causes the anticorrosion layer of the aluminum foil butyl tape to rub and form a wrinkle.
3. During the tape molding process, no matter what method is used for winding, there is an air layer between the intermediate adhesive and the surface of the pipeline. This air layer is expelled during construction, otherwise an air film will be formed between the surface of the steel pipe and the anticorrosion layer, which is likely to cause tape formation Wrinkled.
