Core characteristics
1. Reliable application performance
-
(1) Waterproofness
Butyl tape has excellent waterproof performance and can effectively prevent moisture penetration and ensure the dryness of the adherend surface. This feature makes it an ideal choice for waterproofing in the fields of construction, automobiles, etc.
-
(2) Sealing
Butyl tape has good sealing performance and can fill gaps to prevent the penetration of air, moisture and other media. In occasions such as building joints and roof leaks, butyl tape can provide reliable sealing effects.
-
(3) High and low temperature resistance
Whether in extremely cold or hot environments, butyl tape can maintain stable performance. Its operating temperature range is wide, from -40℃ to 90℃, and it is suitable for sealing needs in various harsh environments.
-
(4) Dimensional stability
During long-term use, the dimensional changes of butyl tape are small and it can maintain its original shape and size, thus ensuring the durability of the sealing effect.
2. Excellent mechanical properties
(1) High tensile strength
Butyl tape has high tensile strength and can withstand large tensile forces without breaking. This feature ensures that the tape will not be easily damaged during construction and use.
(2) Good elasticity
Butyl tape has good elasticity and can adapt to the deformation and displacement of the adherend. In the case of building settlement and vibration, butyl tape can maintain good sealing performance.
(3) Good extension and recovery performance
Butyl tape can undergo a certain deformation when subjected to external force; when the external force is removed, it can quickly return to its original shape. This feature makes butyl tape more flexible and reliable during use.
3. Chemical resistance and corrosion resistance
(1) Chemical resistance
Butyl tape has good resistance to various chemical substances and can work stably for a long time in harsh environments such as acid, alkali, and salt. This property makes it widely used in the chemical, electronics and other industries.
(2) Corrosion resistance
In addition to chemical resistance, butyl tape also has good corrosion resistance. In harsh environments such as humidity and salt spray, butyl tape can maintain its performance and appearance for a long time.
Construction method
1. Use method for new construction projects
(1) Construction method for new steel structure roof projects
- Base treatment: Ensure that the joints of the metal plates are clean and free of stains.
- Measurement and cutting: Cut the butyl tape to the appropriate size according to actual needs.
- Paste and fix: Paste the butyl tape along the joint and press it by hand to make it fit tightly.
- Subsequent treatment: Perform necessary inspection and finishing work after pasting.
(2) Waterproof treatment of construction joints of subway tunnel structures
- Surface treatment: Clean the surface debris of the construction joint and keep it dry.
- Cutting and attaching: Cut the single-sided aluminum foil butyl tape of the appropriate size and stick it on the construction joint.
- Compacting and fixing: Use special tools or rollers to compact the tape to ensure that it is tightly bonded to the substrate.
- Inspection and acceptance: Finally, check whether the pasting effect meets the design requirements.
2. Repair method of steel structure roof leakage
- Cleaning the surface: Remove the original sealant at the overlap of the metal plate.
- Grinding: Grind and remove rust from the repaired part and wipe it clean.
- Cutting and attaching: Cut the single-sided aluminum foil butyl tape of appropriate size according to the joint of the leaking part and directly cover the joint.
- Compacting and fixing: Use fingers or tools to compact the repair part to ensure that it is firmly bonded.
- Inspection and acceptance: Observe whether there is still leakage and make necessary adjustments until the problem is completely solved.
3. How to use single-sided non-woven butyl tape
- Preparation stage: Make sure that the skylight board is installed and the joint is clean and dust-free.
- Cutting steps: Measure the required length and cut the corresponding size of single-sided non-woven butyl tape.
- Remove the isolation paper: Gently tear off the isolation paper on the back of the tape to expose the sticky side.
- Precise attachment: Align the sticky side to the joint and slowly lay it down to avoid bubbles or wrinkles that affect the aesthetics and waterproof effect.
- Compacting treatment: Use a soft rubber hammer to tap the pasted position to strengthen the bonding strength to ensure that it does not fall off. At the same time, be careful not to use too much force to cause deformation and damage the structural integrity of the material itself.
- Final inspection: Carefully check whether every corner has been properly handled and there are no missed places. Only then can you close the on-site cleaning tools and prepare to leave.
