Butyl tape encyclopedia
Butyl Rubber, or IIR, is short for Isobutylene Isoprene Rubber. It has good chemical and thermal stability, air tightness and water tightness. Its transmittance to air is only 1/7 of rubber, 1/5 of styrene butadiene rubber, and the transmittance to steam is 1/200 of rubber, 1/140 of styrene butadiene rubber.
This gas is difficult to penetrate the material, waterproof sealing effect is even better. As well as its outstanding weather resistance, according to the relevant test data, butyl rubber high temperature resistance can reach more than 120℃, low temperature resistance -40℃.
According to the survey done before China building waterproof and zero consulting, building waterproof leakage rate is high as high as 90 percent, many large enterprises have also set up repair departments, and in the process of rapid red repair products are acrylic salt and butyl tape.
First, metal plate roof eaveaves ditch construction method
(1) after the installation of the prefabricated eaves ditch, the concrete surface of the parapet above the eaves ditch is cleaned, and the basic treatment agent is brushed.
(2) After the base treatment agent solidifies, install the flood board to ensure that the installation is firm and closely combined with the wall.
(3) Wipe the water board clean, paste the single-sided aluminum foil tape at the joint between the water board and the cement wall surface, and squeeze it in order to make it firmly bonded. Do not use waterproofing if you use 80mm wide single-sided aluminum foil tape.
Two, steel structure roof leakage repair engineering construction method
The metal plate is leaking in contact
(1) Clean up the original sealant at the metal plate lap.
(2) Wipe the metal plate of the repaired part clean.
(3) According to the water leakage joint situation to choose different specifications of single aluminum foil tape;
(4) Cover the seam directly with single-sided aluminum foil tape;
(5) After bonding, roll the repair in order to make the single-sided aluminum foil tape firmly bonded at the joint.
Three, pressure steel plate and cement wall surface combined with water leakage
(1) Clean up the original silicone glue connecting the molded steel plate and the cement wall;
(2) then wipe the joint between the pressure plate and the cement wall; Cement wall shall not be sand requirements, conditions should be brushed base treatment agent.
(3) Single-sided aluminum foil tape is pasted at the joint of the metal plate and the cement wall surface. After bonding, the repair is rolled in order to make the single-sided aluminum foil tape firmly bonded at the joint.
