Examples of applications for ultra-resistant membrane butyl rubber sealed waterproof protective film.

Engineering Overview
An industrial plant project roof using metal plate, rock cotton composite steel plate, metal roof panel is not set waterproof breathable film and air insulation film, resulting in indoor water vapor and external water into the metal roof panel insulation layer, insulation layer long-term water absorption saturation. During the survey, it was found that condensation and dripping were produced on the roof panel between the 37-43 axis/B-E axis of the plant and the following equipment lines, and the more serious the phenomenon was when the humidity of the external environment was greater.
site equipment survey
the temperature in the black area suddenly decreased, suspected that the water content inside the metal roof insulation layer is higher than other parts of

.
Cause Analysis
Structure and waterproof design treatment is not properly handled, the metal roof panel is not set waterproof breathable film and air insulation film, resulting in indoor water vapor and external water into the metal roof panel insulation layer, insulation layer long-term water absorption saturation, resulting in local insulation function failure
Outdoor and indoor air circulates through defective areas, resulting in condensation and dripping in the local areas of indoor roofing.
Conductive solution
program design
metal roof surface grass-roots clean-up, grass-roots clean dust-free, non-pollutants,
using ultra-resistant film-resistant butyl rubber sealed waterproof protective rubber coating system for the overall refurbishment of metal roofing. Construction, the ultra-resistant film butyl rubber waterproof protective film in a cold self-sticking way pasted on the steel plate surface, each film bonding width of not less than 80mm, the film surface of the site before the connection with fluorine film surface modifier treatment, repeated roll pressure or scraping dense;
metal plate is attached loose riveting and then coated, filmed, and reinforced with
homogeneous tape;
Construction points
thin self-adhesive coils in the uneven metal roof panel construction, need to master the following points, in order to ensure flat aesthetics and efficiency:
line;
pre-paved after the original roll back to the line, to ensure straight;
parallel to the roof (eaves), from low to high water direction to the patch;
Unwrap the coil end 30-50cm wide isolation film, flat paste on the real house panel, the isolation film from the finished roll below, to ensure that the dew offline and the finished roll parallel, the lead out of the isolation film with a round stick to close the roll, to
avoid the unmasking film unevenly wrinkled coil; , after the sequence of paving, first do not expose the film, the coil with isolation film spread on the roof panel, to ensure that the film and trench corrugated clothing close, and then the front end with rubber scraper gently fixed and then closed the isolation film, so that the glue surface and metal plate naturally close, with scraper scraping dense, and then lay forward. The small concave surfaces of the roof panels need to be evenly stuffed with scrapers to ensure full sealing.
metal roof renovation process and paving demonstration legend:
construction process
brow clean-up→ node consolidation→ additional reinforcement treatment→ large-faced mucosal fort ultra-resistant membrane-resistant butyl rubber seal waterproof Protective film → edge treatment
construction tools
cleaning materials
silicone rollers, rubber scrapers
pull riveting guns, nails
blades, scissors or beauty Tool
bullet line tool
sprayer, paint brush
construction process
1, material preparation
main material: roof fort ultra-resistant membrane butyl rubber seal waterproof protective film
: House fort ultra-resistant membrane butyl tape
soilable material 2: fluorine film surface modifier
should be prepared before the main auxiliary material, do not destroy the original packaging of the material, store in a cool place, away from the source of fire, to avoid direct sunlight.
2, weather conditions
should be above 5 degrees Celsius temperature conditions, not in rain, snow and more than five strong wind weather construction.
3, grass-roots clean-up
to ensure that the original roofing system of the pressed steel plate must have a reliable connection with the main structure, the connection between the plates to be smooth, continuous, roof panel damaged parts need to be repaired.
clean up the roof panel surface garbage, dust, stains, the aging cracked waterproof, sealing materials are completely eliminated.
remove the silt from the trench and eaves.
4, node consolidation
will be loose fasteners re-tightened, replace rusted fastening screws, tie the open deformation of the part of the riveting fastening. Remove the steel strips that are reinforced later, mark them well, and restore them after the large-faced paving is finished.
5, additional reinforcement treatment
the metal plate hooking site, roof ridge upright lock edge, eaves, facade and flat junction and other parts with the roof fort ultra-resistant membrane-resistant rubber sealing waterproof protective film sealing tape for reinforcement treatment;
the lighting window and the metal house panel are easy to produce gap leakage site, should be paid attention to. When construction, the reinforced steel belt should be removed, clean the tie-up edge and fastening belt, spread a 100mm wide ultra-resistant membrane butyl sealing tape for sealing reinforcement treatment, repeated roller pressure or scraping tight, to be after the completion of the large-faced paving to restore the reinforced steel belt.
6, large-faced mucosal fort ultra-resistant film-resistant butyl rubber seal waterproof protective film
first put the wire, the construction of pre-paved, the natural loose film film film sheet according to the outline arranged on the original roof steel plate, flat straight, not distorted, long and short edge tie, and make appropriate cutting, in order to ensure that the short-sided mating position in the original pressure plate wave valley.
the film surface of the hooking site before the lifting to carry out modified treatment, thin brush a layer of modifier, refers to the drying of the finger after (1-3 minutes) to 2 hours to complete the hook.
laying film film film long edge direction should be parallel to the eaves, the direction of water from low to high paving, edge paving with scraper scraping tight, the joint part with repeated roller pressure or scraping tight.
film should be closely pasted with the metal plate, concave surface with scraper carefully squeezed into the solid, not empty, drum.
7, edge pressure bar treatment, restore reinforced steel bar.
Construction Precautions
Because the reflectivity of the surface of the white coil is very high, workers should wear sunglasses
(
filtering ultraviolet light) to protect the eyes when construction

Should try to avoid walking, dragging or storing items on paved roofs, avoid damaging the roofs completed by construction;
coils should not be stacked centrally on roofs to avoid deformation of roofing grasses caused by oversized local loads;
drainage measures should be done before construction to ensure that rainwater can be drained in a timely manner
