Q:What is the meaning of "channel" and "layer" in the practice of polymer waterproofing membrane?
In addition, the two did not meet the required thickness of the waterproof layer, according to certain requirements for laminated composite, two waterproof layer can be considered a waterproof. Such as 1.2mm polyurethane + 1.2mm self-adhesive coil (laminated construction rather than separate), can be used as a waterproof, although with two kinds of materials to do a two-story waterproof, and can not be considered two waterproof. The thickness of the laminated composite waterproofing layer can be thinned, and its provisions may be reflected in the new "roofing engineering technical specification" to be published.
Q:What is waterproofing membrane?
Waterproof membrane is mainly used for building walls, roofs, as well as tunnels, highways, landfills, etc., to resist the external rain, groundwater leakage can be curled into a roll of flexible building materials, as the basis for engineering And no leakage between the building connection, the entire project is the first waterproof barrier, the entire project plays a vital role. The main products are asphalt waterproofing membrane and polymer waterproofing membrane.
Q:What is BSB waterproofing membrane
SBS waterproofing membrane is: The thermoplastic elastomer is used as a modifier to make impregnated and coated materials, and the upper surface is covered with a polyethylene film, fine sand, mineral sheet (granule) or aluminum foil, copper foil and other insulating material made of curled sheet waterproof materials. Styrene-Butadiene-Styrene means: styrene-butadiene-styrene. SBS rubber modified petroleum asphalt for the invasion of the cover layer to polyester fiber non-woven fabrics, jute cloth, fiberglass mats were made for the fetal base, the plastic film for the anti-sticking isolation layer, the selection, ingredients, eutectic , Invasion, composite molding, curling and other processes processing production.
Q:What is the PEDM waterproofing membrane material?
EPDM waterproofing membrane (EPDM) is the main material with ethylene propylene rubber, adding anti-aging agent, accelerator, and adding nano-materials, so that the waterproof membrane weather resistance, heat resistance, low temperature resistance has greatly improved
Q:Waterproof building materials after the construction of drums, bubble is what reason?
Reason 3: synthetic polymer waterproofing membrane construction, if the adhesive is not fully dry on the eager to paving the membrane, resulting in a solvent residue in the coil inside, when it evaporates, it will form a bubble. Control measures: the use of cold and cold method of paving, the brushing of the adhesive to be uniform, to be dry when the handle (refers to touch) is not bonded, before paving the membrane, while compaction. In particular, to prevent the accumulation of adhesive too thick, dry operation caused by the film from the drum.
Q:Is the waterproofing membrane an insulating material?
3, with a metal carcass resistant root puncture waterproofing membrane, such a coil in the metal copper fetal base, there are other metal fetal base of the coil.
Q:What is the difference between SBS and APP rolls?
Compared to the use of SBS waterproofing membrane to use a larger range. But each has its own advantages and disadvantages, according to the local environment and the actual situation of the building in combination with the characteristics of two kinds of coil to choose materials. You have to compare the next, I can only tell you SBS waterproofing membrane prices than APP waterproofing membrane high.
Q:Polyethylene polypropylene waterproofing membrane forming. Secondary molding, what does it mean? How to distinguish?
Polyethylene polypropylene waterproofing membrane from the middle of the "polyethylene" chip, two-sided composite "polypropylene non-woven" made, one method is in the extrusion production of polyethylene film at the same time, when the polyethylene is still in a soft state , In the upper and lower sides of the membrane composite polypropylene non-woven, the temperature can not be too high and polypropylene buried too much, the temperature can not be too low, otherwise the sticky on the sticky.
Q:It is good for black roof with waterproof paper
SBS surface is divided into: PE film, no film, Liao film, sand surface, shale surface and other categories. The blacks mentioned in the problem belong to PE film and no film, and the silver is the membrane of the membrane. There is no difference between the use of good or bad comparability.
Q:PVC waterproof membrane effect how
4, hot-melt method: the use of flame heater melting hot-melt waterproofing membrane at the bottom of the hot melt adhesive bonding method of construction.
