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:It is good for black roof with waterproof paper
No film or PE film (black surface) coil is generally not used for the roof; if the roof is often on the need to lay in the coil above the 5 cm thick cement mortar to do the protective layer or the choice of sand and shale surface waterproof Coil. Lough membrane (silver surface) The role of the membrane to play the radiation can be used directly for the roof without any protection.
Q:How to distinguish the degree of sbs waterproofing membrane?
Method 2: send the laboratory to do low-temperature flexible test. With the eyes and hand pull and other methods can not judge, if the experienced SBS production technology staff, from the hand pull, bending and other methods to determine the initial performance.
Q:Do you know how many square meters of waterproofing membrane to send a set of tests?
Elastomer Asphalt Waterproofing Sheets: Take a roll out of the outer roll head 2500mm, the vertical cut 800mm full-width coil sample 2. 10000 square meters for a group, the lack of a group also.
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:BS waterproofing membrane is modified? There are not a few thick drawings, how to do
Do not indicate the thickness can contact the design unit, you can also judge according to the waterproof level
Q:The shortcomings of polypropylene waterproofing, and the shortcomings of modified asphalt waterproofing membrane
Waterproofing membrane in the waterproof construction in accordance with the shape of the waterproof base of the bulk of the truncated, for the complex shape of the grassroots need to multi-block splicing, waterproofing membrane overlap at each other more difficult, due to the impact of multi-block splicing waterproof Layer of beauty; then completely completely sealed will become the main problem, the biggest hidden dangers, the most opportunities is the coiled parts of the coil; then high-grade waterproofing membrane with decades of durable durability,
Q:The difference between waterproof linoleum and 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 are the advantages and disadvantages of waterproofing membrane?
The waterproof membrane study its drawbacks: waterproofing is performed when the amount of coating material according to the cross-sectional shape of the waterproof base waterproof construction, the need for a complex shape of the base layer a plurality of splicing, waterproofing overlap each other at the bonding difficult than Large, due to the impact of multi-block splicing waterproof layer of beauty; then completely absolute seal will become the main problem, the biggest hidden dangers, the most opportunities is the coiled parts of the coil; then high-grade waterproofing membrane with a few decades durable for a long time, but the country is still less matched the binder, and the binder material itself due to environmental factors such as loss of adhesion is often ahead of function, thus leading to the failure of the waterproof self-evident; Furthermore Waterproof membrane after the construction of the protection and leakage after the maintenance is also a problem, exposed waterproof layer of foreign mechanical damage prevention is very important, waterproof membrane and the grass-roots bonding, whether full of shops, shop, shop air, between the base layer and the web would be to go aqueous layer, regardless of any part of the cross-cutting breakage, degumming, drooling (even the only one), the entire coherent thereto waterproof power level Will lose all bad, if you can not find damaged and defective parts, the local repair is not possible, then only redo waterproof layer.
Q:Can waterproof sheets be used on steel roof panels?
Waterproof coils can be used on steel roof panels. Waterproof membrane: waterproofing membrane is mainly used for building walls, roofs, and tunnels, highways, landfills, etc.,
