Self-adhesive polymer waterproofing roll-roofing manufacturers: self-adhesive waterproofing roll-roofing in the use of common problems

Self-adhesive polymer waterproofing roll-roofing is a polymer self-adhesive waterproofing roll-roofing, is a polymer HDPE homogeneous waterproofing roll-roofing as the subject material, coated with a certain thickness of non-leachable hot melt adhesive, with a polymer special isolation sand or PE silicone oil film isolation and made.

Self-adhesive polymer waterproofing roll-roofing material is characterized by full bonding with the substrate, even if the local breakage will not leak, so it is very important to ensure full bonding quality, as the coil has the characteristics of self-bonding, in the process of operation is easy to appear "in advance" bonding phenomenon, that is, the coil insulation paper uncovered on the substrate bonded, often leading to Uneven spreading and blistering, therefore, the following points should be noted in use: 1:

1. when pasting coils, always pay attention to alignment with the baseline to prevent deviations difficult to correct, coil paste, the coil shall not be stretched, paste after rolling with pressure rollers from the middle of the coil to both sides to expel air to make the coil paste on the substrate, do not prematurely peel the coil overlap part of the insulation paper to avoid contamination of the adhesive layer or misapplication, should be removed before pasting the coil on the back.

2. the substrate must be clean, if there is a weak surface of the base layer, it will form coils or even pull up the phenomenon of adhesion of the substrate, so the requirement of the substrate must be strong and clean.

Self-adhesive waterproofing roll-roofing material can be selected according to the site conditions of the project wet store, empty store, solid machine, hanging store and other construction methods, construction more dexterous, better waterproofing effect, can be wet construction, no leveling layer, low requirements for the lower layer, not affected by the climate and the lower humidity, dry season construction and project duration has its unique and obvious advantages, no shielding layer on the coil, can be directly poured reinforced concrete.

Self-adhesive polymer waterproofing roll-roofing manufacturers: the performance characteristics of polymer waterproofing roll-roofing

1. atmospheric stability, atmospheric stability refers to the ability to resist erosion under the long-term integrated action of sunlight, heat, ozone and other chemically corrosive media, aging resistance, thermal aging retention rate and other common indicators.

2. temperature stability, temperature stability refers to the waterproofing roll-roofing material at high temperatures without flow, blistering, sliding, low temperature without cracking performance, that is, the ability to maintain the original performance under certain temperature changes, commonly used heat resistance, heat resistance and other indicators.

3. mechanical strength, ductility and fracture resistance, refers to the waterproofing membrane in a certain deformation conditions, can withstand a certain load, stress or not fracture performance, tensile strength, tensile strength, elongation at break and other common indicators.

4. flexibility, flexibility refers to the ability to maintain flexibility at low temperatures, to ensure easy construction and does not occur brittle fracture is very important, often expressed in terms of flexibility, low-temperature flexibility and other indicators.

5. water resistance, water resistance refers to the waterproofing roll-roofing material under the action of water and water immersion after the performance of the basic unchanged, impermeable under the action of pressure water, commonly used water impermeability, water absorption rate and other indicators to indicate.
