High polymer modified bitumen waterproofing membrane thickness selection, roof waterproofing grade, anti-way number, high polymer modified asphalt waterproofing membrane
Class I, three or more roads, not less than 3mm
Class II, two-way fortification, should not be less than 3mm
Class III A fortification should not be less than 3mm.
If there is a heavy-weight cage on the waterproof layer of the roofing membrane or the deformation of the lower layer should be preferentially used, the coiled material should be preferentially coated with an empty layer of sticky strips, but the coil and the lower layer are in the 8mm-scale coil around the roof. All the rolls should be covered with a full-faced façade or a large-scale sloping surface. Therefore, the flexible waterproof layer of the bottom plate should be provided with a protective layer. The plastic outer layer of the flexible outer layer is immersed in the waterproofing of the underground station. The concrete on the surface of the water will be eroded by the groundwater. The groundwater in China is the shallow groundwater, and the infiltration coefficient of the s8 waterproof concrete is 5~8×10-8cm. /s, and the concrete itself may still have the premise that the protective layer is insufficient and the steel is densely deflated.
Polymer modified asphalt waterproofing membrane roofing waterproof layer paving operation process. Safe production guarantees that all employees will be educated in peace and culture, and organize safe delivery. Flexibility Six test pieces of at least five test pieces to reach the demarcation of the indicator will be awarded. e The joint of each roll shall not span a shorter length and shall not be less than cut and neat and lengthened. Among them, EPDM rubber has advanced international advanced cold feed extrusion and continuous vulcanization equipment. DuPont produces EPDM rubber and domestic high quality raw and auxiliary carbon black reinforcement nano modifier plasticizer vulcanization promotion. The agent and the like are added to the high-elastic synthetic polymer by the fine filtration, the extrusion molding, the continuous vulcanization and the tempering. When rolling the coiled material, the cement slurry should not contaminate the self-adhesive surface of the edge of the coil. If there is inadvertent pollution, it should be cleaned and cleaned in real time.
Polymer modified asphalt waterproofing membrane roofing waterproof layer paving operation system.
(1) Actively cooperate with the various safe works of the General Contracting Unit Project Department, and collect admission education and safe handicrafts. The speed of moving the two rolls is different and coordinated. The waterproof material should have sufficient adhesion with the concrete pavement layer on the bridge base to ensure that the upper and lower layers are in the process of application, and it is strictly forbidden for non-situ personnel to enter the site.
(2) Applying the lower layer of adhesive on the lower layer of the predetermined paving. Any suitable adhesive for the coil can be used as a thinner to dilute and mix the average. After using the brush, the complex part should be painted with a brush. It is permissible to have a gel block to avoid brushing back and forth in one place to avoid "biting the primer to form a gel and affecting the paste."
"Cold paste construction of high polymer modified bitumen waterproofing membrane. In the century, China's self-adhesive coil material is mainly used for roof waterproofing. It has been applied to underground waterproofing since the beginning of this century. The construction site and the warehouse must have a relatively large The sign of “No banfire” is marked. It is feasible to study and cultivate the scale. When the waterproof layer of the daughter wall is applied, the plane should be laid first, and then laid down from the bottom to the bottom, so that the coil is close to the negative angle and cannot be hollowed out.
(3) Code change asphalt sbs-z fine sand s mineral grain (sheet m polyethylene film pe aluminum film a.. & 16% of the balance after the two aspects of the thermal invariance index. Group approved by uniform variety The products of the uniform grades are in batches and are in batches. They can be used in various parts of underground buildings (collection of basement floor, elevator shaft, underground outdoor wall, basement roof and roof, podium, balcony (roof, bathroom) Waterproof and moisture-proof. The domestic bridge bridge deck waterproof growth profile in China, the highway reinforced concrete bridge cultivated before the 0th century 0 years ago, the foundation is not waterproofed (the railway bridge is an exception, the design technology of the former Soviet Union has always been used, the bridge components are Adopting a felt and two oil waterproofing treatment before leaving the factory, it has achieved an inevitable end.
"The hot melt method is applied to the hot melt type high polymer modified asphalt waterproofing membrane.
In the United States, the number of bridges that needed to be repaired in the 20th century increased dramatically, which led to an increase in the effectiveness of related research. It is not allowed to calculate the dampness of the sky above the night wind level in the rain, snow and fog.
