Polyvinyl chloride PVC waterproof membrane

--d ---d<=1. Product Overview
d --d ---d:<= Polyvinyl chloride waterproof membrane is a polymer waterproof sheet with excellent performance, mainly made of resin. The raw materials are added with plasticizers, anti-UV agents, anti-aging agents, stabilizers and other processing aids to produce formed polymer waterproof membranes through extrusion. Product width, meter thickness, standard length, reliable quality, convenient construction. Due to the unique product formula, this product has a product life that far exceeds that of ordinary waterproof materials. The entire waterproof system has a long life, giving the membrane excellent dimensional stability and a low thermal expansion coefficient, which improves the ability of the membrane to withstand direct exposure to the natural environment. Long term performance.

><=4. Construction technology
d --d ---d:
d --d ---><= Strength, thickness, The moisture content and other indicators should meet the design requirements of national specifications before waterproofing membrane construction can be carried out.
d --d ---d:
d --d ---><= Determine the laying direction and sequence of planned membranes and arrange them naturally on the base layer according to the outline of the waterproof layer. Smooth and straight, no bending, overlap according to the overlap width required by the specification.
d --d ---d:
d --d ---><= Fix according to the selected fixing method, such as mechanical fixing, full gluing, strip gluing, etc.
d --d ---d:
d --d ---><= The welding overlap of waterproof membrane should be wiped clean and dry. When welding, hot air welding should be used. The welding tip should be aligned with the welding direction. The angle pressure roller should be parallel to the welding nozzle and should be kept at a distance of approximately 100%. The welding edge should have bright color molten ooze and should not be scorched.
d --d ---d:
d --d ---><= The end of the coil should be fixed with a batten and sealed with sealant and cement mortar.
d --d ---d:
d --d ---><= After the construction of the waterproof part of the entire project is completed, comprehensive quality inspection and processing will be carried out.

5. Precautions
d --d ---><=. When laying waterproof membranes, attention should be paid to the construction environment temperature and the use of membranes. Temperature -℃ or above. When using the full-bond method for construction, the operating temperature of the coil can only be above ℃.
d --d ---><=. When paving waterproof membrane, additional layers should be made in special parts.
d --d ---><=. Pay attention to construction protection. Before the end of daily construction, the membrane should be temporarily fixed to prevent it from being blown up by the wind.
d --d ---d:. The construction of the waterproof layer should be carried out after the previous process is completed and no cross construction is allowed. If you need to install equipment on a roof with waterproof membranes, an additional layer should be added to the foundation of the equipment. If you need to build a high-rise house on the waterproof layer, it must be done after the waterproof layer has been inspected
. The membrane floor is The wear-resistant layer should be rolled outward on the tube core for outer packaging and should be packaged in corrugated cartons. During transportation, they must not be exposed to impact, sunlight, or rain. The indoor storage air should be circulated and the drying distance should not be closer than the heat source. Rolled flooring should be stacked upright
