Chlorinated Polyethylene Membrane for High Speed Rail

Chlorinated Polyethylene Membrane for High Speed Rail

The chlorinated polyethylene waterproofing membrane is a colorful elastic waterproof material made of chlorinated polyethylene resin as the base material.

Product Description

The chlorinated polyethylene waterproofing membrane(CPE waterproof membrane) is a colorful elastic waterproof material made of chlorinated polyethylene resin as the base material, mixed with chemical additives and fillers, and processed by plastic refining, hot compounding, calendering, crimping, and other processes. The product divides into N class homogeneous and L class fiber conforming.

The main material of chlorinated polyethylene, no double bond in its macromolecular structure, has good aging resistance, oil resistance, and chemical resistance;blending with rubber, high elasticity, high elongation, and good low-temperature resistance, and has strong adaptability to foundation settlement and concrete shrinkage joints.From this aspect, chlorinated polyethylene rubber blended waterproofing membrane has the dual characteristics of chlorinated polyethylene and rubber, is a better waterproof membrane for high speed rail.

Features of Waterproof Membrane for High Speed Rail:

1. High tensile strength, strong seepage resistance, good low-temperature flexibility, small expansion coefficient, strong adaptability to deformation, big coefficient of friction, can be used with a variety of adhesives, good bonding effect;2. Aging resistance, long service life;3. It can directly construct on freshly cast concrete, which can effectively shorten the construction period and save the construction cost.

Cautions:

①Configured paint should use up within 20 mins, with the allocation.②Rainy days, snowy days, more than five winds, the temperature is higher than 35 ℃ or lower than 5 ℃ is not suitable for construction.③Pay attention to ventilation when storing and transporting, avoid direct sunlight, and prohibit direct with acid, alkali, oil, and chemical solvent. Place in a cool and dry place, suitable temperature -15℃~35℃. The storage period is 12 months.

Construction Method:

â‘ Preparation: clean up the oil, slick, cement slag, loose layer, etc. On the base surface, treat and repair the unevenness; do waterproofing reinforcement layer on specific parts first before large area construction.â‘¡Construction: paste waterproofing materials with polyurethane or cement-based adhesive. Side painting binder while paving waterproofing materials, while scraping board in the upper part of the coil back and forth scraping solid, forbidden to have bulging, blistering and other nomena, polyurethane waterproofing coating or cementitious adhesive for sealing.
