Study Of The Formula And The Processing Roperty Of Wide Chlorinated Polyethylene Aterproof Roll

The study background of this project is aiming to the detection report ofseveral railway bureaus about the damage issue of bridges used in railway in2003. Find that the worst issue leading to damage is coming out of rain. Sofirst of all, find a type of waterproof material to avoid rain damage is the mostimmediate thing. because of the wideness of waterproof materials are less than2.5meters, workman should put different types of waterproof materialtogether by sealing them to avoid rain. But there would be many cracks byenvironment changing, such as UV light, rain and wind. So the properties ofwaterproof materials would decrease to bad, result in short life. At the sametime, the using construction means of waterproof materials is to sprayPolyurea waterproof coating, which is not a flame retardant and anenvironmental protection material, so it is very important finding a cheap andeasy operated waterproof material, owning best comprehensive performance.The study bases on this background, aiming to find out a waterproofmaterial, which could replace the Polyurea waterproof coating, at the sametime, owning enough wideness to cover the whole face of railway bridge, sothe wide Chlorinated Polyethylene Waterproof Roll comes out. This study aims to find out the proper formula of the wide Chlorinated PolyethyleneWaterproof Roll. The key issue of this formula is the processing property,fitting to squeeze processing. If this work can be done, the wide waterproofroll coming out. This type of waterproof material owns best comprehensiveproperties and longer life.The first content of this study is to get proper formula of enhancedsystem, owning proper processing property. Secondly study the plasticizingsystem and lubricating system, getting proper formula. In the end get theperfect formula of the study. The next step is to process the formula and adjustthe ratio to get the last formula.
