★Construction Technology
One、Hot-melt
1, with cement mortar grassroots, the grassroots to ensure smooth, firm, dry and clean. There can not be loose, sand, peeling phenomenon;
2, in the grass brushing cold base oil;
3, after a cold base oil sulfate, and additional processing nodes sealing layer laying;
4, heated with a blowtorch and grassroots sheet, bottom sheet and other hot-melt, immediately roll shop, shop side edge compaction;
5, while the hot-melt web is not cold, iron the seam edge roll trowel timely packer, and hot melt pressure compensation torch dense;
6, carry out the web closing header processing, so that fixed and sealed;
Two、Cold Construction
1, according to the requirements of hot-melt sealing process node and grassroots leveling and laying of additional layers;
2, even brushing agent, while brushing the side of the web shop rolled forward, and in a timely manner with the roll compaction process;
3, timely gelling agent overflow seal;
4, good income header processing web.
After construction Press GB50207-2012《Roof Engineering Quality Acceptance》or GB50208-2011《Underground Waterproof Engineering Quality Acceptance》Acceptance。
★Storage and transportation
1、Storage
During storage and transport of different types and specifications of products should be stored separately and should not be mixed. Avoid the sun and rain, pay attention to ventilation. Storage temperature should not exceed 50 ℃, stand up storage only single, neutral place during transport of not more than two layers.
2, Transportation
Prevent tipping or horizontal pressure, covered with tarpaulin when necessary during transport.
3, the storage period
Under normal storage, transport conditions, starting one year from the date of production of the storage period.
