Dynamic Waterproof Characteristic of Waterproof Material——Seepage Prevention on Underground Works Wall Surface with Deformed Cracks;

The paper sized by the fluorine emulsion acquired good water and oil-resistant ability, the maximal degree of the contact angles for the sized paper to water and liquid paraffin were respectively 107°, 93°, at the same time the paper's strength, fracture-resist degree .

This paper discussed the water resistance of various coating agents, UV protection of conventional and nano materials, as well as the compatibility between nano UV protective agent and solvent, PU coating agent, PA coating agent, pearl powder, silver paste and so on.

Using denatured biomass as briquette binder in the laboratory,the influence of NaOH solution,biomass quantity and composite material additives(MgO and MgCl2) on briquette strength,waterproofing property and ignition temperature was studied.

The size of formation porosity, contact angles,waterproof and permeability of fabrics coated by polyurethane were tested and studied.

The civil honeycomb like briquette and boiler briquette with sulfur fixation and waterproof have been produced.

Its advantages may be considered from such aspects: (1) beautifying the architectual configuration to improve the urban landscape; (2)increasing the waterproof ability of the roof for durability; (3)improving the thermal insulation to save energy; (4)helping the development of related sectors of.
