This article introduces a new method to design the waterproof property of moistureproof agent sealed floor.

The intumescent flame retardant has excellent flame retardancy(LOI value up to 34%),greatly reduced flame retardant consumption,remarkably impreoved no-blooming and moisture proof propercies in comparison with other two intumescent fl.

In order to meet request of painting with waterproof and moisture proof for wall of cooling tower in power plant, a kind of Styrene Acrylic painting with high quality and waterproof is developed, having economic ability and manufacturability.

It also makes a brief description of design principle of moisture proofing and thermal insulation technology for exterior -protected construction that provides a systematic thermal engineering design method for design of energy saving building.

A New Way to Dampproof for Ammunition Hole Depot in Island;

A kind of chemical reagent AH was chosen , the effects of the concentration of AH ,the reaction temperature ,thereaction time and pH on dampproof of leather protein powder (LPP)were discussed by means of orthogonal design .

The result showed that different carriers were different in their effects on such quality indexes as CV, classification due to vibration, anti-caking property, dampproof property and the storage stability of I~- and Fe~(2+).
