Cooling mattress Size: 90*90 cm single 90*140 cm double Thickness: 0.3 cm Style:plian Shape: rectangle Pillow: 30*45 cm Materials: External: polyester 65%, cotton 35%ú¿antisepticú¬ Internal: pvc plastic Package of gelatin: non-woven fabricsú¿polyesterú¬ Main componets of gelatin: water absorbent polymer, glycerine, cellulase, water, antiseptic Functions of product: the phycical cooling which can make the surface temperature of human body lower 2-3 degree, resulting in cooling and saving energy. The principles of the work about the gelation mattress: 1.At first, making use of the high specific heat of water to absorb the heat quantity of human body, then rapidly abstracting heat by the hydrophilic gelation of 3-d network structure to achieve cooling. 2.The hydrophilic gelation of 3-d network structure is consist of many long chain molecules crosslinking. It has stretch and cohesion, and keeps being solid-state and containing water through a homogeneous system formed by the hydrophilic group of hydrogen bond and vander wale force and the hydrone. The moisture of hydrophilic gelation is about 66%. Size: 90*90 cm single 90*140 cm double Thickness: 0.3 cm Pillow: 30*45 cm
