How can medical plastic film be changed into hydrophilic material?
The surface of the hydrophilic material is spread and can act by capillary action, and the water is sucked into the material from the water. The hydrophobic surface of the water can only be spread and the water penetrates into the capillary of the materialMaterials such as building materials, hydrophilic materials, cement, concrete, sand, stone, brick, wood and other materials, asphalt, paraffin wax and some plastic hydrophobic materialsHydrophilic materials are used more in bonding designs to make buildings more stable; hydrophobic materials are used as moisture-proof, waterproof and antiseptic materials, and hydrophilic materials are treated by surface treatment to reduce their water absorption
Water and air, liquid, solid and gas phase intersection for droplet surface tangent tangent angle by water and surface material wetting angle if the wetting angle is less than or equal to 90 of that material and water interactions in water to force water to wet material materials so called hydrophilic anti wetting angle of >90 degrees if the materials and instructions water to water so the water wet material forces between hydrophobic materials said
Hydrophilic material: with polar groups Pro water ability to attract water or dissolved in water type surface wetting Yishui solid material for hydrophilic material materialMaterial and water contact, some materials can water moist, material can water wet two kinds of phenomenon, said the former hydrophilic hydrophobic
