Waterproof mortar: mixing cement mortar waterproof agent. Parts for applications requiring waterproofing basements, water tower, pool, tank, etc., can also be used to repair a leak. Radiation mortar has the following two ways: ① barite mortar. Cement, barite, barite sand made by adding water. Major capacity (2.5 t / m 3) of X, γ-ray energy from the barrier effect. ② boron cement mortar. To mortar adding a certain amount of boron (such as borax, boric acid, boron carbide, etc.) made with anti-neutron radiation performance. Common ratio of lime: cement: barite powder: calcium = 1:9:31:4 hard boric acid (weight ratio), and add appropriate amount of plasticizer. Polymer mortar has the following two ways: ① resin mortar. Added synthetic resin curing agent (such as ethylene diamine, benzenesulfonyl chloride, etc.) and powder, fine aggregate preparation. Commonly used epoxy mortar, mortar phenolic resin, epoxy furan resin mortar. It has good corrosion resistance, waterproof, insulating properties and high bond strength, often used for anti-corrosion surface. ② polymer cement mortar. To add the appropriate amount of polymer cement mortar in adhesives (such as polyvinyl alcohol), pigments and small amounts of other additives, made from mixing with water. Used for external walls, can improve the mortar bond strength and durability of finishes.
