Highway caulking mortar is a new type of building waterproof coating and waterproof caulking material made by plasticizing polyvinyl chloride coal tar with appropriate amounts of modified materials. It has a wide range of applications, strong adhesion, good waterproofness, elasticity, cold resistance, corrosion resistance and anti-aging properties. It has a wide temperature adaptability range, easy construction, long service life and excellent waterproof effect. Technical Performance This product is widely used for cement concrete expansion joint pouring and general industrial and civil building layer caulking waterproofing, board surface coating waterproofing and underground cold storage caves, pools, tanks and pipes outside walls and other concrete and brick structural steel surfaces. And the leakage, seepage and moisture-proofing of wooden board projects. How to use highway caulking cement
When dealing with old cement concrete, it is necessary to remove the aged caulking material and debris in the joints, and keep the joints dry. The moisture content should be less than 1.
New cement concrete should be cleaned after sawing the joints.
Cut the finished polyvinyl chloride clay into small pieces on the left and right and put it into the pot, slowly heat it up and stir continuously. When melting, the temperature should be controlled at ℃, and the maximum temperature should not exceed ℃. Keep the joints filled without bubbling and yellow smoke. Thick smoke. If the above phenomenon is found, anneal immediately and speed up the stirring. The melted caulking material can be used at any time and new material can be added for continuous operation. Prolonged heating should be avoided to prevent the performance of the caulking material from changing. The melted joint material should be poured into the joint immediately with a pot. The joint material should be flush with the road surface. The excess material tip should be removed with a shovel to maintain driving comfort.
After each shutdown, the caulking material adhered to the pot should be removed to avoid affecting the quality of the new caulking material. PVC cement is a low-cost, high-performance road caulking material jointly developed by our company and its relevant scientific research units. A variety of polymer resins are combined with inorganic materials to modify the properties of asphalt, greatly improving its elastic bonding strength, aging resistance, temperature resistance and other properties. It has a wide temperature adaptability range, easy construction, long service life and excellent waterproof effect.
