>&Polyvinyl chloride clay (plastic clay)
>Specification: kg
>Density: kg
>Shelf life: months
>
>Common name: plastic clay , clay, plastic grease, waterproof grease, caulking clay, PVC caulking material PVC clay is a kind of elasticity, strong adhesion, high heat resistance, good low temperature flexibility, slow aging, acid resistance It is a new type of building waterproofing material that is resistant to alkali corrosion, suitable for hot construction and can be used cold. It is improved and developed on the basis of traditional clay. Can replace asphalt linoleum or other waterproofing materials. As building roofs, underground moisture-proofing, waterproofing of gutters and channels, road caulking, etc., it has good results. It is simple to construct and easy to repair, and is very popular among users.
>Performance and advantages
>
>It has good heat resistance and cold resistance. It does not drip in hot weather and does not stick to your feet. It is flexible in cold winter and can be used in a temperature range of +℃℃. It has a service life of more than ten years without aging.
>. It has good bonding and elongation properties and is adaptable to changes in the roof base layer caused by thermal expansion and contraction, vibration, settlement and other reasons.
>, aging resistance, certain acid, alkali and oil resistance.
>
>Construction scope
>
>, Covering joints and waterproofing: supplying various new and old concrete roof panels, wall panels, floors, aqueducts, water pipes, overpasses, dykes, Pool tanks, driveways, tunnels, basements and other components. Sealing and waterproofing of structures can play a role in repairing seams and preventing leaks.
> Anti-seepage coating: Applying to dry roofs can replace linoleum waterproofing to paint dry floors, mold surfaces, foundations, caverns, ground tanks and pipes to prevent seepage, moisture and corrosion.
>Special for filling cracks and leaks in highways and bridges.
>
>Construction methods
>
>&1. Preparation before construction
>
>Construction tools: seam cleaning machinery (seam cutting machine, Hair dryer), caulking machine (manual, mechanical), scraper, etc.
>
>Construction materials: polyvinyl chloride clay, cleaning agent.
>
>2. Construction
>
>&. Seam clearing: Use a seam cleaning machine to clean the cutting seams or expansion joints that need to be filled. The depth of the seam cleaning It is advisable to use a hair dryer to blow away the floating dust, and there should be no floating dust on the seam wall
>
>
>&, heating and filling: (Before heating and melting, the inner film bag must be torn off Clean to prevent flakes from melting, which will affect the construction)
>
>Mechanical filling: Use a knife to cut the clay into blocks and put them into the caulking machine. The hot melt temperature is set at ℃. The constant temperature is ℃ (the melted clay cannot be in direct contact with the electric heating rod, but should be insulated with a layer of thermal oil). Change the discharge hole to d, and the feed valve can be closed a little smaller. The mesh number of the filter mesh should be Larger than the mesh, be careful not to bring sand and gravel into the machine when picking up and cutting.
>Manual filling: Use a pot with a heat-conducting oil layer for hot melting. The heating temperature (heated with a gentle fire) is preferably ℃. In order to prevent the temperature from being too high, coking and deterioration, it must be stirred up and down frequently. Each pot can be filled with fusible bags. (kg), simmer and keep at constant temperature for use. When half of the melted material has been used, unmelted clay can be added. There is no need to wait until it is used up before adding. When taking material from the liquid surface, you can put a screen on the liquid surface, and then Use a spoon to scoop out the clay from the screen for filling. When discharging the material from the bottom of the pot, the material must also be stirred up and down to prevent the upper melted material from aging if it is not used for a long time. When filling joints when the temperature is low, first fill the joints. Heat the spoon on the fire, then use another spoon to scoop out the material and put it into the caulking spoon for filling. Do not use the caulking spoon to scoop the material directly from the pot, otherwise it will seriously pollute the road surface and require a dedicated person to melt the rubber. It is also responsible for loading or unloading materials for filling personnel on the trailer. Someone can fill the tank below at the same time (two stoves rotate melting, and can fill kilometers per hour).
>
> The cement should be poured into the gaps without moisture, and the amount of pouring should be lower than the construction surface. (Note: When filling joints in hot weather, the concrete slab will expand due to thermal expansion and contraction. , so it should be low irrigation in the morning, flat irrigation at noon, and high irrigation in the afternoon)
>
>&. Cleaning: When filling joints, glue is often poured onto the flat surface accidentally. At this time, use a scraper to clean the road surface. Scrape off the glue on the surface
>
>&. Road joint filling and maintenance: On the pavement where the joints have been filled, the opening time depends on the temperature. When the temperature is lower than ℃, it can be opened to traffic. Minutes can be opened to traffic. When the temperature is above ℃, you should observe the filled rubber material and wait until the soles are non-stick before opening to traffic. If there is leakage, the leakage should be refilled in time
>
>&. Cleaning tools: After the construction is completed, the mixer and caulking machine should be cleaned with solvent, and the inside of the hot melt pot should be scraped. The remaining glue material will prevent the remaining glue from coking during the next melting.
>
>3. Precautions
>
> Since the adhesion of the product will be affected when the concrete is wet, construction should be avoided on rainy days or in gaps with water. Therefore, you must know the weather forecast before construction. Do not perform construction in rainy weather
>
>. Because the product contains flammable tar, be careful not to overflow when preheating and melting to prevent fire
>
>. When cleaning joints, the walls on both sides of the gap must be clean and dry, otherwise the bonding fastness of the glue and the gap will be affected and it will be easy to debond
>
>. According to "Highway Cement Concrete Pavement Construction Technology" According to the requirements of the "Specification", the depth of glue filling should be, the shallowest is not less than.
