Specifications: kg Density: kg Shelf life: months& & Common names: plastic clay, C clay, plastic ointment, waterproof ointment, caulking clay, PVC filler Sealing material PVC cement is a new type of building waterproofing material that has the advantages of elasticity, strong adhesion, high heat resistance, good low temperature flexibility, slow aging, acid and alkali corrosion resistance, 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 +°C &°C. It has a service life of more than ten years without aging. , has good bonding and elongation properties, and is adaptable to changes in the roof base layer due to thermal expansion and contraction, vibration, settlement and other reasons. , Anti-aging, and has certain acid and alkali resistance and oil resistance. & Construction scope
, Covering joints and waterproofing: supplying various new and old concrete roof panels, wall panels, floors, aqueducts, water pipes, overpasses, dams, tanks, driveways, underground tunnels, basements and other components. Sealing and waterproofing of structures can play a role in repairing seams and preventing leaks. 2. Anti-seepage coating: Applying to dry roofs can replace linoleum waterproofing to dry floors, mold surfaces, foundations, caverns, ground tanks and pipes. It can prevent seepage, moisture and corrosion. , highways, bridges and cracks and leaks. & Construction method
& 1. Preparation before construction: & &, Construction tools: seam cleaning machinery (seam cutting machine, hair dryer), seam filling machine (manual, mechanical), scraper, etc., construction materials: polychloride Vinyl putty, cleaning agent. & 2. Construction: & Seam cleaning: Use a seam cleaning machine to clean the cutting seams or expansion joints that need to be filled. The depth of the seam cleaning should be c, and use a hair dryer to blow away the floating dust. There should be no floating dust on the joint wall& & Heating and filling: (Before heating and melting, the inner film bag must be torn off to prevent flakes from being formed during 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 ℃, and the constant temperature is at ℃ (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 , and the feed valve can be turned down, and the filter The mesh size of the mesh should be larger than the mesh size. Be careful not to bring sand and gravel into the machine when picking up materials and cutting. & Artificial filling: Use a pot with a thermal oil layer to heat the melt. The heating temperature (heated with a slow 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 have a fusible bag (kg) , simmer and keep at constant temperature for use. When half of the melted material has been used, you can add unmelted clay. There is no need to wait until it is used up before adding it. When taking material from the liquid surface, you can put a screen on the liquid surface, and then use a spoon to remove the material from the liquid surface. 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 soluble material from aging if it is not used for a long time. For caulking when the temperature is low, first place the caulking spoon in the furnace. Heat it over a fire, then use another spoon to scoop out the material and put it into a caulking spoon for filling. Do not use a caulking spoon to scoop material directly from the pot, otherwise it will seriously pollute the road surface. A dedicated person is required to melt the rubber and be responsible for filling it. The trailer is loaded or unloaded by the filling personnel, and someone can fill the trailer below at the same time (two stoves rotate the melting, and can fill kilometers per hour per day). &. The cement should be poured into the gaps without moisture, and the pouring amount should be lower than the construction surface. (Note: When filling joints in hot weather, due to the thermal expansion and contraction of the concrete slab, it should be poured low in the morning and flat at noon. Irrigation, 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 scrape off the glue on the road surface. Road joint filling maintenance: On the pavement that has been filled with joints, open it to traffic. The time depends on the temperature. When it is below ℃, it can be opened to traffic after filling it. When it is ℃, it can be opened to traffic within minutes after it is filled. When it is above ℃, you should observe the filled rubber material and wait until the soles are non-stick before it can be opened to traffic. Leak repair: It often happens when filling joints. If there is leakage of irrigation or the leakage of poured materials, the leakage of irrigation should be re-irrigated in time& & Cleaning tools: After the construction is completed, the mixer and caulking machine should be cleaned with solvent, and the remaining residue should be scraped off the hot melt pot. Glue material to prevent the remaining glue from coking the next time it is melted. & 3. Precautions: &. Because when the concrete is wet, it will affect the adhesion of the product. Avoid construction on rainy days or in gaps with water. Therefore, you should know the weather forecast before construction. Do not construct in rainy weather&. Because of the product Contains flammable tar. Be careful not to overflow when preheating and melting to prevent fire. When clearing the gap, the walls on both sides of the gap must be clean and dry, otherwise the bonding fastness between the glue and the gap will be affected and it will be easy to deglue. According to the "Highway According to the requirements of "Technical Specifications for Construction of Cement Concrete Pavement", the depth of glue filling should be, the shallowest is not less than.
