&Polyvinyl chloride mastic (waterproof ointment) is a kind of elasticity, strong adhesion, high heat resistance and low temperature flexibility It is a new type of building waterproofing material that has the advantages of slow aging, resistance to acid and 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 a building roof, underground moisture-proof, and waterproofing of gutters and channels, it has good use effect, simple construction and easy maintenance, and is very popular among users.
The main properties and advantages of polyvinyl chloride waterproof ointment and clay products:
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. It has good bonding and elongation properties and can adapt to changes in the roof base layer caused by thermal expansion and contraction, vibration, settlement and other reasons. Anti-aging, has certain acid, alkali and oil resistance.
& PVC cement construction scope covers joints and waterproofs: provides 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. Anti-seepage coating: Apply to dry roofs, which can replace linoleum to waterproof dry floors, mold surfaces, foundations, caverns, ground tanks and pipes. It can prevent seepage, moisture and corrosion. Paste porcelain stickers, linoleum, glass mesh, linen, etc. &. Highway expansion joints, bridge caulking, aircraft runway gaps & plastic cement construction methods:
, joint cleaning: Use a joint cleaning machine to clean the cutting joints or expansion joints that need to be filled. The depth of the joints should be appropriate. For c, 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 may affect the construction. ) Mechanical filling: Use a knife to cut the plastic clay into blocks and put them into the caulking machine. The hot melt temperature is set at ℃ and the constant temperature is ℃ (the melted clay should not be in direct contact with the electric heating rod, but should be insulated with thermal oil. Layer insulation), change the discharge hole to , and the feed valve can be closed a little smaller. The mesh number of the filter mesh should be larger than the mesh. When taking materials and cutting, be careful not to bring sand and gravel into the machine. Manual 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 melting bag (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 place a screen on the liquid surface and use a spoon to remove the material from the screen. When scooping out the glue for filling and discharging the material from the bottom of the pot, you also need to stir the material 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 bake the joint filling spoon on the fire. heat, and then use another spoon to scoop out the material and put it into the caulking spoon for filling. Never use the caulking spoon to scoop the material directly from the pot, otherwise it will seriously pollute the road surface. A dedicated person is required to melt the rubber material and be responsible for filling it in the trailer. The top is filled or discharged by filling personnel, and someone can fill and fill below at the same time (two stoves rotate melting, and can fill kilometers per hour per hour). The cement should be poured into the gaps without moisture, and the amount poured should be lower than the construction surface. (Note: When filling joints in hot weather, due to thermal expansion and contraction of the concrete slab, low pouring should be done in the morning and level pouring at noon. 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 and maintenance: On the road where the joints have been filled, the opening time depends on the traffic time. It depends on the temperature. When it is lower than ℃, it can be opened to traffic after filling it well. When it is ℃, it can be opened to traffic after 1 minute after filling. When it is above ℃, you should observe the filled rubber material and wait until the soles are no longer sticky before it can be opened to traffic
