Coating process: polymer composite self-adhesive waterproof roll product construction process

Core tip: polymer composite self-adhesive waterproof roll series products, compared with the same type of waterproof roll at home and abroad, have the advantages of high strength, strong adhesion and good sealing However, due to its high strength and high tension, the corners are easy to rise, or the wrinkled parts are uplifted; due to its strong adhesive force, the initial adhesive pressure is uneven, and it is difficult to flatten later; due to its good sealing performance, the air displacement is not complete when paving, and the water vapor on the base surface is easy to form "steam pressure" and blister The above advantages of polymer composite self-adhesive waterproof roll, if the construction operation is improper, it will become a disadvantage Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Coating home news: polymer composite self-adhesive waterproof roll series products, compared with the same type of waterproof roll at home and abroad, have the advantages of high strength, strong adhesion and good sealing However, due to its high strength and high tension, the corners are easy to rise, or the wrinkled parts are uplifted; due to its strong adhesive force, the initial adhesive pressure is uneven, and it is difficult to flatten later; due to its good sealing performance, the air displacement is not complete when paving, and the water vapor on the base surface is easy to form "steam pressure" and blister The above advantages of polymer composite self-adhesive waterproof roll, if the construction operation is improper, it will become a disadvantage "Waterproof engineering, design is the foundation, material is the foundation and construction is the key" In order to make the polymer composite self-adhesive waterproof roll give full play to its unique function and prevent the application of the material from being affected due to improper construction operation, the advantages and disadvantages of the finished product are specially described above Construction process flow: base acceptance → base treatment → fence setting → base treatment agent brushing (only limited to the positive paving method) → construction personnel replacing casual shoes → detail treatment → coiled material paving (including reverse paving and positive paving) → coiled material closing treatment → closed water test 1 Base acceptance: the base course of the coiled material waterproof layer shall be firm, the base surface shall be clean and flat, without hollowing, loosening, sanding and peeling; the internal and external corners of the base course shall be made into an arc shape Inspection method: observe and inspect the acceptance records of concealed works 2 Base course treatment: if the base course cannot meet the construction requirements, the raised part of the base course shall be leveled with steel chisel first, and then leveled with polymer mortar; if the base course surface is pockmarked surface or sanding, the base surface attachment shall be brushed with steel wire brush first, then cleaned with vacuum cleaner, wetted with water, and then leveled with polymer mortar when there is no open water on the surface Mix proportion of polymer mortar: 425 × cement, fine sand, water, latex = 1:1.5:0.3:0.15, and it can be scraped and plastered after mixing evenly 3 Brush the base treatment agent (only limited to the positive laying method): the function of this process is to close the base moisture and transfer the adhesion between the coiled material and the base surface Pour the special supporting material pc-10 primer into the container, add it according to the scale proportion (pc-10 and tap water = 1:1) and mix it evenly, and then brush the compound evenly on the surface of the base layer with roller brush, no leakage is allowed If the base surface after painting is polluted for some reason, the product shall be painted on it again 4 Replacement of construction personnel's casual shoes: after the base treatment agent is painted, the construction personnel who pave the coiled material shall replace the flat sole casual shoes; when the supervisor or visitors really need to step on the coiled material, they shall obey the command of the site management personnel and tie the plastic shoe cover It is forbidden to wear spiked shoes on the construction surface 5 Detail treatment: details refer to the rainwater inlet, top pipe (or wall pipe), construction joint and internal and external corners The gutter inlet and outlet pipe shall be provided with 160 mm wide double-sided self-adhesive tape as the turning cone; the construction joint shall be provided with 160 mm wide self-adhesive tape for additional; the internal and external corners shall be provided with 250 mm x 250 mm double-sided self-adhesive tape for additional 6 Coiled material paving: (1) reverse paving method: firstly, the datum line shall be marked on the base surface, then the coiled material shall be pre paved along the datum line, and then the isolation membrane at the overlapping part shall be uncovered, and the scraper shall be used to push and blow the air while paving; the butt joint shall be used at the transverse joint Cover a 160mm wide double-sided self-adhesive strip along the middle line of butt joint and compact For the waterproof of the base plate with small amount of reinforcement and small amount of welding joint, remove the coiled material isolation membrane before binding the reinforcement, and spread a layer of cement powder (subject to no foot sticking, not too much) to operate on it; for the waterproof of the base plate with large amount of reinforcement or large amount of welding joint, remove the coiled material isolation membrane and make a mortar protective layer on it after the waterproof layer acceptance, with a thickness of 20-30mm (2) Positive laying method: when the coil is laid in a positive way, a reference line shall be marked with a red line box first, and then the coil shall be laid in advance The method of drawing the isolation membrane at the bottom shall be adopted, and the scraper shall be used to push it while drawing, until all the air is removed, compacted and compacted, and no exposed scraping is allowed The longitudinal lap edge should be scraped and pressed again after the coiled material is paved and pasted, and then compacted with a rubber hammer The butt joint method is adopted for the transverse joint, i.e a 160mm wide double-sided self-adhesive strip is set at the bottom of the joint of two coils; the upper surface of the transverse joint is additionally sealed with 30mm wide double-sided self-adhesive strip 7 Coil closing treatment: generally, the coil should adopt groove closing, that is, first put the coil into the groove (accounting for 80% of the groove) and then fix it with steel batten; seal with 30mm wide sealing strip and seal with 1:2.0 cement mortar If polymer mortar is used to seal the joint, it can be fixed without steel batten and directly sealed with polymer mortar 8 Closed water test: when the waterproof layer is inspected by closed water method, the rainwater inlet and other parts shall be plugged first, and the average water injection shall be 10cm / 24h to observe whether there is leakage Problems and solutions on the construction site: 1 After the base surface is coated with cold primer, due to human trampling and other reasons, a layer of primer shall be painted before the coiled material is laid 2 There is blister after the coiled material is paved: it is caused by incomplete exhaust during construction The middle of the hollow drum shall be cut through a small cross cut and dried until the base surface is dry Then a piece of double-sided self adhesive shall be plugged into the "hole", and the cut part shall be flattened and hammered with a rubber hammer If the weather is cold (below 10 ℃), it can be heated and compacted by hot air welding machine 3 Lap edge and wing edge: use double-sided self adhesive to cover and compact 4 Roll end flange: after the roll is fixed with steel batten, the edge of the roll is easy to appear flange, which needs to be sealed with tire free double-sided adhesive, i.e half of the double-sided self adhesive is stuck on the wall and half on the batten 5 After the coil is laid, it is damaged: the non-woven fabric at the damaged part shall be cut off with a knife, and then a layer of double-sided self-adhesive shall be added on it, and a coil larger than the wound shall be welded on the double-sided self-adhesive Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
