Manufacturers component polysulfide sealant polysulfide sealant construction manufacturers low-cost marketing method

Component polysulfide sealant building (paste) a technical performance, complex performance: non-pendent and self-leveling, high elongation, low modulus of two-component polysulfide sealant is fully cured rubber-like elastomer. Mix: the main agent (A): a curing agent (B) = 100: 10 (parts by weight, the standard state), depending on the season, the geographical variation in temperature. How much amount of curing agent is available to adjust the length of the applicable period, the range of variation of component B is between 10-14, when the summer construction, high temperature, two-component polysulfide sealant building on the solidification time is faster , winter construction, low temperature solidified on a little slower building in the northern two-component polysulfide sealant life of up to 140 years, in the south up to 98 years. In the factory, I have a good ratio by mass ratio, and open-minded in the box with a plastic tube, the user need not worry about the quality of proportioning use, simply open the package of the group A and B component parts Stir together put, you can use two, two-component polysulfide sealant major technical indicators 1. Appearance:. A group was divided into white uniform paste was group B is divided into 2 black uniform paste, solid content : 3 to 100%, density: 1.6 (g / cm3) 4, the mixing ratio of A: B = 100: 10 ~ 100: 14 (mass ratio) 5, ultraviolet radiation fog: no three, two-component polysulfide sealant The specific construction methods: 1, sealed surface treatment: pre-construction, the front-residual waste after construction debris clean, and then a blower or vacuum cleaner to deal with floating ash clean, if the base surface moisture to dry after application blowtorch again with a wire brush to remove baking crumbs and dust falling cement. To remove the sticky surface of the oil, dust and other debris and plastic attachments (two component polysulfide sealant stick plastic and oil, available portable cutting machine, wheel, steel brushes and other tools to work), clean and with a hair dryer blowing debris so that the exposed adhesive surface layer of solid structure, the joint surface must be completely dry, clean and free of frost. The surface of all dust and cement slurry must clear brush handle clean. Sticky surface must be absolutely guaranteed to be dry, flat, in order to prevent undesirable bonding. Rust and paint protection also need to remove the metal surface. If the structure quit, available blowtorch drying. 2, before the construction of the paste on both sides of the gap 10mm at 50mm wide masking tape to prevent the construction of the structures excess polysulfide rubber surface dirty. 3, filling the backing material: according to design requirements, to fill seams backing material, it is required to fill polyethylene foam board general design, this joint plant to produce sheet we specifically building and two-component polysulfide sealing supporting the use of glue. 4, brushing primer solution: design requires the use of a primer solution works, or long-term flooding parts of the seal, to be sticky brushing primer liquid on the surface, dry film (primer reprovision). 5, the preparation of sealant: the inside barrel of white polysulfide rubber (A component) and a bag of black hardener (B component), stir until no color so far. Specifically, the following: the two-component polysulfide sealant A, B two groups were poured on a glass plate or tile (tile requires optimum 60 cm square), according to the instructions given mixing ratio, the mixing ratio of A : B = 100: 10 ~ 100: 14 (mass ratio), mixing the two components can be used, according to the factory I have been with a good ratio of quality, and in a separate box with a plastic tube placed points, the user no need to worry about the quality of proportioning use, simply open the package component A and B together into the stirring evenly, you can use artificial mixing time of not less than nine minutes, stirring with a portable electric drill at least 6 minutes, with mechanical stirring method is appropriate, mixing time should be long not short, so as to avoid uneven mixing causes partial curing is not complete and reach the waterproof seal. Regardless machine mixed or hand mixed, should achieve uniform color without color. Mixing should be to prevent mixing of air bubbles, a good two-component polysulfide sealant formulation should be used within two hours, or slowly thickening caused by construction difficulties and reduce performance, therefore, we should pay attention to how much distribution, or because with more the used up and wasted. 6, two-component polysulfide sealant coated with gray knife the prepared sealant layer on both sides of the joint before applying, then two-component polysulfide sealant joints embedded in the intermediate channel and reaches a predetermined thickness, For when a narrow seam and special parts for construction difficult gray knife can be marinated two-component polysulfide sealant construction glue gun is loaded and then driven into the construction site. The operation should try to prevent entrainment of air bubbles into the sealant. For difficult bonding material parts to ensure adhesion, preferably with special primer is applied after first brushing sealant (primer reprovision). Should prevent the inclusion of air bubbles, remember that the glue should compaction, fill seal to prevent air bubbles mixed. Stir well component polysulfide sealant must be finished within two hours use, because the 2 kid paste colloid chemical composition under the action began long solidification. (Dry time ≤24 hours, 7 days Party Irrigation can test, 28 days to reach full performance.) 7, after construction, the gap on both sides of the protective tape can be removed within 24 hours to avoid water will rain. 8, check the construction quality: after completion of construction to deal with joint sealant conduct a comprehensive inspection, such as tainted scratch, uneven, sagging, etc. should be promptly repaired neatly. Component polysulfide sealant dry time of 24 hours, 7 days, but up to 80 percent intensity, so two-component polysulfide sealant is not fully cured before, we need to protect, prevent water intrusion and reduced performance, closed water tests must be carried out at the construction seven days.
