Rg waterproof coating sets the advantages of coils and paints. It is the most comprehensive technical index covering domestic waterproof materials, the most widely used and the comprehensive cost-effective products. The following Xiao Bian gave you an introduction to the construction process and characteristics of rg waterproof coating.
One, rg waterproof coating construction process
1, clear the grassroots
Remove impurities such as floating ash, oil stains, or loose materials from the base layer. The base surface must be firm and flat, and the uneven or cracked base surface should be leveled before construction. The base surface must be removed cleanly, without floating dust, sundries, or clear water.
2, ingredients
Each layer of ingredients is prepared by a special person, according to the mix ratio provided in the table (adjusting the amount of water according to the dry and wet conditions of the substrate and the water absorption rate of different materials). First add water to the liquid material and stir it with a hand-held electric stirrer during the mixing process. Zhongyue continued to add the powder and stir it so that it does not contain undispersed powder. The mixed paint must be used within 3-4 hours. Each layer of paint should be prepared separately.
3, brushing the bottom waterproof layer
Brush the primer layer evenly with a roller brush or a paint brush. Do not leak the bottom so that it fills the pores of the concrete or cement mortar, and form a dense film at the same time so that the lower coating film has sufficient hydration reaction time. After the coating is dry, the next procedure can only be performed.
4, details of additional layers
Relevant processing is performed on the parts that are prone to leakage.
5. Bottom vinylon cloth or fiberglass cloth
Rg waterproof coating construction process to deal with cracks in the grass roots, will not pull the film rupture, causing leakage, can use tensile strength of reinforced materials, (glass fiber cloth or vinylon cloth) so that the tensile strength of the waterproof coating is greater than The adhesive strength, together with the high elasticity and high strength of the polymer cement waterproof coating, can be achieved without any moisture. RG polymer cement composite waterproof coating can only be fully stained, and the reinforcing material must be bonded in the base layer. The two coats and one cloth are completed at one time. This is a feature of the waterproof coating film.
6, brushing, surface waterproof layer
According to the design requirements and the waterproof coating composition provided in the table, the prepared type I or II polymer cement waterproof coating is evenly painted on the surface of the base layer. Each time the amount of brushing to ≤ 0.5kg / square meter is appropriate, brushing multiple times until the design requirements of the coating film thickness requirements.
Second, rg waterproof coating features
1, water-based environmental protection products, can be used for water tank construction, does not affect the drinking water standards;
2, heat rolling resistance, weather resistance, water resistance, alkali resistance, long service life. It has good UV resistance, freeze-thaw resistance, and can be applied to the roofing of buildings.
3, good elasticity, anti-cracking ability, coating film anti-crack ability more than 3MM, suitable for waterproof under dynamic conditions;
4, cold coating construction is convenient, waterproof layer without seams, suitable for irregular base surface construction, closed wall pipe performance is good, no fire hazards.
5. Strong adhesion to common building materials, which can be bonded with PVC pipe, aluminum alloy, ceramic tile, stone, polystyrene board, asphalt, brick, metal plate, etc.;
6, can be in the wet base layer construction, regardless of the water surface, back water surface can achieve reliable waterproof function;
7, low temperature flexibility can be in the range of -5 °C --20 °C construction, apply to different climate regions throughout the country.

40Cr Material Rebar Coupler is one type of coupler made by raw material 40Cr steel. The strength can reach the tensile test of HRB335, HRB400 and HRB500 and equivalent rebar.
Rebar parallel thread splicing coupler is applied to rebar mechanical splicing for concrete construction projects, and it mainly connect HRB335, HRB400 and HRB500 hot rolled ribbed bars with diameter 12-50mm.
The strength of material 40Cr is stronger than 45C, so if customer need to connect hard rebar, we'll suggest the coupler with material 40Cr Rebar Coupler.
We have test report with 40Cr material rebar coupler, the Rebar Coupler Joint performance has reached JGJ107-2010 standard for the Grade I splicing rebar joint.
