Modified epoxy resin rubber features technical indicators using methods to detail the characteristics of modified epoxy plant anchor rubber products
1. The strength of this product is high, especially the "steel-steel" bonding shear strength and "steel-concrete" bonding high shear strength, good toughness and impact resistance.
2, anti-aging, acid and alkali resistance, shrinkage can be reduced to less than 1%, the dimensional stability of the bonding parts is good.
Application range
1. It is applied to various prefabricated components such as gluing beams and columns.
2. It is applied to the reinforcement construction of cracks of various components.
3. It is applied to the reinforcement construction of bonding steel plate and beam surface to improve load capacity.
4. It is applied to the bonding construction of building components, building materials and decoration materials such as brackets, stairs and sidewalks. After curing, the gel is applied at a maximum temperature of 80 ° C and a minimum temperature of -40 ° C.
Implementation of the standard GB50367-2006
Performance
Construction process
Surface treatment of concrete and steel plate → Selection and preparation of fixed components → Structural rubber compounding and rubberizing → Coating structural adhesive and bonding → Fixing, pressurizing, solidifying → Removing fixed pressurizing members → Quality inspection and anti-corrosion.
Construction instructions
Component A: milky white viscous paste, component B: gray-black viscous paste, density 1.7×103 kg/m3 after mixing.
1, surface treatment
(1) The concrete surface is treated so that the bonding surface is dry and free of oil, dirt and dust.
(2) Grind the concrete bonding surface, remove the 1-2mm surface layer, remove the dust, and wipe it with acetone.
(3) Derusting the surface of the bonded steel sheet.
2, with glue
(1) The filler in the glue is easy to precipitate, but does not affect the strength. Stir well before use. (The same stir bar cannot be used for components A and B when stirring)
(2) The glue is a combination of A and B. Before mixing, the glue of the components A and B should be stirred evenly, and then weighed according to the proportion of component A: component B = 4:1. In a clean container, stir well until the color is uniform.
(3) The glue should not be too much for each stirring, generally not more than 5kg.
3, paste, fix, cure
(1) Apply the glue that is evenly mixed to the bonded surface of the treated concrete and steel plate, the middle is thick, the edge is thin, and then the steel plate is bonded to a predetermined position.
(2) Immediately after the steel plate is bonded, it should be supported by clamps, bolts and other tools to be fixed, and properly pressurized, so that the glue is just extruded from the edge of the steel plate.
(3) The glue can be operated for 30-45 minutes after mixing the two components of the rubber in the room temperature.
(4) When the glue is cured at 25 ° C for 24 hours, the pressure fixing device can be removed, and it can be used after three days. When the temperature is lower than 25 ° C, the curing time should be extended accordingly.
(5) When the temperature is above 5 °C, if it is lower than 5 °C, temperature increase measures should be taken.
Packaging, storage and transportation
1. This product is packed in iron drum. The specification of small package is 4kg+1kg per set. The size of large package is 16kg+4kg per set, or the packaging specifications of each set of 64kg (4 barrels) + 16kg (1 barrel).
2. This product should be sealed and stored in a dry and clean warehouse at an ambient temperature of 0 °C - 40 °C.

Greenhouse hydroponic projects culturing ebb flood table seedbed rolling bench for propagating flowers. Ebb and Flow system is a form of hydroponics that is known for its simplicity, reliability of operation and low initial investment cost. when Pots are filled with an inert medium which does not function directly like soil that contribute nutrition to the plants, but which as a temporary reserve of water and solvent mineral nutrients in the anchors the roots. The hydroponic solution alternately floods is allowed to ebb away.
