Can AB epoxy resin be used for reinforcement planting? What is the difference between adhesive prope

Yes, there are many ways to straighten the ribs.

Are modified epoxy resin A and planting reinforcement rubber consistent with modified epoxy A and planting reinforcement glue? Is there a difference?

Dear, we're happy to answer your questions. <>

<>Modified epoxy resin A and planting reinforcement glue" and "modified epoxy A and planting reinforcement glue" are two different terms, and there is a certain difference between them. "Modified epoxy resin A and planting reinforcement glue" refers to an adhesive mixed with modified epoxy resin and planting reinforcement adhesive, which is mainly used for reinforcing and repairing concrete structures, reinforced concrete structures and other building materials. Modified epoxy resin A has excellent adhesion properties, heat resistance and chemical corrosion resistance, while planting reinforcement glue is a high-performance reinforcing material with excellent mechanical properties such as tensile resistance, bending resistance and compression resistance, which can improve the strength and stiffness of concrete structures.

"Modified epoxy A and planting reinforcement glue" is a less common term, which may refer to an adhesive similar to "modified epoxy resin A and planting reinforcement adhesive", but the specific situation needs to be determined according to the specific product name and description. To sum up, although some of the ingredients and uses in these two terms are similar, they are not completely consistent and have certain differences.

The difference between modified epoxy resin and modified ethylene glue: according to the current specifications, only organic materials are allowed to be used in the rubber and the raw materials used are specified, one is modified epoxy resin, and the other is modified vinyl ester. Epoxy resin and its mixed solidifier are insoluble in water, and can be consolidated normally in the presence of a small amount of clean water (no oil and mud dust) in the hole.

In this way, it can be said that the planting glue is not afraid of water. Therefore, some epoxy planting glue claims to be able to be constructed underwater, but because of the presence of water, it has a certain impact on the performance of the planting effect. There is no research in this area in China.

Foreign laboratory tests and field tests have shown that the tensile strength of the planting bars installed underwater has decreased by 15-20%. Another effect is the consolidation time, because of the amount of water, it is uncertain; Generally speaking, it is determined by the temperature of the substrate, but I don't think so. As for other types of planting reinforcement glue on the market, I don't know much about the inorganic, or it needs to be mixed with water when it is consolidated, so it is not afraid of water, but the flexural strength of this kind of planting reinforcement rubber (estimated to be cement-based) may be relatively poor, and it has not yet been recognized by the relevant national departments, and of course there is no standard at all.

There is another type of plant reinforcement glue, which is called methacrylate as raw material, which is a PVC material, which is relatively cheap, and this material can be slightly soluble in water, so it can not be used in an environment with water.

Reinforcement glue and epoxy resin glue are two concepts, reinforcement glue is a variety of building structures in the reinforcement, screw embedding, building structure reinforcement, reinforcement, building structure frame, shear wall reinforcement of a class of adhesive, with high bonding strength, small shrinkage in the hardening process, good temperature resistance, can be welded after burying reinforcement, good durability, weather resistance, anti-aging, medium resistance (acid, alkali, water) performance, curing toughness, impact resistance is excellent, does not contain volatile solvents, non-toxic environmental protection, A and B group distribution is relatively wide, convenient construction and other characteristics. At present, the planting reinforcement glue sold on the market includes epoxy resin type, unsaturated polyester resin type, acrylic resin type and so on.

Epoxy resin adhesive generally refers to the adhesive made with epoxy resin as the main body, and epoxy resin adhesive should generally also include epoxy resin curing agent, otherwise the glue will not cure. Due to its excellent mechanical properties, adhesion properties and anti-aging properties, it is generally used as a high-strength, structural bonding adhesive. Therefore, epoxy resin type reinforcement glue currently occupies the vast majority of the market share in the reinforcement glue market.

The composition of high-strength planting reinforcement rubber is unsaturated resin, and its strength is smaller than that of epoxy planting reinforcement glue, so high-strength planting reinforcement rubber is mostly used in places where tensile strength and strength requirements are not high.

The epoxy planting reinforcement rubber is saturated resin, acid and alkali resistance, excellent tensile resistance, hardness and strength are much higher than that of high-strength planting reinforcement glue, which can be used as a tendon for any key project.

The planting reinforcement glue has the characteristics of high bonding strength, such as pre-embedding, small shrinkage in the curing and hardening process at room temperature, good temperature resistance, welded after burying the reinforcement, good durability and weather resistance, good anti-aging, medium resistance (acid, alkali, water) resistance, excellent toughness and impact resistance after curing, no volatile solvents, non-toxic and environmental protection, wide proportion of glue distribution in group A and B, and convenient construction.

Scope of application. 1.In various building structures, steel bars and screws are planted, building structures are reinforced and reinforced, and building structure frames and shear walls are reinforced.

2.Fixation of various equipment foundations, reinforcement of railways, highways, bridges, water conservancy reconstruction and expansion projects.

3.Billboards, tunnel pipelines, elevated road acoustic panels and guardrails are secured.

How to use: Key points of planting steel bars and screw construction:

Drill holes according to regulations, clean holes with brushes and air cylinders, stir A and B components respectively, prepare planting reinforcement glue in proportion, stir and mix thoroughly, inject glue into the hole with special tools, rotate the steel bar or screw into the hole, cure, and inspect the quality.

1.According to the engineering design requirements, drill holes in the corresponding positions in the substrate (such as concrete), and the hole diameter, hole depth and steel bar diameter should be determined by professional technicians or field tests.

2.Use a special air cylinder, brush or compressed air machine to clean the dust in the borehole, it is recommended to repeat it no less than 3 times, and there should be no dust and open water in the hole.

3.The surface of the steel bar is derusted and wiped clean with acetone or alcohol.

4.Components A and B are mixed and stirred in a ratio of 2:1 until they are completely homogeneous, and injected into the borehole.

5.Rotate the rebar into the bottom of the hole to ensure that the orifice overflows and pay attention to prevent glue leakage. Whether the adhesive layer is full or not will directly affect the size of the anchoring force.

6.Avoid disturbance of the anchors during the curing process and fully cure at room temperature for 1-2 days after gelling.

7.Visually check whether the curing is normal. On-site uplift tests are required for the planting bars in important parts to check whether the anchorage force meets the design requirements. After passing the qualification, the construction of the next process can be carried out.

Epoxy resin is a general term for a class of polymers that contain more than two epoxy groups in the molecule. It is a polycondensation product of epichlorohydrin with bisphenol A or polyols. Due to the chemical activity of the epoxy group, it can be used to open the ring with a variety of compounds containing active hydrogen, solidify and cross-link to form a network structure, so it is a thermosetting resin.

Bisphenol A epoxy resin not only has the largest output and the most complete variety, but also the new modified varieties are still increasing, and the quality is constantly improving.

No one will tell you casually about the formula of planting glue, if you are willing to pay, you can find it in the next mature formula.

Summary. Reinforcement glue MT-500 is a two-component modified epoxy resin reinforcement anchorage structural adhesive, but the reinforcement adhesive is different from epoxy resin adhesive, reinforcement glue is a variety of building structures in the reinforcement, screw embedding, building structure reinforcement, reinforcement, building structure frame, shear wall reinforcement of a class of adhesives, the current common epoxy resin type, unsaturated polyester resin type, acrylic resin type, etc.

Hello, not Ou.

Reinforcement glue MT-500 is a two-component Jishan modified epoxy slippery resin reinforcement anchorage structural adhesive, but the reinforcement adhesive is different from epoxy resin glue, and the reinforcement adhesive is a kind of adhesive for reinforcement trembling and screw burial in various building structures, building structure reinforcement and reinforcement, building structure framework, shear wall reinforcement, and the common ones are epoxy resin type, unsaturated polyester resin type, acrylic resin type, etc.

Epoxy resin adhesive generally refers to the adhesive made by the epoxy resin group, in order to achieve the curing effect, it should generally also include epoxy resin curing agent, which is mostly used to make megacircle height and structural bonding adhesive, so epoxy resin planting reinforcement glue is used more in the market, such as Nanjing Mancartel reinforcement glue, adhesive steel glue, carbon fiber glue and so on.

Summary. 2. Casting.

In electrical and electronics, various electrical components and large insulating equipment are cast to seal and prevent moisture. When casting with epoxy resin, release agents must be used, such as methyl silicone rubber, silicone oil and PVC film, etc., to eliminate bubbles during the casting process, and heat to drive away bubbles; Light pouring casting; The best way to do this is to de-bubble after the resin has been cast.

The kind of planting glue production formula does not heat.

You're talking about the kind made underwater at low temperatures.

Yes. It's just that all the raw materials are added up and stirred, and there is no need to heat it.

You can refer to it.

Epoxy is good for slightly different materials, and it is generally used in engineering standards.
