Introduction of several types of industrial glue

Industrial glue is an application classification of adhesives. Industrially used to combine uniform or heterogeneous surfaces with adhesives. The adhesive has the characteristics of continuous stress distribution, light weight or good sealing performance, and low temperature in most processes. Generally speaking, industrial glue has the characteristics of high strength, high applicable temperature, large choice of viscosity, low price, and easy production.

Industrial glue classification

Acrylic Adhesive

Acrylic adhesives are structural adhesives with a wide range of adhesive properties, including most types of plastics in which slightly treated rather than treated metal. It can be divided into two-component catalytic curing, one-component UV curing or thermal curing. Good flexibility, very good and weatherproof. Fast curing.

Anaerobic Glue

One-component adhesive/sealant, curing only in the absence of air. Locking and fixing threaded cylindrical shape, pipe thread sealing, sealing plane.

Instant Glue

The one-component adhesive cures immediately upon contact with the metal surface. Most substrates have good adhesion and high strength. It can have different viscosities, curing speeds, void filling capabilities and surface compatibility.

Epoxy Glue

It can be one or two components, heated and solidified at room temperature. It has high bonding strength to most substrates, and sometimes even exceeds the strength of the substrate itself. Epoxy resin is very hard, chemically resistant and weather resistant. Can be used for thermal conductivity and conductive epoxy resin.

Hot Melt Glue

The thermoplastic material, after being melted in the slurry machine, wets the surface of the substrate and solidifies to form an adhesive when cooled. Fast curing is not a real structural adhesive, but a variety of bonding substrates.

Mono-polyurethane adhesive or two-component, with good adhesion to treated thermoplastic and thermosetting plastic surfaces. It has good flexibility and durability. There are three curing methods: catalytic curing, thermal curing and curing, and solvent evaporation. Generally slow curing.

Silica Glue

One-component silicone adhesives/sealants cure by moisture to form a hard solid. It has good weather resistance, abrasion resistance, moisture resistance and chemical resistance. Operating temperature -76 to 600 degrees Fahrenheit (-24 degrees Celsius -315 degrees Celsius)

UV Curing Adhesive

One-component, solvent-free, UV and visible curing adhesives can be used for bonding, coating, sealing, and sealing. It can solidify within a few seconds after being exposed to ultraviolet or visible light.

Structural Glue

The structural adhesive has high strength (compressive strength>65MPa, steel positive tensile strength>30MPa, shear strength>18MPa), can withstand large loads, is resistant to aging, fatigue, and corrosion, and has stable performance within the expected life. Adhesive suitable for strong structural parts.

High temperature Glue

High temperature plastics are binders for high temperature resistant inorganic nano composite materials made from the condensation of inorganic nano materials. It has strong adhesion, non-corrosiveness, and can be used for metal substrates at high temperatures. Good adhesion and corrosion resistance, long service life.

Repair Glue

Repair glue, also known as repair glue, is mainly used to repair the bonding of metals, ceramics and other materials. A common application is to repair castings, which can meet normal mechanical performance requirements. According to the different repair materials, it is mainly divided into: casting repair agent, iron repair agent, steel repair agent, aluminum repair agent, copper repair agent and so on. Take high-quality viscose industrial repair agent as an example: repair agent also includes rubber repair agent. Medicament, emergency repair agent, oil surface repair agent, wear-resistant repair agent, corrosion-resistant repair agent, etc.

Glue Uses

Electronics industry application industry

Electronics and electrical industry; adhesives are used in the electrical/electronics industry and have a wide range of applications, from microcircuit positioning to the bonding of large motor coils. Once the adhesive fails, the consequences are very serious. The computer will stop running, the city will darken, and the missile will not be disarmed. In addition to mechanical fastening, electrical adhesives also require electrical, insulation, vibration reduction, sealing, and floor protection.

Epoxy resin is the most widely used in the electrical/electronic industry because of its versatility, excellent adhesion, wide adaptability, ease of use, good electrical properties and aging resistance. The invention is suitable for applications requiring flexibility, wide temperature range, high frequency, high temperature and air pollution. Hot melt adhesive glue can be used under conditions that require fast assembly, low strength and low operating temperature.

Shipbuilding industry

Plastic glue is widely used in many places on ships for bonding and sealing. It has become an indispensable material to simplify the production process, shorten the shipbuilding cycle, improve reliability and safety, reduce labor intensity, and play an important role. Adhesive glue is used to assemble boats, whether it is FRP, wood or metal structures. In addition to the conventional adhesives for structural adhesives and rubber components, river, lake, and sea containers also have special environments, and a large number of glue adhesives/sealants. Liquid polysulfide sealant is used to fill the structure. Stitch the seams to solve the problem of seam sealing wood. Sealants are widely used to seal seams on ship decks, hatches, windows and various oils, water lines and cables.

Civil Engineering

Pre-consolidated concrete reinforcement structures have been widely used in buildings such as bridges, large open-air stadiums, underwater tunnels, and lighthouse foundations. In 1963, the bridges near Paris were joined together for the first time with epoxy resin instead of mortar.

Aerospace Industry

Adhesives are widely used in manned and unmanned spacecraft. Use adhesives to manufacture parts, components, or fix parts to spacecraft.

Aviation Industry

Synthetic adhesives have been used in aircraft for decades, and their application has made significant changes in the structure of aircraft, resulting in high strength, light structure, fatigue and long life. Reliable and efficient aircraft production. #? The machinery industry led by the aviation industry has become the main driving force for the development of modern adhesives. The number of single-machine adhesives usually marks the level of the national aircraft manufacturing process. The successful application of adhesives can promote advanced heat-resistant and high-strength composite materials, such as carbon fiber and boron fiber, which can be used in the aviation industry to further improve aircraft structures.

Construction Industry

In the construction industry, it is mainly used for construction and decoration glue, making many construction engineering components, such as cork plywood, laminate, laminated cardboard and some similar parts, vinyl flooring, carpet, tile paste, in recent years, construction work, Adhesives have been used to replace mechanical reinforcement. This type of structure is called an adhesive, so that a strong bond can be achieved and the joint has poor thick or thin adhesion. At present, there are two main problems with pressure-sensitive adhesive structures: First, the lack of proper temperature control for the bonding process; other process equipment does not require proper mechanical reinforcement.

Automotive Industry

The application of adhesives in the automotive industry (including automobiles, trucks, motorcycles and related vehicles) has simple process, reliable performance, and low cost. It can be used to fix or seal metals, plastics, fabrics, glass and rubber. The structural connection of the installation surface.

The main function of sealant (sealant and gasket) for cars and trucks is to isolate air, dust and water to reduce corrosion or improve comfort. In many cases, they can also be used as positioning adhesives. Many applications on modern car bodies are invisible. In fact, the use of low-viscosity rubber sealant is more suitable for all gold and metal body connections than spot welding. Polyethylene hot melt adhesive can be used in areas that are difficult to solve after assembly. Usually, polyethylene sealant is used to replace the welding seam of the precursor joint, and then the joint is covered, which cannot withstand large bending, expansion and contraction. The sealant has good adhesion, sufficient viscosity, no sagging, and good weather resistance. They must undergo severe salt spray exposure and multiple freeze-thaw cycles. Epoxy sealant is replacing traditional lead solder on the car body.
