History and Common Problems of Building Adhesives During Use

History and Common Problems of Construction Adhesives During Use
Building adhesives are one of the earliest adhesives for human use. Since the beginning of human housing construction, we have used sticky
The materials used to bond the building materials are clay, lime, gypsum and other primary machine adhesives.
Since the appearance of hydraulic cement in the 18th century, cement has become the main adhesive for construction, and it still occupies a major position. With the development of science and technology, many kinds of polymer materials have appeared successively in the 20th century, and they have been more and more widely used in the construction industry. Architectural adhesives are one of the important uses of polymer materials. Building adhesives are not only used in the production of building materials, but also in the construction of the application of a wide range of flags. Using adhesives in buildings not only
To improve the quality of the building, increase the aesthetic comfort, and improve the construction process.
Nowadays from general civil buildings to skyscrapers, from bridges to tunnels, dams, various types of buildings
Engineering has been inseparable from the bonding and sealing techniques. Based on organic polymer construction adhesives according to the use of poly
The types of compounds can be divided into three basic types: thermosetting, mature plastic, and inert. Architectural adhesives used in recent years
Instead of using one type of polymer alone, channels are blended, copolymerized, etc.
Better performance, mixed type. The construction adhesives and sealants mentioned in this Municipality mainly refer to the aforementioned work.
Process adhesives.

The following problems are generally encountered in construction projects. The solution to these problems is the use of adhesives.
1. Decoration of interior walls and ceilings of buildings;
2, indoor floor decoration and laying;
3 , exterior wall decoration of buildings ;
4, glass curtain wall manufacturing and doors and windows sealed;
5, the prefabrication of houses and components;
6, roof, roof, walls, underground works waterproof, leak proof;
7, mortar modification and concrete repair;
8, bridge reinforcement;
9, underground tunnel joints sealed.

Adhesive tools are suitable for industries with liquid, glue.

Adhesive tools are suitable for industries with liquid, glue.
The viscose tools are mainly divided into manual viscose tools, pneumatic viscose tools, and electric viscose tools suitable for various liquids and oils (including inks, crystal glue, hypoxic glue, silicon glue, solder paste, AB glue, etc. Epoxy PV, PU, red plastic, yellow plastic, white plastic, lubricants, etc.). Has been widely used in electronic products, buttons, LED, LCD, switches, home appliances, batteries, transformers, golf balls, coils, cameras, motors, medical equipment, watches, keyboards, mice and so on.

Piston glue storage tank and ordinary glue storage tank for liquids with different fluidity

Piston glue storage tank and ordinary glue storage tank for liquids with different fluidity

Piston glue storage tank is suitable for medium and high viscosity liquids, while ordinary glue storage tank is suitable for high viscosity liquids.
If it is a high-viscosity liquid, we can choose peristaltic pump, gear pump, pressure pump, and screw pump for liquid transport.

50ML AB glue gun POM material

1, 50ML AB glue gun push POM material is not easy to break, glue gun care ABS material more comfortable. When it is used, it only needs to be filled with AB glue barrel with glue, and then the mixing nozzle can be connected. The operation is very simple, and the body is small, lightweight and durable, which meets the needs of manual dispensing.
2, AB glue gun total capacity of 50ml, portable AB glue gun for a variety of AB glue a small amount of automatic mixing, bit by bit, can completely solve the problem of uneven mixing of two-component adhesive products applied to all two-liquid mixed materials, such as: ring Gas resin, silica gel with A / B plastic and so on.

Dispensing valve pneumatic and electric Triaxial dispensers

Pneumatic:the material cylinder and the cylinder are connected to the main body of the dispensing valve is made up of three parts: cylinder, valve body and material cylinder. The air cylinder and valve body are separated by advanced sealing material to prevent glue from invading the cylinder. The pneumatic body is used for the movement of the solenoid valve to drive the center rod up and down, and the up and down movement of the center rod is used to open and close the glue According to the different ways of opening and closing, it can be divided into: plunger-type valve, ejector-type valve, lifting-type valve, spray-dispensing valve, and jet-dispensing valve is the highest accuracy; the switching mode is Different, and the applicable fluid is also On the other hand, the suction-suction valve adopts an upward movement and closes the glue structure,so that the glue is sucked and broken at the same time and the residual glue on the remaining needle is reduced, so that the dispensing does not produce the phenomenon of leaking or drawing. The valve body is anodized by aluminum alloy. The sealing material adopts The latest PTFE material. The contact colloid part is corrosion-resistant material.

Electric: mainly divided into a gear pump and a peristaltic pump including the pump body and drive part, with the stator, easy to install. Adopt stator and rotor structure design, good sealing performance. The rotor and stator pairs form a self-sealing structure that is Easy to replace. Through the directional rotation of the rotor in the stator cavity, the media conveying function is realized. The conveying process does not have any influence on the properties of the medium. At the same time through the motor reversal, easy to achieve Media suction function, ensure the media and materials clean, no leakage, no pollution!

Triaxial dispensers:

The main function to achieve three-axis movement

1.Functions of drawing points, lines, surfaces, circle, consecutive interpolation of irregular curves and three axis linkage enables to pot any irregular workpieces;

2.software can use achieve three-axis movement that has functions of regional array,translation,rotation and computation,etc;

3.The size of glue, speed of glue spread, dispensing time, time of halting dispensing can be set parameters. With this method, glue outflow is quite stable without leaking and dripping;

4.Fully automatic operation with integration of metering,potting,encapsulation function.

5.Mixing on demand and potting at the same time to save glue.

6.Dual barrels to store A,B glue separately, which prevents gel in a long time.

7.Optional dynamic or static mixing mode ensure full mixing, and mixing ratio can be regulated from 100:100 to 100:10.

8.Especial control system without impaction from air pressure,which avoids the phenomenon of nonuniformity, drawing and bubble in the potting process.

9.Height-adjusting device of Z-axis enables to work for workpieces of which the height are different; 12.Automatic alarming by up /low level materials sensors to avoid short of material.

10.Optional functions of stirring, heating and deaeration,fit for various potting /dispensing process.
