What are the common methods of keeping binders in the binder classification?

Adhesives classification What? Adhesive for very many, life is more commonly used as a chemical coating, mainly in order to fit the tile or wallpaper use. If you want to buy adhesives, a good brand can ensure the effectiveness of the adhesive. Each adhesive has a certain storage period. After this period, the viscosity of the adhesive will be affected and the desired effect cannot be achieved. Therefore, the storage method of the adhesive is very important, and the There are many factors, if you do not pay attention, it is easy to reduce the storage period, so now let us take a look at the common storage methods of common adhesives it!

Adhesive type

1, source of material points

1 natural adhesive

Taken in nature, including: starch, dextrin, shellac, hide glue and other bio-adhesive; also includes mineral adhesives such as asphalt.

2 artificial adhesive

Artificially produced materials include inorganic binders such as water glass and organic binders such as synthetic resins.

2, using the characteristics of points

1 water-soluble adhesive

Water as a solvent binder, mainly: starch, dextrin, carboxymethyl cellulose and so on.

2 hot melt adhesive

Used by melting after heating, it is a solid adhesive. General thermoplastic resins are available, such as: polyurethanes, polyacrylates, and the like.

3 Solvent type adhesive

Soluble in a solvent binder. Such as: shellac, butyl rubber and so on.

4 emulsion adhesive

More suspended in water, such as: vinyl acetate, chlorinated rubber and so on.

5 Solvent-free liquid adhesive

At room temperature was a viscous liquid, such as: epoxy resin. According to characteristics: permanent and removability. It has a variety of recipes for different face materials and occasions. It is the most important component in self-adhesive material technology and is the key to label application technology.

3, according to raw materials

1MS modified silane

The end of the modified silane polymer is methoxysilane, the world's only supplier of modified silane raw materials. Based on this, through continuous innovation, it produces a series of sealants for construction, industry, automotive transportation, civil use, etc. Adhesives.

2 polyurethane

The full name "polyurethane" is an organic polyisocyanate or polyisocyanate with dihydroxy or polyhydroxy compound polyaddition.

3 Silicone

Commonly known as: "silicone oil or dimethyl silicone oil", molecular formula: (CH3) 3SiO (CH3) 2SiOnSi (CH3) 3, a series of silicone oxide polymers, is a series of different molecular weight polydimethylsiloxane, viscosity Increases with increasing molecular weight.

4, according to packaging materials

1 paper-based material adhesive

Including: starch paste, water glass, casein, etc.

2 plastic adhesive

Including: SBR, nitrocellulose and other solvent-based adhesives such as ethylene-acrylic copolymer water-soluble adhesives; vinyl acetate resin, and other emulsion adhesives; polystyrene, polyacrylate and other thermoplastic resins Hot-melt adhesives, etc.

3 Wood adhesive

Including: bone glue, casein, blood glue and other animal glue; including: phenolic resin, urea-formaldehyde resin glue and other synthetic resin glue; also includes soybean gum and other plant glue.

Adhesives, Adhesives Non-metallic materials that combine the solid surface with another surface due to surface bonding and internal forces.

5, by use

1 Industrial adhesives

For building materials and packaging, to achieve the connection of objects and things.

2 Adhesives for agriculture and forestry

It is used for slope greening or soil structure improvement to make the soil form aggregate structure and achieve the effect of soil conservation. At the same time, it enhances the permeability of the soil, prevents soil loss, preserves soil and fertilizers, and relieves evaporation of soil moisture, allowing better crop growth.

Common storage methods for common adhesives

1 Epoxy adhesive: Stored in a ventilated, dry environment for a period of six months to one year.

2 phenolic resin adhesive: Packed in a closed container, stored in a cool place, the period is six months to one year.

3 Polyisocyanate glue solution: Put it in a brown bottle and store it in a dark place. And strict waterproof points to enter, otherwise it will happen polymerization deterioration;

4Urea-formaldehyde resin adhesive: Storage temperature should be low. Add 5% of methanol to improve storage stability.

5 Neoprene adhesive: Store containers at room temperature, away from fire. Storage period is from 3 to 6 months.

6a-cyanoacrylate adhesive: Stored in a sealed, dry, dark place for 1 year.

7 Anaerobic adhesive: Stored in a cool, dark place, the storage period is six months, cut iron containers, can not be filled.

8SGA adhesive: sealed storage, placed in a cool, dry place, the period is six months to one year.

9 Polyester vinyl ester emulsion: glass and ceramic containers are used for packaging. The storage temperature is 5 to 30c and the storage period is 1 year.

10 hot melt adhesive: Stored under light and heat insulation.

11 Inorganic adhesives: Store sealed to prevent moisture absorption.

Editor's summary: The above is a brief introduction to the common methods for the storage of common adhesives in adhesives. Adhesives are commonly used chemical coatings in daily life, mainly to fit tiles or wallpapers. in use. In the above section, some famous brands of adhesives were introduced. Only the use of adhesives from famous brands is truly effective. Interested friends can purchase the brands mentioned above. help.
