What are the classification of adhesives? There are many kinds of adhesives. They are a kind of chemical coating commonly used in life, mainly for fitting tiles or wallpaper. If you want to buy Adhesives, a good brand can ensure the use effect of adhesives. Every adhesive has a certain storage period. After this period, the viscosity of the adhesive will be affected and cannot achieve the desired effect. Therefore, the storage method of the adhesive is very important, and there are many influencing factors. If you don't pay attention, it is easy to reduce the storage period. Now let's take a look at the specific storage methods of common adhesives

what are the classifications of adhesives? There are many kinds of adhesives, which are commonly used in daily life. They are mainly used for fitting tiles or wallpaper. If you want to buy Adhesives, a good brand can ensure the use effect of adhesives. Every adhesive has a certain storage period. After this period, the viscosity of the adhesive will be affected and cannot achieve the desired effect. Therefore, the storage method of the adhesive is very important, and there are many influencing factors. If you don't pay attention, it is easy to reduce the storage period. Now let's take a look at the specific storage methods of common adhesives

types of adhesives

1. Material sources are divided into

① natural adhesives

are taken from nature, including biological adhesives such as starch, dextrin, shellac, leather glue, etc; It also includes mineral adhesives such as asphalt

② artificial adhesives

artificially manufactured substances include inorganic adhesives such as water glass and organic adhesives such as synthetic resin

2. Service characteristics

① water soluble adhesives

adhesives with water as solvent, mainly including starch, dextrin, carboxymethyl cellulose, etc

② hot melt adhesive

it is used after heating and melting. It is a solid adhesive. General thermoplastic resins are available, such as polyurethane, polyacrylate, etc

③ solvent based adhesive

adhesive dissolved in a certain solvent. Such as shellac, butyl rubber, etc

④ lotion adhesives

are mostly suspended in water, such as vinyl acetate resin, chlorinated rubber, etc

⑤ solvent free liquid adhesive

is viscous liquid at room temperature, such as epoxy resin. By characteristics: permanent and removable. It has a variety of formulas, suitable for different surface materials and occasions. It is the most important component of self-adhesive material technology and the key of label application technology

3. According to raw materials

① MS modified silane

the end of the modified silane polymer is methoxysilane. It is the only supplier of modified silane raw materials in the world. On this basis, through continuous innovation, it produces a series of sealants and adhesives for construction, industry, automobile transportation, civil use and so on

② polyurethane

full name “ Polyurethane ”, It is formed by adding organic diisocyanate or polyisocyanate with dihydroxy or polyhydroxy compounds

③ silicone

commonly known as: “ Silicone oil or dimethyl silicone oil ”, Molecular formula: (CH3) 3sio (CH3) 2sionsi (CH3) 3, a polymer of organosilicon oxide, is a series of polydimethylsiloxanes with different molecular weights, and the viscosity increases with the increase of molecular weight

4. According to the packaging materials

① paper based materials adhesives

include: starch paste, sodium silicate, casein, etc

② plastic adhesives

include: styrene butadiene rubber, cellulose nitrate and other solvent adhesives ethylene — Water soluble adhesives such as acrylic copolymer; Vinyl acetate resin, and other lotion adhesives; Hot melt adhesives composed of polystyrene, polyacrylate and other thermoplastic resins

③ wood adhesives

include: bone glue, casein, blood glue and other animal glue; Including: phenolic resin glue, urea formaldehyde resin glue and other synthetic resin glue; It also includes vegetable gum such as bean gum

adhesives, non-metallic materials that combine solid surfaces with another surface due to surface bonding and internal force

5. According to the purpose,

① industrial adhesives

are used in building materials and packaging to achieve the connection between things

② agricultural and forestry adhesives

are used for slope greening or soil structure improvement, so that the soil forms a granular structure and achieves the effect of moisture conservation. At the same time, enhance the permeability of soil, prevent soil loss, protect soil and fertilizer, alleviate soil water evaporation, and let crops grow better

specific storage methods of common adhesives

① epoxy resin adhesives: store in a ventilated and dry environment for a period of half a year to one year

② phenolic resin adhesive: put it in a closed container and store it in a cool place for a period of half a year to one year

③ polyisocyanate glue solution: put it in a brown bottle and store it away from light and at low temperature. And strictly prevent moisture from entering, otherwise polymerization and deterioration will occur

④ urea formaldehyde resin adhesive: storage temperature should be low Add 5% methanol to improve storage stability

⑤ neoprene adhesive: container, store at room temperature, away from fire source The storage period is 3 ~ 6 months

⑥ a-cyanoacrylate adhesive: store in a sealed, dry and dark place for 1 year

⑦ anaerobic glue: store it in a cool, dark place for half a year. Cut it into iron containers and do not fill it

⑧ SGA adhesive: store it in a sealed, cool and dry place for a period of half a year to one year

⑨ polyvinyl polyester lotion: it should be packaged in glass and ceramic containers, with a storage temperature of 5 ~ 30C and a storage period of 1 year

⑩ hot melt adhesive: store away from light and heat

? Inorganic adhesive: sealed storage to prevent moisture absorption

editor's summary: the above is the introduction of the relevant knowledge about the classification of adhesives and the specific storage methods of common adhesives. Adhesives are a commonly used chemical coating used in life, mainly for fitting tiles or wallpaper. The above mainly introduces some well-known brands of adhesives. Only the adhesives of well-known brands are really effective when used. Interested friends can buy the brands introduced above, which will also be helpful for paving tiles in the future
