What are gums used for? What are the functions and effects of gum?

Uses of gums:

Gum arabic is the most widely used gum in industry, often used in food, medicine, cosmetics, pigments, inks, printing, textiles, etc., and is also used to prevent leakage on the inner wall of oil depots.

Astragalus gum is mainly used in food, medicine and cosmetics.

Peach gum is mainly used for watercolor pigments and printing.

Larch arabinogalactan is mainly used in medicine, food, etc.

Gum is a pesticide-free, antibiotic-free natural product, often exported to foreign countries to make health care products.

The flavonoids contained in gum are also good for the human body and have a certain effect of propolis.

In particular, poplar gum is a better substitute for propolis, and the function of poplar gum has a lot of similarities with propolis, and gum also has a strong health care effect.

The uses are roughly as follows:

1.Gum arabic. It is mainly the secretion of the gum arabic tree.

Light yellow to yellowish brown solid, brittle and shiny. The viscosity of the solution is low, and it can be prepared into a solution with a concentration of more than 50%, and its adhesive properties have nothing to do with viscosity. The world produces 50,000 tons per year, 90% of which is produced in Sudan.

It is the most widely used gum in industry, often used in food, medicine, cosmetics, pigments, ink, printing, textiles, etc., and is also used to prevent leakage on the inner wall of oil depots.

2.Astragalus gum. It is the secretion of gum yarrow (Astragalus gummifera) and the like. It has the highest viscosity of its solution in gums, and is mainly used in food, medicine and cosmetics.

3.Peach gum. It is prepared by hydrolysis of peach secretions, mainly used for watercolor pigments and printing, and can also be edible, with beauty and beauty.

4.Rubber. Latex from rubber trees, rubber grass and other plants is extracted and processed to make materials with elasticity, insulation, impermeability to water and air. Highly elastic polymer compound with a wide range of applications.

Gum is an important industrial raw material, which can be used as an emulsifier, thickener and pharmaceutical excipient, and has a wide range of uses in pharmaceutical, printing and dyeing, food, papermaking, petroleum, mining and metallurgy, coatings, etc. There are many types of plant gums, such as gum arabic, astragalus gum, peach gum, sycamore gum, etc.

1) Gum arabic is native to Africa, extracted from the secretions of gum arabic branches after injury, and is used as an ingredient for the production of glue, ink, pharmaceuticals and confectionery, and is used as an emulsifier, sizing agent and thickener in industry.

2) Astragalus gum is produced in Asia Minor region leguminous Astragalus several plant stem secretions, Astragalus gum is often used in the printing and dyeing industry as a thickener for printing and sizing, also used as an emulsifier, pharmaceutical excipient, binder, and used in food candy, ink manufacturing and leather finishing, cosmetics, etc.

3) Peach gum is the gum secreted by the branches of peach trees, mountain peaches, plums, apricots, cherries, etc. after injury or microbial infection, and is the earliest application of gum in China, which can be used as an adhesive and an excipient for the production of tablets.

4) Sycamore gum has high viscosity in cold water, the viscosity decreases when the water temperature is higher than 20, the water is greatly inactive after boiling for 2 minutes, and adding a small amount of strong dielectric can also make it lose its viscosity. Sycamore gum is widely used in food, textile, medicine, cosmetics, cigarettes and other industries.

Properties and uses of gums.

Gum is insoluble in volatile solvents (alcohol, turpentine, etc.). Starch and similar water-soluble binders are generally grouped with gums because they have similar properties and functions. For example, a category of dextrin is called Britannia gum, which is used on the back of the so-called sticker as a glue.

The flavonoids contained in the gum are also good for the human body, and have a certain effect of propolis, especially poplar gum, which is a better substitute for propolis, and the function of poplar gum has a lot of acquaintances with propolis, and gum also has a strong health care effect.

The use of resin glue is that it can be used for polyester, paper, plastic, metal signs, crystal buttons, crystal bottle caps, crystal wooden combs, crystal handicrafts and other decorations, and resin glue is divided into soft rubber and hard rubber.

Resin usually refers to an organic polymer that has a softening or melting range after being heated, and has a tendency to flow under the action of external force when softening, and is solid, semi-solid, and sometimes liquid at room temperature. Broadly speaking, any polymer compound that can be used as a raw material for the processing of plastic products is called a resin.

Resin glue is to use the viscous characteristics of the resin itself to make it more viscous through physical or chemical means to meet some industrial requirements to make various types of glue.

Uses of resin glue:

1. Resin glue can be used not only to make grease products, but also to make resin lenses, harm to people: contact with too much unprocessed resin glue will cause people's allergic reaction, so it is best to wear gloves.

2. The use of resin glue is that it can be used for polyester, paper, plastic, metal signs, crystal buttons, crystal bottle caps, crystal wooden combs, crystal handicrafts and other decorations, and resin glue is divided into soft rubber and hard rubber.

3. The use of epoxy resin glue: it is the main material for the manufacture of FRP. After forming, it has the characteristics of insulation, corrosion resistance, heat resistance and so on.

It is widely used in electrical appliances, shipbuilding, automobiles and other fields. Epoxy adhesive has strong adhesion. It also has the characteristics of insulation, corrosion resistance, heat resistance and so on.

It's just that its texture is relatively brittle, and it can be bonded to hard objects, and soft things such as shoes can be bonded.

Resin glues are commonly used in industry to bond different materials.

Resin glue is an adhesive product used to bond different materials, usually used in industry, such as wood, bamboo, and plywood.

and other materials of bonding, resin glue itself is more viscous, after some physical, chemical and other treatments are more viscous, in the industry often according to specific requirements to make different types of glue, for example, epoxy resin hard rubber and soft rubber is a more common resin glue.

Resin glue can be used not only to make grease products, but also to make resin lenses, resin glue can also be used for polyester, paper, plastic, metal signs, crystal buttons, crystal bottle caps, crystal wood combs, crystal handicrafts and other decorations, and resin glue is divided into soft and hard rubber.

Advantages of resin glue

1. The cohesive force of resin glue is relatively high, and the internal structure is relatively dense. Relative to phenolic resins.

Does not contain polyester, epoxy glue.

It has high mechanical properties and is more robust to use. And after a long time, it is not easy to fall off, ensuring its quality.

2. The bonding function contained in resin glue is also very powerful. In the inside of the epoxy resin glue, it contains strong cohesive strength, so it can exert strong adhesion in the process of bonding items, so as to ensure that the items will not fall off for a long period of time, and act as a structural adhesive.

to use. 3. For resin glue, the curing shrinkage contained in it is only about 1% to 2%, which is one of the smaller types in other resins, and the linear expansion of epoxy resin glue is also relatively small, so its internal stress is small, and the probability of cracking in the later stage is also very small to ensure normal use.
