How to extract rubber from plants, and from what plants is rubber extracted

Cut a strip of mulch on the bark of the tree, let the emulsion containing rubber seep out, collect the latex, leave it at room temperature for two days, put it in water and cook it, and take it out!

When the skin of the rubber tree is cut, a milky white sap will flow out, called latex, and the latex is condensed, washed, molded, and dried to obtain natural rubber.

Draw a spiral opening on the rubber tree (not too long), connect a joint at the lower end of the crossing, and put a rubber bucket under the joint.

Rubber is divided into natural rubber and synthetic rubber. Natural rubber is made from rubber trees, rubber grass and other plants after extracting gum, mainly in the clover rubber tree, when the skin of this rubber tree is cut, it will flow out milky white juice, called latex, latex by condensation, washing, molding, drying to obtain natural rubber. Synthetic rubber is made by artificial synthesis method, and different kinds of rubber can be synthesized from different raw materials (monomers).

The milk from the clover rubber tree is rubber, and this tree is generally harvested in 10 years, so you can go back to plant it on your land.

It's mainly a three-leaf rubber tree, but the rubber seedlings are planted, and it takes 7 years before they can be tapped, so it needs to be 7 years later.

Early rubber was a material made of elasticity, insulation, impermeability to water and air after processing from latex from rubber trees, rubber grass and other plants. Highly elastic polymer compounds. It is divided into two types: natural rubber and synthetic rubber.

Natural rubber is made from rubber trees, rubber grass and other plants after extracting gum; Synthetic rubber is obtained by polymerization of various monomers.

Synthetic rubber is a polymer made of oil and natural gas as raw materials and diolefins and olefins as monomers, which began to be produced at the beginning of the 20th century and has developed rapidly since the 40s. Synthetic rubber is generally not as comprehensive as natural rubber in terms of performance, but it has high elasticity, insulation, air tightness, oil resistance, high temperature or low temperature resistance and other properties, so it is widely used in industry and agriculture, national defense, transportation and daily life. It is a necessary material for the manufacture of aircraft, automobiles, tractors, harvesters, water conservancy and irrigation machinery, medical equipment, etc.

Raw rubber refining is a process that transforms raw rubber from a strong elastic state to a soft and easy to process plastic state through mechanical stress, heat, oxygen or the addition of certain chemical reagents.

The purpose of raw rubber refining is to reduce its elasticity, increase plasticity, and obtain appropriate fluidity to meet the requirements of various processing processes such as mixing, sub-derivation, extrusion, molding, vulcanization, and glue paste manufacturing, sponge glue manufacturing, etc.

Mastering the appropriate plasticity of plastic refining is crucial to the processing of rubber products and the quality of finished products. On the premise of meeting the requirements of the processing process, the plasticity should be reduced as much as possible. With the emergence of constant viscosity rubber and low viscosity rubber, some rubber no longer needs to be molded and directly mixed.

No, rubber is divided into natural rubber and synthetic rubber.

Natural rubber is extracted from plants and then processed to make these plants such as clover rubber tree, eucommia ulmoides, root gum grass, etc.; In recent years, scientists have extracted natural rubber from dandelions. Because rubber is widely used, from aerospace to daily necessities; Bridges, embankments, automobiles, high-speed railways, etc. will use rubber, precisely because it should be extensive, natural rubber can not meet some special performance requirements, so synthetic rubber has been developed.

Synthetic rubber is the process of extracting monomers from petrochemical products, then refining, repolymerizing, and preferably processing. Synthetic rubber has many properties that natural rubber does not have, such as oil resistance, acid and alkali resistance.

It is a tree in Southeast and Western Asia.

Natural rubber: An industrial raw material extracted from the milk secreted by the clover rubber tree, which is mainly used in the manufacture of tires. The main production areas are Thailand, Indonesia and Malaysia in Southeast Asia.

Natural rubber comes from rubber trees, rubber grass and other plants; Synthetic rubber comes from the synthesis of oil and gas.

The basic production process of rubber with general natural rubber (also known as "raw rubber", different from rubber) as raw material includes: plasticizing, mixing, calendering, and vulcanization.

1. Plasticizing is the process of degrading the long-chain molecules of raw rubber to form plasticity.

There are two methods of raw rubber plastic refining: mechanical plastic refining and thermoplastic refining. Mechanical plasticizing is to shorten the long chain and change from a highly elastic state to a malleable state through the mechanical extrusion and friction of the plasticizer at a temperature that is not too high. Thermoplastic refining is to introduce hot compressed air into the raw rubber, and under the action of heat and oxygen, the long chain degradation becomes shorter and plasticity is obtained.

2. Mixing is a process in which the plasticized raw rubber is mixed with the compounding agent, placed in the rubber mixer, and the compounding agent is completely and uniformly dispersed in the raw rubber through mechanical mixing.

3. Vulcanization is the process of converting plastic rubber into elastic rubber through the network structure of vulcanizing agents (such as sulfur, vulcanization accelerators, etc.) and semi-finished products of raw rubber that are cross-linked into a solid structure. The vulcanized elastic rubber is called vulcanized rubber, also known as soft rubber, commonly known as "rubber".

4. Auxiliary measures can be added to the production process to obtain rubber with special use performance.
