Embodiment 1

[0021] A new method for producing natural rubber, the specific process steps are:

[0022] The first step of coagulation: the fresh-keeping glue collected from the rubber tree is sent to the factory by tanker, diluted with water, stirred and homogenized, and after removing impurities such as sediment and bark, it is pumped into the coagulation kettle, and coagulant and coagulant are added while stirring. Surfactants, under the action of stirring blades, make the colloidal components condense into granules in the kettle, and then let the colloidal water containing gel particles pass through a vibrating sieve to remove water;

[0023] The second step of drying: the screened rubber material enters the screw extrusion puffing dryer, using the basic principle of friction heat generation, mechanically rubs the rubber particles under the extrusion and shearing action of the screw, and the rubber material itself is mechanically rubbed However, the pressure and temperature rise rapidly...

Embodiment 2

[0026] A new method for producing natural rubber, the specific process steps are:

[0027] The first step of coagulation: using traditional technology, the fresh-keeping glue collected from rubber trees is sent to the factory by tanker, diluted with water, stirred and homogenized, after removing impurities such as sediment and bark, poured into the gel tank, and added coagulant (mainly acid coagulant) coagulation, after gelation, a large amount of water is removed through three to four double-roller extrusion dehydration processes to become thin films, and the extruded dehydrated films are crushed into small pieces with a pulverizer, screen;

[0028] The second step and the third step are the same as in Example 1.

Embodiment 3

[0030] A new method for producing natural rubber, the specific process steps are:

[0031] The first step of coagulation: the fresh-keeping glue collected from the rubber tree is sent to the factory by tanker, diluted with water, stirred and homogenized, and after removing impurities such as sediment and bark, biological gel is used to add biological strains and nutrient solution to the rubber , The gel is completed after the natural existence time, and the gel is crushed to a dryable particle size.

[0032] The second step and the third step are the same as in Example 1.

Abstract

The invention relates to a method for producing rubber. The novel method for producing natural rubber comprises the following: firstly, an agglomeration step, and secondly a drying step, in which a barrel / screw extrusion mechanism is adopted to apply force to a bulk gel of rubber to further expulse free water, and then the rubber is compressed by the relative movement of the screw and the barrel, and temperature and pressure of the rubber are raised rapidly through self mechanical friction on the basis of the friction heat generation principle; after the energy repertory of rubber arrives at a certain level, an adiabatic flash vaporization is adopted to separate water from natural rubber to accomplish the primary drying of the natural rubber; and thirdly a treatment of compensated drying to obtain the final product of rubber. The technology provided by the invention has less time consumption, colorless and semi-transparent final product and significantly improved quality. The falling-behind status from the agglomeration of emulsified rubber to drying in the prior art is changed, the labor intensity is greatly decreased, and quality of the product and production efficiency are improved.

Description

1. Technical field: [0001] The invention relates to a method for producing natural rubber. 2. Background technology: [0002] In 2006, the total output of natural rubber in the world was 9.64 million tons, and my country's output was 513,100 tons, ranking fifth in the world. The first to fourth places in front are: Thailand, Indonesia, Malaysia and India. However, since most of the rubber-producing countries are developing countries, the speed of industrialization is slow, the production process level of natural rubber is not high, and the level of automation is also very low. [0003] At present, the traditional natural rubber processing processes in various countries are as follows figure 1 Shown: The glue collected from the rubber tree is collected and sent to the rubber processing factory. Dilute with water, stir evenly, add acid to coagulate, and then remove a large amount of water through three to four double-roller extrusion dehydration processes to become a thin f...
