Natural rubber microbial deodorization processing technology

Abstract

The invention discloses a natural rubber microbial deodorization processing technology, which consists of crushing, extrusion crushing, pressing ruckling, deodorization symbiotic microbial bacterial liquid cleaning, granulation, drying and packaging. The technology is characterized in that during deodorization symbiotic microbial bacterial liquid cleaning, a symbiotic flora cleaning solution well cultured in a corresponding structure of a deodorization cleaning pool is injected into the corresponding structure in the deodorization cleaning pool to conduct cleaning and deodorization on the ruckled natural rubber, so that re-processed odorless natural rubber can be finally obtained through the step. The technology can perform secondary processing deodorization treatment on already processed natural rubber so as to obtain a low odor or odorless natural rubber finished product, and especially for inferior quality natural rubber processed by small rubber processing plants in remote areas, the technology also can enhance the physical and chemical properties of the processed natural rubber by secondary processing.

Description

technical field [0001] The invention relates to the field of secondary purification and deodorization processing of natural rubber, in particular to a natural rubber microbial deodorization processing technology. Background technique [0002] The latex harvested from the rubber tree needs to be processed into various types of natural rubber. The processing technology of natural rubber is similar. The biggest difference lies in the coagulation and cleaning process of latex. Some small enterprises cannot achieve fast and high-quality processing, resulting in latex or coagulation. A large number of microorganisms grow in the block, and these microorganisms decompose the protein and sugar in the rubber to produce a large amount of odor. In the current processing technology, these odors will accompany the latex until the deep processing of natural rubber mixing. These odors Odor will affect the environment where the enterprise is located and the production environment in the work...

[0002] The latex harvested from the rubber tree needs to be processed into various types of natural rubber. The processing technology of natural rubber is similar. The biggest difference lies in the coagulation and cleaning process of latex. Some small enterprises cannot achieve fast and high-quality processing, resulting in latex or coagulation. A large number of microorganisms grow in the block, and these microorganisms decompose the protein and sugar in the rubber to produce a large amount of odor. In the current processing technology, these odors will accompany the latex until the deep processing of natural rubber mixing. These odors Odor will affect the local environment of the enterprise and the production environment in the workshop, and affect the work mood and health of the workers. The existing technology has no way to deal with this situation.

[0003] After analysis, technicians found that the odor of natural rubber mainly comes from the secondary metabolites of parasitic microorganisms in natural rubber. Two methods can solve the above problems. The first is to directly kill the microorganisms in latex or natural rubber, but in actual operation In this case, this is not feasible. Pasteurization can be used for sterilization, but the cost is too high. Of course, sealed storage can be used for preservation. The same cost is too high, and it is not feasible in actual operation. The second method is to add secondary to natural rubber. High-grade metabolites will not produce odor and the flora itself can maintain a self-sufficient microbial flora for a short time. It is the most feasible way to realize the deodorization process of natural rubber by using the theory of beneficial bacteria to drive out harmful bacteria. There is no relevant technology, especially for the method of deodorizing the odorous natural rubber that has been processed
