Total Solid Content Of Natural Rubber Latex

To compute the carbon content of latex produced by a rubber tree the dry rubber content drc or total solid content tsc can be used as discussed in literature jayanthy sankaranarayanan.

Total solid content of natural rubber latex.

The solid content of the latex has a dielectric constant in the range of 2 0 to 2 5 and the loss tangent is between 0 01 to 0 05. 1 1 this standard prescribes a method for determination of total solid content of natural rubber latex concentrates whi8ch contains preservative agent and which has been prepared by some type of concentration process and also for determination of total solids content of synthetic rubber lattices. However accurate determination of the percentage dry rubber content drc and the percentage total solid content ts of natural rubber latex is important for the export certification of. This means that the attenuation due to water is large while that caused by dry rubber is small.

The total solid content refers to the content of all solid matter in the latex after removal of water and volatile components expressed as a percentage. The total solids content values obtained by the microwave oven method are compared with the values obtained by heating in a conventional convection oven. The basic components of fresh hevea other than water about 500 0 80 are 18 to 45 dry rubber content drc and approximately 2 to 5 non rubber constituens or total solid content of about 20 to 50 chin 1979 fig. The suitability of using the microwave oven for the rapid determination of total solids content tsc of natural rubber latex has been established over a broad range of dry rubber content drc.

Therefore the higher the total solid content the lowerthe attenuation ofthe microwave power. These methods are not necessarily suitable for latex from natural sources other than the hevea brasiliensis for vulcanized latex for compounded latex or for artificial. Total solid content and dry rubber content generally have a difference this value is called the total dry poor used to explain latex non volatile non rubber content. This international standard specifies methods for the determination of the total solids content of natural rubber field and concentrated latices and synthetic rubber latex.

These methods are not necessarily suitable for latex from natural sources other than the hevea brasiliensis for vulcanized latex for compounded latex or for artificial dispersions of. The quality ofthe hevea rubber latex. Iso 124 2014 specifies methods for the determination of the total solids content of natural rubber field and concentrated latices and synthetic rubber latex.
