How is dry rubber content measured?

The dry rubber content of field latex is determined roughly by means of the hydrometer known as the ‘Metrolac’, which is an instantaneous method.

How is DRC calculated in latex?

DRC was determined by adding 4% acetic acid to concentrated latex, then let it for coagulate. After the coagulation remove the serum and measure the rubber mass and calculate DRC. TSC was determined by adding distilled water to a known latex sample and swirling it.

What is total solid content of latex?

Total solids content (TSC) of latex is the mass percentage of the solid material (both suspended and dissolved), measured by evaporating a known mass of latex to dryness at a temperature of 100 C–105 C. crumbling, and drying.

What is Metrolac meter?

Metrolac meter and chart is used to calculate dry rubber content. Metrolac chart is a table. Metrolac meter is sinked in latex and read the measurement(metrolac reading). Then we refer the metrolac chart according to the metrolac reading to find dry rubber content.

What is dry rubber?

Dry natural rubber – This is rubber produced by the dry natural rubber (DNR) process, which involves the use of coagulated natural latex in the form of dried or milled sheets. Products are formed from dry natural rubber by compression molding, extrusion, or by converting the sheets into a solution for dipping.

How do you calculate solid content?

% Solids = (Net weight of the dry specimen / Net weight of the original specimen) x 100.

How do you make tiny rubber dry?

The Tiny Dry Rubber is a component added by Industrial Foregoing. It is created in a Latex Processing Unit using 1000 mB of Water, 75 Latex and 200 Tesla. It can be used to create Dry Rubber.

How do you get dry rubber in FTB?

First off, making plastic requires you to smelt a dry rubber. You get dry rubber by crafting nine tiny dry rubber. You get tiny dry rubber by pumping latex (fluid) and water into a Latex Processing Unit (which also requires power). And you get the latex by placing a wood log in front of a Tree Fluid Extractor.

What is the solid content?

“Solids content” refers to the amount of base product (proportion of non-volatile material) left in the adhesive once the volatile solvent has vaporized. Generally speaking, the higher the solids content in an adhesive, the further it will go, providing more adhesive coverage on the materials being bonded.
