Latex coagulation method
Latex is collected in liquid form for processing or it can be left to coagulate and to be collected a day after it was tapped
Reason which the collection of latex in liquid form should be done quickly
Because once exposed to the air for a few hours, the latex will start to coagulate and turn solid
Coagulation Process of Latex (1)
The negatively charged protein membrane causes rubber particles to repel each other
Coagulation Process of Latex (2)
Hydrogen ions, H+ from acid neutralise the negatively charged protein membrane
Coagulation Process of Latex (3)
Rubber particles collide with one another that causes the protein membrane to break
Coagulation Process of Latex (4)
Rubber polymers combine with one another that causes latex to coagulate
Coagulation of latex using a weak acid (1)
Acid can coagulate the latex by neutralising the negatively charged protein membrane
Coagulation of latex using a weak acid (2)
Coagulation can take place by adding a weak acid into the latex, or it can occur naturally by leaving the latex exposed to the air
