Natural emulsion ion and storage
The natural latex from rubber tree, extract of eucommia ulmoides plants, TKS. Of latex, best quality, most of them hevea. Storage in the bark of phloem laticifer in rubber latex, cut open the bark, milk of latex by tube itself and the surrounding of parenchyma cell turgor pressure effect, is allowed to flow out continuously. Early in the morning is one of the largest when the turgor pressure effect, so tapping are selected in the morning, general requirements completed 6 or 7 o 'clock.
Natural latex outflow from the tree soon enzyme activities and bacteria, especially under the action of oxygen and light, become more active, to make the protein, carbohydrate, ester latex decomposition to generate organic acid or corruption, such as material, and in charge colloidal particles cause coagulation. The presence of metal salts in latex react with protective layer on the one hand, on the other hand also can promote the activation of enzymes and bacteria, of which most affect magnesium ions, it may force latex coagulation. For these reasons, usually for a period of time after tapping, latex can produce natural coagulation. So to use preservatives.
Save the agent's role is to kill the bacteria in the latex, or inhibit enzyme activity, inhibit the further breeding of bacteria, or increase the electric charge of colloidal particles, improve factor potential protect the stability of latex. The modern development of the low ammonia latex is to use a small amount of ammonia and some chemicals and used to save the revertex.
