The invention relates to the technical field related to the production of natural rubber, in particular to a formula of a natural rubber latex biological coagulant and processing equipment thereof.
Background
For nearly a century, the problem with natural rubber processing has been the prevention and acceleration of coagulation in natural rubber latex. The common measure for preventing the putrefaction, deterioration and solidification of natural rubber latex is to add ammonia, formaldehyde or sodium sulfite into the rubber latex, and the addition amount is determined according to the time for which the latex needs to be kept in a liquid state. The most common preservative for concentrated latex is ammonia, which can be used alone or in combination with a second preservative such as sodium pentachlorophenolate, boric acid, zinc diethyl sulfamate, etc. It is generally necessary to use an acid for coagulation after the addition of ammonia, usually formic acid. Formic acid is a liquid with strong irritation, easily harms human bodies, animals and plants, and destroys the ecological environment.
