In the cold winter of natural latex will degenerate?
In the cold winter of natural latex will degenerate? Latex tube industry has been the focus of discussion, Xiaobian for reasons we compiled under the natural latex in winter metamorphism.
Natural latex is a milky white liquid flow, look like milk. Shenzhen latex tube products must be raw materials, without any material of fresh latex, rubber hydrocarbon accounts for only 20%-40% of the total, the rest is a small amount of non rubber components and water. Non rubber components in protein, lipid,carbohydrate and inorganic components, they part and rubber particles into a composite structure, a part of dissolved in whey or the formation of non rubberparticles.
Under normal circumstances, the low temperature environment in winter will make the latex from liquid to solid, the influence of the use of latex. And low temperature environment for the emulsion density, viscosity, surface tension andpH have certain influence. And has a great influence on the stability of emulsionin the pH value of it. Fresh latex is neutral and slightly alkaline inclination, pH value 7~7.2. After several hours to ten hours, due to the effect of bacteria andenzymes in latex, pH decreases and becomes acidic, resulting in solidification.Therefore, often adding ammonia or other alkali, the pH increased to 10~10.5,so as to be able to long-term preservation. In the environment of low temperature, is likely to change the latex pH value, cause the latex modification.
