Abstract: UN METODO PARA PRODUCIR UN PRODUCTO MOLDEADO DE GOMA LATEX NATURAL DESPROTEINIZADA CAPAZ DE REDUCIR EL CONTENIDO DE ALERGENOS EN EL MATERIAL DE GOMA LATEX NATURAL A NIVELES SUFICIENTES PARA EVITAR QUE EL LATEX SEA PERJUDICIAL PARA EL CUERPO HUMANO SIN DISMINUIR LOS RENDIMIENTOS DEL PRODUCTO NI DETERIORAR LA FORMABILIDAD DEL LATEX. EN EL PRESENTE METODO, LA ELIMINACION POR LAVADO DEL CONTENIDO NO-GOMA SE LLEVA A CABO DESPUES DE LA DESCOMPOSICION DE PROTEINAS, PREVULCANIZACION Y MOLDEADO. COMO LIQUIDO LIMPIADOR PARA LA ELIMINACION POR LAVADO SE UTILIZA UNA DISOLUCION ACUOSA ALCALINA, AMONIACO, AGUA CON UN CONTENIDO DE CLORO LIBRE DE 0,005 A 0,02 % EN PESO O UNA MEZCLA LIQUIDA ALCOHOL-AGUA CON UN CONTENIDO DE ALCOHOL DE UN 5 A 80 % EN PESO. EL METODO PUEDE APLICARSE ADECUADAMENTE PARA LA PRODUCCION DE PRODUCTOS DE GOMA NATURAL TALES COMO GUANTES DE GOMA, PRESERVATIVOS, CATETERES, MATERIALES DE ESPUMA DE GOMA Y SIMILARES.

Abstract: A fertilizer absorption accelerator composition is provided which is capable of accelerating the absorption in a plant of such fertilizer components as calcium, nitrogen, phosphorus, and potassium. The composition is obtained by combining a fertilizer component with a surfactant and a heptonic acid or a salt thereof and is applied to the plant as sprayed to the surface of leaves thereof.

Abstract: A method for producing a formed product of deproteinized natural rubber latex capable of reducing a content of an allergen in a natural rubber latex material to a level sufficient to keep the latex from being harmful to the human body without decreasing yields of the product and deteriorating formability of the latex. In the method, cleaning removal of a non-rubber content is carried out after each of protein decomposition, prevulcanization and forming. An aqueous alkali solution, ammonia, water containing free chlorine in an amount of 0.005 to 0.02% by weight or alcohol-water mixed liquid containing alcohol in an amount of 5 to 80% by weight is used as cleaning liquid for the cleaning removal. The method is suitably applied to production of a natural rubber product such as a rubber glove, a condom, a catheter, a foam rubber material and the like.

Abstract: A process for producing raw rubber from a deproteinized natural rubber is disclosed, which comprises coagulating rubber particles in the deproteinized natural rubber latex by: (1) adding a nonionic surfactant having a cloud point of from 20 to 100 DEG C and a molecular weight of 300 or more to the deproteinized natural rubber latex and heating the latex to a temperature not lower than the cloud point of the nonionic surfactant; or (2) adding a coagulation assistant selected from the group consisting of: (a) an anionic surfactant, (b) an amphoteric surfactant, (c) a nonionic surfactant, (d) a nonionic or amphoteric oligomer or polymer, and (e) an anionic oligomer or polymer, to the deproteinized natural rubber latex; and then recovering the coagulated rubber particles. According to the process of the present invention, raw rubber containing substantially no metal ion can be produced with a high efficiency.
