JPS6168130A - Method for controlling amount of water-soluble material to be dissolved into water - Google Patents

Abstract

PURPOSE:To control the amt. of a water-soluble material to be dissolved into water by mixing the water-soluble material and a water-insoluble material, heating, melting, and solidifying the mixture, and controlling the amt. by the degree of roughness and fineness of a spongy structure formed by the water-insoluble material. CONSTITUTION:A water-soluble material such as polyethylene glycol and a water- insoluble material such as stearic acid are mixed, and the mixture is heated, melted, and solidified. The water-soluble material is included in the water-insoluble material to form a spongy structure. When the structure is placed in water, the water-soluble material is dissolved in water little by little for a long period, the water-insoluble material is kept unchanged, and remains as a dense spongy structure keeping the initial shape of the solid material. According to experiment, when 50g solid material is used, the contained water-soluble material dissolves almost completely into water in 20 days with 5% stearic acid, in 30 days with 10%, and in about 40 days with 20%. The period for dissolution increases with increasing weight of the solid material. With <=5% stearic acid, the spongy structure is slightly brittle, and tends to collapse in water. Accordingly, >=7% stearic acid is preferably used for retaining the original form.

しくみに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanism for controlling and adjusting the amount of aqueous solution itself dissolved in water by adding a non-aqueous substance to the aqueous solution at a certain rate.

水溶物を水中にて、少量ずつ長期間にわたって水溶させ

たり、また消泡剤、防疫剤等の使用には長期一定の水溶
持続困難なため、その都度添加するなど手間もかかり、
取扱いでも面倒な場合が多い。There are many needs to dissolve aqueous substances in water in small amounts over a long period of time. Conventionally, for example, when looking at toilet antifouling agents, adjusting the amount of aqueous solutions requires the use of containers with special structures, and when using antifoaming agents and epidemic prevention agents, it is difficult to maintain a constant solubility in water over a long period of time. , it takes time and effort to add it each time,
It is often difficult to handle.

本発明は水溶物を包含して一体となっている非水溶物が
つくる緻密な海綿状構造により、水溶物の水溶を制御す

いるものである。The present invention uses a dense spongy structure formed by a non-aqueous material that is integrated with a water-soluble material to control the dissolution of the water-soluble material, and also adjusts the density and density of the spongy structure and the amount of water dissolved. It is something.

したがって、このしくみを用いれば水溶物自体が水溶量
を調節するため、容器等は不用となシ、手間もかからず
取扱いにも便利であシ、多方面への利用が可能である。Therefore, if this mechanism is used, the aqueous solution itself adjusts the amount of the aqueous solution, so there is no need for a container, etc., and it is convenient to handle without requiring much time and effort, and can be used in a wide variety of fields.

リン酸はそのまま残り、頭初の固形物の形のまま緻密な
海綿状構造として残る。In this case, stearic acid, which is an oil and fat, encapsulates polyethylene glycol to create a spongy structure. When placed in water, polyethylene glycol gradually dissolves in water over a long period of time. When all the aqueous substances are dissolved in water and dried, the stearic acid remains as it is, remaining as a dense spongy structure in the initial solid form.

適当である。According to experiments, in the case of a solid material with a total weight of 50 g, almost all of the aqueous content is dissolved in water after 20 days with 5% stearic acid, 60 days with 10% stearic acid, and 40 days with 20% stearic acid. Naturally, as the weight of the solid increases, the period of dissolution in water increases. Furthermore, if the stearic acid content is less than 5%, the spongy structure becomes somewhat brittle and tends to lose its shape in water. 7% or more is appropriate for maintaining the original shape.

When an experiment was conducted by placing 0g in a toilet water tank, blue water flowed into the toilet bowl for about a month, the lubricating properties of polyethylene glycol and the cleaning power of surfactants reduced the amount of dirt in the toilet bowl, and the incense of the fragrance reduced the amount of dirt in the toilet bowl. Odors caused by backflow of water are also eliminated. Note that when a surfactant is added, the amount of water solubility tends to increase.

軟化して固形化しにくくなる。Moreover, if 10 to 20% of an antifoaming agent, an epidemic prevention agent, etc. are added to a base of stearic acid or polyethylene glycol, it will dissolve in water little by little while maintaining its original shape, but if more than 60% is added, it will soften and become difficult to solidify.

造のできるものであれば、同種の効果が期待できる。In this example, stearic acid, an oil compound, was used as an appropriate water-insoluble substance under the conditions of melting point (70°C), non-hydrophilicity, pure substance, etc., but other oils and fats, such as paraffin wax, etc. Although the mixing ratio of inorganic substances such as baladichloropenzole is different from that of stearic acid, the same type of effect can be expected as long as it forms a spongy structure.

内の水溶量を定め得ること等である。As described above, by utilizing the spongy structure formed by non-aqueous substances, it is possible to adjust and control the amount of water-soluble substances dissolved in water. To summarize the mechanism of the control method, the non-aqueous substance has a spongy structure, the mixing ratio of the non-aqueous substance can influence the degree of density of the spongy structure, and therefore the amount of water dissolved can be adjusted, and the substance itself Since the amount of water dissolved is controlled, special containers are not required, and the amount of water dissolved in a fixed period of time can be determined depending on the total amount of the substance and the mixing ratio of non-aqueous substances. be.
