Problems solved by technology

[0008] Second, it is difficult to avoid lumps and hard cores in the colloid.
[0010] The third is that it is necessary to increase the device, which is inconvenient to operate
[0011] Filtration transfer requires the addition of filtration devices, power for suction filtration / press filtration, addition of batching tanks and other equipment, and additional operating steps
[0012] Fourth, affect product quality
[0013] If there are a large number of agglomerates and hard cores being filtered out, it will lead to a deviation in the dosage of the thickener, which will affect the viscosity of the final product and may affect the quality assurance of the product within the validity period.

Embodiment 1

[0032] Embodiment 1 Traditional process and process contrast of the present invention-operation method, preparation time and result contrast

[0033] 3% xanthan gum-10% glycerin-water solution thickening system preparation

[0034] 1. Experimental method

[0035] The traditional craft preparation method is:

[0036] (1) Add 100g of glycerin into 870g of purified water, stir and mix;

[0037] (2) Sprinkle 30g of xanthan gum into it slowly while stirring, and continue to stir until the hydration is completely uniform and there are no visible particles and lumps, and no hard core.

[0038] In step (2), it is advisable to choose a preparation tank with a larger diameter to increase the spread area of ​​the polymer substance on the liquid surface and increase its chance of contact with the solvent. The entire dissolving process takes 2-3 hours, and stirring should be continued during this period And pay attention to remove the xanthan gum adhering to the container wall and the s...

Abstract

The invention provides a method for efficiently preparing a high molecular material thickening system. Before a solvent is used for dissolving or swelling a high molecular thickening substance, the high molecular thickening substance and another medium are fully premixed to obtain a premix, wherein the medium is a substance which can be mixed and dissolved with the solvent of a high molecular material but can not swell or dissolve the high molecular thickening substance. The method has the advantages of being less in time consumption, reduced in energy consumption, good in product quality, capable of avoiding occurrence of agglomerates and hard cores in colloids, free of filtration, convenient to operate, capable of realizing expanded production easily, and adaptive to operation demands of industrialization production.

Description

technical field [0001] The invention relates to a method for efficiently preparing a polymer material thickening system, which is suitable for preparing various viscous liquids and semi-solid products containing polymer materials. Background technique [0002] A large part of the various products involved in medicine, food and cosmetics are suspension products, and their physical form is often viscous liquid or semi-solid with certain fluidity. In order to stabilize the physical stability of the formulation system, the particle size of the active ingredient and other indicators, and ensure that the quality of the product does not change within the validity period, it is usually necessary to add a thickener as a suspending agent to the formulation. [0003] Suspension-type pharmaceutical preparations can not only ensure the stability of the active substance of the drug (the physical stability of the drug system of the suspension-type preparation), but also ensure that the act...
