The invention relates to a device for evaluating the foaming property of an air-soluble surface active agent. The device comprises an air source part, an evaluating kettle, a liquid part and an intermediate container part. The evaluating kettle in the device is internally provided with a first piston, so that the pressure of the evaluating kettle can be maintained or raised by the means that the distilled water is pumped into the evaluating kettle by a first constant-flux pump in the process of test; the pressure of the evaluating kettle can be reduced by the means that the distilled water is discharged out by the means that a first set of valves are turned on, so that the control for the pressure of the evaluating kettle can be realized, and the cloud point pressure and the cloud point temperature of the air-soluble surface active agent in supercritical carbon dioxide can be conveniently measured. Through the rotating of the evaluating kettle, the air-soluble surface active agent and the supercritical carbon dioxide can be sufficiently and evenly mixed with each other when the solubility of the air-soluble surface active agent in the supercritical carbon dioxide is measured, so that the phase equilibrium status can be achieved; and the foam regenerating property of the air-soluble surface active agent can be evaluated since the air-soluble surface active agent can float under the action of the gravitational differentiation of the evaluating kettle when the regenerating property of the air-soluble surface active agent is measured after the foam of the air-soluble surface active agent bursts.

The invention relates to a method for preparing a fiber-containing silicon dioxide aerogel composite thermal insulation material. The method is mainly characterized by comprising the following steps of: adding fiber and an infrared sunscreen agent into aerogel precursor solution to form composite gel, and treating the composite gel to obtain fiber-containing silicon dioxide aerogel composite powder; and adding a little binding agent and performing compression molding by adopting a half-dry pressing method, and performing heat treatment to obtain composite products in various shapes. By adopting a technical route for preparing the composite powder and molding by adopting the half-dry pressing method, products in complex shapes are easy to produce, supercritical drying at high cost and in danger of high pressure is avoided, and the method is easy for mass production. By taking industrial silica sol and industrial spirit as main raw materials for preparing silicon dioxide aerogel, addinga drying controlled chemical additive, the infrared sunscreen agent and the fiber in turn and finally slowly adding the industrial spirit until gelling, the fiber and the infrared sunscreen agent canbe fully and uniformly mixed with the aerogel in the composite powder, the thermal insulation of the materials is improved, and a higher-strength light thermal insulation material is prepared.

The invention discloses panax notoginseng active ingredient-containing medicinal toothpaste and a preparation method and application thereof. The panax notoginseng active ingredient-containing medicinal toothpaste comprises 0.1 to 0.4 weight percent of total panax notoginseng saponins and 0.2 to 0.5 weight percent of panax notoginseng polysaccharide which are panax notoginseng active ingredients, abrasive, a wetting agent, surfactant, a foaming agent, adhesive, a stabilizing agent and deionized water. The preparation method for the toothpaste comprises the following steps of: preparing materials, mixing, grinding, and degassing to obtain a toothpaste body. According to the toothpaste, total panax notoginseng saponins and panax notoginseng polysaccharide are used as the core functional components of the toothpaste, so that the toothpaste has the function of cleaning teeth, and the obvious effects of promoting recovery of dental ulcer, gingivitis and periodontitis, inhibiting swelling and aching of gums, relieving bleeding of gums, and delaying gingival atrophy and aging. The total panax notoginseng saponins and the panax notoginseng polysaccharide which are used as the active ingredients are natural plant extract, so that damage to ecological environment of normal flora in an oral cavity can be avoided, and the panax notoginseng active ingredient-containing medicinal toothpaste is suitable to be used for a long tome and is good in effect.
