SU66216A1 - A method of manufacturing gypsum bandages - Google Patents

Description

It is known to obtain gypsum bandages by copying the fabric and blending the non-burnt gypsum and glue substance with subsequent thermal treatment: T1 to dehydrate the gypsum.

Colloids are also known to be retardants for setting gypsum. In this way, the introduction of an adhesive substance that serves as a fixative of the giisa on the tissue, always leads to a slowdown in the sealing of the plaster dressing.

The dapse dressing time, when gypsum is fixed on gauze using starch paste, is so prolonged that their application (especially in the field, turned out to be impossible).

According to the invention, it is proposed to introduce catalysts that accelerate the process of compacting the plaster dressing. However, the addition of bisulfate leads to a weakening of the tissue. The use of medium salts of sodium sulfate and potassium destroys the tissues of the resulting gypsum bandages and the positive effect of sodium sulfate, as a catalyst, is that the dosage of it, irim enem in the production of gypsum bandages, does not have any irritating or pathogenic effect on the skin. the patient.

The fabrication of the GI-Hose bandage is as follows.

Example 1. Gauze fabric is impregnated with pulp, 1 consisting of an unbaked crushed tank of CaSO4 2Н2О mixed with 2.0-2.5% starch paste or with any other adhesive substance containing 0.5-0.8% 1 NaaSO. , or KHS04, or soluble glass, or other salts that serve as catalysts for accelerating the hIPs setting. The impregnated fabric is burned at a temperature of 170 - 200 °, after which the cloth of gauze is cut across the width and length of the bandages of the desired size.

Example 2. Gauze fabric is soaked with 2–3% starch paste containing 0.5–0.8% of catalyst, squeezed out of excessive moisture, evenly dusted with unburned finely ground gypsum, rolled for best fixation of gypsum on the fabric, roasted at a temperature of 170 -200 °, after which the cloth of gauze is cut according to the width and length of the bandages of the desired size.

The use of the raw CaS04 2H2O gypsum has a great value for production; the production has been greatly enhanced, since the commonly used calcined CaSO4-0.5 H2O gypsum is quickly grasped, which means that the process is interfered with. In addition, 131CONOMYFUEL fuel going 1a secondary dihydrate | atsi) gypsum.

In the method, the gypsum is dehydrated oiiy times, being already applied on the gauze.

Surgeons require that the plastering of PLA BAND lasts no more than 5-b minutes. The starch paste, which serves as a fixer for gypsum on gauze, acts as a retarder on the setting of calcined guis, delaying the time it takes for the gypsum dressing to harden.

The introduction of a catalyst in the process and accelerates the setting of the calcined gypsum, and the ginsawa pulp is consolidated in 3-5 minutes.

Gypsum is tightly fixed on gauze and very iMa..iiio is lost to the lee. ,:

Claims (2)

1. A method of making gypsum bandages by impregnating the fabric with an aqueous mixture of unbaked guis "gluewood, eat it, followed by heat treatment to dehydrate the gypsum, characterized in that the pulp or paste consisting of an adhesive substance in her divine gypsum, gypsum setting accelerators are introduced, for example, soluble sulfites. 2. A variation of the method according to claim 1, characterized in that the fabric is pre-wetted with a solution of an adhesive substance containing accelerators of the setting of gypsum, then it is sprayed with an unnecessary HIPSO1M and subjected to the above heat treatment.
