Embodiment Construction

[0018] Please refer to the accompanying drawings to illustrate its implementation process:

[0019] The processing technology of hydrocolloid dressing, the steps are as follows:

[0020] Ingredients: Mix medical hot melt adhesive and sodium carboxymethyl cellulose, that is, mix the hydrocolloid raw materials in proportion; other auxiliary materials can be added.

[0021] Extrusion: Input the prepared material into the extruder and extrude it by heating to form a block or strip extrudate. The extruder is generally a common extruder on the market, either single-screw or twin-screw. Can.

[0022] Lamination: The extruded material, film and substrate are compounded by a laminating machine, which is the product of the present invention figure 1 The press machine indicated in.

[0023] The structure of the pressing machine is as figure 1 Shown, two pressing rollers 3,4, wherein one pressing roller 3 is provided with the groove of hydrocolloid shape, just the shape of hydrocolloi...

Abstract

The invention discloses a processing technology for hydrocolloid dressing, comprising the following steps: burdening: mixing medical hot melt glue and sodium carboxymethylcellulose; material extrusion: inputting a burdened material into an extruder, extruding through raising the temperature to obtain blocky or strip extrusion materials; and laminating: compounding the extrusion material, a membrane and a substrate through a laminating machine. The invention has the beneficial effect of plane and smooth compounded hydrocolloid dressing without wrinkle.

Description

technical field [0001] The invention relates to a processing technology of a hydrocolloid dressing. Background technique [0002] Hydrocolloid is used as a medical product for protecting wounds and absorbing wound exudation. In the prior art, when the film is combined with hydrocolloid, it is uneven, easy to wrinkle, and difficult to form. Contents of the invention [0003] Aiming at the deficiencies of the existing technology, the invention provides a processing technology of a hydrocolloid dressing. [0004] In order to achieve the above object, the technical scheme that the present invention takes is: [0005] The processing technology of hydrocolloid dressing, the steps are as follows: [0006] Ingredients: mix medical hot melt adhesive and sodium carboxymethyl cellulose; [0007] Extrusion: Input the prepared material into the extruder, extrude it by heating, and turn it into a block or strip extruded material; [0008] Lamination: Composite extrudate, film and su...
