How to use gypsum matrix

What is gypsum matrix? Plaster is divided into two parts, one is ointment and the other is medicine. It is prepared by mixing ointment and medicine and spreading on plaster cloth.

Plaster, also known as plaster matrix, is the carrier of traditional Chinese medicine in plaster, and also has sticky properties, so that plaster can be attached to patients' skin.

Surface.

The components of plaster matrix are varied, and different plasters have different components of plaster matrix. Specifically, the plaster matrix is mainly divided into three types, one is transmission type.

The production of unified gypsum matrix has a long history, mostly by hand, and the preparation of production depends entirely on experience and family tradition. The second is solvent-based plaster matrix, and the third is non-boiling.

Second, the development process of gypsum matrix

Several common gypsum substrates are introduced below.

1: black plaster matrix, sesame oil and tung oil are boiled with lead, and produced by hand workshops, with a long history, complicated technology and no uniform specifications.

Based on personal feelings, the curative effect is recognized, but it contains heavy metals such as lead and Dan, which has negative effects.

2. Wax paste matrix, which contains no lead and Dan, has no side effects, but has poor viscosity.

3. Rosin paste matrix, composed of rosin and camphor, is well formed, but its viscosity is poor, and there are many grades of rosin, which is produced seasonally.

4. White plaster matrix, mainly oil and palace powder, is expensive and not commonly used.

There are many kinds of traditional plaster substrates, all of which have been widely used in history, and their curative effects have been confirmed for a long time in history, but they are all the same.

It is characterized by small quantity and no standardization, which can not meet the needs of socialized large-scale production and is withdrawing from the main field of gypsum production.

Flow.

The following are several main gypsum substrates used in modern gypsum mass production.

1: Boiling-free gypsum matrix is convenient to produce and does not contain lead, but it is easy to cause pollution, inconvenient to transport and store, and high in production cost.

2. The matrix of cataplasm is made of hot melt adhesive and solvent by mixing and heating, which has the advantages of good viscosity but poor drug permeability.

3. The matrix of solvent-based hot-melt pressure-sensitive adhesive plaster has good durability, but the production process of plaster is complicated, the cost is high and the pollution is great.

4. Under the traditional technology, solid plaster matrix has the advantages of convenient production and use, good durability and good viscosity, and is the mainstream matrix in plaster production market. Disadvantages are as follows

Many manufacturers, poor technology.

5. Under the new technology, the solid matrix of hot-melt pressure-sensitive adhesive tape is solid, and the color can be customized according to the customer's needs, which is convenient for production and use.

Large dosage, easy permeability, good durability and good viscosity. The disadvantage is that the paste matrix has high technology content and the production technology has not been widely promoted.

Each gypsum matrix has its own advantages and disadvantages. However, with the development of society and technology and the appearance of new technology, new gypsum matrix is always eliminated.

Old gypsum matrix, of course, has its own way of existence for the time being because of the difference of time and environment.

Third, the application field of gypsum matrix:

Gypsum matrix is mainly used for gypsum processing. Plaster processing is divided into family workshop, hospital outpatient service and factory assembly line scale production.

There are three forms, each of which uses different gypsum substrates, and different gypsum substrates adapt to different production and processing methods, but the mainstream is still the most important.
