Types of plaster bandages are divided into two categories, ordinary and fiberglass, and we will examine each of them in terms of material and performance.
Ordinary plaster band
The simplest type of plaster bandages are the usual type, which have been used less in recent years. The material of these plasters is gauze dressing. The casting specialist first moistens the bandage and wraps it in layers around the injured area of the patient's hand or foot. There is also a cotton made of calcined plaster under it, which creates calcium sulfate when it comes into contact with water, and finally the plaster dries after a few minutes. It usually takes about 10 minutes for ordinary plaster to dry, and also the process Its drying is exothermic.
It should be noted that if there is not enough cotton cover under the plaster, the patient may feel some burning and pain in the affected area for some time due to high heat, and this is one of the The negative points are ordinary plaster band.
Fiberglass gypsum band
Orthopedic fiberglass bandage is made of plastic that is saturated with polyurethane resin. Resin reacts with water and dries quickly. One of the unique features of fiberglass is its flexibility and the plastering expert can easily shape it. Although the process of plastering with fiberglass is similar to the normal method, the flexibility as well as the high speed of drying and hardening, It has made fiberglass superior to ordinary plaster.
Also, the process of plastering with fiberglass plaster band is heat-generating, but despite this, the patient will not feel burning or pain in the affected area. Also, after combining polyurethane resin with water, the plaster will be completely dry and hard after about 3-4 minutes.
