Abstract (Croatian)
Gipsani zavoji često se koriste za imobilizaciju ortopedskih ozljeda. Prilikom njihovog namakanja u vodi dolazi do egzotermne reakcije, a oslobođena toplina može dovesti do nastanka opekotina na koži. Nakon omatanja zavoja i namakanja vodom nastaje slojeviti kompozit kojemu je matrica medicinski gips, a ojačalo pamučna mrežasta gaza. U ovom radu ispitan je utjecaj temperature sadrenja i debljine na mehanička svojstva gipsanih zavoja od triju različitih proizvođača. Zavoji od 10 i 15 slojeva su načinjeni pri različitim temperaturama sadrenja. Trotočkastim ispitivanjem određena su mehanička svojstva pri savojnom opterećenju. Praćena je promjena temperature sadrenja tijekom očvršćivanja gipsanog zavoja.
Abstract
Orthopedic plaster casts are often used for immobilization of orthopaedic injuries. While they are soaked in water, an exothermic reaction occurs and released heat can cause skin burns. After wrapping and soaking the plaster, a new layered composite is made whose matrix is medical plaster and its reinforcement is mesh gauze made of cotton. In this study effect of temperature of casting and thickness of layers on mechanical properties of orthopedic plaster casts from three different manufacturers have been made. Plasters are made of 10 and 15 layers at different temperatures of casting. Mechanical properties are determined under flexural load by means of the three point bending test. The temperature change of casting is measured during the curing of orthopedic plaster casts.
