摘要:
A method for obtaining a traumatologic plastering with damp-proof and hard-wearing properties consisting of adding to a volume of one liter of containing product 96 through 99% of warm water having a value of 7.65 pH, the following components being added to obtain 1 liter of this product: 43 mg of Sodium, 7.30 mg of Potassium, 8.02 mg of Calcium, 1.20 mg of Magnesium, 0.40 mg of Americium, 580 mg of Nitrate, 0.53 mg of Nitrite, 25.6 mg of Sulfate,
摘要:
The instant invention relates to a novel water resistant orthopedic bandage which includes a hardenable plaster of Paris composition, including a reactive silicone polymer supported on a flexible carrier. The amount of plaster of Paris may range from 100 to 600 grams per square yard of carrier, preferably from 396 to 425. The amount of reactive silicone may range from 0.5 to 20 parts per hundred parts plaster of Paris, preferably from 0.5 to 10, e.g. about 4 parts silicone per 100 parts plaster of Paris. The novel orthopedic bandages of the instant invention show improved water resistance throughout the curing cycle of the bandage. Also, when compared to the prior art plaster of Paris bandages the instant bandages have improved "green strength".
