Bone Granules

Bone glue is one of the most widely used animal bonding materials. Because of its appearance, it is also called beaded bone glue. The utility model has the advantages of good bonding performance, high strength, less water, quick drying, good shape setting, low cost and convenient use, and is particularly suitable for bonding and pasting hardcover book covers, and can obtain good effects.

The main component of animal glue is gelatin peptide protein. It is a kind of bone glue with low purity. Bone glue is a brittle lumps solidified body. Collagen is a water-insoluble protein. After being heated and treated, it becomes another form of protein called capsule, which is soluble in hot water and has a bonding property.

The rubber film of the bone glue is very strong and elastic, but the bone glue is not resistant to water. When the water is in contact, the rubber layer will expand and lose the bonding strength, and the corrosion resistance is also poor. If the temperature is too high and the humidity is too large, the change will be caused.
