Natural Extracted Industrial Bone Glue Beads Pearls for Manufacturing

Product Description

Product introduction
bone glue is one of the most widely used animal bonding material.Because of its appearance is also known as the pearl beads shaped bone glue.Its characteristic is: good bondability, high strength, less water, quick drying, good bond to finalize the design, and low cost, easy to use, especially suitable for the stick and paste the hardcover book sealed shell, can get good effect.
Bone glue performance
The main components of the animal glue is a peptide protein gel.A kind of bone glue of low purity.Bone glue is rigid block solidified body.Collagen does not dissolve in water, after heat treatment, another, formation of a protein called the performance of the protein, soluble in hot water. Bone glue film formed strong, elastic, but bone glue is not waterproof, water will lose rubber expansion and compression strength, its corrosion resistance is poorer, has also changed the temperature too high, the humidity too metropolitan cause change.
Bone glue USES
(1) as a binder for pencil, emery cloth and sand paper adhesive and glued wood, binding books, etc.
(2) is used for printing plate and metal plate and badges.Adding dichromate bone glue solution, after drying, coating on the metal surface to form a thin layer of insoluble after exposure, exposure was hidden and not subjected to the part still soluble in water and wash, so you can take advantage of the etched into print, etc.Also can be used for silk screen printing.
(3) used as electroplating additive.Add a small amount of bone glue in plating solution can make the coating on the surface of the light.
(4) as a sizing agent for paper and textile industry.Straw hat was the bone glue, then treated with formaldehyde, not easy to deformation and can be waterproof.
(5) as a coagulant aid.Bone glue is a kind of animal glue, is a chain of natural polymer material, main ingredients are protein, its molecular weight between 3000 ~ 80000, soluble in water, additive in water by adsorption after major Bridges promote stable colloidal particles aggregation.
Bone glue method of use
Use of bone glue with equal or slightly more volume of water (best) hot water soaking bone glue for 10 hours, make soft rubber block, and then heated to about 75 ºC, making it a glue solution can be used.Glue and water ratio should be according to the required viscosity, water viscosity more low and thin: less water viscosity is high and thick.Hot glue adhesive when temperature is unfavorable and exorbitant, temperature over 100 ºC may be due to molecular degradation decreased viscosity, gel aging metamorphism.Traces of precipitation in bone glue is in use, so to use while adding water to stir, to adjust the viscosity and liquidity.Hot glue must be used when the heat bath method, direct heating should not be stored glue container.
Bone glue to keep in a certain temperature conditions can only be used, as a result, when used to add water, add water and colloid temperature should be basically the same, do not add cold water.Because bone glue to keep a certain temperature (75 ºC to + 10 ºC), add cold water temperature drop of glue can appear after coagulation TiaoKuaiZhuang, which might affect the bonding effect.Use of bone glue coating, even faster, and not a dip in gum rubber causes too much uneven coupling adhesive glue leakage, seepage problems.
