467. What are the major categories of binding materials for binding? A: There are many kinds of binding materials used in binding, and the sources are extremely broad. There are roughly the following major categories, namely, animal, starch-based, casein, natural resins, celluloses, and artificial synthetic resins. 468. What is animal adhesive material, including several? A: An animal's skin, intramuscular tissue and bones, after chopping → lime soaking → washing → acid neutralization → washing → heating → filtration → concentration → cooling setting → cutting → drying → inspection → crushing and other packaging Made of adhesive material. Animal adhesive materials include bone glue, gelatin and fish glue. 469. What is bone glue? What are the characteristics? A: Gelatin is a gelatin gelatin protein with low purity; its adhesive film is very firm and flexible after it is formed, but it is not water-resistant. When it meets water, it will expand the adhesive layer and lose its adhesive strength. Its corrosion resistance is also poor. It also changes when the temperature is high and the humidity is high. The characteristics of bone glue are: less water, fast drying, good shaping, high bonding strength, good performance, and low price and easy to use. It is the most used one in animal adhesive materials. 470. How should bone glue be used? A: When using the first volume equal or slightly more water (preferably with hot water) will soak the plastic block for about 8 hours to make it soft, and then use a hot bath to 65 ~ 85 °C, until the liquidity of the colloid Uniform, viscosity can be used after appropriate. The ratio of glue to water depends on the required viscosity, generally 1:3. Bone glue has a small amount of precipitation in use, so use it while adding water, and stir it at the same time; pay more attention to prohibiting the use of cold water in use and destroying the fluidity of the colloid. 471. What is gelatin? how to use? A: The gelatin component is similar to bone glue, but its purity is high and its colloid is transparent. It is a high purity protein. The raw materials for making gelatin are high-quality fresh animal hides, bones and scraps. Gelatin can be added with the corresponding moisture before use. When it is about 50°C, it can be completely melted into the required glue. The usual temperature is 40-70°C. Less than 30°C can still be used. The method of use is the same as that of bone glue, which is a kind of animal adhesive material with a higher grade than bone glue. However, because of its high price, it is generally used in a small amount, and is only used when pasting some high-grade books, pictures, and other book covers. 472. What is fish glue? A: Fish gelatin is the best adhesive material in animal glue, and it is the highest price in animal glue. It is made from scraps such as fish skin. The method of making and using it is the same as that of other animal glues. However, due to the fact that in recent years, the fish has acquired many substances, high benefits, and a wide range of uses, it is hardly used for the production of adhesive materials.
