Animal glue operation should pay attention to matters

Animal glues are mainly used as industrial adhesives, emulsifiers and emulsion stabilizers, flocculants in beneficiation, sizing agents in the paper and textile industry, as well as in the printing industry for making plates and manufacturing ink rollers, and other animal glues. The food, photographic materials, pharmaceuticals, and cosmetics are also used in a wide range of important applications. The operation method of animal glue is as follows:

1. Jelly glue: Pre-melting at 60-65°C, add hot water according to 2%-5% of the weight of the glue according to the need, make it reduced to glue, dilute to the same viscosity, and achieve the best mechanical processing performance.

2, granular: the powder and water according to 1:1 (that is, 1 part of plastic powder plus 1-1 cold water soaking) 40-60 minutes, until the water swelling and indirect heating and dissolution, sol can not be directly heated, sol Temperature is controlled below +/- 75°C. Animal glue will solidify into jelly when the temperature is low, such as in winter, the temperature is relatively low, the air humidity is small, the glue cooling is faster, so the temperature of the glue can be used higher, the operation is faster, and the operation speed is improved; In summer, the air temperature in the room is high and the air humidity is high, so the temperature of the glue used is lower and the operation can be slow.

The appearance indicators of animal glue products are identified through the following two general directions:

1. Appearance: Transparent amber jelly-like and light yellow, brown granular two.

2, product viscosity: 3500+500CPS before melting
