Shanghai Gel King Insulation Products Co.,Ltd, as a professional gel pack manufacturer, produces and supplies various life gel products for customers all over the world. Let's talk about the properties of the gel below.
Elastic gel: A type of gel is much smaller in volume after drying, but still retains its elasticity.
Brittle gel: Another type of gel does not shrink much after drying, but loses its elasticity and is brittle.
Elastic gel maintains elasticity. Most of the fragile gels are inorganic gels for muscles, skins, blood vessel walls, and cellulose that make up plant cell walls. Its mesh structure is firm and not easy to stretch. Silica gel, aluminum hydroxide, etc., are widely used as adsorbents.
2. Swelling (swelling)
When the dry elastic gel is put into an appropriate solvent, it will automatically absorb the liquid and swell. This process is called swelling or swelling. Brittle gels do not have this property. In the physiological process, swelling plays a very important role. The younger the organism, the stronger the swelling capacity. As the organism ages, the swelling capacity also decreases.
3. De-sizing (de-liquid shrinkage)
After the newly prepared gel is placed for a period of time, a part of the liquid can be automatically and slowly separated from the gel, and the volume of the gel itself shrinks and becomes two-phase. This phenomenon is called separation of the slurry or shrinkage of the glue. For example, the blood is placed to separate the serum, the secretion of glands, and the starch paste is placed to separate the liquid, all of which are the phenomenon of gel separation.
The essence of separating pulp is the continuation of the gelation process. Gel products have a wide range of applications in medicine. For example, dry silica gel is a desiccant used in the laboratory. In production and scientific research, electrophoresis and chromatography often use gel as a support medium.
4. Multiphase, high dispersion and instability are the basic characteristics of sol. Sol has Tyndall effect and can be distinguished from solution.
