Detailed explanation of silica gel bonding process, what glue should be selected for secondary bonding molding?
It also involves bonding. For some products that have been in contact with human skin for a long time, consumers will have a lot of doubts. Glue is always a chemical material. Whether it is smell or material, it will cause certain harm to human body. Will the silica gel products bonded with it really not cause harm to people?
For people who know about glue, it may not be necessary to interpret too many popular science. In the cognition of most consumers, the glue closest to us is fast drying glue or slow drying glue. They don't know much about the materials of glue, so they have always misled that glue will produce biochemical reactions and cause harm, so it also leads to
Silica gel is a porous material with different particle sizes formed by proper dehydration of silicic acid gel. It has an open porous structure and can adsorb many substances. It is a good desiccant, adsorbent and catalyst carrier.
Silicone products can meet different needs in different fields. Everyone may know what silicone is and what material is made of silicone. But what is the main function of silicone? In our lives, silicone rubber is mainly used In what ways? At present, what kind of products are there in silicone products
Silicone tubes require different hardness due to their different use requirements. For example, the hardness of food grade silicone hose is different from that of medical silicone hose. Some customers asked: for the same silicone hose formula, the hardness of the rubber produced by the open mixer is about 10 ° lower than that produced by the internal mixer. Is this caused by the way of rubber mixing?
When producing silica gel products, some products require secondary vulcanization, which is also called post vulcanization. Why do you do this? What's the point?
Green development is at the forefront of energy conservation. In a long-term strategic sense, green development is profitable and harmless for the future development of the food grade hose industry. The food grade silicone hose industry is highly dependent on resources, and learning how to save resources is a key jumping point in the transformation of enterprises.
Straws are often used in daily life. The traditional plastic straws have been listed in the plastic ban order in order to reduce plastic pollution. At present, the degradable straws of paper straws have become the stage products of.
