Why is food grade silicone tubing produced in a dust-free workshop?

Dust-free workshop does not mean that there is no dust, but that the dust must be controlled within a certain amount. For the production of food-grade silicone tubes, the dust particles on the surface of the product cannot be seen with the naked eye. It is safer and more stable than other products during use. As we all know, the surface of silica gel after extrusion is bright and sticky, especially the strong adsorption capacity, it is easy to absorb dust in the air and stick to the surface, making people feel a little dirty, even if it is wiped with alcohol, it will solve the symptoms, not the root cause, so if you want to solve it fundamentally, you can only Starting from the production environment of food-grade silicone tubes, the whole workshop is a dust-free workshop, so why is there dust?

  Food-grade silicone tube is a product that can be directly contacted by the human body. It requires great safety features and requires that the product must not produce harmful gases or substances (including dust) that are harmful to the environment or human body from source to production. The environment in which the silicone tube is made is not clean enough. Due to the characteristics of silica gel to absorb dust (the dust carries a lot of bacteria), if it is not sterilized, it will still affect the human body. The dust is adsorbed on the surface of the food-grade silicone tube and the user directly These dusts can be directed to the human body. The food-grade silicone tube produced in the clean room will hardly stick to dust and naturally will not have any effect on the human body.
  Another advantage of the dust-free workshop for food-grade silicone tubes is that the impurities will be greatly reduced. After the company purchases the product, some impurities (called particles in the industry) will be found on the surface or wall thickness of the transparent food-grade silicone tube. These impurities The source of most of the occurrence is still in the process of extrusion and densification. Because the environment is not strict enough, the dust (≥500 micron particles) in the air falls into the rubber compound (hard to find with soft eyes) and it is produced and formed by the extruder. Food-grade silicone tubes indicate that there are particles on the surface that affect the appearance of the product. If these particles are large and obvious, such food-grade silicone tubes cannot be sold (it does not comply with food safety regulations). The dust-free workshop in the silicone industry will maintain a stable temperature (the temperature of the machine cannot be changed continuously, and the central air conditioner can reach the unstable temperature of other air conditioners). The dust-free workshop is a closed environment and the indoor temperature should be controlled at 21°~ Between 26°, a stable temperature will effectively slow down the hardening and cross-linking speed. This can only be operated in a closed environment, and the clean room can meet this requirement. The temperature stability in the clean room will affect food grade silicone. The hardness of the tube has a positive and negative tolerance range. The temperature of the clean room during the period of silica gel compaction is more stable, the better. Only the clean environment of the clean room can achieve this. The longer the raw material of the food grade silicone tube is exposed outdoors, the better. In other words, the greater the positive and negative tolerance of the hardness of the finished product, the positive and negative tolerance of the hardness of the food-grade silicone tube is generally controlled at about ±3 degrees in a clean environment with a constant temperature in the clean room, but the food-grade silicone tube produced in the clean room is not used. The positive and negative tolerance is between ±5-7°, which proves that the hardness stability of the food-grade silicone tube produced in the clean room is greater than that of the food-grade silicone tube in the ordinary environment.
  Generally speaking, the dust-free workshop is an indispensable symbol of the company's external strength for silicone products companies. At the same time, it has safety and stability for food-grade silicone tubes, medical silicone tubes, pharmaceutical silicone tubes, and peristaltic pump silicone tubes. There is a lifting effect.
