Causes of sticking of braided silicone hose

时间:2022-06-27浏览次数:653

Woven silicone tubes stick together because of the characteristics of silica gel itself. After the silica gel is cured, the molecules will be released outward, which is easy to absorb dust. For items that are also silicone, they will also stick together. However, as silica gel itself is an inert material, its adhesion is not strong and it is easy to separate. The performance and use after separation will not be affected, so when you open the package and find that the tubes are stuck together, please do not doubt the performance of the silicone tubes, and you can use them with confidence.

The method to solve the mutual adhesion of woven silicone tubes is very simple. As long as the surface of silicone tubes is coated with a layer of talc powder, or the surface is matte, they will not stick together. However, these methods are generally not accepted unless they are required for use. Because coating a layer of fog will affect the appearance of the pipe, because the silicone pipes can be slightly separated after being stuck together, which will not affect the service performance and quality of the silicone pipes, so it is acceptable for the surface of the silicone pipes to be stuck together.

How to reduce the damage and prolong the service life of silicone tube after long-term use.

1. External factors

Generally speaking, the reason why the life of silicone tube is shortened is affected by various external factors, such as over processing, light and heat, oxidation, radiation, mechanical fatigue and so on. Among these external reasons, ozone activity has a great impact.

It is reported that the amount of ozone in the atmosphere is increasing, and its chemical activity is also increasing. The final result is that the silica gel molecules in the silica gel tube are oxidized and the molecular chain is broken, thus changing the performance of silica gel and shortening its life.

In addition, food grade silicone tubes are exposed to humidity and light for a long time, and it is easy to accelerate their aging speed without appropriate protective measures.

2. Installation problems

If workers do not adopt the correct installation methods when installing silicone hose fittings and hose assemblies, the service life of food grade silicone hoses will also be shortened. When installing a hose with a small bending rate, improper use of the connector or random distortion of the hose itself are incorrect installations that shorten the service life.

These are the reasons why braided silicone hoses will stick together and affect the service life of the hoses. Therefore, it should be reasonably avoided in the process of use to prolong the service life.
