First, the application of silicone tube:

The silicone tube has the characteristics of high health grade, so it is used for the transportation of medicine and food. Such as liquid medicine, juice, milk, wine, etc., widely supporting pharmaceutical, biomedical, life science, cosmetics, and food and beverage, water treatment, laboratory, printing, biotechnology and other industries.

Two, the advantages and classification of silicone tube

The advantages of silicone tube are mainly as follows:

1, high health grade, non-toxic odor, almost no odor effect on the solution medium, can be used for life medicine, health food and other occasions.

2, high temperature range, such as platinum sulfide silicone tube up to 260℃, to meet most of the health grade medium transport temperature requirements.

3, elasticity, bending durability and other excellent, can be used for precision instruments such as sanitary pump, drip machine and other equipment, long-term use without torsion deformation, no cracking.

According to the structure and process characteristics of silicone tube can be made as follows simple classification

1. Single layer silicone tube for peristaltic pump

With excellent flexibility, elasticity, so used in sanitary pumps, peristaltic pumps, precision instruments and equipment

2, single layer braided mesh silicone tube, multi-layer braided mesh reinforced silicone tube:

The woven mesh enhances the voltage resistance of the silicone tube, which is used for conveying medicine, food, cool beverage water, etc. The softness of the hose is very convenient for air-conditioning rooms, transformers, FA machines and other high and low temperature equipment, as well as CIP/SIP cleaning.

3, steel wire reinforced silicone tube

Built-in steel wire around the silicone hose for suction operations, but also improve the silicone hose pressure resistance, easy to use in specific occasions.

4, platinum vulcanization process silicone tube

The platinum vulcanization process silicone hose has higher health grades, such as platinum vulcanization silicone hose meets USP Class VI, FDA CFR 177.2600, ISO 10993, and 3A standards. At the same time, platinum vulcanized silicone tube has better flexibility, durability, heat resistance (up to 260℃), sustainable CIP, SIP or ray sterilization or autoclave, with ordinary silicone tube incomparable advantages.

Three, the use of silicone tube suggestions and countermeasures

1, for the silicone tube parameter requirements, must not be used subjectively.

2. Bubbling inside and outside the wall of the silicone tube may occur for the following reasons:

(1) In the production process, the ratio of raw materials, raw materials are not pure, there are magazines or mixed with air, will cause silica gel tube bubble, serious will cause tube wall rupture

② Production process problems, immature industry and unqualified quality management control will cause defective silicone tube, uneven wall thickness will certainly affect the use of silicone tube.

(3) The external environment of the silicone tube, whether there is the influence of ultra-high temperature object gas, whether there is spraying sparks, special chemicals and so on

3. The silicone tube becomes yellow, yellow and sticky

(1) Normally speaking, if it is used for a long time, the external slightly yellow is normal, the internal can be cleaned at high temperature, acid and alkali cleaning to keep the internal clean and health, but if the poor silicone tube is selected, it may be used several times will appear discoloration soft and other problems, it is recommended to replace the good quality silicone tube in line with the requirements of the working condition in time.

② If the silicone tube is sticky outside, you can check whether the external environment has the influence of special substances, and whether the internal conveying material is within the conveying range. If not, it may be the quality problem of the silicone tube, and it is recommended to replace it.

4. Storage of silicone tube

① Should be sealed storage, prevent rain, sunlight exposure, to cool environment is more appropriate.

② Should avoid contact with condensed silicone rubber vulcanizing agent, as well as amine, sulfur, phosphorus compounds and some metal salt chemical agents.

(3) If the silicone tube is equipped with chuck, flange and other joints, the chuck joint should be wrapped with packaging materials such as pearl and cotton to prevent damage.

Iv. Finished product production of silicone tube assembly

Silicone tube is often used with sanitary joints, easy to install and remove cleaning, commonly used joints are quick chuck type, SMS/DIN movable nut quick connection, flange joints, etc.
