surgical drain tube is a kind of polymer material, environmental protection, non-toxic and widely used, in recent years by the majority of product manufacturers favor, of course, there will be some problems, for example, recently a friend asked the surgical drain tube toughness is poor what is the reason? The following Xiaobian is combined with previous experience, for everyone a simple analysis:

1. Problem of material mixing system

surgical drain tube is a blend compound. The molecular weight of rubber substrate, stone powder filling amount will affect its toughness, in short, polymer rubber substrate, surgical drain tube toughness is good; Less stone powder filling material, good toughness.

2. The influence of molding temperature

Plasticization degree is an important factor affecting the toughness of surgical drain tube. If the molding temperature is not sufficient, the surgical drain tube will not be sufficiently plasticized and its toughness will be greatly compromised. As for the forming temperature of the surgical drain tube, it is necessary to consult the supplier for the recommended parameters of different mixes, brands and manufacturers.

3. Aging and photooxidation of surgical drain tube

If the surgical drain tube is exposed to ozone, ultraviolet radiation and other media, the physical properties will decrease sharply. When selecting materials, it is recommended to confirm the performance requirements of the materials between the upstream and downstream of the industrial chain, and then select the appropriate surgical drain tube, such as aging resistance, UV resistance and other properties.

4. Adding ratio of water inlet material

The surgical drain tube is a thermoplastic material that can be recycled over and over again. But the physical properties of water mouth material will decrease with the more times the material is used. It is generally recommended that when forming, the proportion of water material added should not exceed 25%. If too much water is added, the surgical drain tube toughness will be greatly reduced.

5.surgical drain tube products from structural defects

Whether the product has weld marks, and stress concentration, such as without R Angle corner, water mouth just in the stress position, etc. With these factors, the toughness of the material will decrease and it is easy to break.
