一,Silicon hoses commonly have bubble and fracture flaws
Defect inside the bubble
Commonly seen as microscopic holes within the pipe wall, bubbles are an issue with many silicone hoses. Sometimes these bubbles aren't visible to the human eye, but when they're stretched or made transparent, they stand out much more.
2. Pinholes and bubbles on the surface
On the outside or inside of the hose, surface bubbles typically manifest as tiny protrusions, depressions resembling pinholes, or partially see-through regions. These kinds of flaws are unacceptable since they detract from the product's aesthetic value and can make cleaning and disinfecting more difficult
3. Cracks, both visible and unseen
When you leave the plant, cracks may not be immediately noticeable. While some silicone hoses may seem OK at first, tiny fractures may start to show up on the surface after prolonged bending, use at high temperatures, or exposure to cold and hot temperatures back-and-forth.
二,Examining the primary reasons why silicone hoses develop bubbles and splits
1. Varieties in the grade and quality of raw materials
Grades of silicone raw materials vary greatly in terms of purity and the durability of their molecular structures. Problems like bubbles and age cracks are common when using industrial grade silicone in situations with a high demand.
2. Mixing and exhaust procedures don't have enough control.
Air retained inside the rubber substance during mixing causes permanent bubbles to form during extrusion and vulcanisation if the silicone is not completely vented. There are a lot of bubble faults that can be caused by this.
3. The vulcanisation process is unstable.
When it comes to the physical qualities of silicone hoses, sulphurization is an essential stage. The likelihood of fracture formation can be increased due to either loose material structure caused by insufficient vulcanisation or brittle silicone caused by excessive vulcanisation.
4. Problems with production environment and equipment correctness
A number of factors can influence the structural integrity and surface quality of silicone hoses, which in turn increases the likelihood of defects. These factors include mould wear, insufficient precision of the extrusion equipment, and dust contaminants in the production environment.
三,How gaps and air pockets affect the functionality of silicone hoses
1. Effect on the efficiency of sealing
Sealing and transporting are two of silicone hoses' primary uses. The integrity of the pipe wall can be compromised once bubbles or cracks appear, which can cause micro leaks, unstable pressure, and eventual system collapse.
2. Effects on resistance to voltage and temperature
Conditions of high heat or pressure increase the likelihood of deformation in defective regions. The lifespan of hoses is drastically diminished due to the expansion of bubbles at high temperatures and the propagation of cracks during cold and hot cycles.
3. Effects on public health and food safety
In the medical, pharmaceutical, and food industries, bubbles and cracks can potentially be a hygiene problem. In addition to making cleaning and disinfection more difficult, tiny gaps can harbour residual media and bacteria, which can lead to non-compliance with applicable standards and certification criteria.
四, What are the ways to identify silicone hoses that have bubbles or cracks?
1. Examination by sight and transparency
Particularly useful for see-through silicone hoses, bright illumination or backlighting can reveal internal bubbles, contaminants, or uneven structures.
2. Rebound and bending tests
One crucial way to make sure a material is stable is to bend it in the same way over and over again and see if it breaks, whitens, or has significantly worse rebound performance.
3. Testing for pressure resistance and leaks
The dependability of hoses in real-world operating situations can be evaluated through continuous testing at rated working pressure, which can quickly pinpoint regions of possible defects.
五,'How can problems with purchase and use be prevented?
1. Define exacting criteria for applications and quality benchmarks
Products of matching grades and standards should be chosen depending on the usage scenario, not universal selection, because the requirements for silicone hoses vary greatly among applications.
2. Pick vendors whose procedures are well-established and whose quality is uniform.
The dependability and uniformity of silicone hoses can be better guaranteed by suppliers who have comprehensive production processes and quality inspection systems.
3. Considering factors other than cost when making a decision
Compromises in raw materials or processes are generally associated with low pricing, which can lead to higher hidden costs in applications with strong demand.
