We know that many industries are using silicone strips, because it has a good airtight effect, not only in the field of medical machinery in daily life, but there are many products in the market. How to identify whether it is really a silicone strip?

Non-silicone components will cause a certain level of damage to the storage, manufacturing and physical industrial equipment performance of rubber materials. If there is a change in the content of such non-silicone window seals in the rubber material, it is likely to cause instability in the production process and material properties. For example: there are various types of natural cinnamon trees, and the properties of the natural latex collected by each type of silica gel tree are determined by the geographical environment, climate and geographical environment of the growth and development of cinnamon trees, the richness of the soil layer, the crown diameter of the rubber, and the season. It is self-evident that the content of natural silica raw rubber produced and processed by it, its disperse gel content, aging resistance, and the content of non-silica gel components such as sediment, protein and ash content Therefore, there are differences in the properties of natural silicone produced by different manufacturers. Even if it is the same manufacturer, there are differences in the properties of natural silicone produced in different seasons. Its plasticity, circulation characteristics, physical industrial equipment performance And the output effect of the silicone products produced by it will also cause vibration, resulting in unstable production process and material quality.

Therefore, it is stipulated to detect the plastic deformation maintenance rate (fire resistance grade), nitrogen content, volatile content, ash content, sediment content, color index and other components of natural rafter glue for window sealing strips, and classify natural silica gel. It is stipulated to supervise the content and dispersion of natural silica gel to meet the requirements of manufacturing and material efficacy. In addition to the rafter hydrocarbons, the combined silica gel also contains residues of liming agents, content conditioners, structural pharmaceutical preparations, unrepresented residues alone, and represented by-products. Copolymerized silica gel also has structural difficulties such as the separate occupancy of the prepolymer in the molecular formula chain, and cis-trans isomerism. Therefore, the finished rubber materials should also follow the relative standards to supervise the reliability of the raw rubber properties. Supervising the stability of the raw rubber properties is one of the important factors to ensure the stable properties of the materials. Therefore, before the raw rubber is used, it is necessary to carry out an essential test.
