What is the structure of silicone tubes


What is the structure of silicone tubes Generally speaking, the consumption structure of silicone rubber pipes is to stop processing and disposal of natural silicone rubber, and then stop processing according to the required formula. Initially, the decomposition agent and other materials involved are decomposed by rubber refining machines and grinding tools, forming one pipe after another. However, ordinary factories can present pipe construction when consuming pipes. The construction of pipes refers to the use of silicone rubber with weak white carbon black during the consumption process, which hardens during storage, resulting in a decrease in the plasticity of the rubber and the loss of processing function. This scene is called "pipe construction". reason 1. The most common theory is that under the influence of temperature, the surface of the Mars silanol group undergoes chemical reactions with the raw rubber molecules, causing them to condense, leading to rubber hardening and reduced plasticity. 2. The base atoms on the surface of white carbon black react with raw rubber molecules to form hydrogen bonds and even chemical bonds. Transforming the silicon hydroxide inside the silicone rubber into a pseudo crosslinked or micro crosslinked solid shape constitutes the curing of the silicone rubber. Disposal Measures 1. Living in silicone rubber with "structured control extrusion" is the rarest disposal method in consumption. 2. Suspend the treatment of the appearance of white carbon black to prevent the occurrence of white carbon black and rubber.

Is silicic acid gel and silica gel the same material


Is silicic acid gel and silica gel the same material Is silicic acid gel and silica gel the same material? Silicic acid, chemical formula H2SiO3. It is a weak acid, and its salt has a hydrolysis effect in aqueous solution. Free silicic acid, including Orthosilicic acid (H4SiO4), metasilicic acid (H2SiO3) and disilicic acid (H2Si2O5), is very weak. The ionization Equilibrium constant of metasilicic acid K1=2 * 10-10 (room temperature), and the orthosilicic acid is firm within the range of PH=2-3. However, if the Supersaturation H4SiO4 solution is temporarily placed, there will be amorphous silica precipitation, which is milky white precipitation, and appears as colloidal particles, precipitates or gel. Some water in the gel evaporates, and a porous monotonous solid gel can be lost, that is, rare silica gel. The silicic acid gel has strong adsorbability, and can be used as a moisture absorption agent, a catalyst, or a carrier of other catalysts. Silica gel, also called silicic acid gel, is a kind of highly active adsorption material, which belongs to amorphous substance, and its chemical Molecular formula is mSiO2 · nH2O; Except for strong bases and hydrofluoric acid, it does not react with any substance, is insoluble in water and any solvent, is non-toxic and odorless, and has strong chemical properties. Compared to silica gel, silicic acid contains more hydroxyl groups and is a high-purity reagent silica gel.

The firmness of food grade silicone tubing


With the continuous development of food industry technology, the raw materials for the inner and outer packaging of many products are also being upgraded from time to time. Among them, food grade silicone tubes are also very rare in this range. Of course, in the process of understanding a new type of material, we should also pay attention to its firmness and safety. Let's have a detailed understanding above! Firstly, strong low temperature resistance Regarding the internal and external packaging materials of food, low temperature resistance is a very important characteristic, which indirectly affects the safety of this material. Assuming that the low temperature resistance is relatively weak, it is likely to release a certain amount of water that is harmless to health. Secondly, good clarity The permeability of food grade silicone hoses is relatively high. In this way, high-tech methods can be used to enhance the adhesion of the sol during the production process, thereby enhancing the permeability of the product. This can improve the visual effect for consumers. Thirdly, there is no odor Regardless of the type of information in the food, if there is an odor present during the process of discontinuing consumption and manufacturing, it is likely to affect the quality of the product. Therefore, food grade silicone tubing also has this disadvantage, as it does not have any odor. This way, during the process of discontinuing manufacturing, it will not affect the quality of the product and is not prone to decay in a sealed environment. Overall, the disadvantages of food grade silicone tubing are quite clear. In the process of data comparison, it can be considered as high-quality silicone material. Therefore, looking at this plastic material, it can meet the needs of ancestors for a healthy diet and ensure the consumption of high-quality food.
