What are the characteristics of braided silicone hose and how to deal with yellowing?
时间:2022-05-23浏览次数:1267Silicone tube, also known as silicone hose, is the circulation and coating carrier of liquid, gas and other substances. Industrial silicone rubber pipe can be divided into "extruded pipe" and "special pipe belt", which are commonly used in electronics, aviation, petroleum, food, medical and other industries. With the development of society, people's living standards are gradually improving, and they are increasingly pursuing a healthy life. In order to pursue a healthy life, food grade plastics are slowly replaced by food grade woven silicone tubes. What are the characteristics of edible silicone tubes?
It belongs to environmental friendly silica gel, which is produced by batch method with newly imported food grade silica gel raw materials. It has the characteristics of tasteless, no yellowing, good softness and elasticity, high transparency, no deformation by twisting, no frost spraying, no cracking, long service life, cold and high temperature resistance, no fading, no scaling, no peculiar smell when placed in water for a long time, etc.
Sometimes when we use woven silicone hose, we find it turns yellow.
Its yellowing may be caused by its material, temperature, high content of heavy metals, and the use of oil. So how can we prevent the silicone hose from yellowing?
Pay attention to the raw materials when purchasing, and the temperature should be controlled below 140 degrees when using. Try not to use oils, because their compatibility is poor, and it is easy to bring additives in oils to the surface.
There are two methods to produce silicone hose: molding method and extrusion method. Molding requires more labor, but the environmental performance is poor and the price is cheap. The extrusion process with good environmental performance is produced by machinery, which does not need manpower, but it is expensive.
Before buying braided silicone hose, you need to know what kind of silicone hose you want to buy, and then determine its length, system working pressure, use environment and size of silicone hose.
