highly active adsorbent material, which belongs to amorphous material. Silica gel is a kind of amorphous silicon dioxide, mainly composed of silica. Its chemical property is stable, and it does not burn. Chemical formula is xSiO2?yH2O. Silica gel contains organic silica gel and inorganic silica gel. Inorganic silica gel is a highly active adsorption material. It is usually prepared by reaction of sodium silicate and sulfuric acid, and a series of post-processing processes such as aging and acid bubble. Household use desiccant, humidity regulator, deodorizer belongs to inorganic silica gel.Organic silica gel is an organosilicon compound. It refers to a compound containing Si-C bond and at least one organic group, which is directly linked to silicon atoms. It is maicustom wristbandsnly divided into four categories: silicone rubber, silicone resin, silicone oil and silane coupling agent. There are 4 types of silicone products, moulded silicone products, extruded silica gel products, liquid silica gel products and special silicone products. Silicone rubber is one of organic silica gel and it is one of the moulded silicone products Temperature resistance, weatherability, electrical insulation performance, Physiologicustom wristbandscal inertia, Low surface tension and low surface energy are the outstanding characteristics of organic silica gel. The one we use to make bracelet is named polysiloxanes di-Me Me vinyl vinyl group-terminated chemically. We add curing agent to the soft original silicone rubber and mix them evenly, then put it to molding machine with high temperature of about 200℃, a few seconds later the silicone rubber gets solidified. Here comes the silicone bracelet with custom logo by mould. Characteristic of the silicone rubber stay same on the process but it get more strengthened. There are 8 steps to make a rubber bracelet. Design the artwork. An artwork includes the information of order number, size, logo style, order quantity and other options like glowing and individual pack. Make the mould or film. A mould is needed for debossed, embossed, colorfilled styles. We make a mould and set it in the machine, the high temperature of about 200℃ will solidify rubber into the sharp of bracelet. A film is functioned like a mould but it is for printed wristband only. It transfer the ink to the surface of bracelet as logo and wording. Prepare the rubber material. A rubber bracelet is mainly made from silicone rubber, and some other accessories like curing agent which solidify the soft rubber, and Color masterbatch which makes bracelet colored. We will mix these material evenly in a blender. It comes out a ball of rubber. We need to measure it into blocks of almost same weight which as much as the weight of a wristband. Produce bracelets by the mould. As we mentioned before in 2nd and 3rd step, we will transfer the blocks to bracelets by a set of moulding machine of high temperature. When it cool down, it gets the characteristic of a bracelet, smooth and strengthened. Edge cutting. A semi-product of rubber bracelet has rough edges, we have to cut it off. The rough edge is cut by machine. It will be good. Color the logo and wording. The bracelet comes out from moulding machine without colors on the logo and lettering. We have to fill the ink or print the ink on the bracelet. Different style has different way of printing. Clean the product. As the bracelet has static electricity, dust will be on the surface and hard to move off. So we need to clean the bracelet before packing. We usually wash it with water once. After washing, we will check the quality. Packing and delivery.
