Analysis of the reasons for the shiny and oily surface of high-temperature vulcanized silicone products!diy silicone pacifier clip Vendor

　　When silicone products manufacturers vulcanize miscellaneous pieces of silicone products with darker colors at high temperature, sometimes the products will seep oil and become shiny, and oil spots will stick together. The most likely problem is the appearance of the product. On the other hand The auxiliary materials added in it also have certain considerable factors, such as vulcanizing agent, mold release agent, color glue and flavor, quantum fraction, etc., and have you analyzed the influence of mold release agent on silicone products?

　　Shining, watermarking, oil spots on the surface of polluted molds, etc., many production technicians are at a loss, and usually because of the vulcanization of other relatively low-demand products that do not require secondary processing, there is no mold release water. The problem is that we can't always find the reason. In fact, it is the problem of mold release water. It's just that when the color of silicone products is light, we can't see it with the naked eye. In this case, we should understand and analyze whether there is a problem with mold release water.

　　1. Introduction of silicone external mold release agent:

　　For such silicone rubber products, the external mold release agent must be processed and refined by imported raw materials, that is, in order to achieve good mold release effect, no residue, and no sediment in addition to high-quality silicone rubber products external mold release agent, but also In the vulcanization of silica gel, it can quickly achieve the mold release effect of mold release cleaning, and can increase production efficiency and reduce mold maintenance costs, and can also maintain excellent lubrication between metal and non-metal.

　　Second, the standard release agent performance indicators

　　Appearance, specific gravity, ALKALI: PH, ionicity, dilution solvent, recommended ratio

　　Light yellow to transparent liquid, 1.01±0.02, 9-10, non-ionic, water, 15-30 times

　　3. Advantages of using release agent

　　It must be suitable for all products of silica gel. It can still retain its original characteristics when the temperature changes greatly, and it is not easy to be oxidized and not easy to react with most chemical substances. Excellent storage stability, easy to handle, and still very stable when the mold temperature is high. No colloid or residual substances are left to cause pollution on the surface of the product, saving costs and improving product quality.

　　4. External use method

　　After directly diluting this product with water, spray it on the surface of the mold; the specific dilution ratio should be selected according to the difficulty of molding and demolding the silicone product. The surface produces undesirable appearance phenomena such as whitening, cracks, watermarks, and oil spitting.

　　Five, matters needing attention

　　1. When using it for the first time, please clean the mold and remove other mold release agent residues to ensure the effect of use.

　　2. When the dilution ratio is not enough, it may cause slight oil spitting on the appearance of very few silicone products.

　　3. Please store it in a cool place indoors, do not expose it to the sun for a long time. Generally, the effective retention period of mold release water is 12 months.
