Silicone oil is a good liquid adjuvant, in many aspects has its irreplaceable role, also in the use of silicone rubber is inseparable from silicone oil.In the process of using silicone rubber, we often encounter some problems, which are found to be related to silicone oil.Is silicone oil used in silicone rubber only advantageous without disadvantageous?New Jia organic silicon to take you to understand
First, why does the mold silica gel appear less times of mold turning?Answer: Too much silicone oil is added in the process of mold making, which destroys the molecular weight of silica gel and thus causes the mold to be used less and not durable.
Two, why the mold silica gel will appear the phenomenon of tension difference?Answer: In the process of making molds, customers add a lot of silicone oil in order to reduce the viscosity of silica gel and make it easy to operate, which causes silica gel to become soft, non-tensile, tear strength to decrease and tension to become worse.
Three, why the silicone mold oil?Answer: The silicone mold appears oil because of the use of compound silicone oil in the production process, which contains white mineral oil.
Four, why will the silicone rubber mold produce acid and alkali resistance, aging resistance phenomenon?Answer: In the process of making molds, we do not recommend adding silicone oil. If added, it must not exceed 5%. Silicone oil will destroy the molecular weight of silica gel.
Five, pad printing silicone rubber head is not durable reason?Answer: There is a great relationship with the amount of silicone oil added to silicone rubber. The greater the amount of silicone oil added, the softer and less durable the rubber head is.
Silicone oil can destroy the molecular weight of silica gel.Silicone rubber and silicone oil belong to the category of silicone oxygen resin, from the structure of their difference is determined by the proportion of silicon atoms and groups in the molecular structure.The ratio of groups to silicon atoms in silicone rubber is nearly two to one, while the ratio of groups to silicon atoms in silicone oil is more than two to one.From the above, we can basically conclude that the higher the atomic weight of silicon, the closer it is to a solid, and the lower the atomic weight of silicon, the closer it is to a liquid (silicone oil does not condense).Many common problems are because by adding silicone oil to change the overall group of silicone rubber and the proportion of silicon atoms, thus reducing the hardness of silicone and the number of uses.So in the process of using silicone oil must pay attention to the problem of "quantity".There is to choose the strength of the manufacturer.
