People use silicone process often encounter some problems, but many of these issues are related to silicone oil. As we all know, silicone is a good liquid adjuvants, in many places to play a key role also in the process of using silica gel silicone oil can not be separated. But contrast, the benefits of silicone silicone products also had a negative effect, the following are a few problems in the process of using silica gel:
The question: Why is there less silicone mold turning model number?
ANSWER: In the mold making process of adding too much silicone oil, silicone oil destroys the molecular weight of the silica so that the mold appears to reduce the frequency of use, not durable and so on.
Question two: Why silicone mold phenomenon appears Rally difference?
ANSWER: The customer in the production process of the mold in order to reduce the viscosity of silica, silica gel is easy to operate so that added a lot of oil, which results in a silica gel softens, intolerance pull, tear strength decreases, pull deteriorated.
Question three: Why silicone mold appear Maoyou situation?
ANSWER: silicone mold appear Maoyou is because the production process used composite type silicone oil, which contains a white mineral oil.
Question 4: Why silicone mold appears not acid, intolerant aging phenomenon?
ANSWER: In the process of making molds is not recommended to add oil, if added to ensure that not more than 5%, because the silicone oil will destroy the molecular weight silicone.
Question 5: printing silicone rubber head not durable reason?
ANSWER: The amount of silica added to the silicone oil has a great relationship, the greater the amount of silicone oil, the less soft plastic head more durable.
A lot of problems not enumerated, but the above problems can be roughly summed up the reason is that silicone oil will destroy the molecular weight silicone. If there is enough understanding will understand, silicone and silicone belong silicone resin (the term "resin" is provided by industry Encyclopedia) category, from the structure of their difference is dependent on the molecular structure of the silicon atoms of silicone products and the proportion of groups. The proportion of the group and a silicon atom silicone close to 2: 1, while the proportion of silicone oil groups and silicon atoms> 2: 1. Therefore, a conclusion can be drawn, the higher the closer the solid silicon atomic weight, the less silicon atomic weight closer liquid (silicone oil is not condensation). Many common problems are due to the addition of the silicone oil change group overall proportion of silica and silicon atoms thereby reducing the hardness and frequency of use of silica gel. Therefore, use silicone process must pay attention to the "quantity" issue.
Another aspect of the manufacturers of silicone oil due to the different materials and processes will result in the product quality of the above differences, the market will be even shoddy phenomenon. The use of silicone oil in time to pay attention to these cases.
