Silicone rubber is divided into hot vulcanisation type (high temperature vulcanisation silicone HTV), room temperature vulcanisation type (RTV), of which the room temperature vulcanisation type is divided into polycondensation reaction type and addition reaction type.
Silicone rubber can be mixed without plasticising, and is generally operated by an opening machine. Mixing to maintain a low roller temperature (not more than 50 ℃), a short period of time. Raw rubber to join the first package of the front (slow) roll, mixing and eating powder to package the back of the roll, so it is appropriate to operate on both sides. After the package roll can be added to the matching agent, to be mixed evenly, all the rubber package roll and smooth surface can be. Silicone rubber texture is soft, mixing and cutting with a putty knife. After mixing the rubber material to be after a certain period of time (> 24h) parking, in order to facilitate the dispersion of the matching agent, must be used before refining. Mixing rubber should be used with refining, too long, vulcanised rubber performance will be reduced.
