Diamond crystal facets plus liquid silicone molding   Liquid silicone rubber is a vinyl-containing siloxane as the base polymer is polyethylene containing a poly Si-H bond to make a silicone crosslinker in the presence of a platinum catalyst at room temperature or under heating to deposit United curing a class of silicon material . Liquid silicone rubber based adhesive , mainly comprising two or more poly vinyl diorganosiloxane .   Figure - silicone rubber     Add molding liquid silicone (LSR) is a high -grade silicone rubber varieties and condensation of a liquid silicone rubber, liquid silicone picture , in general, before vulcanization is somewhat toxic, because before vulcanization is a mixture of various substances , vulcanized crosslinked .     Plus silicone molding temperature range -65 ° C - 200 ° C for long-term use and to maintain its softness under elastic properties , have excellent electrical properties and chemical stability, water resistance, ozone resistance, resistance to weathering , non-corrosive, physiologically inert , non-toxic , odorless , low linear shrinkage , easy to operate LSR also has a process is simple , low -cost outstanding advantages .     Plus liquid silicone molding characteristics are as follows:     ① To add molding silicone with good operating performance.     ② silica and molding flow better , low viscosity for easy operation.     ③ plus silicone molding shrinkage smaller the better.     ④ add molding silicone tension better .     ⑤ made ​​out of silicone mold can not be deformed .     ⑥ plus hardness silicone molding to fit the product to use.     ⑦ temperature, turn mode more often , life is longer, acid and alkali resistance to aging .     Diamond drilling and molding section of the Appearance transparent liquid silicone gel , good fluidity . For rhinestones , cut diamond , mold machining soft amber , crystal jewelry, crafts . Was two-component high-strength , high transparency, high tear resistance , soft, strong bonding, shrinkage , operating time up to 5 hours of new silicone rubber (silicone ) .     Imitation gemstones to use special plastic mold     A hybrid : the gum base and curing agent are mixed in a weight ratio of 10:1 and mixed manually or using the device.     2 , degassing : glue mixture before filling the mold should be degassed. Small when used in a vacuum drier under vacuum , the volume of plastic material can be increased 4-5 times ( foam ) , and therefore , the volume of the container to be degassed 4-5 times larger than the volume of gel , after a few minutes gel volume returns to normal when the escape of air bubbles when the surface ( about 10 minutes ) to complete .     3 , surface treatment : surface mold surface or potting compound to be used in contact with liquid paraffin as a release agent .     4 , curing and stripping : Mixed degassed plastic material placed 120 ± 5 ° C bake 30 minutes curing ,60-70 ° C oven for 2-3 hours curing , room temperature curing time 24Hr, temperature and time can be cured according to process conditions.
