FIBER POST USING ALKALI-PROOF GLASS FIBER AND MAKING METHOD OF IT

摘要

PURPOSE: Fiber post using alkali resistance and a manufacturing method of the same are provided to have less node capered to metal post, be easily removed, have optical transmittance rate by utilizing the beauty of visible light-cured resin and reduce the disadvantage of a fact that glass fiber has no impermeableness. CONSTITUTION: Fiber post using alkali resistance and a manufacturing method of the same comprises the following steps. After alkali resistance glass fiber formed with a coating layer is prepared, the coating layer is removed during the first heating process at a temperature of 350-450°C for 1-3 hours. After a silane solution is prepared, alkali resistance glass fiber is dipped into the silane solution for 45-75 seconds. The dipped alkali resistance glass fiber is carried out in the second heating process at a temperature of 100-120°C for 20-40 minutes. After the alkali resistance glass fiber is washed, the alkali resistance glass fiber is dried. The dried alkali resistance glass fiber is prepared to be dipped in visible light-cured resin in a vacuumed condition. The alkali resistance glass fiber is used to mold visible light-cured resin by using a light cured resin forming device.
