Abstract:
     In preparation method of slender glass (such as light guide prefabricated component) in which SiO2 is main composition, the invention uses following technique in order to simplify shaped pressing procedure: the glass powder will be prepressed when it is feeded into a mould and the prepressed powder will be pressed after the feeding is finished, the porosint can be obtained. The procedure and measures can keep stable shape of flexible pipe in the condition of the feeding. A screw feeder or several coaxial or parallel screw feeders are used in feeding. The radial material can form wanted porosint. The invention describes also the various moulds for preparing tubular and rod porosints.
