SEALANT FOR POLYMERISATION MOULD (VERSIONS), LINER OF ELASTIC POLYMER MATERIAL (VERSIONS), AND DEVICE FOR PRODUCING POLYMER SHEET MATERIALS (VERSIONS)

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to equipment intended for production of polymer sheet materials, namely, organic glass sheet and its elements. Proposed sealant represents a frame with polymerisation mix inlet arranged on one side of said frame. Note here that said frame comprises stiff flat substrate and liner made from elastic polymer material. Note also that said liner is made up of tube with two parallel tabs arranged along tube outer surface. Said tabs envelopes said stiff substrate over its outer diametre. ^ EFFECT: organic glass with preset sizes, ruling out nonuniform thickness of edges and reduces amount of wastes. ^ 11 cl, 5 dwg
