Abstract

Patente de Invenção: "MEMBRANA POLIMéRICA DE SUPORTE ESTRUTURAL". Em escavações, como minas, suportes são necessários para evitar a queda de rochas. As vigas estruturais provêem o suporte principal na escavação para evitar quedas de pedras maiores. No entanto, entre as vigas principais, quedas de rochas menores podem ainda ocorrer. Para prover suporte estrutural entre as vigas principais, uma membrana polimérica de suporte estrutural pode ser aplicada. A membrana inclui um polímero que é o produto da reação de monómero, um iniciador, e opcionalmente um agente de reticulação; e um agente de auto-extinção. A membrana pode ser aplicada por pulverização, escova, ou rolo.Invention Patent: "STRUCTURAL SUPPORT POLYMERIC MEMBRANE". In excavations, such as mines, supports are needed to prevent falling rocks. Structural beams provide the main support for excavation to prevent falls from larger stones. However, among the main beams, falls from smaller rocks can still occur. To provide structural support between the main beams, a polymeric structural support membrane can be applied. The membrane includes a polymer which is the product of the monomer reaction, an initiator, and optionally a crosslinking agent; and a self-extinguishing agent. The membrane can be applied by spray, brush, or roller.
