ʻO Isophthalic Orthophthalic Terephthalic Unsaturated Polyester No ka Pultrusion

ʻO nā resins polyester unsaturated i hoʻohana ʻia no ka pultrusion he ʻano o-phenylene a me m-phenylene. ʻOi aku ka maikaʻi o nā waiwai mechanical, toughness, he pale wela a me ke kūpaʻa i ka corrosion o ka resin ʻano Beta benzene. I kēia manawa, ʻoi aku ka nui o ka hoʻohana ʻana i ka home he ʻano o-phenylene, pono ke kaʻina hana hoʻoheheʻe pultrusion i ka hoʻohana ʻana i ka viscosity resin he haʻahaʻa, ʻo ka hoʻohana nui ʻana o ka resin polyester unsaturated a me ka epoxy resin a i ʻole ka epoxy resin i hoʻololi ʻia. ʻO ka resin polyester unsaturated i hoʻohana ʻia no ka pultrusion he ʻano o-phenylene a me m-phenylene, ʻoi aku ka maikaʻi o nā waiwai mechanical, toughness, he pale wela a me ke kūpaʻa i ka corrosion o ka resin ʻano m-phenylene. Eia nō naʻe, ʻaʻole hiki i ke kaʻina hana maoli i loaʻa i ka ʻenehana o kēia manawa o ka mea resin ke hoʻokō piha i nā koi o ke kaʻina hana hoʻoheheʻe pultrusion, no ka laʻana: aia kahi no ka hoʻomaikaʻi ʻana i ke kūpaʻa wela.
