Isophthalic Orthophthalic Terephthalic Unsaturated Polyester No ka Pultrusion

Hoʻohana ʻia nā resins polyester unsaturated no ka pultrusion he ʻano o-phenylene a me m-phenylene.ʻOi aku ka maikaʻi o ka ʻano ʻano resin beta benzene, ʻoi aku ka paʻakikī, ka pale wela a me ka pale ʻana i ka corrosion.I kēia manawa, ʻoi aku ka nui o ka hoʻohana ʻana i ka home he ʻano o-phenylene, pono ke kaʻina hana pultrusion i ka hoʻohana ʻana i ka resin viscosity haʻahaʻa, ʻo ka hoʻohana nui ʻana i ka resin polyester unsaturated a me ka resin epoxy a i ʻole ka resin epoxy i hoʻololi ʻia.ʻO ka resin polyester unsaturated i hoʻohana ʻia no ka pultrusion ʻo ia ka o-phenylene a me ka m-phenylene type, ʻoi aku ka maikaʻi o ka resin type m-phenylene, ʻoi aku ka paʻakikī, ka wela a me ka pale ʻana i ka corrosion.Eia naʻe, ʻaʻole hiki ke hoʻokō pono i nā koi o ke kaʻina hana pultrusion i loaʻa i ka ʻenehana i kēia manawa o ka resin, no ka laʻana: ke kū ʻana i ka wela aia kahi wahi no ka hoʻomaikaʻi.
