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 ma ke ʻano he o-phenylene a me ka m-phenylene ʻano, ʻoi aku ka maikaʻi o ka resin type m-phenylene, ʻoi aku ka paʻakikī, ke kūpaʻa wela a me ka pale ʻana i ka corrosion. Eia nō naʻe, ʻaʻole hiki ke hoʻokō pono i nā koi o ke kaʻina hana pultrusion i loaʻa i ka ʻenehana i kēia manawa o ka mea resin, no ka laʻana: ke kūpaʻa wela aia kahi wahi e hoʻomaikaʻi ai.
