Ọdịmma Liquid Polyester Resin adịghị mma maka Fiberglass
"Polyester" bụ klas nke ogige polymer nwere ester bond nke dị iche na resins dị ka phenolic na epoxy resins. A na-emepụta ogige polymer a site na mmeghachi omume polycondensation dị n'etiti dibasic acid na mmanya dibasic, na mgbe ngwakọta polymer a nwere njikọ abụọ na-adịghị edozi, a na-akpọ ya polyester unsaturated, na polyester a na-adịghị edozi na-agbaze na monomer nke nwere ike ịbụ polymerised ( n'ozuzu styrene).
A na-agbaze polyester a na-adịghị mma na monomer (na-emekarị styrene) nke nwere ikike polymerise, na mgbe ọ na-aghọ mmiri mmiri viscous, a na-akpọ ya resin polyester na-adịghị edozi (Unsaturated Polyester Resin ma ọ bụ UPR maka mkpụmkpụ).
Enwere ike ịkọwa resin polyester na-adịghị mma dị ka mmiri mmiri viscous kpụrụ site na polycondensation nke dibasic acid nwere mmanya na-egbu egbu nwere dibasic acid na-adịghị mma ma ọ bụ mmanya dibasic n'ime ngwongwo polymer linear gbazere na monomer (na-abụkarị styrene). Resin polyester na-adịghị mma, nke mejupụtara 75 pasent nke resin anyị na-eji kwa ụbọchị.
