Unsaturated polyester resin ndiyo inonyanya kushandiswa mhando ye thermosetting resin, iyo inowanzoita mutsara wepolymer komboni ine ester bond uye unsaturated kaviri zvisungo zvinoumbwa ne condensation yeunsaturated dicarboxylic acid ine diols kana saturated dicarboxylic acid ine unsaturated diols. Kazhinji, iyo polyester condensation reaction inoitwa pa190-220 ℃ kusvika iyo inotarisirwa asidhi kukosha (kana viscosity) yasvika. Mushure mekunge iyo polyester condensation reaction yapera, imwe huwandu hwevinyl monomer inowedzerwa ichipisa kugadzira viscous fluid. Iyi polima mhinduro inonzi unsaturated polyester resin.
Unsaturated polyester resin yakawana budiriro huru muminda yakawanda yemaindasitiri, senge mukugadzirwa kwemhepo yekusevha nemhepo uye mayacht mumitambo yemvura. Iyi polymer yagara iri pamusimboti weshanduko yechokwadi muindasitiri yekuvaka ngarava, sezvo ichigona kupa kuita kwakanakisa uye kuchinjika kwakanyanya mukushandisa.
Unsaturated polyester resins anowanzo shandiswa muindasitiri yemotokari nekuda kwedhizaini yavo yakasiyana-siyana, huremu huremu, mutengo wakaderera wehurongwa, uye kuderera kwesimba remagetsi.
Ichi chinyorwa chinoshandiswawo muzvivakwa, kunyanya mukugadzira midziyo yekubikira, zvitofu, mataira edenga, zvishongedzo zvekugezera, pamwe nemapombi nematangi emvura.
Iko kushandiswa kweiyo unsaturated polyester resin kwakasiyana. Iyo polyester resins inomiririra imwe yemhedziso
makemikari anoshandiswa mumhando dzakasiyana-siyana dzemaindasitiri. Zvinonyanya kukosha, pamwe chete nezviri kuratidzwa pamusoro apa, ndezvi:
* Composite zvinhu
* Pendi dzehuni
* Flat laminated panels, corrugated panels, ribbed panels
* Gel jasi rezvikepe, mota uye yekugezera zvigadziriso
* Kupenda paste, mafirita, stucco, putties uye makemikari anchorings
* Inodzima-inodzima inoumbwa zvinhu
* Quartz, marble uye simende yekugadzira
