Unsaturated polyester cob, kuj paub los ntawm cov lus Askiv acronymUPR, yog ib qho yooj yim luam tawm kua polymer uas, ib zaug kho (hla-txuas nrog styrene, los ntawm kev siv cov tshuaj tshwj xeeb, organic peroxides, hu ua hardeners), khaws cov khoom zoo hauv cov pwm.Cov khoom thiaj li pom tau tias muaj zog tshwj xeeb thiab durability yam ntxwv.Unsaturated polyester resins feem ntau yog siv ua ke nrog cov khoom siv ntxiv xws liiav fibers, uas muab lub neej rau FRP (ib qho lus piav qhia los ntawm lus Askiv), polyester reinforced nrog iav fibers, paub zoo nrog lub npe ntawmfiberglass.Nyob rau hauv cov ntaub ntawv no, polyester resin muaj ib tug array muaj nuj nqi, channeling lub zog thov mus rau cov khoom mus rau lub fibers uas yog tsim los tiv thaiv cov rog, ua kom lub zog thiab tsis txhob tawg ntawm cov khoom.Ua ke nrog los yog cais los ntawm cov iav fibers, cov kuaunsaturated polyester cobtej zaum yuav ntim nrog hmoov los yog granules ntawm ntau qhov ntau thiab tsawg, uas muab cov ntsiab lus ntawm rigidity thiab kuj cov yam ntxwv, los yog zoo nkauj zoo nkauj rau cov imitation ntawm ntuj marble thiab pob zeb, tej zaum yuav zoo dua.Covunsaturated polyester cobyog siv nrog kev vam meej nyob rau hauv ntau lub lag luam sectors, xws li nyob rau hauv watersports rau creation ntawm windsurfers thiab lom zem nkoj.Qhov nopolymertau nyob rau hauv nruab nrab ntawm ib tug tiag tiag kiv puag ncig nyob rau hauv lub nkoj kev lag luam, vim hais tias nws muaj peev xwm muab tau zoo ua yeeb yam thiab ib tug heev yooj yooj yim ntawm kev siv.Covunsaturated polyester resinskuj tseem siv tau rau hauv kev lag luam automotive (kev lag luam tsheb), rau lawv cov kev tsim qauv zoo, lub teeb yuag, cov nqi qis dua thiab cov khoom siv zog.Cov khoom siv no kuj tseem siv rau cov tsev, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov hobs rau cookers, vuas rau lub ru tsev, chav dej accessories, tab sis kuj cov kav dej, ducts thiab tso tsheb hlau luam.
UNSaturated POLYESTER RESINS CHARACTERISTICS:
Lub ntsiab nta ntawm unsaturated polyester resins muaj xws li: Kua, nyob rau hauv lawv siv:
● Tsis zoo linear shrinkage.
● Zoo heev wettability ntawm cov fibers thiab nqi.
● Txias cross-linking los ntawm kev sib ntxiv ntawm hardener.
● Kev txo qis ntawm cov nyhuv ntawm sagging nyob rau hauv ntsug stratification (thixotropic zog).
Khoom, tom qab sib txuas sib txuas:
● Exceptional lightness.
● Rigidity.
● Zoo rwb thaiv tsev hluav taws xob.
● Dimensional stability tiv thaiv kub hloov.
● Lub zog ntau dua / qhov hnyav dua li cov hlau.
● Resistance rau tshuaj.
● Zoo heev nto tiav.
● Kev tiv thaiv dej.
● Resistance hnav thiab thiab kub kub.
● Zoo mechanical resistance.
UNSaturated POLYESTER RESIN APPLICATIONS:
Kev siv ntawm unsaturated polyester resin muaj ntau yam.Polyester resins nyob rau hauv qhov tseeb sawv cev rau ib qho ntawm cov ntsiab lus tseeb siv nyob rau hauv ntau yam kev lag luam.Qhov tseem ceeb tshaj plaws, nrog rau cov lus piav qhia saum toj no, yog:
● Cov ntaub ntawv sib xyaw.
● Cov xim ntoo.
● Pav ca laminated panels, corrugated panels, ribbed panels.
● Gel tsho tiv no rau lub nkoj, tsheb thiab chav dej fixtures.
● Coloring pastes, fillers, stucco, putties thiab tshuaj anchorings.
● Self-extinguishing composite cov ntaub ntawv.
● Quartz, marble thiab dag cement.
