Hauv lub ntiaj teb loj heev ntawm cov polymers hluavtaws, lo lus "polyester" yog qhov txhia chaw. Txawm li cas los xij, nws tsis yog ib yam khoom siv tab sis yog ib tsev neeg ntawm cov polymers uas muaj cov yam ntxwv sib txawv heev. Rau cov engineers, cov chaw tsim khoom, cov neeg tsim qauv, thiab cov neeg nyiam DIY, nkag siab txog qhov sib txawv tseem ceeb ntawmpolyester uas muaj roj ntauthiabpolyester tsis muaj rojyog qhov tseem ceeb heev. Qhov no tsis yog tsuas yog kev kawm txog chemistry xwb; nws yog qhov txawv ntawm lub raj mis dej ruaj khov, lub cev tsheb ua si zoo nkauj, cov ntaub ci ntsa iab, thiab lub cev nkoj ruaj khov.

Phau ntawv qhia no yuav piav qhia txog ob hom polymer no kom meej. Peb yuav kawm txog lawv cov qauv tshuaj lom neeg, tshawb nrhiav lawv cov yam ntxwv, thiab piav qhia txog lawv cov kev siv feem ntau. Thaum kawg, koj yuav paub qhov txawv ntawm lawv nrog kev ntseeg siab thiab nkag siab tias cov khoom twg yog qhov tsim nyog rau koj cov kev xav tau tshwj xeeb.

Saib Ib Zaug: Qhov Txawv Tseem Ceeb

Qhov sib txawv tseem ceeb tshaj plaws yog nyob rau hauv lawv cov pob txha caj qaum thiab lawv kho li cas (tawv rau hauv daim ntawv khov kho kawg).

·Polyester tsis muaj roj (UPE): Muaj cov khoom sib txuas ob npaug (C = C) hauv nws lub pob txha caj qaum. Nws feem ntau yog cov kua roj uas xav tau cov monomer reactive (xws li styrene) thiab cov catalyst kom kho tau ua cov yas ruaj khov, sib txuas, thermosetting. Xav txogCov Yas Uas Muaj Fiberglass (FRP).

· Cov Polyester Uas Muaj Roj: Tsis muaj cov kev sib txuas ob npaug no; nws cov saw hlau yog "saturated" nrog cov hydrogen atoms. Nws feem ntau yog cov thermoplastic khov kho uas mos thaum cua sov thiab tawv thaum txias, tso cai rau kev rov ua dua tshiab thiab rov ua dua tshiab. Xav txog lub raj mis PET lossiscov xov polyesterrau khaub ncaws.
