Qhov sib txawv tseem ceeb ntawm Glyptal thiab Dacron yog Glyptal yog thermosetting polymer, hos Dacron yog thermoplastic polymer.
Ob leeg Glyptal thiab Dacron yog cov khoom siv polymer. Cov no yog cov npe lag luam ntawm polymers. Lawv muaj cov tshuaj sib txawv thiab cov khoom sib txawv, thiab. Yog li ntawd, lawv cov ntawv thov hauv kev lag luam kuj txawv ntawm ib leeg.
Glyptal yog dab tsi?
Glyptal yog ib hom alkyd uas muaj polyester nrog fatty acids. Glyptal yog lub npe lag luam ntawm cov khoom siv polymer uas yog tsim los ntawm glycerol thiab phthalic acid. Glyptal tuaj yeem siv los hloov cov xim dub-xim Copal resins. Glyptal tuaj yeem tsim alkyd varnishes nrog cov xim daj. Txawm li cas los xij, Glyptal yog ib qho qub version ntawm alkyds uas peb siv niaj hnub no. Kev siv loj ntawm Glyptal yog ua tus neeg sawv cev txheej txheej. Ntxiv mus, nws yog siv los ua cov khoom siv khi, cement, thiab lwm yam.
Daim duab 01: Tus Qauv ntawm Alkyd
Cov khoom siv polymer no tsis tshwm sim ib txwm muaj; Nws yog ib tug hluavtaws polymer. Peb tuaj yeem categorize nws li cross-linked polymer vim hais tias nws muaj ib tug network qauv nrog ntau crosslinks ntawm polymer chains. Cov saw hlau polymer no yog ua los ntawm glycerol molecules. Raws li nws cov khoom, Glyptal yog thermosetting polymer.
Dacron yog dab tsi?
Dacron yog lub npe lag luam ntawm polyethylene terephthalate. Lub npe lag luam no yog siv feem ntau hauv Asmeskas. Qee zaum, nws yog abbreviated li PET lossis PETE. Nws yog cov tswv cuab feem ntau ntawm cov thermoplastic polymers ntawm polyesters. Tsis tas li ntawd, cov khoom siv polymer no muaj txiaj ntsig zoo hauv kev tsim cov fibers rau khaub ncaws, ntim khoom noj thiab dej haus, tsim cov resins, thiab lwm yam. Dacron polymer cov khoom muaj cov khoom ntawm ethylene terephthalate monomers txuas rau ib leeg ntawm polymerization. Chav tsev rov ua dua yog C10H8O4 Ntxiv mus, peb tuaj yeem rov ua cov khoom no yooj yim.
Daim duab 02: Rov ua dua Chav ntawm Dacron Polymer Khoom
Feem ntau, peb tuaj yeem categorize Dacron ua cov khoom siv semicrystalline. Tab sis, nws tuaj yeem tshwm sim hauv lub xeev amorphous thiab. Yog li ntawd, nws tuaj yeem muaj nyob hauv ob lub xeev opaque thiab pob tshab. Lawm, nws yog cov khoom tsis muaj xim, thiab nws tuaj yeem nruj lossis ib nrab nruj nyob ntawm txoj kev tsim khoom. Txawm li cas los xij, nws yog qhov hnyav heev. Tsis tas li ntawd, cov khoom no ua rau muaj kev cuam tshuam zoo rau cov dej noo thiab cov kuab tshuaj. Tsis tas li ntawd, qhov paub zoo tshaj plaws ntawm Dacron yog nws cov viscosity intrinsic.
Qhov txawv ntawm Glyptal thiab Dacron yog dab tsi?
Ob leeg Glyptal thiab Dacron yog cov khoom siv polymer. Cov no yog cov npe lag luam ntawm polymers. Lawv muaj cov tshuaj sib txawv thiab cov khoom sib txawv. Yog li ntawd, lawv cov ntawv thov hauv kev lag luam kuj txawv ntawm ib leeg. Qhov sib txawv tseem ceeb ntawm Glyptal thiab Dacron yog Glyptal yog thermosetting polymer, hos Dacron yog thermoplastic polymer. Tsis tas li, Glyptal yog tsim los ntawm glycerol thiab phthalic acid thaum Dacron yog tsim los ntawm ethylene terephthalate.
Ntxiv mus, Glyptal yog qhov tseem ceeb ua tus neeg sawv cev txheej txheej, cov khoom siv khi, cov cement, thiab lwm yam. Dacron, ntawm qhov tod tes, yog qhov tseem ceeb hauv kev tsim cov fibers rau khaub ncaws, ntim khoom noj thiab dej haus, ntau lawm. ntawm resins, thiab lwm yam.
Hauv qab no yog cov lus qhia txog qhov sib txawv ntawm Glyptal thiab Dacron.
Summary – Glyptal vs Dacron
Ob leeg Glyptal thiab Dacron yog cov khoom siv polymer. Cov no yog cov npe lag luam ntawm polymers. Lawv muaj cov tshuaj sib txawv thiab cov khoom sib txawv. Yog li ntawd, lawv cov ntawv thov hauv kev lag luam kuj txawv ntawm ib leeg. Qhov sib txawv tseem ceeb ntawm Glyptal thiab Dacron yog Glyptal yog cov thermosetting polymer, hos Dacron yog thermoplastic polymer.
