Qhov txawv ntawm Lycra thiab neoprene yog tias lycra yog ib qho elastic fiber thaum lub neoprene yog ib hom roj hmab hluavtaws.
Ob leeg lycra thiab neoprene yog cov khoom siv polymer. Yog li ntawd, lawv muaj ib tug loj tus naj npawb ntawm rov qab units uas sawv cev rau lub monomers, uas undergo polymerization nyob rau hauv thiaj li yuav tsim no polymer. Ob leeg yog cov khoom siv hluavtaws, tab sis muaj qhov sib txawv ntawm lawv. Sib nrug los ntawm qhov sib txawv tseem ceeb saum toj no, lwm qhov sib txawv tseem ceeb ntawm Lycra thiab neoprene yog tias Lycra muaj qhov tshwj xeeb elasticity thaum Neoprene muaj qhov tshwj xeeb inertness.
YLycra yog dab tsi?
Lycra yog cov khoom siv hluavtaws hluavtaws uas los ntawm cov fibers elastic. Nws yog qhov paub zoo rau nws qhov tshwj xeeb elasticity. Tsis tas li ntawd, nws yog copolymer uas muaj polyether thiab polyurea. Lwm lub npe rau tib yam khoom yog Spandex. Txawm li cas los xij, qee cov neeg hu nws Elastane. Lub teeb yuag thiab ze ze qhov pom ntawm cov khoom siv fiber ntau no ua rau nws muaj cov khoom xyaw hauv peb cov khaub ncaws.
Muaj plaub txoj hauv kev los tsim cov fibers no. Lawv yog yaj extrusion, tshuaj tiv thaiv spinning, tov qhuav spinning, thiab tov ntub spinning. Txawm li cas los xij, kwv yees li 95% ntawm cov neeg tsim khoom siv cov txheej txheem qhuav spinning. Ntxiv mus, tag nrho cov txheej txheem no suav nrog kev tsim ua ntej-polymer los ntawm reacting cov monomers ua thawj kauj ruam.

Cov ntawv thov loj ntawm cov khoom siv polymer no yog vim nws elasticity thiab lub zog. Cov cuab yeej tseem ceeb tshaj plaws ntawm lycra yog nws lub peev xwm rov qab mus rau qhov qub zoo tom qab ncab, thiab ziab sai dua li cov ntaub zoo tib yam. Cov ntawv thov muaj nyob rau hauv cov ris tsho hnav ris tsho, cov ris tsho compression, cov khaub ncaws zoo li tus (xws li lub kaus mom khiab mis, txhawb nqa hose, phais hose, thiab lwm yam) thiab hauv cov khoom vaj khoom tsev.
Neoprene yog dab tsi?
Neoprene yog ib hom roj hmab hluavtaws. Nws tsim los ntawm polymerization ntawm chloroprene. Cov khoom siv no muaj cov tshuaj lom neeg ruaj khov zoo, thiab nws tuaj yeem tswj tau nws qhov kev hloov pauv mus rau qhov kub thiab txias. Muaj ob txoj hauv kev uas tib neeg muag cov khoom no; raws li cov roj hmab khoom lossis hauv daim ntawv latex.
Ntxiv mus, txoj kev tsim khoom ntawm cov khoom no yog dawb radical polymerization ntawm chloroprene. Rau qhov pib ntawm kev tsim khoom, peb xav tau potassium persulfate. Ua ntej, nws tsim ib tus kheej polymer strands. Tom qab ntawd, peb tuaj yeem txuas cov tib neeg cov polymer strands siv Bi-functional nucleophiles (muaj ob pawg ua haujlwm), hlau oxides thiab thioureas.

Ntawm cov ntawv thov ntawm cov khoom siv no, cov ntawv thov dav dav suav nrog kev tsim cov gaskets, hoses, thiab coatings-resistant coatings. Nyob rau hauv lub tshav pob ntawm civil engineering, cov neeg siv nws raws li ib tug load bearing puag, feem ntau ntawm ob prefabricated reinforced pob zeb ntsiab lus los yog steel daim hlau. Ntxiv rau qhov ntawd, peb tuaj yeem siv cov khoom siv no los ua cov khaub ncaws tiv thaiv rau cov dej hauv dej. Sib nrug los ntawm qhov ntawd, nws muaj txiaj ntsig zoo hauv kev lag luam automotive los ua lub rooj zaum tsheb, thiab lwm yam.
Qhov txawv ntawm Lycra thiab Neoprene yog dab tsi?
Lycra yog cov khoom siv hluavtaws hluavtaws uas los ntawm cov fibers elastic, thiab Neoprene yog ib hom roj hmab hluavtaws. Qhov sib txawv tseem ceeb ntawm lycra thiab neoprene yog tias lycra yog ib qho elastic fiber thaum neoprene yog ib hom roj hmab hluavtaws. Lwm qhov txawv ntawm lycra thiab neoprene yog tias lycra yog ib qho copolymer ntawm polyether-polyurea thaum neoprene yog homopolymer ntawm chloroprene.
Ntxiv mus, lycra muaj qhov tshwj xeeb elasticity thaum neoprene muaj qhov tshwj xeeb inertness. Thaum xav txog cov txheej txheem ntau lawm, rau lycra, muaj plaub txoj kev sib txawv xws li yaj extrusion, tshuaj tiv thaiv spinning, tov qhuav spinning, thiab tov ntub spinning. Tab sis rau neoprene, nws yog dawb radical polymerization ntawm chloroprene.
Cov hauv qab no qhia cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm lycra thiab neoprene.
Summary – Lycra vs Neoprene
Ob leeg Lycra thiab neoprene yog cov khoom siv hluavtaws polymer. Txawm li cas los xij, lawv sib txawv ntawm ib leeg hauv ntau yam. Qhov sib txawv tseem ceeb ntawm Lycra thiab neoprene yog tias lycra yog ib qho elastic fiber thaum lub neoprene yog ib hom roj hmab hluavtaws.
