Qhov sib txawv tseem ceeb ntawm neoprene thiab chloroprene yog neoprene yog polymer, hos chloroprene yog monomer rau neoprene ntau lawm.
Neoprene yog ib hom roj hmab hluavtaws. Chloroprene yog lub npe nrov rau cov compound 2-chlorobuta-1, 3-diene, muaj cov tshuaj formula CH2=CCl-CH=CH2. Neoprene thiab chloroprene yog hom khoom siv roj hmab hluavtaws. Neoprene yog ib qho polymer ua los ntawm chloroprene.
Neoprene yog dab tsi?
Neoprene yog ib hom roj hmab hluavtaws. Nws yog tsim los ntawm polymerization ntawm chloroprene. Cov khoom siv no muaj cov tshuaj lom neeg ruaj khov thiab tuaj yeem tswj tau nws qhov yooj yim rau qhov kub thiab txias. Muaj ob txoj hauv kev uas tib neeg muag cov khoom no; Cov khoom siv roj hmab thiab 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 tug neeg 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.
Daim duab 01: Kev dhia dhia ua si tau siv Neoprene
Cov kev siv dav dav ntawm neoprene suav nrog kev tsim cov gaskets, hoses, thiab cov txheej tiv thaiv corrosion. Nyob rau hauv lub tshav pob ntawm civil engineering, cov neeg siv nws raws li ib tug load-bearing puag, feem ntau yog nruab nrab ntawm ob prefabricated reinforced pob zeb ntsiab lus los yog steel daim hlau. Tsis tas li ntawd, peb tuaj yeem siv cov khoom siv no los ua cov khaub ncaws tiv thaiv rau cov dej hauv dej. Tsis tas li ntawd, nws muaj txiaj ntsig zoo hauv kev lag luam automotive los ua lub rooj zaum tsheb, thiab lwm yam.
YChloroprene yog dab tsi?
Chloroprene yog lub npe nrov rau cov compound 2-chlorobuta-1, 3-diene muaj cov tshuaj formula CH2=CCl−CH=CH2. Nws yog cov kua uas tsis muaj xim thiab tsis hloov pauv uas muaj txiaj ntsig tshwj xeeb yog monomer rau kev tsim cov polychloroprene polymer, uas yog ib hom roj hmab hluavtaws. Cov khoom siv polymer no hu ua neoprene.
Daim duab 02: Lub Chloroprene Monomer Chemical Structure
Nws muaj peb kauj ruam pab tsim cov tshuaj chloroprene: chlorination, isomerization ntawm ib feem ntawm cov khoom ntws, thiab dehydrochlorination. Txawm li cas los xij, txog xyoo 1960, cov txheej txheem acetylene tau siv los tsim cov tshuaj no. Cov txheej txheem no suav nrog cov dimerization ntawm acetylene kom tau vinyl acetylene tom qab ua ke nrog hydrogen chloride kom tau 4-chloro-1, 2-butadiene.
Kev sib raug zoo ntawm Neoprene thiab Chloroprene yog dab tsi?
- Neoprene thiab chloroprene yog hom khoom siv roj hmab hluavtaws.
- Ntxiv mus, neoprene yog ib qho polymer ua los ntawm chloroprene.
Qhov txawv ntawm Neoprene thiab Chloroprene yog dab tsi?
Neoprene yog ib hom roj hmab hluavtaws. Chloroprene yog lub npe nrov rau cov compound 2-chlorobuta-1, 3-diene muaj cov tshuaj formula CH2=CCl−CH=CH2. Qhov sib txawv tseem ceeb ntawm neoprene thiab chloroprene yog neoprene yog cov khoom siv polymer, thaum chloroprene yog monomer rau neoprene ntau lawm. Ntxiv mus, neoprene yog tsim los ntawm dawb radical polymerization ntawm chloroprene, whereas chloroprene yog tsim los ntawm cov txheej txheem acetylene los yog ib tug niaj hnub txheej txheem uas koom nrog chlorination, isomerization ntawm ib feem ntawm cov khoom kwj, thiab dehydrochlorination.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm neoprene thiab chloroprene hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Neoprene vs Chloroprene
Neoprene thiab chloroprene yog hom khoom siv roj hmab hluavtaws. Neoprene yog ib qho polymer ua los ntawm chloroprene. Qhov sib txawv tseem ceeb ntawm neoprene thiab chloroprene yog neoprene yog cov khoom siv polymer, thaum chloroprene yog monomer rau neoprene ntau lawm.
