KeyDifference - Neoprene vs Nitrile Rubber
Ntau cov khoom siv roj hmab muaj feem xyuam rau ntau hom roj hmab hluavtaws vim ntau yam laj thawj. Qhov kev thov rau cov roj hmab hluavtaws tshaj cov roj hmab ntuj tau nce sai heev nyob rau yav dhau los tsis ntev los no. Muaj ntau hom roj hmab hluavtaws thiab lawv tau muab faib ua ob pawg, uas yog; general-purpose synthetic rubbers thiab tshwj xeeb lub hom phiaj roj hmab. General-purpose rubbers muaj ntau dua thiab siv dav hauv ntau cov txheej txheem tsim khoom. Neoprene thiab nitrile roj hmab yog ob hom kev siv dav dav siv roj hmab. Qhov sib txawv tseem ceeb ntawm neoprene thiab nitrile roj hmab yog neoprene yog tsim los ntawm emulsion polymerization ntawm chloroprene (2-chloro-1, 3-butadiene), hos nitrile roj hmab yog tsim los ntawm emulsion polymerization ntawm copolymer ntawm butadiene thiab acrylonitrile.
Neoprene yog dab tsi?
Neoprene yog lub npe lag luam rau chloroprene roj hmab lossis polychloroprene (CPR). Cov roj hmab chlorinated no yog thawj zaug tsim cov roj hmab hauv xyoo 1930s, tshwj xeeb tshaj yog rau kev siv roj. Nws yog tsim los ntawm emulsion polymerization ntawm chloroprene monomer thiab yog vulcanized siv magnesium oxide los yog zinc oxide vim sulfur vulcanization qeeb heev. Neoprene muaj oxidative degradation zoo heev vim muaj cov tshuaj chlorine atom hauv cov saw hlau polymer. Ntxiv mus, cov roj hmab no qhia tau hais tias cov tshuaj tiv thaiv zoo rau kev laus, tawm tsam los ntawm ozone, thiab UV irradiation. Neoprene nthuav tawm cov khoom tensile thiab hardness zoo; Yog li, nws yog qhov ua tau rau kev puas tsuaj los ntawm kev sib tw, flexing, thiab siab toughness. Neoprene tseem paub txog nws cov nplaim hluav taws zoo. Txawm li cas los xij, nws cov khoom hluav taws xob tsawg dua thaum piv rau cov roj hmab ntuj. Cov txheej txheem tshwj xeeb no tau coj cov roj hmab neoprene rau nws ntau yam kev siv, thiab hloov cov roj hmab ntuj hauv ntau qhov chaw. Txawm hais tias nws tau pib tsim rau nws cov roj tsis kam, nws qhia tau tias tsis muaj roj tsis kam thaum piv rau nitrile roj hmab. Cov log tsheb ua los ntawm neoprene qhia cov khoom zoo heev tab sis kim.
Daim duab 01: Neoprene
Neoprene yog dav siv los tsim cov hlau thiab cable tsho, raj, hose, thiab npog. Nws kuj tseem siv rau hauv kev lag luam tsheb los tsim cov ntsaws ruaj ruaj, khau khiab, gaskets, siv, molded, thiab extruded khoom. Ntxiv mus, neoprene raws li sealants thiab adhesives kuj muaj nyob rau hauv kev ua lag luam. Tsis tas li ntawd, neoprene yog siv nyob rau hauv latex dipped khoom thiab ntawv industries. Hauv kev lag luam hauv kev lag luam, cov khoom lag luam zoo li cov ntaub thaiv choj, cov av yeeb nkab gaskets, cov ntaub ntawv tsis muaj dej, cov khoom hloov kho asph alt yog tsim los ntawm cov roj hmab neoprene.
Nitrile Rubber yog dab tsi?
Nitrile roj hmab tseem hu ua acrylonitrile-butadiene roj hmab (NRB). Raws li lub npe implies, nitrile roj hmab yog ib tug copolymer ntawm acrylonitrile thiab butadiene thiab ua nyob rau hauv sib txawv piv ntawm 25:75 mus rau 75:25. Tsis zoo li tag nrho lwm cov khoom siv hluavtaws, cov roj hmab nitrile muaj cov roj zoo heev thiab hnyav hnyav. Txawm li cas los xij, nws tsis yog feem ntau siv hauv kev lag luam log tsheb vim nws cov nqi siab. Cov roj kuj tuaj yeem txhim kho los ntawm kev nce nws cov ntsiab lus acrylonitrile. Nitrile tsis qhia cov tshuaj tiv thaiv muaj zog tiv thaiv cov kua qaub. Nws yog haum rau UV irradiation thiab ozone.
Daim duab 02: Nitrile Rubber
Nitrile roj hmab yog siv rau kev tsim cov roj twj diaphragm, roj tso tsheb hlau luam, roj hoses, roj foob, gaskets, roj resistant khau, seals, thiab lwm yam.

Summary – Neoprene vs Nitrile Rubber
Neoprene yog chlorinated roj hmab tsim los ntawm emulsion polymerization ntawm chloroprene. Nws muaj UV thiab ozone tsis kam, nplaim hluav taws zoo, roj zoo thiab hnyav ua haujlwm, thiab zoo tensile thiab harness zog. Nitrile roj hmab yog ib tug copolymer ntawm butadiene thiab acrylonitrile thiab muaj cov roj zoo heev thiab hnyav, tab sis tsis muaj UV thiab ozone kuj. Qhov no yog qhov txawv ntawm neoprene thiab nitrile roj hmab.
