chloroprene rabha CR244
Neoprene, inozivikanwawo se chloroprene rubber uye Xinping rubber. Synthetic rubber inogadzirwa ne α-polymerization ye chloroprene (2- chloro -1,3- butadiene) inoshandiswa zvakanyanya mukugadzirwa kwemamiriro ekunze, maviscose soles, coatings uye rocket fuels.
Iyo flake kana block ine mukaka chena, beige kana yakapfava kutaridzika kwebrown is elastomer inogadzirwa nealpha polymerization ye chloroprene (kureva 2- chloro -1,3- butadiene) sechinhu chikuru mbishi. Iyo solubility parameter ye chloroprene rubber accounts ye δ = 9.2 ~ 9.41. Soluble mu toluene, xylene, dichloroethane uye vanadium ethylene, inonyungudika zvishoma muacetone, methyl ethyl ketone, ethyl acetate uye cyclohexane, isinganyunguriki mu n-hexane uye peturu inonyungudutsa, asi inonyungudika musanganiswa yakasanganiswa inoumbwa nezvakanaka zvinonyungudutsa uye zvakashata zvinonyungudutsa uye zvisinganyunguduki. kana kunyungudika kwakashata uye kusina kunyunguduka muchikamu chakakodzera, kuzvimba mumafuta emiriwo nemafuta emaminerari asi kwete kupera.
Zvakanaka zvemuviri uye zvemagetsi zvimiro, kuramba kwemafuta, kupisa kupisa, kuramba kwemurazvo, kushomeka kwezuva, ozone kuramba, asidhi uye alkali kuramba uye kemikari reagent kuramba. Zvakaipa kutadza kutonhora uye kugadzikana kwekuchengetedza. Iyo ine yakakwira tensile simba, elongation, reversible crystallinity uye yakanaka adhesion. Kuramba kuchembera uye kusagadzikana kwekupisa. Yakanakisa mafuta kuramba uye makemikari corrosion resistance. Kuramba kwemamiriro ekunze uye ozone kuchembera kuramba ndeyechipiri kune ethylene propylene rabha uye butyl rabha. Kupisa kupisa kwakaenzana neiyo nitrile rubber, ine tembiricha yekuora ye230 ~ 260 ℃, kushomeka kwe120 ~ 150 ℃, kushandiswa kwenguva refu pa80 ~ 100 ℃, uye kumwe kunonoka kwemurazvo. Oiri kuramba ndeyechipiri chete kune nitrile rubber. Good corrosion resistance kune inorganic acid uye alkali. Kusagadzikana kutonhora uye kusasimba kwemagetsi. Kugadzikana kwekuchengetedza kwerabha yakasvibiswa kwakashata, izvo zvinotungamirira kune chiitiko che "self-sulfur". Iyo Mooney viscosity inowedzera uye rabha yakasvibirira inoomesa. Mhando dzekunze dzinosanganisira AD-30 (USA), A-90 (Japan), 320 (Germany) uye MA40S (France).
CR122 chloroprene rabha: Zvigadzirwa zverabha zvakaita semabhandi ekutakurisa, mabhandi ekufambisa, waya netambo, mashizha erabha asingadzivirirwe nemafuta, hosi dzerabha dzisingachinji mafuta uye zvekuvharisa.

CR232 chloroprene rabha: tambo sheath, mafuta-inodzivirira rabha hose, chisimbiso cherabha, chinonamira, nezvimwe.
CR2441 2442 chloroprene rubber: mbishi yekugadzira inonamira, inoshandiswa kubatanidza simbi, huni, rabha, dehwe uye zvimwe zvinhu.
CR321 322 mhando chloroprene rubber: tambo, rabha bhodhi, yakajairika uye inodzivirira mafuta-inodzivirira rubber hose, mafuta-inodzivirira rabha bhutsu, mhepo deflector, poncho, tende jira, conveyor bhandi, conveyor bhandi, rabha chisimbiso, mweya cushion yekurima capsule, lifeboat, etc. Inoshandiswa seanoomesa mumiriri weakagadziridzwa acrylate nekukurumidza structural adhesive (SGA).
