Ibyinshi mubyo reberi ya v-umukandara usanzwe mubihugu byamahanga ni sbr / umubiri wa reberi karemano hamwe na chloropre. Umukandara woherejwe ni ugukoresha ibicuruzwa bya rubber, formula igomba kuzirikana imikorere ya dinamike, ibisekuru byubushyuhe nabyo, bigomba gufatwa nkibintu byabitangaza bibujijwe, ibishishwa ntibigomba gucika intege. Umukandara wo mu rwego rwo hejuru nk'umukandara ufunganye V-umukandara, v-umukandara wagabanijwe, umukandara w'inyungu ukoreshwa cyane muri chloroprepé. Imirongo ya Chloroprepre ifite imbaraga nyinshi, kurwanya ubushyuhe, kurwanya ubushyuhe, kurwanya ozone, ibitero bya atrosion, umunaniro mwiza cyane, kandi ufite agaciro keza nibindi bikoresho. Ubushyuhe bwakurikiyeho muri rusange-30 ~ 100 ℃. Umukandara mwinshi woherezamo amahanga ukoresha kristu yoroheje-intego ya Chloroprepre reberi. Ibikurikira nibipimo byimikorere yicyiciro cyinshi cya neoprene ikoreshwa muri ubu bushakashatsi
CR232: Iki gicuruzwa ni chloropree polymer hamwe na diisopropyl dithiocarbonate nka redulator. Umuvuduko wa kirisiti ni ugereranya, ubucucike ni 1.23, beige ibibyimba, bidahumanya. Ifite ubushyuhe bwiza nubushyuhe bwo hejuru. Irashobora gukoreshwa muburyo bwose bwibicuruzwa byamabara yumucyo, nka kashe, igifuniko cyumukungugu, umuzingo, umurongo, umugozi wo hanze hamwe nibindi bice binyuranye. Ibicuruzwa bisa na D-Ubwoko bwa M-40-40-Ubwoko bwa Chloropreprepre.
CR322: Iki gicuruzwa ni chloroprefe polymer hamwe na sufuru na diisopropyl dithiocarbonate nkivanga no guhindura umukozi. Umuvuduko ukabije wa Crystallisation, ubucucike 1.23, beige cyangwa ibibyimba byijimye, bidahumanya. Imbaraga ndende, imikorere yo gutunganya iruta reberi ishingiye kuri sulfure. Irashobora gukoreshwa mugikorwa cya kabili sheaths, imikandari ya convestior hamwe nibindi bicuruzwa bya rubber. Ibicuruzwa bisa na dupont gw ubwoko bwa reberi.
2.1 Ingaruka z'amanota itandukanye hamwe na dosage ya cr kuri cluscalisation imikorere na siney vitcosity ya v-umukandara wo gutunganya reberi.
Hamwe no kongera dosiye igihe kirekire. Na m hm ntabwo mpinduka byinshi. Byongeye kandi, nkuko ingano ya CR3222 yiyongera, T 10 na T 90 ni ngufi. Ibi biterwa nuko cr3222 ni ubwoko buvanze kandi bwahinduwe, Zno, Mgo na CYIZA BIKURIKIRA MU GIHE CYIZA NA NR / BR, M HM L yiyongereye buhoro buhoro. Hanyuma, muri sisitemu yo kumvikana ubu, CR3222 ifite igihe gito cyo gutwika, igipimo cya Gukangura vuba hamwe nurwego rwo hejuru rwo gutera inkunga kuruta cr2322.
Uruzisi rwa Mooney rwiyongereye cyane hamwe no kongera CR. CR2322 yiyongera kurenza CR3222 hamwe na CR dosage, ariko cr3222 nini mugihe umubare umwe wa CR ukoreshwa.
2.2 Ingaruka zamanota atandukanye hamwe nigipimo cyimbwa yumubiri nubukanishi bya V-umukandara
Hamwe no kwiyongera kwa CR2322, muri rusange guhindura imbaraga za kanseri ntabwo bifite akamaro, kurambura kugabanuka kugabanuka, guhangayika 100% no gukomera. No kuri 100 ℃ hamwe nigihe cyo gusaza igihe, imbaraga zidake cyane, urwanira umwanya wagabanutseho hamwe na cr2322, imbaraga zidake cyane, zinganira kure zagabanutse kugabanuka gake; Hamwe nigihe cyo kongera imyaka 100% buri gihe, gukomera kwiyongereye, hamwe nigipimo gitandukanye cya CR2322, guhora gihora cyo hejuru, gukomera kwa kabiri byiyongereyeho margin, ariko ni nto kuruta formula idafite cr2322.
Hamwe no kwiyongera kwa CR3222 Iyo tutageze mu za bukuru, imbaraga za kanseri ntizigeze zihinduka, guhangayikishwa na kanseri 100% bahoraga rwagabanutseho nyuma kandi koko icyaha nticyahindutse cyane. Na 100 ℃ ibidukikije hamwe nigihe cyo gusaza igihe, imbaraga zidake cyane zagabanutse hamwe nigipimo gitandukanye cyimbaraga za cr3222 zagabanutseho umubare muto, ariko uri nto kuruta formulaire idafite cr3222; Hamwe nigihe cyo kwiyongera kwa 100% bikabije, gukomera biriyongera, hamwe nigipimo gitandukanye cya CR3222 cya 100% ya kanseri yatunganijwe 100%, ubukana ntibiriyongera cyane. Munsi yigihe gito cyo gusaza CR kuri 100 ℃, igipimo cyimpinduka zimbaraga za cr3222 ni ntoya kurenza iyi cr2322 hamwe nigihe cyo gusaza; Igipimo cyo guhindura umwanya wo kurahira, kurahira 100%, no ku nkombe gukomera cr3222 na cr2322 ntabwo bitandukanye cyane nibya CR2322.
Muri sisitemu yo guswera, umutungo wa CR2322 ni mwiza cyane kurenza uko CR3222 kuri 80 ℃, hamwe nibyiyongera kuri cr2322, hamwe numutungo wa CR2322, hamwe numutungo wa CR222
2.3 mullins ingaruka zamanota atandukanye no gukora cr kumurongo wa V-umukandara
Kubera ko reberi ya compression ikorerwa imihangayiko isubiramo mugihe gikoreshwa bisanzwe, kandi imihangayiko yoroshye igomba kuba ntoya ikeneye imihangayiko ya refression, bityo ibigo bya mullic bikaba bimaze gukomera ku nkombe za Concess. Ubushyuhe busanzwe bwa v-umukandara usanzwe ni hafi 80 ℃, kugirango tuyigana imikoreshereze isanzwe yo gutuza, ingaruka mbi kuri 80 ℃ zageragejwe kugirango zigaragaze imikoreshereze nyayo ya Leta.
Hamwe no kongera umubare wa cr2322, imbaraga ntarengwa zo kwiyongera ziyongera mbere na nyuma ya 100 ℃ × 24h ishaje. Iyo umubare wa CR2322 wakoreshejwe ni kimwe, imbaraga ntarengwa zo kwiyongera kwiyongera nyuma ya 100 ℃ × 24 H gusa. Kubera ko itandukaniro rito riri hagati y'ingabo za mbere n'icya za gatatu zigaragaza ko ingaruka za Mullins ziracyafite intege nke mubwiyongere bwimibare ya CR2322 nyuma yo kwiyongera kwa 100 ℃ × 24 h. Ariko, ugereranije nibyo mbere yo gusaza, agaciro ntarengwa copression imbaraga ziyongera mbere na nyuma yo gusaza. Ariko, ugereranije nibyo mbere yo gusaza, urwego rwimikorere ya Mullins rwiyongereye nyuma ya 100 ℃ × 24 H gusa, kandi urugero rwangiza ingaruka za CR2322.
CR3222 ifite urugero nk'urwo hamwe na cr2322 mubijyanye na mullins ingaruka. Kugereranya cyane hagati ya CR3222 na CR2322 byerekana ko ukurikije imbaraga ntarengwa, cr3222 nini cyane kuruta cr2322 kuri cr dos, kandi niko nyuma yo gusaza kuri 100 ℃ × 24 h. Kubijyanye na mullins ingaruka, itandukaniro ryingaruka za mullins hagati ya cr3222 na cr2322 kuri cr imwe mbere yo gusaza hagati ya cr2322 na cr322 saa 100 ℃ × 24 h ntabwo ari byiza. Ariko, nyuma yo gusaza kuri 100 ℃ × 24 h, Ingaruka ya Mullins ya CR3222 ifite intege nke kurenza uko CR2322 kuri cr dosage.
2.4 Ingaruka Zitsinda ritandukanye nimbeho
Ikintu cyo Gutakaza (Tanδ), kikaba tangent yicyiciro cyicyiciro kiri hagati yumurima wibikoresho byo guhosha byingufu mubintu byubushyuhe bwingufu. Kubwibyo, ingaruka zamanota atandukanye hamwe nijwi rya cr kuri tanδ ya V-Tralt Compressions reberi zakozweho iperereza.
Hejuru yubushyuhe bwikizamini, hepfo ya tangire ya reberi ya gilcani gusa, kandi hejuru ya regine ya reberi yakuweho hamwe no gukoresha cr, ibi bifitanye isano nukuri
Ibi bifitanye isano na cl kuruhande rwimiterere ya molecular ya cr. Igicapo cya rubber yahujwe igabanuka hamwe no kongera umubare wa cr2322, ariko itandukaniro ntabwo rigaragara mugihe ubushyuhe buri munsi ya 100 ℃. Byongeye kandi, Tagitani ya reberi ya gilcani igabanuka hamwe no kongera umubare wa cr3222, ariko itandukaniro ntabwo rigaragara munsi ya 100 ° C. Byongeye kandi, tanδ ya reberi ya gilcani gusa ni ntoya mu bice 20 bya CR3222. Mubigereranya birebire, tanδ ya cr3222 iri munsi yicya cr2322 ku bushyuhe bumwe na cr imwe nini ku buryo bukenewe mu kuboko ku buryo bwo gukiza.
Umwanzuro
. Hamwe no kwiyongera kwa CR3222, T 10 na T 90 byagabanijwe kandi m HM byiyongereye buhoro buhoro. Uruzinduko rw'ibintu byiza byiyongera cyane hamwe no kwiyongera kwa CR Dosage, na CR2322 ni binini kuruta cr3222 mubijyanye no kongera amplitude, ariko agaciro ka cr3222 ni kinini mugihe umubare umwe wa cr ukoreshwa.
. Hamwe no kongera cr3222, imbaraga za tensile ntizihinduka cyane, kwihitiramo kurira bigabanuka, guhangayikishwa 100% 100% bigabanuka, kandi byiyongera, kandi gukomera ntabwo bihinduka byinshi. Umubare w'ibipimo by'imiterere yumubiri na mashini ya CRS byiyongereye nyuma yo gusaza saa 100 ℃ × 24 h. Sisitemu yo kudusagura iriho nayo yasanze ifite umubare wo kongeraguka imitungo yumubiri na mashini. Muri sisitemu yo kurongora ubu, kurwanya flixire ya cr2322 nibyiza cyane kurenza uko CR3222 kuri 80 ℃.
. Kubijyanye n'imbaraga nyinshi, CR3222 biragaragara kuruta cr2322 kuri CR2322 kuri sasita, kandi ni kimwe nyuma yo gusaza kuri 100 ℃ × 24 h. Kubijyanye na mullins ingaruka, mbere yo gusaza kuri 100 ℃ × 24 h, nta tandukaniro ryinshi hagati ya CR3222 na CR2322 mubijyanye na 100 ℃ × 24 h2322 na cr2322 bifite ibintu byiza cyane kuruta cr2322 kuri cr dosage. Ariko, nyuma yo gusaza kuri 100 ℃ × 24 h, Ingaruka ya Mullins ya CR3222 ifite intege nke kurenza uko CR2322 kuri cr dosage.
. Byongeye kandi, nkuko ingano ya cr3222 yiyongera, tagi tagi ya reberi ya gilcanize ni ntoya mugihe ingano ya cr3222 ari ibice 20. Tanδ ya CR3222 iri munsi yicya cr2322 ku bushyuhe bumwe na cr imwe.
