1 Vulcanization matirhelo ya rhaba yo hambana ya ethylene propylene .
Vuyelo bya nhlayo ya ethylene eka nkarhi wo hisa (TC10) na process positivity ya rhaba ya ethylene propylene.
(vuyelo bya nhlayo ya ethylene eka nkarhi wo horisa wa rhaba ya ethylene propylene (TC10) na process vulcanization time (TC90) i tikulu, hi ku tlakuka ka ethylene, nhlayo ya TC10 na TC90 ya nchumu lowu yi pfuxetiwile hakatsongo Same, loko nhlayo ya monomer ya vunharhu yi ri ehansi, TC10 na TC90 ya nchumu lowu yi komile; Torque ya le hansi (ML) ya nchumu lowu, nhlayo ya le hansi ya monomer ya vunharhu.
The minimum torque (ML) of the material is mainly affected by the ethylene content, the higher the ethylene content, the greater the ML of the material, the worse the mobility at the beginning of vulcanization, because the maximum torque (MH) can reflect the modulus of the rubber, it can be seen that with the increase of ethylene content, the modulus of the rubber also increases gradually, the third monomer content on the modulus of the material is positively Ku ringana na ku hoxa xandla ka nhlayo ya vunharhu ya monomer i ku tlakuka ka nhlayo ya swilo leswi, loko modulus ya swilo leswi nga kona swi ri swikulu, modulus ya swilo leswi nga kona yi va yikulu, modulus ya swilo leswi nga kona yi va yikulu. Eka nhlayo ya ethylene leyi fanaka kumbe leyi fanaka, loko nhlayo ya vunharhu ya monomer yiri e henhla, modulus yale henhla. Ku hambana exikarhi ka torque yale henhla swinene na torque yale hansi (MH -ml) switirhisiwa ku hlamusela cross-linking degree ya nchumu wa rhaba, naswona swinga voniwa leswaku nhlayo ya ethylene xikan’we na nhlayo ya vunharhu ya monomer swina mbuyelo lowu fanaka eka cross-linking degree, ethylene yale henhla ya cross-linking degree yiva yikulu swinene, naswona nhlayo yale henhla ya monomer ya vunharhu, the cross-contering the cross-conted the degree the material is nayond is na yona degree.
2 Swihlawulekisi swa michini swa ndzavisiso wo hambana wa rhaba ya ethylene propylene .
Ku tiya ka rhaba swi khumbeka ngopfu hi nhlayo ya ethylene, loko nhlayo ya ethylene yiri e henhla, ku tiya ka rhaba yale henhla, nhlayo ya vunharhu ya monomer yina mbuyelo wutsongo eka ku tiya; material tensile strength and tear strength by ethylene is more obvious, with the increase of ethylene content, the material tensile strength and tear strength are gradually increased, when the ethylene content is similar or the same, the higher the third monomer content, the higher the material tensile strength and tear strength, indicating that ethylene content is the same, the higher the material tensile strength, the higher the material tensile strength, the higher the material tensile strength, the higher the material Matimba ya tensile, matimba ya material tensile, material tensile strength na matimba yo handzuka swiva swiri e henhla. Hilaha ku fanaka, loko nhlayo ya vunharhu ya monomer yi ri ehenhla, matimba ya tensile ya le henhla na matimba yo handzula ya swilo leswi, leswi kombisaka leswaku nhlayo ya ethylene na nhlayo ya vunharhu ya monomer eka matimba ya mbuyelo wa mbuyelo wa synergistic; Nhlayo ya ethylene na nhlayo ya vunharhu ya monomer ya ntshikelelo wa ku ololoka ka swilo swi fana na ku khumbeka eka matimba ya swilo leswi, loko nhlayo ya ethylene yi ri ehenhla, loko nhlayo ya vunharhu ya monomer yi ri ehenhla eka ntshikelelo wa ku tsana ka swilo hi ku fambisana loko yi ri yikulu; Ethylene content ya tensile elongation ya mbuyelo lowuntsongo, endzeni ka range yokarhi ya tensile elongation ya material hiku tlakuka ka ethylene content, kuya eka point yokarhi, tensile strength na tear strength ya material swiya swikula, kuya eka point yokarhi, nhlayo ya vunharhu ya monomer ya vunharhu. Endzeni ka ndzhawu yokarhi, ku leha eka ku wisa ku tlakuka hakatsongotsongo hiku tlakuka ka nhlayo leyi simekiweke eka ethylene, kutani ku sungula kuhunguteka hakatsongotsongo endzhaku ka degree yokarhi, nhlayo ya vunharhu ya monomer yiringanela hindlela yohambana eka ku cinca ka ku leha eka ku wisa, eka nhlayo leyi fanaka kumbe leyi fanaka ya ethylene-based content, nhlayo ya monomer ya vunharhu yiva yikulu, ku tlakuka lokukulu eka ku wisa ka nchumu lowu kuri kona; Matirhelo ya abrasion ya swilo leswi yana vuxaka lebyikulu na ku tiya ka wona na matimba, hiku angarhela, loko ku tiya na matimba swiri e henhla, volume ya abrasion yitava yitsongo hiku landza sweswo, naswona matirhelo ya abrasion yata antswa; Loko nhlayo ya ethylene yi ya yi andza, ku na vuxaka byo karhi exikarhi ka ku tiya na matimba na matirhelo ya abrasion ya swilo leswi. Ku tiya ka swilo na matimba swina mpimo wokarhi wa ku tlakuka, volume ya abrasive yihunguteke hakatsongotsongo, matlhelo mambirhi ya nhlayo ya vunharhu ya monomer yata tlhela ya khumba swivumbeko swa abrasive swa material, leswi vonakaka eka ku tlakuka ka nhlayo ya vunharhu ya monomer, swita hunguta volume ya abrasive ya swilo, kambe loko swipimanyisiwa na mbuyelo wa ethylene content, nhlayo ya vunharhu ya monomer yina nkucetelo eka swivumbeko swa yona swa abrasive.
3 Ku hambana ka Ethylene Propylene rhaba ya matirhelo ya ku dyuhala ka moya lama nga hisiki .
Swinga voniwa leswaku, endzhaku ka ku dyuhala eka 160 °C kuringana 24h, ku tiya ka swilo swi cinca swintsongo swinene, ntshikelelo wa tensile lowu tshamaka wuri kona wu tlakuka nyana, kambe nhlayo hinkwayo ya ku khoma yile henhla, matimba ya tensile ya hunguteka nyana, mpimo wa ku khomiwa hinkwako wutshama wuri e henhla, naswona mpimo wa ku leha ka tensile wu antswisiwile nyana; Leswi swi vangiwa hikuva rhaba ya ethylene-propylene i rhaba leyi nga na saturated main chain, leyi nga na ku lwisana ka le henhla ka ku dyuhala ka moya-moya. Hikwalaho ka ku lwisana lokunene ka moya wo hisa ka rhaba ya ethylene propylene, swa tika ku kombisa mbuyelo wa nhlayo ya ethylene na nhlayo ya vunharhu ya monomer eka matirhelo ya ku dyuhala ya swilo eka nkarhi wo koma wa ku dyuhala ka moya wo hisa.
4 Ku hambana ka rhaba ya ethylene propylene ku lwisana na mahiselo ya le hansi .
Hiku tlakuka ka nhlayo ya ethylene, ku tiya ka mahiselo yale hansi ya swilo leswi swiya swi hohloka hakatsongotsongo.
Hi ku tlakuka ka nhlayo ya ethylene, ku lwisana ka mahiselo ya le hansi ka nchumu lowu swi hohloka hakatsongo-tsongo, nhlayo ya ethylene leyi fanaka kumbe leyi fanaka, loko nhlayo ya monomer ya vunharhu yi ri ehansi, ku lwisana ka mahiselo ya le hansi ku antswa ka swilo leswi, leswi swi vangiwa hileswi nhlayo ya ethylene ya ethylene propylene yi engeteleka Ku tlakuka ka vuswikoti bya crystallization swita yisa eka ku tlakuka ka ku tiya na matimba ya swilo, kambe switlhela swihunguta ku olova ka molecular chain hinkwayo, leswaku ku lwisana ka mahiselo yale hansi ya nchumu lowu ku hohloka. Loko nhlayo ya ntlawa wa ethylene yiri ekusuhi na yin’wana, nhlayo yale hansi ya monomer ya vunharhu yita yisa eka degree yale hansi ya cross-linking ya material, leswinga ta engetela ku olova ka molecule hinkwayo, naku antswisa ku tiya ka mahiselo yale hansi ya swilo.
