Raba ya neoprene, leyi tivekaka tani hi polychloroprene, i rhaba yo endliwa hi tindlela to hambana hambana leyi kumeke ku tirhisiwa lokukulu eka tiindasitiri to hambana hambana. Swilo swa yona swo hlawuleka, swo tanihi ku lwisana ni oyili, ku hisa ni ku onhaka ka maxelo, swi endla leswaku yi va nchumu lowu rhandzekaka eka swilo leswi tirhisiwaka ku sukela eka swisirhelelo swa timovha ku ya eka ti- gasket ta le tifemeni. Xihloko lexi xi nghenelela eka swivumbeko swa rhaba ya neoprene, yi kambisisa xivumbeko xa yona xa tikhemikhali, swihlawulekisi swa michini na matirhiselo yo hambana hambana. Ku kuma ku twisisa loku dzikeke ka matirhiselo ya yona, u nga kambisisa Raba ya Neoprene . Nxopaxopo lowu wu kongomisa ku nyika nkatsakanyo lowu heleleke wa vuswikoti bya rhaba ya neoprene na swipimelo, ku pfuna tiindasitiri ku teka swiboho leswi nga na vutivi mayelana na matirhiselo ya yona.
Xivumbeko xa Tikhemikhali na Xivumbeko
Endlelo ra ku endla polymerization
Raba ya neoprene yi endliwa hiku tirhisa polymerization ya chloroprene (2-chlorobutadiene). Endlelo leri ri katsa emulsion polymerization, laha ti monomers ti hangalasiweke ematini hiku pfuniwa hi ti surfactants. Ti polymer chains leti humelelaka ti kombisa nkatsakanyo wo hlawuleka wa matimba na ku olova, leswi endlaka leswaku neoprene yiva nchumu lowu tiyeke swinene. Kuva kona ka chlorine eka xivumbeko xa yona swiendla leswaku yikota ku lwisana na oxidation naku onhaka, leswinga vuyelo bya nkoka eka rhaba ya ntumbuluko.
Ku Hlanganisa Swihambano na Vulcanization
Swihlawulekisi swa rhaba ya neoprene swinga antswisiwa kuya emahlweni hiku tirhisa cross-linking na vulcanization. Vulcanization yikatsa ku engeteriwa ka sulphur kumbe swin’wana leswi hlanganisaka ku endla network ya swiphemu swinharhu ya ti polymer chains. Endlelo leri ri antswisa swinene matimba ya michini ya nchumu lowu, ku olova ni ku tiya ka mahiselo. Kuya hi xitirhisiwa, degree ya cross-linking yinga lulamisiwa kuva ku fikeleriwa ku ringanisela loku lavekaka ka ku olova na ku tiya.
Swihlawulekisi swa Michini
Matimba ya Tensile na Elasticity
Raba ya neoprene yikombisa matimba ya kahle swinene ya tensile, hi ntolovelo kusuka eka 7 kuya eka 24 MPa, kuya hi xivumbeko na degree ya vulcanization. Elasticity ya yona yi pfumelela ku ololoka kuya fika eka 500% wa ku leha ka yona kosungula handle ka deformation ya nkarhi hinkwawo. Swihlawulekisi leswi swiendla leswaku yifaneleka eka switirhisiwa leswi lavaka matirhelo yale henhla ya michini, kufana na conveyor belts na swiphemu swa timovha.
Ku Tiyisela Ku Abrasion na Ku Tear
Xin’wana xa swilo leswi xiyekaka swa rhaba ya neoprene i ku tsandzeka ka yona ku rhurhumela ni ku handzuka. Leswi swiendla leswaku yiva kahle swinene kuva yitirhisiwa eka tindzhawu to tika laha ku onhaka ka michini switolovelekeke. Hi xikombiso, neoprene yi tala ku tirhisiwa eka tihoyisi ta le tifemeni ni le ka switirhisiwa swo sirhelela, laha ku tiya ku nga nchumu wa nkoka swinene.
Ku Lwisana ni ku Hisisa ni Tikhemikhali
Ku Tiyisela Ku Hisa
Raba ya neoprene yikota ku tiyisela mahiselo kusuka eka -40°C kuya eka 120°C, leswi endlaka leswaku yifaneleka eka switirhisiwa swa mahiselo yale hansi na mahiselo yale henhla. Ku tiya ka yona ka mahiselo switlhela swi antswisiwa hiku engeteriwa ka swiengeteri leswinga tiyiselaka kuhisa hinkarhi wa maendlelo ya compounding.
Ku Fambisana ka Tikhemikhali
Ku tiya ka tikhemikhali ta rhaba ya neoprene i yin’wana ya swihlawulekisi swa yona swa nkoka swinene. Yi kondzelela mafurha, mafurha ni tikhemikhali to tala, ku katsa ni ti- acid ni ti- alkali. Nhundzu leyi yi endla leswaku yiva nchumu lowu tsakeriwaka ngopfu eka ti seals, ti gaskets, na ti hoses eka ti indasitiri to lulamisa ti khemikhali.
Ku tirhisiwa ka Raba ya Neoprene
Vumaki bya Mimovha
Eka xiyenge xa timovha, rhaba ya neoprene yi tirhisiwa ngopfu ku endla swisirhelelo, tigasket ni tihoyisi. Ku tiya ka yona eka oyili na kuhisa switiyisisa leswaku yitshama nkarhi woleha eka swiyenge swa njhini na tindzhawu tin’wana leti lavaka matimba.
Vumaki na Switirhisiwa swa le Matini
Ku tiya ka maxelo ya Neoprene swiendla leswaku yiva nhlawulo wa kahle swinene eka switirhisiwa swo aka, kufana na ti bridge bearings na ti expansion joints. Vuswikoti bya yona byo tiyisela miseve ya UV na ozone byi tiyisisa ku tiya eka swiyimo swa le handle.
Switirhisiwa swa le ka tiindasitiri
Eka tindzhawu ta ti indasitiri, rhaba ya neoprene yitirhisiwa eka mabandhi yo fambisa, swiambalo swo sirhelela na ti pads to hunguta ku rhurhumela. Ku cinca cinca ka yona xikan’we naku tiya swiendla leswaku yiva nchumu lowu yaka eka switirhisiwa swohambana hambana swa ti indasitiri.
Swipimelo na Mintlhontlho
Swibumabumelo swa Ndleko
Hambileswi rhaba ya neoprene yi nyikelaka swipfuno swo tala, ntsengo wa yona wu nga va xivangelo lexi sivelaka eka switirhisiwa swin’wana. Endlelo ra vuhumelerisi xikan’we naku durha ka raw material swi hoxa xandla eka nxavo wa yona wale henhla loko ku pimanyisiwa na ti rhaba tin’wana ta synthetic.
Vuyelo bya Ntivo-mbango
Ku endliwa na ku lahliwa ka rhaba ya neoprene swi tisa mintlhontlho eka mbango. Matshalatshala ya endliwa ku tumbuluxa tindlela ta vuhumelerisi leti nga ta tshama nkarhi wo leha na tithekiniki to vuyisa swilo ku hunguta ku humelela ka yona eka mbango.
Mahetelelo
Raba ya neoprene i nchumu lowu tirhisiwaka hi tindlela to hambana hambana, hikwalaho ka ku hlanganisiwa ka wona ko hlawuleka ka swivumbeko swa michini, ku hisa na tikhemikhali. Ku sukela eka swisirhelelo swa timovha ku ya eka tigaskete ta tiindasitiri, ku pfuna ka yona a ku ringanisiwi na nchumu eka tiindasitiri to tala. Hambiswiritano, ku tekeriwa enhlokweni ko fana na ntsengo na ku khumbeka ka mbango swi fanele ku langutisiwa ku tiyisisa ku tirhisiwa ka yona loku nga heriki. Ku kuma ku lavisisa kun’wana ka matirhiselo ya yona na swivumbeko swa yona, endzela Raba ya Neoprene.
