Neoprene rubber, leyi tlhelaka yi tiviwa tani hi polychloroprene, i rubber yo endliwa hi tindlela to hambana hambana leyi kumeke ku tirhisiwa loku hangalakeke eka ti indasitiri to hambana hambana. Swilo swa yona swo hlawuleka, swo tanihi ku lwisana ni oyili, ku hisa ni maxelo, swi endla leswaku yi va nchumu lowu tsakeriwaka eka switirhisiwa swo hambana-hambana ku sukela eka swisirhelelo swa timovha ku ya eka tigasiti ta le tifemeni. Xihloko lexi xi nghenelela eka swivumbeko swa rhaba ya neoprene, ku lavisisa xivumbeko xa yona xa tikhemikhali, swihlawulekisi swa michini, na switirhisiwa swo hambana. Ku kuma ku twisisa loku dzikeke ka switirhisiwa swa yona, u nga kambisisa . rhaba ya neoprene . Nxopaxopo lowu wu kongomisa ku nyika nkatsakanyo lowu heleleke wa vuswikoti bya Neoprene Rubber na swipimelo, ku pfuna tiindasitiri ku teka swiboho leswi nga na vutivi mayelana na matirhiselo ya yona.
Xivumbeko xa tikhemikhali na xivumbeko .
Endlelo ra polymerization .
Neoprene rubber yi endliwa hiku tirhisa polymerization ya chloroprene (2-chlorobutadiene). Endlelo leri ri katsa emulsion polymerization, laha ti monomers ti hangalasiwaka 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 kuva na ku lwisana ka yona na oxidation xikan’we naku onhaka, leswinga vuyelo bya nkoka eka rhaba ya ntumbuluko.
Ku hlanganisiwa ka swihambano na ku vulcanization .
Swihlawulekisi swa rhaba ya neoprene swinga antswisiwa swinene hiku tirhisa cross-linking na vulcanization. Vulcanization yi katsa ku engeteriwa ka sulphur kumbe swin’wana leswi hlanganisaka ku hlanganisa ku vumba netiweke ya swiphemu swinharhu ya tikhetane ta polymer. Endlelo leri ri antswisa swinene matimba ya michini ya nchumu lowu, ku olova, na ku tiya ka ku hisa. Kuya hi xitirhisiwa, degree ya cross-linking yinga lulamisiwa ku fikelela balance leyi lavekaka ya flexibility na rigidity.
Swivumbeko swa michini .
Matimba ya ku tsana na ku olova .
Neoprene rubber yikombisa matimba ya kahle swinene ya tensile, hi ntolovelo kusuka eka 7 kuya eka 24 MPa, kuya hi formulation na degree ya vulcanization. Ku olova ka yona swipfumelela 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 ti conveyor belts na swiphemu swa movha.
Ku rhurhumela ni ku lwisana ni mihloti .
Xin’wana xa swilo leswi xiyekaka swa rhaba ya neoprene i ku lwisana ka yona ni ku rhurhumela ni ku handzuka. Leswi swiendla leswaku yiva kahle swinene eka tindzhawu to tika laha ku onhaka ka michini na ku handzuka swi tolovelekeke. Hi xikombiso, neoprene yitala kutirhisiwa eka tihoyisi ta ti indasitiri na switirhisiwa swo sirhelela, laha ku tiya kunga nchumu wa nkoka swinene.
Ku lwisana na ku hisa na tikhemikhali .
Ku lwisana na ku hisa .
Neoprene rubber yinga tiyisela mahiselo lawa yanga kusuka eka -40°C kuya eka 120°C, leswi endlaka leswaku yifaneleka eka switirhisiwa swa mahiselo yale hansi xikan’we na mahiselo yale henhla. Ku tiya ka yona ka mahiselo switlhela swi antswisiwa hiku engeteriwa ka swiengeteri leswi lwisanaka na kuhisa hinkarhi wa maendlelo ya compounding.
Ku fambisana ka tikhemikhali .
Ku lwisana ka tikhemikhali ta rhaba ya neoprene i xin’wana xa swihlawulekisi swa yona swa nkoka swinene. Yi lwisana ni mafurha, mafurha ni tikhemikhali to tala, ku katsa ni ti- acid ni ti- alkali. Ndhawu leyi yi endla leswaku yi va nchumu lowu tsakeriwaka eka ti- seal, ti- gaskets ni tihoyisi eka tiindasitiri to lulamisa tikhemikhali.
Ku tirhisiwa ka rhaba ya neoprene .
Indasitiri ya Mimovha .
Eka xiyenge xa timovha, rhaba ya neoprene yi tirhisiwa ngopfu ku endla swisirhelelo, ti- gasket ni tihoyisi. Ku lwisana ka yona na oyili na kuhisa switiyisisa matirhelo ya nkarhi woleha eka swiyenge swa njhini na tindzhawu tin’wana leti lavaka.
Ku aka na switirhisiwa swa le makaya .
Ku lwisana ka maxelo ya Neoprene swi endla leswaku yi va nhlawulo wa kahle swinene eka switirhisiwa swa ku aka, ku fana na ti bearings ta buloho na swihlanganisi swo andzisa. Vuswikoti bya yona byo tiyisela UV radiation na ozone switiyisisa ku tiya eka swiyimo swale handle.
Switirhisiwa swa tiindasitiri .
Eka swiyimo swa le tifemeni, rhaba ya neoprene yi tirhisiwa eka mabandhi yo fambisa, swiambalo swo sirhelela ni tiphedi to hunguta ku rhurhumela. Ku cinca cinca ka yona xikan’we naku tiya ka yona swiendla leswaku yiva switirhisiwa swoya eka switirhisiwa swotala swa ti indasitiri.
Swipimelo na Mintlhontlho .
Ku tekeriwa enhlokweni ka ntsengo .
Hambi leswi neoprene rubber yinyikaka swipfuno swotala, ntsengo wa yona wunga va swipimelo eka switirhisiwa swin’wana. Endlelo ra vuhumelerisi na switirhisiwa swa raw material swi hoxa xandla eka nxavo wa yona wale henhla loko ku pimanyisiwa na ti rubber tin’wana ta synthetic.
Ku khumbeka ka mbango .
Ku endliwa na ku lahliwa ka rhaba ya neoprene swi tisa mintlhontlho ya mbango. Matshalatshala ya le ku endliweni ku tumbuluxa tindlela ta vuhumelerisi leti nga ta tshama nkarhi wo leha na tithekiniki to vuyisa swilo leswi nga tirhisiwangiki ku hunguta ku kandziyisiwa ka yona ka mbango.
Mahetelelo
Neoprene rubber i nchumu lowu tirhisiwaka hi tindlela to hambana hambana lowu nga na switirhisiwa swo hambana hambana, hikwalaho ka nkatsakanyo wa yona wo hlawuleka wa michini, ku hisa, na tikhemikhali. Ku suka eka swisirhelelo swa timovha ku ya eka ti- gasket ta le tifemeni, vukorhokeri bya yona a byi ringanisiwi na nchumu eka tiindasitiri to tala. Hambiswiritano, ku tekeriwa enhlokweni ko fana na ntsengo na ku khumbeka ka mbango swi fanele ku lulamisiwa ku tiyisisa ku tirhisiwa ka yona loku nga heriki. Ku ya emahlweni na ku lavisisa switirhisiwa swa yona na tindhawu ta yona, endzela . rhaba ya neoprene ..
