Uma ufana nami, uhlale ubheke izindlela zokuthuthukisa amakhono akho obuciko. Futhi enye yezindlela ezinhle kakhulu zokwenza lokho ukufunda ngezinto ezihlukene kanye nendlela yokuzisebenzisa. Ngakho-ke namuhla, ngifuna ukuqhathanisa izinto ezimbili ezithandwayo zokwakha: irabha ye-silicone ne-neoprene.
Isingeniso: yini irabha ye-silicone ne-neoprene?
Irabha ye-Silicone ne-neoprene yizinto ezimbili ezivame ukusetshenziswa ezinhlobonhlobo zezicelo. Zombili izinto ezisetshenziswayo zinezakhiwo zazo ezihlukile ezizenza zifanelekele izinhloso ezehlukene.
Irabha ye-Silicone iyirabha yokwenziwa eyenziwe nge-silicon, umoya-mpilo, nezinye izinhlanganisela eziphilayo. Irabha ye-Silicone inezinhlobonhlobo zezicelo ngenxa yokumelana kwayo nokushisa nokubanda, kanye nokuguquguquka kwayo nokuqina. Irabha ye-Silicone inezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa izimpawu nama-gaskets, ukufakwa kukagesi, kanye nemishini yezokwelapha.
I-Neoprene iyirabha yokwenziwa eyenziwe nge-chloroprene. Yasungulwa okokuqala ngeminyaka yawo-1930s futhi kusukela ngaleso sikhathi yasetshenziswa ezintweni ezahlukahlukene ezifana nama-wetsuits, ama-gaskets, nama-seal. I-Neoprene yaziwa ngokumelana kwayo okuhle kakhulu nowoyela namakhemikhali, kanye nezakhiwo zayo ezinhle zokuvikela.
Izakhiwo: qhathanisa izakhiwo ezibalulekile zento ngayinye
Omunye umehluko oyinhloko phakathi kwerabha ye-silicone ne-neoprene ukuthi irabha ye-silicone inebanga lokushisa eliphakeme kune-neoprene. I-Neoprene ingakwazi ukumelana namazinga okushisa afinyelela ku-200°F, kuyilapho irabha ye-silicone ikwazi ukumelana nezinga lokushisa elifinyelela ku-500°F. Ngaphezu kwalokho, irabha ye-silicone imelana kakhulu nokukhanya kwe-UV ne-ozone kune-neoprene.
I-Neoprene iyirabha yokwenziwa eyasungulwa ngawo-1930. Isetshenziswa ezinhlelweni ezahlukahlukene, kufaka phakathi ama-wetsuits, imikhono yelaptop, namaphedi egundane. I-Neoprene inezinga eliphezulu lokumelana namakhemikhali futhi ayinciphisi kalula. Iphinde imelane nokushisa nokubanda, okuyenza ibe yinto ekahle yezinhlelo eziningi zangaphandle.
Irabha ye-Silicone enye irabha yokwenziwa eyasungulwa ekuqaleni kwekhulu lama-20. Irabha ye-Silicone inezinhlobonhlobo zezicelo ngenxa yezakhiwo zayo eziyingqayizivele. Irabha ye-Silicone imelana namazinga okushisa aphakeme, ukukhanya kwe-UV, namakhemikhali. Iphinde ibe ne-coefficient ephansi yokungqubuzana, okuyenza ilungele ukusetshenziswa kuma-seal nama-gaskets.
Yiziphi izinzuzo zenjoloba ye-silicone?
Irabha ye-Silicone inezinto eziningi ezenza kube ukukhetha okuhle kakhulu kwezinhlelo zokusebenza ezihlukahlukene, okuhlanganisa ukumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukufakwa kukagesi, ukumelana namakhemikhali, nokumelana nesethi yokucindezela.
Enye yezinzuzo ezibalulekile zenjoloba ye-silicone ukumelana kwayo namazinga okushisa aphezulu. Ingasetshenziswa ezindaweni ezisukela ku -55°C kuya ku-+300°C (-67°F kuya ku-572°F), ikwenze kube ukukhetha okuhle kwezinhlelo zokusebenza ezihlukahlukene.
Irabha ye-Silicone futhi inokumelana okuhle kakhulu nokukhanya kwe-UV, i-ozone, nomoya-mpilo, okuyenza ilungele ukusetshenziswa ngaphandle. Iphinde imelane namakhemikhali, uwoyela, namafutha, okwenza kube ukukhetha okuhle lapho lezi zinto zikhona.
Irabha ye-silicone nayo iyimpahla enwebeka kakhulu, okusho ukuthi ingabuyela esimweni sayo sasekuqaleni ngisho nangemva kokunwetshwa noma ukucindezelwa. Lokhu kuyenza ilungele izinhlelo zokusebenza lapho kudingeka khona ukuguquguquka.
Okokugcina, irabha ye-silicone iyinto evumelana kakhulu nemvelo. Ayinabo ubuthi futhi ingaphinda igaywe kabusha, okwenza kube ukukhetha okuhle kwezinhlelo zokusebenza lapho ukucatshangelwa kwemvelo kubalulekile.
Yiziphi izinzuzo ze-neoprene?
I-Neoprene inezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa ukusetshenziswa njenge-padding kanye nokufakwa kwezimboni ezihlukahlukene zezimboni. Irabha ye-Neoprene ukumelana nokushisa, uwoyela, nokuhuzuka. Iphinde imelane nokuwohloka kokukhanya kwelanga kanye nesimo sezulu.
Kunezinzuzo eziningi zokusebenzisa i-neoprene, kufaka phakathi okulandelayo:
-Ayikwazi ukumelana namafutha, amakhemikhali nokushisa. Lokhu kukwenza kube yisinqumo esihle sokusebenzisa izinhlelo eziningi zezimboni.
-Inezici ezinhle zokuvikela i-insulating, okuyenza ibe wusizo ekukhuselweni nasekufakweni kwamanzi.
-Kuyaguquguquka futhi kukhululekile ukugqoka, okwenza kube ukukhetha okudumile kwezingubo ezifana nama-wetsuits.
-Akubizi kakhulu ukukhiqiza, okwenza kube inketho engabizi kakhulu ezinhlelweni eziningi.
I-silicone irabha ne-neoprene iqhathaniswa kanjani ngokwezindleko?
Ngokwezindleko, irabha ye-silicone ngokuvamile ibiza kakhulu kune-neoprene. Kodwa-ke, kunezici ezithile ezingathinta intengo, njengohlobo lwerabha ye-silicone kanye nenani olidingayo. Isibonelo, irabha ye-silicone yezinga lezokwelapha ingase ibize kakhulu kunerabha ye-silicone yenhloso evamile. Ngokwenani, ukuthenga ngobuningi kungase kunciphise izindleko zizonke ngeyunithi ngayinye.
Iyiphi engcono kunezinhlelo zokusebenza ezithile - irabha ye-silicone noma i-neoprene?
Lo mbuzo onzima ukuwuphendula njengoba uncike kuhlelo lokusebenza noma imfuneko ethile. Ngokuvamile, irabha ye-silicone inokumelana okungcono nokushisa okuphezulu kune-neoprene, okwenza kube yisinqumo sokuqala sezinhlelo zokusebenza lapho ukumelana nokushisa kubalulekile. Kodwa-ke, irabha ye-neoprene inokumelana kangcono nophethiloli namafutha kunerabha ye-silicone, ngakho-ke kungaba ukukhetha okuthandwayo ezinhlelweni lapho lezo zikhona. Mayelana nokumelana kwamakhemikhali, zombili izinto ezisetshenziswayo zifana kakhulu - zombili ziphikisana nama-acids amaningi nama-alkali, kodwa akufanele zisetshenziswe nama-solvents.
I-silicone irabha ne-neoprene iqhathaniswa kanjani nomthelela wemvelo?
Ngokuphathelene nomthelela wemvelo, irabha ye-silicone ne-neoprene ifana kakhulu. Zombili zenziwe ngezinto zokwenziwa, futhi zombili azinaboli. Kodwa-ke, irabha ye-silicone ngokuvamile ibhekwa njenge-eco-friendly kune-neoprene.
Umehluko owodwa omkhulu phakathi kwalokhu okubili ukuthi irabha ye-silicone yenziwe nge-silicon, into eyenzeka ngokwemvelo, kuyilapho i-neoprene yenziwe ngemikhiqizo ye-petroleum. Lokhu kwenza irabha ye-silicone ibe yinsiza evuselelekayo. Ukwengeza, irabha ye-silicone ingasetshenziswa kabusha, kuyilapho i-neoprene ingakwazi.
Irabha ye-Silicone nayo mancane amathuba okuthi ikhiphe amakhemikhali ayingozi emvelweni. I-Neoprene iqukethe ama-chlorofluorocarbon (CFCs), angalimaza ungqimba lwe-ozone, nama-polychlorinated biphenyls (PCBs), angabangela izinkinga zempilo kubantu nasezilwaneni. Irabha ye-Silicone ayinawo la makhemikhali ayingozi.
Sekukonke, irabha ye-silicone iyindlela evumelana ne-eco-friendly yezinto ezimbili.
Yikuphi okufanele ukhethe - irabha ye-silicone noma i-neoprene?
Impendulo yalo mbuzo incike ekutheni yiziphi izakhiwo oziqakathekisa kakhulu endabeni yenjoloba. Irabha ye-Silicone yaziwa ngokumelana nokushisa kwayo, kuyilapho i-neoprene yaziwa ngokumelana nowoyela.Nansi incazelo enemininingwane yezinto ezibalulekile zento ngayinye:
Irabha yeSilicone:
-Ukumelana nokushisa: Irabha ye-Silicone ingakwazi ukumelana namazinga okushisa afika ku-500 ° F. Njenge ukumelana nokushisa kwe-silicone strip yerabha.
-Ukumelana nesimo sezulu: Irabha ye-Silicone imelana nokubanda okukhulu nokushisa okukhulu. Iphinde imelane nemisebe ye-UV, i-ozone, nomswakama.
-Izakhiwo zikagesi: Irabha ye-Silicone inezindawo ezinhle zokuvala ugesi. Njenge ishidi legwebu le-silicone conductive kagesi.
-Ukumelana namakhemikhali: Irabha ye-Silicone imelana namakhemikhali amaningi namafutha.
Irabha ye-Neoprene:
-Ukumelana nowoyela: Irabha ye-Neoprene inokumelana nowoyela okuhle kakhulu.
- Ukubambezeleka komlilo: Irabha ye-Neoprene ngokwemvelo ivimbela amalangabi.
- Ukumelana nesimo sezulu: Irabha ye-Neoprene imelana nokucekelwa phansi kokukhanya kwelanga ne-ozone.
