Uphando malunga nokuBuyiselwa kweLanga kwiZixhobo zeeMoto kunye neendlela zokusetyenziswa kweeFayibha eziBuyiselwa yiLanga kwiZithuthi
Ngenxa yophuhliso olukhawulezileyo lweshishini leemoto, iimoto—ezisetyenziselwa ukuhamba okanye ukuthutha iimpahla—ziye zaba zizixhobo ezibalulekileyo ebomini babantu. Nangona iimoto zibonelela ngokulula, zikwabeka neengozi zokhuseleko, njengeengozi zendlela kunye nokutsha okuzenzekelayo. Ngenxa yendawo encinci kunye nezinto zangaphakathi ezinokutsha, xa umlilo uqhuma emotweni, kudla ngokuba nzima ukuwulawula, nto leyo ebeka ubomi kunye nempahla yabakhweli emngciphekweni. Ke ngoko, ukhuseleko lomlilo kwizithuthi kufuneka lube yingxaki enkulu kubasebenzisi.
Izizathu zomlilo wezithuthi ngokubanzi zingahlulwahlulwa zibe:
(1) Izinto ezinxulumene nezithuthi, kuquka iingxaki zombane, ukuvuza kwepetroli, kunye nokungqubana koomatshini okubangelwa kukuguqulwa okungafanelekanga, ukufakelwa, okanye ukulungiswa.
(2) Izinto zangaphandle, ezinje ngokungqubana, ukuqengqeleka, ukutshiswa, okanye imithombo yokutsha engajongwanga.
Izithuthi ezintsha zamandla, ezixhotyiswe ngeebhetri zamandla ezinobunzima obuphezulu, zisengozini enkulu yomlilo ngenxa yeesekethe ezimfutshane ezibangelwa kukungqubana, ukubhobozwa, ukubaleka kobushushu obuphezulu ngenxa yobushushu obuphezulu, okanye umbane ogqithisileyo ngexesha lokutshaja ngokukhawuleza.
01 Uphando malunga nokuLibazisa komlilo kwiZixhobo zeeMoto
Uphononongo lwezinto ezithintela umlilo lwaqala ngasekupheleni kwenkulungwane ye-19 eMelika. Ngenxa yokuqhubela phambili kwetekhnoloji kwiminyaka yakutshanje, kubekho iimfuno ezintsha zophando malunga nokuthintelwa komlilo kwezinto zangaphakathi zeemoto, ingakumbi kwezi ndawo zilandelayo:
Okokuqala, uphando olusekelwe kwingcamango malunga nokungatshisi komlilo. Kwiminyaka yakutshanje, abaphandi baseTshayina bagxininise kakhulu ekufundeni iindlela zokutsha kweefayibha ezahlukeneyo kunye neeplastiki, kunye nokusetyenziswa kwezinto ezithintela umlilo.
Okwesibini, uphuhliso lwezinto ezithintela umlilo. Okwangoku, kukho iintlobo ezininzi zezinto ezithintela umlilo ezisaphuhliswayo. Kumazwe ngamazwe, izinto ezifana ne-PPS, i-carbon fiber, kunye ne-glass fiber zisetyenziswe ngempumelelo kumashishini ahlukeneyo.
Okwesithathu, uphando ngamalaphu athintela umlilo. Amalaphu athintela umlilo kulula ukuwavelisa kwaye asebenza kakuhle kakhulu. Nangona amalaphu ekotoni athintela umlilo sele ephuhlisiwe kakuhle, uphando ngamanye amalaphu athintela umlilo luseluncinci eTshayina.
Okwesine, imigaqo kunye neendlela zokuvavanya izinto ezithintela umlilo.
Izinto zangaphakathi zeemoto zingahlulwahlulwa ngokubanzi zibe ziindidi ezintathu:
- Izinto ezisekelwe kwifayibha (umz., izihlalo, iikhaphethi, iibhanti zokhuseleko)—zezona zisetyenziswa kakhulu kwaye zidibana ngqo nabakhweli.
- Izinto ezenziwe ngeplastiki.
- Izinto ezisekwe ngerabha.
Izinto ezisekelwe kwifayibha, ezitsha kakhulu kwaye zikufutshane nabakhweli, zibeka umngcipheko omkhulu xa kutsha. Ukongeza, ezinye izinto zesithuthi, ezifana neebhetri kunye neenjini, zikufutshane nezinto zelaphu, nto leyo enyusa amathuba okusasazeka komlilo. Ke ngoko, ukufunda ngokuthintela umlilo kwezinto zangaphakathi zeemoto kubalulekile ukuze kulibazise ukutsha nokubonelela abakhweli ngexesha lokubaleka.
02 Uhlu lweeFibers eziBandakanya ilangatye
Kwimisebenzi yelaphu lemizi-mveliso, amalaphu eemoto athatha inxaxheba enkulu. Imoto eqhelekileyo yomkhweli iqulethe malunga ne-20–40 kg yezinto zangaphakathi, uninzi lwazo ngamalaphu, kuquka nezigqubuthelo zezihlalo, imiqamelo, iibhanti zezihlalo, kunye neendawo zokubeka intloko. Ezi zinto zinxulumene kakhulu nokhuseleko lwabaqhubi nabakhweli, nto leyo ebangela ukuba kubekho iimpawu zokuthintela umlilo ukuze kuncitshiswe ukusasazeka komlilo kwaye kwandiswe ixesha lokubaleka.
Iifayibha ezithintela ilangatyezichazwa njengeefayibha ezingavuthiyo okanye ezingatshiyo ngokupheleleyo xa zidibene nomthombo womlilo, zivelisa amalangatye amancinci kwaye zizicime ngokukhawuleza xa umthombo womlilo ususiwe. I-Limiting Oxygen Index (LOI) isetyenziswa rhoqo ukulinganisa ukutsha, apho i-LOI engaphezulu kwe-21% ibonisa ukutsha okuphantsi.
Iifayibha ezithintela ilangatye zahlulwe zibe ziindidi ezimbini:
- Iifayibha eziBandayo zeLanga
Ezi fibers zinamaqela agcina ilangatye akhelwe ngaphakathi kwiitsheyini zazo zepolymer, ziphucula uzinzo lobushushu, zinyusa amaqondo obushushu okubola, zithintela ukuveliswa kwegesi evuthayo, kwaye zikhuthaza ukwakheka kwetsha. Imizekelo ibandakanya:
- Iifayibha ze-Aramid (umz., i-para-aramid, i-meta-aramid)
- Iifayibha zePolyimide (umz., iKermel, iP84)
- Iifayibha zePolyphenylene sulfide (PPS)
- Iifayibha zePolybenzimidazole (PBI)
- Iifayibha zeMelamine (umz., iBasofil)
Iifayibha zeMeta-aramid, ipolysulfonamide, ipolyimide, kunye nePPS sele zenziwe ngobuninzi eTshayina.
- Iifayibha eziGxothiweyo zeLanga eziPhindayo
Ezi fibers zifumana ukuthintela ilangatye ngokusebenzisa izongezo okanye unyango lomphezulu, kuquka:
- I-polyester egcina ilangatye
- I-nylon ethintela ilangatye
- I-viscose ethintela ilangatye
- I-polypropylene ethintela ilangatye
Iindlela zokuguqula ziquka i-copolymerization, i-blending, i-composite spinning, i-grafting, kunye ne-post-finishing.
03 Usetyenziso lweeFibers eziBambelelayo zeLangabi eziSebenza ngokuPhezulu ekuKhuseleni iiMoto
Izinto ezithintela ilangatye kwiimoto kufuneka zihlangabezane neemfuno ezithile ngenxa yemida yendawo. Ngokungafaniyo nezinye izinto ezisetyenziswayo, ezi zinto kufuneka zimelane nokutsha okanye zibonise amazinga okutsha alawulwayo (umz., ≤70 mm/min kwizithuthi zabakhweli).
Ukongeza, izinto ezifunekayo ziquka:
- Uxinano lomsi oluphantsi kunye nokukhutshwa kwegesi okuncinci okunobungoziukuqinisekisa ukhuseleko lwabakhweli.
- Iipropati ezichasene nokungashukumiukuthintela imililo ebangelwa ngumphunga wepetroli okanye ukuqokelelwa kothuli.
Izibalo zibonisa ukuba imoto nganye isebenzisa i-20–42 m² yezinto zelaphu, nto leyo ebonisa ukukhula okukhulu kwamalaphu eemoto. La malaphu ahlulwe ngokweentlobo ezisebenzayo nezihombisayo, kugxininiswa ngakumbi ekusebenzeni kwawo—ingakumbi ukungatshisi—ngenxa yenkxalabo yokhuseleko.
Iilaphu ezithintela ilangatye ezisebenza kakuhle zisetyenziswa kwezi zinto zilandelayo:
- Izigqubuthelo zezihlalo
- Iiphaneli zomnyango
- Iintambo zamatayara
- Iingxowa zomoya
- Iilinings zophahla
- Izixhobo zokuthintela isandi kunye nokukhusela ubushushu
Amalaphu angalukwanga enziwe nge-polyester, i-carbon fiber, i-polypropylene, kunye ne-glass fiber nawo asetyenziswa kakhulu ngaphakathi kweemoto.
Ukukhuthaza angaphakathi eemoto ezithintela ilangatye akupheleli nje ekuphuculeni ukhuseleko lwabakhweli kodwa kukwanegalelo kwimpilo-ntle yoluntu.
