Uma kukhulunywa ngokusebenza kwe-port crane, ubunjiniyela be-offshore, ukugibela kokuzijabulisa, ngisho nezintambo zezingubo zansuku zonke, ukukhetha intambo yocingo efanele ngokuvamile kungaba yinkinga. Ingqondo yokuqala yabantu abaningi ukukhetha intambo yensimbi engenalutho yendabuko-phela isisetshenziswe iminyaka eminingi futhi ayibizi. Kodwa-ke, eminyakeni yakamuva, intambo yensimbi{3}}yeplasitiki ibilokhu izuza isabelo semakethe, ivela yonke indawo kusukela{4}}kuzinto zokusebenza eziphezulu kuya ezinhlelweni ezijwayelekile zasendlini. Pho kungani abantu abaningi beshiya intambo yensimbi engenalutho bethandaipulasitiki-yentambo yocingo enamathiselwe?
1. Umehluko omkhulu ekumelaneni nokugqwala
Iyiphi i-drawback enkulu yezintambo zensimbi ezingenalutho? Ukugqwala.
Kungakhathaliseki ukuthi zenziwe ngensimbi engagqwali noma ngensimbi, lezi zintambo zizogcina zingaphumeleli lapho zivezwe endaweni enomswakama, isifutho sikasawoti ogwini, noma amagesi abolayo ezitshalweni zamakhemikhali. Uma ukugqwala sekungene ngaphakathi, amandla entambo ehla kakhulu, futhi ingozi yokuphuka kwentambo iyanda. Okubi kakhulu ukuthi ukugqwala kuvame ukuqala ngaphakathi; ngesikhathi ungayibona ngaphandle, intambo ngokuvamile isivele ingaphezu kokulungiswa.
Izintambo zensimbi eziboshwe ziyindaba ehlukile. Ingubo yangaphandle isebenza njengejazi lemvula lentambo. Umswakama, isifutho sikasawoti, noketshezi olune-asidi noma olune-alkali akukwazi nje ukufinyelela izintambo zensimbi ngokwazo. Kuzinhlelo zokusebenza ezifana nokuma kwemikhumbi, izindawo eziheha ipaki lamanzi, nezintambo ezidonsa kanzima zezakhiwo, impilo yesevisi yezintambo zensimbi eboshiwe ngokuvamile iba yinde ngokuphindwe izikhathi ezi-3 kuya kwezi-5 kunezingenalutho.
2. Gqoka Izinkinga
Ngesikhathi sokusetshenziswa, izintambo ezisentanjeni yensimbi engenalutho ziyagudlana, futhi izindawo ezixhumene nemigodi nezigubhu ziwohloka ngokushesha. Le nsimbi-eku{2}}i-metal friction iguga ngokuqondile ungqimba olungaphezulu noma ungqimba lwe-oxide, isheshisa ukugqwala futhi idale umjikelezo ononya.
I-plastic coating on plastic{0}}coated wire cables isebenza njengebhafa kanye nokothambisa. Nakuba ipulasitiki ngokwayo izoguga, iyazidela ukuze ivikeleizintambo zensimbingaphakathi. Uzoqaphela ukuthi izintambo zepulasitiki{1}}ezinamekwe zihamba kahle kakhulu kuma-pulley futhi zikhipha umsindo omncane kakhulu. Ikakhulukazi ezinhlelweni ezibandakanya ukugoba nokusonta okuphindaphindiwe{3}}njengama-crane hoisting systems kanye ne-elevator traction systems-ukuba khona kwe-plastic coating kunciphisa kakhulu-ukuguga okuncane phakathi kwezintambo.
3. Isici Sokuphepha Esiphakeme
- Okokuqala, izintambo zepulasitiki{0}}ezinamekwe ngensimbi azijwayele ukwakha ama-burrs noma izintambo eziphukile. Ngezintambo zensimbi ezingenalutho, uma umucu ugqashuka, izingcezu zensimbi ezincane zisebenza njengezinalithi zensimbi futhi zingasika kalula isikhumba somsebenzisi uma zinganakile. Le ngozi iyinkinga ikakhulukazi ezindaweni lapho amagilavu nezingubo zokuzivikela kuvame ukuthintana nentambo. I-plastic coating ihlanganisa zonke iziphetho eziphukile, iqinisekisa ukuthi indawo engaphezulu ihlala ibushelelezi futhi ipulasitiki{4}}imbozwe ngaso sonke isikhathi, ukuvikela ukulimala.
- Okwesibili, futhi leli yiphuzu abantu abaningi abangalinaki: ukugqoka kwepulasitiki kungenziwa ngemibala ehlukene. Lokhu akukona okobuhle kuphela-yize ngokuqinisekile kubukeka kungcono{2}}kodwa okokuhlonza ngokushesha. Isibonelo, emisebenzini-emikhulu yokuphakamisa, izintambo zezintambo zemithwalo ehlukene zihlukaniswa ngombala, okuvumela{5}}izisebenzi zasendaweni ukuthi ziqinisekise ngokushesha ukuthi kusetshenziswa intambo efanele yini. Emafekthri anemithetho eqinile yokuphepha, lolu hlelo lokuphatha olubonakalayo lungavimbela ngempumelelo izingozi.
4. Kwezinye izimo, izintambo zepulasitiki{1}}ziyisibopho.
Isibonelo, emigwaqweni yamakhebula yabagibeli nama-gondola okubuka indawo emapaki okuzijabulisa, imithetho yezokuphepha idinga ngokucacile ukuthi izintambo zezintambo zensimbi zibe nongqimba olungaphandle oluyisivikelo ukuze kuvinjelwe ukuphuka kwentambo ngengozi ekubangeleni ukulimala noma ukugqwala. Ngokufanayo, ezimbonini ezilungisa ukudla kanye nezindawo zokukhiqiza imithi, izintambo zensimbi ezingenalutho zingachitha izinhlayiya zensimbi noma ukugqwala, imikhiqizo engcolisayo, ngakho izintambo zepulasitiki{1}}zibalulekile. Kuma-canopies echibini ahlehliswayo kanye nezintambo ezilengayo ezifakwe emanzini, ukuchayeka isikhathi eside emanzini ane-chlorine kungenza izintambo zocingo ezingenalutho zingafaneleki nhlobo.
Ngokufanayo, izintambo ezilengayo zokuhlobisa kuma-facade-zezakhiwo eziphakeme kufanele zisebenze kokubili izinjongo zokusebenza nezobuhle. Izintambo eziboshiwe ziyatholakala ngemibala ongayenza ngendlela oyifisayo-emnyama, emhlophe, noma empunga{3}}ezivumela ukuthi zihlangane kalula nezindonga zamakhethini esakhiwo. Izintambo ezingenalutho azikwazi ukusetshenziswa ezinhlelweni ezinjalo.
Kunini Lapho Kusafanele Ukukhetha Intambo Yocingo Olungenalutho?
Nakuba izintambo zepulasitiki-ezinamekwe zinikeza izinzuzo eziningi, ukunamathela akuhlali kudingekile kukho konke ukusetshenziswa. Uma iphrojekthi ibeka kuqala amandla okugcina, ukunemba kwedayamitha, noma ukusebenza kwesakhiwo sokuqala sentambo{2}}noma uma idinga ukusebenza ngezinto ezithile ezisetshenziswayo{3}}intambo yocingo engenalutho isenazo izinzuzo zayo.
Kalula nje, uma ufuna ukusebenza kwemboni okuqondile, intambo yocingo engenalutho ingase ifaneleke kakhulu; uma ukhathazeke kakhulu ngokuvikeleka, ukuqina, ukubukeka, nolwazi lwansuku zonke lomsebenzisi, khona-keipulasitiki-yentambo yocingo enamathiselwengokuvamile ukukhetha okulinganiselayo.
Uma ukhetha umkhiqizo ofanele wephrojekthi yakho, cabangela indawo yokusebenza, izimfuneko zomthwalo, nezimo zokuwunakekela ngaphambi kokunquma ukuthi ukhetha intambo yensimbi engenalutho noma intambo yepulasitiki{0}}enamekiwe. Uma ungaqiniseki, zizwe ukhululekile ukusithinta.
