Ukwakhiwa Kwamafreyimu Esakhiwo Sensimbi Ehlanganisiwe Engajwayelekile YaseMelika
imininingwane yomkhiqizo
Izakhiwo zensimbi ezihlanganisiwe, ezakhiwe ngokumboza insimbi ngesendlalelo se-zinc ngokusebenzisa i-hot-dip galvanization, sezibe yitshe lesisekelo ekwakheni nasekukhiqizeni kwesimanje. Le nqubo ayigcini nje ngokuthuthukisa amandla emvelo ensimbi kodwa futhi inikeza ukumelana nokugqwala okumangalisayo, okwenza kube yinto ekhethwayo kuzo zonke izimboni ezahlukahlukene.
Izici Eziyinhloko
Insimbi egayiwe ichazwa yizici ezintathu eziyinhloko:
- Ukumelana Nokugqwala: Isembozo se-zinc sisebenza njenge-anode yomhlatshelo, sivikela insimbi engaphansi ekugqwaleni nasekuwohlokeni kwemvelo, ngisho nasezimweni ezinzima njengezindawo ezisogwini noma ezindaweni zezimboni.
- Ukuqina: Njengoba isikhathi esivamile sokuphila iminyaka engaphezu kuka-50 ezindaweni zasemakhaya kanye neminyaka engu-20-30 ezindaweni zasolwandle, insimbi eqinisiwe isebenza kangcono kunensimbi engalungiswanga izikhathi ezingu-3-5.
- Ukusebenza Kahle Kwezindleko: Nakuba izindleko zokuqala zokufaka ugesi ziphakeme kunokupenda, izidingo zayo zokulungisa eziphansi (isb., ukungapendi kabusha ngezikhathi ezithile) zinciphisa izindleko zesikhathi eside ngo-30–50%.
Izinzuzo Kunezinye Izindlela
Uma kuqhathaniswa nezinye izinto zokwakha ezifana nokhuni, ukhonkolo, noma insimbi engalungiswanga, insimbi ehlanganisiwe inikeza izinzuzo ezihlukile:
| Inzuzo | Insimbi Egayiwe | Insimbi Engaphathwanga | Ukhonkolo |
|---|---|---|---|
| Ukumelana Nokugqwala | Kuhle kakhulu (ukumbozwa kwe-zinc) | Kubi (kuthambekele ekugqwaleni) | Okumaphakathi (kusengozini yokuqhekeka) |
| Isilinganiso Sesisindo-kuya-Amandla | Okuphezulu (okulula kodwa okuqinile) | Iphakeme kodwa inzima kune-galvanized | Iphansi (inzima, idinga ukwesekwa okwengeziwe) |
| Isivinini Sokufaka | Okusheshayo (izingxenye ezilungisiwe kusengaphambili) | Okumaphakathi (kudinga ukupendwa endaweni) | Kancane kancane (kudingeka isikhathi sokuphulukisa) |
| Umthelela Wezemvelo | Ingaphinde isetshenziswe ngo-100%, ine-carbon ephansi | Ukushintsha okuphezulu (okuvamile) | Ukukhishwa okuphezulu (kokukhiqizwa kukasimende) |
Izicelo
Ukuguquguquka kwensimbi egayiwe kuholela ekusetshenzisweni kwayo ku:
- Ukwakhiwa: Uphahla, ozimele bezakhiwo, namabhuloho (isb., izisekelo zekhebula zeGolden Gate Bridge).
- Ingqalasizinda: Imibhoshongo yokuxhumana, izinsika zokudlulisa ugesi, kanye nezivikelo zomgwaqo.
- Izimoto: Ozimele bezimoto kanye nezinqola zangaphansi, lapho ukumelana nokugqwala kubaluleke kakhulu.
- Ezolimo: Ozimele bezindlu zokugcina izithombo, ama-silo, kanye nemishini yasepulazini evezwe emswakama namakhemikhali.
Amathrendi Esikhathi Esizayo
Ikusasa lensimbi eqinisiwe lisekuqanjweni nasekusimeni:
- Izembozo Ezithuthukisiwe: Izembozo ze-hybrid zinc-aluminium-magnesium (ZAM) ziyavela, zinikeza ukumelana nokugqwala okungcono ngokuphindwe kabili kuya kathathu kune-galvanization yendabuko, ilungele amapulazi omoya asogwini kanye nezindawo ezinosawoti omningi.
- Ukukhiqiza Okuluhlaza: Izinqubo zokusebenzisa i-galvanization ezisebenzisa amandla amaningi (isb., amabhati e-zinc asezingeni eliphansi lokushisa) kanye nokuhlanganiswa kwensimbi ephinde yasetshenziswa kunciphisa ukukhishwa kwekhabhoni ngo-15–20%.
- Izakhiwo Ezihlakaniphile: Ukuhlanganiswa nezinzwa zokuqapha ubuqotho bokumboza ngesikhathi sangempela, okuvumela ukulungiswa okubikezelayo nokwandisa isikhathi sokuphila.
Isiphetho
Insimbi egayiwe isalokhu iyinto ebalulekile engqalasizinda yomhlaba wonke, ihlanganisa amandla, ukuqina, kanye nokusimama. Njengoba izimboni zibeka phambili ukuqina kwesikhathi eside kanye nemikhuba enobungani nemvelo, indima yayo izokhula, iqhutshwa yintuthuko yezobuchwepheshe ekumbozeni nasekukhiqizeni. Konjiniyela nabakhi bezakhiwo, insimbi egayiwe akuyona nje into ekhethwayo kodwa iyindlela yokutshala imali ehlelekile ekuthembekeni nasekusebenzeni.
