Abasebenzi bekhonkolo bangazuza ngokushintshela kumathuluzi wesandla ase-zinc-based avela kwithusi. Ababili laba bancintisana ngokwemibandela yobulukhuni, ukuqina, ukwakheka kwekhwalithi kanye nokuqedwa kobungcweti - kepha i-zinc inezinzuzo ezengeziwe.
Amathuluzi e-Bronze yindlela ethembekile yokufeza imiphetho ye-radius kanye namajoyinti wokulawula aqondile ngokhonkolo. Isakhiwo saso esiqinile sinokusatshalaliswa kwesisindo esifanele futhi singanikeza imiphumela yekhwalithi yobungcweti. Ngalesi sizathu, amathuluzi ethusi ngokuvamile ayisisekelo semishini eminingi yokuqedela kokhonkolo. Kodwa-ke, lokhu okuthandwayo kuza ngentengo. Izindleko zezimali nezabasebenzi zokukhiqizwa kwebhulokhi zidala ukulahleka emkhakheni, kepha akufanele kube njalo. Kukhona enye impahla etholakalayo-zinc.
Yize ukwakheka kwabo kuhlukile, ithusi ne-zinc banezinto ezifanayo. Bancintisana nomunye ngokwemibandela yobulukhuni, ukuqina, ukwakheka kwekhwalithi kanye nemiphumela yokwelashwa engochwepheshe. Kodwa-ke, i-zinc inezinzuzo ezengeziwe.
Ukukhiqizwa kwe-Zinc kunciphisa umthwalo osonkontileka nabenzi. Kuzo zonke ithuluzi lethusi elikhiqizwe, amathuluzi amabili ama-zinc angakufaka esikhundleni. Lokhu kunciphisa inani lemali elichithwe kumathuluzi ahlinzeka ngemiphumela efanayo. Ngaphezu kwalokho, ukukhiqizwa komenzi kuphephile. Ngokushintsha okuthandwa yimakethe ku-zinc, bobabili osonkontileka nabakhiqizi bazohlomula.
Ukubhekisisa okusondelene nokwakheka kwembula ukuthi ithusi liyi-alloy yethusi esetshenzisiwe iminyaka engaphezu kuka-5,000. Ngenkathi ebucayi yobudala bethusi, kwakuyinsimbi ejwayelekile futhi ehlukahlukene kakhulu futhi ehlukahlukene eyaziwa ngesintu, ikhiqiza amathuluzi angcono, izikhali, izikhali kanye nezinye izinto ezidingekayo ekusindeni komuntu.
Imvamisa kuyinhlanganisela yethusi ne-tin, i-aluminium noma i-nickel (njll.). Amathuluzi amaningi ukhonkolo angama-88-90% wethusi kanye ne-10-12% tin. Ngenxa yamandla ayo, ubunzima kanye nokukhahlela okuphezulu kakhulu, lokhu kuhlanganiswa kufanelekile kakhulu amathuluzi. Lezi zici ziphinde zinikeze umthwalo ophakeme othwala umthamo, ukumelana kahle nokuqina okuphezulu nokuqina okuphezulu. Ngeshwa, futhi kuthambekele ekugqwaneni.
Uma kuvezwa emoyeni okwanele, amathuluzi e-bronze azokwenza oxidize futhi ajike aluhlaza. Le nhlangano eluhlaza, ebizwa ngokuthi i-patina, imvamisa isibonakaliso sokuqala sokugqoka. I-patina ingasebenza njengesithiyo esivikelayo, kepha uma ama-chlorides (njengalawo asolwandle, inhlabathi noma izithukuthuku) akhona, la mathuluzi angakhula abe "yisifo sethusi". Lokhu ukubulawa kwamathuluzi anobunzima (asuselwa kuthuli). Kuyisifo esithathelwanayo esingangena ngensimbi futhi sikubhubhise. Lapho lokhu kwenzeka, cishe akukho ithuba lokukuvimba.
Umphakeli we-Zinc utholakala e-United States, evimbela umsebenzi owengazayo. Lokhu akugcinanga kuphela kuletha imisebenzi yezobuchwepheshe e-United States, kepha futhi kuncishiswe kakhulu izindleko zokukhiqiza kanye nenani lokuthengisa. Izinkampani zeMarshalltown
Ngoba i-zinc ayinayo enobunzima, "isifo sethusi" singagwenywa. Ngokuphambene nalokho, yinto yensimbi enesikwele sayo etafuleni lezikhathi nangezinhlobo ze-hexagonal (HCP) ze-crystal. Futhi kunobulukhuni obulinganiselayo, futhi ingenziwa malltable futhi kube lula ukucubungula emazingeni okushisa aphakeme kancane kunamazinga okushisa akhona.
Ngasikhathi sinye, bobabili i-Bronze kanye ne-zinc banobunzima obulungele amathuluzi (ezilinganisweni ze-mohs ze-mohs of metha, i-zinc = 2,5; bronze = 3).
Ukuze ukhonkolo uqede, lokhu kusho ukuthi, ngokwezinkwa zokwakheka, umehluko phakathi kweBronze ne-zinc encane. Zombili zinikezela ngamathuluzi kakhonkolo anamandla aphezulu okulayisha, ukumelana okuhle kwe-abrasion, kanye nekhono lokukhiqiza cishe imiphumela efanayo yokuqeda. I-zinc ayinazo zonke izinto eziphilayo ezifanayo - iyi-Lightweight, kulula ukuyisebenzisa, imelana namabala ethusi, futhi ibiza kakhulu.
Ukukhiqizwa kweBronze kuthembela ezindleleni ezimbili zokukhiqiza (ukusakaza kwesihlabathi nokukhonkotha okufa), kepha nendlela ebibiza kakhulu kubakhiqizi. Umphumela uba ukuthi abakhiqizi bangadlula kulobu bunzima bezezimali kubasonkontileka.
Ukuphonsa kwesihlabathi, njengoba igama libonisa, ukuthulula i-Bronte Bronze ekubumbeni okuchithekayo okuchithwe ngesihlabathi. Njengoba isikhunta siyachithwa, umenzi kufanele athathe indawo noma aguqule isikhunta ngethuluzi ngalinye. Le nqubo ithatha isikhathi, okuholela emathuluzi ambalwa akhiqizwa futhi aphumelele ezindlekweni eziphakeme zamathuluzi ethusi ngoba ukuhanjiswa akunakuhlangabezana nesidingo esiqhubekayo.
Ngakolunye uhlangothi, ukukhonkotha die akuyona eyodwa-off. Lapho i-wequid yensimbi ithululelwa isikhunta sensimbi, iqiniswe futhi isuswe, isikhunta siphinde silungele ukusetshenziswa ngokushesha. Kwabakhiqizi, okuwukuphela kokwebizi kwale ndlela ukuthi izindleko zokubumba okukodwa okufezayo zingaba phezulu njengamakhulu ezinkulungwane zamaRandi.
Kungakhathaleki ukuthi iyiphi indlela yokusebenzisa umkhiqizi akhetha ukuyisebenzisa, ukugaya nokudonsela phansi kuyabandakanyeka. Lokhu kunikeza amathuluzi ethusi akwelashwa okubushelelezi, okulungele ukulungele nokulungele ukusetshenziswa komhlaba. Ngeshwa, le nqubo idinga izindleko zabasebenzi.
Ukugaya nokudonsela phansi kuyingxenye ebalulekile yokukhiqizwa kwamathuluzi ethusi, futhi kuzokhiqiza uthuli oludinga ukugcwala okusheshayo noma umoya omncane. Ngaphandle kwalokhu, abasebenzi bangahle bahlupheke ngenxa yesifo esibizwa nge-pneumoconiosis noma "pneumoconiosiosis", okubangela izicubu zesilonda ukuba ziqongelele emaphashini futhi zingadala izinkinga ezinkulu zamaphaphu.
Yize lezi zinkinga zempilo zivame ukugxila emaphashini, ezinye izitho zomzimba nazo zisengozini. Ezinye izinhlayiya zingacibilikisa egazini, zivume ukuthi zisakazeke emzimbeni wonke, zithinta isibindi, izinso kanye nengqondo. Ngenxa yalezi zimo eziyingozi, abanye abakhiqizi baseMelika abasazimisele ukubeka izisebenzi zabo engozini. Esikhundleni salokho, lo msebenzi ukhishwa. Kepha ngisho nalabo abakhiqizi abangaphandle babize ukumiswa kokukhiqizwa kwethusi nokugaya okuhilelekile.
Njengoba kunabakhiqizi abambalwa futhi abambalwa be-bronzes ekhaya nakwamanye amazwe, ama-bronzes azoba nzima kakhulu ukuthola, okuphumela ngamanani angenangqondo.
Ukuze ukhonkolo ukhokhe, umehluko phakathi kweBronze ne-zinc encane. Zombili zinikezela ngamathuluzi kakhonkolo anamandla aphezulu okulayisha, ukumelana okuhle kwe-abrasion, kanye nekhono lokukhiqiza cishe imiphumela efanayo yokuqeda. I-zinc ayinazo zonke izinto eziphilayo ezifanayo - iyi-Lightweight, kulula ukuyisebenzisa, imelana nezifo zethusi, futhi ibiza kakhulu. Izinkampani zeMarshalltown
Ngakolunye uhlangothi, ukukhiqizwa kwe-zinc akuthwali lezi zindleko ezifanayo. Lokhu kungenxa yokwakhiwa kwesithando esisheshayo esisheshayo se-zinc-lead blast ngeminyaka yo-1960, esasisebenzisa ukupholisa okupholile nokuvunyelwa ukukhiqiza i-zinc. Imiphumela ilethe izinzuzo eziningi kubakhiqizi nabathengi, kufaka phakathi:
I-zinc ifana ne-bronze kuzo zonke izici. Zombili zinomthamo ophakeme wokuthwala umthwalo kanye nokumelana okuhle kwe-abrasion, futhi zilungele ubunjiniyela bekhonkolo, kanti i-zinc ithatha isinyathelo ngokuqhubekayo, ngokungenakuthezeka kwezifo zethusi kanye nokukhanya okulula, okusebenziseka kalula okunganikeza osonkontileka abanomphumela ofanayo ye.
Lokhu futhi kuyingxenye encane yezindleko zamathuluzi ethusi. I-zinc isuselwe e-United States, eqondile futhi ayidingi ukugaya nokukhulisa, ngaleyo ndlela kunciphise izindleko zokukhiqiza.
Lokhu akugcini nje kuphela kumaphaphu athuli kanye nezinye izimo zempilo ezibucayi, kepha kusho nokuthi abakhiqizi bangasebenzisa futhi okuncane ukukhiqiza okuningi. Lezi zigcini zizobe zidluliselwa osonkontileka ukubasiza ukuthi basindise izindleko zokuthenga amathuluzi aphezulu.
Ngazo zonke lezi zinzuzo, kungaba yisikhathi somkhakha ukuba ashiye iminyaka yethusi yamathuluzi ukhonkolo futhi amukele ikusasa le-zinc.
