Emhlabeni onamandla wokwakhiwa nokwakha, amakhoyili ensimbi enziwe nge-galvanized aqhamuke njengenketho ethandwayo kwabaningi. Ukuthandwa kwabo kuvela ekumelaneni kwabo nokugqwala, okubaluleke kakhulu ngezinhlaka ezivezwe izimo zemvelo ezinokhahlo. Kodwa-ke, uhambo olusuka ekukhetheni ikhoyili yensimbi efanelekile yesicelo kuhlelo lwayo lusihlekile ngezinselelo. Le ndatshana idlulela izihibe ezijwayelekile ekuthengeni okuphelele kwamakhoyili ensimbi ye-galvanized futhi kunikezela ukuqonda kokuthi ungazitholela kanjani ngempumelelo.
Ukuqonda amandla emakethe
Imakethe yomhlaba wonke ye Amakhoyili ensimbi enziwe nge-Galvenized abone ukukhula okuphezulu eminyakeni yamuva, eqhutshwa yisidingo esandayo esivela emikhakheni ehlukahlukene, kufaka phakathi ukwakhiwa, izimoto kanye nemishini. Le trajectory yokukhula kulindeleke ukuthi iqhubeke, ngosayizi wemakethe oveze ukufinyelela i-USD 250 billion ngo-2025, ikhula ngakuyi-5.2% ukusuka ngo-2020 kuya ku-2025.
Kunezici eziningana ezinikela kulokhu kunwebeka. Okokuqala, i-boom embonini yezokwakha, ikakhulukazi emnothweni ovelayo, iholele ekuhlaselweni kwamandla amakhoyili ensimbi ye-galvanized. Lawa makhoyili athandwa ngokuqina kwawo kanye nokumelana nokugqwala, okwenza babe nelungele ukuphahla, ukuxazulula kanye nezinye izinhlelo zokusebenza. Okwesibili, ukuguquguquka komkhakha wezimoto obheke ezintweni ezingasindi futhi ezingamelana nokugqwala kubuye kubhekele isidingo sensimbi ye-galvanized.
Kodwa-ke, imboni ayikho ngaphandle kwezinselele zayo. Ukushintshashintsha okuguqukayo kwamanani entengo eluhlaza, ikakhulukazi i-zinc, ube nomthelela emingceleni yenzuzo yabakhiqizi nabahlinzeki. Ngaphezu kwalokho, ukungezwani okuqhubekayo kanye nezintela ezibekwe emikhiqizweni yensimbi ziholele ekuhlinzekeni kokuphazamiseka, okuthinta ukutholakala nokutholakala kwamanani. Isibonelo, impi yokuhweba ye-US-China yaphumela kwimali ekhokhwayo engama-25% yensimbi engenisiwe, okuholela ekushintsheni kwamasu okuthola izinkampani eziningi.
Kulesi simo sokuncintisana, ukuqonda ama-nuances wemakethe kuba nge-paramoous kumabhizinisi afuna ukuthenga amakhoyili ensimbi enziwe ngezinsimbi. Akukhona nje ngokuthola imali enhle; Kumayelana nokuqinisekisa ikhwalithi, ukuvumelana, kanye nokwethenjwa ekuhlinzekeni.
Ukubaluleka kwekhwalithi ngaphezulu kwenani
Endaweni yamakhoyili ensimbi ye-galvanized, ikhwalithi akuyona nje i-buzzword; Kuyisichasiso esibucayi sokusebenza komkhiqizo nokuphila isikhathi eside. Kumabhizinisi, imiphumela yokuyekethisa ngekhwalithi ingaba nzima, okuholela ekuhlulekeni okuhlelekile, izindleko zokulungiswa kwemali, kanye nezingozi zokuphepha ezingaba khona.
Ukubaluleka kokulandela amazinga aphesheya akunakweqiwa. Izinhlangano ezifana ne-ASTM, iso, futhi En zibe setha izinqubo zokuhlola okuqinile nezinqubo zokuqinisekisa ukuqinisekisa ikhwalithi yemikhiqizo yensimbi egayiwe. Isibonelo, i-ASTM A653 / A653M iyincazelo ejwayelekile yeshidi lensimbi, i-zinc-camera (gallvanised) ngenqubo eshisayo ye-hot-dip yemikhiqizo yensimbi ehlanganisiwe. Ukuhambisana nalezi zindinganiso kuqinisekisa ukuthi amakhoyili ensimbi anezindawo ezidingekayo zemishini, izinsimbi zokuhlanganisa, kanye nokwakheka kwamakhemikhali ukwenza kahle kwizicelo zabo ezihlosiwe.
Kodwa-ke, lolu hambo lokuqinisekisa ikhwalithi lugcwele izinselelo. Enye yezingqinamba eziyinhloko ukuthambekela kokubeka phambili inani lentengo ngekhwalithi. Kwibhidi yokusika izindleko, amanye amabhizinisi angahle akhethe ama-Cheaper, imikhiqizo yangaphansi. Le ndlela ebona okufushane ingaholela kwizindleko ezibalulekile zesikhathi eside. Isibonelo, ucwaningo lweNational Association of Home Zakhi lwathola ukuthi izindleko zokwehluleka kwesakhiwo ekhaya zazizungeze ama- $ 40,000. Ukwehluleka okunjalo kuvame ukulandelwa emuva ekusetshenzisweni kwezinto eziphansi.
Elinye iphutha elivamile ukuntuleka kokuhlolwa okuphelele nokuhlolwa. Ngenkathi iningi labo abahlinzeki lihlinzeka ngezitifiketi, kubalulekile emabhizinisini aqhube inkuthalo yawo efanele. Ukubandakanya ama-ejensi wokuhlola avela eceleni ukuqinisekisa ikhwalithi yamakhoyili ensimbi kungagcina izinkampani ekulahlekelweni okungaba khona. Ngaphezu kwalokho, ukucwaningwa kwamabhuku njalo kwabahlinzeki kungaqinisekisa ukuthi banamathela ezincwadini okuvunyelwene ngazo namazinga.
Ukuzulazula kwezinkinga zezincazelo zensimbi
Amakhoyili ensimbi enziwe nge-galvanized awayona isixazululo esisodwa-sonke isixazululo. Beza emabangeni ahlukahlukene, ngalinye lihlanganiswe ngezinhlelo ezithile. Ukuqonda la mabanga kanye nemiphumela yawo kubalulekile kumabhizinisi ukwenza izinqumo zokuthengwa kwezinto ezinolwazi.
Amamaki ahlukene amakhoyili ensimbi ye-garyvanized anqunywa ngokuyinhloko ngesisindo sawo sokwenza umholo, okuwubukhulu be-zinc under. Lesi sisindo se-coating sibalulekile njengoba sithinta ngokuqondile ukumelana kwensimbi ekugqwaneni. Isibonelo, ikhoyili yensimbi yensimbi ye-g90 ye-g90 ye-g90, ngesisindo se-0.90 OZ / FT², inikeza ukumelana okuphezulu kokugqwala uma kuqhathaniswa nekhoyili ye-G60, enesisindo se-0.60 OZ / FT² / FT². Umehluko onjalo awuwona nje ufunda; banemiphumela yangempela emhlabeni. Ucwaningo lwe-American Galvanizers Association lwabonisa ukuthi izakhiwo ezisendaweni yasogwini, lapho zakhiwa nge-G90 Steel, ziye zanwetshwa isikhathi sokuphila kuka-20% uma siqhathaniswa nalezo ezakhelwe ngensimbi ye-G60.
Ngaphandle kwesisindo se-coating, izakhiwo zemishini zensimbi zibaluleke ngokulinganayo. Lezi zindawo, kufaka phakathi amandla ezithela, amandla ashukumisayo, namandla ashubile, anqume amandla wensimbi wokumelana nengcindezi nokushintshana. Isibonelo, ikhoyili yensimbi enemandla okuvuselela ama-PSI 50,000 angahle alungele izinhlelo zokusebenza zophahla, kanti enye inamandla okuvuselela ama-70,000 psi angafaneleka ngokwengeziwe ngezinto ezakhiwe. Imiphumela yokukhetha ibanga elingalungile ingabiza kakhulu. Icala elikhombayo liwukuwa kwesakhiwo sensimbi eChina ngonyaka ka-2009, okwakuthiwa ukusetshenziswa kwensimbi engaphansi ngempahla engenele yemishini.
Kodwa-ke, ubunzima obungapheli ngamabanga okuqonda. Inqubo yokuthengwa kwempahla ngokwayo ingaba yindawo yemayini. Amabhizinisi amaningi awela ogibeni lokuncika kuphela kwizincomo zabahlinzeki, ngaphandle kokwenza ucwaningo lwazo. Lokhu kungaholela ekuziphatheni okungafani phakathi kwezinto zensimbi nezidingo zephrojekthi. Isibonelo, iphrojekthi yokwakha eDubai yabhekana nokubambezeleka okubalulekile futhi ibiza kakhulu lapho kutholakala ukuthi amakhoyili ensimbi angenazo izidingo ezicacisiwe, okuholela ebunzimeni bokubumba.
Ukuzulazula kulelu nzima, amabhizinisi kufanele abeke phambili imfundo nokukhuthala okufanele. Ukuzibandakanya nochwepheshe bezimboni, ukuya ezokulaba ama-workshop, kanye nokwenza ucwaningo olunzulu kungahlomisa ochwepheshe bokuthengwa kolwazi abaludingayo. Ngaphezu kwalokho, ukukhuthaza ukuxhumana okusobala nabaphakeli, ukuqinisekisa ukuthi bayaziqonda izidingo namazinga athile kwiphrojekthi ngayinye, kubaluleke kakhulu. Ukucwaningwa kwamabhuku njalo nokuhlola kungaqhubeka nokuqinisekisa ukuthi amakhoyili ensimbi atholakalayo ahlangabezana nokucacisiwe okuvunyelwene ngakho.
Ukwakha ubudlelwano bomhlinzeki obuqinile
Ukuthengwa kwempahla yamakhoyili ensimbi ye-galvanized akuyona nje ubuhlobo bokushintshana; Kungubambiswano oludinga ukwethembana, okusobala, kanye nokuqonda okufanayo. Ukwakha nokugcina ubudlelwano obuqinile nabahlinzeki kungaba umehluko phakathi kokuthengwa kwempahla engenamthungo nezingqinamba ezibizayo.
Enye yezinselelo eziyinhloko ebudlelwaneni bomhlinzeki iqinisekisa ikhwalithi evumelanayo nokulethwa. Embonini yensimbi, lapho ukufunwa kungavuselela khona futhi izikhathi zokuhola kungaba yinde, ngisho nokuphambuka okuncane ngekhwalithi noma ukubambezeleka ekulethweni kungaba nemiphumela ebalulekile. Isibonelo, iphrojekthi enkulu yokwakha eNew York yabhekana nokubambezeleka kwezinyanga eziyisithupha ngenxa yokungakwazi komphakeli ukuletha ibanga elithile lensimbi ngesikhathi. Lokhu akupheleli kuphela izindleko kodwa futhi kwaqinisa ubudlelwano phakathi kosonkontileka kanye neklayenti.
Enye imidwebo evamile ukuntuleka kokusobala kokuxhumana. Ochwepheshe abaningi bokuthengwa kwempahla bathembela ekuvuseleleni ngezikhathi nangemibiko evela kubahlinzeki, ngezinye izikhathi abangadukisa. Indlela esebenzayo efaka phakathi ukucwaningwa kwamabhuku njalo nokuhlola, lapho amaqembu okuthengwa kwempahla angaqinisekisa ikhwalithi kanye nokucaciswa kwamakhoyili ensimbi. Ukubandakanya ama-ejensi okuhlola okuvela eceleni angaqhubeka nokuqinisa le nqubo, kuqinisekisa ukuhlolwa okungahlangene.
Ngaphezu kwalokho, kubalulekile ukukhuthaza isiko lokusebenzisana kanye nokukhula. Lokhu kubandakanya ukwabiwa kwemininingwane, izinselelo, kanye nempendulo. Isibonelo, uma umphakeli ebhekene nezinselelo zokuhlangabezana nesidingo esithile, kusiza ukuba nethimba lokuthengwa kwempahla lizokwaziswa kusenesikhathi. Lokhu kuvumela ukuxazulula inkinga ngokubambisana, ukuqinisekisa ukuthi womabili amaqembu angazulazula nezinselelo ndawonye.
Ekuphetheni, ngenkathi ukutholwa kwamakhoyili ensimbi ye-galvanized kungabonakala kuqondile, kugcwele izinselelo. Kodwa-ke, ngokubeka phambili ikhwalithi, ukucaciswa kokuqonda, kanye nokukhuthaza ubudlelwano bomhlinzeki obuqisayo, amabhizinisi angakwazi ukuzulazula kulezi zingibe futhi aqinisekise ukutholwa okuphumelelayo.
Ukugcina
Ukuthengwa kwempahla yamakhoyili ensimbi ye-galvanized kuyisici esibucayi samabhizinisi ekwakhiweni nasekukhiqizweni kwemikhakha. Ngenkathi izinselelo ziningi, ukubaluleka kokubeka phambili ikhwalithi, ukuqonda okuqondayo, nokwakha ubudlelwano bomhlinzeki obuqinile ngeke kuqedwe ngokweqile. Ngokunamathela kulezi zimiso, amabhizinisi awakwazi ukugwema kuphela izingibe ezijwayelekile kepha futhi aqinisekise isikhathi eside kanye nempumelelo yamaphrojekthi abo. Embonini lapho izigxobo ziphakeme khona, ezinolwazi nezinqumo zokuthengwa kwempahla okuthe xaxa yigumbi lokusebenza kahle.
