Ucwaningo Olujulile Ngobudlelwano Phakathi Kokwakheka Nokusebenza Kwe-Galvalume Steel Coil

Emasimini afana nokwakha izindonga zamakhethini, izindlu zemishini, kanye nama-bracket e-photovoltaic, ama-coil ensimbi e-galvalume athatha indawo yama-coil ensimbi e-galvalume kancane kancane njengenketho evamile ngenxa yezinzuzo zawo ezimbili zokumelana nokugqwala kanye nokusebenza kahle kwezindleko. Kungakhathaliseki ukuthi yi-Galvalume Steel Coil Price, into ebalulekile ekuthengeni kobunjiniyela, nomaI-ASTM A792 GalvalumeUma imininingwane ichazwe ngokucacile ezindinganisweni zokukhiqiza, umehluko ekusebenzeni okuyinhloko uvela ekulawulweni okunembile kokwakheka. Namuhla, sizoqala ngokuhlaziywa kokwakheka ukuze siveze izimfihlo zokusebenza kwamakhoyili ensimbi e-galvalume (kufaka phakathi i-Galvalume Roll, i-Steel Coil Galvalume, njll.).
I. Ukuhlaziywa Kokwakheka Okuyinhloko Kwekhoyili Yensimbi Ye-Galvalume
Ukusebenza kwamakhoyili ensimbi e-galvalume kunqunywa kokubili "izinto eziyisisekelo" kanye "nokwemboza." Izilinganiso ezahlukene zezingxenye zithinta ngqo izimo ezifanele zomkhiqizo wokugcina. Isibonelo, ukwakheka kokwakheka kwe-Galvalume Steel Coil Az150, okudinga ukumelana nokugqwala okuphezulu, kuhluke kakhulu kokwe-Galvalume Coil evamile.
1. Ukwakheka Kokumboza: “Isilinganiso Segolide” se-Aluminium, i-Zinc, ne-Silicon

Ukugqoka kwe-aluminium-zinc akuyona insimbi eyodwa, kodwa uhlelo lwe-alloy lwe-aluminium (55%), i-zinc (43.5%), kanye ne-silicon (1.5%). Lesi silinganiso siyisisombululo esihle kakhulu esiqinisekiswa ngokusebenza kwesikhathi eside:
* I-Aluminium (Al): “Ingqikithi engamelani nokugqwala” yengubo. I-Aluminium yakha ifilimu ye-Al₂O₃ oxide ejiyile ebusweni be-coil yensimbi, engamelana nokugqwala okuvela ezindaweni ezinzima njengemvula ene-asidi kanye ne-salt spray. Lesi yisizathu esiyinhloko sokuthi ama-coil ensimbi ambozwe nge-aluminium-zinc anokumelana nokugqwala okuphindwe kathathu kuya kahlanu kune-coils yensimbi evamile egayiwe;
* I-Zinc (Zn): Idlala indima “yokuvikela i-anode yomhlatshelo.” Uma isembozo siklwejwa, i-zinc izosabela kangcono nomoya-mpilo ukuvimbela insimbi eyisisekelo ekugqwaleni. Ngesikhathi esifanayo, ukuba khona kwe-zinc kungathuthukisa nokuguquguquka kwesembozo, okwenza kube lula nge-Galvalume Roll ukugoba nokunyathela;
* I-Silicon (Si): Ixazulula inkinga “yokunamathela kokumboza”. I-Silicon ingavimbela ukusabela phakathi kwe-aluminium nensimbi ukuze kwakheke ama-compounds e-Fe-Al aqinile futhi aqinile, okunciphisa ingozi yokumboza ukucobeka. Umphumela wokuzinza we-silicon ubaluleke kakhulu kwi-Galvalume Steel Coil Az150 ejiyile (i-AZ150 imele isisindo sokumboza esingu-150g ngemitha yesikwele).
2. Ukwakheka kwe-Substrate: “Isiqinisekiso Esiyisisekelo” seNsimbi Engenakhabhoni Ephansi

Isisekelo seamakhoyili ensimbi e-galvalumeikakhulukazi insimbi enesikhabhoni esincane (okuqukethwe kwekhabhoni ≤0.12%), ehambisana nenani elincane le-manganese (0.3-0.6%) kanye ne-phosphorus (≤0.045%): I-Carbon (C): Okuqukethwe kwekhabhoni ngokweqile kuzokwenza i-substrate ibe nzima kakhulu, okwenza ithambekele ekuqhekekeni ngesikhathi sokucubungula; okuqukethwe okuphansi kakhulu kuzonciphisa amandla e-coil yensimbi. Ngakho-ke, okuqukethwe kwekhabhoni kwensimbi enesikhabhoni esincane kumele kulawulwe ngokuqinile ngaphakathi "kwebanga lokulinganisela kwamandla nokucutshungulwa"; I-Manganese (Mn): Inani elincane le-manganese lingathuthukisa amandla okukhiqiza e-substrate ngaphandle kokuthinta kakhulu ukuguquguquka, okwenza ifanelekele ukusetshenziswa kokuthwala umthwalo (njenge-galvalume ye-coil yensimbi yama-bracket e-photovoltaic); I-Phosphorus (P): I-Phosphorus ikhulisa ubuthakathaka bensimbi, ngakho-ke okuqukethwe kwe-phosphorus ku-substrate kumele kulinganiselwe ngokuqinile, okungenye yezinkomba ezichazwe ngokucacile ku-ASTM A792 Galvalume standard.
II. Ubudlelwano Phakathi Kokwakheka kanye Nezimpawu Zokusebenza Eziyinhloko Ukuqonda ukwakheka kusenza sibone ngokucacile ukuthi kungani abanyeAmakhoyili eGalvalumezifanele ukwakhiwa kwangaphandle kanti ezinye zifanelekela ama-liner emishini—ingqikithi itholakala ekwehlukeni kokusebenza okubangelwa ukulungiswa kwezakhi.

1. Ukumelana Nokugqwala: Okuqukethwe kwe-Aluminium Kunquma "Izinga Lokuvikela" Ukumelana nokugqwala kuwukuncintisana okuyinhloko kweimiqulu ye-galvalume, futhi ubudlelwano bayo nokwakheka kwayo buqondile kakhulu: Lapho okuqukethwe kwe-aluminium kwengubo kukhuphuka kusuka ku-50% kuya ku-55%, ubuningi befilimu ye-Al₂O₃ oxide buthuthuka kakhulu. Ezindaweni zokufutha ngosawoti ogwini lolwandle, isikhathi sokugqwala kwe-coil yensimbi singandiswa kusukela eminyakeni eyi-10 kuya eminyakeni engaphezu kwengu-20. Uma okuqukethwe kwe-silicon kungaphansi kuka-1%, kuzoholela ekunciphiseni ukunamathelana phakathi kwengubo kanye ne-substrate, okwenza ingubo ithambekele ekuqhumeni ekuhlolweni kokufutha ngosawoti; uma ingaphezu kuka-2%, izokwandisa ubuthakathaka bengubo, ngaleyo ndlela inciphise ukuqina kokumelana nokugqwala. Yingakho futhi i-Galvalume Steel Coil AZ150 inokumelana nokugqwala okunamandla kune-AZ100 (ingubo engu-100g ngemitha yesikwele) - akuyona nje kuphela ukuthi ingubo ikhuluphele, kodwa isilinganiso se-aluminium-zinc-silicon naso sifanelana kangcono nezidingo zokuvikela eziphezulu.
2. Izakhiwo Zomshini: Ukwakheka Kwe-Substrate Kubusa “Amandla Nokucutshungulwa”
Amandla: Ngokukhula ngakunye okungu-0.1% kokuqukethwe kwe-manganese kwe-substrate, amandla okukhiqiza ekhoyili yensimbi anganda ngo-5-8 MPa. Ngakho-ke, kwi-Galvalume Steel Coil esetshenziswa ezinhlotsheni zokuthwala umthwalo, okuqukethwe kwe-manganese kulawulwa ku-0.5-0.6%.
Ukucutshungulwa: Ngezinhlelo zokusebenza ezidinga ukunyatheliswa okuyinkimbinkimbi, njengezimbozo zemishini, kukhethwa ama-substrate anokuqukethwe kwekhabhoni okungu-≤0.1%, kuyilapho okuqukethwe kwe-silicon kwengubo kuncishiswa kube cishe ngu-1.5% ukuvimbela ukuqhekeka kwengubo ngesikhathi sokunyatheliswa. 3. Ukumelana Nokushisa Okuphezulu: Inzuzo ye-Aluminium "Yokuzinza Kokushisa Okuphezulu"
Indawo yokuncibilika kwe-aluminium (660℃) iphakeme kakhulu kuneye-zinc (419℃), ngakho-ke, ukumelana nokushisa okuphezulu kwama-coil ensimbi ye-zinc e-aluminium kuphakeme kakhulu kunokwama-coil ensimbi e-galvanized:
Ezindaweni ezingaphansi kuka-200℃ (njengezingqimba zehhavini), ukusebenza kokumboza kuzinzile;
Ngisho nangaphansi kwamazinga okushisa aphezulu esikhashana angu-300℃, ifilimu ye-Al₂O₃ ingavimbela ukubola kwe-oxidation, okuyisizathu esiyinhloko esenza ukuthi i-Galvalume Roll ifaneleke kuma-chimney kanye nokumbozwa kwamapayipi okushisa okuphezulu.

III. Ubudlelwano Phakathi Kokwakheka, Ukusebenza, kanye Nentengo Yekhoyili Yensimbi Ye-Galvalume

Abantu abaningi bayazibuza ngesikhathi sokuthenga: Kungani umehluko wentengo yeGalvalume Coil enezincazelo ezifanayo ungafinyelela ku-100-200 RMB/ton? Empeleni, umehluko wentengo ubonisa izindleko zezingxenye: Izindleko zokumboza: Intengo yemakethe ye-aluminium iphindwe ka-2-3 kune-zinc. Ngakho-ke, uma okuqukethwe kwe-aluminium kuphakeme ku-coating (isb., AZ150 uma kuqhathaniswa ne-AZ90), kulapho izindleko ziphakeme, futhi kulapho intengo yeGalvalume Steel Coil iphakeme. Izindleko zezinto eziyisisekelo: Uma okuqukethwe kwe-manganese kuphakeme futhi kuphansi okuqukethwe kwe-phosphorus ensimbini enekhabhoni ephansi, kulapho izindleko zokuncibilikisa ziphakeme, futhi kulapho intengo yeGalvalume Steel Coil ehambisanayo iphakeme. Izindleko ezijwayelekile: Imikhiqizo ehambisana ne-ASTM A792 Galvalume standard inokulawula okuqinile kokubekezelela izingxenye (isb., ukuphambuka kokuqukethwe kwe-aluminium ≤ ±1%), izinga eliphezulu lokusikwa ngesikhathi sokukhiqizwa, kanye nentengo ephakeme ngo-5-8% kunemikhiqizo engeyona ejwayelekile. IV. Icala Lokusebenza Elisebenzayo: Ukubaluleka Kokukhethwa Kokwakheka

Iphrojekthi yokwakha ogwini yaqhathanisa izinhlobo ezimbili zamakhoyili ensimbi e-galvalume: Ikhoyili Ejwayelekile ye-Galvalume (i-aluminium engu-50%, i-silicon engu-1%): Ukugqwala kwendawo kwavela ngemuva kweminyaka emi-3 yokusetshenziswa; Ikhoyili Yensimbi ye-Galvalume Az150 (i-aluminium engu-55%, i-silicon engu-1.5%), evumelana ne-ASTM A792: Akukho ukugqwala okuphawulekayo ngemva kweminyaka emi-5 yokusetshenziswa, futhi akukho ukuguquguquka ngesikhathi somthelela wesiphepho (izakhiwo ezinhle kakhulu zemishini). Iphrojekthi ekugcineni ikhethe lokhu okulandelayo. Nakuba intengo yokuqala ye-Galvalume Steel Coil yayiphezulu ngo-150 RMB/ton, impilo yesevisi yandiswa ngeminyaka engaphezu kwe-10, okwaholela ezindlekweni eziphansi zesikhathi eside.

Isiphetho: Ukwakheka kwamakhoyili ensimbi e-galvalume kuyinqubo "yezidingo ezihambisana kahle": I-AZ150 (i-aluminium ephezulu, i-silicon ephezulu) ikhethwa ngenxa yokumelana nokugqwala okuphezulu; ama-substrate e-silicon aphansi, i-carbon ephansi akhethwa ngenxa yokucubungula okuyinkimbinkimbi; kanti imikhiqizo ejwayelekile ye-ASTM A792 ikhethwa ngenxa yamaphrojekthi okuthumela kwamanye amazwe. Ngokuthuthuka kwesikhathi esizayo kwezimboni zamandla e-photovoltaic kanye nezimboni ezintsha zamandla, ukulungiswa kokwakheka (njengokwengeza inani elincane lezinto zomhlaba ezingavamile ukuthuthukisa ukumelana nokugqwala) kuzoba yisiqondiso esibalulekile sokuthuthukiswa kwamakhoyili ensimbi e-zinc e-aluminium, okwandisa imingcele yokusetshenziswa kwawo.
