Uphononongo oluNzulu malunga nobudlelwane phakathi koBume kunye nokusebenza kweGalvalume Steel Coil

Kwimimandla efana nokwakha iindonga zamakhethini, izindlu zezixhobo, kunye neebrakethi ze-photovoltaic, ii-coil zentsimbi ze-galvalume zithatha indawo yee-coil zentsimbi zemveli ezigalelweyo njengokhetho oluqhelekileyo ngenxa yeenzuzo zazo ezimbini zokuxhathisa ukugqwala kunye nokusebenza kakuhle kweendleko. Nokuba yiGalvalume Steel Coil Price, into ephambili ekuthengeni ubunjineli, okanyeI-ASTM A792 GalvalumeIinkcukacha ezichazwe ngokucacileyo kwimigangatho yemveliso, umahluko ekusebenzeni okuphambili uvela kulawulo oluchanekileyo lokwakheka. Namhlanje, siza kuqala ngohlalutyo lokwakheka ukuze sityhile iimfihlo zokusebenza kweekhoyili zentsimbi ze-galvalume (kubandakanya iGalvalume Roll, iSteel Coil Galvalume, njl.njl.).
I. Uhlalutyo lweCore Composition yeGalvalume Steel Coil
Ukusebenza kweekhoyili zentsimbi ze-galvalume kugqitywa "zizinto ezisisiseko" kunye "nokwaleka." Ubungakanani obahlukeneyo bezinto buchaphazela ngokuthe ngqo iimeko ezifanelekileyo zemveliso yokugqibela. Umzekelo, uyilo lokwakheka kweGalvalume Steel Coil Az150, olufuna ukumelana nokugqwala okuphezulu, lwahluke kakhulu kolo lweGalvalume Coil eqhelekileyo.
1. Ukwakheka kweCoating: "Umlinganiselo weGolide" weAluminiyam, iZinc, kunye neSilicon

Ukwaleka kwe-aluminium-zinc akuyonto inye yesinyithi, kodwa yinkqubo ye-alloy ye-aluminium (55%), i-zinc (43.5%), kunye ne-silicon (1.5%). Olu luhlu lusisombululo esifanelekileyo esiqinisekisiweyo ngokusebenza ixesha elide:
* I-Aluminiyam (Al): “Isiseko esingamelani nokugqwala” somgqumo. I-Aluminiyam yenza ifilimu ye-Al₂O₃ oxide exineneyo kumphezulu wekhoyili yentsimbi, enokumelana nokugqwala kwiindawo ezinzima ezifana nemvula ene-asidi kunye ne-salt spray. Esi sesona sizathu siphambili sokuba iikhoyili zentsimbi ezigqunywe yi-aluminium-zinc zinokumelana nokugqwala okuphindwe kathathu ukuya kahlanu kuneekhoyili zentsimbi eziqhelekileyo ezigqunywe yi-galvanized;
* I-Zinc (Zn): Idlala indima "yokukhusela i-anode yedini." Xa i-coating ikrwelwa, i-zinc iya kusabela ngokukhethekileyo ne-oxygen ukuthintela intsimbi esisiseko ukuba ingagqwali. Kwangaxeshanye, ubukho be-zinc bunokuphucula ukuguquguquka kwe-coating, okwenza kube lula kwi-Galvalume Roll ukugoba nokunyathela;
* I-Silicon (Si): Isombulula ingxaki "yokunamathela kwe-coating". I-Silicon inokuthintela impendulo phakathi kwe-aluminium kunye ne-iron ukwenza ii-compounds ze-Fe-Al ezibuthathaka neziqinileyo, inciphisa umngcipheko wokuxobuka kwe-coating. Isiphumo sokuzinza kwe-silicon sibaluleke kakhulu kwi-Galvalume Steel Coil Az150 etyebileyo (i-AZ150 imele ubunzima be-150g yokubeka i-coating nge-square meter).
2. Ukwakhiwa kweSubstrate: "Isiqinisekiso esiSiseko" seNtsimbi eKhabhoni ephantsi

Isiseko seiikhoyili zentsimbi zegalvalumeikakhulu yintsimbi enekhabhoni ephantsi (umxholo wekhabhoni ≤0.12%), yongezwa ngamanani amancinci e-manganese (0.3-0.6%) kunye ne-phosphorus (≤0.045%): I-Carbon (C): Umxholo wekhabhoni ogqithisileyo uya kwenza i-substrate ibe nzima kakhulu, nto leyo eyenza ukuba iqhekezeke ngexesha lokucubungula; umxholo ophantsi kakhulu uya kunciphisa amandla e-coil yentsimbi. Ke ngoko, umxholo wekhabhoni wentsimbi enekhabhoni ephantsi kufuneka ulawulwe ngokungqongqo ngaphakathi "koluhlu lwamandla kunye nolungelelwaniso lokuqhubekeka"; I-Manganese (Mn): Inani elincinci le-manganese linokuphucula amandla okuvelisa i-substrate ngaphandle kokuchaphazela kakhulu ukuguguleka, okwenza ifaneleke kwizicelo zokuthwala umthwalo (ezifana ne-galvalume ye-coil yentsimbi kwiibrakethi ze-photovoltaic); I-Phosphorus (P): I-Phosphorus yonyusa ukubuthathaka kwentsimbi, ngoko ke umxholo we-phosphorus kwi-substrate kufuneka ulinganiselwe ngokungqongqo, nto leyo nayo yenye yeempawu ezichazwe ngokucacileyo kumgangatho we-ASTM A792 Galvalume.
II. Ubudlelwane Phakathi Kobume kunye Neempawu Eziphambili Zokusebenza Ukuqonda ubume kusenza sibone ngokucacileyo ukuba kutheni abanyeIikhoyili zeGalvalumezilungele ukwakhiwa ngaphandle ngelixa ezinye zilungele ii-liner zezixhobo—into ephambili kukuba umahluko wokusebenza uvela kuhlengahlengiso lokwakheka.

1. Ukumelana Nokugqwala: Umxholo weAluminiyam Umisela "Inqanaba Lokhuseleko" Ukumelana nokugqwala yeyona nto iphambili ekukhuphisana ngayoimiqulu yegalvalume, kwaye ubudlelwane bayo nokwakheka kwayo buthe ngqo ngokukodwa: Xa umxholo we-aluminiyam wengubo unyuka ukusuka kwi-50% ukuya kwi-55%, uxinano lwefilimu ye-Al₂O₃ oxide luphucuka kakhulu. Kwiindawo zokutshiza ngetyuwa elunxwemeni lolwandle, ixesha lokugqwala kwentsimbi yentsimbi linokwandiswa ukusuka kwiminyaka eli-10 ukuya kwiminyaka engaphezu kwama-20. Ukuba umxholo we-silicon ungaphantsi kwe-1%, kuya kukhokelela ekunciphiseni ukunamathelana phakathi kwengubo kunye ne-substrate, okwenza ukuba ingubo ithambekele ekuqhumeni kwiimvavanyo zokutshiza ngetyuwa; ukuba ingaphezulu kwe-2%, iya kwandisa ubulukhuni bengubo, ngaloo ndlela inciphise ukuqina kokumelana nokugqwala. Kukwakho nesizathu sokuba iGalvalume Steel Coil AZ150 inokumelana nokugqwala okunamandla kune-AZ100 (ingubo ye-100g ngemitha yesikwere) - ayigcini nje ngokuba ingubo ityebile, kodwa umlinganiselo we-aluminium-zinc-silicon ukwafaneleka ngakumbi kwiimfuno zokhuseleko eziphezulu.
2. Iipropati zoomatshini: Ulwakhiwo lwe-Substrate lulawula "amandla kunye nokuqhubekeka kokusebenza"
Amandla: Xa kukho ukunyuka kwe-0.1% kumxholo we-manganese we-substrate, amandla okuvelisa i-coil yentsimbi anokunyuka nge-5-8 MPa. Ke ngoko, kwi-Galvalume Steel Coil esetyenziswa kwizicelo zokuthwala umthwalo, umxholo we-manganese ulawulwa kwi-0.5-0.6%.
Ukuqhubekeka: Kwizicelo ezifuna ukunyatheliswa okuntsonkothileyo, njengee-casings zezixhobo, kukhethwa ii-substrates ezinomxholo wekhabhoni ≤0.1%, ngelixa umxholo we-silicon womgqumo uncitshiswa uye kwi-1.5% ukuthintela ukuqhekeka komgqumo ngexesha lokunyatheliswa. 3. Ukumelana nobushushu obuphezulu: Inzuzo ye-aluminium "yokuzinza kobushushu obuphezulu"
Iqondo lokunyibilika kwe-aluminium (660℃) liphezulu kakhulu kunele-zinc (419℃), ngoko ke, ukumelana nobushushu obuphezulu kwee-coils ze-zinc steel ze-alumined kungaphezulu kakhulu kunee-coils ze-galvanized steel:
Kwiindawo ezingaphantsi kwama-200℃ (ezifana nee-linings ze-oven), ukusebenza kwe-coating kuzinzile;
Nokuba kubushushu obuphezulu bexesha elifutshane obuyi-300℃, ifilimu ye-Al₂O₃ inokuthintela ukubola kwe-oxidation, nto leyo ebangela ukuba iGalvalume Roll ifaneleke kwiitshimini kunye ne-cladding yepayipi enobushushu obuphezulu.

III. Ubudlelwane Phakathi Kokwakhiwa, Ukusebenza, kunye neXabiso leGalvalume Steel Coil

Abantu abaninzi bayazibuza ngexesha lokuthenga: Kutheni umahluko wexabiso leGalvalume Coil eneempawu ezifanayo ungafikelela kwi-100-200 RMB/ton? Ngokwenyani, umahluko wexabiso ubonakalisa ixabiso lezinto: Ixabiso lokugquma: Ixabiso lemarike le-aluminium liphindwe ka-2-3 kunele-zinc. Ke ngoko, umxholo we-aluminium ophezulu kwi-coating (umz., AZ150 xa kuthelekiswa ne-AZ90), ixabiso liphezulu, kwaye ixabiso leGalvalume Steel Coil liphezulu. Ixabiso lezinto ezisisiseko: Okukhona umxholo we-manganese uphezulu kwaye umxholo we-phosphorus uphantsi kwintsimbi ye-carbon ephantsi, kokukhona ixabiso lokunyibilikisa liphezulu, kwaye ixabiso leGalvalume Steel Coil liphezulu. Ixabiso eliqhelekileyo: Iimveliso ezihambelana nomgangatho we-ASTM A792 Galvalume zinolawulo oluqinileyo lokunyamezelana kwezixhobo (umz., ukuphambuka komxholo we-aluminium ≤ ±1%), izinga eliphezulu le-scrap ngexesha lokuvelisa, kunye nexabiso eli-5-8% liphezulu kuneemveliso ezingezizo ezisemgangathweni. IV. Ityala leSicelo esiSebenzayo: Ukubaluleka koKhetho loBumbe

Iprojekthi yokwakha elunxwemeni ithelekise iintlobo ezimbini zeekhoyili zentsimbi zegalvalume: Ikhoyili yeGalvalume eqhelekileyo (i-aluminium engama-50%, i-silicon eyi-1%): Ukugqwala kwendawo kwavela emva kweminyaka emi-3 yokusetyenziswa; Ikhoyili yentsimbi yeGalvalume Az150 (i-aluminium engama-55%, i-silicon eyi-1.5%), ehambelana ne-ASTM A792: Akukho kugqwala okubalulekileyo emva kweminyaka emi-5 yokusetyenziswa, kwaye akukho kugqwala ngexesha lokuchaphazeleka yinkanyamba (iipropati eziphezulu zoomatshini). Ekugqibeleni le projekthi ikhethe le yokugqibela. Nangona ixabiso lokuqala lekhoyili yentsimbi yeGalvalume yayiphezulu nge-150 RMB/ton, ubomi benkonzo bandiswa ngeminyaka engaphezu kwe-10, nto leyo eyabangela ukuba ixabiso lexesha elide liphantsi.

Isiphelo: Uyilo lokwakheka kweekhoyili zentsimbi ze-galvalume yinkqubo "ehambelana ngokuchanekileyo neemfuno": I-AZ150 (i-aluminium ephezulu, i-silicon ephezulu) ikhethwa ngenxa yokumelana nokugqwala okuphezulu; ii-silicon ezisezantsi, ii-substrates zekhabhoni ephantsi zikhethwa ngenxa yokucubungula okuntsonkothileyo; kwaye iimveliso ezisemgangathweni ze-ASTM A792 zikhethwa ngenxa yeeprojekthi zokuthumela ngaphandle. Ngophuhliso lwexesha elizayo lwamashishini e-photovoltaic kunye namandla amatsha, ukulungiswa kokwakheka (njengokongeza inani elincinci lezinto ezinqabileyo zomhlaba ukuphucula ukumelana nokugqwala) kuya kuba yindlela ebalulekileyo yophuhliso lweekhoyili zentsimbi ze-zinc ezenziwe nge-aluminium, nto leyo eyandisa ngakumbi imida yazo yokusetyenziswa.
