Dab tsi yog Aluminium Coil yog thiab nws txhais li cas
Lub kauj yog nruam dov txhuas qhov txhab ntawm lub mandrel, muab rau cov neeg siv khoom uas pub nws mus rau hauv ib txoj kab slitting, yob qub, xovxwm, los yog coil txheej kab. Dimensions yog quoted raws li thickness los ntawm dav, nrog coil puab txoj kab uas hla, txheej txoj kab uas hla thiab coil hnyav hais cais, vim hais tias cov txiav txim seb lub kauj haum tus neeg muas zaub uncoiler. Cov khoom siv feem ntau yog zeb tiav, coated, thiab hlais - mus rau - dav, thiab cov txheej txheem npog cov ntawv thiab phaj hauv daim ntawv coil yog ASTM B209M, nrog EN 485-1, EN 485-2 thiab EN 485-4 npog cov txheej txheem, cov khoom siv kho tshuab thiab kev ua siab ntev rau sawb.
Oiling, ntug mob thiab winding nro tseem ceeb tshaj li lawv tshwm. Lub coil raug mob nruj heev yuav tsom iav los yog thaiv thaum them nyiaj; ib lub kauj uas tsis muaj roj nplua nyeem tsim nyog yuav tau qhab nia nyob rau hauv lub yob qub; unskinned npoo ntawm coated coil nthuav tawm liab qab hlau uas rusts nyob ib sab steel nyob rau hauv cia.
Qib thiab Tempers los ntawm Daim Ntawv Thov
| Daim ntawv thov | Hom alloy | Kub | Yog vim li cas |
|---|---|---|---|
| vov tsev thiab phab ntsa cladding | 3003, 3105, 5052 | H14, H24, H32 | Formability nrog sab nraum zoov corrosion kuj |
| Gutters thiab downspouts | 3003, 3105 | H14, H24 | Siv yob txoj kev tsis muaj ntug cracking |
| HVAC fin stock | 1100, 8011 | O, H22 | High thermal conductivity rau coil fins |
| Dej haus tuaj yeem ua rau lub cev | 3104 | H19 | Lub zog thiab thinning rau kos phab ntsa ironing |
| Tau kawg thiab tabs | 5182 | H19 | Siab zog thiab formability rau cov qhab nias lub hau |
| Automotive panels thiab tshav kub shields | 5182, 5754, 6016 | O, H22, T4 | Formability, dent kuj, yuag txuag |
| Cov cim thiab cov khoom siv vaj tse | 1100, 3003, 5052 | H14, H32 | Xim los yog anodic tiav thiab tiaj tus |
Lub zog sib txawv ntawm cov qib yog qhov tseem ceeb hauv kev tsim. 3003-H14 kauj yog teev ntawm 145 txog 186 MPa tensile nrog qhov tsawg kawg nkaus ntawm 124 MPa nyob rau hauv ASTM B209M, thaum 5052-H32 yog teev ntawm 228 txog 281 MPa tensile nrog qhov tsawg kawg nkaus tawm los ntawm 19. Qhov twg ib lub vaj huam sib luag spans nruab nrab ntawm kev txhawb nqa, qhov sib txawv ntawm lub zog tawm los hloov qhov kev sib nrug, tsis yog cov khoom siv xwb.
Coil txheej thiab nto tiav
Coil txheej siv qhov ua tiav ua ntej tsim, yog li txoj kab khoov tsis txhob liab qab. Lub tshuab polyvinylidene fluoride ntawm qhov tsawg kawg nkaus zaj duab xis tuab ntawm 25 micrometers rau ob lub-coat tsim yog ib qho kev qhia tshwj xeeb rau sab nrauv architectural ua hauj lwm raws li AAMA 2605, uas teev cov xim thiab gloss retention yuav tsum tau tom qab ceev thiab sab nraum zoov raug. Cov tshuab polyester raug nqi tsawg dua thiab tsim nyog hauv tsev lossis hauv ib puag ncig me me tab sis poob gloss sai dua sab nraum zoov.
Ob qhov kev sim txiav txim siab seb lub coil coated puas muaj sia nyob. T-kev xeem khoov, tau piav qhia hauv ASTM D4145, qib tawg tsis kam raws li cov sawb yog khoov rau ntawm nws tus kheej, thiab xaum tawv tawv lossis cuam tshuam kuaj xyuas zaj duab xis toughness. Txheej adhesion tom qab tsim yog kuaj nrog daim kab xev rau ASTM D3359. Lub kauj uas dhau qhov kev xeem adhesion ntawm daim ntawv tiaj tus tseem tuaj yeem ua tsis tau ntawm qhov khoov nruj, uas yog vim li cas T- khoov ntsuas yuav tsum tau teev tseg nrog lub vojvoog khoov lub yob yav dhau los siv tiag tiag.
Kev ua, Cia thiab tuav
Cov coils tau ua tiav nyob rau hauv peb txoj kev: slitting rau hauv cov coils nqaim, txiav - mus rau - ntev rau hauv cov ntawv tiaj tus, thiab ncaj qha pub rau hauv txoj kab sib sau los yog stamping. Xaiv lub coil hnyav tiv thaiv kev tuav lub peev xwm ntawm txoj kab, thiab qhia meej lub coil sab hauv txoj kab uas hla kom phim lub uncoiler mandrel. Kev sib tw nruj feem ntau yog siv tom qab dov los txhim kho flatness, uas yog ib qho tseem ceeb rau architectural panels uas pom cov roj- canning defect yog ib qho kev tsis lees paub.
Kev khaws cia txiav txim siab seb cov khoom puas tuaj txog hauv qhov siv tau. Coils yuav tsum tau muab cia rau hauv tsev, tawm hauv pem teb, nrog lub qhov muag kab rov tav los yog ntsug raws li tsim los rau lub ntim, thiab condensation yuav tsum tau zam vim nws ua rau dawb xeb ntawm zeb tiav thiab ntug staining ntawm coated Tshuag. Interleaved daim ntawv los yog zaj duab xis yuav tsum tau muab tshem tawm mus zuj zus, nyob rau hauv txoj kab nrog noj, es tsis stripped los ntawm tag nrho cov kauj uas ces zaum tsis muaj kev tiv thaiv.
Cov lus nug nquag
Q:Qhov twg aluminium coil qib yog feem ntau siv rau cov khoom tsim?
A: 3003 nyob rau hauv H14 los yog H24 rau vov tsev, cladding thiab gutters, nrog 3105 siv qhov twg me ntsis zog dua los yog txawv forming cwj pwm yuav tsum tau.
Q:Dab tsi yog qhov txawv ntawm H14 thiab H32 hauv ib lub kauj?
A: Ob leeg yog strain hardened, tab sis H14 yog hais txog ib theem hardness los ntawm tus txheej txheem ib theem zuj zus thiab H32 mus rau ib tug stabilized mob nyob rau hauv 5xxx tsev neeg. 5052-H32 yog qib marine thiab sab nraum zoov.
Q:Vim li cas coil txheej siv es tsis txhob pleev xim tom qab tsim?
A: Txheej ua ntej sib sau tawm ntawm txoj kab khoov npog, muab cov yeeb yaj kiab tuab tuab, thiab zam qhov blistering thiab xim txawv ntawm cov ncej- ua xim.
Q:Cov txheej txheem yooj yim ntsuas li cas?
A: Los ntawm T-kev sim khoov hauv ASTM D4145 thiab tom qab- khoov daim kab xev kuaj hauv ASTM D3359. T- khoov cov txiaj ntsig yuav tsum tau kuaj xyuas qhov khoov lub vojvoog siv hauv kev tsim khoom.
Q:Cov hlau twg yog siv rau cov dej haus tau lub cev?
A: 3104 nyob rau hauv H19 temper, xaiv rau lub zog thiab elongation xav tau los tiv thaiv phab ntsa ironing tsis splitting, thaum 5182-H19 yog siv rau xaus thiab tabs.
Q:Yuav tsum khaws cov coils li cas?
A: Nyob sab hauv tsev, tawm hauv av, txhawb nqa kom lub qhov muag tau khaws cia, thiab tiv thaiv los ntawm condensation. Cov dej sawv ntsug los yog cov dej tsis muaj dej ua rau cov xeb dawb ntawm cov zeb tiav thiab ntug staining ntawm cov khoom coated.
