Peb Lub Xeev ntawm Aluminium Ntawv Nyiaj
Cov ntawv ci yog muab cais ua ntej los ntawm lub xeev, uas yog cov mob metallurgical tshuav nyob rau hauv lub strip tom qab dov thiab ib qho annealing. Peb pawg lag luam yog cov ntawv tawv tawv, cov ntawv ci semi-hard thiab cov ntawv ci muag muag. Lub xeev txiav txim siab tuav cov cai, tsim tus cwj pwm thiab ntau yam ntawm cov txheej txheem hloov dua siab tshiab cov ntawv ci yuav txais, yog li nws yog thawj qhov kev txiav txim siab thaum sau ntawv tshwj xeeb. Temper designations siv los sau lub xeev ua raws EN 515 thiab ANSI H35.1.
Hard Foil
Cov ntawv ci tawv yog cov ntawv ci uas tau muab dov mus rau qhov ntsuas kawg thiab tsis softened tom qab. Nyob rau hauv lub xeev H18 nws nqa tag nrho cov strain hardening ntawm lub xeem dov dhau, uas muab nws siab zog thiab nruj, thiab nws tuav ib tug zaj duab xis ntawm dov lubricant ntawm ob qhov chaw tshwj tsis yog tias nws tau degreased. Cov roj residual tseem ceeb rau lub converter: luam ntawv number case, nplaum thiab txheej yuav tsis muaj kev ntseeg siab rau lub ntsej muag oiled, yog li ntawv tawv tawv yuav tsum tau degreased ua ntej luam ntawv, laminating lossis txheej. Qhov twg cov ntawv ci tsuas yog siv rau kev siv tshuab ua haujlwm, lossis qhov twg nws tau sib koom ua ke los ntawm cov txheej txheem uas ua rau cov roj nplua nyeem, nws tuaj yeem siv tau los ua cov dov. Vim nws yog tawv thiab springy, tawv ntawv tuav tuav flatness zoo thiab yog qhov kev xaiv ib txwm rau cov tais uas yog stamped es tsis kos.
Semi-Hard Foil
Semi-hard foil occupies cov qhab ntawm cov tawv thiab mos, feem ntau ua raws li H22, H24 los yog H26 los ntawm strain hardening nrog ib tug tswj ib nrab anneal. Nws lub zog yog qis dua H18 thiab nws qhov elongation siab dua, yog li nws deforms nyob rau hauv ib qho cuab yeej tsim tsis muaj cracking thaum tseem springing rov qab txaus los tuav ib tug tsim. Semi-hard foil yog qhov kev xaiv zoo rau cov thawv ntim khoom ib nrab, lub hau, cov tshuaj ntsiav thiab cov khoom ntim zoo li qhov yuav tsum khaws nws daim ntawv tom qab xovxwm tso tawm.
Soft Foil
Cov ntawv ci yog tag nrho annealed tom qab dov, uas muab tso rau hauv O temper. Nws yog lub xeev softest thiab feem ntau ductile, tsis muaj residual dov roj nyob rau saum npoo ib zaug annealed nyob rau hauv ib tug huv qhov chaw, thiab nws conforms rau qhov chaw nws yog qhwv ib ncig. Mos ntawv dominates ntim, lamination, rwb thaiv tsev thiab hluav taws xob daim ntaub ntawv, nrog rau lidding films, saj zawg zog laminates thiab cable qhwv. Nws lub zog qis tsis yog qhov tsis zoo hauv cov kev siv no, vim tias cov ntawv ci tau txais kev txhawb nqa los ntawm cov khoom siv polymer lossis cov ntawv nqa hauv cov laminate tiav.
| Xeev | Hom npau taws | Nto roj | Kev siv tseem ceeb |
|---|---|---|---|
| Nyuaj | H18 | Tam sim no tshwj tsis yog tias degreased | Stamped ntim, structural laminates, daim ntawv lo |
| Ib nrab tawv | H22, H24, H26 | Tsawg rau tsis muaj | Tsim, semi-rigid tais thiab hau |
| Mos | O | Tsis muaj | Ntim, laminating, rwb thaiv tsev, cable qhwv |
Nto Finish Classifications
Qhov thib ob axis ntawm kev faib tawm yog nto tiav. Ntawv ci dov nyob rau hauv cov pa ob pawg muaj ib sab matte, uas hu rau lwm lub vev xaib, thiab ib sab ci ntsa iab, uas tau hu rau polished ua haujlwm yob; qhov no yog piav raws li ib leeg-ci lossis ib leeg-matte ntawv ci. Cov ntawv ci rau cov hniav zoo nkauj zoo nkauj thiab luam ntawv feem ntau tau teev tseg tias ob lub ntsej muag ci, txhais tau tias ob lub ntsej muag ci, thiab matte lossis embossed tiav tau teev tseg qhov twg lub teeb yuav tsum raug txwv, piv txwv li hauv qee qhov hlwv thiab rwb thaiv tsev tsim. Nto tiav yog tswj los ntawm yob roughness thiab los ntawm lub sij hawm dov, thiab yog ib qho kev txiav txim cais los ntawm lub xeev ntawm cov ntawv ci.
Gauge Classification nyob rau hauv xyaum
Ordering xyaum ntxiv ib chav ntsuas ntsuas rau saum lub xeev thiab tiav. Lub ntsuas hnyav npog li ntawm 0.1 hli mus rau 0.2 hli, qhov ntsuas nruab nrab khiav los ntawm 0.04 hli mus rau 0.1 hli, thiab lub teeb ntsuas ntsuas npog txhua yam nyias nyias, suav nrog qhov ntsuas ob npaug ntawm 0.01 hli thiab hauv qab, qhov twg cov khoom siv feem ntau dov ob npaug thiab ua haujlwm nrog kev saib xyuas tshwj xeeb kom tsis txhob muaj wrinkles thiab pinholes. Tshuaj muaj pes tsawg leeg, thickness thiab mechanical khoom pov thawj rau cov ntawv ci raug txiav txim raws li qhov yuav tsum tau ntawm GB / T 3198 los yog EN 546-2, uas txhais tau hais tias cov tolerances thiab cov khoom vaj khoom tsev cov rooj siv thaum lub xeev tau xaiv.
Cov lus nug nquag
Q:Qhov txawv ntawm cov ntawv tawv tawv thiab cov ntawv mos yog dab tsi?
A: Cov ntawv tawv tawv yog dov thiab tsis yog annealed, yog li nws muaj zog, springy thiab nqa residual dov roj. Cov ntawv ci yog tag nrho annealed rau O temper, yog li nws yog ductile thiab tsis muaj roj.
Q:Puas nyuaj ntawv yuav tsum tau degreased?
A: Tsuas yog tias cov haujlwm hauv qab no yog luam ntawv, laminating lossis txheej, txhua yam xav tau qhov chaw huv. Yog tias cov ntawv ci yog siv los ua dov rau kev ua haujlwm, cov roj nplua nyeem tsis tas yuav muaj teeb meem.
Q:Thaum twg yog semi-hard foil xaiv txoj cai?
A: Thaum qhov yuav tsum tau tsim tsis muaj cracking tab sis yuav tsum tau ua kom nws cov duab tom qab tsim, uas yog cov yam ntxwv ntawm semi-rigid ntim, capsules thiab hau nyob rau hauv lub H22 mus rau H26 tempers.
Q:Ib qho ci ci ntawv txhais li cas?
A: Nws piav qhia txog cov ntawv ci dov nyob rau hauv ob pawg, qhov twg ib lub ntsej muag yog ci los ntawm polished yob thiab lwm yam yog matte los ntawm kev sib cuag nrog lub web ua ke. Ob chav ci ci muaj ob lub ntsej muag dov tawm tsam polished ua haujlwm yob.
Q:Dab tsi yog ob-zero foil?
A: Lub sij hawm ua lag luam rau cov chav ntsuas qhov sib sib zog nqus, feem ntau yog 0.01 hli thiab thinner, uas yog dov ob npaug thiab yuav tsum tau nruj dua yob-qhov sib txawv thiab kev tswj kom huv dua li cov ntsuas hnyav dua.
Q:Qhov twg yog foil tempers thiab tolerances txhais?
A: Temper designations ua raws li EN 515 lossis ANSI H35.1, thiab cov khoom thiab qhov ntev yuav tsum tau txiav txim rau EN 546-2 thiab EN 546-3 lossis rau GB / T 3198, nyob ntawm kev ua lag luam.
