Yog vim li cas Aluminium Yog Cov Hlau Hlau ntawm Niaj Hnub No Cookware
Aluminium yog cov hlau ua haujlwm ntawm chav ua noj vim tias nws ua ke peb lub zog uas tsis muaj lwm yam qis - nqi hlau muab tib lub sijhawm: tsawg ntom, siab thermal conductivity thiab zoo formability. Nrog rau qhov ntom ntom ntawm 2.70 g / cm³, 3 hli aluminium yias lub cev hnyav li ib feem peb ntawm qhov sib npaug ntawm lub cev stainless hlau, uas tseem ceeb rau kev tuav, lub hau haum thiab qhov ceev ntawm lub lauj kaub teb rau qhov hloov pauv. Thermal conductivity ntawm kev lag luam purity thiab 3xxx qib nyob ntawm 180 thiab 237 W / m·K, yog li cov cua sov kis thoob plaws hauv lub hauv paus hauv vib nas this thiab qhov chaw kub hauv qab cov nplaim hluav taws yog smoothed tawm ua ntej nws tuaj yeem hlawv cov zaub mov.
Formability tso cai rau sib sib zog nqus nqus lub cev, spun rims, stamped leeg thiab dov npoo yuav tsum tau ua los ntawm ib tug coil los yog lub voj voog dawb paug. Qhov ntawd ua rau cov cuab yeej siv qis thiab ua kom cov phab ntsa tuab zoo ib yam los ntawm batch mus rau batch, uas yog qhov nyuaj thaum ntau qhov sib cais yuav tsum tau koom nrog.
Qib thiab Tempers siv rau Cookware thiab Utensils
Feem ntau cookware yog tsim los ntawm ib tsev neeg me ntawm wrought alloys. Kev xaiv yog tsav los ntawm drawability, thermal conductivity thiab nqi es tsis yog los ntawm lub zog siab tshaj plaws.
| Alloy thiab tempered | Kev siv cov khoom siv hluav taws xob | Tensile zog | Yam ntxwv tseem ceeb |
|---|---|---|---|
| 1050 / 1060 H14 | Clad cores, liners | 100-145 MPa | Siab tshaj conductivity, softest |
| 3003 H14 | Pans, pots, bakeware | 150 MPa | Qhov zoo tshaj plaws sib npaug ntawm kos thiab tus nqi |
| 3004 H24 | Kos lub cev xav tau kev nruj | 200 MPa | Siab zog, nruab nrab kos |
| 5052 H32 | Cov khoom siv, cov khoom siv, cov chaw pw hav zoov | 228 MPa rau | Qhov zoo tshaj plaws corrosion kuj |
| 6061 T6 | Handles, rivets, hau, brackets | 310 MPa | Muaj zog thiab anodizes huv si |
Multi-ply kev tsim kho daim ntawv cog lus nyias 1050 lossis 3003 core ntawm stainless hlau ntsej muag kom lub ntsej muag ua noj nyob qis qis thaum lub hauv paus tseem kis tau cua sov. Rau cov khoom lag luam cov tub ntxhais txhuas feem ntau yog muab los ua cov kauj hauv H14 lossis H24 temper nrog nruj tuab kam rau ua thiab tswj kev tiaj tus kom cov yob - cov kab sib txuas khiav tsis muaj ntug tawg.
Anodized thiab coated tiav
Anodizing hloov lub ntuj 2-4 nm oxide zaj duab xis rau hauv qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Hom II sulfuric anodizing tsim 5-25 µm ntawm oxide, thaum Hom III nyuaj anodizing tsim 25-50 µm nrog ib tug deg hardness nyob rau hauv thaj tsam ntawm 400-500 HV, piv rau hardened steel thiab deb harder tshaj cov hlau hauv qab. Anodized nto yog li ntawd tiv thaiv khawb los ntawm cov hlau spatulas thiab txo cov kev hloov ntawm txhuas rau hauv cov khoom noj acidic.
Tsis yog - cov tshuab nplaum yog siv rau saum txheej oxide. Sintered PTFE coatings muab qhov qis tshaj tawm, thaum ceramic sol-gel coatings pauv qee qhov kev tso tawm rau kev khawb siab dua thiab kam rau cov khoom siv hlau. Nyob rau hauv txhua rooj plaub txheej kev ua tau zoo nyob ntawm ua ntej- kev kho mob: txheej txheej etched los yog anodized yog dab tsi ua rau cov txheej txheem sib txuas los ntawm kev rov ua dua thermal cycling thiab lub tshuab ntxuav tais diav.
Kev nyab xeeb, acidic zaub mov thiab hloov hlau
Tsis kho cov txhuas ua rau tus kheej- rov ua dua oxide txheej uas txwv tsis pub cov tshuaj tiv thaiv nrog zaub mov. Cov khoom xyaw acidic xws li txiv lws suav, vinegar, cawv thiab citrus ua kom nrawm nrawm, thiab cov hlau xa mus nce nrog lub sijhawm ua noj, kub thiab ntsev cov ntsiab lus. Cov tswv yim tswj tau nkag siab zoo: ua cov tais diav acidic hauv anodized, coated los yog multi-ply cookware, tsis txhob khaws cov khoom noj acidic nyob rau hauv liab qab aluminium thaum hmo ntuj, thiab tsis txhob siv liab qab txhuas rau ntev simmering ntawm salted sauces.
Cov tub ceev xwm saib xyuas kev noj qab haus huv kho qhov teeb meem yog ib qho ntawm tag nrho cov kev noj zaub mov tsis yog ntawm cookware ib leeg. Lub Koom Haum Koom Tes FAO / WHO Cov Kws Tshaj Lij Tshaj Lij rau Cov Khoom Noj Ntxiv tau teeb tsa ib lub lim tiam kom tau txais 2 mg ntawm txhuas rau ib kg ntawm lub cev qhov hnyav, thiab cov cai tswj kev noj zaub mov hauv ntau lub khw siv ib qho kev txwv kev tsiv teb tsaws ntawm 5 mg ib kg ntawm zaub mov. Kev ua noj ua haus hauv suab nrov aluminium cookware pab txhawb ib feem me me ntawm daim duab ntawd, thaum cov lauj kaub thiab cov pitted thiab cov kua qaub sib txuas ntev ua rau muaj txiaj ntsig ntau dua.
Ob txoj cai ntxiv tshem tawm feem ntau qhov kev pheej hmoo. Ua ntej, aluminium cookware yuav tsum tsis txhob siv rau qhov sib sib zog nqus - kib ntawm qhov kub thiab txias yam tsis muaj txheej txheej, vim tias daim ntawv nyias nyias tuaj yeem cuam tshuam. Qhov thib ob, tsis txhob siv cov txhuas uas tsis muaj coated nrog cov tshuaj alkaline uas muaj zog heev los yog nrog cov tshuaj ntxuav tais diav, vim tias alkaline nres dulls thiab darkens qhov chaw nrawm dua li cov khoom noj.
Kev tu, tu thiab kev pab lub neej
Kev ntxuav tes nrog xab npum me me thiab daim txhuam cev mos khaws cia ob qho tib si oxide txheej thiab txhua txheej txheej. Hlau ntaub plaub thiab txhoj puab heev scouring hmoov tawg los ntawm txheej anodized thiab nthuav tawm cov hlau tshiab, uas tom qab ntawd darkens thiab reacts sai dua. Baking soda paste lifts burnt residue without abrasion, and a dilute vinegar rinse tshem tawm cov dej me ntsis tab sis yuav tsum tau ua raws li cov dej huv huv vim tias vinegar nws tus kheej tawm tsam liab qab. Qhuav lub lauj kaub kom qhuav ua ntej khaws cia, khaws cia kom deb ntawm cov thawv ntim khoom ntub dej thiab tsis txhob muab cov lauj kaub uas tsis muaj coated uas tsis muaj cov kab tiv thaiv. Aluminium uas tau raug anodized tuaj yeem rov ua dua- ntxuav ntau zaus yam tsis tau poob nws cov txheej txheem tiv thaiv, vim tias cov oxide loj hlob rau hauv cov hlau es tsis siv rau saum nws.
Nrog rau kev siv tau zoo, lub cev lub cev muaj zog anodized tseem tuaj yeem siv tau ntau xyoo. Txawm tias lub lauj kaub puas ua rau nws tus nqi: aluminium remelts ntawm ib feem me me ntawm lub zog xav tau los tsim cov hlau tseem ceeb thiab khaws nws cov khoom, yog li cov khoom siv khib nyiab yog qib siab - qib feedstock rau cov smelters theem nrab.
Cov lus nug nquag
Q: Puas yog aluminium cookware muaj kev nyab xeeb rau kev ua noj txhua hnub?
Yog rau ib txwm ua noj. Lub ntuj oxide txheej txwv cov tshuaj tiv thaiv nrog zaub mov; kev pheej hmoo tsuas yog nrog kev sib cuag ntev ntawm cov kua qaub los yog cov khoom noj ntsev hnyav thiab cov hlau liab qab, thiab cov npoo anodized los yog coated txo kev hloov mus ntxiv.
Q: Dab tsi alloy yuav tsum tau teev tseg rau ib lub cev yias stamped?
3003 H14 npog feem ntau stamped thiab kos lub cev. Xaiv 3004 H24 thaum lub cev xav tau ntau zog, thiab 5052 H32 thaum corrosion kuj thiab lub zog tseem ceeb tshaj thermal conductivity.
Q: Vim li cas anodized cookware raug nqi ntau dua li tsis muaj txhuas?
Anodizing ntxiv ib txoj kab electrochemical, thicker oxide kev loj hlob thiab nruj dua ua ntej - tswj kev kho mob. Cov txiaj ntsig yog qhov nyuaj, tsis tshua muaj reactive nto uas xav tau tsis muaj seasoning thiab zam cov khoom siv hlau zoo dua.
Q: Yuav ua li cas tuab daim ntawv cookware?
Feem ntau lub cev khiav 2.0-3.5 hli, bakeware 1.0-2.0 hli thiab cov tais diav 0.8-1.5 hli. Thicker daim ntawv kis tau cua sov ntau tusyees tab sis nce qhov hnyav, tsim cov khoom thauj thiab cov nqi khoom.
Q: Cov khoom siv txhuas puas tuaj yeem siv rau ntawm qhov cub induction?
Tsis ncaj. Induction yuav tsum muaj lub hauv paus ferromagnetic, yog li induction-paj npaj siv ntau-ply tsim nrog stainless hlau txheej txheej los yog sib nqus sib nqus disc ntawm lub hauv paus.
Q: Puas yog aluminium cookware hnav?
Bare aluminium thins maj mam nyob qhov twg nws yog scoured, thiab coatings nws thiaj li npub. Warping los ntawm thermal shock thiab tuav qaug zog yog qhov kawg ntawm lub neej, tsis poob ntawm cov hlau nws tus kheej.
