Kev ua haujlwm zoo thermal yog ib qho tseem ceeb tshaj plaws uas txiav txim siab qhov zoo ntawm frypan. Hauv kev lag luam thiab kev tsim khoom noj khoom haus hauv tsev, cua sov tsis sib xws ua rau cov chaw kub kub, cov khoom noj scorched, warping, thiab kev puas tsuaj ntxov ntawm cov txheej tsis lo. Txhawm rau kov yeej cov teeb meem no, cov tuam txhab tsim khoom siv hluav taws xob cia siab rau lub voj voog aluminium (aluminium discs) kev koom ua ke rau hauv ntau lub ply clad bottoms lossis cuam tshuam-bonded encapsulated bases.
Los ntawm leveraging high-purity aluminium alloys raws li ib tug nyob rau hauv conductive core, clad frypans ua tau sai sai nqus cua sov thiab uniform ntug-rau-ntug tshav kub faib thoob plaws hauv qhov chaw ua noj.
Txheej txheem txheej txheem: Cladding Materials & Thermal Properties
Txawm hais tias stainless hlau muab cov qauv ua haujlwm ntev, induction compatibility, thiab tshuaj inertness, nws cov thermal conductivity kuj tsis zoo. Kev sib xyaw ua ke ntawm lub vaj huam sib luag aluminium core txuas qhov sib txawv ntawm qhov sib txawv ntawm cov hlau nplaum stainless hlau txheej txheej thiab cov khoom noj-hu rau qhov chaw ua noj.
| Khoom Txheej | Lub luag haujlwm tseem ceeb | Thermal conductivity (25 ∘C) | Tshwj xeeb kub muaj peev xwm |
| 1050/1060 Aluminium vajvoog | Thermal conduction Core | 229−234 W/m⋅K | 900 J/kg ⋅K |
| 3003 Aluminium vajvoog | Core Layer (Lub zog siab dua) | 160−190 W/m⋅K | 893 J/kg ⋅K |
| 430 (18/0) Stainless hlau | Txheej txheej (Induction Base) | ≈26 W/m⋅K | 460 J/kg ⋅K |
| 304 (18/8) Stainless hlau | Khoom noj khoom haus txheej txheej | ≈16 W/m⋅K | 500 J/kg⋅K |
1. Superior Thermal Conductivity tshem tawm cov chaw kub
Cov txheej txheem tseem ceeb tom qab multi-ply cladding yog thermal diffusivity. Ntshiab aluminium hloov kub ze li 15 npaug sai dua 304-qib stainless hlau.
Thaum tshav kub kub kis tau yooj yim: Thaum raug hluav taws xob hluav taws xob lossis hluav taws xob hluav taws xob, hluav taws xob hloov hluav taws xob los ntawm lub tshuab hluav taws xob mus rau hauv cov hlau nplaum sab nrauv hlau phaj thiab tam sim ntawd kis mus rau sab nraud ntawm lub voj voog aluminium.
Kub Spot Mitigation: Los ntawm dispersing thermal zog thoob plaws lub dav hlau kab rov tav ua ntej nws mus txog rau sab hauv ua noj ua haus nto, aluminium disc tiv thaiv high-temperature concentration ntsiab lus saum lub burner hais.
2. Kev Cia Siab Kub thiab Warping Resistance
Thaum ua noj, qhia cov zaub mov txias rau hauv lub lauj kaub kub ua rau qhov kub thiab txias hauv zos. Aluminium lub peev xwm tshwj xeeb kub kub (≈900 J / kg⋅K muab cov thermal inertia uas ua kom sov lub lauj kaub.
Impact Bonding & Cladding Integration: High-tonnage kev sib txhuam cladding presses los yog cov cav tov-bonding tshuab compress lub txhuas vaj huam sib luag (feem ntau yog 3.0 mm-6.0 mm tuab) ntawm cov nplooj ntawv sab hauv thiab sab nrauv ntawm qhov kub thiab txias.450℃-500 degree.
Structural Stability: Lub ductility ntawm annealed (O-temper) txhuas lub voj voog tso cai rau lawv deform me ntsis nyob rau hauv siab sib koom siab, sau micro-voids ntawm cov hlau txheej. Daim ntawv cog lus hlau txuas ntxiv no tiv thaiv thermal shock warping thaum lub sij hawm ceev ceev los yog ntxuav.
3. Kev xaiv Alloy rau Frypan Hauv qab Cladding
Xaiv qhov raug txhuas vaj huam sib luag alloy ncaj qha cuam tshuam rau cladding yield zog, kev sib raug zoo ntawm kev sib raug zoo, thiab thermal teb.
1050 / 1060 Aluminium Discs (Ntshiab Aluminium):
Conductivity: Qhov siab tshaj plaws thermal conductivity (Ntau dua lossis sib npaug rau 229 W / m⋅K).
Formability: High ductile nrog qis tawm los lub zog, tso cai rau cov khoom tshwj xeeb ntws thaum lub sij hawm muaj kev sib txuas siab. Qhov zoo tshaj plaws rau cov tuab tuab tuab (4 mm-8 mm).
3003 Aluminium Discs (Al-Mn Alloy):
Structural Strength: Siab zog txhua yam thiab dent kuj vim manganese ntxiv.
Thermal Balance: Ua kom muaj zog thermal conductivity (≈160-190 W / m⋅K) thaum muab kev nruj nruj rau lub cev 3-ply lossis 5-ply clad cookware.
4. Ntug-rau-ntug Thaum tshav kub kub hloov mus rau hauv lub cev puv-Ply Pans
Kev tsim kho cookware poob rau hauv ob pawg thawj: hauv qab-encapsulated bases thiab puv-lub cev multi-ply cladding.
Impact-Bonded Bottom Bases: Ib qho txhuas disc yog sib koom ua ke nkaus xwb rau sab nrauv sab hauv qab ntawm lub lauj kaub. Thaum tshav kub kub kis tau sai heev thoob plaws hauv qab, txawm tias thermal hloov mus rau ntsug sidewalls tseem txwv los ntawm lub hauv paus ciam teb.
Kev Siv Lub Cev Tag Nrho: Nruam roll-bonded 3-ply lossis 5-ply sheet hlau-sib txuas nrog lub voj voog txhuas hauv lub cev tag nrho- xa cov cua sov hloov mus rau sab phab ntsa. Qhov no ua kom muaj kev sib txig sib luag ntawm lub zog hluav taws xob thaum searing nqaij lossis txo cov kua ntses raws lub lauj kaub nkhaus.
Kev Tswj Xyuas Zoo rau Cladding-Qib Aluminium Vajvoog
Txhawm rau kom ntseeg tau tias tsis muaj qhov tsis zoo cladding thiab xoom delamination thaum lub sij hawm ntev siv cookware, raw cov voj voog yuav tsum ua raws li cov qauv hlau nruj:
Fine Grain Size Structure: Equiaxed grain qauv (ASTM 6 txog 8) los tiv thaiv nto roughness thaum tsim.
Flatness thiab Gauge kam rau ua: nruj thickness kam rau ua (± 0.02 hli) los lav txawm tias kub dispersion thiab uniform cladding siab.
Oil-Free Deg Cleanliness: Ua tiav tshem tawm cov roj dov thiab cov kab mob ntawm qhov chaw kom ua tiav qhov siab tshaj plaws ntawm cov hlau nplaum lub zog thaum lub sij hawm muaj kev kub ntxhov.
Xaus
Txhuas lub voj voog txhim kho cov cua sov hauv qab hauv qab cladding los ntawm kev ua raws li kev kub ceev thermal faib txheej ntawm cov txheej txheem txheej hlau. Los ntawm kev xaiv high-purity 1050, 1060, los yog 3003 txhuas discs nrog optimized grain qauv thiab meej thickness tolerances, cookware manufacturers tshem tawm kub me ntsis, txhim kho lub zog efficiency, thiab tiv thaiv thermal warping nyob rau hauv hwm clad pans.
