Thaum tshav kub kub Resistance thiab Anti-grease Performance: Tus cwj pwm ntawm 8011 Aluminium Ntawv Nyiaj hauv Bakeware thiab Tableware
1. Lub hauv paus rau phau ntawv
Nyob rau hauv niaj hnub khoom noj khoom haus-kev pab cuam thiab cookware kev lag luam, qhov kev thov rau cov khoom siv sib xyaw ua ke thermal stability, huv huv, thiab ib puag ncig sustainability txuas ntxiv mus. Ntawm tag nrho cov khoom siv hlau, 8011 aluminium ntawv ci sawv tawm rau nws lub peev xwm los tiv thaiv qhov kub thiab txias thaum muab kev tiv thaiv roj zoo dua thiab kev ua haujlwm tsis zoo. Cov yam ntxwv no ua rau nws indispensable nyob rau hauv manufacturing ntawm bakeware, cov tais zaub mov pov tseg, catering thawv, thiab tableware liners.
Kab lus no tshawb txog qhov thermal thiab anti-grease cwj pwm ntawm 8011 aluminium ntawv ci hauv bakeware thiab tableware, txheeb xyuas seb nws cov alloy muaj pes tsawg leeg, Nto Chemistry, thiab cov txheej txheem tsis ua rau muaj kev ua tau zoo. Nws kuj sib piv 8011 nrog cov khoom sib tw xws li stainless hlau, coated hlau, thiab polymer composites los ua kom pom nws qhov zoo ntawm engineering.
2. Thermal Resistance ntawm 8011 Aluminium Ntawv Nyiaj
2.1 Alloy Foundation rau Thaum tshav kub kub Resistance
8011 belongs rau 8xxx series ntawm txhuas alloys, nrog hlau (Fe) thiab silicon (Thiab) raws li thawj alloying ntsiab. Cov no tsim ib tug zoo intermetallic network uas txhawb cov txhuas matrix thiab ua rau kom kub-softening kuj. Tsis zoo li ntshiab 1050 los yog 1235 ntawv nyiaj, 8011 tuav txhua yam kev ncaj ncees txawm tias tom qab rov ua dua thermal cycling ntawm 250-350 ° C - qhov kub thiab txias ntau rau kev lag luam thiab tsev neeg ci.
2.2 Thermal conductivity thiab cua sov faib
Ib qho tshwj xeeb zoo ntawm aluminium ntawv ci hauv bakeware yog nws siab thermal conductivity, uas enables txawm cua sov faib thoob plaws qhov chaw ua noj. Cov alloy cov conductivity yog txo me ntsis piv rau cov ntshiab txhuas vim Fe-Si ntxiv tab sis tseem zoo dua rau feem ntau stainless hlau thiab ceramics..
| Lub rooj 1 - Thermal Properties Sib piv cov khoom siv Bakeware | |
|---|---|
| Khoom siv | Thermal conductivity (W/m·K) |
| 8011 Aluminium Ntawv Nyiaj | 230 - 240 |
| 1050 Aluminium Ntawv Nyiaj | 237 - 245 |
