Haɗin kayan aluminum na kayan kwalliya na kitchenware: Tabbatarwa Tsarin Tsallaka da Tabbatarwa na Aiwatarwa don kawar da kumfa da maraice

1. Shigowa da

Haɗin fayafai na aluminum don kayan dafa abinci su ne core substrates for high-end cookware (e.g., Ba a sanda ba soya, bakin karfe-lafumi miya, da kuma abubuwan shigowa-mai jituwa), suna buƙatar manyan wasanni uku marasa sasantawa don biyan buƙatun dafa abinci na yau da kullun:

1. Thermal conductivity uniformity: Matsakaicin zafin jiki a saman fayafai dole ne ya zama ≤5% don guje wa zafi na gida (e.g., ƙona gefuna kwai a cikin kwanon frying) - ana samun wannan ta hanyar waje 3003 gami, wanda ke da wutar lantarki na 200W /(MİI K), 30% sama da tsantsa aluminum;

2. Ƙarfin tsari: Ƙarfin Haɓaka ≥180MPa don tsayayya da nakasawa yayin yin hatimi (e.g., kafa tukunyar miya mai zurfin cm 10) da kuma amfani da dogon lokaci - tsakiya 5052 gami (jerin Al-Mg) yana ba da wannan ƙarfi, tare da abun ciki na Mg 2.5% inganta lalata juriya (m ga acidic abinci kamar tumatir);

3. Thermal girgiza juriya: Babu fashewa bayan 20+ hawan keke tsakanin -20 ℃ (ajiya mai firiji) da 260 ℃ (yin burodin tanda) - babban abin da ake buƙata don kayan dafa abinci waɗanda ke canzawa tsakanin ajiyar sanyi da dumama murhu.

Tsarin haɗe-haɗe na yau da kullun shine 3003/5052/3003, tare da diamita jere daga 100mm (kananan kwanon rufi) ku 300mm (manyan woks) kuma jimlar kauri na 3-8mm (kauri ga tukwane miya, bakin ciki don frying pans).

Muhimmiyar ƙulli mai inganci shine lahani interlayer: Kumfa masu diamita ≥0.5mm suna haifar da dumama mara daidaituwa (bambancin zafin jiki har zuwa 50 ℃), yayin da delamination take kaiwa zuwa ga nakasawa cookware ko ma detachment na mara sanda shafi. Bisa lafazin 2024 bayanai daga China Kitchenware Association, 32% na kumshin diski na aluminium ya samo asali ne daga batutuwan interlayer, tare da matsakaicin asarar juzu'i guda ≥800,000 yuan (e.g., 5,000 yanki na fayafai na kwanon rufi 24cm saboda kumfa).

Hanyoyin mirgina na gargajiya sun kasa magance waɗannan lahani saboda rashin daidaiton sigogi (e.g., rashin isasshen zafin jiki don yaduwar atomic, matsatsi mara daidaituwa yana barin aljihun iska). Don haka, daidaitaccen sarrafa zafin jiki na mirgina, matsa lamba, kuma raguwa yana da mahimmanci don cimmawa “sifili interlayer kumfa da delamination”.

2. Dalilan Matsalolin Interlayer

Lalacewar interlayer sun taso daga haɗe-haɗen tasirin abubuwan da ke tattare da abubuwan da ke tattare da su da haɓakar tsari, tare da bayyanannun hanyoyin kowane:

(1) Abubuwan da ke da alaƙa da Material

The 3003 kuma 5052 Alloys a cikin fayafai masu haɗaka suna da bambance-bambancen kaddarorin da ke hana haɗin haɗin yanar gizo, kamar yadda aka dakile a cikin tebur da ke ƙasa:

(2) Abubuwan da ke da alaƙa da tsari

Ko da tare da kayan da aka dace da kyau, sigogin mirgina mara kyau suna haifar da lahani kai tsaye:

• Rashin daidaituwar yanayin zafi:

• • Kasa da 380 ℃: Ƙarfin motsin atom ɗin ya yi ƙasa da ƙasa - Mg atom a ciki 5052 iya yada 0.1-0.2μm kawai, kasa haye Layer oxide. Wannan ya fita “jiki lamba gibin” (5-10μm) tsakanin yadudduka, wanda ke kama iska da kuma samar da kumfa.

• • Sama da 500 ℃: Mn in 3003 yana hazo kamar yadda Al₆Mn hard particles (1-3μm), wanda ya karu da 5052 Layer a lokacin mirgina. high zafin jiki accelerates hadawan abu da iskar shaka, kauri daga Al₂O₃ Layer zuwa >10nm, daɗaɗa haɗin kai.

• Matsalolin matsin lamba:

• • Kasa da 10MPa: Rashin isasshen ƙarfi don fitar da iska mai tsaka-tsaki (farkon kauri 5-10μm). Iskar da aka matse ta haifar da kumfa (0.3-1mm diamita), kuma wurin tuntuɓar mu'amala kawai 60-70%, haifar da rauni bonding.

• • Karɓar matsi >5MPa: Saboda rashin daidaituwar damuwa na mirgine, gefen diski (babban matsin lamba) Karfe ya cika, yayin da cibiyar (ƙananan matsa lamba) yana riƙe da iska - lahani na kowa a cikin fayafai masu girman diamita (≥250mm).

• Ragi mara ma'ana:

• • Jimlar raguwar adadin <40%: Ƙarfe nakasar bai wadatar ba don daidaita kuskuren mu'amala (3-5μm), barin ƙananan kumfa waɗanda ke faɗaɗa lokacin dumama girki.

• • Ƙimar rage-wuri ɗaya >30%: Karfe yana gudana da sauri (>100mm/s), entraining iska a cikin dubawa. Matsanancin nakasawa kuma yana haifarwa “garkuwar karfi” (1-2μm) tsakanin yadudduka, wanda ke tasowa zuwa delamination bayan sanyaya.

3. Dabarun Dokokin Haɗin kai

Don magance dalilan da ke sama, an ɓullo da dabarun haɗin gwiwa don 3003/5052/3003 hadadden fayafai (girman φ200mm, manufa kauri 6mm a matsayin misali), mai da hankali kan “zafin jiki a matsayin tushe, matsa lamba a matsayin maɓalli, da kuma raguwa a matsayin garanti”.

• • Sakamako: Ƙirƙirar ƙimar cancanta ya ƙaru daga 78% (gargajiya, lahani: fatashin, delamination) ku 99% (ingantacce, babu lahani).

6. Shari'ar Aikace-aikacen Masana'antu

Babban kamfani na kayan dafa abinci na kasar Sin (fitarwa na shekara-shekara: 10 miliyon sets, manyan kayayyakin: kwanon rufin da ba sanda ba) sun fuskanci matsaloli masu inganci a ciki 2023:

• Al'amari: 8.5% na frying pans an tuna saboda interlayer kumfa (korafe-korafen abokin ciniki: “abinci yana konewa gefe guda”); rukuni guda na 5,000 An goge fayafai φ24cm, yana haifar da rufe layin samarwa na kwanaki 2 da 1.2 yuan miliyan a cikin hasara.

• Matakan ingantawa: An karɓi dabarun haɗin gwiwa a sama, ciki har da:

1. 1. Daidaita preheating zafin jiki daga 390 ℃ zuwa 430 ℃, Tsawaita lokacin riƙewa zuwa 35min;

1. 2. Shigar da tsarin hydraulic zoned (matsin lamba + 4MPa) don warware kumfa na tsakiya;

1. 3. Aiwatar da 1200-grit polishing da ƙananan zafin jiki annealing (290℃, 2.5h);

1. 4. Amfani da Rolls masu rufin CrN (ku 0.08m) don rage lahani na ciki.

• Sakamako:

7. Ƙarshe & Outlook

(1) Core ƙarshe

Mabuɗin cimmawa “sifili interlayer kumfa da delamination” domin hadadden fayafai na aluminum don kayan dafa abinci yana ciki Gudanar da haɗin kai na sigogi masu mahimmanci guda uku (ƙarfin zafi, matsa lamba, raguwar adadin) da matakan taimako:

• Zazzabi: 420-450℃ preheating + 400-430℃ m rolling + 380-400℃ gama mirgina - yana tabbatar da isasshen atomic diffusion yayin guje wa iskar shaka da hazo;

• Matsi: 15-20MPa zone matsa lamba (gefen + 3-5MPa) - gaba daya korar interlayer iska da kuma tabbatar da uniform lamba;

• Yawan raguwa: 50%-60% jimlar kudi + 16.7%-30% Rarraba gradient guda-wuri - ma'auni na lalacewa da damuwa;

• Hanyoyin taimako: Ragewa + goge baki + inert gas kariya + annealing - yana kawar da ɓoyayyun lahani kuma yana daidaita haɗin gwiwa.

Wannan haɗin yana samun ƙarfin haɗin gwiwa ≥18MPa, Yawan kumfa ≤0.1%, kuma ya cika duk buƙatun aikin kayan dafa abinci.

(2) Hannun Ci gaban Gaba

1. Tsarin siga mai hankali:

• • Ƙirƙirar samfurin hanyar sadarwa na BP wanda ke shigar da bayanan ainihin lokaci (ƙarfin zafi, matsa lamba, mirgine gudun) kuma yana fitar da yiwuwar lahani. Lokacin da yuwuwar ta wuce 5%, tsarin yana daidaita sigogi ta atomatik (e.g., yana ƙara ƙarfin dumama shigar idan zafin jiki ya faɗi, ko daidaita matsa lamba na hydraulic idan an gano kumfa ta hanyar firikwensin ultrasonic). Wannan zai rage dogaro ga aikin hannu da inganta tsarin aiki zuwa >99%.

2. Sabbin tsarin haɗin kai:

• • Don kayan dafa abinci masu nauyi (e.g., tukwane zangon waje), bunkasa 3003/6061/3003 hadadden fayafai (tsakiyar Layer 6061 gami: Ƙarfin yawan amfanin ƙasa ≥270MPa). Siffofin da aka keɓance: preheating zafin jiki 450-480 ℃ (yayi daidai da 6061's recrystalization zafin jiki), mirgina matsa lamba 20-25MPa (rama ga mafi girma ƙarfi), da ragin fasfo ɗaya ≤25% (yana guje wa fashewa).

3. Hanyoyin da suka dace da muhalli:

• • Sauya gurɓataccen alkaline na gargajiya tare da lalata tushen ruwa na ultrasonic (yana rage amfani da sinadarai ta hanyar 50%) da kuma samar da man da za a iya sake yin amfani da su (Yawan sake yin amfani da su ≥80%) don cika ka'idojin muhalli na duniya (e.g., NA KASANCE).

Haɓakawa na tsarin jujjuyawar diski na aluminium ba wai kawai yana haɓaka ingancin kayan dafa abinci da rage farashi ba har ma yana ba da ma'anar fasaha don sauran kayan ƙarfe da aka haɗa. (e.g., aluminum-Copper, aluminum-karfe), tuki bidi'a a cikin sauki karfe sarrafa masana'antu.
