Dab tsi yog 8021 txhuas cov ntawv ci feem ntau siv rau?
8021 txhuas ntawv ci yog siv rau cov chaw muag tshuaj ntim khoom vim nws cov teeb meem zoo heev tiv thaiv ya raws, lub teeb, thiab cov pa oxygen. Nws tseem dav siv rau hauv cov khoom noj khoom haus rau cov khoom xws li chocolate, cov khoom noj siv mis, thiab cov tsiav tshuaj, thiab cov tshuaj tsw qab vim nws tsis muaj tshuaj lom. Lub duction alloy lub siab tso cai rau nws yuav tau dov rau hauv ultra-nyias ntawv (6-7μm) thaum tswj lub zog. Ib qho ntxiv, nws pabcuam ua cov khoom siv hau rau cov chav ua kua mis nyuj thiab sawv pob rau cov ntsiav tshuaj. Nws cov thermal conductivity ua rau nws haum rau kev siv hluav taws xob kub hauv kev lag luam ntim khoom.
Dab tsi yog qhov tseem ceeb tshuaj lom nta nta ntawm 8021 alloy?
Lub 8021 aluminium alloy muaj 98.5-99.3% txhuas nrog cov hlau tswj (0.8-1.2%) thiab silicon (tsawg dua lossis sib npaug nrog 0.6%) cov ntsiab lus. Qhov no tshwj xeeb muaj pes tsawg leeg tau txhim kho nws cov kev muaj thiab txo cov pinholes thaum lub sijhawm ci ntau lawm. Cov ntsiab lus tooj liab tsawg (<0.1%) ensures superior corrosion resistance compared to other alloys. Magnesium and manganese are kept below 0.05% to maintain softness and flexibility. These precise elemental ratios make 8021 ideal for deep drawing processes in packaging manufacturing.
Yuav ua li cas 8021 ntawv ci ua nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab?
8021 aluminium ntawv ci feem ntau ua rau lub zog tensile ntawm 80-120 mpa tom qab annealing. Nws elongation ntawm kev tawg ranges ntawm 15-25%, tso cai deformation ntau yam tsis muaj kev tawg. Cov ntawv sib xyaw ua cov kev ua tau zoo sib xws thoob plaws qhov kub ntawm -60℃rau 150 degree. Piv rau 8011 alloy, 8021 qhia tau zoo dua rau cov hlwv ntim. Cov khoom no nyob ruaj khov txawm tias tom qab ua tiav cov txheej txheem kom muaj zog xws li GAMMA irradiation lossis chav autoclaving.
Cov kev kho kom zoo li cas rau 8021 ntawv ci rau cov ntawv thov tshwj xeeb?
Kws Tshuaj 8021 ntawv ci feem ntau tau txais ib txoj kev kho Corona kom txhim kho luam tawm cov luam tawm cov ntawv nplaum. Cov zaub mov ntim khoom ntim cov ntawv yuav muaj cov tais diav hom tsiaj rau kev sib chwv nrog kev sib chwv nrog kev sib chwv nrog rau acidic cov ntsiab lus. Qee qhov sib txawv ua rau Anodization los tsim cov kab mob microporous rau kev siv khoom siv kev kho mob breathable. Cov ntawv ci saum npoo roughness (RA) yog qhov tseeb tswj nruab nrab ntawm 0.1-0.33μm rau kev ua yeeb yam zoo tshaj plaws. Cov kev kho mob tswj FDA / CE ua tiav thaum ntxiv cov khaubncaws sab nraud povtseg hauv qab 5μm tuab.
Vim li cas yog 8021 nyiam tshaj 1235 alloy rau qee cov ntawv thov ntim khoom?
8021 muaj cov pinhole zoo dua (tsawg dua los yog sib npaug / sib npaug / sib npaug / sib npaug / sib npaug ntawm nws cov ntsiab lus hlau. Nws cov recrystallization kub siab (300 Qib vs 250 degree) muab zoo dua tshiab thermal stability thaum lub sijhawm ntim ceev. Lub Alloy qhia meej txog 20-30% zoo dua formability nyob rau hauv tob-kos cov kab hlwv ntim cov ntawv thov. Rau cov tshuaj siv tshuaj siv tshuaj, 8021 qhia cov roj ntshauv tsis huv txhuas hauv cov tshuaj ua kua. Txawm li cas los xij, 1235 tseem nyiam dua rau cov ntawv thov ultra-siab heev uas tsis tshua muaj kev sib txuas yog qhov tseem ceeb.
