Cov ntawv ci roj teeb yog cov ntawv txhuas siv los ua ntau yam haujlwm rau cov roj teeb, thaum cov ntawv ci hluav taws xob yog cov ntawv txhuas siv los ua ntau yam haujlwm rau lwm yam khoom siv hluav taws xob. Lawv kuj tuaj yeem raug hu ua cov ntawv ci hluav taws xob. Roj teeb ntawv ci yog cov khoom siv high-tech nrog kev loj hlob txhua xyoo ntawm ntau dua 15% hauv ob peb xyoos tom ntej. Cov khoom siv hluav taws xob ntawm cov ntawv nyiaj cable thiab cov ntawv roj teeb tau pom nyob rau hauv Table 3 thiab Table 4. 2019-2022 yog lub sijhawm ntawm kev loj hlob zoo rau cov tuam txhab roj teeb hauv Suav teb. Muaj kwv yees li 200 lub tuam txhab uas tau muab tso rau hauv kev tsim khoom lossis kev tsim kho, nrog rau tag nrho cov peev txheej ntawm 1.5 lab tons.
Electrolytic capacitor aluminium foil yog qhov ua tiav cov khoom sib sib zog nqus. Nws yog cov khoom siv corrosive uas ua haujlwm nyob rau hauv polar tej yam kev mob thiab muaj kev xav tau siab ntawm cov qauv ntawm cov ntawv ci. Muaj peb hom aluminium ntawv ci siv: cathode ntawv ci nrog lub thickness ntawm 0 015-0 06mm, high-voltage anode ntawv ci nrog lub thickness ntawm 0. {6}}.1mm, thiab aluminium ntawv ci nrog lub thickness ntawm 0 065-0.1mm. 0.06-0.1mm low voltage anode ntawv ci. Cov ntawv ci anode yog ua los ntawm cov khoom siv high-purity aluminium, thiab cov feem ntau yuav tsum ntau dua los yog sib npaug rau 99.93%, thaum lub purity ntawm txhuas siv nyob rau hauv high-voltage anodes yuav tsum ntau dua los yog sib npaug rau 4N. Lub ntsiab impurities ntawm kev lag luam high-purity txhuas yog Fe, Si, thiab Cu, thiab kab kawm Mg, Zn, Mn, Ni, thiab Ti yuav tsum tau kho raws li impurities. Suav cov qauv tsuas yog teev cov ntsiab lus ntawm Fe, Si, thiab Cu, tab sis tsis qhia meej cov ntsiab lus ntawm lwm cov ntsiab lus. Cov ntsiab lus impurity ntawm txawv teb chaws roj teeb txhuas ntawv ci yog qhov qis dua li ntawm cov khoom siv hauv tsev.
Raws li GB/T8005.1, aluminium ntawv ci nrog lub thickness tsis tsawg dua 0.{14}01mm thiab tsawg dua {{21} }.01mm yog hu ua ob-zero foil. Feem ntau siv alloys yog 1145, 1235, 1350, thiab lwm yam. Cov alloys feem ntau siv yog 1235, thiab nws cov Fe/Si piv yog 2.5 -4.0. Aluminium ntawv ci nrog lub thickness tsis tsawg tshaj li 0.01mm thiab tsawg dua 0.10mm yog hu ua ib leeg-zero foil. Capacitors feem ntau siv 1235-H18 (0.020-0.050mm tuab); Lub xov tooj ntawm tes roj teeb siv 1145-H18 thiab 8011-H18, uas yog 0.013-0.018mm tuab; Cov ntawv siv cable siv yog 1235-O, nrog lub thickness ntawm 0.010-0.070mm. Ntawv ci nrog lub thickness ntawm 0.10-0.20mm yog hu ua xoom-dawb ntawv ci. Cov khoom tseem ceeb yog cov ntawv ci zoo nkauj, cov ntawv ci cua txias, cov ntawv ci cable, cov ntawv ci lub raj mis, thiab cov ntawv ci kaw.
