Chithovu Chamkuwa

Chithovu chamkuwa ndi mtundu watsopano wazinthu zambiri zomwe zimakhala ndi mabowo ambiri olumikizidwa kapena osalumikizidwa omwe amagawidwa mofanana mu matrix amkuwa. Mkuwa thovu ali madutsidwe wabwino ndi ductility, ndi kukonzekera mtengo ndi wotsika kuposa faifi tambala thovu, ndi madutsidwe bwino, choncho angagwiritsidwe ntchito pokonza batire zoipa elekitirodi (chonyamulira) zipangizo, chothandizira zonyamulira ndi electromagnetic kutchinga zipangizo. Makamaka, thovu lamkuwa limagwiritsidwa ntchito m'mabatire monga gawo lapansi la elekitirodi, lili ndi zabwino zina zodziwikiratu, koma chifukwa cha kukana kwa dzimbiri zamkuwa sizili bwino ngati faifi tambala, motero zimalepheretsa zina mwazogwiritsa ntchito.

Njira yokonzekera

Chithovu cha polyurethane ngati gawo lapansi, pretreatment, mankhwala, electrodeposition ndi incineration ndi njira yochepetsera matenthedwe kuti akonzekere kugawa yunifolomu ya mawonekedwe atatu a mesh pore, chiŵerengero chachikulu chopanda kanthu (> 95%) ndi mphamvu inayake yamphamvu ya thovu lamkuwa. zakuthupi.

Electrolytic mkuwa ufa ndi NaCl particles monga zopangira, sintering ukadaulo wowononga pokonzekera kudzera-dzenje mkuwa thovu, ndi NaCl particles ndi electrolytic mkuwa ufa ndi zina zimasakanizidwa uniformly ndi mbamuikha kwa billet, mu sintering ng'anjo pansi mpweya mpweya. sintering, zinthu zopezedwa amayikidwa mu kuzungulira madzi otentha chipangizo adzakhala kusungunuka NaCl particles, ndiyeno akupanga madzi kusamba mu kutsuka ndi acetone kuyeretsa, ndipo potsiriza kuyanika, ndiko kuti, yokonza mkuwa thovu zipangizo ndi atatu azithunzi-thunzi olumikizana okhudza malo maukonde dongosolo ndi atatu azithunzi-thunzi olumikizana malo maukonde wapangidwa poyera pores, porosity wa 50~81 %. mankhwala.

Zida zamkuwa zamkuwa zokhala ndi makulidwe a yunifolomu, porosity yayikulu komanso mphamvu zina zolimba zimakonzedwa ndi preplating yamankhwala, electrodeposition ndi chithandizo cha kutentha.

Minda Yofunsira

Foam yamkuwa ndi mtundu watsopano wazinthu zogwirira ntchito zomwe zimagwiritsidwa ntchito kwambiri m'magawo otsatirawa.

1. Electrode zipangizo: conductivity kwambiri kuti thovu mkuwa akhoza ankagwiritsa ntchito mabatire faifi tambala-zinki, awiri wosanjikiza capacitors ndi zina latsopano batire electrode mafupa zipangizo, thovu mkuwa wakhala angapo faifi tambala-zinki batire opanga kuyesa ndi kuika mu mtanda. gwiritsani ntchito, panthawi imodzimodziyo, chithovu chamkuwa chikuyembekezeka kugwiritsidwa ntchito ngati chosonkhanitsa electrode electrode kwa ma capacitors awiri osanjikiza kuti apeze kutchuka ndi kugwiritsa ntchito; kuphatikiza apo, thovu lamkuwa lomwe limagwiritsidwa ntchito ngati electrolytic kuchira kwa zinthu zamkuwa zokhala ndi madzi otayira a elekitirodi, lilinso ndi chiyembekezo chotakata. Kuphatikiza apo, kugwiritsa ntchito thovu lamkuwa ngati zinthu za elekitirodi pakubwezeretsanso kwamadzi amkuwa okhala ndi mkuwa kulinso ndi chiyembekezo chotakata.

2. chothandizira: muzochitika zambiri zamakina achilengedwe, anthu amayesa kugwiritsa ntchito chithovu chamkuwa mwachindunji ndi malo akuluakulu m'malo mwa mkuwa wopangidwa ndi perforated, monga chothandizira kusintha kwamankhwala; thovu mkuwa monga photocatalytic mpweya kuyeretsa chonyamulira, wakhalanso ntchito bwino kwambiri.

3. Thermal conductivity zipangizo: mkuwa thovu ali kwambiri matenthedwe matenthedwe madutsidwe, kuupanga kukhala lawi retardant zipangizo ndi ntchito kwambiri, zipangizo zambiri zapamwamba moto m'mayiko akunja kupeza ntchito, makamaka ngati lawi kudzipatula zida ndi zotsatira zabwino; Komanso, anthu ntchito kwambiri matenthedwe madutsidwe thovu mkuwa ndi permeability zoonekeratu, opangidwa injini, zipangizo zamagetsi, kutentha dissipation zipangizo.

4. Kuphimba ndi kutchinga zipangizo: mafunde phokoso mumkuwa thovu pamwamba kufalitsa kusinkhasinkha, ndi kudzera kukulitsa kwa muffling, microporous muffling ndi mfundo zina, kukwaniritsa zotsatira za muffling; ntchito yotchinga yamkuwa ndi siliva pafupi ndi magwiridwe antchito a zida zotchingira zamagetsi.

5. Zosefera: zinthu zabwino kwambiri zomangika komanso zosavulaza thupi la munthu pazinthu zamkuwa zachitsulo, monga zida zosefera zamankhwala, zagwiritsidwanso ntchito bwino; nthawi yomweyo, mkuwa wa thovu mu chipangizo choyeretsera madzi umakhalanso ndi tsogolo labwino.

6. Kuthamanga kwamadzimadzi chobisalira zinthu: chithovu chamkuwa pa kubalalitsidwa kwamadzimadzi ndi buffer kwenikweni, kuti monga zida zosiyanasiyana zothamangitsira zida zochepetsera chitetezo, ndi zotsatira zabwino kwambiri.
