1. Kwitegura
Kugirango byorohereze ikizamini cya electrochecher electrochecher, 30mm cyatoranijwe × 4 mm 304 ibyuma bidafite ishingiro nkibishingiro. Polonye kandi ukureho ibice bya okiside isigaye hamwe nibimenyetso bifatika hejuru yisumbuye hamwe na sandpaper, ubishyire mubice biri hejuru yisosiyete ya bargjie electronics kuri 20min, Kuraho Kwambara imyanda hejuru yicyuma hamwe ninzoga n'amazi yatoboye, akayumisha hamwe na blower. Noneho, alumina (al2o3), Gweri na Hybrid Carbone Nanotube (Mwnt-Coohsdbs) yateguwe mubyiciro (100: 0.2: 9.2: 0.2: 0.2: 0.2: 0.2: 0.2: Kuri Urusyo rwa ball (QM-3P2 rwigikoresho cya Nanjing Nanda) kugirango bahishe ball kandi bavange. Umuvuduko uzunguruka ku ruganda rw'umupira rwashyizwe ku ya 220 r / min, kandi uruganda rwa barall rwahindutse
Nyuma yo gusya umupira, shiraho umuvuduko wo kuzunguruka wumupira wo gusya umupira kugirango ube 1/2 ubundi buryo nyuma yo kuzunguruka umupira wo gusya umupira kugirango babe 1/2 ubundi buryo nyuma yo gusya umupira urangiye. Umupira utangaje ceramic igiteranyo kandi bitandukanijwe bivanze ukurikije ibice rusange bya 1.0: 0.8. Amaherezo, ipfundo ry'i Ceramic ryabonetse no gukiza.
2. Ikizamini cya ruswa
Muri ubu bushakashatsi, ikizamini cya electrochemical ikizamini cya shanghai chenhua chi660e ikorera rya electrochemike, kandi ikizamini cyerekana sisitemu yikizamini cya electrode eshatu. Platine electrode ni electrode yafashanye, ifeza ya feza ya feza ni electrode, hamwe nijwi ryapa nizo electrode ikora, hamwe nuburyo bwiza bwo kwerekana 1cm2. Huza ibya electrode, gukora electrode na electrode ya electrolytic muri selile, nkuko bigaragara ku gikoresho cya 1 na 2. Mbere yikizamini, shyiramo icyitegererezo muri electrolyte, nicyo gisubizo cya NaCl.
3. Isesengura rya Tafel rya ruswa rya electrochemique yo gukopera
Igishushanyo cya 3 cyerekana umurongo wa tafel wo gusohora hejuru kandi ceramic yashizwemo na NANO zitandukanye nyuma ya electrochemical kuri 19h. Iltision Voltage, ruswa yuzuye hamwe namakuru yikizamini cyamashanyarazi yabonetse mubizamini bya electrochemical byerekanwe mu mbonerahamwe ya 1.
Tanga
Iyo ubucucike bwubu buke buke kandi bukarwanya ruswa ni bwo hejuru, ingaruka zo kurwanya ruswa zo guhinga ni nziza. Irashobora kugaragara kuva ku gishushanyo cya 3 n'imbonerahamwe 1 ko igihe umwanya wa ruswa ari 19h, umuvuduko mwinshi wa matrix na we, hamwe na ruswa muri Matrix nazo nini, kugera kuri 2.890 a / CM2. Iyo yashizwemo hamwe na alumina ceramic, ubucucike bwa none bwagabanutse kugera kuri 78% na pe byari 22.01%. Irerekana ko ipati yo gukingirwa ceramic igira uruhare ruririnda kandi irashobora kunoza indwara yo kurwanya ruswa muri electrolyte idafite aho ibogamiye.
Iyo 0.2% Mwnt-Cooh-SDB cyangwa 0.2% yongerewe ku ishyaka, ubucucike bwa ruswa bwagabanutse, hamwe no kurwanya ruswa Iyo ubuso butwikiriwe na 0.2% MWNT-Cooh-SDBs na 0.2% bivanga kwa Alumina, birambuye byagabanutse guhera 2,890 × 10-6 a / cm2, kurwanya ntarengwa Agaciro, wiyongereye kuva 11388 ω kugeza 28079 ω, kandi per of coating irashobora kugera kuri 46.85%. Irerekana ko ibicuruzwa byateguwe bifite imbaraga zo kurwanya ruswa, kandi ingaruka za synorgistic za karubone nanotubes naho Grayhene irashobora kunoza neza ihohoterwa rya ruswa.
4. Ingaruka zo Kugenda Igihe cyo Guhangana Impetance
Kugirango ushobore gushakishwa no kurwanya ruswa, urebye ingaruka zo kwibiza mugihe cyicyitegererezo muri electrolyte mugihe cyo kwipimisha ibintu bine mubibazo bitandukanye biboneka, nkuko bigaragara ku gishushanyo 4.
Tanga
Mugihe cyambere cyo kwibizwa (10 h), kubera ubwinshi n'imiterere yimyenda, electrolyte iragoye kwibiza mu ipfundo. Muri iki gihe, indege ya ceramic yerekana kurwanya cyane. Nyuma yigihe runaka, imyigaragambyo igabanywa cyane, kuko igihe cyagenwe, electrolyte buhoro buhoro ikora umuyoboro wa ruswa kandi ucikamo ibice kandi binjira muburyo bugaragara mu kurwanya IHURIRO.
Mu cyiciro cya kabiri, mugihe ibicuruzwa bya ruswa byiyongera kumafaranga runaka, diffsion irahagarikwa kandi icyuho kirahagarara buhoro buhoro. Muri icyo gihe, iyo electrolyte yinjiye mu ntera yo guhuza igice cyo hasi / matrix y'amazi izakirana na fene muri matrix kuri matrix of the film yoroheje, ibangamira Kwinjira kwa electrolyte muri matrix kandi byongera agaciro kirwanya. Iyo ibyuma byambaye ubusa ari ingwate za electrochemike, ibyinshi byimvura yicyatsi kibisi yakozwe munsi ya electrolyte. Igisubizo cya electrolytic ntabwo cyahinduye ibara mugihe electrolyzing icyitegererezo cyapakiwe, kirashobora kwerekana ko hariho imiti yavuzwe haruguru.
Bitewe nigihe gito cyo kugenda hamwe nibintu binini byo hanze, kugirango ugaragaze neza umubano mwiza wa electrochemical ibipimo bya electrochemical, umurongo wa tafel wo mu 19 h na 19.5 H barasesenguwe. Ibicuruzwa byuzuye hamwe no kurwanywa byabonetse na ZSIMPWIn isesengura rya porogaramu ya ZSIMPWWIN yerekanwa mu mbonerahamwe ya 2. Urashobora kuboneka hamwe na bambaye ubusa, ugereranije no guhimba kwambukiranya imyaka 19 Gitoya kandi irwanya agaciro kanini. Agaciro ko kurwanya ceramic kirimo karubone nanotubes no guhimba hamwe na karubone na karubon nanotubes hamwe na grarsitubes ya karubone hamwe na gray-difene ebyiri itezimbere ihohoterwa ryibikoresho.
Hamwe no kwiyongera kwigihe cyo kwibiza (19.5 h), guhangana kwa subst yambaye ubusa, byerekana ko biri murwego rwa kabiri rwa kaburimbo kandi yicyuma oxide yakozwe hejuru ya substrate. Mu buryo nk'ubwo, kwiyongera kw'igihe, kurwanya indwara ya alumina ceramic nabyo byiyongera, byerekana ko muri iki gihe, nubwo hari ingaruka zidasanzwe zo gupfukama, nubwo hari ingaruka zidasanzwe zo gupfumba ceramic, nubwo hariho ingaruka zidasanzwe zo gupfumbanya ceramic, nubwo hariho ingaruka zidasanzwe zo gupfukama, nubwo hari ingaruka zidasanzwe zo gupfumbanya ceramic, nubwo hariho ingaruka zidasanzwe zo gupfukama, nubwo hari ingaruka zidasanzwe zo gupfukama, nubwo hariho Ingaruka yo Gukunda CERATIC, ARIKO HARI IMBERE YO GUHINDUKA ZIKURIKIRA / MATRIDE binyuze mu bitekerezo.
Ugereranije n'inzu ya alumina irimo 0.2 Kugeza 22.94%, 25.60% na 9.61%, byerekana ko electrolyte itinjiye Mu ngingo iri hagati yimyenda hamwe na substrate muri iki gihe, iyi ni ukubera ko imiterere ya karubone nanotubes na graffene bibuza kugwa hasi ya electrolyte, bityo birinda matrix. Ingaruka ya synorgistic yibi byombi iragenzurwa. Icyubahiro kirimo ibikoresho bibiri nano bifite imbaraga zo kurwanya indwara.
Binyuze kuri Tafel Umurongo wa Tafel hamwe no guhinduranya agaciro k'amashanyarazi, harasanga ahitwa Gramic ya Alumina, kandi imvange zabo zirashobora guteza imbere indwara y'ibyuma Matrix, kandi imvange zabo zirashobora kunoza indwara ya matrix, kandi ingaruka za none zishobora kurushaho kunoza urusaku kurwanya indege ifatika yo gupfuka. Kugirango ushobore gusuzuma ingaruka za NANO INGABIRE KUBIKORWA BYITONGANIRA BITANDUKANYE, LIRFHOOKE YUBUYOBOZI CY'IGIHE CYIZA.
