Yankho lalifupi choyamba: onse awiri amatha kubweretsa kukana kwa nthaka yolephera m'njira yodziwika bwino, koma amathetsa vutoli m'njira zosiyana kwambiri - ndipo kusiyana kumeneku kumawonekera m'chaka chachitatu, osati patsiku loyambitsa.Gawo lopopera la graphite limachepetsa kukana kwa nthaka mopanda mphamvu: thupi la kaboni losagwiritsa ntchito chinyezi, lomwe silili lachitsulo lomwe limakulitsa malo olumikizirana bwino ndi nthaka ndipo limagwira ntchito kwa zaka zambiri popanda kudzazanso madzi. Electrode ya mankhwala imachepetsa kukana kwa nthaka mwachangu: chubu cha mkuwa chokhala ndi mchere wa electrolytic womwe umatulutsa ma ayoni oyendetsera nthaka m'nthaka yozungulira - wamphamvu tsiku loyamba, koma umadalira chinyezi komanso mphamvu ya mchere yomwe imakhalapo nthawi zonse.Mu zaka 12 zomwe ndakhala ndikupereka ukadaulo wonse kuchokera ku fakitale yathu ya Xinchang, ndaona mainjiniya opanga mapangidwe akusankha molakwika mbali zonse ziwiri. Bukuli limakupatsani fizikisi, miyezo, masamu osamalira komanso njira yosankha — kotero mutha kusankha kamodzi ndikuteteza chisankho chimenecho kwa kasitomala wanu.
- Timamanga gawo la nthaka la graphite kuti ligwire ntchito mopanda kusokoneza pokulitsa malo olumikizirana ndi ma electrode ndikusunga chinyezi cha nthaka, kuti magwiridwe ake asadalire mphamvu ya mankhwala yomwe ingagwiritsidwe ntchito.
- Ma electrode a mankhwala amagwira ntchito mwakhama potulutsa mchere wa electrolytic m'nthaka, zomwe zimapangitsa kuti pakhale kukana kwakukulu koyambirira koma zimagwirizanitsa magwiridwe antchito a nthawi yayitali ndi chinyezi ndi kudzazanso.
- Timadalira IEC 62561-7:2024 chifukwa imafotokoza bwino mayeso omwe amavumbula chinthu chofooka — kutuluka kwa madzi, kudziwa sulfure, kukana, kuyeza pH ndi dzimbiri — ndipo tikukulimbikitsani kuti mufunse umboni wochokera kwa wogulitsa aliyense.
- Mu mtengo wathu wotumizira kunja, ma electrode a mankhwala nthawi zambiri amawononga ndalama zokwana 20% mpaka 40% kuposa module ya graphite, makamaka chifukwa cha thupi la chubu cha mkuwa ndi mphamvu ya mchere yomwe imanyamula.
- Fakitale yathu imapanga zinthu zokwana 10,000 pamwezi zopangidwa ndi mizera, sikweya ndi maluwa a plum, zolongedzedwa m'mabokosi amatabwa ndikutumizidwa kuchokera ku Shanghai kapena Ningbo.
Pamene woyesa nthaka sakugwirizana ndi chithunzicho: kodi vuto la kukana nthaka kwenikweni limayambira kuti?
Ndiyambe ndi chiganizo chomwe ndimamva pafupifupi pa nthawi iliyonse yothetsa mavuto: “Tinayika zonse zomwe chithunzicho chinanena, ndipo kuwerenga sikunathebe.” Chithunzicho sichinali cholakwika ndi zipangizo — sichinatchulepo za nthaka.Kukana kwa nthaka kumayendetsedwa ndi nthaka mkati mwa mamita ochepa kuchokera ku electrode, kotero nthakayo ikakhala pa mamita mazana angapo a ohm-mita, kuwonjezera ndodo zina zopanda kanthu kumabweretsa kusintha pang'ono kochititsa manyazi.Chifukwa chake ndi geometry, osati luso: ndodo iliyonse imataya mphamvu yake m'dothi lozungulira lokha, ndipo ndodo zapafupi zikangofanana, ndodo iliyonse yowonjezera imabwereka dothi lomwe latchulidwa kale. Kuwirikiza kawiri chiwerengero cha ndodo mu dothi lolimba lomwe silingathe kupirira sikuchepetsa kukana kwake ndi theka - mu ndemanga zathu zoyezera, phindu lochokera ku ndodo yachiwiri nthawi zambiri silili bwino kuposa lomwe loyamba linapereka.
Zotsatira zake zophatikizana ndi chifukwa chake sitikuwonanso "kuwonjezera ndodo zambiri" ngati yankho lofunika kwambiri ku nthaka yoipa. Yankho lolondola ndikusintha momwe nthaka imagwirira ntchito mozungulira electrode, ndipo ukadaulo uwiri ukutsogolera mndandanda wathu wachidule: graphite ground module ndi chemical electrode.Zonsezi zimaukira chosinthika chomwecho — kukana ndi kukhudzana kwa nthaka komwe kumazungulira electrode — koma zimaukira ndi malingaliro osiyana, ndipo kusiyana kwa filosofi ndiko komwe nkhaniyi ikunena.Chinthu chilichonse chisanayambe kukambirana, mfundo imodzi ndi yofunika kwambiri:Yesani nthaka kaye, ndi kafukufuku woyenera wa ma electrode anayi monga momwe tafotokozera muIEEE Std 81, chifukwa palibe deta yazinthu zomwe zingalowe m'malo mwa mbiri ya resistivity ya tsamba lanu lenileni.
Malingaliro awiri omwe ali mu ngalande imodzi: kodi ukadaulo uliwonse umachepetsa bwanji kukana?
Timalongosola gawo la graphite ngati yankho la mainjiniya osachitapo kanthu.Zathugawo la nthaka ya graphitendipo zakembale wa kaboni wochepa mphamvuAmapangidwa ndi cholumikizira chokhazikika chomwe sichili chachitsulo chomwe chimayamwa ndi kusunga chinyezi, chimasunga kukhudzana kwapafupi ndi nthaka yozungulira, komanso chimakhala ndi malo olumikizirana bwino kwambiri kuposa ndodo yopanda kanthu.Ndimabwerezabwereza ku zinthu zitatu zomwe zalembedwa m'mabuku athu a kapangidwe kake: mphamvu ya mpweya siikhudzidwa ndi nyengo; thupi siliuma kapena kusweka chifukwa cha kugwedezeka kwamphamvu kwa mphamvu yamagetsi; ndipo kukana kumakhala kotsika komanso kokhazikika kwa nthawi yayitali chifukwa palibe chomwe chimadyedwa mkati. Timawapanga m'mizere, sikweya ndi maluwa a plum, ndipo mizere ndi mawonekedwe omwe ndimawatchula kwambiri a nthaka yamiyala ndi mabowo obowoka.
Timalongosola ma electrode a mankhwala ngati yankho la mainjiniya wogwira ntchito.Ma electrode a mankhwala ndi chubu cha mkuwa chobowoledwa ndi fakitale chomwe chili ndi mchere wa electrolytic; chinyezi cha nthaka chimalowa kudzera m'mabowo opumira, chimasungunula mcherewo, ndikunyamula ma ayoni oyendetsera mpweya kupita nawo kudziko lozungulira, zomwe zimachepetsa mphamvu ya mankhwala yolimbana ndi nthaka yokha.Tawona zotsatira zake pa kulephera kwa kuwerenga kukhala zazikulu, ndipo pa malo olimbana kwambiri ndi cholinga chofuna kudziwa zambiri - malo olumikizirana a mapiri pa granite, mwachitsanzo - nthawi zina mankhwala amafika pamlingo womwe kukula kwa malo osakhazikika sikungathe. Nthawi zonse timakumbutsa ogula za mtengo wa mphamvu imeneyo: makinawo amagwira ntchito pokhapokha ngati madzi ndi mchere zikupitirirabe.
Chaka chachitatu ndicho chofunikira kwambiri: nchiyani chimachitika mchere ukatuluka?
Ndiloleni ndikuwonetseni gawo la kufananiza komwe nthawi zambiri sikutha kukhala m'mabuku otsatsa malonda.Njira yofanana yochotsera madzi yomwe imapangitsa kuti ma electrode a mankhwala azigwira ntchito bwino ndiyonso njira yake yokalamba — mvula iliyonse yomwe imanyamula ma ayoni m'nthaka imanyamula mphamvuyo pang'onopang'ono pafupi ndi kuchepa.Timaona opanga akuyang'ana izi pogwiritsa ntchito ma refill ports ndi ma recharge kit, zomwe zimagwira ntchito bwino ngati mwini malo akusunga katunduyo — ndipo zimalephera mwakachetechete ngati palibe amene akutero. Tisanatchule za chemistry, ndimafunsa mlangizi aliyense funso limodzi: ndani, mwa mgwirizano, akudzazanso electrode iyi m'chaka chachitatu, komanso m'chaka chachisanu ndi chiwiri?
Dziko la miyezo lakwaniritsa izi.IEC 62561-7:2024tsopano ikufotokoza batire yoyesera ya zinthu zowonjezera nthaka — mayeso ochotsa madzi, kudziwa sulfure, kudziwa kukana, kuyeza pH (komwe kwangoyambitsidwa kumene mu kope la 2024) ndi mayeso a dzimbiri — chifukwa chakuti chinthucho chiyenera kukonza nthaka popanda kuwononga ma conductors omwe adakwiriridwa.Mfundo yomalizayi ikufunika kutsindika: kudzaza mchere mwamphamvu komwe kumawononga kondakitala wanu wa mphete ya mkuwa kumasintha vuto la kukana kukhala vuto la umphumphu. Timayang'ana momwe dzimbiri limagwirizanirana ndi mankhwala aliwonse, ndipo tikukulangizani kuti mufunse umboni wa mayeso a IEC 62561-7 kuchokera kwa ogulitsa aliwonse, kuphatikizapo ife.
Timakonda ma module a graphite chifukwa amapewa funso lonse.Popeza gawoli lilibe mchere komanso electrolyte, palibe chotulutsa madzi, palibe chodzazanso madzi ndipo palibe chowononga ma conductors oyandikana nawo — nthawi yokonza "imayendera chivindikiro cha dzenje nthawi zina."Pa malo opanda anthu, pamwamba pa mapiri, minda ya dzuwa ya m'chipululu ndi katundu aliyense amene mwini wake sangasayine pangano lokonza, kusiyana kumeneku nthawi zambiri kumathetsa chisankhocho mtengo usanakambidwe.
Mbali ndi mbali: ndi manambala ndi machitidwe ati omwe ayenera kutsogolera kusankha?
