Ingufu zisubiza inyuma ni ubwoko bw'ingufu zishobora guhindura polarity y'amashanyarazi zisohora. Zikunze gukoreshwa mu gutunganya amashanyarazi, gukoresha electroplating, ubushakashatsi ku ingese, no gutunganya ubuso bw'ibikoresho. Ikiranga cyazo cy'ingenzi ni ubushobozi bwo guhindura byihuse icyerekezo cy'ubukonje (political/negative polarity switching) kugira ngo zihuze n'ibisabwa byihariye.
I. Ibintu by'ingenzi biranga amashanyarazi asubira inyuma
1. Guhindura Polarite byihuse
● Voltage y'umusaruro ishobora guhinduranya hagati ya polarity nziza na negative hamwe n'igihe gito cyo guhinduranya (kuva kuri milisegonda kugeza ku masegonda).
● Bikwiriye gukoreshwa mu gusaba guhindura ikirere mu buryo buhoraho, nko gukoresha amashanyarazi mu buryo bwa pulse no gukoresha amashanyarazi mu buryo bwa electrolytic.
2. Icyerekezo cy'ubushyuhe gigenzurwa
● Ishyigikira umuyoboro uhoraho (CC), voltage ihoraho (CV), cyangwa uburyo bwo gutera umuvuduko, hamwe n'igenamiterere rishobora gutegurwa kugira ngo rihindurwe, imikorere y'akazi, n'ibindi bipimo.
● Bikwiriye ibikorwa bisaba kugenzura neza icyerekezo cy'amashanyarazi, nko gusiga amashanyarazi no gushyira amashanyarazi mu mwanya wayo.
3. Ingufu nkeya n'ubudahangarwa bwinshi
● Ikoresha ikoranabuhanga ryo guhinduranya rikoresha frequency nyinshi cyangwa ikoranabuhanga ryo kugenzura umurongo kugira ngo ihamye ko umuvuduko w'amashanyarazi/voltage uhoraho, bigabanye ingaruka z'imikorere.
● Ni byiza cyane mu igerageza ry’amashanyarazi cyangwa imashini zikoreshwa mu nganda.
4. Imirimo yo Kurinda Ihagije
● Ifite uburinzi bukabije bw'amashanyarazi, ubushyuhe bukabije, ubushyuhe buciriritse, n'ubushyuhe bukabije kugira ngo hirindwe kwangirika kw'ibikoresho mu gihe cyo guhindura polarite.
● Hari ubwoko bugezweho bushyigikira gutangira buhoro buhoro kugira ngo bugabanye kwiyongera kw'amashanyarazi mu gihe cyo gusubira inyuma.
5. Igenzura rishobora gukorwa kuri gahunda
● Ishyigikira ibikorwa byo hanze (nk'uburyo bwa PLC cyangwa PC control) kugira ngo ihindure imikorere mu buryo bwikora, ikwiriye imiyoboro y'inganda.
● Yemerera gushyiraho igihe cyo gusubira inyuma, imikorere y'umuvuduko, amplitude y'umuvuduko/voltage, n'ibindi bipimo.
II. Imikoreshereze isanzwe y'amashanyarazi asubira inyuma
1. Inganda zikora amashanyarazi
● Gukoresha Electroplating ya Pulse Reverse Current (PRC): Gukoresha Electroplating ya Periodic Current bituma imiterere y'igitambaro ihinduka, bigabanya imyenge, kandi bikongera gufatana. Ikoreshwa cyane mu gushushanya icyuma cy'agaciro (izahabu, ifeza), gushushanya umuringa wa PCB, gushushanya nikeli, nibindi.
● Gusana Plating: Ikoreshwa mu gusana ibice byashaje nk'amabere n'ibimera.
2. Imashini zikoresha amashanyarazi (ECM)
● Gukuraho amashanyarazi: Bishongesha amashanyarazi hakoreshejwe amashanyarazi asubira inyuma, bigatuma ubuso burushaho kumera neza.
● Gusukura hakoreshejwe Electrolytic: Bikoreshwa mu byuma bitarangwamo ifu, mu byuma bikozwe muri titaniyumu, no mu bindi bikoresho byo gusukura neza.
3. Ubushakashatsi n'Uburinzi ku birebana na Karosi
● Uburinzi bwa Cathodic: Burinda kwangirika kw'ibyuma (nk'imiyoboro n'amato) hakoreshejwe umuyoboro usubira inyuma buri gihe.
● Isuzuma rya ruswa: Rigaragaza imyitwarire y'ibikoresho mu cyerekezo gisimburana cy'umuvuduko w'amazi kugira ngo ryige uburyo bwo kurwanya ruswa.
4. Ubushakashatsi ku bateri n'ibikoresho
● Isuzuma rya bateri ya Lithium/Sodium-iyoni: Rigaragaza impinduka za polarité ya charge-discharge kugira ngo ryige imikorere ya electrode.
● Gushyiramo Electrochemical (ECD): Bikoreshwa mu gutegura ibikoresho bya nanomaterial na firime nto.
5. Izindi porogaramu z'inganda
● Kugenzura amashanyarazi: Ku bijyanye n'imikorere ya magnetization/demagnetization.
● Uburyo bwo kuvura plasma: Bukoreshwa mu nganda za semiconductor na photovoltaic mu guhindura ubuso.
III. Ibitekerezo by'ingenzi mu guhitamo amashanyarazi asubira inyuma
1. Ibipimo by'umusaruro: Voltage/current range, umuvuduko wo gusubira inyuma (igihe cyo guhindura), n'ubushobozi bwo guhindura imikorere y'umusaruro.
2. Uburyo bwo kugenzura: Guhindura intoki, gukurura hanze (TTL/PWM), cyangwa kugenzura mudasobwa (RS232/GPIB/USB).
3. Imirimo yo Kurinda: Umuriro mwinshi, umuriro mwinshi, uburinzi bw'amashanyarazi magufi, n'ubushobozi bwo gutangira buhoro.
4. Guhuza Imikoreshereze: Hitamo ubushobozi bukwiye bw'ingufu n'inshuro zo guhindura ibintu hashingiwe ku bikorwa byihariye nko gukoresha amashanyarazi cyangwa gukoresha amashanyarazi.
Guhindura ingufu bigira uruhare runini mu gutunganya amashanyarazi, gukoresha amashanyarazi, no kurinda ingese. Akamaro kabyo gakomeye kari mu guhindura polarity ishobora gukoreshwa, ibyo bigatuma umusaruro uva mu bikorwa, bikanoza ireme ry'ipamba, kandi bigateza imbere ubushakashatsi ku bikoresho. Guhitamo ingufu zihindura inyuma zikwiye bisaba isuzuma ryimbitse ry'ibipimo by'umusaruro, uburyo bwo kugenzura, n'imikorere yo kurinda kugira ngo hahuzwe n'ibikenewe mu buryo butandukanye bwo gukoresha.
