Pākahiko kawakore me ratou painga

ki tonu te ao hou i te hikohiko: i te pūrere iti i roto i te puka o te kasa ki taputapu nui i roto i te wāhi mahi. Ko te mahi e kore e katoa o ratou i te puna tika o pūngao, he tokomaha o ratou e mahi i roto i ngā pūrere pūkoro, mo te tauira, pērā i ngā pākahiko kawakore.

I roto ia ratou e rua ngā momo matua: rino-nika me nika-cadmium. Papatipu mō paraharaha pūhiko pai o momo e rua te mea he hydrate o nika waikura mo te kino ko reira he ranunga o te cadmium me rino. pūhiko kawakore rechargeable tīmata hoko nāianei ki te 1.5 i roto i., I muri nei te ngaohiko āta nui haere ki te 1.8 volts. Me kï reira e ka tuku iho te pāmahana te kaha pūhiko iti e 0.5% mo nga tohu.

Kia haapapu o nga painga e kawakore pūhiko ki arahi-waikawa:

1. I roto i to ratou hanga e kore e whakamahi i ārahi onge, me te kau.

2. ake kaha mīhini me te taikaha (pupuhi kahore wehi, wiri, me poto-iahiko).

He nui roa 3. kawakore pākahiko, ara i muri roa te wa mangere.

4. kohu me haurehu pūhiko kino hua iti.

5. Ina whakaritea ki mata, he tino ngāwari ratou.

6. Iti tono ki te waiho.

hoki i huakore pūhiko kawakore:

he iti iho i taua o te mata 1. EMF - waikawa.

2. hua i raro e pā ana ki 40 - 50%.

3. Ko nui teitei te utu.

I teie mahana, Kei te whakamahia pākahiko kawakore anake i runga i mihini kawea e mahi i roto i raro i ngā āhuatanga tino, te wahi mauroa tika, me te tika (hanga, me te mīhini ahuwhenua) ranei. Kia kōrero a pā ana ki te momo matua e rua o pākahiko, ara nika-cadmium me hydride nika-whakarewa.

whakaputaina nga pākahiko nika-cadmium tuatahi i roto i 1950. Mai reira, kua tino tirotiro ratou. Whakapai ake o ngā hangarau production auaha tukua i nga wa ki te whakapiki ake i ō rātou mahi. Kei te kaha whakamahia te kaha o enei pākahiko i pūmārō rerekē (ara i roto i te wāhi) me taputapu motuhake. He mea nui ki te mōhio e rerekē te hanga kāinga o tenei momo i analogues ke, t. Ki. ratou production ki waho ko wā motuhake mō ngā hiahia kiritaki motuhake.

Nika whakarewa hydride kawakore he iti rongonui pākahiko e tika ana ki te meka i runga i te tekau tau whakamutunga kaha aki ratou tauira nika-cadmium. Kua whakaaetia rangahau Tata tino whakapai ake i to ratou mahi. No te mea o whakaaro o te haumaru te taiao ako cadmium pākahiko te āta heke, ka kua hoatu hiahia ki hydride whakarewa, engari kāore, e kore kua ratou rongonui riro whakauka.

I te mutunga kia tuhia te reira e te tōtika, me tino nui, te roanga o te mahi i roto i te matua ti'aturi i runga i tohutohutia whakaaro ki te whakarato i te mana pū o te tukanga e mea i raro i ngā āhuatanga rerekē. Na reira, hoko pākahiko kawakore, āta titiro ratou āhuatanga me nga tikanga o to ratou mahi.
