Qhov kev siv tam sim no ntawm hluav taws xob cua sov raj yog dab tsi?

Qhov kev siv tam sim no ntawm hluav taws xob cua sov raj yog dab tsi?

Teb: Tam sim no siv, luv luv li tam sim no, hais txog tus nqi hluav taws xob dhau los ntawm ntu ntu ntawm tus neeg xyuas pib hauv ib lub sijhawm. Chav tsev yog ampere, abbreviated li ampere (A).

24. Dab tsi yog qhov ceev tam sim no? Yuav xam li cas?

Teb: Qhov ceev tam sim no yog hais txog qhov siv tam sim no rau ib cheeb tsam ntawm cov electrode. Electroplating yog nyob ntawm ib square decimeter, yog li qhov kev siv tam sim no dhau los ntawm ib square decimeter ntawm thaj chaw electrode hu ua qhov ceev tam sim no ntawm electrode. Lub cathode tam sim no ceev yog sawv cev los ntawm DK, thiab cov anode tam sim no ceev yog sawv cev los ntawm DA, nyob rau hauv amperes ib square decimeter, piv txwv li A / d ㎡. (Nws kuj tau hais tawm hauv amperes ib square inch hauv txawv teb chaws). Piv txwv li, yog tias tag nrho cheeb tsam ntawm daim plated yog 50 square decimeters thiab tam sim no siv yog 100 amperes, qhov ceev tam sim no yog 100 amperes ÷ 50 square decimeters =2 amperes/square decimeters. Lub cathode tam sim no ntom ntom muaj qhov cuam tshuam loj rau qhov zoo ntawm cov txheej, thiab siab lossis qis tam sim no tuaj yeem ua rau cov txheej txheem tsis zoo. Qhov ceev tam sim no kuj ncaj qha txiav txim siab tus nqi ntawm cov txheej txheej thiab cuam tshuam rau kev tsim khoom.

25. Tam sim no efficiency yog dab tsi?

Teb: Qhov hnyav ntawm cov hlau precipitated ntawm lub cathode los ntawm qhov tam sim no dhau los ntawm cov tshuaj electroplating tsis tas yuav tsum sib npaug ntawm qhov hnyav suav nrog txoj cai electrolysis (qhov hnyav ntawm cov khoom siv los yog yaj ntawm lub rooj tsavxwm thaum electrolysis yog proportional rau tus nqi. hluav taws xob dhau los), thiab feem ntau tsawg dua li qhov theoretical npaum li cas. Qhov no yog vim tias electrolysis tsis tsuas yog cuam tshuam nrog kev tso tawm thiab txo cov hlau ions rau cov hlau, tab sis kuj muaj lwm yam kev cuam tshuam sab nraud. Piv txwv li, nag lossis daus ntawm hydrogen yuav siv qee qhov hluav taws xob. Yog li ntawd, thaum ib tug npaum li cas ntawm cov hlau yuav tsum tau precipitated, qhov tiag tiag tam sim no yuav tsum tau ntau tshaj qhov theoretical xam tus nqi. Yog li ntawd, qhov piv ntawm tus nqi tam sim no uas yuav tsum tau suav theoretically rau tus nqi tam sim no tiag tiag yog hu ua kev ua haujlwm tam sim no. Qhov siab dua qhov kev ua haujlwm tam sim no, qhov pov tseg ntawm hluav taws xob tsawg dua.
