Qhov sib txawv tseem ceeb ntawm cataphoresis thiab anaphoresis yog cataphoresis yog electrophoresis ntawm cations, whereas anaphoresis yog electrophoresis ntawm anions.
Electrophoresis yog cov txheej txheem kev tshuaj ntsuam peb tuaj yeem siv los txheeb xyuas tus qauv siv cov khoom hluav taws xob ntawm cov tshuaj muaj nyob hauv cov qauv ntawd. Nyob rau hauv txoj kev no, peb tuaj yeem soj ntsuam cov lus tsa suab ntawm dispersed solute nyob rau hauv nruab nrab tsom xam. Yog li ntawd, nws yog ib qho tseem ceeb rau kev txiav txim siab cov lus tsa suab ntawm cov tshuaj lom neeg txheeb ze rau nruab nrab.
Cataphoresis yog dab tsi?
Cataphoresis yog electrophoresis ntawm cations. Qhov ntawd txhais tau hais tias, cov txheej txheem kev tshuaj ntsuam no suav nrog kev txav ntawm cations (hluav taws xob zoo them ions) ntawm cathode. Cov txheej txheem no yog qhov tseem ceeb hauv txheej txheej hlau kom tau txais qhov chaw tiv thaiv siab heev rau cov neeg ua haujlwm atmospheric.
Tsis tas li ntawd, cov txheej txheem no yog qhov tseem ceeb hauv kev tswj hwm thiab kev ncua qhov chaw uas cataphoresis yog siv los ua cov txheej txheem electrocoating ntawm cov xim mus rau ntau lub kauj. Tsis tas li ntawd, hom txheej no tuaj yeem ua rau cov khoom tiv thaiv corrosion ntawm cov khoom hlau no, thiab feem ntau nws yog txoj hauv kev rau nws pib qhov chaw uas peb xav tau kev tiv thaiv kev tiv thaiv zoo tshaj plaws.
Ntxiv mus, cataphoresis siv cov hluav taws xob tam sim no los tso cov xim rau ntawm ib feem lossis cov khoom sib dhos. Txoj kev no tuaj yeem ua cov txheej txheem hlau txawm tias nyuaj thiab cov khoom sib dhos los txiav txim siab txog cov kev cai tshwj xeeb raws li kev ua haujlwm ntawm cov hlau. Yog li ntawd, txoj kev no yog siv rau ntau yam kev siv xws li cov khoom siv ua liaj ua teb, khoom siv, tsheb, tsheb, cov khoom siv hauv hiav txwv, transformers, metallic office rooj tog, thiab cov khoom vaj khoom tsev.
Cov txheej txheem ntawm cataphoresis suav nrog kev kho ua ntej, qhov chaw raug ntxuav thiab coated nrog phosphate. Cov kauj ruam no yog qhov tseem ceeb vim nws muab cov hlau ua tiav qhov xav tau. Feem ntau, hlau thiab zinc phosphates yog siv. Tus txheej txheem ntawm pretreatment yog los ntawm lub rooj zaum tshuaj tsuag los yog immersion.
Thaum lub sijhawm thib ob, muaj cov tso tsheb hlau luam uas muaj li 80% deionized dej thiab 20% ntawm cov xim pleev xim. Dej ua raws li cov cab kuj rau cov xim khib nyiab. Tus nqi ntawm qhov voltage dictates lub thickness ntawm cov xim txheej thaum lub sij hawm cataphoresis. Cov kauj ruam tom ntej yog yaug. Cov rinsed pleev xim cov khoom rov qab mus rau lub dip tank, kom ntseeg tau tias optimum efficiency. Tom qab lub tank yaug, cov khoom yog ci hauv qhov cub, uas kho cov xim kom ntseeg tau tias qhov ua tau zoo tshaj plaws. Qhov kub ntawm qhov cub nyob ntawm qhov system siv rau cataphoresis.
Anaphoresis yog dab tsi?
Anaphoresis yog electrophoresis ntawm anions. Qhov ntawd txhais tau tias, anaphoresis suav nrog kev txav ntawm anions mus rau lub anode. Nws muaj ntau yam siv hauv kev siv tshuaj xws li kev kho tawv nqaij. Estheticians siv anaphoresis los pab txhawb kev sib sib zog nqus pore cleansing. Hauv cov qauv no, lawv siv cov galvanic tam sim no los tsim cov tshuaj tiv thaiv uas tuaj yeem emulsify lossis liquefy sebum thiab cov khib nyiab ntawm daim tawv nqaij. Qhov kev kho no yog nrov rau cov tawv nqaij oily thiab tawv nqaij uas muaj pob txuv vim tias cov txheej txheem no yuav pab kom muag muag thiab so cov khib nyiab hauv follicle. Desincrustation yog ib lub npe tshwj xeeb rau txoj kev no.
piav qhia ntxiv txog cov txheej txheem no, nws yuav tsum muaj cov tshuaj alkaline-based electronegative uas muab tso rau ntawm daim tawv nqaij. Qhov kev daws teeb meem no yuav pab kom muag cov sebum thiab cov follicles rau kev ntxuav qhov tob tob. Tom qab ntawd, thaum ua anaphoresis, tus neeg siv khoom (uas daim tawv nqaij yuav tsum tau ntxuav) tuav lub electrode zoo thaum tus kws kho hniav tuav cov electrode tsis zoo ntawm lub ntsej muag ntawm tus neeg siv khoom. Tom qab ntawd cov tshuaj tiv thaiv uas tuaj yeem hloov cov sebum mus rau hauv xab npum (saponification) tau qhib. Thaum cov hluav taws xob tam sim no cuam tshuam nrog cov ntsev ntsev ntawm daim tawv nqaij, nws tsim sodium hydroxide (vim daim tawv nqaij feem ntau muaj sodium chloride ua ntsev tivthaiv). Qhov no sodium hydroxide pab ua kom cov roj ntau dhau, txhaws qhov pores thiab lwm cov khib nyiab ntawm daim tawv nqaij, ua raws li cov tawv nqaij softening.
Qhov txawv ntawm Cataphoresis thiab Anaphoresis yog dab tsi?
Ob lub cataphoresis thiab anaphoresis yog hom electrophoresis. Qhov sib txawv tseem ceeb ntawm cataphoresis thiab anaphoresis yog cataphoresis suav nrog electrophoresis ntawm cations, whereas anaphoresis suav nrog electrophoresis ntawm anions. Tsis tas li ntawd, cataphoresis yog siv los pleev xim rau ntawm qhov chaw hlau thaum anaphoresis tseem ceeb hauv kev kho cov tawv nqaij oily thiab tawv nqaij nrog pob txuv. Yog li, qhov no yog lwm qhov sib txawv tseem ceeb ntawm cataphoresis thiab anaphoresis ntawm daim ntawv thov.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm cataphoresis thiab anaphoresis.
Summary – Cataphoresis vs Anaphoresis
Ob lub cataphoresis thiab anaphoresis yog hom electrophoresis. Qhov sib txawv tseem ceeb ntawm cataphoresis thiab anaphoresis yog cataphoresis suav nrog electrophoresis ntawm cations, whereas anaphoresis suav nrog electrophoresis ntawm anions.
