Txhawm rau kom nrawm nrawm ntawm aluminium alkaline etching, tuaj yeem nyob rau hauv sodium hydroxide raws li lub hauv paus ntawm alkaline etching tov nrog sodium nitrate thiab sodium nitrite, ntxiv rau txiv hmab txiv ntoo additive xws li sodium txoj kev, ntxiv rau tank kua concentration, kub, lub sij hawm etching ntawm yam yuav cuam tshuam tus nqi ntawm industrial aluminium alkaline etching, thiab yuav ua li cas tswj cov yam ntxwv no.
Da dej concentration
Yuav dhau los ua alkaline sodium hydroxide yaj hauv dej, cov tshuaj no feem ntau yog siv hauv txhuas profile siv tshuaj ntxuav lub tank tov, uas yog alkaline etching tov, alkaline etching tov ntawm sodium hydroxide yog ion lub xeev ntawm lub neej, raws li qhov concentration ntawm sodium hydroxide nce. mus txog 250 g / L, ceev kuj nce raws li kev yaig ntawm cov khoom siv txhuas profile, yog li nws tuaj yeem pom, qhov siab dua ntawm sodium hydroxide nyob rau hauv lub tank, qhov nrawm nrawm dua, tab sis tam sim no ntau lub lag luam txhawm rau txuag nqi, Cov ntsiab lus ntawm sodium hydroxide yog tswj nyob rau hauv thaj tsam ntawm 50-100g / L.In thiaj li tswj cov ntsiab lus ntawm sodium hydroxide, gluconate tuaj yeem muab ntxiv rau hauv lub tank tov los ntawm kev ntxiv cov khoom siv ntev ntev los ua kom cov ntsiab lus ntawm sodium hydroxide dawb hauv qhov ntau. ntawm 70 g / L.
Tus nqi ntawm soluble
Cov txhuas hauv cov tshuaj sodium hydroxide alkaline reacts nrog sodium hydroxide los tsim cov txhuas hydroxide, txhuas yog cuam tshuam los ntawm cov khoom, aluminium etching tus nqi txo qis, cov kev sim qhia tau hais tias thaum tus nqi ntawm cov txhuas yaj ntawm 26 g / L, qhov concentration ntawm sodium hydroxide rau. 50 g / L, qhov kub thiab txias, qhov yaig qeeb ntawm txhuas, yog li, da dej concentration nyob rau hauv cov xwm txheej tsis hloov pauv, qhov ntau dua cov yaj ntawm aluminium, qhov qeeb qeeb ntawm etching ceev, uas yog, tus nqi ntawm txhuas yaj yog inversely. proportional rau etching ceev.Rau kom tau qhov tsim nyog tus nqi ntawm txhuas los ntawm kev xam, them sai sai rau qhov kev hloov ntawm tank kua, raws li qhov teeb meem yuav yaj nyob rau hauv tus nqi ntawm txhuas tswj nyob rau hauv lub teev ntau yam.
Da dej kub
Los ntawm kev sim ntawm 6063 txhuas profile, peb kos qhov xaus tias nrog qhov kub thiab txias ntawm chav da dej, qhov ceev ntawm txhuas corrosion kuj tseem nce sai, qhov kub ntawm txhua txhua 10 ℃, qhov ceev ntawm txhuas corrosion tshuaj yuav nce 1 zaug, yog li cov siab dua qhov kub, qhov ceev ntawm txhuas alkali corrosion yog ceev, uas yog hais tias, qhov kub ntawm lub da dej yog proportional rau qhov ceev ntawm corrosion.Qhov no yog vim hais tias cov txhuas profile nyob rau hauv alkali etching tov etching yog ib tug exothermic cov tshuaj tiv thaiv, muaj peev xwm tso tawm 20KW. / m² ntawm cov cua sov, feem ntau yuav tsum tau nruab ib lub tshuab cua txias uas muaj peev xwm ua kom txias txaus, kom lub tank ua kua kub nyob rau hauv thaj tsam ntawm 50-60 ℃², cov cuab yeej no nyob rau lub caij ntuj no thiab tuaj yeem siv los ua cov khoom cua sov.
Lub sijhawm etching
Nyob rau hauv cov tshuaj tiv thaiv alkali yaig, qhov ntev ntawm kev yaig ntawm kev lag luam aluminium profile, aluminium yaj qhov hnyav dua, thiab lub sij hawm etching thiab etching ceev thiab tsis muaj kev sib raug zoo, luv lub sij hawm etching tsuas yog txo qhov hnyav ntawm aluminium yaj. , txo cov reagent noj, alkaline etching thiab etching ceev tawm ntawm kev faib ua feem, yog hais tias koj xav tau tus du nto ntawm aluminium profile, koj tuaj yeem ua ntej siv cov txheej txheem ntawm txhua yam txhuam los yog sandblasting rau txheej txheem, lossis los ntawm kev txhim kho cov pwm zoo. thiab extrusion txheej txheem zoo kom ua tiav cov nyhuv ci thiab du.
