Ho hloekisa

Ho na le tlhoekiso e arohaneng ea likarolo le ho hloekisa li-cores tsa radiator.Nakong ena, ho laola mocheso le mahloriso a sesebelisoa sa ho hloekisa le ho boloka mocheso le mahloriso a sesebelisoa sa ho hloekisa ka boleng bo nepahetseng haholoanyane ke mehato ea bohlokoa ea ho hloekisa.Boiphihlelo bo sebetsang bo bontša hore mocheso oa ho hloekisa oa 40 ° C ho ea ho 55 ° C le "concentration ea 20%" ke litekanyetso tse molemo ka ho fetisisa tsa ho hloekisa likarolo tsa radiator tsa aluminium.(Mona ho bua ka aluminium e hloekisang tikoloho, boleng ba pH: 10; lisebelisoa tsa ho hloekisa tsa mefuta e fapaneng kapa maemo a pH li hloka ho netefatsoa pele li sebelisoa)

Haeba ho e-na le phallo e lekaneng, ho ka khoneha ho tiisa mosebetsi ntle le ho hloekisa, empa ho hloekisa ho tla fella ka ts'ebetso e kopanetsoeng haholoanyane, e ka fokotsang palo ea phallo e sebelisoang le ho fumana sehlahisoa se setle se cheselitsoeng.Ho hloeka ha workpiece ho tla boela ho ama palo ea ho roala ha flux.

Ho fafatsa ho phalla

Ho fafatsa phallo holim'a likarolo tsa aluminium ke ts'ebetso ea bohlokoa ho Nocolok.Ts'ebetso ea brazing, boleng ba ho fafatsa flux bo tla ama ka kotloloho boleng ba brazing.Hobane ho na le filimi ea oxide holim'a aluminium.Filimi ea oxide e holim'a aluminium e tla sitisa ho kolobisa holimo le ho phalla ha fiber e qhibilihisitsoeng.Filimi ea oxide e tlameha ho tlosoa kapa ho phunngoa ho etsa weld.

Karolo ea ho phalla: 1) Senya filimi ea oxide holim'a aluminium;2) Khothalletsa ho phalla le ho phalla ha solder;3) Thibela bokaholimo ho tsoa ho oxidizing nakong ea ts'ebetso ea brazing.Ka mor'a hore brazing e phethoe, ho phalla ho tla etsa filimi e sireletsang ka ho khomarela ka matla holim'a karolo ea aluminium.Lera lena la filimi ha e le hantle ha le na phello e mpe mosebetsing oa sehlahisoa, empa le ka ntlafatsa haholo bokhoni ba likarolo tsa aluminium ho hanela kutu e ka ntle.
