Apickling mokhoa le tshebetso ya ka ho nepahetseng seamless tšepe phala

1. Precision seamless tšepe phala pickling tshebetso

Precision seamless tšepe phala pickling mokhoa haholo-holo e kenyeletsa inregnated acid e ho hlatsoa mokhoa, fafatsa asiti ho hlatsoa mokhoa le acid peista mafome ho tloswa method.Kakaretso, re sebelisa e inregnated acid e ho hlatsoa mokhoa, le mokhoa spray ka sebelisoa ka tlhahiso ea boima.Likarolo tsa tšepe ka kakaretso pickling ka 10% ~ 20% (bolume) tharollo ea sulfuric acid ka mocheso oa 40 C. Ha tharollo ea tšepe e feta 80g / L le ferrous sulfate e feta 215g / L, lotion ea acid e lokela ho nkeloa sebaka.Mocheso oa kamore, ka 20 % ~ 80% (bolumo) ea tharollo ea hydrochloric acid bakeng sa pickling ea tšepe, ha ho bonolo ho etsahala ho bola le hydrogen brittle phenomenon.Ka lebaka la phello e kholo e senyang ea asiti holim'a tšepe, corrosion inhibitor ea eketsoa.Ka mor'a ho hloekisa, bokaholimo ba tšepe bo fetoha bosoeu ba silevera. , le ho fetisa bokaholimo ho ntlafatsa ho hanyetsa ha kutu ea tšepe e sa hloekang.

E le hore u felise adsorption ea holim'a metsi le ho fokotsa mohatla oa chromatographic tlhōrō ea ho hula, motho ea tsamaisang thepa o lokela ho phekoloa ka ho hlatsoa acid kapa ho hlatsoa alkali pele ho sebelisoa. , e hloekisitsoeng, e hlatsoitsoe hore e se nke lehlakore, 'me e omisitsoe.Ho hlatsoa asiti ho ka tlosa tšepe, aluminium, k'halsiamo, magnesium le litšila tse ling holim'a tafole, empa e ke ke ea tlosa sehlopha sa joala sa silicone.

2.Phello ea ho pickling e nepahetseng ea tšepe e se nang seamless

Tlosa oli le mafome a phala e nepahetseng ea tšepe e se nang seamless ho itokisetsa ts'ebetso e latelang. Ts'ebetsong ea tlhahiso, ts'ebetso ea pickling ke ho tlosa letlalo la oxidation, ka mor'a phekolo ea lubrication (carbon steel-phosphorus saponification, stainless steel-botter lime, koporo ea aluminium pipe. -oli), e nang le mokhoa oa khale-copper plating), ebe ho ntšoa le ts'ebetso e tebileng.Haeba phala ea tšepe e se pickling, ho ka 'na ha e-ba le oxide le oli holim'a metsi.Tšilafalo, matla a nyutlelie a phosphoride ha a khone ho li tlosa, boleng ba phosphorization bo tla fokotseha.
