What is the difference between spangle and zero-spangle of galvanized coil?

1.Irangiza kugeza ryariingoferokubikwa mu bubiko?Kuki?

Igisubizo: Biremewe kubikwa amezi atatu kugirango wirinde okiside iterwa nububiko igihe kirekire.

2. Kwihanganira uburebure ni ubuheurupapuro rw'icyuma?

Igisubizo: Kwihanganira uburebure ntibyemewe kugira agaciro keza, kandi ntarengwa ntibyemewe kurenza + 6mm.

3. Ururabo rwa Zinc ni iki?Agace gato ni iki?

Igisubizo: Uruziga runini ni uruziga rusanzwe.Ukurikije uburyo busanzwe bwo gukora, spangle nini irashobora kubyara.Diameter ya nucleus ya kirisiti ntabwo iri munsi ya 0.2mm;diameter ya nucleus ya kirisiti iri munsi ya 0.2mm, bita spangle nto.Biragaragara.

4. Ni irihe hame ryo kurindaashyushye-ashyushyeurwego?

Igisubizo: Kuberako zinc ishobora gukora firime irwanya ruswa neza hejuru yibidukikije.Ntabwo irinda urwego rwa zinc gusa, ahubwo irinda ibyuma.

5. Ni irihe hame ryo gutambutsa igiceri gishyushye?

Igisubizo: Chromate passivation ivura yaurupapuroIrashobora gukora firime ya passivation, kandi formulaire yimiti niyi ikurikira: Zn + H2GrO4-ZnGrO2 = H2

Chromium ihindagurika mumuryango wa passivation yumuti ntishobora gukemuka mumazi, ntigikora imiti, kandi ikora nka skeleton, mugihe chromium ya hexavalent ibora byoroshye mumazi kandi irashobora kugira uruhare mukwongera gutambuka mugihe firime ya passivation.Ifite ingaruka zo gukiza firime ya passivation.Kubwibyo, mugihe runaka, firime ya passivation irashobora gukumira isuri itaziguye yurupapuro rwumuyaga ukoresheje umwuka cyangwa umwuka, kandi zinc igira uruhare mukurinda.

6. Nubuhe buryo bwo gupima ruswa yo kurwanyaurupapuro rushyushye?

Igisubizo: Hariho uburyo butatu bwo kugerageza kwangirika kwangirika kumpapuro zishyushye: gupima umunyu;ikizamini cy'ubushuhe;ikizamini cy'isuri.

7. Ni kubera iki hakwiye gukorerwa imiti igabanya ubukana ku bicuruzwa bishyushye?

Igisubizo: Iyo urupapuro rushyushye ruri mu kirere cyuzuye, cyane cyane iyo umwuka urimo ibintu bya acide nka SiO2, CO2, NO2 na OYA, ubuso bwurwego rwa galvaniside bizahita bibora ingese yera.Ibice byingenzi bigize ingese zera ni ZnO na Zn (OH) 2. Ubu bwoko bwingese zera ntibuhindura isura gusa, ahubwo buzana ingorane zikomeye zo gukoresha ejo hazaza.

8. Ni izihe mpamvu zitera ingese yera kuriingofero?

Igisubizo: Impamvu zitera ingese zera ni: gushyushya-gushya bishyirwa hamwe nibindi bitangazamakuru byangirika nka aside, alkali n'umunyu;firime ya passivation cyangwa anti-firime yangiritse;ingaruka za passivation cyangwa amavuta ntabwo aribyiza;ububiko bwububiko ntabwo buhumeka neza, Ubushuhe;urupapuro rwa galvaniside rusutswe namazi mugihe cyo gutwara;gutwarwa ku bushyuhe buke kandi bikabikwa ku bushyuhe bwo hejuru, bikora kondegene.
