Mukugadzirwa kwemaindasitiri. MaCasters, sechikamu chakakosha chehunyanzvi hwayo hwekurapa pamusoro, zvakakosha kuti chigadzirwa chiwedzere kunaka, kugara kwenguva refu uye kuramba ngura. Kugadzira maGalvaning senzira yakajairika yekurapa pamusoro. Inoshandiswa zvakanyanya mukurapa pamusoro pemacaster alloys. Chinyorwa chino chichatsanangura nzira dzakawanda dzakajairika dzekugadzira macalvers, dzinosanganisira cyanide galvanizing, zincate galvanizing, chloride galvanizing, uye sulfate galvanizing. Yakagadzirirwa kupa vaverengi ruzivo rwakakwana rwehunyanzvi.
1, Cyanide galvanization
Kugadzira simbi yecyanide, nekuda kwesimba rayo guru rekupararira uye kunaka kwayo kwekuputira. Pane imwe nguva yaimbove nechinzvimbo chakakosha muindasitiri yekuputira simbi yemagetsi. Zvisinei. Nekuda kwehunhu hwayo hune chepfu hwakawanda hwecyanide pachayo uye njodzi inogona kuitika kunharaunda. Kushandiswa kwayo kwakaganhurirwa zvakanyanya. Zvisinei, kugadzirwa kwemaitiro ekugadzira simbi yecyanide yakaderera (microcyanide). Zvichigoneka kuvimbisa mhando yechigadzirwa ukuwo njodzi dzenharaunda dzichideredzwa. Pasi pemaitiro ekugadzira simbi yecyanide, mhando yechigadzirwa yakanaka kwazvo mushure mekuputira chikamu chesimbi che hardware. Kunyanya mushure mekunge simbi yemavara yapera, mavara anoramba akajeka kwenguva yakareba.
2, mazwi ane chekuita ne "zincate galvanized caster welding" uye pfungwa dzakabatana
Maitiro ekugadzira zincate galvanizing inzira isingakuvadzi nharaunda pane cyanide galvanizing. Parizvino, akakamurwa kuita "DPE" series yeWuhan Institute of Materials Protection uye "DE" series yeGuangdian Institute. Ose ari maviri ane zincate galvanized ane alkaline additives. Ane hunhu hwe columnar lattice structure ye plating, anodzivirira ngura zvakanaka, uye akakodzera color galvanizing. Maitiro ayo akajairika anosanganisira NaOH, ZnO, nezvimwe zvinowedzera. Semuenzaniso, musanganiswa we "DPE-II" uye ethanolamine. Maitiro aya anoda kudzora kwakasimba kwekugadzirwa kwe plating solution nemamiriro e process, akadai se pH, tembiricha, uye current density, kuti ave nechokwadi chekuti plating yacho yakanaka. Mushure mekunge chigadzirwa chabuda mutangi, chinofanira kupfuura nematanho akatevedzana ekugadzirisa mushure me processing, akadai sekugeza, kupolisha, kupfavisa uye kuomesa, kuti pave nemhedzisiro yakanaka.
3, chloride galvanization
Maitiro ekugadzira chloride galvanizing anoshandiswa zvakanyanya muindasitiri ye caster hardware plating. Chikamu chacho chinodarika 40%. Chitarisiko chemaitiro acho chakafanana neche chrome plating. Uye mutengo wakaderera. Mafomu akajairika ekugadzira chloride galvanizing anosanganisira KCl, ZnCl_2, H_3BO_3 (buffer), uye ma brighteners chaiwo. Maitiro acho anonyanya kukodzera white passivation (bhuruu-chena, sirivha-chena). Pakati pawo, sirivha-chena passivation nekuda kweruvara rwayo rwakagadzikana. Kazhinji inosarudzwa sesarudzo yekutanga. Zvisinei. Zvakakosha kuziva kuti Chloride galvanized coatings, kana yakavhenekerwa nemhepo kwenguva yakareba, membrane inogona kuchinja ruvara. Inokanganisa chitarisiko uye kuramba ngura kwechigadzirwa. Saka. Mukuita, zvakakosha kutora matanho akakodzera kudzivirira kuchinja ruvara.
4, Kugadzika kwesimbi yesulfate
Maitiro ekugadzira sulfate galvanizing, ane mutengo wakaderera uye akakodzera kuputirwa nguva dzose (semuenzaniso, waya, strip, nezvimwewo). Nzvimbo muindasitiri yekugadzira electroplating. Maitiro akajairika ekuita uku anosanganisira ZnSO_4, H_3BO_3, uye ma brighteners chaiwo. pH kukosha kwe sulfate galvanizing inowanzo dzorwa pakati pe4.5 ne5.5. Nekugadzirisa kuumbwa kwe plating solution nemamiriro ekushanda, A coating ine resistance yakanaka ye corrosion uye kupenya inogona kuwanikwa. Zvisinei. Zvichienzaniswa nedzimwe nzira dze galvanizing, Sulfate galvanizing inogona kunge yakaderera zvishoma maererano ne gloss uye kufanana kwe coating.
mashoko ekupedzisa
Muchidimbu. Magasi anogadzirwa nemagetsi akasiyana-siyana. Nzira imwe neimwe ine zvayakanakira zvayo uye huwandu hwekushandiswa kwayo. Mukuita kwayo. Inofanira kunge yakavakirwa pamamiriro ekushandiswa chaiwo uye zvinodiwa zvegasi. Sarudza maitiro akakodzera ekugadzira magasi. Panguva iyi. Nemitemo yezvakatipoteredza iri kuramba ichioma uye kufambira mberi muhunyanzvi hwekugadzira magasi, maitiro ekugadzira magasi ane hushamwari kune zvakatipoteredza, anoshanda uye asingadhuri achava maitiro ekuvandudza mune ramangwana.
