Galvanized simbi waya inoshandiswa zvakanyanya mukuvaka, hardware, waya mesh, simba uye kufonerana, kurima nekupfuya mhuka, migwagwa mikuru, uye kugadzira tambo dzesimbi. Hunhu hwechigadzirwa hunokanganisa zvakananga kuchengetedza kweprojekiti, hupenyu hwebasa, uye kuvimbika; saka, akasimba, akabatana, uye anokwana emhando zviyero zvinofanirwa kuitiswa mukati mese maitiro ekugadzira.
Mabikirwo ewaya yesimbi inopisa-yakakungurutswa yakaderera{{1}kabhoni simbi waya tsvimbo, inowanzo gadzirwa nezvinhu zvakaita seQ195, Q215, Q235, SAE 1006, SAE 1008, SAE 1010, uye SWRCH18A. Raw material quality ndicho chinhu chikuru chinotaridza ma mechanika zvivakwa, mhando yepamusoro, uye zinc plating adhesion yechigadzirwa chapera. Kabhoni inobata zvakananga kusimba, kuoma, uye kudhirowa kwewaya yesimbi uye inofanira kunyatsodzorwa: C Zvishoma pane kana kuenzana ne0.15%, Si Zvishoma pane kana kuenzana ne0.07%, Mn0.30%~0.60%, P Zvishoma pane kana kuenzana ne0.035%, S Zvishoma pane 0.0 kana kuenzana. P uye S itsvina inokuvadza; mazinga akawandisa anogona kukonzera kuwedzera brittleness, kudhirowa kutyoka, uye kushomeka zinc plating adhesion. Nokudaro, kunyatsoteerera kumiganhu yepamusoro kunokosha.
Mechanical zvivakwa zvinowanzo tarisa nzvimbo dzekushandisa dzeGalvanized Steel Wire. Tinoda simba rekusimba re290 ~ 420MPa, kureba Kukura kupfuura kana kuenzana ne25%, kuderedza nzvimbo Yakakura kupfuura kana yakaenzana ne55%, uye kuoma HRB 60 ~ 75. Waya tsvimbo haifanire kuve nekupatsanurwa kuri pachena, delamination, kana shrinkage cavities; kana zvisina kudaro, inowanzoputsika panguva yekudhirowa uye kuputika kwechigadzirwa chakapedzwa. Vazhinji vashandisi vane zvakaomesesa zvinodiwa zvemhando yepamusoro yeGalvanized Steel Wire. Vagadziri vane hunyanzvi vanofanirwa kuona kuti pasi haina kutsemuka, kupeta, mavanga, maburrs, yakanyanyisa gobvu iron oxide scale, ngura, mavara emafuta, uye tsvina pakubuda mufekitori. Kushivirira kwedhayamita kunofanira kunge kuri ± 0.20mm, uye ellipticity Idiki kana kuenzana ne60% yedhayamita kushivirira. Mitambo yewaya ine ngura yakaoma yepamusoro inorambidzwa kubva pakugadzirwa; kana zvisina kudaro, pickling ichave isina kukwana uye zinc layer adhesion ichava murombo.
Chinangwa chepakati che pretreatment ndechekubvisa oxide chiyero, ngura, uye oiri, kuve nechokwadi chakachena uye chakabatidzwa simbi waya pamusoro kuvimbisa yakanaka metallurgical bond pakati pezinc yakanyungudutswa nesimbi substrate. Kusabatwa zvakanaka panguva yekugadzirwa kweGalvanized Steel Wire kunogona kutungamirira zvakananga kune zinc layer peeling, plating isina kukwana, uye kubuda ruvara.
Degreasing uye mafuta ekubvisa mhando zviyero: Alkali concentration 5% ~ 10%, tembiricha 60 ~ 80 dhigirii, nguva yekurapa 3 ~ 8min. Yekuongorora mwero: Hapana mavara emafuta kana saponification yakasara pane simbi waya pamusoro, inoenderera uye yakafanana firimu remvura, hapana shrinkage cavities.
Acid pickling uye ngura yekubvisa mhando zviyero: Inowanzo shandiswa hydrochloric acid pickling. Kuisa pfungwa, tembiricha, uye nguva zvinofanira kunyatsodzorwa. Hydrochloric acid concentration 12% ~ 18%, tembiricha yekamuri tembiricha ~ 45 dhigirii, nguva 5 ~ 15min. Mushure mekunhonga, pasi panofanira kuva nesirivha yakafumuka{8}yegrey metallic luster, isina oxide scale saridu, uye isina over{9}}corrosion. Kupfuura{11}kuora kunotongwa nechitarisiko chegomba, hydrogen embrittlement, kana kusviba pamusoro; kana yawanikwa, iyo yepamusoro inofanira kuraswa.
Kugezeswa kwemvura: Mushure mekunhonga asidhi, yakawanda-stage countercurrent rinsing inodiwa. Danho rekutanga rinoshandisa mvura yakachena inoyerera kubvisa asidi yemahara. Nhanho yechipiri inoshandisa pH Yakakura kupfuura kana yakaenzana ne4 kudzivirira asidhi kubva mukutakurwa mutangi inoyerera. Yekutarisa chiyero: Hapana asidhi yakasara kana iron munyu inonamatira pamusoro.
Fluenting kurapwa kwemhando zviyero: Flux inowanzova zinc chloride + Iyo ammonium chloride yakasanganiswa mhinduro inoshanda kudzivirira yechipiri oxidation uye kuvandudza kunyorova kweiyo zinc yekugezera. Tinoda kusanganiswa kwe150-250 g/L, tembiricha ye50-70 dhigirii, pH ye4.0-5.5, nguva yekurapa kwemaminetsi 1-3, tembiricha yekuomesa ye120-200 degree, uye nguva yekuomeswa yekuoma kwakazara kwepasi, isina unyoro, mavara emunyu, uye crystallization isina kuenzana. Iyo flux solution inofanirwa kusefa nguva nenguva kubvisa slag; kana zvisina kudaro, zinc slag uye zinc nodules ichaumba, inokanganisa hutano hwepamusoro hweGalvanized Steel Wire.
Galvanizing yakakamurwa kuita kupisa-dip galvanizing neelectro-galvanizing, uye mwero wemhando yezviviri izvi unosiyana zvakanyanya, zvichiita kuti ive chinhu chikuru chekuongorora kutengeserana kwekunze.
Kupisa-kunyura galvanized steel wire quality standards: Kupisa-dip galvanizing results in zinc layer yakakora uye kureba kwekuora, zvinoenderana neISO 1460, ASTM A641, uye GB/T 20492. Raw material zinc ingots i99.99% kusvika 99.99% pure zinc. 440 ~ 465 dhigirii, aruminiyamu yemukati ndeye 0.18% ~ 0.22%, tsvina yekugezesa zinc iri Isingasviki kana kuenzana ne0.02% Fe, uye kushandiswa kwezinc yakadzokororwa kunorambidzwa.
Electro-galvanized steel wire quality standards: Electro-galvanized steel waya ine nzvimbo yakatsetseka uye zinc layer yakatetepa, inokodzera zvigadzirwa zvemazvo. Iyo zinc layer huremu ndeye 10 ~ 40g/m², ukobvu i1.4 ~ 5.6μm, iyo nzvimbo inopenya uye yakafanana, isina kupisa kana kusviba, uye ine yakaderera brittleness, ichiita kuti ive yakakodzera kukotama uye kugadzira. Kusaita ngura kwairi kuita hakuna simba pane kupisa-dip galvanizing, uye haikodzere nzvimbo dzinoita ngura zvakanyanya.
