Kupisa-dip galvanizinginzira inoshandiswa zvakanyanya kuchengetedza simbi nesimbi kubva mukuora. Izvi zvinosanganisira kunyudza simbi mubhati rezinc yakanyungudutswa, iyo inoumba yakasimba, inodzivirira. Simbi inokonzeresa inoshingirira kuita ngura uye inokwanisa kumira nemamiriro ekunze akaomarara. Nekudaro, kuwana mhedzisiro yakanaka kunoda kuteedzera kune chaiyo zvinodiwa uye maitiro akanaka. Ichi chinyorwa chinotarisa mune zvakakosha zvinodikanwa zvekupisa-dip galvanizing kuti ive nechokwadi chemhando yepamusoro uye yakasimba mibairo.
1. Kusarudzwa kwezvinhu
Chinodiwa chekutanga chekupisa-dip galvanizing ndiko kusarudzwa kwezvinhu zvakakodzera. Haasi ese masimbi akakodzera muitiro uyu. Kazhinji, simbi nesimbi ndizvo zvinonyanya kukwikwidza. Kuumbwa kwesimbi kunogona kukanganisa zvakanyanya kunaka kwegalvanizing. Semuenzaniso, kuvapo kwezvinhu zvakaita sesilicon uye phosphorus musimbi kunogona kukanganisa ukobvu uye kutaridzika kweiyo zinc coating. Naizvozvo, zvakakosha kuti usarudze zvinhu zvine anodzorwa uye anozivikanwa maumbirwo kuti uwane mhedzisiro inowirirana.
2. Kugadzirira Kwepamusoro
Kugadzirira kwepamusoro inhanho yakakosha muinopisa-dip galvanizingprocess. Nzvimbo yesimbi inofanirwa kuve yakachena uye isina zvinosvibisa zvakaita semafuta, girisi, ngura, uye chigayo. Chero tsvina inogona kudzivirira zinc kubva pakunamatira zvakanaka, zvichitungamira kuhurombo hwekuputira kunaka. Kugadzirira kwepamusoro kunowanzobatanidza matanho matatu:
- Degreasing: Kubvisa organic contaminants uchishandisa alkaline solution kana solvents.
- Pickling: Kubvisa ngura nechikero uchishandisa acidic solution, kazhinji hydrochloric kana sulfuric acid.
- Fluxing: Kushandiswa kwemushonga weflux, kazhinji zinc ammonium chloride, kudzivirira oxidation isati yanyudzwa mu zinc yakanyungudutswa.
Kugadzirira kwakakodzera kwepamusoro kunovimbisa chisungo chakasimba pakati pesimbi uye zinc coating, kuwedzera kusimba uye kushanda kwe galvanizing.
3. Bath Kuumbwa uye Tembiricha
Kuumbwa uye tembiricha yekugezera zinc zvinhu zvakakosha mukupisa-dip galvanizing process. Iyo zinc yekugezera inofanirwa kunge iine 98% pure zinc, ine chikamu chasara chinosanganisira zvinhu zvakaita sealuminium, lead, uye antimony kuvandudza zvimiro zvejasi. Tembiricha yekugezera inowanzosiyana pakati pe820°F ne860°F (438°C kusvika 460°C). Kuchengetedza tembiricha yakakodzera kwakakosha kuti uwane yunifomu uye yemhando yepamusoro coating. Kutsauka kunogona kukonzera kukanganisa senge kusaenzana ukobvu, kusanamatira zvakanaka, uye kushata kwepamusoro.
4. Nguva Yokunyudzwa
Nguva yekunyudzwa mubhati zinc ndiyo imwe yakakosha parameter. Izvo zvinoenderana nekukora uye saizi yesimbi iri kurashwa. Kazhinji, simbi inonyudzwa kusvika yasvika pakudziya kwekugezera, zvichiita kuti zinc iite chisungo chesimbi nesimbi. Kunyudza zvakanyanya kunogona kutungamira mukukobvu kwekuputira, nepo kunyudzwa-pasi kunogona kukonzera kuchengetedzwa kwakaringana. Naizvozvo, kunyatso kudzora nguva yekunyudzwa kunodiwa kuti uwane inodiwa yekuputira ukobvu uye mhando.
5. Post-Galvanizing Kurapa
Mushure mekunge simbi yabviswa kubva kuzinc kugeza, inoitwa post-galvanizing treatments kuti iwedzere kunaka kwekuputira. Mishonga iyi inogona kusanganisira kudzima mumvura kana kutonhora kwemhepo kuomesa zinc coating nekukurumidza. Pamusoro pezvo, marapirwo ekupasa anogona kushandiswa kudzivirira kuumbwa kwegora chena, rudzi rwekuora kunogona kuitika panzvimbo ichangobva kuputirwa. Kubata kwakanaka uye kuchengetwa kwezvinhu zvine galvanized zvakakoshawo kuchengetedza kutendeseka kwejasi.
6. Kuongorora uye Kudzora Kwehutano
Chekupedzisira, kunyatsoongorora uye kutonga kwemhando kwakakosha kuti uve nechokwadi chekubudirira kweiyoinopisa-dip galvanizingprocess. Kuongorora kunowanzo sanganisira kuongororwa kwekuona, kuyerwa kwehukobvu, uye bvunzo dzekunamatira. Zviyero zvakaita seASTM A123/A123M zvinopa nhungamiro yeukobvu hwekuputira hunogamuchirwa uye hunhu. Kuomerera kune aya zviyero kunovimbisa kuti zvigadzirwa zvemarara zvinosangana nezvinodiwa maitiro uye zvinopa dziviriro yenguva refu kubva mukuora.
Mhedziso
Kupisa-dip galvanizing inzira inoshanda yekudzivirira simbi nesimbi kubva mukuora, asi inoda kunyatsotarisisa kune zvakadzama uye kutevedzera kune zvakati zvinodiwa. Kubva pakusarudzwa kwezvinhu uye kugadzirira kwepamusoro kusvika pakuumbwa kwekugezera, nguva yekunyudzwa, uye marapirwo epashure-kupfuta, nhanho imwe neimwe inoita basa rakakosha mukuwana mabhati emhando yepamusoro uye akasimba. Nekutevedzera aya akanakisa maitiro uye nekuchengetedza kusimba kwehutongi hwemhando, vagadziri vanogona kuona kuti zvigadzirwa zvavo zvemagetsi zvinounza kuita kwakaringana uye hupenyu hurefu.
