Kupisa-kunyikainzira inoshandiswa zvakanyanya yekudzivirira simbi nesimbi kubva mukuora. Maitiro aya anosanganisira kunyudza simbi mubhavhu rezinc yakanyungudutswa, iyo inoumba coating yakasimba, inodzivirira. Simbi inobuda mu galvanized inodzivirira zvikuru ngura uye inogona kutsungirira mamiriro ekunze akaoma. Zvisinei, kuwana mhedzisiro yakanaka kunoda kutevedzera zvinodiwa chaizvo uye maitiro akanakisa. Chinyorwa chino chinotarisa zvinodiwa zvakakosha zve hot-dip galvanizing kuti ive nechokwadi chekuti mhedzisiro yacho ndeyemhando yepamusoro uye inogara kwenguva refu.
1. Kusarudzwa Kwezvinhu
Chinodiwa chekutanga pakupinza simbi mumoto ndiko kusarudza zvinhu zvakakodzera. Hadzisi simbi dzese dzakakodzera kuita izvi. Kazhinji, simbi nesimbi ndizvo zvinonyanya kukosha. Kuumbwa kwesimbi kunogona kukanganisa zvikuru kunaka kwesimbi.galvanizingSemuenzaniso, kuvapo kwezvinhu zvakaita sesilicon nephosphorus musimbi kunogona kukanganisa ukobvu uye chitarisiko chezinc coating. Saka, zvakakosha kusarudza zvinhu zvine magadzirirwo akadzorwa uye anozivikanwa kuti uwane mhedzisiro yakafanana.
2. Kugadzirira Pamusoro
Kugadzirira pamusoro pevhu idanho rakakosha mukunyudza nekupisamaitiro acho. Pamusoro pesimbi panofanira kunge pakachena uye pasina zvinhu zvinosvibisa zvakaita semafuta, mafuta, ngura, uye chikero chemugayo. Chero tsvina inogona kudzivirira zinc kunamira zvakanaka, zvichiita kuti coating isashande zvakanaka. Kugadzirira pamusoro kunowanzoita matanho matatu:
- Kubvisa mafuta: Kubvisa tsvina yemuchadenga uchishandisa mishonga yealkaline kana zvinonyungudutsa.
- Kubvisa ngura: Kubvisa ngura nemakwande uchishandisa mishonga ine acidic, kazhinji hydrochloric kana sulfuric acid.
- Kusvina: Kushandiswa kwemvura inoyerera, kazhinji zinc ammonium chloride, kudzivirira oxidation isati yanyudzwa mu zinc yakanyungudutswa.
Kugadzirira zvakanaka pamusoro pechinhu kunoita kuti simbi ne zinc coating zvive zvakabatana, zvichiita kuti galvanizing igare kwenguva refu uye ishande zvakanaka.
3. Kuumbwa kweBath uye Tembiricha
Kuumbwa uye tembiricha yebhavhu rezinc zvinhu zvakakosha mukuita kwekupisa-kudipu. Bhavhu rezinc rinofanira kunge riine zinc yakachena inosvika 98%, uye chikamu chasara chinosanganisira zvinhu zvakaita sealuminium, lead, uye antimony kuti zvivandudze hunhu hwebhavhu. Tembiricha yebhavhu inowanzova pakati pe820°F ne860°F (438°C kusvika 460°C). Kuchengetedza tembiricha chaiyo kwakakosha kuti pave nependi yakaenzana uye yepamusoro. Kutsauka kunogona kukonzera zvikanganiso zvakaita seukobvu husina kuenzana, kunamira kusina kunaka, uye kusasimba kwepamusoro.
4. Nguva Yokunyudzwa
Nguva yekunyudzwa mubhavhu rezinc ndeimwe nzira inokosha. Zvinoenderana nekukora uye saizi yebhavhu.simbi iri kugayiwaKazhinji, simbi inonyudzwa kusvika yasvika patembiricha yekugezera, zvichibvumira zinc kuumba chisungo chesimbi nesimbi. Kunyudzwa zvakanyanya kunogona kukonzera ukobvu hwekuvhara zvakanyanya, nepo kunyudzwa zvishoma kunogona kukonzera dziviriro isina kukwana. Nokudaro, kudzora nguva yekunyudzwa kwakakodzera kunodiwa kuti uwane ukobvu hwekuvhara hunodiwa uye hunhu.
5. Kurapwa Mushure meKushandisa Magetsi
Mushure mekunge simbi yabviswa kubvakugeza ne zinc, inorapwa mushure mekugadziriswa kwesimbi kuti iwedzere kunaka kwesimbi. Kurapa uku kunogona kusanganisira kudzima mumvura kana kutonhodza mhepo kuti zinc coating irambe yakasimba nekukurumidza. Pamusoro pezvo, kurapwa kwepasi kunogona kushandiswa kudzivirira kuumbwa kwengura chena, rudzi rwengura inogona kuitika panzvimbo dzakagadzirwa nesimbi. Kubata nekuchengetedza zvinhu zvakagadziriswa nesimbi kwakakoshawo kuti simbi irambe yakasimba.
6. Kuongorora uye Kudzora Hunhu
Chekupedzisira, kuongorora kwakakwana uye kudzora mhando kwakakosha kuti kuve nechokwadi chekubudirira kwekunyudza nekupisamaitiro. Kuongorora kunowanzo sanganisira kuongorora kwemaziso, kuyera ukobvu, uye bvunzo dzekunamatira. Mitemo yakaita seASTM A123/A123M inopa gwara rekuti coating coating coating coating coating coating coating coating coating coating coating coating coating coating procedures. Kutevedzera mitemo iyi kunoita kuti zvigadzirwa zve galvanized zvisvike pazvinodiwa uye zvinopa dziviriro inogara kwenguva refu kubva mukuora.
Mhedziso
Kuisa magaroni mudhibhi rinopisa inzira inoshanda yekudzivirira simbi nesimbi kubva mukuora, asi zvinoda kunyatsotarisisa zvakadzama uye kutevedzera zvinodiwa chaizvo. Kubva pakusarudza zvinhu uye kugadzirira pamusoro kusvika pakuumbwa kwebhavhu, nguva yekunyudza, uye kurapwa mushure mekuisa magaroni, danho rega rega rinoita basa rakakosha mukuwana magaroni emhando yepamusoro uye anogara kwenguva refu. Nekutevera maitiro aya akanakisa uye kuchengetedza kudzora kwemhando, vagadziri vanogona kuve nechokwadi chekuti zvigadzirwa zvavo zvegaroni zvinopa kushanda kwakanaka uye kurarama kwenguva refu.
