Bhiriji rakabatidzwa, rinozivikanwawo sebhiriji rakabatidzwa remagetsi; Kazhinji rinonzwisiswa sebhiriji rakabatidzwa iro riri bhiriji rakabatidzwa rinopisa, kutaura chokwadi, hazvina kunaka, sepombi yakabatidzwa, bhiriji rakabatidzwa rakakamurwa kuita mhando mbiri, dzinoti, rakabatidzwa rinotonhora (rakabatidzwa remagetsi) uye rakabatidzwa rinopisa (rakabatidzwa rinopisa);
Simbi nesimbi zvinopera ngura zviri nyore mumhepo, mumvura kana muvhu, kana kutokuvara zvachose. Kurasikirwa kwesimbi pagore kunokonzerwa nengura kunoumba chikamu chimwe chete mugumi chesimbi yese inobuda. Kune rumwe rutivi, kuti zvigadzirwa zvesimbi nezvikamu zvive nebasa rakakosha pamusoro, uye zvinoita kuti pamusoro payo pave nechitarisiko chekushongedza panguva imwe chete, saka inowanzo shandiswa semagetsi.
1. Nheyo:
Nekuti zinc haisi nyore kuchinja mumhepo yakaoma, uye mumhepo ine hunyoro, pamusoro payo panogona kuumba firimu rezinc carbonate rakakora, firimu iri rinogona kudzivirira mukati kubva mukuora. Uye kana chifukidziro chikakuvara nechikonzero chakati uye hwaro hwesimbi husina kukura zvakanyanya, zinc nesimbi zvinoumba microbattery, zvekuti simbi inova cathode uye inodzivirirwa.
2. Hunhu hweKushanda:
1) Zinc coating yakakora, crystallization yakanaka, yakafanana uye haina maburi, uye kuramba ngura kwakanaka;
2) Zinc layer inowanikwa ne electroplating yakachena uye inoora zvishoma nezvishoma mu acid ne alkali fog, izvo zvinogona kudzivirira matrix yesimbi zvinobudirira;
3) Zinc coating inoumbwa ne chromic acid passivation chena, ruvara, girini yemauto, yakanaka, ine imwe yekushongedza;
4) Nekuti zinc coating ine ductility yakanaka, inogona kutonhora blanking, kutenderedza, kukotama uye zvimwe zvinoumba pasina kukuvadza coating.
3. Chiyero chekushandisa:
Nekukura kwesainzi netekinoroji, indasitiri ye electroplating inosanganisira minda yakakura. Parizvino, kushandiswa kwe galvanizing kwave kuri kuitwa mumadhipatimendi ekugadzira nekutsvagisa ehupfumi hwenyika. Semuenzaniso, kugadzira michina, zvemagetsi, zvekushandisa pakugadzira, indasitiri yemakemikari, indasitiri yechiedza, zvekufambisa, zvombo, zvemuchadenga, simba reatomu, nezvimwewo, zvakakosha zvikuru muhupfumi hwenyika.
Bhiriji rakabatidzwa nekupisa(bhiriji rezinki rinopisa)
1, tsananguro ye zinc inopisa:
Zinc inopisa ndiyo imwe yenzira dzakanakisisa dzekuputira simbi. Iri muchimiro chemvura chezinc, mushure mekushanda kwakaoma uye kwemakemikari, kwete chete pasimbi yakakora yezinc, asiwo inogadzira zinc-iron alloy layer. Iyi nzira yekuputira haina chete hunhu hwekudzivirira ngura yegalvanizing, asiwo ine zinc-iron alloy layer. Inewo simba rekudzivirira ngura risingaenzaniswi negalvanizing. Saka, iyi nzira yekuputira inonyanya kukodzera mhando dzese dzeasidhi yakasimba, alkali fog nedzimwe nzvimbo dzakasimba dzekuputira ngura.
2. Nheyo:
Zinc layer inogadzirwa nematanho matatu pasi pemvura inopisa zvakanyanya:
1) Pamusoro pesimbi inonyungudutswa ne zinc solution kuti igadzire zinc-iron alloy phase layer;
2) Maion ezinc ari muchikamu chealloy anopararira zvakanyanya ku matrix kuti agadzire chikamu chinosanganiswa ne zinc-iron;
3) Pamusoro pechikamu che alloy chakapoteredza chikamu che zinc.
3. Hunhu hwekushanda:
(1) Nezinc yakakora yakafukidza pamusoro pesimbi, inogona kudzivirira matrix yesimbi uye chero mhinduro yekuora, kudzivirira matrix yesimbi kubva mukuora. Mumhepo yakajairika, pamusoro pezinc layer inoumba pamusoro pezinc oxide yakatetepa uye yakakora, zvakaoma kunyunguduka mumvura, saka inoita basa rekudzivirira pasimbi. Kana zinc oxide nezvimwe zvikamu zviri mumhepo zvikagadzira munyu wezinc usinganyungudike, dziviriro yekuora inonyanya kunaka.
(2) Kune simbi-zinc alloy layer, diki, mumhepo yemvura inopfapfaidza munyu uye mumhepo yeindasitiri ine simba rekudzivirira ngura;
(3) Nekuda kwekubatana kwakasimba, zinc-iron inogona kusanganiswa, uye inodzivirira kupfekwa zvakanyanya;
(4) Nekuti zinc ine ductility yakanaka, alloy layer yayo uye simbi yakabatana zvakasimba, saka zvikamu zvinopisa zvinogona kutonhora kudzvanya, kutenderedza, kudhirowa, kukotama nezvimwe mafomu pasina kukuvadza coating;
(5) Mushure mekunyudza zvikamu zvesimbi nekupisa, zvinoenzana nekushandisa imwe chete yekuwedzera simba resimbi, izvo zvinogona kuvandudza mashandiro esimbi, kubvisa kushushikana panguva yekuumbwa nekusungirirwa kwezvikamu zvesimbi, uye zvinobatsira pakutenderedza zvikamu zvesimbi.
(6) Pamusoro pezvishongedzo mushure mekunyudzwa nekupisa kwakachena uye kwakanaka.
(7) Zinc layer yakachena ndiyo purasitiki yakanyanya kupfava ye hot dip galvanized layer, hunhu hwayo hwakafanana ne zinc yakachena, ductility, saka inochinjika.
4. Chiyero chekushandisa:
Kushandiswa kwe "hot dip galvanizing" kunowedzera nekukura kwemaindasitiri nekurima. Nokudaro, zvigadzirwa zve "hot-dip galvanizing" muindasitiri (zvakadai semidziyo yemakemikari, kugadzira peturu, kutsvaga marine, chimiro chesimbi, kutumirwa kwesimba, kuvaka ngarava, nezvimwewo), kurima (zvakadai se: kudiridza, greenhouse), kuvaka (zvakadai se: kutumirwa kwemvura negasi, waya, scaffolding, dzimba, mabhiriji, kutakurwa, nezvimwewo), zvave zvichishandiswa zvakanyanya mumakore achangopfuura. Zvigadzirwa zve "hot-dip galvanizing" zviri kushandiswa zvakanyanya nekuda kwechitarisiko chazvo chakanaka uye kuramba ngura zvakanaka.
Chechipiri, musiyano uripo pakatizambuko rekupfapfaidzauyezambuko remagaraji
Bhiriji rekupfapfaidza nebhiriji rakabatidzwa zvakasiyana chete pakushanda, marongero, mamodheru, chimiro uye maumbirwo ebhiriji zvakafanana.
Musiyano wemaitiro uripo pakati pepurasiti yepurasiti nepurasiti yegalvanized:
Kutanga kwazvose,zambuko remagarajiuye bhiriji rekupfapfaidza repurasitiki ndere bhiriji resimbi, bhiriji rakabatidzwa rakagadzirwa neplate yesimbi yakabatidzwa, ndiro yakabatidzwa ndinotenda kuti hapana chikonzero chekutsanangura zvakawanda, uye bhiriji rekupfapfaidza repurasitiki rinoshandiswa kugadzirisa jira rekupfapfaidza remagetsi pamusoro pebhiriji rakabatidzwa, saka rinonzi bhiriji rekupfapfaidza repurasitiki, kunzwisisa kuri nyore ndekwekuti bhiriji rekupfapfaidza repurasitiki ndiro shanduro yekuvandudza bhiriji rakabatidzwa, kuramba ngura kwakasimba.
Kana uchifarira chigadzirwa ichi, unogona kudzvanya kona yepazasi kurudyi, tichakubata nekukurumidza.
