Nhanganyaya kuwsimbi yekudyamterevhizheni
Simbi inonyungudika, kureva simbi inodzivirira ngura mumhepo, isimbi ine alloy yakaderera pakati pesimbi yakajairika nesimbi isina ngura. Simbi inonyungudika inogadzirwa nesimbi yakajairika ine zvinhu zvishoma zvinodzivirira ngura zvakaita semhangura nenickel. Ine hunhu hwesimbi yemhando yepamusoro, senge kusimba, kureba kwepurasitiki, kuumba, kusveta, kucheka, kukwesha, kupisa kwakanyanya, kuramba kuneta, nezvimwewo; Kuramba kwemamiriro ekunze kwakapetwa kaviri kusvika kasere pane simbi yakajairika yekabhoni, uye kuramba kuputira kwakapetwa ka1.5-10 pane simbi yakajairika yekabhoni. Panguva imwe chete, ine hunhu hwekudzivirira ngura, kuramba ngura, kuwedzera hupenyu hwezvikamu, kuderedza ukobvu nekushandiswa, uye kuchengetedza basa nesimba.
Pmashandiro uye hunhuyesimbi inogadzirisa mamiriro ekunze
Simbi yeWeathering yakabva kuCorten Steel kuNorth America, uye inoshandiswa zvakanyanya mukugadzira ngoro dzechitima, makontena nemabhiriji; Simbi yeWeathering inoshandiswa sezvinhu zvekuvaka, iyo ine nhoroondo yakati muNorth America, Western Europe, Australia, Japan neSouth Korea muAsia. Nekuwedzera mhangura, chromium, nickel nezvimwe zvinhu zveWeathering kusimbi yeWeathering, jira reinenge 50~100 rinoumbwa pakati pejira rengura ne substrate μ. Rakakora re dense oxide rine ukobvu hwe m uye rinonamatira zvakanaka kusimbi yepasi. Rakakora iri re dense oxide rine ruvara rutsvuku rwengura rwechisikigo rwakasimba uye rwakafanana.
1. Hunhu hwakasiyana hwekushanda: Chekutanga, ine kutaridzika kwakanaka kwazvo. Mapureti esimbi ane ngura anochinja nekufamba kwenguva. Kupenya kweruvara rwayo uye kuwanda kwayo kwakakwira kupfuura zvinhu zvekuvaka zvakajairika, saka zviri nyore kuoneka kana yakasvibirira mubindu. Pamusoro pezvo, pamusoro pevhu rakaomarara rinokonzerwa nengura yepureti yesimbi inoita kuti chivakwa chacho chive chakawanda uye chemhando yepamusoro.
2. Ine kugona kwakasimba kwekuumba. Kufanana nezvimwe zvinhu zvesimbi, mapurati esimbi ane ngura ari nyore kugadzira kuita maumbirwo akasiyana-siyana uye anochengetedza kunaka kwayo, izvo zvinonetsa kuti matanda, matombo, nekongiri zviwanikwe.
3. Ine kugona kwakasiyana kwekuona nzvimbo. Nekuda kwekusimba uye kusimba kwemaplate esimbi, hapana miganho yakawanda yekukora sezvidhinha nematombo nekuda kwemaumbirwo awo. Saka, maplate esimbi akatetepa anogona kushandiswa kupatsanura nzvimbo zvakajeka uye nemazvo, zvichiita kuti nzvimbo yacho ive pfupi, ine hupenyu, uye izere nesimba.
Maitiro ekurapa ngurayesimbi inogadzirisa mamiriro ekunze:
Nzira yekurapa ngura ndeyekushandisa nzira dzemakemikari (mhinduro yengura) pamusoro pesimbi inodzivirira ngura kuti igadzire firimu rakagadzikana. Inzira yekudzivirira ngura inobuda panguva yekutanga kushandisa simbi uye kuita kuti igare yakasimba. Kugadzirisa nemaoko kunowanzotora mazuva makumi matatu. Kazhinji, kana kurapwa kwependero kukakuvara zvishoma, kuchaita kuti pendero ibviswe, zvichikonzera ngura. Kuti kuchengetedze runako, zvinodikanwa kupenda patsva. Zvisinei, nzira yekurapa ngura inosanganisira kunyungudutsa firimu rengura zvishoma nezvishoma, kuwedzera zvishoma nezvishoma ngura inobuda pamusoro pese, uye kufukidza simbi nefirimu rengura pasina kugadzirisa.
1. Danho rekutanga: simbi chaiyo yakatanga kukura zvidimbu zvidiki zvengura. Zvidimbu zvengura zvemaplate esimbi akajairwa zvakanga zvisina kusimba, uye zvimwe zvacho zvakanga zvisina kurapwa zvakanaka kwengura uye zvaitova nemakwande engura;
3. Danho rechipiri resimbi ngura refu: simbi chaiyo inonaya mvura ine ngura shoma, uye ngura dziri muzvidimbu zvidiki uye dzakakora; Maplate esimbi akajairwa ane ngura yakawanda, ane ngura dzakakura uye dzakatetepa; Mhete dzengura nemavanga ekubvaruka pamaplate esimbi akajairwa zvakanyanya, uye pane zviratidzo zvekusviba pasi pebasa;
4. Danho rechitatu resimbi ine ngura refu: simbi chaiyo ine ngura yakajeka uye yakakora, uye mavanga engura anonamirwa zvakanyanya kuti agadzire jira rinodzivirira, risingakwanise kubviswa nemaoko; Maplate esimbi akajairwa ane ngura yakawanda, uye kunyange chidimbu chose chengura chinobviswa uye chinopera. Simbi chaiyo ine tsvuku yebrown, nepo plate yesimbi yakajairwa ine dema dema.
Nzvimbo dzekuvaka nekuisa
Kuiswa kwemadziro emaketeni esimbi yekuvaka simbi inodziya (3MM) kwakafanana nemadziro ekunze ealuminium plate pari zvino. Matanda emaketeni esimbi anodziya (5MM zvichikwira) anodzivirira mamiriro ekunze anowanzo shandiswa senzira yekurembera yekunze. Nzvimbo nezvimwe zvishandiso zviri nyore zvinowanzo shandisa tekinoroji yekuwelda zvakananga. Zvinhu zvinotevera zvinofanira kucherechedzwa:
1. Kuora kwenzvimbo dzekuwelding: Mwero weoxidation wenzvimbo dzekuwelding unofanirwa kunge wakafanana nezvimwe zvinhu zvinoshandiswa, izvo zvinoda zvinhu zvewelding nematekiniki akakosha.
2. Kuora kwemvura: simbi inonyungudutsa haisi simbi isina ngura. Kana paine mvura iri panzvimbo yakakombama yesimbi inonyungudutsa, ngura yacho inokurumidza, saka mvura inofanira kuyerera zvakanaka.
3. Nzvimbo ine mhepo ine munyu: simbi inotonhora inonzwa mhepo ine munyu yakawanda seHawaii. Munzvimbo yakadaro, firimu rekudzivirira pamusoro rinogona kusadzivirira kuoxidation kwemukati.
4. Kuchinja ruvara: Rutivi rwengura pamusoro pesimbi inodonha inogona kuita kuti pamusoro pezvinhu zviri pedyo nayo pave nengura.
Mutengo wepakati
Mutengo wesimbi inonyungudutsa yakaora unosanganisira mutengo wesimbi ine ngura uye mutengo wekugadzirisa ngura. Kugadzirisa ngura kunosiyana kubva pa100 kusvika 400 RMB pa square meter zvichienderana nemaitiro acho. Simbi inonyungudutsa yakaonda inosvika 4600 RMB/tani. Tichitora simbi ine 3MM gobvu inodzivirira mamiriro ekunze semuenzaniso, zvinhu zvakacheneswa zvinosvika 120RMB/m2, uye madziro eketeni anenge 500RMB/m2mushure mekugadzirisa ngura uye kuisa jira rinopetwa.
