Patinofunga nezvezvinhu zvemhando yepamusoro, tinowanzo svetukira kune titanium alloys, carbon fiber, kana simbi isingatsvedzeri inopenya. Zvisinei, musimboti wenyika yedu yanhasi wakaderera zvikuru:simbi isina kabhoni. Ichishandiswa pakugadzira simbi pasi rose inosvika 85-90%, chiumbwa ichi ndicho chinhu chinoshandiswa zvakanyanya mumaindasitiri. Asi chii chinoita kuti simbi yekabhoni "isina kuumbwa" ive yakakosha kudaro, uye ndechipi chokwadi chikuru nezvehunhu hwayo?
Kureruka kweAlloy
Izwi rekuti "plain" rinoratidza kuti simbi iyi ine zvinhu zvidiki chete zvinosanganisa simbi. Haina chromium, nickel, kana molybdenum yakawanda, iyo inowanzo wedzerwa kusimbi dzakakosha. Pane kudaro, inenge iri alloy yesimbi nekabhoni. Manganese nesilicon zvishoma zviripo, asi kabhoni inonyanya kudzora hunhu hwesimbi.
Chokwadi chinonyanya kukosha nezvesimbi isina kabhoni ndeyehukama hwakasiyana pakati pesimba uye ductility. Sezvaunowedzera kabhoni, simbi inowedzera kusimba, asi inovawo yakaoma kupwanyika uye yakaoma kusanganisa.
Simba Rakawanda
Mainjiniya anowanzo patsanura simbi isina kabhoni mumapoka matatu zvichienderana ne "siginecha" yavo yekabhoni:
Simbi Yekabhoni Yakaderera (Simbi Isina Kusimba):Iine kabhoni inosvika 0.25%, iyi ndiyo mhando inonyanya kushandiswa. Tinowanzoishandisa pakugadzira mapaneru emotokari nematanda emadziro muzvivako zvakakura. Uye yakakodzera kuvaka kukuru uye kugadzira machubhu esimbi. "Chokwadi" chayo chiri mukusimba kwayo kunoshamisa; unogona kuikombamisa, kuimonyorora, uye kuisundira pasina kuipwanya.
Simbi yeKabhoni Yepakati:Nekabhoni iri pakati pe0.25% kusvika 0.6%, iyi shanduro inoita kuti zvinhu zvienderane. Chigadzirwa ichi chinopa simba rakakwana renjanji nemagiya, zvichibatanidza kuramba kusakara nekukwanisa kutsungirira kudedera kwakasimba pasina kutsemuka.
Simbi yeKabhoni Yakawanda:Kazhinji ine kabhoni iri pakati pe0.6% kusvika pa1.2–1.4%, simbi iyi yakaoma zvikuru. Kushandisa simbi ine kabhoni yakawanda kunoita kuti mapanga ekicheni yako, mabhora ekuboorera, uye masipiringi zvikwanisike. Chigadzirwa chacho chinogara kwenguva yakareba kupfuura simbi isina kusimba. Kupisa kwakakodzera kunodiwa. Pasina kurapwa kwakakodzera, kuomarara kwesimbi kunoderera zvakanyanya.
Kuchinjana: Chinhu Chinokonzera Rust
Chimwe chechokwadi chisingadzivisike nezvesimbi isina kabhoni ndechekuti inogona kukanganiswa nemamiriro ekunze. Simbi isina kabhoni inoumba jira rinodzivirira rechromium oxide. Simbi isina kabhoni haishande zviri nyore neokisijeni nehunyoro. Pasina chifukidziro chinodzivirira—senge pendi, mafuta, kana zinc layer (galvanization)—inozopedzisira yadzokera kumamiriro ayo echisikigo: iron oxide, kana ngura.
Pamashandisirwo ekuvaka, kukosha kwayo kwechokwadi kuri mu:
- Maitiro anofungidzirwa
- Magiredhi akajairika
- Kugadzira zvinobudirira
- Kuwanikwa kwepasi rose
Kubva pamafuremu ekuvaka kusvika kumapaipi esimbi, simbi isina kabhoni inoramba iri gamba risingazivikanwe reinjiniya yemazuva ano yekuvaka.
Nei Zvichiri Kukunda
Sei simbi isina kabhoni ichiri kushandiswa zvakanyanya, pasinei nekuita ngura uye kusasimba zvakanyanya sesimbi dzekunze? Mhinduro yacho ndeyekuchengetedza mari uye kugona kudzokorodza. Simbi isina kabhoni yakachipa zvikuru kugadzira kupfuura chero imwe simbi ine simba rakafanana.
Kuti iwedzere hupenyu hwebasa, mapaipi esimbi anowanzo dzivirirwa ne:
- Kupenda kana kupeta
- Kuisa mafuta ekuchengetedza kwenguva pfupi
- Galvanization (zinc coating) yenzvimbo dzekunze uye dzine hunyoro
Kana paine kugadziriswa kwakakodzera kwenzvimbo, mapaipi esimbi ecarbon anogona kushanda zvakanaka kwemakumi emakore.
Uyezve, ndeimwe yezvinhu zvinoshandiswazve kushandiswazve pasi rose. Danda resimbi rinobva mudura rema1920 rinogona kunyungudutswa roshandiswazve sechasi yemotokari ya2026. Hunhu hwaro hahuna kuchinja.
Mhedziso
Simbi isina kabhoni inoratidza kuti zvinhu zvakaoma kunzwisisa hazvisi nyore nguva dzose mukushandiswa kweinjiniya. Kuchinja kudiki kwehuwandu hwekabhoni musimbi kunogona kugadzira chero chinhu kubva pawaya yakapfava kusvika pakutsigira mabhiriji makuru. Chinhu chinotsanangurwa nekuenzanisa—kuchinjana kuramba ngura kuti zvionekwe kuti zviri nyore kutenga, uye kugona kusimba.
