Simbi neSimbi Isina Zvisimbiso Zvakafanana Uye Zvakasiyana Sei?

Simbi ndeimwe yezvinhu zvakakosha zvikuru muindasitiri yemazuva ano, ichiumba musimboti wekuvaka, kutakurwa, kugadzirwa, uye mashandisirwo akawanda. Simbi isina ngura, chikamu chesimbi, yakakosha zvakaenzana, kunyanya munzvimbo umo kuramba ngura, hutsanana, uye kugara kwenguva refu zvakakosha. Kunyange zvazvo zvinhu zvose zvakafanana, zvakasiyanawo mukugadzirwa, hunhu, uye mashandisirwo.

Kune mainjiniya, nyanzvi dzekutenga, nevagadziri, kunzwisisa kuti simbi nesimbi isina ngura zvakafanana uye zvakasiyana sei kwakakosha pakusarudza zvinhu zvakakodzera pabasa rega rega.

Chii chinonzi Simbi?

Simbi isimbi inoumbwa nesimbi nekabhoni. Nekugadzirisa huwandu hwekabhoni uye kuwedzera zvimwe zvinhu, vagadziri vanogona kugadzira simbi dzine hunhu hwakasiyana-siyana hwakadai sekuoma, simba, uye ductility.

Mhando dzeSimbi

• Simbi yeKabhoni: Ine simbi nekabhoni zvakanyanya, kubva kune simbi isina kabhoni yakawanda (simbi isina kabhoni yakawanda) kusvika kune mhando dzine kabhoni yakawanda.

• Simbi yeAlloy: Inosanganisira zvimwe zvinhu zvakaita sechromium, nickel, molybdenum, kana vanadium kuti iwedzere kusimba uye kusimba.

• Simbi Yekushandisa: Yakagadzirirwa kuomarara uye kusakara, inowanzoshandiswa mukucheka nekugadzira maturusi.

• Simbi Yekuvaka: Inoshandiswa pakuvaka matanda, makoramu, uye mafuremu.

Chii chinonzi Stainless Steel?

Simbi isina ngura imhando yesimbi yakasarudzika ine10.5% chromiumnehuremu. Chromium inosangana neokisijeni iri mumhepo kuti igadzire chromium oxide yakatetepa pamusoro, inozivikanwa se passive film. Iyi firimu inodzivirira simbi kubva kungura nekuora, zvichiita kuti simbi isina ngura ive yakasiyana kana ichienzaniswa nesimbi dzekabhoni nedze alloy.

Mhando Dzakajairika dzeSimbi Isina Zvisimbiso

• Simbi Isina Kugayiwa yeAustenitic (304, 316): Haipindi ngura zvakanyanya, yakanakira kushandiswa kwechikafu, mugungwa, uye mumakemikari.

• Simbi Isina Kugadzirwa neFerritic (430): Mutengo wakaderera, kuramba kwakanaka kwekupwanyika kwengura.

• Simbi Isina Kugadzirwa yeMartensitic (410, 420): Simba guru uye kuomarara, zvinowanzoshandiswa mumidziyo yekucheka nemidziyo yekuvhiya.

• Simbi Isina Kusimba Duplex (2205, 2507): Inosanganisa simba nekusagona kwe chloride zvakanyanya.

Kufanana Pakati Pesimbi Nesimbi Isina Zvisimbiso

1. Kuumbwa Kwehwaro

Ose ari maviri anonyanya kugadzirwa nesimbi, zvichiita kuti ave alloys yesimbi ine zvimwe zvinhu zvekuvandudza hunhu hwayo.

2. Kuchinja-chinja

Simbi nesimbi isina ngura zvinogona kugadzirwa kuita machira, maplate, mabhawa, mapaipi, uye zvinhu zvinoshandiswa mumaindasitiri akasiyana-siyana.

3. Kugona Kudzokorodza

Zvese zviri zviviri zvinhu zvinogona kudzokororwa zvakanyanya, zvichitsigira zvirongwa zvekuchengetedza nharaunda pasi rose.

4. Simba

Zvese zvinopa simba rakanaka zvichienzaniswa nezvinhu zvisiri zvesimbi, zvichiita kuti zvive zvakanaka pakushandiswa kwechivakwa uye michina.

Kusiyana Pakati Pesimbi Nesimbi Isina Zvisimbiso

1. Kuramba Kuora

Ndeipi Yaunofanira Kusarudza?

Sarudza Simbi Kana:

• Chirongwa ichi chinokoshesa mari.

• Kudzivirira ngura haisi nyaya huru.

• Kuvaka kwakasimba kana michina ndiyo inonyanya kukoshesa.

Sarudza Simbi Isina Kushanda Kana:

• Kudzivirira ngura kunodiwa.

• Utsanana uye kuchena zvakakosha.

• Chirongwa ichi chinosanganisira nzvimbo dzemugungwa kana dzemakemikari.

• Chigadziko chakakwenenzverwa uye chinoyevedza chinodiwa.

Mitemo yeIndasitiri

Zvese zvigadzirwa zvesimbi nesimbi isina ngura zvinofanirwa kutevedzera mitemo yepasi rose yekuchengetedza uye kushanda zvakanaka:

• ASTM(American Society for Testing and Materials).

• ASME(American Society of Mechanical Engineers).

• EN/DIN(Zviyero zveEurope).

• ISO(Sangano Renyika Dzepasi Pose Rekuyera Mamiriro Ezvinhu).

Mitemo iyi inoita kuti simbi nesimbi isingatsvi ikwane simba rinodiwa, kuramba ngura, uye kugara kwenguva refu.

Mafambiro Emangwana

Maindasitiri esimbi nesimbi isina ngura ari kuchinja kuti akwanise kusangana nezvinodiwa zvitsva pasi rose:

• Simbi yegirini: Nzira dzekugadzira dzinoderedza kuburitswa kwekabhoni.

• MaAlloys Epamusoro: Magiredhi akavandudzwa enzvimbo dzakanyanya.

• Zvinhu Zvakangwara: Kuiswa kwemasensa musimbi isingasvibi kuti aonekwe.

• Hupfumi Hwakatenderera: Maitiro ekuvandudza kudzokorodza uye kushandisazve zvinhu.

Zvitsva izvi zvichawedzera kushandiswa kwesimbi nesimbi isingatsvi mukushandiswa kwemazuva ano.

Mhedziso

Simbi nesimbi isina ngura zvakafanana zvakawanda, zvinosanganisira simba, kugona kudzokorodza, uye kushanduka-shanduka kwezvinhu. Zvisinei, zvakasiyana zvakanyanya mukudzivirira ngura, mutengo, chitarisiko, uye mashandisirwo azvo. Simbi inoshanda zvishoma uye inoshandiswa zvakanyanya mukuvaka nemumichina, nepo simbi isina ngura ichikosha mumaindasitiri anoda kugara kwenguva refu, hutsanana, uye kuramba nharaunda dzakaoma.

Kune vagadziri nemainjiniya, sarudzo pakati pesimbi nesimbi isingatsvi inoenderana nezvinodiwa papurojekiti, mamiriro ekunze, uye bhajeti.

Semutengesi wepasi rose wezvigadzirwa zvesimbi isina ngura uye alloy,sakysteelinopa zvinhu zvemhando yepamusoro zvinosangana nezvinodiwa nevatengi pasi rose. Nekuzvipira kuzvinhu zvitsva uye kuvimbika,sakysteelinotsigira maindasitiri pasi rose mukusarudza zvinhu zvakakodzera zvekushandisa kwega kwega.

Nekunzwisisa kuti simbi nesimbi isina ngura zvakafanana uye zvakasiyana sei, mabhizinesi anogona kuita sarudzo dzakavimbika dzinovimbisa kuchengetedzeka, kushanda zvakanaka, uye kubudirira kwenguva refu.
