Ongororo Yezvinhu Zvikuru zveMenduru: Kubva kuMasimbi echinyakare kuenda kuzvinhu zvitsva
Siya meseji
Sezviratidzo zverukudzo, kusarudzwa kwezvinhu zvemenduru hakungoratidzi huremu hwemubairo chete, asiwo kunoratidza kufambira mberi kwehunyanzvi uye kunaka kwenguva. Kubva panguva dzekare kusvika parizvino, zvinhu zvekutanga zvemenduru zvakashanduka kubva kune imwe simbi kuenda kune akawanda akaumbwa zvinhu, imwe neimwe ichizadza menduru ine kukosha kwakasiyana uye kukosha.
The Traditional Three-Gold System of Gold, Silver, and Bronze
Mumitambo yemazuva ano yemitambo uye zviitiko zvikuru, goridhe, sirivheri, uye bhuronzi ndizvo zvinonyanya kuzivikanwa menduru masisitimu. Mazita avo anotorwa zvakananga kubva kune avo ekutanga zvinhu: goridhe, sirivha, uye mhangura. Menduru dzegoridhe dzinowanzo shongedzwa, nepakati pesirivheri yakafukidzwa negoridhe chairo. Sangano reInternational Olympic Committee rinoti goridhe rinenge riri mumenduru yegoridhe harifanire kunge riri pasi pemagiramu matanhatu. Menduru dzeSirivheri dzinonyanya kugadzirwa ne925 sirivheri kana yakakwirira kuchena sirivha. Menduru dzebhuronzi dzinowanzogadzirwa nendarira (copper-zinc alloy) kana copper tsvuku, ine maumbirwo akasiyana-siyana anowanikwa kuburikidza nekukwenenzverwa uye oxidation. Masimbi aya ndiwo akasarudzika sarudzo yekugadzira menduru nekuda kwekusimba, kupenya, uye kukosha kwechiratidzo.
Kukwidzwa kweAlloys neEco-Zvishandiso Zvinoshamwaridzana
Kuti uderedze mutengo kana kusangana nezvinodiwa zvekugadzira, menduru zhinji dzave kugadzirwa nemaalloys. Semuenzaniso, menduru dzebhuronzi dzinogona kusanganiswa nezvinhu zvakaita serata uye zingi kuti zviwedzere kuoma. Dzimwe menduru dzechirangaridzo dzinoshandisa aruminiyamu alloys, ayo akareruka uye anoramba kune oxidation. Mumakore achangopfuura, kuziva kwezvakatipoteredza kwakafambisa hunyanzvi mune menduru zvinhu. Zvimwe zviitiko zvakasarudza kushandisa simbi dzakadzokororwa (senge sirivheri yakadzokororwa nemhangura yakadzokororwa) mumamenduru adzo, zvichifambirana nemaitiro ebudiriro uye kusimudzira hunhu hwegirinhi. Pamusoro pezvo, titanium, nekuda kwekureruka kwayo, kusimba kwepamusoro, uye kugarisana kwehupenyu, iri kuramba ichishandiswa mu-menduru dzekupedzisira, ichidzipa pfungwa yehunyanzvi uye nekunaka kweramangwana.
Kuongorora Zvisiri-Metallic uye Composite Materials
Kupfuura simbi dzechinyakare, miganhu yezvinhu zvemenduru iri kuramba ichiwedzera. Mimwe mibairo yakakosha inoshandisa zvinhu zvakaita seenamel, kristaro, huni, kana kabhoni fiber, inosimudzira dhizaini yavo yakasarudzika kuburikidza neakaiswa simbi plaques kana maitiro akasanganiswa. Semuenzaniso, menduru dzemapuranga dzakabatanidzwa nemafuremu esimbi dzinochengetedza masikirwo echisikigo ichiwedzera kubata kwekudziya kwevanhu. Enamel matekiniki anogona kugadzira akapfuma mavara uye mapatani ruzivo. Composite zvinhu zvinonyanya kukodzera kune zvakagadzirirwa zvinodiwa. Semuyenzaniso, kubatanidza simbi neresin kana acrylic zvinowana chiyero pakati pehuremu uye hunyanzvi mhedzisiro.
Kusarudzwa kwezvinhu zvemenduru kunoda kutariswa kwakadzama kwekukosha kwekufananidzira, kudzora mutengo, kusimba, uye dhizaini zvinodiwa. Kubva pagoridhe rekare, sirivheri, nebhuronzi kuenda kuzvinhu zvitsva, zvine hushamwari kwezvakatipoteredza, kushanduka kwezvinhu hakungotakura rukudzo chete asiwo kunoratidza kusanganiswa kwebudiriro yetekinoroji netsika nemagariro. Kunzwisisa izvi zvinhu zvemukati zvinogona kubatsira zvirinani kugadzira uye kusarudza menduru zvigadzirwa zvinosangana nezvinodiwa zveakasiyana mamiriro.
