INqanawe Zokugcina Nomalunga Nemibuzo Ebalulekileyo: Ngubani Metali Ukhuseleko?

Uma ungena yonwaba, ongqiya noma ongqaleka elibomvu ngemvume 1999-2000, kunye nomntu owenza umoya okanye amalungiselelo? Izintlanzi zikunjalo zingazibuyisela ngokuthi iimaterial ezilandelayo ezithile. Lolu hlobo lwezintlanzi ziyaziwa ngokuba zikhona ngokulandelana. Demai ukuya ukuze ahlalelele ukumema abantu abangene ukuthi abasebenzi.

Iimpahla Yezintlanzi Zokhapho

Izintsholo zomentali zinamandla ezininzi ngaphezulu kwezintsholo zakarubha noma zakhiphise. Ngoxolo lokuvumelwa ngalokho, izintsholo zomentali zingakho ngenkathi amanqaku kunye nezinye iindlela zabo. Zihlobene ngebuyile nobukhonziswa bokugcineni kunye nokugcinwa kwiindawo ezincinci ezinkathayo kunye nezindawo ezincinci ezinkqabekayo. Lokhu kufuneka ukuba zikhuse lapho zikhanyiswe ngokupheleleyo kwiindawo ezidingekayo, njengemilayithi kunye nezindawo zokusebenza ezincono zabo zikuxhaswe imigomo. Izintsholo zomentali zibuyelela ukusuka kwezinto eziphumeleyo zazo kumazibuko, ezifakeleyo, kuncane.

Izintsholo zomentali zonke izizukulwane kakhulu. Izintsholo zomentali zingasetyenziswa ngokukhala kakhulu kumaqhawe eliphantsi lokuhlola kancane kunye namagqabi akarubha kunye namaphlase, okungangeyiyo ukuthi aziphumeleyi. Oku kwenziwa ukuba babekho abahlobo abaningi lokusebenzisa kwiindlela ezidingekayo ezincedisi ukusetyenziswa kunye nokusetyenziswa.

Ukuthi Demai Iyaphumelela

Demai yintlango engasebenzisa amantšho amahle ometalini wokuva kuzo lwazi oluhlinzekelayo. Imantšho yethu yomentali kunye  Amabhokisi kwezolo lwezintanki zivumelelwa ngezinto ezincedwe ngokuthi zilandelwe amaxesha, njengemhlophe wehlathi, inikelu nebronze ukuvumela ukuba zisisekelwe kakhulu – umoya omunye kuqala kunye nomsebenzi ongaphambi kokulula. Ngokugunya, izixhasi zethile zethelwe ngaphandle kwezinye izindlela ezidinga lokuhlola ngenxa yezifityelelo ezithile, ukuba zikhankanyiswe kanye nokusetyenziswa ngokuqinisekileyo kwiingxenye ezininzi.

Iingxabano Zesixhasi SeRubber NgesiPlastic

Umviko — Rubber vs Metal → UmsowuWangaphezu kokuba zihlobene nesixhasi sesiPlastic  Amanxovu amancampe  futhi zincedisiwe ngokubanzi ukwenza nokuba zingasinyeka kodwa, zinamandla eminingi ngaphezulu kwisebenti esihlahliweyo. Isigodlo esincinci sisho ukuba amaxesha amahlati akanye namaxesha amaphlashtik le awukwazi ukuba zisisekelwe ngakuphi na. Ngendaweni, kodwa, zizibonelela okanye zizidale ngexesha elishumi lokusebenza. Ukufa kwesintsiweyo noma imfula yesiqephu phakathi komkhanda kuhlanganisa isiphumo esikhulu, futhi ukuba umoya okanye umfula usebenzise ngaphandle komphendulo, usetyenziswa lokho kufanele aluhluleke ukuze alitshabalalise major hazardous issues.

Ngokushesha, imibuzo engakapheliyo okanye amandla adabuko akukho ngenxa lezityalo ezimbili. Ngoko ke, zingene ukubhakanyiswa ngezinye izinto lokuhlola kumthetho wabo ngokusebenza ukuba zikhawulekile kwiqhutywa eliphakamisekileyo. Izityalo zeRubber nePlastic zizibhethekile kwiqhutywa elihlobene nomtheleli omkhulu, uzoba zikwazi ukususa amafile apha kwiqhutywa elihlobene nomtheleli omkhulu, ukuze zisetyenziselwe ngokupheleleyo kwiqhutywa elidinga umsindo womtheleli omkhulu. Izityalo zeRubber nePlastic zizibhethekile kwiqhutywa elihlobene nomtheleli omkhulu, uzoba zikwazi ukususa amafile apha kwiqhutywa elihlobene nomtheleli omkhulu, ukuze zisetyenziselwe ngokupheleleyo kwiqhutywa elidinga umsindo womtheleli omkhulu.

Uma useto usiza ukuba kudingekileyo ukusetyenziswa kwiqhutywa elihlobene nomtheleli omkhulu, isetyenziso esisodwa sikaRubber asikwazi ukusuka ngaso ukusetyenziswa, ndawonye iimetalu yezityalo zizobuyaleka ukuba ziyahlola imithetho yakho.

Iimetalu yezityalo zizosetshenziswa kunye nokusetshenziswa kwiqhutywa elihlobene nomtheleli omkhulu. Iimetalu yezityalo ye-Demai zidinga ukusetyenziswa kwiqiniso lemfuthe -270°C ku-800°C kunye nokusetshenziswa namandla uphantsi kwe-1500 bar. Zidinga ukusetyenziswa kwiqiniso lokugcina ukuthi lula kunye nokuthi luhlobene nomtheleli omkhulu, njengesiyafo somsebenzi wesayensi, okanye indlunkulu yesiYiphi neGasi.

Inani lokugcinwa lehose zemetali zisebenzisa ukuthi uhlalelo amasili (isithuthi, umlayiso wamathuluzi) endaweni yokusebenzela iimfanele. Ngenxa yoko: Zihlose lweehose ngokushesha Amanxovu we-EPDM  kufuneka zibekelene neentsha kunye nokuhlola ukuvamile kokuthutha kwaye nokuhlola izindlela ezidingekayo. Ngakwesobukhulu, iihose zemetali zisebenzela khetho lomsebenzi olungaphandle lwesintsho ngesintsho lweengcelo ngezingxenyeni eziphakamisayo.

Iingxelo Ezifana Naye Emetal Hoses Ikhetho Lwesikhashu Kwaye Oil and Gas

Iihose zemetali ziyingxenye yezilungileyo ukusetyenziswa kulesi sicelo sokusebenzela i-aerospace ngokubanzi kunye nokuhlola. Ayinakuhlola amagwave amandla emanqaku, futhi ungene ukusetshenziswa kumncedisi kunye nokuhlanganiswa nesixhumanisi. Ngakwesobukhulu, iihose zemetali azitshabalalise amagase egciniwe okudingeka ukuphuma ngaphandle komthwalo, ndiyinikeza ukusetshenziswa kumncedisi we-space kunye neziyethi zonke ezikhethweneyo apho ukuphazamiswa kufuneka kube uphawuli.

Izintlanzi zomentali zisebenzela ngemibuzo engeyiyo kwiindlela ezininzi ngasemanzini somazwi wobuthongo nobhulandle. Le nto ifaka ukukhupha iimfuyo somazwi neengxenye yezilungileyo phakathi kweendlela ezifundekwabo nokuhlola. Izintlanzi zomentali, ngokubheka, ziziphindaphindi amaxwebhu kunye nezinhlangano, zingatshabalalisa amafu specifically imfuyo esincinci kunye nemfuyo wesithathu wepetroleum. Iziphetho zomentali zihlaba ngokukholelwa kunye nokugcina izinye zama-awuli, okunqume kumazwi wobuthongo nobhulandle inqwaba ngasemva kwamandla.
