Eyona Ntsika yentsimbi igqwesileyo yobunjineli obunezibophelelo zentsimbi exineneyo
Umtya wentsimbi oxinezelekileyo yintambo yentsimbi exinezelekileyo eyenziwe ngeentambo zentsimbi ezi-2, 3, 7 okanye 19 ezinamandla aphezulu, kwaye iye yafumana unyango lokunciphisa uxinzelelo (unyango lokuzinza), olufanelekileyo kwikhonkrithi exinezelekileyo okanye iinjongo ezifanayo.
Iimpawu eziphambili zemicu yentsimbi exineneyo ngamandla aphezulu, ukusebenza kakuhle kokuphumla, kwaye ithe tye xa ivuliwe. Umgangatho oqhelekileyo wamandla okutsalwa yi-1860 MPa, kwaye kukho amanqanaba omandla afana ne-1720, 1770, 1960, 2000, kunye ne-2100 MPa. Amandla okuvelisa le ntsimbi nawo aphezulu kakhulu.
Intonga yentsimbi yentsimbi enekhabhoni ephezulu itsalwa ngokubandayo kwintambo yentsimbi emva kokulungiswa komphezulu, kwaye emva koko inani elithile leentambo zentsimbi zijijwa zibe yimicu ngokwesakhiwo sentambo yentsimbi, kwaye emva koko zenziwe ngenkqubo yokuzinzisa uxinzelelo. Ukuze kwandiswe ukuqina, ucingo lwentsimbi lunokuba neplating yesinyithi okanye engeyiyo yesinyithi okanye i-coating, efana ne-galvanizing, i-epoxy coating, njl. Ukuze kwandiswe amandla okubopha ngekhonkrithi, umphezulu unokuba nee-nicks njalo njalo. Intambo yentsimbi eboshiweyo efakwe i-mold idlula kwinkqubo yokucinezelwa kwe-mold emva kokunamathela, isakhiwo sixinene ngakumbi kwaye umaleko womphezulu ufanelekile ngakumbi ukubambelela. Ukwenza imicu yentsimbi engabotshelelwanga (imicu yentsimbi engabotshelelwanga) sebenzisa imicu yentsimbi eqhelekileyo efakwe i-pre-stressed, egqunywe nge-anti-corrosion grease okanye i-paraffin wax, ize isongwe nge-high-density polyethylene (HDPE).
