Birazwi neza ko ireme ryakare ya galvanised hamwe nuyoboro urukiramendenuburyo bwo kwishyiriraho bugira ingaruka itaziguye kumiterere yibyuma.
Kugeza ubu, ibikoresho byunganira isoko ni ibyuma bya karubone. Ibikoresho fatizo byibyuma bya karubone muri rusange Q235 na Q345, bivurwa na galvanizing ishyushye. Inkunga ikozwe mumashanyarazi yicyuma binyuze mukugonda ubukonje, gusudira, gushyushya ubushyuhe nibindi bikorwa. Mubisanzwe, umubyimba ugomba kuba urenze 2mm, na cyane cyane kubice bimwe na bimwe byo ku nkombe, kuzamuka cyane hamwe n’ahantu h’umuyaga n’uturere, birasabwa ko umubyimba utagomba kuba munsi ya 2,5mm, bitabaye ibyo hakabaho ibyago byo gutaburura ibyuma aho uhurira.
Mu nyubako nini zubaka, kuriibyuma bya karubone byashizwemo kare hamwe nu miyoboro y'urukiramende, ubunini bungana iki bwa zinc bugomba kugerwaho kugirango byuzuze ibisabwa mubuzima bwa serivisi yangirika?
Nkuko twese tubizi, ubunini bwa hot-dip galvanizing ni ireme ryingenzi na tekinike ya tekinike yaUmuyoboro wa kare, bifitanye isano numutekano nigihe kirekire cyimiterere. Nubwo hariho amahame yigihugu nu mwuga, ubunini bwa zinc butujuje uburinganire bwinkunga buracyari ikibazo cya tekinike yinkunga.
Igikoresho gishyushye cyane ni gahunda ihamye kandi yizewe yo gutunganya ibyuma byo kurwanya ibidukikije. Hariho ibintu byinshi bigira ingaruka kumashanyarazi ashyushye, nkibigize ibyuma byubatswe, ibyuma byo hanze (nkuburakari), imihangayiko yimbere ya substrate, nubunini bwinshi. Muri iki gihe, ubunini bwa substrate bugira ingaruka zikomeye kumubyimba wa hot-dip galvanizing. Mubisanzwe, umubyimba mwinshi ni nini, nubunini bwubushyuhe-bushyushye. Inkunga ifite umubyimba wa 2.0mm ifatwa nkurugero rwo kwerekana ingano yubunini bwa zinc isabwa kugirango ubuzima bwa serivisi bwangirika bushobore kubaho.
Dufate ko ubunini bwibikoresho fatizo byingirakamaro ari 2mm, ukurikije ibipimo bisanzwe bya GBT13192-2002.
Nubuhe burebure bwikigero cya galvanised umuyoboro wa kare usabwa kugirango wuzuze ubuzima bwa serivisi?
Umuyoboro wa kare
Ukurikije ibisabwa mubipimo byigihugu, ubunini bwibikoresho fatizo 2mm ntibigomba kuba munsi ya 45 μ m. Umubyimba umwe ntugomba kuba munsi ya 55 μ m。 Ukurikije ibyavuye mu kizamini cy’ikirere cyakozwe n’ishyirahamwe ry’Abayapani Hot Dip Galvanizing Association kuva 1964 kugeza 1974.Ni ubuhe burebure bwikigero cya galvanised ya pine ya kare isabwa kugira ngo ubuzima bwa serivisi bushoboke? ?
Niba ubaze ukurikije ibipimo byigihugu, ibirimo zinc ni 55x7.2 = 396g / m2,
Ubuzima bwa serivisi buboneka mubidukikije bine bitandukanye ni:
Agace gakomeye k'inganda: imyaka 8.91, hamwe na ruswa ya buri mwaka ya 40.1;
Agace k'inyanja: imyaka 32.67, hamwe na ruswa ya buri mwaka ya 10.8;
Hanze: imyaka 66.33, hamwe na ruswa yumwaka ya 5.4;
Agace k'imijyi: imyaka 20,79, hamwe na ruswa ya buri mwaka ya 17.5
Niba ubaze ukurikije serivisi ya Photovoltaque ubuzima bwimyaka 25
Noneho urukurikirane rwa zone enye byibuze:
1002.5270135437.5, ni ukuvuga 139 μ m , 37.5 μ m , 18,75 μ m , 60,76 μ m。
Kubwibyo, kugirango isaranganya ryimijyi, uburebure bwa zinc bugomba kuba byibuze 65 μ M birumvikana kandi birakenewe, ariko kubice byinganda biremereye cyane cyane abafite aside na alkali byangirika, birasabwa ko ubunini bwumuyoboro wa kare wa galvanis na zinc coating igomba kongerwaho neza.
