Isahani yicyuma nicyuma kiringaniye giterwa nicyuma gishongeshejwe hanyuma ugakanda nyuma yo gukonja.
Urupapuro rwicyuma ruringaniye, urukiramende kandi rushobora kuzunguruka cyangwa gukata kumurongo mugari.
Ibyapa by'ibyuma bigabanijwe ukurikije ubunini, isahani yoroheje iri munsi ya mm 4 (inanutse ni mm 0,2), icyuma giciriritse hagati ya mm 4-60, naho icyuma kibyibushye cyane ni 60-115 mm.
Amabati yicyuma agabanijwemo isahani ishyushye hamwe nisahani ikonje ukurikije kuzunguruka.
1. Isahani ishyushye
Uburyo bushyushye bwo gutunganya burimo gushyushya, guhimba, gukuramo n'ubundi buryo.
2. Isahani ikonje
Uburyo bwo gutunganya ubukonje burimo gukonjesha gukonje, gushushanya gukonje no gushushanya imbeho, kunama gukonje, gukuramo ubukonje nubundi buryo.
Uburyo bukonje bukonje nugukomeza gutunganya ibyuma bishyushye bishyushye munsi yubushyuhe bwa rerystallisation kugirango bikore ibyuma bikonje.Gukoresha uburyo bukonje bwo gutunganya birashobora kunoza imiterere yicyuma, kandi ukabona ibicuruzwa bifite uburinganire buringaniye kandi bworoshye.
Ikibazo: Waba ukora uruganda?
Igisubizo: Yego, turi uruganda rukora ibyuma bya Carbone, Dufite uruganda rwacu, ruherereye i Shandong, mubushinwa.Dufite imbaraga zambere mugukora no kohereza hanze ibyuma bya karubone, impapuro zikonje zikonje, nibindi. Turasezeranya ko aricyo ushaka.
Ikibazo: Turashobora gusura uruganda rwawe?
Igisubizo: Murakaza neza nimara kugira gahunda yawe tuzagutwara.
Ikibazo: Ufite igenzura ryiza?
Igisubizo: Yego, dushobora kwakira BV, SGS ubugenzuzi bwa gatatu.
Ikibazo: Urashobora gutegura ibyoherejwe?
Igisubizo: Nukuri, dufite ibicuruzwa bitwara ibicuruzwa bihoraho bishobora kubona igiciro cyiza mubigo byinshi byubwato kandi bigatanga serivisi zumwuga.
Ikibazo: Igihe cyawe cyo gutanga kingana iki?
Igisubizo: Mubisanzwe ni iminsi 7-14 niba ibicuruzwa biri mububiko.cyangwa ni iminsi 25-35 niba ibicuruzwa bitarimo ububiko, bikurikije ubwinshi.
Ikibazo: Nigute dushobora kubona ibyifuzo?
Igisubizo: Nyamuneka tanga ibisobanuro byibicuruzwa, nkibikoresho, ingano, imiterere, nibindi. Turashobora rero gutanga ibyiza.
Ikibazo: Turashobora kubona ingero zimwe? Amafaranga yose?
Igisubizo: Yego, urashobora kubona ingero ziboneka mububiko bwacu.Ubusa kuburugero nyarwo, ariko abakiriya bakeneye kwishyura ikiguzi cy'imizigo.
Ikibazo: Nigute ushobora gukora ubucuruzi bwacu igihe kirekire kandi umubano mwiza?
Igisubizo: 1.Tugumana ubuziranenge bwiza nigiciro cyo gupiganwa kugirango tumenye inyungu zabakiriya bacu.
2.Twubaha buri mukiriya nkinshuti yacu kandi dukorana umurava ubucuruzi no kugirana ubucuti nabo, aho baturuka hose.
