Igiciro cyumvikana 16 santimetero Umuyoboro udafite ibyuma SCH40

Ibisobanuro bigufi:

Umuyoboro wicyuma udafite ibikoresho byifumbire mvaruganda nicyuma cyiza cya karubone

naibyuma bivanga ibyuma bidafite icyumabikwiranyeibikoresho bya shimi naumuyoboro.

Ubu bwoko bwicyuma muri GB6479-2013.

Ibicuruzwa

Ubu dufite imashini zihanitse. Ibisubizo byacu byoherezwa muri Amerika, Ubwongereza nibindi, twishimira izina hagati yabaguzi ku giciro cyiza 16 santimetero y'icyuma kitagira ibyuma SCH40, Ubu twashyizeho imikoranire mito kandi miremire mito mito hamwe n’abaguzi baturuka muri Amerika ya Ruguru, Uburayi bw’iburengerazuba. , Afurika, Amerika y'Epfo, ibihugu n'uturere birenga 60.
Ubu dufite imashini zihanitse. Ibisubizo byacu byoherezwa muri Amerika, Ubwongereza nibindi, twishimira izina hagati yabaguzi, Turibanda mugutanga serivise kubakiriya bacu nkikintu cyingenzi mugushimangira umubano wigihe kirekire. Guhora tubona ibisubizo byo murwego rwohejuru duhujwe na serivise nziza yo kugurisha mbere na nyuma yo kugurisha bituma irushanwa rikomeye ku isoko rigenda ryiyongera ku isi.

Incamake

Gusaba

Umuyoboro wicyuma udafite ibikoresho byifumbire mvaruganda yumuvuduko mwinshi nicyuma cyiza cya karubone cyubatswe nicyuma kivanze nicyuma kitagira ibyuma bikwiranye nibikoresho bya chimique.
