Amakuru y'Isoko

Nk’uko byatangajwe n’itangazamakuru rya Repubulika ya Irani ku ya 4, ishami rishinzwe imibanire n’abaturage ry’umutwe w’ingabo zirinda impinduramatwara ya kisilamu (IRGC) ryavuze ko nta bwato bw’abacuruzi cyangwa amato ya peteroli bwanyuze mu muyoboro wa Hormuz mu masaha make ashize, rihakana ibivugwa na Amerika ko amato yari asanzwe anyura muri uwo muyoboro nk’“ibidafite ishingiro kandi ari ikinyoma rwose”. Raporo yongeyeho ko ibikorwa byose byo mu mazi binyuranyije n’amahame yashyizweho n’ingabo zirwanira mu mazi za IRGC bizahura n’“akaga gakomeye”, kandi amato atubahiriza amategeko “azafatwa ku ngufu”.

Ku itariki ya 4 Gicurasi ku isaha yo mu gihugu, umunyamakuru wo muri China Media Group yamenyeshejwe n’ikigo gishinzwe ubucuruzi bw’amazi mu Bwongereza (UKMTO) ko ikigo gishinzwe ubutasi bw’amazi cyasohoye itangazo nimero 004-26, rivuga ko bitewe n’ibikorwa bya gisirikare bikomeje gukorwa mu karere, urwego rw’umutekano w’amazi mu nyanja ya Hormuz rukomeje kuba "rwo hejuru cyane", hamwe n’ingaruka z’ibikorwa byo kugenda mu mazi ziyongera. Iri tangazo ryagaragaje ubwiyongere bukabije bw’ubwiyongere bw’amazi mu mazi ajyanye n’ibyo bikorwa ndetse n’ubwiyongere bw’urwego rw’uburinzi, bivuze ko amato atwara abantu ashobora kwakira itumanaho rya VHF kenshi, mu gihe ubucucike mu bice birebwa n’indege bwarushijeho kwiyongera bitewe n’umuvuduko w’imodoka. Ryashimangiye by’umwihariko ko bitewe n’ibirombe bitazwi neza mu mazi amwe na amwe, ingendo mu bice biri hafi ya gahunda yo gutandukanya imodoka (TSS) zifite "ingaruka zikomeye cyane". Amasosiyete y’ubwikorezi aragirwa inama yo gusuzuma neza ingaruka, gutegura inzira mbere y’igihe, no kugenzura umutekano mbere y’uko amato ajyanwa mu bwato. (Isoko: CCTV News)

Isesengura ryimbitse

Mu minsi mikuru ya Gicurasi, amakimbirane hagati ya Amerika na Irani yahungabanyije isoko ry'ingufu, bituma PVC ihura n'ibintu bitandukanye kandi bihindagurika. Ku ruhande rw'ibicuruzwa, ibiciro by'ibikomoka kuri ethylene byakomeje kuba hejuru bitewe n'ingufu nke z'imbere mu gihugu no mu mahanga, aho abakora mu mahanga bagabanya umusaruro kugira ngo bashyigikire ibiciro naho ibyoherezwa mu mahanga mu Bushinwa bigakomeza gukomera. Kubungabunga no kugabanya umusaruro mu mpeshyi kw'ibigo byahombye byarushijeho kugabanya igipimo cy'imikorere y'inganda, bituma ibikoresho bikurwa mu nganda. Ku ruhande rw'ibikenewe, ishoramari mu mutungo utimukanwa ryakomeje kugenda buhoro, aho abaguzi bo mu nganda basubiranye gusa ibikoresho by'ingenzi bihendutse n'ibyo batumiza mu nganda bike. Ibigo byinshi byo mu nganda byafashe iminsi 3-4 y'ibiruhuko ahagana kuri Gicurasi, bigatuma ibicuruzwa bidatanga umusaruro n'ibikenewe bidatanga umusaruro. Muri rusange, kugabanuka kw'ibicuruzwa n'ibiciro byashingiweho n'ibiciro byashingiweho, ariko ubushobozi buke bwo kubisaba bwagabanyije ubushobozi bwo kuzamuka. Mu gihe gito, PVC ishobora kuzamuka buhoro buhoro, nubwo ibiteganijwe ko bizahinduka ku rugero rwo hasi. Mu gihe kiri imbere, hagomba kwibandwa ku gushyira mu bikorwa igabanuka ry'umusaruro n'ingaruka z'umuvuduko wo kuzamuka kw'ibicuruzwa ku rwego rw'inganda.

Incamake

Igitekerezo: Kubera ko ibicuruzwa bigabanuka buhoro buhoro kandi icyifuzo kigakomeza kuba gito, PVC ejo hazaza biteganijwe ko izakomeza kuba mu buryo budakomeye.

Ishingiro ry'Imitekerereze:

Ibura ry’ibiryo bya ethylene ntirishobora kugabanuka mu gihe gito. Abakora mu mahanga barimo kugabanya umusaruro kugira ngo bagere ku biciro, mu gihe ibyoherezwa mu mahanga mu Bushinwa bigumana inyungu zo guhangana. Hamwe n’igabanuka ry’ibicuruzwa byitezwe mu gihe cyo kubungabunga impeshyi, ibi bintu bigize inkunga yo hasi ku isoko.

Iterambere ry’ishoramari mu iterambere ry’ubutaka riracyari hasi, nta ntambwe igaragara yatewe n’inganda zikora ibicuruzwa biri inyuma, zisubiramo gusa ibicuruzwa ku giciro gito kandi zigaragaza ko zitabira ibikoresho bihendutse. Nubwo ibicuruzwa by’inganda birimo kugabanuka, umuvuduko uri hasi, kandi urwego rwo hejuru rw’ibikoresho hamwe n’ubukene bw’ibicuruzwa bikomeje kugabanya izamuka ry’ibiciro.
