Ubumenyi buke ku bijyanye no gupima hagati y'ibipimo:
Kuva mu 1995, Ishyirahamwe ry’Ibikoresho byo Gupima Ibikoresho by’Ubushinwa ryateguye ibirori 20 byo gupima ibipimo muri Beijing, Chengdu, Shanghai, Hangzhou, Qingdao, Changsha, Nanjing, Guangdong Dongguan na Wuhan. Inganda nyinshi zizwi cyane zitabiriye ibi birori nk’abamurikagurisha. Abanyamwuga benshi n’abaguzi baturutse muri Aziya, Uburayi, Amerika, Oseyaniya na Afurika basuye ibi birori. Ibi birori byagize izina ryiza, binateza imbere ubuhahirane mpuzamahanga n’ubufatanye mu bijyanye no gupima ubukungu n’ikoranabuhanga.
Nyuma y’imyaka myinshi yo guhinga witonze, ubunini n’ingaruka bya InterWeighing byakomeje kwiyongera. Muri iki gihe, InterWeighing yabaye imurikagurisha rikomeye ku isi ry’ibikoresho byo gupima ku rwego mpuzamahanga kandi rifite ubuziranenge bwo hejuru. Igikorwa ngarukamwaka cya InterWeighing cyabaye igikorwa ngarukamwaka gikomeye cyane ku isi mu nganda. InterWeighing yongereye imbaraga mu bukungu n’ikoranabuhanga mu bufatanye hagati y’inganda mpuzamahanga zipima ku rwego rw’isi, kandi yafashije mu iterambere ry’ubucuruzi bw’ibicuruzwa bipima ku rwego rw’isi. Uretse kuba mu ihungabana ry’ubukungu ku isi ryabaye mu 2009, habayeho igabanuka rito, ibicuruzwa bipima ku rwego rw’isi byoherezwa mu mahanga buri mwaka mu Bushinwa byiyongera ku gipimo cyiza cy’iterambere. Mu 2018, nk’uko imibare ya Gasutamo y’Ubushinwa ibigaragaza, ibicuruzwa bipima ku rwego rw’isi byoherezwa mu mahanga byageze kuri miliyari 1.398 z’amadolari y’Amerika; byiyongereyeho 5.2% ugereranyije n’umwaka wa 2017.
Impamvu ibiremereye by'icyuma kidashonga birwanya ingese
Jiajia yongeye kwitabira imurikagurisha ry’inganda rya INTERWEIGHING mu 2020.
Kubera icyorezo, nubwo inshuti nyinshi mpuzamahanga zitashoboye kwitabira igikorwa ngarukamwaka cy’inganda, twakomeje kugeza amakuru y’imurikagurisha kuri buri mukiriya binyuze kuri interineti, harimo ikoranabuhanga rishya, ibicuruzwa bishya, n’iterambere ry’inganda.
Iki gihe cyihariye cyatugejejeho amahirwe menshi yo kuvugana n'abatanga ibicuruzwa bimwe mu nganda. Menya ikoranabuhanga rishya n'iterambere mu nganda. Twaganiriye ku bijyanye n'icyerekezo cy'ibicuruzwa mu gihe kizaza n'iterambere ryabyo hamwe nabo. Mu isoko rishya, ibicuruzwa bizarushaho kunozwa, bizafasha ibigo gukora neza ibicuruzwa no gukora ubushakashatsi ku bicuruzwa bigezweho ku masoko atandukanye. Dushingiye ku bunararibonye bw'abakiriya, tuzatunganya ibicuruzwa neza kandi birambuye. Hamwe mu bijyanye n'imikorere, umutekano n'ubwiza birarushaho kuba byiza.
Ibiremereye by'icyuma kidashonga bifite imiterere yo kudashonga, ibyo bigabanya amakosa y'ibiremereye mu gihe cyo kubikoresha. None se kuki icyuma kidashonga gifite imiterere yo kudashonga cyane? Impuguke mu by'uburemere bw'icyuma kidashonga zizagusobanurira.
Nkuko byavuzwe mu gitabo cy’ubumenyi bw’icyitegererezo cy’amashuri yisumbuye, ibyuma byose bikorana na ogisijeni mu kirere bigatera ogisijeni ku buso bw’ikintu. Ogisijeni ikorerwa ku buso bw’icyuma gisanzwe cya karuboni ihura n’ingaruka za ogisijeni, hanyuma ingese irushaho kwiyongera buhoro buhoro, amaherezo hagakorwa umwobo w’icyuma. Ibi byakorwa bite? Ubusanzwe, uburyo buri wese akoresha ni ugukoresha irangi cyangwa icyuma kidapfa kwangirika mu kurinda amashanyarazi, kugira ngo ogisijeni iri ku buso bw’icyuma itoroshye kwangirika. Kurwanya ingese kw’icyuma kidapfa kwangirika biterwa ahanini no kuba hari ikintu gito, ni ukuvuga chromium, nacyo kikaba ari kimwe mu bigize icyuma.
Iyo chromium igeze kuri 11.7%, ubushobozi bwo kurwanya ingese mu byuma bitagira umugese buriyongera cyane, ibyo bigatuma ibyuma bitagira umugese birushaho gukomera. Ntabwo chromium yiyongera gusa, ahubwo chromium n'icyuma bifatanye n'ubuso bw'icyuma, bishobora kurwanya ingese no gukumira ingese. Ubusanzwe, ibara karemano ry'ubuso bw'icyuma rishobora kugaragara binyuze muri oxide y'icyuma, kandi ubuso bw'icyuma kitagira umugese ni ubuso budasanzwe. Byongeye kandi, nubwo ubuso bwangiritse, icyuma cyashyizwe mu kirere kizaba icyuma kirinda ikirere gifite imiterere ibiri, kizwi kandi nka firime ya kabiri yo gusimbuka, ikomeza kurindwa ku nshuro ya kabiri, bityo ikagera ku ntego yo kurwanya ingese.
Murakaza neza ubwoko bwose bw'ubuzima muri Yantai Jiajia Instrument kugira ngo mugure ibikoresho by'icyuma kitagira umugese, kuko ari iby'umwuga kandi byizewe.
