Mu rwego rw'ibikoresho byo gusiga irangi, ishingiro rya granite, nk'igice cy'ingenzi cy'ingenzi, rigira uruhare runini mu gutuza, gukora neza no mu buzima bw'ibikoresho. Ubushinwa n'Uburayi na Amerika buri kimwe gifite imiterere yacyo mu ikoreshwa n'iterambere ry'ikoranabuhanga ry'ishingiro rya granite. Iyi nkuru izakora isesengura rigereranya mu buryo butandukanye kugira ngo itange ibisobanuro birambuye ku bakora mu nganda n'abazikurikira.
I. Kugereranya inzira za tekiniki: Buri imwe ifite ibyiza byayo
Uburayi na Amerika byatangiye mbere mu bijyanye no gutunganya ishingiro rya granite. Gukusanya igihe kirekire byabahaye amahirwe mu buhanga bwo gutunganya neza cyane. Urugero, ibigo by'Abadage byakoresheje ikoranabuhanga ryo gusya rito cyane, rishobora kugenzura ubukana bw'ubuso bwa granite muri Ra≤0.1μm no kugera ku bugari bwa ±0.5μm/m, bigatuma ikoreshwa mu bikoresho byo gusiga bifite ubushobozi bwo gupima neza cyane. Bamwe mu bakora ibikoresho muri Leta Zunze Ubumwe za Amerika ni abahanga mu ikoranabuhanga ryo gutunganya imashini, bahuza granite n'ibikoresho byihariye by'icyuma kugira ngo bongere imiterere y'ishingiro.
Mu myaka ya vuba aha, Ubushinwa bwagiye butera imbere cyane mu ikoranabuhanga, cyane cyane mu mikorere minini no gutunganya ibintu byihariye. Ibigo byo mu gihugu bishobora kurangiza neza gutunganya ishingiro rya granite rifite imiterere igoye binyuze mu gukoresha ikigo cyabyo cyakozwe ku giti cyacyo gifite amashami atanu. Byongeye kandi, binyuze muri sisitemu yo kugenzura ubuziranenge bw'amakuru menshi, igipimo cy'ibicuruzwa gishobora kwiyongera kikagera ku kigero kirenga 98%. Binyuze mu guhuza ibikoresho mpuzamahanga bigezweho n'udushya twigenga, ZHHIMG® yageze ku bushobozi bw'umwaka bwo gukora ishingiro rya granite zisaga 10.000 mu gihe igenzura ko zikora neza cyane, zigahura n'ibikenewe ku masoko yo mu gihugu no mu mahanga.
Icya kabiri, ikiguzi n'imikorere y'ikiguzi: Ibicuruzwa byo mu gihugu bifite inyungu zikomeye
Bitewe n'ishoramari rinini mu bushakashatsi n'iterambere ry'ikoranabuhanga ndetse n'ikiguzi cy'abakozi kiri hejuru, ibiciro by'ibice bya granite muri rusange biri hejuru. Fata urugero rw'ibice bya granite bifite imiterere imwe (1500mm × 1000mm × 200mm). Igiciro cy'ibicuruzwa biva mu Burayi na Amerika ubusanzwe kiri hagati y'amadolari ya Amerika 30.000 na 50.000, mu gihe igiciro cy'ibicuruzwa bisa mu Bushinwa ari hagati ya RMB 20.000 na 40.000 gusa, ibyo bikaba bifite inyungu ikomeye ku giciro.
Ku bijyanye n'umusaruro w'ibiciro, ibicuruzwa byo mu gihugu cyacu byakoze neza cyane. Ibigo by'imbere mu gihugu byagabanyije cyane ibiciro binyuze mu kunoza imicungire y'uruhererekane rw'ibicuruzwa, bigeraho umusaruro uhuriweho kuva mu gucukura ibikoresho fatizo bya granite kugeza mu gutunganya ibicuruzwa byarangiye. Muri icyo gihe, mu rwego rwo kwemeza imikorere y'ibanze (nk'ubucucike bwa 3100kg/m³ n'imbaraga zo gukanda za ≥200MPa), ubushobozi bw'ibicuruzwa burushaho kwiyongera binyuze mu guhanga udushya mu ikoranabuhanga, bigatuma birushaho kuba byiza ku bigo bito n'ibiciriritse bifite agaciro gake ndetse n'amasoko manini.
III. Itandukaniro mu ikoreshwa ry'isoko: Ishingiye ku busabe bw'abaguzi ni yo igena imiterere
Ishingiro rya granite ryo mu Burayi no muri Amerika rikoreshwa cyane cyane mu bikoresho byihariye, nk'ibikoresho byo gusiga amarangi ku kabati k'ibikoresho byo kwerekana ibintu by'agaciro n'imirongo yo gusiga amarangi ku buryo bunoze mu kirere, nibindi. Ibi bikoresho bifite ibisabwa byinshi kugira ngo ibidukikije bihuze neza kandi bihamye cyane. Urugero, mu bikoresho bimwe na bimwe byo gusiga amarangi ku isaha yo mu Busuwisi, ishingiro rya granite ryo mu Burayi no muri Amerika rikoreshwa rigomba gutsinda ibizamini bikomeye byo kurwanya amashanyarazi n'ibizamini byo gusiganwa ku maguru no ku bushyuhe buri hejuru.
Ishingiro rya granite mu gihugu cyacu rikoreshwa cyane mu bikoresho byo gusiga irangi bikoreshwa n'abantu benshi bitewe n'uko bihendutse, nko gusiga irangi ku mashini zigendanwa n'ibikoresho byo gusiga irangi ku buso bw'inzu. Hagati aho, mu nzego zikiri kuzamuka nko ku isoko ry'ibikoresho byo gusiga irangi ku masanduku mashya y'imodoka zikoresha ingufu, ibicuruzwa byo mu gihugu na byo byinjiriye vuba. Bitewe n'uburyo bwihuse bwo gusubiza no gutanga serivisi zihariye, bihaza ibyifuzo bitandukanye by'abakiriya.
Iv. Inzira z'iterambere ry'ejo hazaza
Uburayi na Leta Zunze Ubumwe za Amerika bizakomeza kwibanda ku bushakashatsi no guteza imbere ikoranabuhanga rigezweho, gusuzuma ikoreshwa ry’ibikoresho bishya bya granite, no kunoza imikorere y’ishingiro. Hashingiwe ku guhuza ibyiza bihari, Ubushinwa bwongereye ishoramari mu bushakashatsi no mu iterambere, buteza imbere inganda zigana ku rwego rwo hejuru, bushimangira guhuza n’amahame mpuzamahanga, kandi bunoza ubushobozi bwabwo bwo guhangana ku isoko ryo ku rwego rwo hejuru ku isi. Mu rwego rwo guhanahana amakuru mu bya tekiniki no guhangana ku isoko, impande zombi ziteganijwe ko zizafatanya guteza imbere iterambere rishya ry’ibikoresho bya granite mu rwego rwo gusiga irangi ry’ibikoresho byo kwerekana.
Byaba ari uguhitamo ibikoresho by'ibanze bya granite biva mu Bushinwa cyangwa mu Burayi no muri Amerika, ibigo bigomba gusuzuma neza hashingiwe ku byo bakeneye ku bikoresho byabo, ingengo y'imari n'uburyo bikoreshwa. Kugira ngo umenye byinshi ku bikoresho by'ibanze bya granite n'ibisubizo bya tekiniki, nyamuneka komeza urebe uko inganda zimeze cyangwa uhamagare abatanga serivisi babigize umwuga kugira ngo bakugezeho serivisi zihariye.
