Injira mu ruganda urwo arirwo rwose rukora ibikoresho by’ubuhanga, muri laboratwari y’ibipimo, cyangwa mu ishami rishinzwe kugenzura ubuziranenge, uzabibona ako kanya—igisate kinini cy’ibuye ryijimye kiri ku ntebe y’akazi cyangwa gishyizwe ku gitereko, ubuso bwacyo bukarabagirana munsi y’amatara. Icyo gice cy’amabuye cya granite ni kimwe mu bikoresho by’ingenzi cyane mu nganda: icyuma cyo hejuru.
None se koko plate y'ubuso bwa granite ni iki? Mu magambo make, ni plane y'icyitegererezo cy'ubuziranenge ikora nk'umurongo w'ibanze w'ubugari bwo gupima, imiterere, n'imikorere yo gushyiraho ibikoresho. Bumwe mu buso bwayo bw'ingenzi bukozwe mu buryo burambuye cyane, bigatuma buba ibanze aho ibipimo hafi ya byose mu nganda bigenzurwa. Akenshi plate z'ubuso ziza zifite aho zishyirwa, bigatuma zikora nk'ibice by'imiterere mu mashini zipima hamwe n'ibindi bikoresho by'ubuziranenge.
Impamvu abakora ibikoresho bahitamo granite kuruta ibindi bikoresho, ni uko hari imiterere itangaje yatumye ibi bikoresho karemano bidasimburwa mu gupima neza mu gihe kirenga ikinyejana.
Kuki Granite? Ibyiza by'ingenzi
Inkuru y'amasahani yo hejuru ya granite itangirana n'ibikoresho ubwabyo. Bitandukanye n'icyuma gikozwe mu cyuma, ibikoresho byo hejuru byakunze gukorwa mu ntangiriro, granite itanga ituze kandi iramba. Dore icyayigize umwihariko:
Guhagarara neza k'ubushyuhe ni cyo kintu cy'ingenzi kurusha ibindi. Ingano y'ubushyuhe ya Granite ipima gusa 4.61 × 10⁻⁶/°C—ifite ubushyuhe buhamye inshuro 10 kurusha icyuma. Mu bidukikije aho ihindagurika ry'ubushyuhe ridashobora kwirindwa, iki gipimo gito cyo kwaguka bivuze ko icyuma gikomeza kuba cyiza aho ibindi bikoresho byaguka bikagabanuka, bigatera amakosa mu gupima.
Imiterere ya mekanike ishimangira uku kudahinduka. Ifite ubucucike buri hagati ya 2970-3070 kg/m³ n'imbaraga zo gukanda za 245-254 N/mm², granite ikora imirimo iremereye idahinduka. Ubukana bw'inkombe bwa HS70 cyangwa irenga butuma ubuso budashobora kwangirika kandi bugakomeza kuba buto ndetse no mu gihe cy'imitwaro myinshi.
Granite kandi irwanya ingese mu buryo busanzwe. Ntizigwa ingese nk'icyuma, yihanganira ubushuhe idasenyuka, kandi ihangana n'ibintu byinshi byangiza ibidukikije. Amazi anyurwa munsi ya 0.13% bivuze ko ibikoresho bidahinduka cyangwa ngo bihinduke bitewe n'impinduka z'ubushuhe—ikibazo gikunze kugaragara ku mbaho ndetse no ku bikoresho bimwe na bimwe byakozwe mu buryo bwa ikoranabuhanga.
Akamaro kamwe gafatika gakunze gutungura abantu: kwangirika kw'isahani y'ubuso bwa granite ntabwo byanze bikunze kuba ikibazo. Ibikoresho nta ngingo zibitera imbere, bityo uduce duto cyangwa ibyangiritse ku nkengero ntibikwirakwira. Iyo agace kamwe kadakoreshwa, ibindi bice by'ubuso bishobora gutanga ubugari ukeneye.
Imiterere y'ibikoresho n'imiterere ya tekiniki
Granite ikoreshwa muriibyuma bipima neza ubusosi ibikoresho bisanzwe byo kuri konti yawe. Bigizwe ahanini na diabase na plagioclase feldspar, hamwe n'ingano nto ya olivine, biotite, na magnetite iboshye mu buryo bwa kristu.
Izi myunyu ngugu zihurira hamwe zigakora ikintu gifite imiterere idasanzwe. Ingano ya quartz itanga ubukana no kudashira. Imiterere ya kristu ifatanye itanga imbaraga nta gucika intege. Icy'ingenzi kurushaho, inzira yo gushingwa buhoro buhoro mu myaka ya za miriyoni bivuze ko ikintu kidacika intege mu buryo busanzwe—nta gucika intege ku buryo bishobora gutera guhindagurika cyangwa guhindagurika uko igihe kigenda.
Uburyo bwo gukora bukoresha iyi miterere karemano. Nyuma yo gukata no gushushanya neza, granite irasya neza kandi igateranywa kugira ngo igere ku buso burambuye. Ibi si igikorwa cyihuse; kugera ku rugero rwa 000 rw'ubuso bunini bishobora gufata ibyumweru byinshi byo gukuraho ibikoresho no kugenzura ubuso.
Gusobanukirwa amanota meza n'uburyo bwo kwihanganira ibintu mu buryo burambuye
Aha niho abaguzi bakunze kwitiranya ibintu, reka mbisobanure neza.
Ubuziranenge bw'aho plaque iherereye bushyirwa mu byiciro, buri rwego rugaragaza uburyo bwo kunyuranamo mu buryo bwemewe. Uburyo bukoreshwa mu bipimo byinshi—bujyanye n'ibipimo ngenderwaho by'Abashinwa JB/T 7975-1999—bupima ubushobozi bwo kwihanganira ibintu hashingiwe ku burebure bw'aho plaque iherereye:
- Icyiciro cya 000: 1 × (1 + d / 1000) μm, aho d ingana n'uburebure bw'umurongo ugororotse muri milimetero, bupimwe kuri 20 ± 2 ° C
- Icyiciro cya 00: 2×(1+d/1000) μm
- Icyiciro cya 0: 4×(1+d/1000) μm
- Icyiciro cya 1: 8×(1+d/1000) μm
Mu buryo bufatika, icyuma gipima ubugari bwa mm 1000 cya Grade 0 cyaba gifite ubushobozi bwo kwihanganira 8μm—hafi kimwe cya cumi cy'ubunini bw'umusatsi w'umuntu. Igice cya Grade 000 gifite ubushobozi bwo kwihanganira 2μm, bikagishyira mu rwego rwo gupima neza cyane.
Guhitamo amanota biterwa rwose n'ikoreshwa ryawe. Amasahani y'icyiciro cya 000 akoreshwa muri laboratwari zo gupima no mu byumba byo gupima aho gukurikirana ibipimo ngenderwaho by'igihugu ari ingenzi. Amasahani y'icyiciro cya 0 ni yo akoreshwa cyane mu nganda, atanga ubuziranenge buhagije ku mirimo myinshi yo kugenzura nta kiguzi n'umutwaro wo kubungabunga w'amasahani yo hejuru. Amasahani y'icyiciro cya 1 akora imirimo yo gushushanya no gushyiraho ibikoresho aho ubuziranenge butari ingenzi cyane.
Ingano zisanzwe n'amahitamo yo guhindura
Amasahani yo hejuru aza mu ngano zitandukanye kugira ngo ahuze n'ibikoresho bitandukanye. Ingano zisanzwe akenshi ziva ku masahani magufi ya 200 × 200mm ku byumba bito by'ibikoresho kugeza ku masahani manini ya 3000 × 5000mm yo gupima imiyoboro y'ibikoresho. Ubunini buratandukanye kuva kuri 60mm ku mirimo yo kugenzura yoroheje kugeza kuri 400mm ku mirimo ikomeye yo mu nganda aho gukomera ari ingenzi cyane.
Uretse ingano z'ibanze, abakora batanga imiterere itandukanye y'ubuso:
Ubuso busanzwe bukozwe mu gupima no gutunganya imiterere. Utwobo two gushyiramo imigozi twemerera gufatanya ibikoresho nk'udukingirizo twa rukuruzi, udukingirizo, cyangwa ibikoresho by'ubuhanga. Imiterere ya T-slot itanga aho gushyiramo ibikoresho byihariye. Guteranya udukingirizo dufite ibirenge bihinduka bifasha gushyiraho neza ku butaka butaringaniye.
Hari uburyo bunini bwo gushyiraho ibikoresho byihariye buhari ku bikoresho byihariye. Niba ibyo ukeneye bitari mu byiciro bisanzwe, abakora ibikoresho benshi bashobora gukora amapine mu bunini butari ubusanzwe, ubunini, cyangwa bafite imiterere yihariye y'umwobo kugira ngo bihuze n'ibikoresho byawe byihariye n'imikorere.
Porogaramu mu nganda zose
Uburyo amasahani yo hejuru ya granite akoreshwa cyane bugaragarira mu gukoreshwa kwayo mu buryo bugezweho.
Mu gupima neza, bikoreshwa nk'icyitegererezo cyo kugenzura ibikoresho, ibipimo, n'ibice byakozwe n'imashini. Ishami rishinzwe kugenzura ubuziranenge ryishingikiriza ku masahani yo hejuru kugira ngo rigenzure imiterere y'ibice kuva ku byuma bishyirwa mu buvuzi kugeza ku bikoresho bigezweho.
Mu gushyiraho ibikoresho, ibyuma bipima uburebure bitanga uburebure buhamye bukenewe mu gushyiraho ibipimo by'uburebure, ibimenyetso by'uburebure, n'ibindi bikoresho bipima. Abahanga mu by'ubukorikori babikoresha mu gushyiraho uburebure bw'uburebure iyo bashyiraho imashini za CNC cyangwa ibikoresho by'intoki.
Mu nganda zikora ibikoresho, ibyuma bipima ibikoresho bikoreshwa mu gupima ibyuma, ibikoresho byo guteranya ibikoresho by’ikoranabuhanga, n’ibindi bikoresho bipima neza aho ubuziranenge bw’ibipimo bugira ingaruka ku buryo butaziguye ku buziranenge bw’ibipimo.
Ikoreshwa mu nganda rikubiyemo gukora ibice by’indege, ibikoresho byo gukora ibikoresho bya semiconductor, gukora ibice by’imodoka bitunganye, n’ubuhanga rusange mu by’ubuhanga. Umurimo uwo ari wo wose aho ubushobozi bwo kwihanganira ibintu bukenewe ukeneye urwego rwizewe, kandi granite itanga urwo rufatiro.
Ibipimo ngenderwaho byo guhitamo: Guhitamo neza
Guhitamo plate nziza y'ubuso bikubiyemo guhuza ibintu byinshi:
Ibisabwa kugira ubunyangamugayo bituma umuntu ahitamo amanota. Huza amanota y'ikirango n'ibyo ukeneye mu gupima. Kwishyura amanota y'ikiciro cya 000 mu gihe ibikorwa byawe bisaba amanota y'ikiciro cya 0 gusa bivuze ko amafaranga menshi akoreshwa mu kugitunganya akoreshwa kandi bikaba ngombwa ko akoreshwa mu buryo bwo kugitunganya.
Ingano y'ibikenewe biterwa n'umutako munini w'akazi kawe n'aho ukorera. Isahani igomba gushyiramo ibikoresho byawe byo gupima neza kandi ikagira umwanya wo kubikoresha neza nta kurenga impande.
Imiterere y'ibidukikije igira ingaruka ku ituze ry'igihe kirekire. Iyo ikigo cyawe kidafite uburyo bwo kugenzura ikirere, ituze ry'ubushyuhe rya granite riba rifite agaciro kanini kurushaho, ariko ushobora kuba ukeneye gusuzuma ihindagurika ry'ubushyuhe mu bipimo.
Ibikoresho by'inyongera ni ingenzi kugira ngo bikoreshwe neza. Tekereza niba ukeneye ibitereko byo kuringaniza, ibipfukisho birinda, imikandara yo gutwaramo amasahani atwarwa, cyangwa ibikoresho byihariye bikoreshwa mu buryo bwihariye.
Ibisabwa mu gutanga icyemezo biratandukanye bitewe n'inganda. Hari porogaramu zisaba icyemezo cyo gupima gikurikiranwa gituruka muri laboratwari zemewe. Menya neza ko umutanga serivisi ashobora gutanga inyandiko zijyanye n'ubuziranenge bw'imikorere y'imashini yawe.
Kubungabunga no Gutunganya: Kurinda Ishoramari ryawe
Isahani y'ubuso bwa granite ni ishoramari rikomeye, kandi kuyibungabunga neza bituma itanga serivisi yizewe mu myaka myinshi ishize.
Gupima buri gihe ni ingenzi kugira ngo ukomeze kugira icyizere mu bipimo byawe. Amasahani yo mu cyiciro cya 00 asanzwe asaba kongera gupima buri mezi atandatu, mu gihe amasahani yo mu cyiciro cya 0 ashobora kumara amezi cumi n'abiri hagati yo gupima. Ibisabwa ku bwiza bwawe n'inshuro zo kuyakoresha bishobora gutuma habaho igihe gito.
Kwita ku buzima bwa buri munsi bikubiyemo kubungabunga ubuso bwo gukoreraho busukuye kandi burinzwe. Koresha ibikoresho byoroshye kandi bisukuye gusa mu guhanagura. Ntukigere ushyira ibikoresho bifite uduce duto cyangwa impande zityaye ku buso. Irinde ko byagera ku bintu bikomoka kuri aside cyangwa alkaline bishobora kwibasira ibuye uko igihe kigenda.
Kubika neza bifasha cyane igihe cyo gukoresha isahani. Bipfuka ahantu hadakoreshejwe kugira ngo hirindwe ivumbi ryiyongera cyangwa kwangirika ku buryo butunguranye. Bika ahantu hameze neza hafi ya 20±2°C, ubushyuhe buri hagati ya 40-60% uko bishoboka kose.
Uburyo bwo kwirinda kwangirika mu gihe cyo kugenda. Nubwo granite ikomeye, ingaruka zikomeye zituruka ku bikoresho byaguye cyangwa uburyo bwo kuyikoresha nabi zishobora gukata impande cyangwa guteza ibibazo. Koresha uburyo bwo guterura n'ibikoresho bikwiye ku masahani aremereye.
Amahame n'Ibisobanuro by'Inganda
Amabwiriza mpuzamahanga menshi agenga ikorwa n'igeragezwa ry'ibice byo hejuru:
DIN 876 y’Abadage itanga ibisobanuro bizwi cyane mu nganda zo mu Burayi. Ikigo cy’Abanyamerika gikurikiza ASME B89.3.7-2013, cyasimbuye imiterere ya mbere ya Leta Zunze Ubumwe za Amerika GGG-P-463C. Inganda z’Abashinwa zikoresha GB/T 25994-2010 mu gutunganya no kohereza ibicuruzwa mu mahanga imbere mu gihugu. Ikigo mpuzamahanga gikunze gukurikiza amabwiriza ya ISO 5459:2015. Laboratwari zo gupima mu Bushinwa zikoresha JJG 117-2013 nk'uburyo bwo kugenzura.
Gusobanukirwa amahame ajyanye n'inganda zawe bifasha kwemeza ko ibisabwa mu bucuruzi mpuzamahanga byubahirizwa kandi bihuye n'ibyo ukeneye.
Umwanzuro: Urufatiro Rwizewe
Nubwo hari iterambere mu bijyanye no gupima hakoreshejwe laser, uburyo bwo gupima hakoreshejwe ikoranabuhanga, ndetse n'ikoranabuhanga ryo gupima, icyuma cyoroshye cyo hejuru cya granite gikomeje kuba ingenzi mu gukora neza. Guhuza kwayo no kudahindagurika k'ubushyuhe, imbaraga za mekanike, kurwanya ingese, no kugumana neza igihe kirekire bituma idasimburwa n'ibindi bikorwa byinshi.
Urufunguzo rwo guhitamo neza ni uguhuza urwego rw'ikarita n'imiterere yayo n'ibyo ukeneye by'ukuri. Ikarita idasanzwe yongera ikiguzi nta nyungu, mu gihe ikarita ntoya igabanya ubushobozi bwo gupima. Fata umwanya wo gusuzuma ibyo ukeneye mu buryo buboneye, maze uzasanga ufite igikoresho kizagufasha mu buryo bwizewe mu myaka ibarirwa muri za mirongo.
Waba urimo gushyiraho laboratwari nshya nziza, urimo gushyira ibikoresho mu imashini, cyangwa urimo gusimbuza ibikoresho bishaje, gusobanukirwa icyo plaque y'ubuso bwa granite itanga—n'ibisobanuro by'ingenzi ku mikoreshereze yawe—bigufasha gufata ibyemezo byo kugura bihuye n'ibyo ukeneye mu gupima neza.
Isahani yo hejuru yabonye umwanya wayo nk'igikoresho cy'ibanze mu gukora atari ukubera uburyo bugoye, ahubwo ari ukwizerwa. Iyo ukeneye indege y'icyitegererezo ushobora kwizera, granite iraguha — iri joro, umwaka utaha, n'imyaka ikurikira.
