Ibisabwa mu bya tekiniki n'amabwiriza agenga imikoreshereze y'amasahani y'ubuso bwa granite

Amasahani yo hejuru ya granite ni inkingi ikomeye mu gupima neza, akoreshwa cyane muri laboratwari no mu nganda nk'ishingiro ry'ibikoresho byo kugenzura, ibikoresho byo hejuru, n'ibice bya mekanike. Akozwe mu mabuye meza kandi asanzwe, aya masahani ahuza ibyiza nyabyo by'amabuye hamwe n'ubudahangarwa budasanzwe, atanga imikorere myiza kurusha amasahani asanzwe y'icyuma gishongeshejwe.

Buri gice cy'ubuso bwa granite gikorwa binyuze mu guhuza uburyo bwo gukora neza no gusya neza intoki, akenshi mu bushyuhe buhoraho kugira ngo habeho ubuziranenge buhagije. Umusaruro ni ubuso bworoshye, burambuye kandi bufite imiterere myiza, ubwiza bw'umukara, n'imiterere imwe. Uku guhuza ubwiza n'ubuziranenge bituma granite iba ibikoresho bidasimburwa byo gupima no kugenzura neza.

Kugira ngo hagerwe kuri ubwo buryo bwiza kandi bukomeze, ibyuma byo hejuru bya granite bigomba kuba byujuje ibisabwa n'ibipimo ngenderwaho by'ibikoresho n'inganda. Ibuye rikoreshwa rigomba kuba rifite imiterere myiza kandi rinini—rikunze kuba gabbro, diabase, cyangwa granite y'umukara—rifite biotite iri munsi ya 5%, amazi arenga 0.25%, kandi rikagira modulus ireshya na 0.6 × 10⁻⁴ kg / cm². Ubukana bw'ubuso bugomba kuba burenga 70 HS kugira ngo habeho ubudahangarwa bwiza bwo kwangirika. Mu gihe cyo gukora, ubuso bugomba kuba budafite burundu imyanya, imyobo, imyobo y'umwuka, cyangwa ibintu bitagira aho bibogamiye. Inenge ntoya zo mu rwego rwo kwisiga zidahindura uko ibintu bimeze zishobora kwemerwa, ariko inenge iyo ari yo yose ku buso bwo gupima ishobora kugira ingaruka ku musaruro irabujijwe cyane.

Bitandukanye n'amasahani y'icyuma gikozwe mu cyuma, amasahani y'ubuso bwa granite ntafite ingufu za rukuruzi, arwanya ingese, kandi nta ngaruka ku bushyuhe cyangwa ubushuhe buhindagurika. Agumana ubugari mu gihe kirekire kandi ntakunze kwangirika cyangwa guhinduka. Nubwo yangirika, granite ishobora gushwanyagurika gato gusa ntagire ingaruka ku busugire cyangwa ubuziranenge bw'ubuso. Uku kuramba guha granite inyungu ikomeye mu bidukikije bisaba gupima neza kandi neza.

Ku byerekeye ibyuma byo hejuru, nka Grade 000 na Grade 00, ibikoresho byo gufata nk'imigozi yo guterura muri rusange ntibisabwa kugira ngo hirindwe kugira ingaruka ku buryo ubuso bukorerwaho bukora neza. Niba hakenewe imigozi cyangwa imiyoboro ifite insinga ku mapine yo mu cyiciro cya 0 cyangwa Grade 1, uburebure bwabyo bugomba kuguma munsi y'ubutaka kugira ngo hirindwe ko bihinduka. Ubuso bwemewe (Ra) bw'ubuso bukorerwaho ubusanzwe buri hagati ya 0.32 na 0.63 μm, mu gihe impande zishobora kugera kuri 10 μm. Byongeye kandi, ubushobozi bwo kwihanganira impande zegeranye bukurikiza ibipimo bya GB/T1184 Grade 12, bigatuma habaho isano nyayo hagati y'ubuso bwose bupimwa.

Gukoresha no kubungabunga neza amasafuriya y’ubuso bwa granite ni ingenzi cyane mu kubungabunga ubuziranenge bw’amasafuriya y’ubuso. Agomba gukoreshwa ahantu hasukuye kandi hagenzurwa ubushyuhe, arinzwe ingaruka, kandi agasukurwa buri gihe kugira ngo akurweho ivumbi n’imyanda. Iyo afashwe neza, amasafuriya y’ubuso bwa granite atanga ubuziranenge budasanzwe kandi aramba, akaba ari umusingi wizewe wo gupima no kugenzura neza mu nganda zigezweho.

Muri ZHHIMG, twibanda ku gukora no gupima neza amasahani y’ubuso bwa granite yujuje ibisabwa mpuzamahanga. Uburyo bwacu bwo gukora buteye imbere, kugenzura ubuziranenge, no gukora byemejwe na ISO bitanga umusaruro uhamye kandi utanga umusaruro wizewe n’abahanga na laboratwari ku isi yose.
