Isahani ya granite ni urufatiro rwo gupima neza, ikoreshwa cyane muri laboratoire no mu nganda zikora nk'ibikoresho byo kugenzura ibikoresho, ibikoresho bisobanutse, n'ibikoresho bya mashini. Ikozwe muri granite yo mu rwego rwohejuru, isahani ihuza ibyiza byumubiri byamabuye hamwe nuburinganire budasanzwe, bitanga imikorere isumba ibyuma bisanzwe.
Buri isahani ya granite ikorwa hifashishijwe uburyo bwo gutunganya neza no gusya intoki neza, mubisanzwe mubihe byubushyuhe buhoraho kugirango hamenyekane neza. Igisubizo ni cyoroshye, kiringaniye gikora hamwe nuburyo bwiza-bwuzuye, imiterere yumukara, hamwe nuburyo bumwe. Uku guhuza ubwiza nubusobanuro butuma granite ibintu bidasimburwa kubikorwa byo gupima neza no gukora kalibrasi.
Kugirango ugere no kubungabunga ibyo bisobanuro, isahani ya granite igomba kuba yujuje ibikoresho bikomeye ninganda. Ibuye ryakoreshejwe rigomba kuba rifite ingano kandi yuzuye - ubusanzwe gabbro, diabase, cyangwa granite yumukara - hamwe na biotite iri munsi ya 5%, kwinjiza amazi munsi ya 0,25%, hamwe na moderi ya elastike irenga 0,6 × 10⁻⁴ kg / cm². Ubukomere bwubuso bugomba kuba hejuru ya 70 HS kugirango wirinde kwambara neza. Mugihe cyo kubyara umusaruro, ubuso bukora bugomba kuba butarangwamo ibice, imyenge, imyobo yo mu kirere, cyangwa ibishishwa. Amakosa mato yo kwisiga adahindura ukuri arashobora kwemerwa, ariko inenge iyo ari yo yose yo gupima ishobora kugira ingaruka kubisubizo irabujijwe rwose.
Bitandukanye n'ibyuma bikozwe mu cyuma, isahani ya granite ntabwo ari magnetique, irwanya ruswa, kandi ntigira ingaruka ku ihindagurika ry'ubushyuhe cyangwa n'ubushuhe. Zigumana uburinganire hejuru yo gukoresha igihe kirekire kandi ntabwo zikunda ingese cyangwa guhinduka. Nubwo bigira ingaruka, granite irashobora gukata gato gusa itagize ingaruka kubusugire cyangwa ukuri kwubuso. Uku kuramba guha granite inyungu zifatika mubidukikije bisaba ibipimo bihamye, bihanitse neza.
Kuri plaque yo hejuru-isahani yo hejuru, nka Grade 000 na Grade 00, gufata ibintu nkibikoresho byo guterura muri rusange ntibisabwa kwirinda kugira ingaruka kumikorere. Niba insinga zometseho cyangwa ibishishwa bikenewe ku byapa byo mu cyiciro cya 0 cyangwa icyiciro cya 1, ubujyakuzimu bwabyo bugomba kuguma munsi yindege yo hejuru kugirango birinde kugoreka. Ubuso bwemewe (Ra) bwubuso bwakazi busanzwe buri hagati ya 0.32 na 0,63 mm, mugihe impande zishobora kugera kuri 10 mm. Byongeye kandi, kwihanganira perpendicularity kumpande zegeranye bihuye na GB / T1184 Icyiciro cya 12 cyicyiciro cya 12, byemeza isano ya geometrike neza mubipimo byose bipima.
Gukoresha neza no kubungabunga ni ngombwa kugirango ubungabunge neza ibyapa bya granite. Bagomba gukoreshwa ahantu hasukuye, hagenzurwa nubushyuhe, bakarindwa ingaruka, kandi bagasukurwa buri gihe kugirango bakureho ivumbi n imyanda. Iyo bikozwe neza, isahani ya granite itanga urugero rutagereranywa rwo kuramba no kuramba, bikora nk'ishingiro ryizewe ryo gupima no kugenzura neza neza mu nganda zigezweho.
Muri ZHHIMG, tuzobereye mu gukora no guhinduranya neza ibyapa bya granite byuzuye byujuje ubuziranenge mpuzamahanga. Ibikorwa byacu byateye imbere, kugenzura ubuziranenge, hamwe n’umusaruro wemejwe na ISO byemeza ko isahani ya granite itanga ubunyangamugayo burambye kandi bwizewe na ba injeniyeri na laboratoire ku isi.
