Ni ubuhe buryo bwiza bwo gukora no kubungabunga amasahani y'ubuso bwa Granite?

Inyigisho ku bijyanye no gutunganya no kubungabunga icyuma gikozwe muri Granite: Igikoresho cyo gutunganya no gukoresha granite neza gisaba uburyo bwihariye bwo gutunganya no kugitunganya kugira ngo gikore neza kandi kirambe. Mbere yo kugitunganya, igice cya granite kigomba kubanza gutunganywa no kugitunganya mu buryo butambitse hashingiwe ku mahame y’impandeshatu. Nyuma yo gusya mu buryo butambitse, niba imashini ya CNC idashobora kugera ku buryo bunoze busabwa—ubusanzwe ikagera ku buryo bunoze bwa Granite 0 (0.01mm/m nk'uko bivugwa muri DIN 876)—gusoza intoki biba ngombwa kugira ngo hagerwe ku manota yo hejuru y’ubuhanga nka Granite 00 (0.005mm/m2 yo kwihanganira buri wese hakurikijwe ibipimo bya ASTM B89.3.7).

Uburyo bwo gukora imashini bugira intambwe nyinshi z'ingenzi. Ubwa mbere, gusya neza bishyiraho uburyo bw'ibanze bwo kugorora, hagakurikiraho uburyo bwa kabiri bwo kurangiza kugira ngo haveho ibimenyetso byo gukora imashini. Gusya neza, akenshi bikorwa n'intoki, binoza ubuso kugira ngo hagerwe ku buryo bukwiye bwo kwihanganira ubugorora n'ubugororangingo (agaciro ka Ra ka 0.32-0.63μm, aho Ra igereranya ikigereranyo cy'ubuso). Hanyuma, igenzura ryimbitse rituma hubahirijwe amahame ya tekiniki, aho ibipimo bishyirwa ku murongo w'impande, impande, n'imirongo yo hagati—ubusanzwe amanota 10-50 bitewe n'ingano y'icyuma—kugira ngo harebwe ko hari isuzuma ry'ubuziranenge bungana.

Gufata no gushyiraho bigira ingaruka zikomeye ku buryo bunoze. Bitewe n'ubudahangarwa bw'ibuye rya granite (ubukana bwa Mohs 6-7), guterura nabi bishobora gutera imihindagurikire ihoraho. Ku bikorwa by'ingenzi bisaba ubuziranenge bwa Grade 00, gushyiramo intoki nyuma yo gushyiraho ni ingenzi kugira ngo hagarurwe ubuziranenge bwangiritse mu gihe cyo gutwara. Uku kwita ku tuntu duto bitandukanya amasahani y'ubuso bwa granite y'ubuziranenge n'ay'imashini zisanzwe.

Uburyo bwo kubungabunga bigira ingaruka ku mikorere n'igihe cy'ubuzima. Tangira no gusukura neza ukoresheje isuku ya pH idafite aho ibogamiye—wirinde ibintu bihumanya bishobora gukata ubuso. Gupima buri mwaka ukoresheje laser interferometers, ikurikije amahame ya NIST, bituma habaho ubuziranenge bukomeza. Mu gushyira ibikoresho byo gukora, reka ubushyuhe buhuze (ubusanzwe iminota 15-30) kugira ngo wirinde amakosa yo gupima aturutse ku gutandukana kw'ubushyuhe. Ntukigere ushyira ibintu bikomeye hejuru y'ubuso, kuko ibi bishobora gutera uduheri duto dutuma ubugari bugabanuka.

Amabwiriza akwiye yo gukoresha arimo kubahiriza imipaka y’imitwaro kugira ngo hirindwe kwangirika kw’inyubako, kubungabunga ibidukikije bihamye (ubushyuhe 20±2°C, ubushuhe 50±5%), no gukoresha ibikoresho byabugenewe byo guterura kugira ngo hirindwe kwangirika kw’indege. Bitandukanye n’ibindi byuma, ubushyuhe bwa granite (0.01ppm/°C) bugabanya ingaruka ku bidukikije, ariko impinduka zitunguranye z’ubushyuhe zigomba kwirindwa.

Nk'igikoresho cy'ibanze mu gupima neza, amasafuriya y'ubuso bw'ibuye yemewe (ISO 17025 yemewe) ni yo akoreshwa nk'icyitegererezo cy'ibipimo by'ingano. Kubungabunga kwayo bisaba imbaraga nke - guhanagura gusa n'igitambaro kidafite ibara nyuma yo kuyikoresha - nta mavuta cyangwa amavuta adasanzwe akenewe. Mu gukurikiza aya mabwiriza yo gutunganya no kwitaho, amasafuriya y'ubuso bw'ibuye yemewe atanga imikorere yizewe mu myaka ibarirwa muri za mirongo, bigatuma aba ingenzi cyane muri laboratwari zo gupima, mu nganda zikora indege, no mu buhanga buhanitse.
