Kwizicelo zokulinganisa ngokuchanekileyo ezibandakanya iipleyiti zomhlaba wegranite, amacandelo omatshini, kunye nezixhobo zokulinganisa, izinto ezininzi zobugcisa zinokuchaphazela kakhulu iziphumo zokulinganisa. Ukuqonda oku kuguquguquka kubalulekile ekugcineni ukuchaneka okungaqhelekanga ukuba izixhobo ze-metrology ezisekwe kwigranite zaziwa ngazo.
Eyona nto iphambili echaphazela ukuthembeka komlinganiselo kususela kukungaqiniseki okukhoyo kwezixhobo zokuhlola ngokwazo. Izixhobo ezichanekileyo eziphezulu ezifana namanqanaba e-elektroniki, i-laser interferometers, i-micrometers yedijithali, kunye ne-calipers eziphuculweyo zonke zithwala ukunyamezela okuchazwe ngumenzi onegalelo kuhlahlo lwabiwo-mali lokungaqiniseki. Nezixhobo zodidi oluphezulu zifuna ulungelelwaniso oluthe gqolo ngokuchasene nemigangatho evunyiweyo ukugcina amanqanaba achanekileyo achaziweyo.
Iimeko zokusingqongileyo zinika enye ingqwalasela enkulu. I-Granite i-coefficient yokwandisa i-thermal ephantsi kakhulu (ngokuqhelekileyo i-5-6 μm/m · ° C) ayisusi imfuno yokulawula ubushushu. Iindawo zokusebenzela ezineemitha zobushushu ezingaphezulu kwe-±1°C zinokubangela ukugqwetheka okunokumetwa kumphezulu wereferensi yegraniti kunye nendawo yokusebenza elinganiswayo. Iindlela ezingcono zoshishino zicebisa ukuba kugcinwe imo ezinzileyo yomlinganiselo wama-20°C ±0.5°C kunye nexesha elililo lolungelelwaniso kuwo onke amacandelo.
Ulawulo lokungcoliseka lumele into ehlala ijongelwa phantsi. I-sub-micron particulate matter iqokelelana kumphezulu womlinganiselo inokudala iimpazamo ezinokubonwa, ngakumbi xa kusetyenziswa iindlela zomlinganiso weflethi obonakalayo okanye we-interferometric. Indawo yokucoceka yeKlasi ye-100 ilungele eyona milinganiselo ibaluleke kakhulu, nangona iimeko zokusebenzela ezilawulwayo ezineeprothokholi zokucoca ezifanelekileyo zinokwanela kwizicelo ezininzi.
Ubuchwephesha bomqhubi bazisa omnye umaleko wokwahluka okunokwenzeka. Ukusetyenziswa kwamandla okulinganisa okufanayo, ukhetho olufanelekileyo lweprobe, kunye neendlela ezisemgangathweni zokumisa kufuneka zigcinwe ngokungqongqo. Oku kubaluleke ngakumbi xa kusenziwa umlinganiselo wamalungu angengomgangatho anokufuna ukulungiswa okulungiselelweyo okanye iindlela zomlinganiselo owodwa.
Ukuphunyezwa komgangatho opheleleyo weprothokholi kunokunciphisa le mingeni:
- Ulungelelwaniso lwezixhobo eziqhelekileyo ezilandelekayo ukuya kwi-NIST okanye eminye imigangatho eyaziwayo
- Iinkqubo zokujonga i-thermal kunye nembuyekezo yexesha langempela
- Iinkqubo zokulungiswa komphezulu wegumbi lokucoca
- Iinkqubo zesatifikethi soMsebenzisi kunye nokufaneleka ngamaxesha athile
- Uhlalutyo lokungaqiniseki komlinganiselo kwizicelo ezibalulekileyo
Iqela lethu lobuchwephesha libonelela:
• Iinkonzo zokuhlolwa kwecandelo leGranite zihambelana ne-ISO 8512-2
• Uphuhliso lwenkqubo yokulinganisa ngokwesiko
• Ukubonisana ngolawulo lokusingqongileyo
• Iinkqubo zoqeqesho lwabaSebenzisi
Ngemisebenzi efuna awona manqanaba aphezulu omlinganiselo wengqiniseko, sicebisa:
✓ Ukuqinisekiswa kwemihla ngemihla kwemiphezulu yereferensi ebalaseleyo
✓ Ulungelelwaniso lobushushu obuthathu kwizixhobo ezibalulekileyo
✓ Ukuqokelelwa kwedatha okuzenzekelayo ukunciphisa impembelelo yabasebenzisi
✓ Izifundo zonxulumano lwamaxesha ngamaxesha phakathi kweenkqubo zokulinganisa
Le ndlela yobugcisa iqinisekisa iinkqubo zakho zokulinganisa ezisekwe kwigranite zizisa iziphumo ezingaguqukiyo, ezithembekileyo ezihlangabezana nemigangatho yamazwe ngamazwe yokwenziwa ngokuchanekileyo kunye nosetyenziso lolawulo lomgangatho. Qhagamshelana neengcali zethu zemetroloji ukuze ufumane izisombululo ezilungiselelwe imingeni yakho yokulinganisa.
