Emkhakheni wobunjiniyela bokucacisa kanye ne-metrology, izingxenye zokunemba ze-granite—njengezingcwecwe zobuso, izisekelo zomshini, namatafula optical—zihlonishwa ngokuqina kwazo okumangalisayo, ubulukhuni, kanye nokumelana nokugqwala. Ingxenye ye-granite esezingeni eliphezulu, uma inakekelwa kahle, ingagcina ukulinganiswa kwayo kanye nokuba yisicaba amashumi eminyaka, isebenza njengesisekelo esingaguquki sezilinganiso zakho ezibaluleke kakhulu. Kodwa-ke, ngisho ne-granite eqinile kakhulu ayivikelekile emathonyeni amancane endawo yayo kanye nokusetshenziswa kwayo. Ukugcina ukulinganiswa kwesikhathi eside akuyona into eyenzeka kanye kuphela; kuyisifundo esiqhubekayo esidinga ukuqonda okujulile kokulawulwa kwemvelo, ukuphathwa ngokucophelela, kanye nenqubo yokulungisa eqhubekayo.
Ukuqonda i-Environmental Foundation
Isitha esikhulu sokulinganiswa kwesikhathi eside akusikho ukuguguleka kwansuku zonke, kodwa indawo engalawulwa. Ukuqinisekisa ukuthi izingxenye zakho ze-granite zigcina ukunemba kwazo kwezinga le-micron, kufanele uqale wakhe isisekelo esiqinile esibonakalayo.
Izinga lokushisa liyinguquko ebaluleke kakhulu. I-Granite ine-coefficient ephansi kakhulu yokwanda kokushisa, kodwa akuyona i-zero. Ukuze kube namazinga aphezulu okunemba, izingxenye kufanele zigcinwe elebhu ye-metrology elawulwa ukushisa, okungcono igcinwe ku-20°C (±2°C). Ukushintshashintsha kwezinga lokushisa okungazelelwe noma ukuchayeka ngqo elangeni, emithonjeni yomoya opholile, kanye nemigudu yokushisa kungabangela i-gradient yokushisa yendawo. Lezi gradient zidala ukucindezeleka kwangaphakathi ngaphakathi kwetshe, okuholela ekuguqukeni kwesikhashana kodwa okuphawulekayo okulimaza ukunemba kokulinganisa. Ngaphezu kwalokho, izingcezu zomsebenzi ezinkulu noma amabhlogo e-gauge kufanele avunyelwe ukuthi avumelane nobuso be-granite amahora amaningana ngaphambi kokulinganisa ukuvimbela ukudluliselwa kokushisa emiphumeleni egobile.
Okubaluleke ngokulinganayo isisekelo sokufakwa. Ingxenye yegranite izinzile kuphela njengalokho ehlezi kukho. Kumele ibekwe esisekelweni esiqinile, esingenazo izithithi. Ezilungiselelweni ezinembe kakhulu, lokhu kuvame ukusho ukusebenzisa ama-pad okuzihlukanisa okunamandla noma okuphefumula ukuze kuhlukaniswe igranite ekudlidlizeni phansi okubangelwa imishini eseduze, ama-forklift, noma ngisho nokuhamba ngezinyawo. Uma ufaka ipuleti elikhulu elingaphezulu, ukusekelwa okufanele akuxoxiswani ngakho. Kufanele kuhlale ohlelweni lokusekela olunamaphuzu amathathu noma amahlanu (ngokuvamile amaphuzu amathathu ayinhloko akha unxantathu we-isosceles kanye namaphuzu amabili asizayo). Lokhu kulungiselelwa kuvimbela ukucindezeleka kwangaphakathi kanye "nokuzamazama," okuqinisekisa ukuthi ipuleti lihlala esimweni salo semvelo, esingenazo izithithi. Ngemva kokulinganisa kokuqala, kunconywa kakhulu ukuthi ingxenye ihlale ingaphazanyiswa amahora angu-12 kuya kwangu-24 ukuze kuvunyelwe noma yikuphi ukucindezeleka okusele ukuthi kunyamalale ngaphambi kokuthatha ukufundwa kokugcina kokulinganisa.
Ukuphathwa Kwansuku Zonke kanye Nemikhuba Emihle Yokusebenza
Uma indawo ilawulwa, ubude bokulinganiswa kwe-granite yakho buxhomeke kakhulu endleleni ephathwa ngayo phakathi nokusebenza kwansuku zonke. Ubuso bepuleti le-granite buyimpahla yalo eyigugu kakhulu, futhi ukuyivikela ekulimaleni ngokomzimba kubaluleke kakhulu.
Njalo qiniseka ukuthi ubuso be-granite buhlanzekile ngokuphelele ngaphambi nangemva kokusebenzisa. Uthuli, ama-chip ensimbi, kanye nezinhlayiya eziklwebhayo yizona zimbangela eziphambili zokuklwebheka kobuso. Sebenzisa indwangu ethambile, engena-lint emanziswe kancane ngesihlanzi se-pH esingathathi hlangothi noma utshwala obuhlanzekile kakhulu ukuze usule ubuso. Gwema izinyibilikisi zamakhemikhali ezinzima noma izixazululo ze-alkaline, njengoba zingaguguleka kancane ubuso betshe ngokuhamba kwesikhathi. Uma ubeka izinto zokusebenza epuletini, ungalokothi uzishelele noma uzihudule. Esikhundleni salokho, ziphakamise bese uzibeka phansi ngobumnene. Ngezingxenye ezisindayo, sebenzisa ama-jack noma ama-hoist alungisekayo ukuze usabalalise isisindo ngokulinganayo futhi uvimbele imithwalo egxilile engabangela ukucindezeleka noma ukuqhekeka kwendawo.
Kubalulekile futhi ukukhumbula ukuthi ipuleti lobuso le-granite aliyona yini. Akuyona ibhentshi lomsebenzi, i-anvil, noma indawo yamanye amathuluzi. Ungalokothi usebenzise indawo yokubhala, ukubhoboza, noma njengesisekelo semisebenzi yemishini esindayo engabangela umonakalo. Ngaphezu kwalokho, izingcezu zomsebenzi ezisebenza ngomagnetic kufanele zisuswe kumagnet ngaphambi kokufakwa epuletini. I-magnetism eseleyo ingadonsela izinhlayiya zensimbi ezincane emoyeni, ezingabe sezisebenza njengesiqhumane ngaphansi kwengxenye ehambayo, ziklwebhe ubuso obunembile kancane.
Ukulungiswa Okusebenzayo kanye Nokulungiswa Kwezikhathi Ezithile
Ngisho noma kunezilawuli zemvelo eziphelele kanye nokuphathwa ngobumnene, ukulinganiswa kwesikhathi eside kudinga isimiso sokunakekelwa esihlelekile. I-Granite iyinto yemvelo, futhi eminyakeni eminingi, ingabhekana nokushintshashintsha okuncane ngenxa yokukhukhuleka noma ukuqina kwezinto. Ngakho-ke, ukuthembela kuphela ekulinganisweni kokuqala kwefektri kuyingozi okufanele ithathwe yilebhu yokucacisa.
Sebenzisa inqubo yokuqinisekisa esezingeni eliphezulu. Nsuku zonke noma masonto onke, opharetha kufanele benze ukuhlolwa okusheshayo kokubona umonakalo womphezulu kanye nokuhlolwa okuyisisekelo kokuthamba besebenzisa izinga lomoya oqondile noma umphetho oqondile olinganisiwe. Lokhu kusiza ekubambeni noma yiziphi izinkinga ezisheshayo noma ukushintsha okukhulu.
Ukuze uthole ukulinganiswa kwesikhathi eside kwangempela, hlela ukulinganiswa kabusha okusemthethweni ngezikhathi ezijwayelekile, ngokuvamile njalo ezinyangeni eziyi-6 kuya kweziyi-12, kuye ngokuthi ukusetshenziswa kuphindwe kangaki kanye namazinga okubekezelelana adingekayo. Le nqubo kufanele iqhutshwe ochwepheshe be-metrology abaqeqeshiwe besebenzisa imishini elandelekayo, njengezinsimbi ze-elekthronikhi ezinezinga eliphezulu noma ama-interferometer e-laser. Phakathi nale nqubo, lonke ubuso buyaskenwa (ngokuvamile ngephethini yegridi noma "yenkanyezi") ukuze kukhiqizwe imephu ephelele ye-topographic yepuleti. Uma kutholakala ukuphambuka okuncane, ochwepheshe abanekhono bavame ukwenza ukulungisa noma ukuklwebha endaweni ukuze babuyisele ubuso ebangeni labo lokuqala le-DIN noma le-ISO.
Ngokulawula imvelo ngokuqinile, ukuphoqelela izinqubo zokuphatha eziqinile, nokuzibophezela ohlelweni lokulungiswa kabusha kobungcweti, uqinisekisa ukuthi izingxenye zakho zokunemba kwe-granite zihlala ziyisilinganiso esithembekile. Lokhu kuzinikela akuvikeli nje kuphela ukutshalwa kwezimali kwakho kodwa, okubaluleke kakhulu, kuqinisekisa ubuqotho nokuthembeka kwazo zonke izilinganiso ezikhiqizwa yiqembu lakho.
