Ekukhiqizeni ngokunemba, ekulinganisweni kwamathuluzi omshini, kanye nokufakwa kwemishini, imiphetho ye-granite isebenza njengamathuluzi okubhekisela abalulekile ekulinganiseni ukuthamba kanye nokuqina kwamatafula okusebenza, imigqa yokuqondisa, kanye nezingxenye ezinembile kakhulu. Ikhwalithi yabo inquma ngqo ukunemba kokulinganisa okulandelayo kanye nezinqubo zokukhiqiza. Njengomhlinzeki womhlaba wonke othembekile wamathuluzi okulinganisa i-granite ngokunemba, i-ZHHIMG izinikele ekusizeni amakhasimende ukuba abe yingcweti ezindleleni zokuhlola ikhwalithi yobungcweti zemiphetho ye-granite ngokunemba—ukuqinisekisa ukuthi ukhetha imikhiqizo ethembekile ehlangabezana nezidingo zokunemba zesikhathi eside.
1. Kungani Ikhwalithi Ye-Granite Straightedge Ibalulekile
I-granite ithandwa kakhulu ekukhiqizeni i-straightedge ngenxa yezinzuzo zayo ezingokwemvelo: ukumuncwa kwamanzi okuphansi kakhulu (0.15%-0.46%), ukuzinza okuhle kakhulu kobukhulu, kanye nokumelana nokugqwala kanye nokuphazamiseka kwamagnetic. Kodwa-ke, amaphutha emvelo amatshe (isb., imifantu yangaphakathi) noma ukucubungula okungafanele kungonakalisa ukusebenza kwayo. I-straightedge ye-granite esezingeni eliphansi ingaholela emaphutheni okulinganisa, ukungahambisani kahle kwemishini, ngisho nokulahlekelwa kokukhiqiza. Ngakho-ke, ukuhlolwa kwekhwalithi okuphelele ngaphambi kokuthenga noma ukusebenzisa kubalulekile.
2. Izindlela Zokuhlola Ikhwalithi Eyinhloko Yezingqimba Ze-Granite
Ngezansi kunezindlela ezimbili eziqashelwa embonini, ezisebenzayo zokuhlola ikhwalithi ye-granite straightedge—ezifanele ukuhlolwa endaweni, ukuqinisekiswa kwezinto ezingenayo, noma ukuhlolwa kokulungiswa okuvamile.
2.1 Ukuhlolwa Kokuthungwa Nobuqotho Betshe (Ukuhlolwa Kwe-Acoustic)
Le ndlela ihlola isakhiwo sangaphakathi kanye nobuningi be-granite ngokuhlaziya umsindo okhiqizwayo lapho uthinta indawo—indlela enembile yokuthola amaphutha afihliwe njengemifantu yangaphakathi noma ukuthungwa okuxekethile.
Izinyathelo Zokuhlola:
- Ukulungiselela: Qinisekisa ukuthi i-straightedge ibekwe endaweni ezinzile, eyisicaba (isb., ipulatifomu yemabula) ukuze ugweme ukuphazamiseka komsindo wangaphandle. Ungathinteli indawo yokulinganisa ngokunemba (ukuvimbela imihuzuko); gxila emaphethelweni angasebenzi kahle noma phansi kwe-straightedge.
- Indlela Yokuthinta: Sebenzisa ithuluzi elincane, elingelona elensimbi (isb. isando serabha noma ithawula lokhuni) ukuze uthinte i-granite kancane ezindaweni ezi-3-5 ezilinganayo ngobude bomphetho oqondile.
- Ukwahlulela Okuhle:
- Okufanelekile: Umsindo ocacile, ozwakalayo ubonisa isakhiwo sangaphakathi esifanayo, ukwakheka kwamaminerali aminyene, futhi akukho mifantu efihliwe. Lokhu kusho ukuthi i-granite inobulukhuni obuphezulu (Mohs 6-7) kanye namandla omshini, afanele ukusetshenziswa ngokunemba.
- Okungafaneleki: Umsindo ongathintiwe, ongabonakali usikisela amaphutha angaphakathi angaba khona—njengemifantu emincane, ukubopha okuxekethile, noma ubuningi obungalingani. Ama-straightedge anjalo angase aguquguquke ngaphansi kokucindezeleka noma alahlekelwe ukunemba ngokuhamba kwesikhathi.
Inothi Eliyinhloko:
Ukuhlolwa kwe-acoustic kuyindlela yokuhlola yokuqala, akuyona indlela emele yodwa. Kumelwe kuhlanganiswe nezinye izivivinyo (isb., ukumuncwa kwamanzi) ukuze kuhlolwe ngokuphelele.
2.2 Ukuhlolwa Kokumuncwa Kwamanzi (Ukuhlolwa Kokujiya Nokusebenza Okungangeni Manzi)
Ukumuncwa kwamanzi kuyinkomba ebalulekile ye-指标 (inkomba) yemiphetho eqondile ye-granite—ukumuncwa okuncane kuqinisekisa ukuzinza ezindaweni zokusebenzela ezinomswakama futhi kuvimbela ukuwohloka okunembile okubangelwa ukwanda komswakama.
Izinyathelo Zokuhlola:
- Ukulungiswa Komphezulu: Abakhiqizi abaningi bafaka ungqimba lwamafutha oluvikelayo ezinhlangothini eziqondile ze-granite ukuvimbela ukubola ngesikhathi sokugcina. Ngaphambi kokuhlola, sula umphezulu kahle ngesihlanzi esingathathi hlangothi (isb., i-isopropyl alcohol) ukuze ususe zonke izinsalela zamafutha—ngaphandle kwalokho, uwoyela uzovimba ukungena kwamanzi futhi uphazamise imiphumela.
- Ukuhlolwa Kokusebenza:
- Lahla amaconsi angu-1-2 amanzi acwengekile (noma uyinki, ukuze ubone ngokucacile) endaweni engaqondile yomphetho oqondile.
- Yiyeke ime imizuzu emi-5-10 ekushiseni kwegumbi (20-25℃, umswakama ongu-40%-60%).
- Ukuhlolwa Kwemiphumela:
- Okufanelekile: Iconsi lamanzi lihlala liphelele, ngaphandle kokusabalala noma ukungena egranite. Lokhu kusho ukuthi i-straightedge inesakhiwo esiminyene, esinokumuncwa kwamanzi okungu-≤0.46% (kuhlangabezana nezindinganiso zemboni zamathuluzi egranite anembile). Imikhiqizo enjalo igcina ukunemba ngisho nasezimweni ezinomswakama.
- Okungafaneleki: Amanzi asakazeka noma angene ngokushesha etsheni, abonisa ukumuncwa kwamanzi okuphezulu (>0.5%). Lokhu kusho ukuthi i-granite inezimbobo, ithambekele ekuguqukeni okubangelwa umswakama, futhi ayifaneleki ukulinganiswa ngokunemba kwesikhathi eside.
Isilinganiso Semboni:
Ama-straightedge e-granite asezingeni eliphezulu (njengalawo avela ku-ZHHIMG) asebenzisa izinto zokusetshenziswa ze-granite zekhwalithi ephezulu ezilawulwa ukumuncwa kwamanzi phakathi kuka-0.15% no-0.3% — ngaphansi kakhulu kwesilinganiso semboni, okuqinisekisa ukuzinza kwemvelo okumangalisayo.
3. Ukuqinisekiswa Kwekhwalithi Okwengeziwe: Ukubekezelelana Okuphelele Nokuhambisana Nezindinganiso
I-granite yemvelo ingaba neziphambeko ezincane (isb., izimbobo ezincane, ukuhlukahluka okuncane kombala), kanti amanye amaphutha okucubungula (isb., ama-chips amancane emaphethelweni angasebenzi) ayamukeleka uma ehlangabezana nezindinganiso zomhlaba wonke. Nakhu okufanele ukuhlole:
- Ukulungiswa Okuphelele Kwesici: Ngokusho kwe-ISO 8512-3 (izinga lamathuluzi okulinganisa i-granite), amaphutha amancane ebusweni (indawo ≤5mm², ukujula ≤0.1mm) angalungiswa nge-epoxy resin enamandla aphezulu, enganciphisi—uma nje ukulungiswa kungathinti ukuthamba noma ukuqondile kwe-straightedge.
- Isitifiketi Sokunemba: Cela umbiko wokulinganisa kumkhiqizi, oqinisekisa ukuthi i-straightedge ihlangabezana nezidingo zebanga (isb., Ibanga 00 lokunemba okuphezulu, Ibanga 0 lokunemba okuvamile). Umbiko kufanele ufake idatha mayelana nephutha lokunemba (isb., ≤0.005mm/m yeBanga 00) kanye nokuba yisicaba.
- Ukulandeleka Kwezinto Ezibonakalayo: Abaphakeli abathembekile (njenge-ZHHIMG) banikeza izitifiketi zezinto ezibonakalayo, eziqinisekisa imvelaphi ye-granite, ukwakheka kwamaminerali (isb., i-quartz ≥60%, i-feldspar ≥30%), kanye namazinga emisebe (≤0.13μSv/h, okuhambisana nezindinganiso zokuphepha ze-EU CE kanye ne-US FDA Class A).
4. I-ZHHIMG's Granite Straightedge: Ikhwalithi Ongayethemba
Kwa-ZHHIMG, sibeka phambili ukulawulwa kwekhwalithi kuyo yonke inqubo yokukhiqiza—kusukela ekukhetheni izinto zokusetshenziswa kuya ekugayeni ngokunemba—ukuletha ama-straightedges adlula amazinga omhlaba wonke:
- Izinto Zokusetshenziswa Ezisezingeni Eliphezulu: Zitholakala ezimayini ze-granite ezisezingeni eliphezulu eShayina naseBrazil, ngokuhlolwa okuqinile ukuze kususwe amatshe anezimfa zangaphakathi noma amanzi amaningi.
- Ukucubungula Ngokucophelela: Kufakwe imishini yokugaya ye-CNC (ukunemba ± 0.001mm) ukuqinisekisa iphutha lokunemba ≤0.003mm/m kuma-straightedge ebanga le-00.
- Ukuhlolwa Okuphelele: Yonke i-straightedge ihlolwa nge-acoustic, ukuhlolwa kokumuncwa kwamanzi, kanye nokulinganiswa nge-laser ngaphambi kokuthunyelwa—kunikezwe isethi ephelele yemibiko yokuhlolwa.
- Ukwenza ngokwezifiso: Ukusekelwa kobude obungokwezifiso (300mm-3000mm), izingxenye eziphambeneyo (isb., uhlobo lwe-I, unxande), kanye nokubhoboza imigodi yokufakwa kwezinto.
- Isiqinisekiso Sangemva Kokuthengisa: iwaranti yeminyaka emi-2, insizakalo yokulungisa kabusha yamahhala ngemuva kwezinyanga eziyi-12, kanye nokusekelwa kobuchwepheshe endaweni yamakhasimende omhlaba wonke.
Kungakhathaliseki ukuthi udinga i-granite straightedge yokulinganisa ithuluzi lomshini i-导轨 (guide rail) noma ukufakwa kwemishini, ithimba lochwepheshe le-ZHHIMG lizokusiza ukhethe umkhiqizo ofanele. Xhumana nathi manje ukuze uthole isampula yokuhlola yamahhala kanye nesilinganiso esenziwe ngokwezifiso!
