Okokuqala, izinzuzo zesisekelo se-granite
1. Ukuqina okuphezulu nokuzinza
I-Granite ine-high density (2.6-3.1g / cm³), futhi i-modulus ye-Young (i-elastic modulus) ingafinyelela ku-50-100 GPa, ephakeme kakhulu kunensimbi evamile (cishe i-200 GPa), kodwa ngenxa ye-isotropic crystal structure, cishe ayinayo i-deformation yepulasitiki ekusetshenzisweni kwesikhathi eside. Uma kuqhathaniswa nezinto zensimbi, i-granite yokwandisa ukushisa kwe-thermal coefficient iphansi kakhulu (cishe 5×10⁻⁶/℃), endaweni yokuguquguquka kwezinga lokushisa isengakwazi ukugcina ukuqina okuhle kakhulu kwe-dimensional, igweme ngenxa yokwanda okushisayo ukusikwa okubandayo kuthinta ukunemba kwemishini.
2. Ukusebenza okuhle kakhulu kokunciphisa ukudlidliza
Isakhiwo sekristalu sangaphakathi se-granite sinokudambisa okuphezulu kwangaphakathi, okukwazi ukumunca ngempumelelo ukudlidliza kwe-high-frequency futhi kunciphise i-resonance phenomenon. Uma kuqhathaniswa nesisekelo sensimbi, igwala linamandla okunciphisa ukudlidliza okunamandla ebangeni elingu-20Hz-1kHz, lihlinzeka ngendawo yokuqala "ehlanzekile" yohlelo olusebenzayo lokuhlukanisa lokudlidliza nokunciphisa umthwalo wokulawula okusebenzayo okulandelayo.
3. Ukumelana nokugqwala, okungewona uzibuthe, ukusebenziseka okubanzi
Ukuzinza kwamakhemikhali egwadle, ukumelana nokugqwala kwe-asidi ne-alkali, ngeke kugqwale noma kufakwe i-oxidation, ifanele igumbi elihlanzekile, umswakama ophezulu noma indawo egqwalayo. Ngaphezu kwalokho, i-granite iwumsebenzi ongewona uzibuthe, ngeke iphazamise amathuluzi anembayo (njenge-electron microscopy, imishini yokulinganisa kazibuthe, njll.), ifanele izimo zohlelo lokusebenza ezizwelayo zikagesi.
4. Impilo ende yesevisi, izindleko eziphansi zokunakekela
Ukuqina kwe-Granite kuphezulu (ubunzima be-Mohs 6-7), ukumelana nokugqoka, ukusetshenziswa kwesikhathi eside akulula ukugqoka noma ukuguqulwa, impilo yesevisi ingafinyelela eminyakeni engaphezu kwengu-20. Uma kuqhathaniswa nezinto zensimbi, ayidingi ukwelashwa okuvamile okulwa nokugqwala noma ukugcotshwa, futhi izindleko zokuyilungisa ziphansi kakhulu.
5.I-flatness ephezulu kanye nokuqedwa kwendawo
Ngokugaya okunembayo nokupholishwa, ukucaba kwesisekelo segwadle kungafinyelela ku-0.005mm/m², kanye nobulukhuni bobuso obungu-Ra≤0.2μm, okuqinisekisa ukulingana okuhle nezisetshenziswa ezinembayo (njengeplathifomu yokubona, i-laser interferometer) nokunciphisa amaphutha omhlangano.
Okwesibili, ukushiyeka kwesisekelo se-granite
1. Isisindo esikhulu, okunzima ukusithwala nokusifaka
I-Granite inomthamo omkhulu futhi inzima kune-aluminium noma insimbi ngosayizi ofanayo, okwenza ukubamba nokufakwa kwamapulatifomu amakhulu kudinga imishini ekhethekile (njengama-forklift noma amathuluzi okuphakamisa), ukwandisa izindleko zokuthumela.
2. I-brittleness ephezulu, ukumelana nomthelela obuthakathaka
Nakuba igwadle linobulukhuni obuphezulu, liyinto ephukayo futhi ingase iqhekeke noma iwe lapho ingaphansi komthelela oqinile (njengokuwa noma ukungqubuzana). Ngakho-ke, ukunakekelwa okwengeziwe kufanele kuthathwe ngesikhathi sokuthutha nokufakwa ukuze kugwenywe ukudlidliza okukhulu noma umthelela.
3. Ukucubungula kunzima futhi izindleko zokwenza ngokwezifiso ziphezulu
Ukucutshungulwa kwe-granite kudinga amathuluzi omshini okhethekile (njengomshini wokudweba amatshe we-CNC) namathuluzi wedayimane, futhi isivinini sokucubungula sihamba kancane, okuholela ezindleko eziphakeme zokwenza ngokwezifiso izakhiwo eziyinkimbinkimbi (njengezimbobo ezinezintambo, ama-grooves akhethekile) kanye nomjikelezo omude wokulethwa.
4. Ukushintsha okungazelelwe kwezinga lokushisa kungase kubangele ama-microcracks
Nakuba i-granite inokuzinza okuhle kokushisa, uma ihlangabezana nezinguquko ezishisayo kakhulu (njengokusuka ngokushesha endaweni yokushisa ephansi kuya endaweni yokushisa ephezulu), imifantu emincane yokucindezeleka ingase yenzeke ngaphakathi, futhi ukuqoqwa kwesikhathi eside kungase kuthinte amandla esakhiwo. Ngakho-ke, kufanele isetshenziswe ngokuqapha ezindaweni ezinomehluko omkhulu wokushisa.
5. Ayikho i-welding noma i-secondary processing
Isisekelo sensimbi singashintshwa nge-welding noma ngomshini, kodwa uma i-granite yakhiwe, cishe akunakwenzeka ukwenza izinguquko zesakhiwo (njengokubhoboza, ukusika), ngakho-ke isiteji sokuklama kufanele sihlelwe ngokunembile ukugwema ukuguqulwa kamuva.
