Kwimizi-mveliso echanekileyo, i-aerospace, kunye ne-metrology, ukusebenza kwezixhobo zoomatshini ezisisiseko (umz., iitafile zomsebenzi zoomatshini, iziseko, kunye neereyile zesikhokelo) kuchaphazela ngokuthe ngqo ukuchaneka kwezixhobo kunye nokuzinza kokusebenza. Izixhobo zegranite kunye nezixhobo zemabula zombini zihlelwa njengezixhobo zendalo zokuchaneka kwelitye, kodwa izixhobo zegranite zihlukile ngokuqina kwazo okuphezulu kunye nokuqina kwazo—okuzenza zibe lolona khetho lukhethwayo kwizicelo zoshishino ezithwala umthwalo ophezulu, ezihlala ixesha elide. Njengomthengisi ophambili kwihlabathi liphela wezixhobo zelitye ezichanekileyo, i-ZHHIMG izimisele ukucacisa iipropati zezinto kunye neenzuzo eziphambili zezixhobo zegranite, ikuncede ukhethe isisombululo esifanelekileyo sesiseko sezixhobo zakho zokuchaneka.
1. Yintoni Izinto Ezisetyenziswa Kwizinto ZeGranite?
Izinto zegranite zenziwe ngegranite yendalo ekumgangatho ophezulu—uhlobo lwelitye eliyi-igneous elenziwe kukuphola kancinci kunye nokuqina kwe-magma engaphantsi komhlaba. Ngokungafaniyo nemarble eqhelekileyo, ukukhethwa kwezinto eziluhlaza zezinto zegranite kulandela imigangatho engqongqo yemizi-mveliso ukuqinisekisa ukusebenza koomatshini kunye nokugcinwa ngokuchanekileyo:
1.1 Iimfuno zeZixhobo eziPhambili
- Ubunzima: Kufuneka bufikelele kubunzima beShore (Hs) obungama-70 nangaphezulu (obulingana nobunzima beMohs obuyi-6-7). Oku kuqinisekisa ukumelana nokuguguleka kunye nokuguquka phantsi koxinzelelo loomatshini oluhlala ixesha elide—oludlula kakhulu ubunzima bentsimbi ephosiweyo (Hs 40-50) okanye imabula eqhelekileyo (Hs 30-40).
- Ukufana kwesakhiwo: I-granite kufuneka ibe nesakhiwo seeminerali esixineneyo nesifanayo esingenazimfanta zangaphakathi, iimbobo, okanye izinto ezifakwe kwiiminerali ezinkulu kune-0.5mm. Oku kuthintela uxinzelelo lwendawo ngexesha lokucubungula okanye ukusebenzisa, okunokukhokelela ekulahlekelweni kokuchaneka.
- Ukuguga Ngokwendalo: I-granite eluhlaza idlula ubuncinane iminyaka emi-5 yokuguga ngokwendalo ngaphambi kokuba isetyenzwe. Le nkqubo ikhulula ngokupheleleyo uxinzelelo lwangaphakathi olushiyekileyo, iqinisekisa ukuba icandelo eligqityiweyo aliguquguquki ngenxa yotshintsho lobushushu okanye ukufuma kokusingqongileyo.
1.2 Itekhnoloji yoLungiselelo
Izinto zegranite zeZHHIMG zenziwe ngenkqubo enzima, enamanyathelo amaninzi ukuhlangabezana neemfuno zokuchaneka ngokwezifiso:
- Ukusikwa Ngokwesiko: Iibhloko zegranite eziluhlaza zisikwa zibe ziindawo ezingenanto ngokwemizobo ye-2D/3D ebonelelwe ngumthengi (exhasa izakhiwo ezintsonkothileyo ezifana nemingxunya, iindawo ezivulekileyo, kunye nemikhono yentsimbi efakwe ngaphakathi).
- Ukusila ngokuchanekileyo: Oomatshini bokusila be-CNC (abachanekileyo be-±0.001mm) basetyenziselwa ukucokisa umphezulu, nto leyo eyenza ukuba kubekho impazamo yokuba tyaba ye-≤0.003mm/m kwiindawo eziphambili.
- Ukubhola kunye nokugqobhoza: Izixhobo zedayimani ezichanekileyo kakhulu zisetyenziselwa ukubhola (ukuchaneka kwendawo yomngxuma ±0.01mm) kunye nokugqobhoza, ukuqinisekisa ukuhambelana nezixhobo zoomatshini (umz., iireyili zesikhokelo, iibholiti).
- Unyango Lomphezulu: Kusetyenziswa isitywina esingenatyhefu, esikumgangatho wokutya ukunciphisa ukufunxwa kwamanzi (ukuya kuthi ga kwi-≤0.15%) kunye nokuphucula ukumelana nokugqwala—ngaphandle kokuchaphazela iimpawu ezingezizo zemagnethi zecandelo.
2. Iimpawu eziphambili zeGranite Components: Kutheni Zisebenza Kakuhle Kakhulu Kwizinto Zemveli
Izixhobo zegranite zibonelela ngeenzuzo ezikhethekileyo ngaphezu kwesinyithi (isinyithi esityhidiweyo, isinyithi) okanye izinto zokwenziwa, nto leyo eyenza ukuba zibe yimfuneko kwiinkqubo zoomatshini ezichanekileyo:
2.1 Ukuchaneka Okumangalisayo kunye Nozinzo
- Ukugcinwa Ngokuchaneka Okusisigxina: Emva kokwaluphala kwendalo kunye nokulungiswa ngokuchanekileyo, izinto zegranite azinazo iiplastiki eziguquguqukayo. Ukuchaneka kwazo ngobukhulu (umz., ukuba tyaba, ukuthe tye) kunokugcinwa iminyaka engaphezu kwe-10 phantsi kokusetyenziswa okuqhelekileyo—ukususa imfuneko yokulungiswa rhoqo.
- I-Coefficient yoKwandisa ubushushu obuphantsi: I-Granite ine-coefficient yokwandiswa okuthe ngqo eyi-5.5×10⁻⁶/℃ kuphela (1/3 yentsimbi ephosiweyo). Oku kuthetha utshintsho oluncinci kakhulu nakwiindawo zokusebenzela ezinokuguquguquka kobushushu (umz., 10-30℃), ukuqinisekisa ukusebenza okuzinzileyo kwezixhobo.
2.2 Iipropati zoomatshini eziBalaseleyo
- Ukumelana Nokuguguleka Okuphezulu: Iiminerali ze-quartz ezixineneyo kunye ne-feldspar kwi-granite zibonelela ngokumelana nokuguguleka okugqwesileyo—okuphindwe ka-5-10 kune-cast iron. Oku kubalulekile kwizinto ezifana nee-rails zesikhokelo sezixhobo zomatshini, ezinyamezela ukuguguleka okuphindaphindiweyo.
- Amandla Aphezulu Okucinezela: Ngamandla axineneyo angama-210-280MPa, izinto zegranite zinokumelana nemithwalo enzima (umz., 500kg/m² kwiitafile zokusebenza) ngaphandle kokuguqulwa—zilungele ukuxhasa oomatshini abakhulu abachanekileyo.
2.3 Iingenelo zoKhuseleko noLondolozo
- AyinaMagnetic kwaye AyinaConductive: Njengento engeyiyo yesinyithi, igranite ayivelisi magnetic fields okanye idlulise umbane. Oku kuthintela ukuphazamiseka kwezixhobo zokulinganisa imagnethi (umz., izalathisi zedayali) okanye izinto ze-elektroniki ezibuthathaka, ukuqinisekisa ukufunyanwa ngokuchanekileyo kwezixhobo zomsebenzi.
- Ayinamhlwa kwaye ayimelani nokugqwala: Ngokungafaniyo nentsimbi okanye intsimbi ephoswe ngentsimbi, igranite ayigqwali. Ikwamelana nezinyibilikisi ezininzi zoshishino (umz., ioyile yeminerali, utywala) kunye nee-acids/alkalis ezibuthathaka—inciphisa iindleko zokulungisa kwaye yandise ubomi benkonzo.
- Ukumelana Nomonakalo: Ukuba umphezulu wokusebenza ukrwelwe ngengozi okanye uchaphazeleke, wenza kuphela imingxunya emincinci, enganzulu (akukho ziqhuma okanye imiphetho ephakanyisiweyo). Oku kuthintela ukonakala kwezinto zokusebenza ezichanekileyo kwaye akuchaphazeli ukuchaneka kokulinganisa—ngokungafaniyo nemiphezulu yesinyithi, enokubangela ukuguguleka okufuna ukuphinda kugaywe.
2.4 Ukulungiswa okulula
Izixhobo zegranite zifuna ukugcinwa okuncinci:
- Ukucoca imihla ngemihla kufuna kuphela ilaphu elithambileyo elifakwe kwisepha engathathi cala (ukuphepha izicoci ze-asidi/ze-alkaline).
- Akukho mfuneko yokuthambisa ngeoyile, ukupeyinta, okanye unyango lokuthintela umhlwa—okonga ixesha kunye nomsebenzi kumaqela okulungisa ifektri.
3. Izisombululo zeGranite Component zeZHHIMG: Zenzelwe iiShishini zeHlabathi
I-ZHHIMG igxile ekuveliseni izinto zegranite ezenziwe ngokwezifiso kwiindidi ezahlukeneyo zamashishini, kuquka i-aerospace, iimoto, i-semiconductor, kunye nezixhobo ezichanekileyo. Iimveliso zethu ziquka:

- Ukuhlolwa kwezinto: Ibhetshi nganye yegranite ivavanywa ubulukhuni, uxinano, kunye nokufunxwa kwamanzi (ngesiqinisekiso se-SGS).
- Ukulinganisa ngokuchanekileyo: Ii-interferometer ze-laser zisetyenziselwa ukuqinisekisa ukuba zithe tyaba, zithe tye, kwaye ziyafana—kunye nengxelo eneenkcukacha zokulinganisa enikiweyo.
- Ukuguquguquka kokwenziwa ngokwezifiso: Inkxaso yobukhulu ukusuka kwi-500×300mm ukuya kwi-6000×3000mm, kunye nonyango olukhethekileyo olufana nemikhono yentsimbi efakwe ngaphakathi (yokudibanisa iibholiti) okanye iileya zokuthintela ukungcangcazela.
Ukongeza, sinikezela ngewaranti yeminyaka emi-2 kunye nokubonisana ngobuchwepheshe kwasimahla kuzo zonke izinto zegranite. Inethiwekhi yethu yezothutho yehlabathi iqinisekisa ukuhanjiswa ngexesha elifanelekileyo kumazwe angaphezu kwama-50, kunye nesikhokelo sokufakelwa kwindawo esifumanekayo kwiiprojekthi ezinkulu.
4. Imibuzo Ebuzwa Rhoqo: Imibuzo Eqhelekileyo Malunga Neenxalenye zeGranite
Umbuzo 1: Ngaba izinto zegranite zinzima kunezinto zesinyithi esityhidiweyo?
A1: Ewe—igranite inobunzima obuyi-2.6-2.8g/cm³ (ingaphezulu kancinci kune-7.2g/cm³ yentsimbi ephosiweyo ayichanekanga, ilungisiwe: ubunzima bentsimbi ephosiweyo yi ~7.2g/cm³, igranite yi ~2.6g/cm³). Nangona kunjalo, ukuqina okuphezulu kwegranite kuthetha ukuba uyilo oluncinci nolukhaphukhaphu lunokufikelela kuzinzo olufanayo nolweendawo ezinkulu zentsimbi ephosiweyo.
Umbuzo 2: Ngaba izinto zegranite zingasetyenziswa kwiindawo ezingaphandle okanye ezinomswakama ophezulu?
A2: Ewe—Iinxalenye zegranite zeZHHIMG ziphathwa ngendlela ekhethekileyo yokuthintela amanzi ukuba angangeni (i-surface sealant) ukunciphisa ukufunxwa kwamanzi ukuya kuthi ga kwi-≤0.15%. Zifanelekile kwiindawo zokusebenzela ezifumileyo, kodwa akukhuthazwa ukuba zibekwe ngaphandle ixesha elide (emvuleni/elangeni).
Q3: Kuthatha ixesha elingakanani ukuvelisa izinto zegranite ezenziwe ngokwezifiso?
A3: Kwiindlela ezisemgangathweni zoyilo (umz., iitafile zokusebenza eziziingxande), imveliso ithatha iiveki ezi-2-3. Kwizakhiwo ezintsonkothileyo (ezinemingxuma/izithuba ezininzi), ixesha lokuqalisa liziiveki ezi-4-6—kuquka uvavanyo lwezinto kunye nokulinganiswa ngokuchanekileyo.
