Kwihlabathi le-ultra-precision metrology, isixhobo sokulinganisa i-granite ayisosithinteli esinzima samatye; ngumgangatho osisiseko ekugwetywa ngawo yonke eminye imilinganiselo. Ukuchaneka kokugqibela komgangatho-okuphunyeziweyo kuluhlu lwe-micron kunye ne-sub-micron-iqala ixesha elide ngaphambi kwenkqubo yokugqibela, enobuchule bokuqhawula. Kodwa ziziphi iinkqubo zokuqala ngokwenene ezamisela isiseko sokuchaneka okungenakuthelekiswa nanto? Iqala ngamanqanaba amabini abalulekileyo, asisiseko: ukhetho olungqongqo lwemathiriyeli yegranite eluhlaza kunye nenkqubo yokusika echanekileyo esetyenziselwa ukuyibumba.
UbuGcisa kunye neNzululwazi yoKhetho lweMathiriyeli
Ayiyiyo yonke igranite eyenziwe yalingana, ngakumbi xa imveliso kufuneka isebenze njengesizinzileyo, isixhobo sokulinganisa ireferensi njengepleyiti yomphezulu, isikweri-ntathu, okanye umphetho othe ngqo. Inkqubo yokhetho yenzululwazi enzulu, igxile kwiimpawu zendalo eziqinisekisa uzinzo kumashumi eminyaka.
Sifuna ngokukodwa iintlobo zegranite ezimnyama ezixinana kakhulu. Umbala ubonisa ukuxinwa okuphezulu kweeminerali ezixineneyo, ezimnyama, ezifana ne-hornblende, kunye nesakhiwo esincinci sengqolowa. Olu lwakhiwo alunakuxoxisana ngomsebenzi ochanekileyo ngenxa yezizathu ezininzi eziphambili. Okokuqala, i-Low Porosity kunye ne-High Density yeyona nto ibalulekileyo: isakhiwo esiqinileyo, esicacileyo sinciphisa i-voids yangaphakathi kwaye yandisa ukuxinana, okuguqulela ngokuthe ngqo kwiimpawu eziphezulu zokudambisa ngaphakathi. Lo mthamo uphezulu wokumanzisa ubalulekile ekubambeni ngokukhawuleza ukungcangcazela komatshini, ukuqinisekisa ukuba indawo yokulinganisa ihlala izinzile. Okwesibini, izinto eziphathekayo kufuneka zibonise i-Coefficient ephantsi kakhulu yoKwandiswa kweThermal (COE). Le propati ibalulekile, njengoko inciphisa ukwandiswa okanye ukucutheka ngokuguquguquka okuqhelekileyo kobushushu kwindawo yolawulo lomgangatho, iqinisekisa isixhobo sigcina ingqibelelo yaso enomda. Okokugqibela, igranite ekhethiweyo kufuneka ibe namandla acinezelayo aphezulu kunye noSasazo lweMineral olufanayo. Oku kufana kuqinisekisa ukuba imathiriyeli iphendula ngokuqikelelwa kwangaphambili ngexesha lokusikwa okulandelayo kwaye, okona kubaluleke kakhulu, inqanaba elibalulekileyo lokuqengqeleka ngesandla, lisivumela ukuba sifezekise kwaye sibambe unyamezelo lwethu olufunayo.
Inkqubo yokusika echanekileyo
Emva kokuba ibhloko ecocekileyo efanelekileyo ikhutshwe kwi-quarry, isigaba sokuqala sokubumba-ukusika-yinkqubo yoshishino eyinkimbinkimbi eyenzelwe ukunciphisa uxinzelelo lwempahla kunye nokubeka isiteji sokugqiba i-ultra-precision. Iindlela eziqhelekileyo zokusika i-masonry akwanelanga; ukuchaneka kwegranite kufuna izixhobo ezikhethekileyo.
Ubuchwephesha bemeko yangoku yokusika ibhloko enkulu yegranite yiDiamond Wire Saw. Le ndlela ithatha indawo yee-blades zesetyhula zendabuko kunye ne-loop eqhubekayo yentambo yensimbi ephezulu efakwe kwiidayimani zoshishino. Ukusetyenziswa kwale ndlela kunika iingenelo ezicacileyo: kuqinisekisa ukuNcitshiswa koxinzelelo kunye nokushisa ngenxa yokuba i-diamond wire saw isebenza ngokuqhubekayo, i-multi-directional motion, ehambisa imikhosi yokusika ngokulinganayo kuyo yonke into. Oku kunciphisa umngcipheko wokuzisa uxinzelelo olushiyekileyo okanye i-micro-cracks kwi-granite-ingozi eqhelekileyo kunye ne-single-pass, iindlela zokusika iimpembelelo eziphezulu. Okubaluleke kakhulu, inkqubo iqhele ukuba manzi, isebenzisa umjelo othe rhoqo wamanzi ukupholisa ucingo kunye nokugungxula uthuli lwegranite, ngaloo ndlela kuthintelwa umonakalo owenziwe wasekhaya onokubeka esichengeni uzinzo lwexesha elide lwemathiriyeli. Obu buchule buvumela ngakumbi ukuSebenza kunye neSikali, okwenza ukubunjwa okuchanekileyo kweebhloko ezinkulu-ezifunekayo kwiipleyiti zegranite eziphezulu zefomati enkulu okanye iziseko zomatshini-kunye nolawulo olungazange lubonwe ngaphambili, ukubonelela ngejiyometri echanekileyo yokuqala enciphisa kakhulu ixesha kunye nenkunkuma yezinto eziphathekayo ezibandakanyekayo kwizigaba ezilandelayo zokusila.
Ngokujolisa ngokungayekiyo ekukhethweni kwezona zinto zixineneyo, zizinzile kunye nokuphunyezwa kweendlela eziphambili, zokunciphisa uxinzelelo, siqinisekisa ukuba isixhobo ngasinye sokulinganisa i-granite ye-ZHHIMG senziwa ngomgangatho wendalo ofunekayo kowona mlinganiselo wehlabathi uchanekileyo. Ukugqithela ngobuchule okulandelayo sisenzo sokugqibela kuphela kwinkqubo yemveliso eyenziwe ngobunono.
