Kwicandelo lokwenziwa kwebhodi yesekethe eprintiweyo eguquguqukayo (i-FPC), izixhobo zokusika nge-laser sisixhobo esibalulekileyo sokufezekisa ukucutshungulwa kakuhle, kwaye iqonga le-granite, njengesiseko salo, lidlala indima engenakutshintshwa.
Uzinzo olubalaseleyo lobushushu
Ngexesha lenkqubo yokusika i-laser ye-FPC, ijenereyitha ye-laser ivelisa ubushushu obuninzi, kwaye kwangaxeshanye, ukusebenza kwexesha elide kwezixhobo kuya kubangela ukuba ubushushu bunyuke. I-Granite inomlinganiselo ophantsi kakhulu wokwandiswa kobushushu, idla ngokuba yi-(4-8) ×10⁻⁶/℃ kuphela. Oku kuthetha ukuba nakwindawo yokusebenza enokuguquguquka okukhulu kobushushu, utshintsho lobukhulu beqonga le-granite luncinci kakhulu. Xa kuthelekiswa nezinye izinto, umzekelo, iintsimbi zifumana ukutshintsha okukhulu kobukhulu xa ubushushu butshintsha, okunokuchaphazela ukuchaneka kwendawo phakathi kwentloko yokusika kunye nephepha le-FPC. Iqonga le-granite linokuhlala lizinzile, libonelela ngereferensi echanekileyo yokubeka intloko yokusika, liqinisekisa ukuba ukuchaneka kokusika kuhlala kwinqanaba eliphezulu ngalo lonke ixesha, liphepha ukuphambuka kokusika okubangelwa kukuguquguquka kobushushu, kwaye liqinisekisa ukuchaneka kobukhulu kunye nokuthembeka komgca weemveliso ze-FPC.
Ukusebenza okunamandla okulwa nokungcangcazela
Ngexesha lokusika nge-laser, intshukumo ekhawulezayo yentloko yokusika kunye nefuthe lee-laser pulses zombini zinokubangela ukungcangcazela. Ukongeza, ukusebenza kwezinye izixhobo kwindawo yokusebenzela yefektri kunokubangela ukuphazamiseka kokungcangcazela kokusingqongileyo. Ulwakhiwo lwangaphakathi lwe-granite luxinene, kwaye amasuntswana ekristale adibene ngokusondeleyo. Ineempawu ezintle zokudambisa kwaye inokufunxa ngempumelelo kwaye idibanise ukungcangcazela. Izifundo zibonisa ukuba amaqonga e-granite anokunciphisa i-amplitude yokungcangcazela ngaphezulu kwe-90% kwixesha elifutshane. Olu sebenzi lubalaseleyo lokulwa nokungcangcazela lunokuthintela ukungcangcazela ekudluliselweni kwintloko yokusika, kuthintelwe iingxaki ezifana nemigca engalinganiyo kunye ne-burrs emaphethelweni abangelwa kukungcangcazela ngexesha lenkqubo yokusika, ukuqinisekisa ukuguda kunye nokuqina kwemigca yokusika, kunye nokuphucula umgangatho weemveliso ze-FPC.
Ukuqina okuphezulu kunye nokumelana nokuguguleka
Ngexesha lokusebenza kwexesha elide kwezixhobo zokusika nge-laser ze-FPC, intloko yokusika ihamba rhoqo, nto leyo ebeka iimfuno eziphezulu kakhulu kumandla okuthwala umthwalo kunye nokumelana nokuguguleka kwesiseko. I-Granite inobunzima obuphezulu, enobunzima be-Mohs obuyi-6 ukuya kwi-7, kwaye inokumelana okunamandla okucinezelwa kunye nokumelana nokuguguleka. Ulwakhiwo lwayo oluqinileyo lunokuxhasa ngokuzinzileyo izinto ezahlukeneyo zezixhobo zokusika. Nokuba phantsi kwemisebenzi yokusika ephindaphindayo, ayiguguleki okanye iguguleke. Xa kuthelekiswa nezinye izinto ezisisiseko ezigugulekayo, amaqonga e-granite anciphisa kakhulu ingxaki yokwehla kokuchaneka okubangelwa kukuguguleka, andise ubomi benkonzo iyonke yezixhobo, kwaye anciphise iindleko zokugcina kunye nokutshintsha izixhobo.
Uzinzo oluhle lweekhemikhali
Kusenokubakho ezinye izinto zeekhemikhali kwindawo yokuvelisa i-FPC, ezifana nezicoci kunye neefluxes. I-Granite yenziwe kakhulu ziiminerali ezifana ne-quartz kunye ne-feldspar. Ineempawu zeekhemikhali ezizinzileyo kunye nokumelana okuhle kokugqwala, kwaye imelana kakhulu nezinto zeekhemikhali ezifana nee-asidi kunye ne-alkalis. Oku kuqinisekisa ukuba iqonga le-granite aliyi konakala kukukhukuliseka kweekhemikhali kwiindawo zemveliso ezinzima, okuqinisekisa uzinzo kunye nokuthembeka kwexesha elide kwesiseko kunye nokubonelela ngesiqinisekiso sokusebenza okuqhubekayo nokuzinzileyo kwezixhobo zokusika i-laser ze-FPC.
Izixhobo zokusika nge-laser ze-FPC zikhetha iqonga le-granite njengesiseko ngenxa yokusebenza kwalo okugqwesileyo kwiinkalo ezininzi ezifana nokuzinza kobushushu, ukumelana nokungcangcazela, ukuqina kunye nokumelana nokuguguleka, kunye nokuzinza kweekhemikhali. Ezi mpawu zisebenza kunye ukuphucula ukuchaneka kokusika kunye nomgangatho wemveliso, ukwandisa ubomi benkonzo yezixhobo, ukunciphisa iindleko zizonke, kunye nokukhuthaza ngempumelelo uphuhliso olusemgangathweni ophezulu lweshishini lokuvelisa le-FPC.
