Uphuculo olutsha kuququ zokuqinisekiswa komgangatho wepavuli yekhonkrithi inokubonelela ngolwazi olubalulekileyo malunga nomgangatho, ukuqina, kunye nokuthotyelwa kweekhowudi zoyilo lwe-hybrid.
Ulwakhiwo lwendlela yekhonkrithi lunokubona imeko kaxakeka, kwaye ikhontraktha kufuneka iqinisekise umgangatho kunye nokuqina kwekhonkrithi yekhonkrithi. Ezi ziganeko ziquka ukuvezwa kwemvula ngexesha lokuqalisa, ukusetyenziswa kweposti yokuphilisa, iplastiki yeplastiki kunye nokukrazula iiyure kwiiyure ezimbalwa emva kokuthulula ngokulandelelana, kunye nemiba eguqulwayo. Nokuba izinto ezifunekayo amandla kunye nolunye uvavanyo lwezinto ezibonakalayo ziyafezekiswa, iinjineli zinokufuna ukususwa kunye nokutshintshwa kwamalungu eendlela kuba zinexhala lokuba i-ITIVE YENKONZO YENKCAZO YOKUTHENGA INDAWO YOKUZIPHATHA.
Kule meko, iindlela zepetrografi kunye nezinye iindlela zokuvavanya iindlela zovavanyo zinokubonelela ngolwazi olubalulekileyo malunga nomgangatho kunye nokuqina komxube wekhonkrithi nokuba bayadibana nale ngcaciso yomsebenzi.
Umzobo woku-1 Inani lasekhohlo lasekhohlo libonisa isixhobo sokulinganisa ukumelana nokuyekiswa kwekhonkrithi yekhonkrithi. Umzobo ongezantsi ongezantsi ubonakalisa ubudlelwane phakathi kokunganyangwa kwe-app I-chunyu qiao kunye ne-drp, inkampani ethatyathiweyo
Umthetho ka-Abram:
Unjingalwazi Duff Abrams kuqala wachaza ubudlelwane phakathi kwenqanaba lesamente kwamanzi (i-W / C) kunye ne-1] [1] [1] [1] [1] [1], kwaye yaqulunqa umlinganiselo ocacileyo wamanzi / weqhinga. " Ukongeza ekulawuleni amandla oxinzelelo, iradi yamanzi (i-W / CM) ithandwa ngenxa yokuba ifanelekile ukutshintshwa kwesamente yasePortland ngezixhobo zokuncedisa ezifana ne-stanment ash kunye ne-slag. Ikwayiphamela ephambili yokuqina kwekhonkrithi. Izifundo ezininzi zibonakalise ukuba umxube wekhonkrithi one-W / cm ezantsi kune ~ 0.45 ziyahlala ziqinile kwiindawo ezinomsindo, ezinje ngeendawo ezinomtsalane ze-subts okanye iindawo ezinokugxila kuzo emhlabeni.
I-capillary pores yinxalenye yendalo yesamente. Ziqulathe indawo phakathi kweemveliso ze-qumences shydration kunye nezilonda ezingenamsebenzi ezazizele ngamanzi. . Xa i-capillary ixhunyiwe, ulwelo olusuka kwimo yangaphandle lunokufudukela kwi-paste. Le phenonon ibizwa ngokuba yingeneyo kwaye kufuneka incitshiswe ukuqinisekisa ukuqina. ULULUMKISO WOKUGQIBELA WOKUGQIBELA WOKUGQIBELA UKUZE I-POSS iqhekekile kunokuba iqhagamshelwe. Oku kuyenzeka xa i-w / cm ingaphantsi kwe ~ 0.45.
Nangona kunzima ukulinganisa ngokuchanekileyo i-W / CM yekhonkrithi ebi, indlela ethembekileyo inokubonelela ngesixhobo esibalulekileyo sokuqinisekisa ukuba kuphando lwe-proed-ndawoct yekhonkrithi. Imicroscopy i-microscopy ibonelela ngesisombululo. Yile ndlela isebenza ngayo.
I-Fluorescence microscopy yindlela esebenzisa i-epoxy resin kunye ne-fluorescent dy yokukhanyisa iinkcukacha. Ihlala isetyenziswa kwiiSayensi zoNyango, kwaye ikwanazo nezicelo ezibalulekileyo kwiSayensi yeZandla. Ukusetyenziswa kwenkqubo yale ndlela kwikhonkrithi yaqala phantse kwiminyaka engama-40 eyadlulayo eDenmark [3]; Kwakubekwe emgangathweni kumazwe acocekileyo ngo-1991 ngokuqikelela i-W / C yekhonkrithi, kwaye yahlaziywa ngo-1999 [4].
Ukulinganisa i-W / cm yezinto ezisekwe kwisamente (okt ikhonkrithi, udaka, kunye ne-Inseorescent), ibhloko yekhonkrithi isetyenziselwa i-microns ezimalunga ne-25 microns (umzobo 2). Inkqubo ibandakanya ikhonkrithi okanye i-cylinder inqunyulwe kwiibhloko zekhonkrithi zekhonkrithi (ezibizwa ngokuba yi-Blanks) kunye nendawo emalunga ne-25 x 50 mm (1 x 2 i-intshi). I-fan ifakwe kwilayisi yeglasi, ibekwe kwigumbi lokuphumla, kwaye i-epoxy resin yaziswa phantsi kwe-vacuum. Njengoko i-W / CM inyuswa, unxibelelwano kunye nenani le-pores liya kunyuka, ukuze i-epoxy ngakumbi iya kungena kwi-paste. Sijonga ii-flakes phantsi kwe-microscope, usebenzisa iseti yeefiltha ezikhethekileyo ukuze zivuselele i-fluorescent dys kwi-epoxy resin kwaye ihluze imiqondiso engaphezulu. Kule mifanekiso, iindawo ezimnyama zimele amasuntswana ahlanganisayo kunye namasuntswana angenamva. I-peresity yezibini i-0%. Isangqa esilileyo esiluhlaza sisimo sengqondo (hayi ukuthambeka), kwaye i-peresity i-100%. Enye yezi zinto zinoluhlobo olukhoyo "lwento" yincamathisi (umzobo 2). Njengoko i-W / CM kunye ne-capillary i-carosity yonyuselo lwekhonkrithi, umbala oluhlaza ohlukileyo we-paste uba luqaqambile kwaye iqaqambe (jonga umfanekiso 3).
Umfanekiso 2 Ububanzi bentsimi ethe tye yi-1.5 mm. I-chunyu qiao kunye ne-drp, inkampani ethatyathiweyo
Umzobo 3. I-Fluoresces micrografis yeflethi ibonisa ukuba njengoko i-W / CM inyuswe, i-payishini eluhlaza ngokuthe ngcembe iqaqambe. Le mixube inyibilikisiwe kwaye iqulethe i-ash yempukane. I-chunyu qiao kunye ne-drp, inkampani ethatyathiweyo
Uhlalutyo lwemifanekiso lubandakanya ukuqalisa idatha yobungakanani kwimifanekiso. Isetyenziswa kwimimandla emininzi eyahlukileyo yesayensi, kwii-microscope ezikude. I-pixel nganye kumfanekiso wedijithali iba yindawo yedatha. Le ndlela isivumela ukuba sichithise amanani kumanqanaba ahlukeneyo aluhlaza abonakale kule mifanekiso. Kule minyaka ingama-20 idlulileyo okanye ngaphezulu, kunye nenguqu kwikhompyuter yamandla ekhompyuter kunye nokufunyanwa komfanekiso wedijithali, uhlalutyo lwemifanekiso ngoku luba sisixhobo esisebenzayo esinokusetyenziswa. Sisoloko sisebenzisa uhlalutyo lwemifanekiso ukulinganisa i-capillary ye-capillary ye-slirry. Ixesha elingaphelanga, safumanisa ukuba kukho unxibelelwano oluqinileyo lwenkcukacha-manani phakathi kwe-W / CM kunye ne-careillary i-caresity, njengoko kubonisiwe kweli nani (umzobo 4 kunye nomzobo 5)).
Umzobo 4. Umzekelo wedatha efunyenwe kwii-fluoresces ezincinci zamacandelo anqabileyo. Le grafu iceke inani leephikseli kwinqanaba elingwevu elingwevu kwifoto enye. Iincopho ezintathu zihambelana ne-agergates (i-orange curve), uncamathisela (i-Grey Indawo), kwaye i-void (i-Peaki engabhaliswanga ngasekunene). Ijikajika le-paste ivumela umntu ukuba abale ubungakanani be-pore ophakathi kunye nokuphambuka komgangatho. I-Chunji Qiao kunye ne-DRP, iNkampani yeNkampani ye-5. Le grafu ishwankathela uthotho lwe-W / CM ePhakathiweyo kwimixube equlunqwa yesamente equlunqeweyo, kunye ne-pozdolan yendalo. I-chunyu qiao kunye ne-drp, inkampani ethatyathiweyo
Kuhlalutyo lokugqibela, iimvavanyo ezintathu ezizimeleyo ziyafuneka ukubonisa ukuba ikhonkrithi eseleyo ihambelana nenkcazo yoyilo yomxube. Kangangoko kunokwenzeka, fumana isampulu ephambili ekubekweni edibana nayo yonke imigaqo yokwamkela, kunye neesampulu ezivela kwiindawo ezinxulumene noko. Isiseko esivela kumda owamkelweyo sinokusetyenziswa njengesampulu yolawulo, kwaye ungayisebenzisa njengophawu lokuvavanya ukuthotyelwa kwesakhiwo esifanelekileyo.
Kumava ethu, xa iinjineli ezineenjineli ziyayibona idatha efunyenwe kwezi mvavanyo, zihlala zamkela ukufakwa ukuba ezinye iimpawu zobunjineli zezobunjineli (njengamandla ecinezelweyo) ziyafezekiswa. Ngokubonelela ngemilinganiselo yobungakanani be-W / cm kunye nento yokwenza, sinokudlula ngaphaya kweemvavanyo ezichazwe kwimisebenzi emininzi yokungqina ukuba imixube yombuzo inemigangatho efanelekileyo.
UDavid Rothstein, ph.d., Pg, fit fit yindawo eyiNtloko yeLithografi ye-DRP, inkampani enamasi. Uneminyaka engaphezu kwama-25 yamava epetrologistrist kwaye ahlolwe ngokwakhe iisampulu ezingaphezulu kwe-10,000 ukusuka kwiiprojekthi ezingaphezu kwe-2 000 kwihlabathi liphela. UGqirha Chunji qiiao, intloko yenzululwazi ye-DRP, inkampani enamaweyo, i-geologist kunye nezixhobo zenzululwazi ngeminyaka elishumi kunye neemveliso zelitye zendalo nezendalo nezendalo nezendalo nezendalo nezendalo nabazinzileyo. Ingcali yakhe ibandakanya ukusetyenziswa kohlalutyo lwemifanekiso kunye ne-fluorescence microscopy yokufunda isimo sekhonkrithi, ngokugxininiswa okukhethekileyo kumonakalo obangelwe ziityuwa, ukuhlaselwa kwemichiza, kunye nokuhlaselwa kwemichiza kwizityalo zonyango lwamanzi amdaka.
