Phantsi kweemeko eziqhelekileyo, uxinano lwegranite alutshintshi kakhulu ngokuhamba kwexesha, kodwa phantsi kweemeko ezithile ezithile, lunokutshintsha. Oku kulandelayo luhlalutyo oluvela kwiinkalo ezahlukeneyo:
Phantsi kweemeko eziqhelekileyo, uxinano luzinzile
I-Granite lilitye eliyi-igneous elenziwe ziiminerali ezifana ne-feldspar, i-quartz kunye ne-mica, kwaye inkqubo yokwakheka kwayo inde kwaye iyinkimbinkimbi. Emva kokwakheka kwayo, ulwakhiwo lwayo lwangaphakathi lweeminerali kunye nokwakheka kweekhemikhali kuzinzile. I-Granite inesakhiwo esixineneyo esinamasuntswana afanayo nancinci. I-porosity yayo ngokubanzi yi-0.3% - 0.7%, kwaye izinga layo lokufunxwa kwamanzi lidla ngokuba phakathi kwe-0.15% kunye ne-0.46%. Logama nje ingachaphazeleki ziziphumo ezinamandla zomzimba nezekhemikhali ezivela ngaphandle, ulungiselelo lweeminerali ngaphakathi aluyi kutshintsha lula, kwaye ubunzima ngeyunithi nganye buya kuhlala buhleli, kunye noxinano oluzinzileyo ngokwendalo. Umzekelo, izinto zegranite ezisetyenziswa kwezinye izakhiwo zakudala ziye zahlala amakhulu okanye amawaka eminyaka. Kwimeko egcinwe kakuhle, uxinano lwazo aluzange lutshintshe nantoni na ebonakalayo.
Iimeko ezikhethekileyo zinokubangela utshintsho kuxinano
Isiphumo somzimba: Ukuba i-granite iphantsi kwamandla angaphandle abalulekileyo afana nokucinezelwa kunye nempembelelo ixesha elide, inokubangela utshintsho oluncinci kwisakhiwo sayo sangaphakathi. Umzekelo, kwiindawo ezineenyikima ezixhaphakileyo, i-granite iphantsi koxinzelelo olunamandla olubangelwa kukuhamba kwe-crustal. Izikhewu phakathi kwamasuntswana eeminerali zangaphakathi zinokucinezelwa kwaye zincitshiswe, kwaye ii-pores ezincinci ezazikho ekuqaleni zinokuvalwa kancinci, nto leyo ebangela ukwanda kobunzima bezinto ngeyunithi nganye kunye nokunyuka koxinano. Nangona kunjalo, olo tshintsho luhlala luncinci kakhulu kwaye lufuna amandla angaphandle anamandla kakhulu kwaye aqhubekayo ukuze kwenzeke.
Impendulo yekhemikhali: Xa igranite ivezwa kwindawo ekhethekileyo yeekhemikhali ixesha elide, uxinano lwayo lunokutshintsha. Umzekelo, ukuba igranite ivezwa kwizinto ezineasidi okanye i-alkaline ixesha elide, ezinye zezixhobo zayo zezimbiwa zinokusabela kwiikhemikhali zezi khemikhali. Iiminerali ezifana ne-feldspar kunye ne-mica zinokubola kwaye zinyibilike kwiindawo ezineasidi, nto leyo ekhokelela ekulahlekelweni kwezinye izinto. Oku kubangela ukuba kubekho imingxuma emininzi ngaphakathi kwegranite, ukuncipha kobunzima ngokubanzi, ngaloo ndlela ukwehla koxinano. Ukongeza, xa igranite ivezwa kwindawo emanzi enomthamo omkhulu wekhabhoni diokside ixesha elide, inokujamelana neempendulo zekhabhoni, nto leyo eya kuchaphazela nolwakhiwo lwangaphakathi kunye nokwakheka kwayo, kwaye ngaloo ndlela ichaphazele uxinano lwayo.
Ukuhla kwemozulu: Phantsi kweziphumo zemozulu zexesha elide ezifana nomoya, ukuvezwa lilanga kunye nemvula, umphezulu wegranite uya kuqhekeka kancinci kancinci kwaye ubole. Nangona ukuhla kwemozulu kuchaphazela kakhulu umaleko womphezulu wegranite, njengoko ixesha lihamba kwaye ukuhla kwemozulu kusiba nzulu, izinto zegranite ziya kulahleka. Phantsi kwemeko yokuba umthamo awutshintshi okanye utshintsha kancinci, ubunzima buya kuncipha kwaye uxinano nalo luya kuncipha. Nangona kunjalo, ukuhla kwemozulu yinkqubo ecothayo kakhulu kwaye kungathatha amakhulu okanye amawaka eminyaka ukuba uxinano lutshintshe kakhulu.
Lilonke, phantsi kweemeko eziqhelekileyo zokusingqongileyo nokusetyenziswa, uxinano lwegranite lunokuthathwa njengoluzinzileyo nolungatshintshanga. Nangona kunjalo, phantsi kwempembelelo yeendawo ezikhethekileyo zomzimba, iikhemikhali kunye nezendalo, uxinano lwayo lunokutshintsha ukuya kwinqanaba elithile ngokuhamba kwexesha.
