Amaqonga okuchaneka kwegranite asetyenziswa kakhulu kumashishini afuna ukuchaneka okuphezulu kunye nozinzo, njenge-metrology kunye nemveliso. Ngenxa yendima yawo ebalulekileyo ekugcineni ukuchaneka kobukhulu, umbuzo omnye ophambili uhlala uphakama: igranite i-hygroscopic kangakanani, kwaye ingaba inokonakala na kwindawo efumileyo? Ukuqonda iipropati zegranite ezi-hygroscopic kubalulekile ukuqinisekisa ukuba la maqonga agcina uzinzo kunye nokusebenza kwawo kwiimeko ezahlukeneyo zokusebenza.
I-granite, njengelitye lendalo, yenziwe ngeeminerali ezahlukeneyo, kuquka i-quartz, i-feldspar, kunye ne-mica. Ngokungafaniyo nezinto ezifana nomthi okanye iintsimbi ezithile, i-granite ayina-hygroscopicity iphezulu kakhulu. Oku kuthetha ukuba ayifunxi ubuninzi bomswakama kwindawo engqongileyo, nokuba kwiimeko ezifumileyo. Ulwakhiwo lwe-molecular ye-granite, oluqulunqwe kakhulu ziingqolowa zeminerali ezizinzileyo, luyenza imelane nokudumba okanye ukugoba okubangelwa kukufunxwa komswakama kwezinye izinto.
Ukungabikho kokufunxwa komswakama okukhulu yenye yezizathu zokuba i-granite ibe yinto ekhethwayo kumaqonga achanekileyo. Ngokungafaniyo nezinye izinto ezinokwanda okanye zinciphe ngenxa yotshintsho lomswakama, i-hygroscopicity ephantsi ye-granite iqinisekisa ukuba ihlala izinzile ngokwemilinganiselo nakwiindawo ezinamazinga okufuma atshintshatshintshayo. Olu phawu lubaluleke kakhulu kwizicelo ezifuna ukuchaneka okuphezulu, apho notshintsho oluncinci lwemilinganiselo lunokubangela iimpazamo kwimilinganiselo.
Nangona igranite ingafunxi umswakama kakhulu, umswakama ogqithisileyo usenokuchaphazela umphezulu wayo. Ukuba ivezwa kumanqanaba aphezulu omswakama ixesha elide, umphezulu wegranite unokuqokelelana umswakama othile womphezulu, kodwa oku ngokubanzi akwanelanga ukubangela ukuguquka okanye ukulahleka kokuchaneka. Enyanisweni, xa iphathwa kakuhle kwaye ivalwe, amaqonga egranite ayakwazi ukumelana kakhulu nezinto ezingqongileyo ezifana nomswakama, ukutshintsha kobushushu, kunye nokuvezwa ziikhemikhali.
Kubalulekile ukuqaphela, nangona kunjalo, ukuba ukugcinwa ngokufanelekileyo kubalulekile ukugcina amaqonga egranite ekwimeko efanelekileyo. Nangona ukumelana kwegranite nokufunxwa komswakama kuyinzuzo enkulu, kusacetyiswa ukuba la maqonga agcinwe kwiindawo apho umswakama ulawulwa khona. Kwiindawo ezinomswakama ophezulu kakhulu, ukuqinisekisa ukuba iqonga ligcinwa kwigumbi elilawulwa yimozulu elinamazinga obushushu kunye nomswakama ahambelanayo kuya kuthintela naziphi na izinto zangaphandle ekuchaphazeleni ukusebenza kwalo.
Ukuqukumbela, amaqonga okuchaneka kwegranite awayi-hygroscopic ngokwendlela yendabuko, kwaye ukukwazi kwawo ukumelana nokufuma okuphezulu ngaphandle kokuguquka kuwenza afaneleke ukusetyenziswa ngokuchanekileyo. Ukufunxwa kwawo kokufuma okuncinci kuqinisekisa ukuba agcina ukuchaneka kwawo kunye nozinzo, nokuba kwiindawo ezifumileyo. Nangona kunjalo, ukuqinisekisa ukusebenza ixesha elide, kusacetyiswa ukugcina nokusebenzisa la maqonga kwiindawo apho ubushushu kunye nokufuma kulawulwa khona. Ngokuqonda iimpawu zegranite kunye nokuthatha amanyathelo afanelekileyo okhuseleko, amashishini anokusebenzisa ngokupheleleyo amandla kunye nozinzo lwezixhobo kwimisebenzi echanekileyo.
