Amaqonga achanekileyo egranite asetyenziswa kakhulu kumashishini afuna ukuchaneka okuphezulu kunye nozinzo, njenge-metrology kunye nokuveliswa. Ngenxa yendima yabo ebalulekileyo ekugcineni ukuchaneka komda, omnye umbuzo ophambili uhlala uvela: ingaba i-hygroscopic yigranite njani, kwaye ingakhubaza kwindawo efumileyo? Ukuqonda iimpawu ze-hygroscopic ze-granite kubalulekile ekuqinisekiseni ukuba la maqonga agcina uzinzo kunye nokusebenza kwiimeko ezahlukeneyo zokusebenza.
I-Granite, njengelitye lendalo, yenziwe ngamaminerali ahlukeneyo, kuquka i-quartz, i-feldspar, kunye ne-mica. Ngokungafaniyo nezinto ezifana nemithi okanye iintsimbi ezithile, i-granite ine-hygroscopicity ephantsi kakhulu. Oku kuthetha ukuba ayifunxi izixa ezibalulekileyo zokufuma kwindawo eyingqongileyo, nakwiimeko zokufuma. Ulwakhiwo lwemolekyuli yegranite, eyona nto iqulethwe ziinkozo zeminerali ezizinzile, yenza ukuba ikwazi ukumelana nokudumba okanye i-warping ukuba ukufunxwa komswakama kubangela kwezinye izinto.
Ukungabikho kokufunxa okubalulekileyo kokufuma sesinye sezizathu zokuba i-granite ibe yinto ekhethwayo kumaqonga achanekileyo. Ngokuchaseneyo nezinye izinto ezinokuthi zande okanye zinciphe ngenxa yokutshintsha kokufuma, i-hygroscopicity ephantsi yegranite iqinisekisa ukuba ihlala izinzile ngokwemeko yendawo enamanqanaba okufuma aguquguqukayo. Olu phawu lubaluleke kakhulu kwizicelo ezifuna ukuchaneka okuphezulu, apho notshintsho oluncinci lwe-dimensional lunokukhokelela kwiimpazamo kwimilinganiselo.
Ngelixa i-granite ingathathi ukufuma ukuya kwinqanaba elibonakalayo, ukufuma okugqithisileyo kusenokuchaphazela umphezulu wayo. Ukuba ibonakaliswe kumanqanaba aphezulu okufuma ixesha elide, umphezulu wegranite unokuqokelela ukufuma okungaphezulu komphezulu, kodwa oku akwanelanga ngokubanzi ukubangela ukuguquka okanye ukulahleka kokuchaneka. Enyanisweni, xa iphathwa ngokufanelekileyo kwaye itywinwe, iiplatifomu zegranite zixhathisa kakhulu kwizinto ezisingqongileyo ezifana nokufuma, ukuhluka kobushushu, kunye nokuvezwa kweekhemikhali.
Kubalulekile ukuqaphela, nangona kunjalo, ukuba ukugcinwa okufanelekileyo kubalulekile ukugcina amaqonga egranite ekwimeko efanelekileyo. Ngelixa ukuxhathisa kwegranite ngokwendalo kukufunxa ukufuma kuyinzuzo enkulu, kusacetyiswa ukugcina la maqonga kwindawo apho kulawulwa ukufuma. Kwiindawo ezinomswakama ophezulu kakhulu, ukuqinisekisa ukuba iqonga ligcinwe kwigumbi elilawulwa yimozulu kunye neqondo lokushisa elihambelanayo kunye namanqanaba omswakama kuya kuthintela nayiphi na imiba yangaphandle ekuphembeleleni ukusebenza kwayo.
Ukuqukumbela, iiplatifomu ezichanekileyo zegranite azikho hygroscopic ngokwengqiqo yemveli, kwaye ukukwazi kwabo ukumelana nokufuma okuphezulu ngaphandle kokonakala kubenza balungele izicelo ezichanekileyo. Ukufunxa ukufuma okuphantsi kwabo kuqinisekisa ukuba bagcina ukuchaneka kobukhulu kunye nozinzo, nakwiindawo ezifumileyo. Nangona kunjalo, ukuqinisekisa ukusebenza kwexesha elide, kusacetyiswa ukuba kugcinwe kwaye kusebenze ezi ndawo kwindawo apho ubushushu kunye nokufuma kulawulwa. Ngokuqonda iipropathi zegranite kunye nokuthatha izilumkiso ezifanelekileyo, amashishini anokunyusa ngokupheleleyo amandla ezinto eziphathekayo kunye nokuzinza kwimisebenzi echanekileyo.
