Amapulatifomu okunemba kwe-granite asetshenziswa kabanzi ezimbonini ezidinga ukunemba okuphezulu kanye nokuqina, njenge-metrology kanye nokukhiqiza. Njengoba kunendima ebalulekile ekugcineni ukunemba kobukhulu, umbuzo owodwa obalulekile uvame ukuvela: i-granite i-hygroscopic kangakanani, futhi ingabe ingaguquguquka endaweni enomswakama? Ukuqonda izakhiwo ze-hygroscopic ze-granite kubalulekile ukuqinisekisa ukuthi lawa mapulatifomu agcina ukuzinza nokusebenza kwawo ezimweni zokusebenza ezahlukahlukene.
I-granite, njengetshe lemvelo, yakhiwe ngamaminerali ahlukahlukene, okuhlanganisa i-quartz, i-feldspar, ne-mica. Ngokungafani nezinto ezifana nokhuni noma izinsimbi ezithile, i-granite ine-hygroscopicity ephansi kakhulu. Lokhu kusho ukuthi ayimunci umswakama omningi ovela endaweni ezungezile, ngisho nasezimweni ezinomswakama. Isakhiwo sama-molecule e-granite, esakhiwe ngokuyinhloko ngama-mineral grain aqinile kakhulu, siyenza imelane nokuvuvukala noma ukugoba okubangelwa ukumuncwa komswakama kwezinye izinto.
Ukungabikho kokumuncwa komswakama okukhulu kungenye yezizathu ezenza i-granite ibe yinto ekhethwayo yamapulatifomu okunemba. Ngokungafani nezinye izinto ezingase zande noma zinciphe ngenxa yokushintsha komswakama, i-hygroscopicity ephansi ye-granite iqinisekisa ukuthi ihlala izinzile ngosayizi ngisho nasezindaweni ezinamazinga omswakama ashintshashintshayo. Lesi sici sibaluleke kakhulu ekusetshenzisweni okudinga ukunemba okuphezulu, lapho ngisho nezinguquko ezincane zobukhulu zingaholela emaphutheni ekulinganisweni.
Nakuba i-granite ingamunci umswakama ngezinga elibonakalayo, umswakama owedlulele usengathinta ubuso bayo. Uma ivezwa emazingeni aphezulu omswakama isikhathi eside, ubuso be-granite bungase buqongelele umswakama othile womphezulu, kodwa lokhu ngokuvamile akwanele ukubangela ukuguquka noma ukulahlekelwa ukunemba. Eqinisweni, uma iphathwa kahle futhi ivalwe, amapulatifomu e-granite amelana kakhulu nezici zemvelo ezifana nomswakama, ukushintshashintsha kwezinga lokushisa, kanye nokuvezwa kwamakhemikhali.
Nokho, kubalulekile ukuqaphela ukuthi ukulungiswa okufanele kubalulekile ukuze kugcinwe amapulatifomu e-granite esesimweni esihle kakhulu. Nakuba ukumelana kwe-granite nokumuncwa komswakama kuyinzuzo enkulu, kusanconywa ukugcina la mapulatifomu ezindaweni lapho kulawulwa khona umswakama. Ezindaweni ezinomswakama ophezulu kakhulu, ukuqinisekisa ukuthi ipulatifomu igcinwa egumbini elilawulwa yisimo sezulu elinamazinga okushisa nomswakama ahambisanayo kuzovimbela noma yiziphi izici zangaphandle ukuthi zingathonyi ukusebenza kwayo.
Ekuphetheni, amapulatifomu okunemba kwe-granite awawona ama-hygroscopic ngomqondo wendabuko, futhi ikhono lawo lokubekezelela umswakama ophezulu ngaphandle kokuguquka liwenza afaneleke kakhulu ekusetshenzisweni okunembile. Ukumuncwa kwawo komswakama okuphansi kuqinisekisa ukuthi agcina ukunemba kwawo kobukhulu kanye nokuqina, ngisho nasezindaweni ezinomswakama. Kodwa-ke, ukuqinisekisa ukusebenza kwesikhathi eside, kusanconywa ukugcina nokusebenzisa la mapulatifomu ezindaweni lapho izinga lokushisa kanye nomswakama kulawulwa khona. Ngokuqonda izakhiwo ze-granite kanye nokuthatha izinyathelo ezifanele zokuqapha, izimboni zingasebenzisa ngokugcwele amandla kanye nokuqina kwezinto zokwakha ukuze zenze imisebenzi enembile kakhulu.
