Ama-granite parallel gauges ayithuluzi lokulinganisa ukunemba elibalulekile, futhi ubuqotho bokuthamba kwawo kobuso buthinta ngqo ukunemba kokulinganisa. Ukuhlanza noma ukuphatha okungalungile kungabangela imihuzuko, ukugqwala, noma izinguquko ezincane ezimpahleni zetshe, okubeka engcupheni ukunemba kwalo. Ukugcina la mathuluzi kudinga ukunakwa ngokucophelela ezindleleni zokuhlanza, izinto zokwakha, kanye nezimo zemvelo.
Ngaphambi kokuhlanza, kubalulekile ukulungiselela indawo elawulwayo, engenalo uthuli. Igeyiji kufanele ibekwe endaweni eyomile, ezimele ukuze kuvinjelwe izinhlayiya eziphuma emoyeni, izingcezu zensimbi, noma izinsalela zamafutha ukuthi zingangcolisi indawo. Wonke amathuluzi okuhlanza, kufaka phakathi izindwangu ezithambile, iziponji, namabhulashi, kumele ahlanzwe kahle futhi ahlolwe ukuze kususwe noma yiziphi izinhlayiya ezikhululekile noma izinhlayiya eziqinile ezingaklwebha i-granite. Ukuqonda uhlobo lwamabala—kungakhathaliseki ukuthi anamafutha, ane-acid, noma asekelwe ku-pigment—kuyasiza futhi ekunqumeni indlela yokuhlanza ephumelela kakhulu.
Ukukhetha into yokuhlanza efanele kubaluleke ngokulinganayo. I-granite iyazwela kuma-acid nama-alkaline aqinile, ngakho-ke kufanele kusetshenziswe izihlanzi ezingathathi hlangothi kuphela ezine-pH ephakathi kuka-6 no-8. Izihlanzi zasekhaya ezinolaka, njengalezo eziqukethe i-sodium hydroxide, kumele zigwenywe, njengoba zingalimaza ubuso betshe. Kumabala aqinile, izihlanzi zamatshe ezikhethekile zingasetshenziswa ngemuva kokuhlola indawo encane, engabonakali amahora angama-24 ukuqinisekisa ukuthi akukho mbala noma ukulahleka kokukhanya okwenzekayo. Izinto zokuhlanza ezahlukene akufanele zihlanganiswe, njengoba ukusabela kwamakhemikhali kungakhiqiza amagesi ayingozi noma kunciphise ukusebenza kahle kokuhlanza.
Ngesikhathi sokuhlanza, ukugcina indlela yokusula ehambisanayo kanye nokucindezela okuthambile kubalulekile. Sula njalo ngendlela eyodwa ehambisana nebhulashi noma indwangu ukuze ugweme ukuklwebheka okuncane. Amabhulashi athambile kufanele asetshenziswe emaphethelweni ukuvikela ama-chamfer. Ngemva kokuhlanza, hlanza kahle ngamanzi ahlanzekile noma ahlanziwe ukuze uvimbele ukuchithwa kwamaminerali bese womisa usebenzisa izindwangu ezingenayo i-lint noma umoya wemvelo. Ukushisa noma ukukhanya kwelanga okuqondile kufanele kugwenywe, njengoba izinguquko zokushisa ezisheshayo zingabangela ukuqhekeka.
Kumelwe kuqashelwe ngokukhethekile amabala aphuthumayo kanye nokugcinwa kwesikhathi eside. Izinto ezine-asidi, njengejusi yezithelo noma uviniga, kufanele zihlanzwe ngokushesha futhi zisuswe nge-ammonia exutshwe ngamanzi ngenkathi ugqoke amagilavu okuzivikela. Imihuzuko emincane yensimbi ingapholishwa ngobumnene nge-powder yokupholishwa ngamatshe kanye ne-felt, kodwa umonakalo omkhulu kufanele uphathwe yizinsizakalo zobungcweti. Amabala aqhubekayo angene ebusweni be-granite adinga ukwelashwa okukhethekile kokuhlanza kanye nokwakheka kwamakristalu ukuze kubuyiselwe ukuthamba nokucwebezela.
Ukugcinwa okuqhubekayo kubalulekile ukuqinisekisa ukunemba kwesikhathi eside. Ukufaka i-sealant engena njalo ezinyangeni eziyisithupha kudala isithiyo sokuvikela amabala, uma nje indawo yomile futhi i-sealant imuncwa ngokulinganayo. Ukugcinwa okufanele nakho kubalulekile; ama-gauge kufanele alale ngokuvundlile kuma-raber mat noma ezisekelweni zokhuni, agweme ukuthintana ngqo nensimbi noma izindawo eziqinile, ngokushintshashintsha kwezinga lokushisa okulawulwayo ngaphakathi kuka-±5℃ kanye nomswakama ongaphansi kuka-60%. Ukulinganisa ngezikhathi ezithile kusetshenziswa ama-laser interferometers noma amazinga kagesi kuyadingeka ukuqinisekisa ukuthi amazinga okulinganisa ayagcinwa. Noma yikuphi ukuphambuka okutholiwe kufanele kushukumise ukumiswa ngokushesha kokusetshenziswa nokulungiswa kochwepheshe.
Ngokuhlanganisa ukuhlanza ngokucophelela, ukusetshenziswa okufanele kwemikhiqizo ephephile ngamatshe, ukuphathwa kahle, kanye nokugcinwa njalo, isikhathi sokuphila kanye nokunemba kwama-granite parallel gauges kungagcinwa ngempumelelo. Ngezinselele zokuhlanza eziyinkimbinkimbi noma ukunakekelwa okukhethekile, ukubonisana nensizakalo yokunakekelwa kwamatshe ochwepheshe kunconywa kakhulu ukuvimbela umonakalo ongenakuguqulwa nokuqinisekisa ukunemba okuqhubekayo ekulinganisweni.
