Amapulatifomu okulinganisa i-granite, njengamathuluzi ereferensi abalulekile ekuhloleni ukunemba, adume ngobulukhuni bawo obuphezulu, i-coefficient ephansi yokwanda okushisayo, nokuzinza kwamakhemikhali okuhle kakhulu. Zisetshenziswa kabanzi ezindaweni ze-metrology kanye nezaselabhorethri. Kodwa-ke, ngokusetshenziswa isikhathi eside, lezi zinkundla azivikelekile ngokuphelele ekuguqukeni, futhi noma yiziphi izinkinga zingathinta ngokuqondile ukuthembeka kwemiphumela yokulinganisa. Izimbangela zokuguqulwa kwesikhulumi se-granite ziyinkimbinkimbi, zihlobene eduze nendawo yangaphandle, izindlela zokusetshenziswa, izindlela zokufaka, kanye nezakhiwo ezibonakalayo.
Ikakhulukazi, ukushintshashintsha kwezinga lokushisa le-ambient kanye nomswakama kuvame ukuba negalelo elibalulekile ekulimaleni kweplathifomu. Nakuba i-coefficient yokunwetshwa komugqa wegwadle iphansi uma kuqhathaniswa, ukunwetshwa okushisayo nokufinyela kusengabangela ukuqhekeka okuncane noma ukungqubuzana kwendawo lapho ukuguquka kwezinga lokushisa kudlula ±5°C. Amaplathifomu abekwe eduze kwemithombo yokushisa noma achayeke elangeni isikhathi eside asengozini enkulu yokuguquka ngenxa yomehluko owenziwe endaweni. Umthelela womswakama nawo ubalulekile. Nakuba igwadle linenani eliphansi lokumunca amanzi, ezindaweni ezinomswakama ohlobene odlula u-70%, ukungena komswakamo wesikhathi eside kunganciphisa ukuqina kwendawo futhi kubangele ukunwetshwa kwendawo, okufaka engozini ukuzinza kweplathifomu.
Ngaphezu kwezici zemvelo, ukuthwala imithwalo engafanele nakho kuyimbangela evamile yokuguqulwa. Amapulatifomu e-granite aklanywe ngomthamo olinganiselwe womthwalo, ngokuvamile ingxenye eyodwa kweshumi yamandla azo acindezelayo. Ukweqa lobu bubanzi kungaholela ekugayweni kwendawo noma ekugayweni okusanhlamvu, ekugcineni kubangele inkundla ilahlekelwe ukunemba kwayo kwasekuqaleni. Ngaphezu kwalokho, ukubekwa kwengcezu yokusebenza okungalingani kungabangela ukucindezela okukhulu ekhoneni noma endaweni, okuholela ekugxilweni kwengcindezi futhi, ngokuhamba kwesikhathi, ukuwohloka kwendawo.
Ukufakwa kwenkundla nezindlela zokuyisekela nakho kuthinta ukuzinza kwayo kwesikhathi eside. Uma ukusekela ngokwako kungeyona ileveli noma amaphuzu okusekela elayishwa ngokulinganayo, inkundla izobhekana nemithwalo engalingani ngokuhamba kwesikhathi, okubangela ukuwohloka nakanjani. Ukusekelwa kwamaphuzu amathathu kuyindlela efanelekile yamapulatifomu amancane naphakathi nendawo. Kodwa-ke, kumapulatifomu amakhulu anesisindo esingaphezu kwethani elilodwa, ukusebenzisa ukusekelwa kwamaphuzu amathathu kungabangela isikhungo seplatifomu ukuthi sizike ngenxa yesikhala esikhulu phakathi kwamaphoyinti okusekela. Ngakho-ke, amapulatifomu amakhulu ngokuvamile adinga izakhiwo zokusekela eziningi noma ezintantayo ukuze asabalalise ingcindezi.
Ngaphezu kwalokho, nakuba i-granite iguga ngokwemvelo, ukukhululwa kwengcindezi eyinsalela ngokuhamba kwesikhathi kusengadala ukuguga okuncane. Uma izinto ezine-asidi noma ezine-alkali zikhona endaweni yokusebenza, ukwakheka kwezinto ezibonakalayo kungase kugqwelwe ngamakhemikhali, kunciphise ukuqina kwendawo futhi kuphazamise nakakhulu ukunemba kweplathifomu.
Ukuvimbela nokunciphisa lezi zinkinga, izinyathelo eziningi zokuvimbela kufanele zisetshenziswe. Indawo ekahle yokusebenza kufanele igcine izinga lokushisa elingu-20±2°C nezinga lomswakamo elingu-40%-60%, kugwenywe ukukhanya kwelanga nemithombo yokushisa. Ngesikhathi sokufakwa, sebenzisa abakaki abahlukanisayo bokudlidliza noma amaphedi erabha, futhi uqinisekise ngokuphindaphindiwe izinga usebenzisa ileveli noma isihloli sikagesi. Ngesikhathi sokusetshenziswa kwansuku zonke, umthamo womthwalo olinganiselwe kufanele ulandelwe ngokuqinile. Izingcezu zokusebenza kufanele zigcinwe ku-80% womthwalo omkhulu, futhi kufanele zihlakazwe ngangokunokwenzeka ukuze kugwenywe ukugxiliswa kwengcindezi yendawo. Kumapulatifomu amakhulu, ukusebenzisa isakhiwo sokusekela amaphuzu amaningi kunganciphisa kakhulu ingozi yokuguqulwa ngenxa ye-deadweight.
Ukunemba kwamapulatifomu egwadle kudinga ukuhlolwa nokunakekelwa njalo. Ngokuvamile kunconywa ukwenza ukuhlolwa kwe-flatness njalo ezinyangeni eziyisithupha. Uma iphutha lidlula ukubekezelelana okujwayelekile, iplatifomu kufanele ibuyiselwe efekthri ukuze igaywe kabusha noma ilungiswe. Imihuzuko emincane noma imigodi endaweni yesikhulumi ingalungiswa ngedayimane lokunamathisela abrasive ukuze kubuyiselwe ubulukhuni obungaphezulu. Kodwa-ke, uma i-deformation inzima futhi kunzima ukuyilungisa, isiteji kufanele sishintshwe ngokushesha. Uma ingasetshenziswa, kuhle ukumboza inkundla ngeshidi elingangeni uthuli ukuze uvimbele ukunqwabelana kothuli futhi uligcine endaweni eyomile, engenawo umoya. Ngesikhathi sokuthutha, sebenzisa ibhokisi lezinkuni kanye nezinto zokuguqa ukuze uvimbele ukudlidliza namaqhubu.
Ngokuvamile, ngenkathi amapulatifomu wokulinganisa i-granite enikeza izakhiwo ezinhle kakhulu zomzimba, azithinteki ngokuphelele ekuguquguqukeni. Ngokulawulwa kwemvelo okufanele, ukwesekwa okukhwezwayo okufanele, ukuphathwa kwemithwalo okuqinile, nokugcinwa okuvamile, ingozi yokuguquguquka ingancishiswa kakhulu, iqinisekise ukunemba okungaguquki nokuzinza ekusetshenzisweni kwesikhathi eside, okuhlinzeka ukwesekwa okuthembekile kokulinganisa ukunemba.
