Amapulatifomu okulinganisa i-granite, njengamathuluzi okubhekisela abalulekile ekuhlolweni okunembile, aziwa ngokuqina kwawo okuphezulu, i-coefficient yokukhulisa ukushisa okuphansi, kanye nokuqina kwamakhemikhali okuhle kakhulu. Asetshenziswa kabanzi ezindaweni ze-metrology kanye ne-laboratory. Kodwa-ke, uma esetshenziswa isikhathi eside, lawa mapulatifomu awavikelekile ngokuphelele ekuguqukeni, futhi noma yiziphi izinkinga zingathinta ngqo ukuthembeka kwemiphumela yokulinganisa. Izimbangela zokuguqulwa kwepulatifomu ye-granite ziyinkimbinkimbi, zihlobene eduze nendawo yangaphandle, izindlela zokusebenzisa, izindlela zokufaka, kanye nezakhiwo zezinto ezibonakalayo.
Ngokuyinhloko, ukuguquguquka kwezinga lokushisa elizungezile kanye nomswakama kuvame ukuba nomthelela omkhulu ekuguqukeni kwepulatifomu. Nakuba i-coefficient yokwanda okuqondile kwe-granite iphansi kakhulu, ukwanda nokuncipha kokushisa kungabangela imifantu emincane noma ukugoba kwendawo lapho ukuguquguquka kwezinga lokushisa kudlula ±5°C. Amapulatifomu abekwe eduze kwemithombo yokushisa noma abekwe elangeni isikhathi eside asengozini enkulu yokuguqulwa ngenxa yokwehluka kwezinga lokushisa kwendawo. Umthelela womswakama nawo ubalulekile. Nakuba i-granite inesilinganiso esiphansi sokumuncwa kwamanzi, ezindaweni ezinomswakama olinganiselwe odlula 70%, ukungena komswakama isikhathi eside kunganciphisa ubulukhuni bomphezulu futhi kubangele nokwanda kwendawo, okubeka engcupheni ukuzinza kwepulatifomu.
Ngaphezu kwezici zemvelo, ukuthwala umthwalo ngendlela engafanele nakho kuyimbangela evamile yokuguquka. Amapulatifomu e-granite aklanywe ngomthamo womthwalo olinganiselwe, ngokuvamile ingxenye eyodwa kweziyishumi zamandla awo okucindezela. Ukudlula leli banga kungaholela ekuchotshozweni kwendawo noma ekuqhekekeni kwezinhlamvu, ekugcineni kubangele ukuthi ipulatifomu ilahlekelwe ukunemba kwayo kwasekuqaleni. Ngaphezu kwalokho, ukubekwa okungalingani kwezingxenye zomsebenzi kungabangela ukucindezela okukhulu ekhoneni noma endaweni, okuholela ekugxileni kokucindezeleka futhi, ngokuhamba kwesikhathi, ukuguqulwa kwendawo.
Izindlela zokufaka kanye nokusekela kwepulatifomu nazo zithinta ukuzinza kwayo kwesikhathi eside. Uma ukwesekwa ngokwako kungalingani noma amaphuzu okusekela elayishwe ngokungalingani, ipulatifomu izobhekana nemithwalo engalingani ngokuhamba kwesikhathi, okubangela ukuguguleka ngokungenakugwenywa. Ukusekelwa kwamaphuzu amathathu kuyindlela efanelekile yamapulatifomu amancane naphakathi nendawo. Kodwa-ke, kumapulatifomu amakhulu anesisindo esingaphezu kwethani elilodwa, ukusebenzisa ukwesekwa kwamaphuzu amathathu kungabangela ukuthi isikhungo sepulatifomu sicwile ngenxa yesikhala esikhulu phakathi kwamaphuzu okusekela. Ngakho-ke, amapulatifomu amakhulu avame ukudinga izakhiwo eziningi zokusekela noma ezintantayo ukuze kusatshalaliswe ukucindezeleka.
Ngaphezu kwalokho, yize i-granite iguga ngokwemvelo, ukukhishwa kokucindezeleka okusele ngokuhamba kwesikhathi kungabangela ukuguquka okuncane. Uma kukhona izinto ezine-asidi noma i-alkaline endaweni yokusebenza, isakhiwo sezinto singase siguge ngamakhemikhali, kuncishiswe ubulukhuni bomphezulu futhi kuthinte kakhulu ukunemba kwepulatifomu.
Ukuze kuvinjelwe futhi kuncishiswe lezi zinkinga, kufanele kusetshenziswe izinyathelo eziningi zokuvimbela. Indawo yokusebenza efanele kufanele igcine izinga lokushisa elingu-20±2°C kanye nezinga lomswakama elingu-40%-60%, kugwenywe ukukhanya kwelanga okuqondile kanye nemithombo yokushisa. Ngesikhathi sokufakwa, sebenzisa amabhulakhethi okuhlukaniswa kokudlidliza noma amaphedi enjoloba, futhi uqinisekise ngokuphindaphindiwe izinga usebenzisa isivivinyo sezinga noma se-elekthronikhi. Ngesikhathi sokusetshenziswa kwansuku zonke, umthamo womthwalo olinganiselwe kumele ulandelwe ngokuqinile. Izinto zokusebenza kufanele zigcinwe ngaphakathi kuka-80% womthwalo omkhulu, futhi kufanele zibekwe zihlakazeke ngangokunokwenzeka ukuze kugwenywe ukugcwala kwengcindezi yendawo. Kumapulatifomu amakhulu, ukusebenzisa isakhiwo sokusekela esinamaphuzu amaningi kunganciphisa kakhulu ingozi yokuguquguquka ngenxa yobunzima obungalingani.
Ukunemba kwamapulatifomu e-granite kudinga ukuhlolwa nokugcinwa njalo. Ngokuvamile kunconywa ukuthi kwenziwe ukuhlolwa kokuthamba njalo ezinyangeni eziyisithupha. Uma iphutha lidlula ukubekezelelana okujwayelekile, ipulatifomu kufanele ibuyiselwe efektri ukuze igaywe kabusha noma ilungiswe. Imihuzuko emincane noma imigodi ebusweni bepulatifomu ingalungiswa nge-diamond abrasive paste ukuze kubuyiselwe ubulukhuni bomphezulu. Kodwa-ke, uma ukuguquguquka kukhulu futhi kunzima ukulungisa, ipulatifomu kufanele ishintshwe ngokushesha. Uma ingasetshenziswa, kungcono ukumboza ipulatifomu ngeshidi elingangeni uthuli ukuze uvimbele ukunqwabelana kothuli bese uyigcina endaweni eyomile, enomoya opholile. Ngesikhathi sokuthuthwa, sebenzisa ibhokisi lokhuni nezinto zokubopha ukuze uvimbele ukudlidliza kanye nokuqhuma.
Ngokuvamile, nakuba amapulatifomu okulinganisa i-granite enikeza izakhiwo ezinhle kakhulu zomzimba, awathinteki ngokuphelele ekuguqukeni. Ngokulawulwa kwemvelo okufanele, ukwesekwa okufanele kokufakwa, ukuphathwa komthwalo okuqinile, kanye nokugcinwa njalo, ingozi yokuguquka ingancishiswa kakhulu, kuqinisekiswe ukunemba okuqhubekayo kanye nokuqina kokusetshenziswa kwesikhathi eside, kuhlinzekwe ukwesekwa okuthembekile kokulinganisa okunembile.
