Kwimeko enzima yobunjineli bokuchaneka kwanamhlanje, ukuchaneka kwezixhobo zakho zokulinganisa ezisisiseko kunokwenza okanye kwaphule ukuhambelana kwemveliso. Nangona umphezulu othe tyaba ubonakala ulula, ishishini lokuqinisekisa umgangatho lixhomekeke kwizixhobo eziqinisekisiweyo, ezenziwe ngobuchule, akukho nto iphambili kunepleyiti yomphezulu wegranite. Kwiingcali ezifuna okona kulungileyo, ukuqonda umahluko ekuchanekeni, indima yabavelisi abaqinisekisiweyo njengepleyiti yomphezulu wegranite yeZHHIMG, kunye nemfuneko yenkxaso efanelekileyo ayisiyondlela ilungileyo nje kuphela—yinto ebalulekileyo kwezoqoqosho.
Ngaphaya koBuchule: Ukuchaza amaBanga okuChaneka kwePlate yeGranite
Xa befuna isiseko sokulinganisa, iinjineli kufuneka zijonge ngaphaya kwezinto kwaye zigxile kakhulu kunyamezelo olufunyenweyo ngexesha lenkqubo yokuleqa okubalulekileyo. Olu nyamezelo luchaza ibakala, isiqinisekiso sokuba ipleyiti inamathela ngokusondeleyo kangakanani kwinqanaba eligqibeleleyo, lethiyori. Eli shishini lisebenzisa uluhlu olucacileyo, apho unyamezelo oluqinileyo luhambelana namanqanaba athile, ludla ngokulandela imigangatho efana neFederal Specification GGG-P-463c okanye iDIN 876. Incopho yokuchaneka imelwe yipleyiti yomphezulu wegranite yebakala le-AA (ngamanye amaxesha ibizwa ngokuba yiBakala 00). Ezi pleyiti zibonelela ngotshintsho oluphantsi oluvumelekileyo lokuthe tyaba kulo lonke umphezulu. Ziyindlela yokulinganisa, esetyenziswa kakhulu kwiilabhoratri eziphambili ezilawulwa yindalo ukulinganisa izixhobo ezichanekileyo kakhulu. Ukuba umsebenzi wakho ubandakanya ukuqinisekisa imigangatho yesalathiso okanye ukutyhala imida yokulinganisa ubukhulu, iBakala AA lolona khetho luvumelekileyo.
Sihla kancinci, kodwa sihlala ngaphakathi kommandla wokuchaneka kwe-elite, sifumana ipleyiti yomphezulu wegranite yebanga le-0 (okanye iBanga A). Eli banga lelona liphambili lamagumbi okuhlola abalaseleyo kunye namasebe olawulo lomgangatho. Libonelela ngokuthamba okugqwesileyo okufunekayo ekulinganiseni izixhobo zokulinganisa eziphezulu, ukwenza imisebenzi yokuseta ebalulekileyo, kunye nokuhlola iindawo ezinemilinganiselo eqinileyo. Umahluko ekunyamezeleni ukuthamba ngokubanzi phakathi kweBanga le-AA kunye neBanga le-0 ulinganiswa, kodwa kuninzi lomsebenzi wokulinganisa wesibini kunye nomsebenzi wokuhlola ophezulu, iBanga le-0 libonelela ngokulinganisela okubalaseleyo kokusebenza kunye nokusebenza. Ngelixa imigangatho isetyenziswa ngokubanzi, ukuhambelana kokufikelela kwezi nqanaba kuxhomekeke kubuchule bomenzi, izixhobo, kunye nokufunyanwa kwezinto. Iinkampani ezifana ne-ZHHIMG ziyazahlula ngokunamathela ngokungqongqo kule migangatho yamazwe ngamazwe, ukuqinisekisa ukuba xa uthenga ipleyiti yeBanga le-AA okanye yeBanga le-0, ukungaqiniseki okubhaliweyo kuthembekile kwaye kuyalandeleka. Kubathengi abaqhelene neempawu ezaziwayo, umgangatho kufuneka udlule okanye udlule ukusebenza okulindelweyo kwiyunithi ekumgangatho ophezulu, njengepleyiti yomphezulu wegranite yegrizzly, ngokugcina ulawulo oluqinileyo kuyo yonke inkqubo yokuvelisa kunye nokugqiba.
Iqhawe Elingadunyiswanga: I-Granite Surface Plate Stand
Impazamo eqhelekileyo ekusetweni kwe-metrology kukugxila kuphela kudidi lwepleyiti ngelixa ungayinaki inkxaso yayo. Ipleyiti yeGrade AA ebekwe kwisiseko esinganelanga okanye esingeyilwanga kakuhle, ngokusebenzayo, ayingcono kunepleyiti yegranite ekumgangatho ophantsi kakhulu. Ulwakhiwo oluxhasa ubunzima obunzima begranite kufuneka luthintele ukuphambuka, luhlukanise ukungcangcazela, kwaye luvumele ipleyiti ukuba ithathe indawo yayo ethe tyaba. Kulapho isitendi sepleyiti yomphezulu wegranite esikhethekileyo siba yinxalenye ebalulekileyo.
Ezi zitendi zenzelwe ngokukodwa ukuxhasa ipleyiti kwiindawo zayo ezibalwe ngokwezibalo ze-Airy Points okanye iiBessel Points. Ezi zitendi zezona ndawo zifanelekileyo zokunciphisa ukuphambuka kwepleyiti iyonke kunye nokugqwetheka ngenxa yobunzima bayo. Itheyibhile eqhelekileyo ayizukusasaza obu bunzima bukhulu ngokuchanekileyo, ize neempazamo ezinokulinganiswa kwiplani yesalathiso. Ngaphezu koko, izitendi ezisemgangathweni ophezulu zihlala zinezixhobo ezakhelwe ngaphakathi zokungcangcazela okanye iinyawo zokulinganisa, ezinceda ukwahlula ipleyiti ebuthathaka kwiintshukumo zomgangatho ezibangelwa zizixhobo ezikufutshane, ukuhamba ngeenyawo, okanye iinkqubo ze-HVAC. Oku kubaluleke kakhulu kwiipleyiti zeBanga le-AA kunye neBanga le-0 apho iintshukumo ezincinci zinokonakalisa imilinganiselo ebalulekileyo. Okokugqibela, isitendi sepleyiti yomphezulu wegranite esihle siquka ii-leveling jacks eziqinileyo ezivumela umsebenzisi ukuba alinganise ngokuchanekileyo ipleyiti. Ngelixa umxhuzulane uqinisekisa ukuba ipleyiti yomphezulu "ithe tyaba" ngokwendalo yayo yesalathiso, ukulinganisa kuyimfuneko ekusebenziseni amanqanaba e-bubble, amanqanaba e-elektroniki, kunye nezixhobo ezithile zokulinganisa (ezifana nee-column gauges) ezixhomekeke kwisalathiso esithe nkqo okanye esithe tye kwiplani yesalathiso. Ukuthenga ipleyiti yeBanga le-0 kumthengisi othembekileyo onjenge-ZHHIMG ngaphandle kwesitendi esichanekileyo lithuba elilahlekileyo. Utyalo-mali ekuchanekeni kwepleyiti luyaphazamiseka ukuba isakhiwo esixhasayo singenisa ukugqwetheka okugqitha ukunyamezela kwepleyiti.
Ityala leGranite emnyama eqinisekisiweyo
Nangona kusetyenziswa iintlobo ezahlukeneyo zegranite, iipleyiti ezichanekileyo—ingakumbi ezo zifikelela kwimigangatho yeplati yomphezulu wegranite ye-AA—zidla ngokwenziwa ngegranite emnyama (njengeDiabase emnyama okanye i-Impala Black). Le nto ayikhethwanga nje ngenxa yobuhle bayo kodwa ngenxa yeempawu zayo zomzimba eziphezulu. Igranite emnyama ngokubanzi ibonisa i-porosity ephantsi, oko kuthetha ukuba ifunxa umswakama omncinci, kwaye olu zinzo lobukhulu lubalulekile ekugcineni ukuchaneka kweplati kumanqanaba ahlukeneyo omswakama. Ikwaxinene kwaye ineModulus ephezulu ye-Elasticity kunegranite ezikhaphukhaphu, enceda ipleyiti ukuba imelane nokuphambuka phantsi kobunzima bezixhobo zokulinganisa kunye neendawo. Okubaluleke kakhulu, i-coefficient of thermal expansion (CTE) iphantsi kakhulu. Oku kuthetha ukuba ukuba ubushushu buyatshintshatshintsha kwigumbi lokuhlola, ipleyiti yegranite itshintsha ubukhulu ngaphantsi kwayo nayiphi na enye into, igcina ukuthembeka kweplani yesalathiso. Xa ukhetha imveliso yomgangatho ophezulu njengepleyiti yomphezulu wegranite ye-ZHHIMG, uthenga yonke iphakheji yesayensi yezinto, equka iimpawu eziphezulu zegranite ngokwayo, kunye nokugoba okuchwephesha.
Ukugcinwa kunye nexesha lokuphila: Ukugcina utyalo-mali lwakho
Ixesha elide lepleyiti yomphezulu wegranite yebanga le-0 okanye nasiphi na isixhobo esichanekileyo lixhomekeke ngokupheleleyo ekunyamekelweni kwayo. Ukungahoyi kungonakalisa ukuchaneka kwayo ngokukhawuleza, kuguqula iBanga le-0 libe yiBanga loku-1 okanye okubi ngakumbi, kwaye kufuneke uhlengahlengiso olubizayo okanye ukuphinda udibanise. Ukugcinwa rhoqo kuthetha ukuba umntu akufuneki asebenzise izicoci zasekhaya okanye izinto ezirhabaxa; izicoci zepleyiti yomphezulu ezikhethekileyo zenzelwe ukususa ioyile, uthuli, kunye nongcoliseko oluncinci ngaphandle kokonakalisa umphezulu. Uthuli kunye nothuli, eneneni, zezona zinto ziphambili zokuguguleka kwendawo. Ngaphezu koko, inkqubo efanelekileyo yokulayisha ifuna ukubeka izinto zokusebenza ngobunono, ungatyibiliki okanye urhuqe izinto ezinzima okanye ezirhabaxa kwigranite, njengoko ukuguguleka okubangelwa sesi senzo kuyawohloka kumphezulu ngokuhamba kwexesha. Ukunamathela kwishedyuli yokulinganisa engqongqo (ngesiqhelo iinyanga ezi-6 ukuya kwezi-12 kwiipleyiti zebanga eliphezulu ezisetyenziswa kakhulu) akunakuxoxiswana ngako. Uhlengahlengiso luqinisekisa ukuba ukuguguleka kwepleyiti kuhlala kuxhomekeke ekunyamezeleni kwayo okuqinisekisiweyo kwaye kubonelela ngerekhodi esemthethweni yokuchaneka kwayo. Ekugqibeleni, ukutyala imali kwisiseko esisemgangathweni ophezulu—nokuba yipleyiti yomphezulu wegranite ye-AA yelebhu okanye iseti eqinileyo enepleyiti yomphezulu wegranite ye-ZHHIMG kwisitendi sepleyiti yomphezulu wegranite esizinikeleyo—bubungqina bokuzinikela kwenkampani kumgangatho. Umahluko phakathi komlinganiselo ochanekileyo kunye nenxalenye engasebenziyo udla ngokuxhomekeke ekuthembekeni kwesi sixhobo sinye, esingathethiyo, nesibalulekileyo.
