Kodi Granite Precision Platform ndi Hygroscopic Motani? Kodi Idzasintha Mu Malo Ozizira?

Mapulatifomu olondola a granite amagwiritsidwa ntchito kwambiri m'mafakitale omwe amafuna kulondola kwambiri komanso kukhazikika, monga metrology ndi kupanga. Popeza ali ndi gawo lofunikira pakusunga kulondola kwa miyeso, funso limodzi lofunika nthawi zambiri limabuka: kodi granite imapangidwa bwanji, ndipo kodi imatha kusokonekera pamalo ozizira? Kumvetsetsa momwe granite imagwirira ntchito ndikofunikira kwambiri kuti mapulatifomu awa azikhala olimba komanso ogwira ntchito bwino m'mikhalidwe yosiyanasiyana yogwirira ntchito.

Granite, monga mwala wachilengedwe, imapangidwa ndi mchere wosiyanasiyana, kuphatikizapo quartz, feldspar, ndi mica. Mosiyana ndi zinthu monga matabwa kapena zitsulo zina, granite ili ndi hygroscopicity yochepa kwambiri. Izi zikutanthauza kuti simatenga chinyezi chochuluka kuchokera ku chilengedwe chozungulira, ngakhale m'malo ozizira. Kapangidwe ka mamolekyu a granite, makamaka yopangidwa ndi tinthu ta mchere tokhazikika kwambiri, imapangitsa kuti ikhale yolimba ku kutupa kapena kupindika komwe kumayambitsa kuyamwa kwa chinyezi m'zinthu zina.

Kusowa kwa kuyamwa kwa chinyezi ndi chimodzi mwa zifukwa zomwe granite imakondedwa kwambiri pa nsanja zolondola. Mosiyana ndi zipangizo zina zomwe zingakulire kapena kufupika chifukwa cha kusintha kwa chinyezi, kutsika kwa hygroscopicity ya granite kumatsimikizira kuti imakhalabe yokhazikika ngakhale m'malo omwe chinyezi chimasinthasintha. Khalidweli ndilofunika kwambiri pakugwiritsa ntchito komwe kumafuna kulondola kwambiri, komwe ngakhale kusintha pang'ono kwa kukula kungayambitse zolakwika mu miyeso.

Ngakhale granite simatenga chinyezi kwambiri, chinyezi chochuluka chingakhudzebe pamwamba pake. Ngati ipezeka pa chinyezi chochuluka kwa nthawi yayitali, pamwamba pa granite pakhoza kukhala chinyezi china pamwamba, koma izi nthawi zambiri sizikwanira kupangitsa kuti pakhale kusintha kapena kutayika kwa kulondola. Ndipotu, ikakonzedwa bwino ndikutsekedwa, nsanja za granite zimalimbana kwambiri ndi zinthu zachilengedwe monga chinyezi, kusintha kwa kutentha, komanso kuwonetsedwa ndi mankhwala.

Komabe, ndikofunikira kudziwa kuti kusamalira bwino ndikofunikira kuti nsanja za granite zikhale bwino. Ngakhale kuti granite imakana kuyamwa chinyezi ndi ubwino waukulu, ndibwinobe kusunga nsanja izi m'malo omwe chinyezi chimayendetsedwa bwino. M'malo omwe chinyezi chimakhala chambiri, kuonetsetsa kuti nsanjayo ikusungidwa m'chipinda cholamulidwa ndi nyengo chokhala ndi kutentha kofanana komanso chinyezi chofanana kudzateteza zinthu zina zakunja kuti zisakhudze magwiridwe ake.

Pomaliza, nsanja zolondola za granite sizikhala zosalala bwino m'njira yachikhalidwe, ndipo kuthekera kwawo kupirira chinyezi chambiri popanda kupotoka kumapangitsa kuti zikhale zabwino kwambiri kuti zigwiritsidwe ntchito molondola. Kuchepa kwa chinyezi chawo kumatsimikizira kuti amasunga kulondola kwawo komanso kukhazikika, ngakhale m'malo ozizira. Komabe, kuti zitsimikizire kuti zikugwira ntchito kwa nthawi yayitali, tikulimbikitsabe kusunga ndikugwiritsa ntchito nsanjazi m'malo omwe kutentha ndi chinyezi zimayendetsedwa. Pomvetsetsa mawonekedwe a granite ndikutsatira njira zoyenera zodzitetezera, mafakitale amatha kugwiritsa ntchito mphamvu ndi kukhazikika kwa zinthuzo pantchito zolondola kwambiri.
