Kodi Granite Precision Platform ndi Hygroscopic bwanji? Kodi Idzawonongeka M'malo Achinyezi?

Mapulatifomu olondola a granite amagwiritsidwa ntchito kwambiri m'mafakitale omwe amafuna kulondola komanso kukhazikika, monga metrology ndi kupanga. Poganizira gawo lawo lofunikira pakusunga zolondola, funso limodzi lofunikira nthawi zambiri limabuka: Kodi hygroscopic ndi granite, ndipo ingapunduke m'malo achinyezi? Kumvetsetsa mawonekedwe a hygroscopic a granite ndikofunikira pakuwonetsetsa kuti nsanjazi zikukhalabe zokhazikika komanso zimagwira ntchito zosiyanasiyana.

Granite, monga mwala wachilengedwe, amapangidwa ndi mchere wosiyanasiyana, kuphatikiza quartz, feldspar, ndi mica. Mosiyana ndi zinthu monga matabwa kapena zitsulo zina, granite ili ndi hygroscopicity yochepa kwambiri. Izi zikutanthauza kuti sichimamwa chinyezi chambiri kuchokera kumadera ozungulira, ngakhale pamvula. Mapangidwe a mamolekyu a granite, omwe amapangidwa makamaka ndi njere zamchere zokhazikika, zimapangitsa kuti zisawonongeke ndi kutupa kapena kupindika komwe kumayambitsa kuyamwa kwa chinyezi muzinthu zina.

Kusayamwa kwakukulu kwa chinyezi ndi chimodzi mwazifukwa zomwe granite ndizomwe zimakondedwa pamapulatifomu olondola. Mosiyana ndi zida zina zomwe zimatha kukula kapena kutsika chifukwa cha kusintha kwa chinyezi, kutsika kwa granite kumapangitsa kuti ikhalebe yokhazikika ngakhale m'malo omwe chinyezi chimasintha. Izi ndizofunikira makamaka pamapulogalamu omwe amafunikira kulondola kwambiri, komwe ngakhale kusintha pang'ono kungayambitse zolakwika mumiyeso.

Ngakhale kuti granite sichimamwa chinyezi mpaka kufika pamtunda, chinyezi chambiri chimakhudzabe pamwamba pake. Ngati pamakhala chinyezi chambiri kwa nthawi yayitali, pamwamba pa granite imatha kuwunjikana ndi chinyezi chambiri, koma nthawi zambiri izi sizokwanira kupangitsa kupindika kapena kutaya kulondola. M'malo mwake, akasamalidwa bwino ndikusindikizidwa, nsanja za granite zimalimbana kwambiri ndi zinthu zachilengedwe monga chinyezi, kusiyanasiyana kwa kutentha, komanso kuwonekera kwamankhwala.

Ndikofunika kuzindikira, komabe, kuti kukonza bwino ndikofunikira kuti nsanja za granite zisungidwe bwino. Ngakhale kukana kwachilengedwe kwa granite kukana kuyamwa chinyezi ndikwabwino kwambiri, ndibwinobe kusunga nsanjazi m'malo omwe chinyezi chimayendetsedwa. M'madera omwe ali ndi chinyezi chambiri, kuonetsetsa kuti nsanjayo imasungidwa m'chipinda choyendetsedwa ndi nyengo ndi kutentha kosasinthasintha ndi kutentha kwa chinyezi kudzalepheretsa zinthu zilizonse zakunja zomwe zingakhudze ntchito yake.

Pomaliza, mapulaneti olondola a granite sakhala a hygroscopic mwanjira yanthawi zonse, ndipo kuthekera kwawo kupirira chinyezi chambiri popanda kupunduka kumawapangitsa kukhala abwino kuti agwiritse ntchito moyenera. Mayamwidwe awo otsika amawapangitsa kuti azikhala olondola komanso okhazikika, ngakhale m'malo achinyezi. Komabe, kuti zitsimikizire kuti zikugwira ntchito kwanthawi yayitali, zimalimbikitsidwabe kusunga ndikugwiritsa ntchito nsanjazi m'malo omwe kutentha ndi chinyezi zimayendetsedwa. Pomvetsetsa momwe ma granite amagwirira ntchito komanso kusamala koyenera, mafakitale amatha kugwiritsa ntchito mphamvu ndi kukhazikika kwa zinthuzo pantchito zolondola kwambiri.
