Granite vs. Marble mu Zida Zolondola: Chifukwa Chake Kuchuluka ndi Kukhazikika Ndikofunikira

Pitani ku labu iliyonse ya metrology, chipinda cha CMM, kapena nsalu ya semiconductor, ndipo mupeza chidutswa cha miyala yakuda pansi pa zidazo. Kwa munthu wosaphunzira, granite ndi marble zimaoneka ngati zosinthika — zonse ndi miyala yosweka, zonse zimatha kupukutidwa mpaka kumalizidwe ndi galasi, zonse zimawoneka "zolimba." Pakupanga molondola, kufanana kumeneko kumatha nthawi yomwe mumayamba kuyeza pamlingo wa micron.

Kuchulukana Si Tsatanetsatane Wokongoletsa

Marble ndi mwala wosinthika womwe umapangidwa makamaka kuchokera ku calcite kapena dolomite yobwezeretsedwanso. Kapangidwe kake ka kristalo ndi kofewa komanso kokhala ndi mabowo poyerekeza ndi granite ya igneous, yomwe imapangidwa kuchokera ku magma yozizira pang'onopang'ono ndipo imakhala ndi mchere wolimba monga quartz ndi feldspar. Kusiyana kwa kapangidwe kake kumawonekera mwachindunji mu kuchulukana: granite wakuda womwe umagwiritsidwa ntchito popanga maziko olondola nthawi zambiri umakhala pafupifupi 3,000–3,100 kg/m³, wokhuthala kwambiri kuposa marble ambiri ogulitsa.

Kuchulukana kwa zinthu n'kofunika chifukwa kumagwirizana ndi kuuma kwa mkati ndi kukana kukwawa — kusintha pang'onopang'ono komanso kosatha komwe chinthu chimadutsa pansi pa katundu wokhazikika kapena kulemera kwake. Mbale ya granite pamwamba pake imathandiziramakina oyezera ogwirizana(CMM) kapena makina owunikira owonera amafunika kukhala osalala kwa zaka zambiri, osati miyezi ingapo. Chipangizo chokhala ndi kachulukidwe kochepa komanso kapangidwe ka mkati kokhala ndi mabowo ambiri chimakhala chosavuta kusuntha pang'onopang'ono, kuyamwa chinyezi, komanso kusweka pang'onopang'ono chifukwa cha kutentha.

Chifukwa Chake Ogulitsa Ena Amalowa M'malo mwa Marble

Marble ndi wotsika mtengo poyerekeza ndi miyala yamtengo wapatali ndi makina, ndipo miyala yomalizidwa ikhoza kukhala yovuta kusiyanitsa ndi granite yomwe idapukutidwa ndi utoto wakuda. Mumsika womwe ogula nthawi zambiri sangayese kuchulukana kapena kukhazikika kwa nthawi yayitali asanagule, izi zimapangitsa kuti pakhale malo olakwika olembera - kugulitsa zinthu zopangidwa ndi marble ngati maziko a "granite". Zotsatira zake sizokongoletsa; ndi njira yoyezera yomwe imataya pang'onopang'ono kuwerengera, nthawi zambiri popanda chifukwa chodziwikiratu mpaka miyeso yobwerezabwereza itayamba kuyenda.

Zoyenera Kuyang'ana Musanagule

Kwa mainjiniya omwe amatchula maziko a granite, macheke angapo amathandiza kusiyanitsa granite yeniyeni yolondola ndi malo ena otsika:

• Funsani ziwerengero za kuchulukana kwa anthu, zomwe zingatsimikizidwe ndi labu ya chipani chachitatu osati zomwe zanenedwa pa pepala la data.
• Pemphani kuti muzitha kutsata bwino zinthu — mapepala apamwamba ayenera kutumizidwa ndi satifiketi yosalala yomwe ingatsatidwe ku bungwe la dziko lonse la metrology.
• Yang'anani kapangidwe ka tirigu pansi pa kukula kwake; granite yeniyeni ya igneous ikuwonetsa mawonekedwe a kristalo okhwima, olumikizana, pomwe kapangidwe ka kristalo ka marble ndi kosalala komanso kofanana.
• Yang'anani deta yokulitsa kutentha, popeza kuchuluka kwa kutentha komwe granite imakulitsa kutentha ndi chimodzi mwa zifukwa zazikulu zomwe imakondera kugwiritsa ntchito zida zomwe zimakhudzidwa ndi kutentha monga ma CMM ndi mabenchi optical.

Pamene kupanga molondola kukupitiliza kukulitsa kulekerera kolimba — kusalala kwa nanometer pa mbale zapamwamba tsopano kwatheka — kusankha kwa zinthu zopangira sikulinso chinthu chofunikira kwambiri ndipo kumakhala chinthu chomwe chimatsimikizira nthawi yomwe chipangizocho chikhala cholondola. Makampani monga ZHHIMG, omwe amapanga zigawo za granite ndi zida zoyezera pamlingo, amaona kutsimikizira kuchuluka kwa zinthu ngati gawo lokhazikika la kuwongolera khalidwe chifukwa kusiyana pakati pa maziko okhazikika ndi omwe akusunthika pang'onopang'ono nthawi zambiri sikuonekera mpaka zitachedwa.
