Pankhani yopanga zinthu molondola, kukhulupirika ndi kulondola kwa zida zoyezera ndikofunikira kwambiri kuti zinthu zomaliza zikhale bwino. Mapulatifomu a granite, omwe nthawi zambiri amagwiritsidwa ntchito ngati maziko a makina oyezera ogwirizana (CMMs), zida zowunikira, ndi makina osiyanasiyana, ayenera kusunga kulondola kwawo pansi pa mikhalidwe yosiyanasiyana ya katundu. Kutha kwa mapulatifomu awa kunyamula katundu sikutanthauza kuti ndi chinthu chimodzi chokha, chifukwa mapulatifomu amapangidwira kukwaniritsa zofunikira zinazake kutengera kulemera komwe akuyembekezeka kunyamula. Kuyambira pa mitundu yopepuka mpaka mayankho olemera, kumvetsetsa kusiyana kwa kapangidwe ka mapulatifomu a granite ndikofunikira kwambiri kuti zitsimikizire kuti zikugwira ntchito bwino m'mafakitale osiyanasiyana.
Mapulatifomu a granite ndi ofunikira kuti apereke malo okhazikika, ndipo mphamvu zawo zonyamula katundu ndizofunikira kwambiri pakusunga kusalala ndikuchepetsa kusintha kwa zinthu panthawi yogwiritsa ntchito. Mapulatifomu awa ayenera kupangidwa ndi kupangidwa ndi zipangizo, kapangidwe, ndi njira zokonzera zinthu zomwe zimagwirizana ndi ntchito zomwe akufuna. Kaya nsanjayo ikuthandiza zida zopepuka kapena makina olemera, ndikofunikira kusankha kapangidwe koyenera kuti zitsimikizire kulondola kwa nthawi yayitali.
Pa nsanja zopepuka za granite, nthawi zambiri zomwe zimakhala zosakwana 500 kg, kapangidwe kake kamakhala kozungulira kulinganiza bwino kwambiri komanso kapangidwe kopepuka. Mapulatifomu awa amagwiritsidwa ntchito makamaka m'malo omwe kulondola kwambiri kumafunika, koma kulemera kwa nsanjayo kuyenera kuchepetsedwa. Zipangizo monga granite yakuda ya mica ya grain, yokhala ndi quartz ya 30% kapena kuposerapo, imagwiritsidwa ntchito kwambiri. Zipangizozi zimapereka kuchuluka kwabwino kwa 2.6–2.7g/cm², kuonetsetsa kuti kulimba kwake kukhale kotsika pamene kuchepetsa kulemera. Kukhuthala kwa nsanjayi nthawi zambiri kumakhala pakati pa 50 ndi 80 mm pa chitsanzo cha 1m × 1m, ndipo kapangidwe kake kamakhala ndi kapangidwe kopanda kanthu pansi pake. Ndi nthiti zomwe zili ndi mtunda wa 200–300mm ndipo zili ndi m'lifupi wa 30mm ndi kutalika kwa 40mm, kapangidwe kameneka kamapereka mgwirizano wabwino pakati pa mphamvu ndi kuchepetsa kulemera, zomwe zimapangitsa kuti ikhale yopepuka ndi 30% kuposa nyumba zolimba. Kuphatikiza apo, ma frequency a resonance a nsanjayi ndi opitilira 50Hz, zomwe zimathandiza kupewa kusokonezeka ndi kugwedezeka.
Kulondola kwa kapangidwe ka nsanja izi ndikofunikiranso. Kusalala kwa malo ogwirira ntchito nthawi zambiri kumayendetsedwa mpaka pansi pa 0.005mm/100mm, kuonetsetsa kuti palibe kusintha kulikonse ngakhale mutanyamula katundu wochepa.nsanja za graniteamagwiritsidwa ntchito kwambiri popanga zida zamagetsi, kukonza zida zazing'ono, ndi ntchito zina zofanana pomwe kukhudzana ndi nsanjayi kumawonjezera 60% ya malo onse oyendetsera, kupewa kupanikizika kwakukulu pamalo omwe alipo.
Mapulatifomu apakati, kuyambira 500 kg mpaka 5000 kg, amapangidwa ndi zinthu zosiyanasiyana zofunika. Ngakhale kuti amasunga kulondola kwakukulu, mapulatifomu awa ayenera kulandira katundu wokulirapo. Pamapulatifomu awa, granite wapakati ndi woyenera, nthawi zambiri wokhala ndi feldspar ya 40%–50%. Kuchuluka kwake kumawonjezeka kufika pa 2.7–2.8g/cm³, ndipo makulidwe a nsanjayo amakwezedwa kufika pa 100–150mm pa chitsanzo cha 1m × 2m. Pansi pake pali kapangidwe kolimbikitsidwa ndi gridi, komwe nthiti zazikulu zimakhala 50mm m'lifupi, ndipo nthiti zopingasa zimakhala 30mm m'lifupi, zomwe zimapangitsa gridi ya 100×100mm. Malo opsinjika amazunguliridwa pamakona kuti achepetse kukhudzika. Kapangidwe ka gridi iyi kamatsimikizira kuti nsanjayo imasunga mphamvu zake ndikuchepetsa kupindika.
Kuti zikhale zolondola kwambiri, nsanja izi nthawi zambiri zimakhala ndi malo olumikizirana (12–16mm mulifupi) oikira zida, ndi malo olumikizirana kuyambira 100mm mpaka 150mm. Malo olumikiziranawo amayikidwa kuti apewe kufooketsa mphamvu ya nsanjayo, ndi mtunda wochepera 30mm kuchokera pansi. Pakuyika, zothandizira zosinthika zimagwiritsidwa ntchito kugawa katundu mofanana, ndi malo anayi othandizira pa mita imodzi ya sikweya, kuonetsetsa kuti kusiyana kwa katundu kumakhala mkati mwa 5%. Mapulatifomu awa nthawi zambiri amagwiritsidwa ntchito mumakina oyezera ogwirizana, kuyang'anira nkhungu yapakatikati, ndi ntchito zina zofanana, komwe kupotoka kwakukulu komwe kungaloledwe ndi ≤ L/10000 (L kukhala kutalika kwa nsanjayo).
Mapulatifomu olemera, opangidwira katundu woposa 5000 kg, amamangidwa kuti asasinthe zinthu pogwiritsa ntchito zolemera zazikulu. Mapulatifomu awa amapangidwa ndi granite wopangidwa ndi tinthu tating'onoting'ono, okhala ndi makristaro a quartz opitilira 2mm, ndipo ali ndi kachulukidwe kopitilira 2.8g/cm³. Mphamvu yopondereza ya chinthuchi nthawi zambiri imakhala yoposa 200 MPa, ndipo makulidwe a nsanjazi amakhala pakati pa 200 mpaka 300mm pa chitsanzo cha 2m × 3m. Kapangidwe kake ndi kolimba, ndi maziko olimba (50mm makulidwe) omwe amalumikizana ndi nsanja yayikulu kudzera mu maziko ooneka ngati dzira okhala ndi epoxy resin bonding (yokhala ndi mphamvu yodula ≥ 15 MPa).
Pa mapulatifomu olemera, kuyika kumafuna kukonzekera kwapadera kwa nthaka. Maziko a konkriti ayenera kukhala ndi makulidwe osachepera 300mm, ndi mbale zachitsulo zomangidwa kuchokera ku Q235. Pakati pa maziko ndi nsanja, gawo la rabara la chloroprene lokhala ndi makulidwe a 3mm limagwiritsidwa ntchito kuti zitsimikizire kufalikira kofanana kwa kupsinjika. Maziko ayenera kukhala ndi mphamvu yonyamula katundu ya osachepera 0.3 MPa. Mapulatifomu awa amagwiritsidwa ntchito poyang'anira zida zolemera zamakina ndi kapangidwe kake ka casting, komwe kusintha kwa nthawi yayitali kuyenera kukhala pansi pa 0.002mm pachaka.
Miyezo yoyesera ya mapulatifomu osiyanasiyana a granite okhala ndi katundu imasiyananso kwambiri. Mapulatifomu opepuka amayesedwa kugwedezeka (10-500Hz sweep frequency, amplitude 0.1mm) kuti atsimikizire kuti palibe resonance yomwe imachitika. Mapulatifomu apakati amayesedwa ku static load test ya 1.2 nthawi ya mphamvu yawo yoyesedwa, ndi kusintha kosapitirira 0.001mm pambuyo pa maola 24 ogwiritsidwa ntchito ndi kuchotsedwa kwa katundu. Mapulatifomu olemera amayesedwa kuti awone ngati ali ndi kutopa, ndi ma cycle 1000 otsitsa katundu pa 80% ya katundu wawo woyesedwa kuti atsimikizire kuti palibe ming'alu yomwe ikuwoneka, yotsimikiziridwa kudzera mu kuzindikira zolakwika zolowera.
Posankha nsanja yoyenera ya granite, ndikofunikira kuti kapangidwe kake kagwirizane ndi zofunikira za pulogalamuyo. Kwa mafakitale omwe amafunikira kulondola kwambiri komanso mphamvu zolemetsa katundu wolemera, kusankha kapangidwe koyenera ka nsanjayo kumatsimikizira kuti ikugwira ntchito bwino komanso kudalirika kwa nthawi yayitali. ZHHIMG imamvetsetsa kufunika kwa mayankho opangidwa mwapadera omwe amapangidwira zosowa zapadera za kasitomala aliyense, popereka nsanja zosiyanasiyana za granite zomwe zimapereka kulondola kwapamwamba, kukhazikika, komanso kulimba pansi pa mikhalidwe yosiyanasiyana yolemetsa.
Ku ZHHIMG, timapereka nsanja zambiri za granite, zopangidwa kuti zikwaniritse zosowa za mafakitale kuyambira pakupanga zinthu molondola mpaka kuwunika zinthu zolemera. Nsanja zathu zimapangidwa ndi miyezo yapamwamba kwambiri kuti zitsimikizire kuti zikugwira ntchito bwino kwambiri, zomwe zimapereka kulondola komanso kudalirika, mosasamala kanthu za zofunikira zonyamula katundu. Kudzipereka kwathu ku zatsopano ndi khalidwe labwino kumatithandiza kupereka mayankho omwe amatha nthawi yayitali, kukupatsani maziko abwino kwambiri pazosowa zanu zopangira zinthu molondola.
