Sechishandiso chakakosha chekutarisa munzvimbo dzekuyera nemazvo, kuramba kupfeka kwemagranite slabs kunosarudza zvakananga hupenyu hwebasa rawo, kururama kwekuyera, uye kugadzikana kwenguva refu. Izvi zvinotevera zvinotsanangura zvakarongeka pfungwa huru dzekudzivirira kwavo kupfeka kubva pamaonero ehunhu hwezvinhu, mashandiro ekupfeka, zvakanakira mashandiro, zvinhu zvinopesvedzera, uye nzira dzekugadzirisa.
1. Zvimiro zveZvinhu uye Nheyo dzeKuramba Kupfeka
Kuoma Kwakanaka uye Maumbirwo Akakora
Magranite slabs anonyanya kuumbwa nepyroxene, plagioclase, uye biotite shoma. Nekukwegura kwenguva refu, anokura chimiro chakatsetseka, achiwana kuomarara kweMohs kwe6-7, kuomarara kweShore kunodarika HS70, uye simba rekumanikidza re2290-3750 kg/cm².
Magadzirirwo aya akakora (kunyudzwa kwemvura <0.25%) anoita kuti pave nekusimba pakati petsanga, zvichikonzera kuramba kukwenya pamusoro zvakanyanya kupfuura simbi yakakandwa (iyo ine kuomarara kweHRC 30-40 chete).
Kukwegura Kwechisikigo uye Kusunungurwa Kwekushushikana Kwemukati
Matombo egranite anotorwa kubva mumatombo epasi pevhu emhando yepamusoro. Mushure memamiriyoni emakore ekukwegura kwechisikigo, zvese zvinonetsa mukati zvakaburitswa, zvichikonzera makristaro akakora, akakora uye magadzirirwo akafanana. Kugadzikana uku kunoita kuti isanyanya kukanganiswa nema microcracks kana deformation nekuda kwekuchinja-chinja kwekushushikana panguva yekushandiswa kwenguva refu, nokudaro ichiramba ichidzivirira kupera kwayo nekufamba kwenguva.
II. Maitiro Ekushanda Kwemapfekero Uye Kushanda Kwawo
Mafomu Ekushandisa Zvipfeko Zvikuru
Kuchekwa Kwesimbi: Kucheka-cheka kunokonzerwa nezvidimbu zvakaoma zvinotsvedza kana kutenderera pamusoro. Kuomarara kwakanyanya kwegranite (kwakaenzana neHRC > 51) kunoita kuti irambe yakasimba nezvidimbu zvinokwenya kupfuura simbi yakaumbwa, zvichideredza zvikuru kudzika kwemavanga pamusoro.
Kupfeka Zvinonamira: Kutamiswa kwezvinhu kunoitika pakati penzvimbo dzinosangana nesimbi pasi pekumanikidzwa kwakanyanya. Hunhu hweGranite husina simbi (kusachinja-chinja kwemagineti uye kusachinja-chinja kwepurasitiki) hunodzivirira kunamira kwesimbi kubva kusimbi kuenda kusimbi, zvichikonzera kusakara kwesimbi kusvika pazero.
Kupera Kuneta: Kubviswa kweganda pamusoro kunokonzerwa nekumanikidzwa kwemuchina. Granite's high elastic modulus (1.3-1.5×10⁶kg/cm²) uye mvura shoma inonyudzwa (<0.13%) zvinopa simba rakanaka rekudzivirira kuneta, zvichibvumira kuti pamusoro payo parambe paine girazi rakapenya kunyangwe mushure mekushandiswa kwenguva refu.
Ruzivo Rwakajairika rweKushanda
Miedzo inoratidza kuti magranite slabs anowana 1/5-1/3 chete yekusakara kwema cast iron slabs pasi pemamiriro akafanana ekushanda.
Kukosha kweRa pamusoro kunoramba kwakasimba mukati mehuwandu hwe0.05-0.1μm kwenguva yakareba, zvichisangana nezvinodiwa zveKirasi 000 (kushivirira kwekutsetseka ≤ 1×(1+d/1000)μm, uko d iri kureba kwedhayagiramu).
III. Mabhenefiti Akakosha Ekuramba Kupfeka
Kukwiza Kwemafuta Kwakaderera uye Kuzvizora Kwega
Pamusoro peGranite pakapfava, paine kukweshana kwe0.1-0.15 chete, hazvipi simba rakawanda kana maturusi ekuyera achitsvedza pamusoro payo, zvichideredza kupera simba.
Kusava nemafuta kweGranite kunoita kuti ibvise kusakara kunokonzerwa neguruva rinonyungudutswa nemafuta, zvichikonzera kuti mari yekugadzirisa iderere zvakanyanya pane masimbi akaumbwa (anoda kuti mafuta anodzivirira ngura ashandiswe nguva dzose).
Haigoni Kubatwa neKuora neMakemikari
Kushanda zvakanaka kwazvo (hapana ngura iri pakati pe pH 0-14), yakakodzera kushandiswa munzvimbo dzine hunyoro uye makemikari.
Hunhu hunodzivirira ngura hunobvisa kupwanyika kwenzvimbo kunokonzerwa nengura yesimbi, zvichikonzera kuchinja kwehurefu hwe<0.005mm pagore mushure mekushandiswa kwenguva refu.
IV. Zvinhu Zvikuru Zvinokanganisa Kusapfeka
Kupisa uye Hunyoro
Kuchinja-chinja kwetembiricha (>±5°C) kunogona kukonzera kuwedzera kwekupisa uye kudzikira, zvichikonzera kutsemuka kwezvidimbu. Nzvimbo inokurudzirwa yekushanda itembiricha inodzorwa ye20±2°C uye hunyoro hwe40-60%.
Hunyoro hwakanyanya (>70%) hunoita kuti hunyoro hupinde nekukurumidza. Kunyangwe granite isingapindi mvura zvakanyanya, kugara kwenguva refu mumvura kunogona kuderedza kuomarara kwenzvimbo yacho.
Mutoro uye Kushungurudzika Kwekubatana
Kupfuura mutoro wakayerwa (kazhinji chikamu chimwe mugumi chesimba rekumanikidza) kunogona kukonzera kupwanywa kwenzvimbo. Semuenzaniso, imwe modhi yegranite slab ine mutoro wakayerwa we500kg/cm². Pakushandiswa chaiko, mutoro wekukurumidza wekukuvara unodarika kukosha uku unofanirwa kudzivirirwa.
Kupararira kwesimba rekubata zvinhu zvisina kuenzana kunokurumidza kupera. Rutsigiro rwemapoinzi matatu kana dhizaini yemutoro wakapararira zvakaenzana inokurudzirwa.
Kugadzirisa uye Kuchenesa
Usashandise mabhurashi esimbi kana zvishandiso zvakaoma pakuchenesa. Shandisa jira risina guruva rakanyoroveswa ne isopropyl alcohol kuti usakwenya pamusoro.
Gara uchitarisa kuomarara kwenzvimbo. Kana kukosha kweRa kuchidarika 0.2μm, gadzirazve uye gadzirisa.
V. Nzira dzekugadzirisa nekuvandudza kusapfeka
Kushandisa Nekuchengetedza Zvakakodzera
Dzivisa kudonha kwakanyanya kana kudonha. Simba rekudonha rinodarika 10J rinogona kukonzera kurasikirwa kwezviyo.
Shandisa chinhu chinotsigira panguva yekuchengetera uye fukidza pamusoro nefirimu rinodzivirira guruva kudzivirira guruva kuti risapinde muma micropores.
Ita Kuongororwa Kwakajairwa Kwemazvo
Tarisa kuti mutsetse wacho wakadzikama here uchishandisa electronic level mwedzi mitanhatu yega yega. Kana chikanganiso chikadarika mwero wekutsungirira (semuenzaniso, chikanganiso chinobvumirwa cheplate ye00-grade i≤2×(1+d/1000)μm), dzosera kufekitori kuti ugadziriswe zvakanaka.
Isa wakisi inodzivirira usati waichengeta kwenguva yakareba kuderedza ngura munzvimbo.
Matekiniki Ekugadzirisa uye Kugadzira Patsva
Kupera kweganda <0.1mm kunogona kugadziriswa munzvimbo iyoyo nedhaimani rinonamira kuti ridzorere girazi reRa ≤0.1μm.
Kupera kwakadzika (>0.3mm) kunoda kudzoserwa kufekitori kuti igokwezve, asi izvi zvinoderedza ukobvu hwese hweplate (daro rekukuya rimwe chete ≤0.5mm).
Kusapera kwegranite slabs kunobva pakubatana pakati pehunhu hwayo hwechisikigo hwezvicherwa uye mashandiro akarurama. Nekugadzirisa nzvimbo yekushandisa, kugadzirisa maitiro ekugadzirisa uye kushandisa tekinoroji yekugadzirisa, inogona kuramba ichiratidza zvakanakira zvayo zvekururama kwakanaka uye kugara kwenguva refu munzvimbo yekuyera kwakarurama, ichiva chishandiso chekuenzanisa mukugadzira maindasitiri.
