Sechishandiso chakakosha chereferensi munzvimbo dzekuyera chaiko, magranite slabs 'kupfeka kuramba kunotarisisa hupenyu hwavo hwesevhisi, kuyerwa kwechiyero, uye kugadzikana kwenguva refu. Izvi zvinotevera zvakarongeka zvinotsanangura mapiinzi akakosha ekuramba kwavo kupfeka kubva pamaonero ezvivakwa zvenyama, zvigadziriso zvekupfeka, mabhenefiti ekuita, zvinofurira zvinhu, uye maitiro ekugadzirisa.
1. Material Properties uye Wear Resistance Basics
Yakanaka Kuoma uye Dense Chimiro
Granite slabs inonyanya kuumbwa nepyroxene, plagioclase, uye shoma shoma yebiotite. Kuburikidza nekuchembera kwenguva refu kwechisikigo, vanogadzira chimiro-chakanaka, kuwana kuomarara kweMohs kwe6-7, kuomarara kweShore kunodarika HS70, uye simba rekumanikidza re2290-3750 kg/cm².
Iyi dense microstructure (kunyura kwemvura <0.25%) inovimbisa kusungirirwa kwakasimba kwepakati-zviyo, zvichikonzera kuramba kwepamusoro kwepamusoro zvakanyanya kudarika iron yakakandwa (iyo ine kuoma kweHRC 30-40 chete).
Kuchembera Kwepanyama uye Kushushikana Kwemukati Kuburitswa
Granite slabs inotorwa kubva pamhando yepamusoro yepasi pevhu matombo. Mushure memamiriyoni emakore ekuchembera kwechisikigo, kushushikana kwemukati mese kwakaburitswa, zvichikonzera makristasi akaomesesa, akaomeswa uye yunifomu yemavara. Uku kugadzikana kunoita kuti isanyanya kubatwa ne microcracks kana deformation nekuda kwekushushikana kushanduka panguva yekushandiswa kwenguva refu, nekudaro ichichengetedza kupfeka kwayo kuramba nekufamba kwenguva.
II. Pfeka Mechanisms uye Performance
Main Wear Forms
Abrasive Wear: Micro-kucheka kunokonzerwa nezvidimbu zvakaoma zvinotsvedza kana kukunguruka pamusoro. Granite yakanyanya kuomarara (yakaenzana neHRC> 51) inoita kuti ive 2-3 nguva inopesana neabrasive particles pane simbi yakakandwa, zvakanyanya kuderedza kudzika kwekukwenya kwepamusoro.
Adhesive Wear: Kufambiswa kwezvinhu kunoitika pakati penzvimbo dzekusangana pasi pekumanikidzwa kwakanyanya. Granite's non-metallic properties (isina-magnetic uye isiri-plastiki deformation) inodzivirira simbi-ku-metal adhesion, zvichiita kuti pave pedyo-zero kupfeka mwero.
Kuneta Kupfeka: Kupeuka kwepamusoro kunokonzerwa necyclic stress. Granite's high elastic modulus (1.3-1.5 × 10⁶kg/cm²) uye kunyura kwemvura yakaderera (<0.13%) kunopa kwakanakisa kuneta kuramba, zvichibvumira pasi kuchengetedza girazi-kunge gloss kunyangwe mushure mekushandisa kwenguva refu.
Typical Performance Data
Miedzo inoratidza kuti granite slabs inosangana chete ne1 / 5-1 / 3 kupfeka kwesimbi yakakandwa pasi pemamiriro akafanana ekushanda.
The pamusoro roughness Ra kukosha inoramba yakagadzikana mukati 0.05-0.1μm kureba kwenguva refu, kusangana Class 000 zvakarurama zvinodiwa (flatness kushivirira ≤ 1 × (1+d/1000) μm, apo d ari diagonal kureba).
III. Yakakosha Yakanakira Wear Resistance
Yakaderera Friction Coefficient uye Self-Lubrication
Granite yakatsetseka yepasi, ine coefficient yekukwesha kwe 0.1-0.15 chete, inopa kushomeka kwekupokana kana maturusi ekuyeresa achitsvedza pairi, achidzikisa mapfekero.
Hunhu husina mafuta hweGranite hunobvisa kusapfeka kwechipiri kunokonzerwa neguruva rinoshambadzirwa nemafuta, zvichikonzera kuderera kwakanyanya kwemitengo yekugadzirisa pane kukanda simbi slabs (inoda kugara uchiiswa mafuta anorwisa ngura).
Inopikisa Chemical Corrosion uye Ngura
Kuita kwakanakisa (hapana ngura mukati mehupamhi hwepH ye0-14), yakakodzera kushandiswa munzvimbo dzakanyorova uye dzemakemikari.
Zvinhu zvinodzivirira ngura zvinobvisa kukoromoka kwepasi kunokonzerwa nekuora kwesimbi, zvichikonzera shanduko yeflatness ye <0.005mm/gore mushure mekushandiswa kwenguva refu.
IV. Zvinhu Zvikuru Zvinokanganisa Wear Resistance
Ambient Temperature uye Humidity
Kuchinja kwekushisa (> ± 5 ° C) kunogona kukonzera kuwedzera kwekupisa uye kuderera, zvichiita kuti microcracks. Nzvimbo yekushanda yakakurudzirwa inodzorwa tembiricha ye20±2°C uye mwando we40-60%.
Hunyoro hwepamusoro (> 70%) hunomhanyisa kupinda kwehunyoro. Kunyange zvazvo granite ine mwero wakaderera wekutora mvura, kuratidzwa kwenguva refu kune hunyoro kunogona kuramba kudzikisa kuoma kwepasi.
Rodha uye Bata Stress
Kupfuura mutoro wakayerwa (kazhinji 1/10 yesimba rekumanikidza) kunogona kukonzera kudzvanywa kwenzvimbo. Semuenzaniso, imwe modhi yegranite slab ine chiyero chakayerwa che500kg/cm². Mukushandiswa chaiko, mitoro yenguva pfupi inodarika iyi kukosha inofanira kudzivirirwa.
Uneven contact stress distribution inomhanyisa kupfeka. Tsigiro yemapoinzi matatu kana dhizaini yakagovaniswa yakaenzana inokurudzirwa.
Kuchengetedza uye Kuchenesa
Usashandise mabhurashi esimbi kana midziyo yakaoma paunenge uchichenesa. Shandisa jira risina guruva rakanyoroveswa ne isopropyl doro kudzivirira kukwenya pamusoro.
Gara uchitarisa kushata kwepamusoro. Kana iyo Ra kukosha ichipfuura 0.2μm, regrind uye kugadzirisa kunodiwa.
V. Maintenance and Improvement Strategies for Wear Resistance
Kushandiswa Kwakakodzera uye Kuchengeta
Dzivisa zvinorema zvinokanganisa kana madonhwe. Impact simba rinopfuura 10J rinogona kukonzera kurasikirwa kwezviyo.
Shandisa tsigiro panguva yekuchengetera uye kufukidza pamusoro neguruva-proof firimu kudzivirira guruva kubva mukunyura mumamicropores.
Ita Regular Precision Calibration
Tarisa kupfava nechiyero chemagetsi mwedzi mitanhatu yega yega. Kana kukanganisa kwakapfuura chiyero chekutsungirira (semuenzaniso, kukanganisa kunobvumirwa kwendiro yegiredhi 00 iri ≤2×(1+d/1000)μm), dzokera kufekitari kuti ugadzirise zvakanaka.
Isa wakisi inodzivirira usati wachengeta kwenguva refu kuti uderedze ngura kwezvakatipoteredza.
Kugadzirisa uye Kugadzira Patsva Techniques
Kupfeka kwepamusoro <0.1mm kunogona kugadziriswa munharaunda nedhaimani abrasive paste kudzoreredza girazi kupera kweRa ≤0.1μm.
Kupfeka kwakadzika (> 0.3mm) kunoda kudzokera kufekitari kuti igayezve, asi izvi zvinoderedza kukora kweplate (imwe yekukuya kure ≤0.5mm).
Kuramba kwekupfeka kwegranite slabs kunobva mukuwirirana pakati pezvawo zvechisikigo zvicherwa zvimiro uye kunyatsogadzira machining. Nekugadzirisa nharaunda yekushandisa, kuenzanisa maitiro ekugadzirisa uye kutora tekinoroji yekugadzirisa, inogona kuenderera mberi ichiratidza zvakanakira kurongeka kwakanaka uye hupenyu hurefu munzvimbo yekuyera chaiyo, ichiva bhenji chishandiso mukugadzira maindasitiri.
