Kushanda Kwazvo KweWhite Corundum Micropowder Mukugadzira Matombo
Kutaura chokwadi, kana zvasvika pa "kupukuta matombo," pfungwa yekutanga yevanhu vazhinji ingave michina mikuru, mafekitori ane ruzha, uye madhisiki ekukuya ari mumaoko evagadziri vane ruzivo. Asi kana uchinyatsonzwisisa indasitiri iyi, uchaona kuti kazhinji ma micropowders asingaonekwe ndiwo anonyatso sarudza mhedzisiro yekupedzisira. Semuenzaniso,upfu hwe corundum chenaTiri kukurukura nhasi kuti iyi "nyanzvi yekupukuta" yakavanzwa kuseri kwezviitiko. Pandakatanga kushanda mubasa iri, ndakashamisikawo: Hazvisi kungopukuta matombo chete here? Chero "upfu" hauna basa. Asi mushure mekuona zvakawanda, ndakaona kuti kusarudza micropowder chaiyo kunogona kuita mutsauko mukuru mumhedzisiro.
1. Chii chinonzi white corundum micropowder? Sei yakakodzera kupolisha?
White corundum, kutaura zviri nyore, chinhu chakagadzirwa nevanhu, chakachena zvikuruaruminiyamu oxide (Al₂O₃). Yakaoma kupfuura corundum yechisikigo, ine kuomarara kweMohs kwe9.0, yechipiri kune dhaimani nesilicon carbide. Sezvinoreva zita racho, "micropowder" zvinoreva chinhu chakapwanywa ndokuseferwa kuita upfu hwakatsetseka hwe micron-level. Ungabvunza kuti: "Chinhu ichi hachizokwenyi dombo here?" Izvi zvinotisvitsa kune zvakanakira: kuomarara kwakanyanya asi kuomarara kwakanaka: zvidimbu zvichena zve corundum hazvipindi pakutyoka, zvichichengetedza simba rekucheka rakafanana panguva yekukwesha; kugadzikana kwemakemikari: hazvisangani nemaminerari ari mudombo, zvichikonzera kusachinja kweruvara kana ngura; uye saizi yezvidimbu inodzorwa zvakanyanya: inopa basa rakakwana kubva pakukuya kusvika pakukwesha zvakanaka, zvichiita kuti zvive zvakakodzera kune maitiro ekukwesha akawanda. Hunhu uhwu hunoita kuti ive yakakodzera zvakanyanya kugadzirisa matombo ekushongedza akafanana semarble, granite, uye dombo rekugadzira.
II. Chii chinoita kuti ive "inoshanda zvakanaka" pakupukuta chaiko?
Vanhu vazhinji vanofunga kuti kupukuta kunongoreva kupedzisa dombo zvakanaka, asi handizvo zvazviri. Maitiro akanaka ekupukuta anofanira kubvisa mavanga nekukurumidza uku uchivandudza kupenya zvishoma nezvishoma, ukuwo uchidzivirira kupukuta zvakanyanya kana kukuvadza tsanga.
1. Kukwesha kwakakora, kwepakati, uye kwakanaka, kwapera zvakanaka
Semuenzaniso, pakushanda nematombo emarble pasi:
Kupukuta zvisina kunaka (80#-200#): Shandisa chinhu chakakoraupfu hwecorundum chena(senge W40-W20) kuti ikurumidze kupfavisa pamusoro uye kubvisa mavanga akadzika;
Kupukuta kwepakati (400#-800#): Chinja upfu hwakatsetseka (senge W14-W7) kuti utange kupukuta;
Kupukuta zvakanaka (1500#-3000#): Hupfu hwakafanana neW3.5 kana pasi hunogona kushandiswa kuita kuti hupedzisire hwakaita segirazi.
Uchaona kuti hupfu hwezvinhu zvakafanana, muhukuru hwakasiyana-siyana hwezvimedu, hunogona kushandiswa munguva yese yekupukuta, zvichibvisa kudiwa kwekuchinja zvinhu kakawanda—kuchengetedza nguva, kushanda nesimba, uye zvikanganiso.
2. Kunamatira kwakasimba uye kupenya nekukurumidza
Zvichienzaniswa nezvinhu zvechinyakare zvakaita sevhu rediatomaceous necerium oxide, upfu hwecorundum chena, hune zvidimbu zvahwo zvakapinza (panzvimbo pedenderedzwa), hunonyanya kunyudzwa pamusoro pedombo, zvichikonzera kushanda zvakanaka kwekucheka. Taenzanisa: kupukuta chidimbu chimwe chete chegranite necorundum micropowder chena kunogona kuwana kupenya kwakafanana munguva 1/3 shoma pane kupukuta nezvinhu zvakajairwa.
3. Haasarudze matombo, anoshandiswa zvakasiyana-siyana
Corundum chenaInonyanya kushandiswa nevanhu vose, ingave marble ine acid yakawanda kana granite ine silica yakawanda. Izvi zvinonyanya kuitika kumatombo ekugadzira akasanganiswa (akadai se quartz), ane resin uye mineral. Mazhinji mabrasives echinyakare anogona kuita kuti ive isina kusimba kana kuti isina kujeka, nepo corundum chena ichigara ichipa kupenya.
4. Nguva refu yehupenyu uye mutengo wakaderera
Kunyange zvazvo upfu hwe white corundum micropowder hungave hwakanyanya kudhura pane zvimwe zvinhu zvechinyakare, hahutsvuki, hahuna kusimba, uye hunogona kushandiswazve zvakanyanya. Kazhinji, boka rezvinhu rinogona kufukidza nzvimbo yakakura ye20%-30%, zvichiita kuti rive rakanaka kwenguva refu.
Ⅲ. Pane mienzaniso chaiyo here? Inoshanda zvechokwadi here?
Regai ndikupei muenzaniso wangu: Gore rapera, imba yekutandarira yehotera yakagadziriswazve. Pasi pemabhuru e beige pakanga pakafukidzwa nemavanga kubva mumakore ekushandiswa uye pakanga paine kupenya kuri pasi pe30. Chikwata chekuvaka pakutanga chakashandisa upfu hwekupukuta hwakajairika, asi mushure memajasi matatu, mhedzisiro yacho yakanga ichiri isingagutsi. Vakazochinja kuita kupukuta kwakavakirwa pa white corundum micropowder. Mushure memajasi maviri chete, vakawana kupenya kuri pamusoro pemadhigirii makumi manomwe nemashanu. Kupenya kwekupedzisira pakutumira kwaive pedyo ne85. Mutengi akabva angovandudza chibvumirano. Nyanzvi yemhizha yakataura chimwe chinhu chinobva pamwoyo: "Chinhu ichi chakafanana nekuwana chombo chitsva mumutambo—chinouraya zvikara nekukurumidza uye hachikubhadharisi mari yakawanda."
IV. Mafambiro Ebudiriro Yeramangwana? Achatsiviwa Here?
Parizvino, upfu hwe corundum chena hunoramba hwakasimba mukukwesha matombo, asi huri kuchinjawo:
Saizi yezvikamu zvakapfava uye zvakapfava: Upfu hwe corundum chena hwemhando ye Nano-grade (semuenzaniso, W1.0 uye pazasi) hwatanga kushandiswa pakupukuta magirazi epamusoro, kunyanya mukushongedza kwepamusoro-soro uye kugadzira matombo ehunyanzvi;
Mashandisirwo akabatanidzwa: Semuenzaniso, kana ikasanganiswa necerium oxide nedhaimani powder, inoita kuti icheke zvakanaka uye iwedzere kupenya, yakakodzera matombo chaiwo;
Kuchengetedzwa kwezvakatipoteredza kwakawedzerwa uye kuchengetedzeka: Chizvarwa chitsva chemvura inotonhorera chiri kutsiva hupfu hwekare hwakaoma zvishoma nezvishoma, zvichideredza kusvibiswa kweguruva uye zvichiita kuti zvive zvakakodzera kushandiswa kwekugadzira otomatiki;
Mhedziso: Zvishandiso Zvidiki, Kukanganisa Kukuru
Kazhinji, tinonyanya kutarisa pane zviri pachena—semhando yemuchina wekupolisha kana mukurumbira wechikwata chekuvaka—asi tinokanganwa zvinhu zvinonyatsokanganisa mhedzisiro yacho.Upfu hwecorundum chena chinhu "chisina musoro, asi chakakosha". Kana uri kugadzirisa imba yako kana kushanda muindasitiri yekuchengetedza matombo, nguva inotevera yaunobatanidzwa mukuita kwekupukuta, ungabvunza mumwe mubvunzo: "Ndeipi mhando yeupfu hudiki hwatiri kushandisa?" Mhedzisiro yekupedzisira inogona kunge yakasiyana zvachose nekuda kwemubvunzo uyu.
