Tsvagiridzo pamusoro peKupesvedzera kweBrown Fused Alumina Micropowder paKuoma kweNzvimbo
Mubasa redu, kunyanya mukugadzirisa pamusoro kana kugadzirisa zvinhu, tinotarisa chiratidzo che "kuomarara" anenge mazuva ese. Zvakafanana ne "minwe" yezvinhu, zvichiratidza zvakananga kana chifukidziro chinotevera chinogona kunamira, kuti zvikamu zvinoramba kupera, uye kunyange mhedzisiro yekuvhara kwechikamu. Nhasi, ngatiregei kutaura nezvedzidziso idzodzo dzepamusoro-soro, asi garai pasi totaura sevashandi pamwe chete nezveshamwari yedu yekare yatinozivikanwa zvikuru - brown fused alumina micropowder - uye kuti "inodzora" sei kuomarara pamusoro pezvinhu.
I. Kutanga, ngatinzwisisei: Chii chinonzi brown fused alumina micropowder?
Alumina yakasanganiswa yebrown, muchidimbu, ndizvo zvatino "natsa" tichishandisa zvinhu zvakaita sealumina necoke muchoto chemagetsi. Nekuti ine mamwe matitanium ne iron oxides, ine ruvara rwebrownish, ndosaka ichinzi. Ine kuomarara kwakanyanya, kuomarara kwakanaka, uye inodhura zvishoma, zvichiita kuti ive "chinhu chikuru" mukugadzira nekugadzira jecha.
Uye izwi rekuti "micropowder" ndiro rinokosha. Rinoreva upfu hwakatsetseka hunowanikwa nekupwanya nekusefa alumina yakasanganiswa nebrown kuburikidza nenzira yakakosha, ine saizi yezvikamu zvinowanzo bva pamazana kusvika kuzviuru zvemameshe. Musarerutsa upfu uhwu; hausisiri "banga rekutema huni," asi "banga rekuveza" rakakodzera. Kubuda kwahwo kwakabvumira alumina yakasanganiswa nebrown kuti ibve pamabasa akaoma sekubvisa ganda rakakora kubva muzvinhu zvinogadzirwa nesimbi kuenda kunzvimbo yekugadzira nemazvo, uko kunodiwa mhando yepamusoro yepamusoro.
II. "Inoveza" Sei Pamusoro? - Nyika Inoshamisa yeMicroscopic
Vanhu vazhinji vanofunga kuti kuputira jecha kungorova pamusoro pejecha, uye kana ukanyanya kuomesa, ndipo panonyanya kuomarara. Izvozvo ndezvechokwadi, asi kune isu vanodzidza nezvema micro-powders, imwe hafu ndiyo inonyanya kukosha. Simba re brown fused alumina micro-powder pakukwirira kwenzvimbo ibasa rakaoma, randinopfupikisa kuita mhedzisiro mitatu mikuru:
"Kuchera" (Kucheka Kukuru): Uku ndiko kunonyanya kunzwisisika. Zvidimbu zveupfu hudiki zvinobhururuka nekukurumidza, senyundo diki dzisingaverengeki nemachisel, zvinokanganisa pamusoro pechinhu. Zvidimbu zvakaoma "zvinoruma" zvakananga pachinhu chacho, zvichiita makomba madiki. Danho iri ndiro guru rinoita kuti pave nekukombama kwepamusoro-soro. Fungidzira nzvimbo yakatsetseka ichibviswa nemakomba madiki asingaverengeki; musiyano uripo pakati pemakomo nemapani unowedzera zvakanyanya, zvichiwedzera kukosha kwekukombama (semuenzaniso, Ra, Rz).
"Kurima" (kugadziriswa kwepurasitiki): Izvi zvinonakidza. Kana zvidimbu zvikasarova pamusoro zvakananga, asi "kukwesha" nepakona, zvinogona kusacheka zvakananga nechinhu chacho. Pane kudaro, sekurima, "zvinodzvanya" chinhu chacho kumativi, zvichiita "gomba" rakasimudzwa. Maitiro aya haabvisi chinhu zvakananga, asi kuburikidza nekugadziriswa kwepurasitiki, anochinja chimiro chepamusoro, zvichiwedzera musiyano uripo pakati pemakomo nemipata.
"Kudzvanya" uye "kuneta": Pasi pekudzvanya kunoramba kuripo kwetimbuyu tudiki, pamusoro pechinhu chinoitwa "kunatswa" kuburikidza nekudzvanya kunodzokororwa. Kudzvanya kwekutanga kunogona kusunungura pamusoro, asi kudzvanya kunoenderera mberi "kunodzvanya" pamusoro, zvichiita kuti pave nechikamu chakakora uye chakasimbiswa. Panguva imwe chete, kudzvanya kunodzokororwa kunokonzera kuneta muchimiro chechinhu, zvichiita kuti zvive nyore kuti timbuyu tunotevera tibvise.
Sezvamunoona, kunyangwe maitiro akareruka ekuputika kwejecha ane mhedzisiro nhatu panguva imwe chete uye dzinoshanda pamwe chete munyika isingaoneki nemaziso: "kuchera," "kurima," uye "kutambisa."
III. Zvinhu Zvitatu Zvikuru Zvinokanganisa Mhedzisiro: Saizi yeChidimbu, Kudzvanywa, uye Angle
Zvino zvatava kunzwisisa musimboti uyu, tinga "rayira" seiupfu hwebrown hwakasanganiswa hwealumina micropowderKuti uwane kuomarara kwepanzvimbo kunodiwa pakushanda chaiko? Zvinonyanya kuvimba nezvinhu zvitatu izvi zvakakosha:
Chinhu Chekutanga: Saizi yezvikamu (Hupfu hunofanira kunge hwakakora sei?)
Iyi ndiyo parameter inonyanya kukosha. Zvichitaurwa zviri nyore, mumamiriro ezvinhu akafanana, kana zvidimbu zvakakora, kukosha kwehupfu hwepamusoro kunowedzera. Kushandisa upfu hwakakora hwe80-mesh kuchaita kuti nzvimbo iite seyakakora zvikuru nekukasira; asi kana ukashandisa W40 kana hupfu hwakakora, nzvimbo yacho ichave yakatsetseka uye inonzwa zvakanaka. Izvi zvakafanana nekukwesha huni nesandpaper yakakora kana ukashandisa sandpaper yakakora—mhedzisiro yacho yakasiyana zvikuru. Saka, kuti uwane hupfu hwakakora, kusarudza hupfu hwakakora ndiyo danho rekutanga.
Chinhu chechipiri chakakosha: Kudzvanywa kwespray (Simba rakawanda sei?)
Kumanikidzwa isimba rinopihwa kuzvidimbu. Kumanikidzwa kukuru, zvidimbu zvinobhururuka nekukurumidza, simba rekufamba naro rinowedzera, uye simba re "kuchera" ne "kurima" rinowedzera simba, zvichikonzera kuomarara kukuru. Zvisinei, pane dambudziko: kumanikidzwa kwakanyanya hakusi nani nguva dzose. Kumanikidzwa kwakanyanya kunogona kutungamira mukuchekwa zvakanyanya, kutokuvadza kururama kwechikamu chebasa, kana kutotyora zvinhu zvisina kusimba. Ruzivo rwedu nderwekuti, paunenge uchizadzisa zvinodiwa zvekuchenesa nekuomarara, zvakanaka kushandisa kumanikidzwa kwakaderera—"shandisa simbi yakanakisa painokosha."
Chinhu chechitatu chakakosha: Kona yekupfapfaidza (Inobva kudivi ripi?)
Vanhu vazhinji vanofuratira parameter iyi. Tsvagiridzo inoratidza kuti kana kona yekupfapfaidza iri pakati pe70° ne90° (inenge yakatwasuka), kuwedzera kwekuomarara kwakakosha zvikuru nekuti mhedzisiro ye "kuchera" inonyanya kukosha. Kana kona ikava diki (semuenzaniso, 30°-45°), mhedzisiro ye "kurima" inova pachena, zvichikonzera chimiro chakasiyana chekuomarara. Kana tichida kuchenesa pamusoro asi tisingade kuti pave nekuomarara zvakanyanya, dzimwe nguva tinoshandisa kona diki kuti tiwane chiyero pakati pekuchenesa nekuomarara.
IV. "Zvakavanzika" uye Kufungisisa muKushanda Kwemashoko
Dzidziso chete haina kukwana; kune "zvakavanzika" zvakawanda zvinowanikwa mubasa chairo.
Semuenzaniso, "temperament" yechinhu chebasa (hunhu hwechigadzirwa chacho) kwakakosha. Kushandisa ma parameter akafanana pakugadzira simbi yakasimba uye yakapfava nearuminiyamu kuchapa mhedzisiro yakasiyana zvachose. Zvinhu zvakapfava zvinowanzo shanduka kuita purasitiki, zvichigadzira "migero" yakadzika uye yakafara uye inovharika nyore nyore; zvinhu zvakaoma zvinogona kupwanyika zvisina kusimba, zvichiita makomba akawanda.
Mumwe muenzaniso ndewe "hupenyu" hwe micro-powder.Upfu hudiki hwebrown hwakasanganiswa nealuminaichapera yopwanyika nekufamba kwenguva. Batch itsva yeupfu ine saizi yakaenzana yezvikamu, mipendero yakapinza, uye simba rekucheka rakasimba, zvichigadzira kuomarara kwakafanana uye kwakakura. Zvisinei, upfu hwakashandiswa, hune mipendero yakatenderera uye saizi diki yezvikamu, hunova "hwekare uye hwasakara," nesimba rekucheka rakaderera, zvichigona kugadzira kuomarara kudiki uye kwakafanana, kwakakodzera kupedzisa "satin" pamusoro nguva dzose. Zvese zvinoenderana nezvinodiwa nemaitiro ako.
Nokudaro, kudzidza mhedzisiro yeupfu hwebrown hwakasanganiswa hwealumina microKuomarara pamusoro pechinhu hakusi kungotarisa zvinhu zvacho nekushanda zvinoenderana nazvo. Inyanzvi yekudzora zvinhu nemazvo munyika isingaoneki. Tinofanira kuita sechiremba wemishonga yechivanhu wechiChinese ane ruzivo, tichiziva neunyanzvi hunhu nenzira dze "mishonga yemishonga" yakaita se "tindindi, kumanikidzwa, uye kona," tobva tabatanidza izvi ne "bumbiro" rechinhu chebasa, kuitira kuti tipe "mushonga" unoshanda zvakanyanya uye tiwane kuomarara kwepamusoro kwakakwana.
