Green Silicon Carbide Micropowder: Simba rekuvandudza mashandiro emaIndustrial Coatings
Nhasi, ngatikurukurei pachedu nezvechinoita kuti iyi green silicon carbide micropowder ive yakakosha.
I. Kutanga, ngatinzwisisei kuti iyi "green silicon carbide" chii.
Kana uchinzwa zita iri kekutanga, rinonzwika se "makemikari" uye repamusoro-soro. Asi zvechokwadi, rakafanana nehama yealumina chena yakasanganiswa yatakambotaura nezvayo kare—ose ari maviri ndeemhuri yezvinhu zvakaoma kwazvo.
Kugadzirwa kwayo kwakafanana nekugadzira simbi: zvinhu zvakaita sejecha re quartz ne petroleum coke zvinokandwa muchoto chemagetsi uye "zvinonatswa" patembiricha inodarika 2000 degrees Celsius. Nekuti ine zvinhu zvakati wandei, inopenya kuita ruvara urwu rwegirini rwakasiyana, ndosaka zita rekuti "green silicon carbide."
Hunhu hwayo hukuru hunosvika pamashoko maviri: hwakaoma uye hwakapinza.
Yakaoma sei? Pachikero cheMohs, inomira pa9.2–9.5! Izvi zvinorevei? Yakafanana nedhaimani (10) uye inodarika simbi dzakajairika, girazi, uye marble pakuoma kwayo. Uyezve, zvidimbu zvayo zvine mipendero yakapinza nemakona, kusiyana nemamwe mabhora akatenderera akatsetseka uye akatenderera.
Fungidzira semabhiriyoni e "mafaira edhaimani" madiki, akaomarara. Kune isu tiri muindasitiri yekupenda, kuiwedzera pakupenda kwakafanana nekupa kupendesa jira risingaonekwe re "cheni yezvombo zvesimbi".
II. Zvinonyatsoita sei kuti "zviwedzere" machira ekuputira?
Kungotaura nezvekuoma kwayo hakunyatsooneki. Kukosha kwayo kwechokwadi kuri mukuvandudza mashandiro ekuputira—ndipo panoitika mashiripiti chaiwo.
Chekutanga uye chinonyanya kukosha—hunyanzvi hwayo—kuramba kukwenya nekukwenya.
Izvi zviri nyore kunzwisisa. Fungidzira pamusoro pechifukidziro chako chakafukidzwa nezvidimbu zvakawanda zvakaoma, zvakapinza serezor. Kana chimwe chinhu chikakwenya kana kukuya, nzvimbo idzi dzakaoma dzinoumba "mutsara wekutanga wekudzivirira." Masimba ekunze anofanira kutanga aakunda asati asvika pasi pe resin yakapfava iri pasi.
Zvakafanana nekufamba pamusoro pevhu rakapfava—nhanho imwe neimwe inosiya tsoka yakadzika. Asi munzira yakagadzirwa nematombo akaomarara, hapana kana chiratidzo chaunowana. Miedzo yedu inoratidza kuti machira epasi epoxy ane fomura imwechete asi achisanganisira huwandu hwakakwana hwe silicon carbide micropowder anogona kuwedzera kaviri kana katatu hupenyu hwawo kana akaedzwa ne abrasion tester! Kune nzvimbo dzakadai semafekitori, nzvimbo dzekupaka mota, uye matura makuru, mashandiro aya akakosha zvikuru.
Chimwe chekubatsira ndechekunamira kwakawedzerwa, zvichiita kuti chifukidziro chikwanise "kubata" zvakasimba.
Kubatsira uku kunogona kushamisa vanhu vari kunze. Upfu uhu hahungoyangarari pasi peganda chete—hunoumba chimiro che "anchor chain" chisingaoneki. Kune rumwe rutivi, nzvimbo dzahwo dzakaoma dzinobatana zvakanaka neresin. Kune rumwe rutivi, kana dzikashandiswa pazvinhu zvakaita sesimbi kana kongiri, uhu hupfu hwakaoma hunopinda muzvinhu zvisingaonekwe zvakanaka, zvichigadzira simba guru rekubatanidza michina.
Zvichitaurwa zviri nyore: machira akajairwa akafanana nekuisa guruu kuti ubatanidze bepa rakatsetseka pamadziro. Machira ane silicon carbide yegirini, zvisinei, akafanana nekutanga aita kuti madziro anyatsokweshana, wozoabatanidza nezvisungo zvehook-and-loop. Kubatana kwacho hakuna muenzaniso. Izvi zvakakosha kudzivirira kuti machira arege kukweshana uye kutsemuka.
Kubatsira kwechitatu: Kudzivirira kutsvedza kwakanyanya, zvichiisa kuchengetedzeka pakutanga.
Ingava pasi pefekitori, madhiki engarava, kana mabhiriji evanofamba netsoka, kuramba kutsvedza ndiko kwakanyanya kukosha. Zvidimbu zve silicon carbide micropowder zvinopararira zvakaenzana pamusoro pechifukidziro, zvichigadzira zvidiki, zvakaoma zvinowedzera kuomarara kwenzvimbo uye zvinowedzera coefficient yekukweshana.
Vashandi vakapfeka bhutsu dzekuchengetedza vanonzwa vakachengeteka pavanenge vachifamba nadzo; vanofamba netsoka kana kuchinaya kashoma kuti vatsvedze. Vimbiso yekuchengetedza iyi inokosha zvikuru.
Chechina, inoshanda zvakasiyana-siyana, ichidzivirira kupisa uye ngura.
Carbide yegirini yesilicon pachayo ine hunhu hwemakemikari hwakagadzikana, inodzivirira maasidhi, alkalis, oxidation, uye inobudirira munzvimbo dzinopisa zvakanyanya. Kuiisa mumachira kunopfuudza "hunhu" uhwu hwakanaka. Pamichina iri mumafekitori emakemikari kana mapaipi anopisa zvakanyanya, izvi zvinosimudzira kugara kwenguva refu kwemachira kusvika padanho idzva.
III. Kunyangwe chishandiso chakanaka chinoda hunyanzvi: Unyanzvi hwekushandisa
Ehe, chishandiso chakapinza chinoshanda zvakanaka chete kana mushandisi wacho achigona—haungangochishandisi usina ruzivo. Pane zvimwe zvinhu zvishoma zvirimo.
Kutanga, kusarudza saizi chaiyo yezvidimbu ibasa guru pacharo. Green silicon carbide powder inotangira pamazana kusvika kuzviuru zvema mesh. Kana ukashandisa giredhi rakakora zvakanyanya—ngatitii, 100 mesh kana kupfuura—pamusoro pechifukidziro chinonzwa chakaoma kana chikabatwa, zvichikanganisa runako. Kusiyana neizvi, kushandisa giredhi rakakora zvakanyanya—senge 3,000 kusvika 5,000 mesh—kunonyanya kuwedzera simba nekuoma asi kunoderedza kutsvedza. Saka, kusarudza kunofanira kuenderana nechinangwa chako chekupedzisira: paflooring, giredhi rakakora rinogona kukwana; kune matopcoats epamusoro-soro eindasitiri, giredhi rakakora rinogona kusarudzwa kuti riwedzere kukora pasina kukanganisa kuenzana.
Chechipiri, kudzora kwakanyatsojeka huwandu hwekuwedzera kwakakosha. Kuwedzera hakusi nyore. Zvidimbu izvi zvine simba guru, uye huwandu hwakawanda hunogona kukonzera kugadzikana. Kana chifukidziro chikagara kwenguva yakareba, chinoparadzana—mafuta akachena pamusoro, grit pasi—zvichisiya chisisina basa. Uyezve, kuwedzera zvakanyanya kunokanganisa zvakanyanya kuenzana kwechifukidziro uye kupenya, zvichikonzera mhedzisiro isina kunaka yeganda reorenji pamusoro pemvura yakapfapfaidzwa. Tinowanzowana chiyero chakanaka pakati pekushanda, kushanda, uye mutengo kuburikidza nekuyedza kakawanda.
Chekupedzisira, kupararira kwakakosha. Zvidimbu izvi zvidiki zvinoratidza simba rakasimba revan der Waals, zvichiita kuti zviungane. Kana zvisina kupararira zvakanaka, zvinoumba zvidimbu mukati mejira. Zvidimbu izvi hazvingobatsiri chete, asi zvinogadzirawo nzvimbo dzinokanganisa mashandiro ejira. Saka, mudziyo wekupararira wakakodzera unofanirwa kushandiswa pamwe chete nemichina yekupararira yakasimba kuti uve nechokwadi chekuti microparticle yega yega yakafukidzwa zvakakwana uye zvakaenzana neresin slurry. Ndipo chete panogona kuwanikwa kugona kwayo kwakazara.
