Kafukufuku Wokhudza Mphamvu ya Brown Fused Alumina Micropowder pa Kuuma kwa Zinthu
Mu ntchito yathu, makamaka pokonza pamwamba kapena kukonza zinthu, timakumana ndi chizindikiro cha "kukhwima" pafupifupi tsiku lililonse. Zili ngati "chala" cha chinthu, chomwe chimatsimikizira mwachindunji ngati chophimba chotsatira chingamamatire, momwe ziwalozo zilili zolimba, komanso momwe chimatsekereza. Lero, tisalankhule za malingaliro apamwamba amenewo, koma tikhale pansi ndikucheza ngati anzathu anzathu akale odziwika bwino - ufa wa alumina wofiirira - ndi momwe "umathandizira" kukhwima pamwamba pa zinthu.
I. Choyamba, tiyeni timvetse: Kodi ufa wa alumina wosakaniza ndi bulauni ndi chiyani kwenikweni?
Alumina wofiirira wosakanikiranaMwachidule, ndi zomwe "timayenga" pogwiritsa ntchito zipangizo monga alumina ndi coke mu uvuni wamagetsi. Chifukwa chakuti uli ndi titaniyamu ndi iron oxides, uli ndi mtundu wa bulauni, ndichifukwa chake umatchedwa. Uli ndi kuuma kwakukulu, kulimba bwino, ndipo ndi wotsika mtengo, zomwe zimapangitsa kuti ukhale "wofunika kwambiri" pakupukuta mchenga ndi kupukusa.
Ndipo mawu oti “ufa waung'ono” ndi ofunikira kwambiri. Amatanthauza ufa wosalala kwambiri womwe umapezeka pophwanya ndi kutsekereza alumina wofiirira wosakanikirana kudzera mu njira yapadera, wokhala ndi tinthu tating'onoting'ono tomwe nthawi zambiri timakhala pakati pa ma meshes mazana angapo mpaka zikwi zingapo. Musanyoze ufa uwu; sulinso “mpeni wodula nkhuni,” koma “mpeni wosema” wolondola. Kutuluka kwake kwalola alumina wofiirira wosakanikirana kusintha kuchoka pa ntchito zolemetsa monga kuchotsa sikelo yokhuthala ya oxide kuchokera ku zinthu zotayidwa kupita ku malo opangira zinthu molondola, komwe kumafunika mtundu wapamwamba kwambiri wa pamwamba.
II. Kodi "Imajambula" Bwanji Pamwamba? - Dziko Lodabwitsa la Microscopic
Anthu ambiri amaganiza kuti kuphulika kwa mchenga ndi kungogunda pamwamba ndi mchenga, ndipo ukagunda molimbika, kumakhala kovuta kwambiri. Zimenezo ndi zoona, koma kwa ife amene timaphunzira za ufa waung'ono, theka lina ndiye maziko ake. Mphamvu ya ufa wa alumina wofiirira wosakanikirana pa kuuma kwa pamwamba ndi njira yovuta, yomwe ndimafotokoza m'magawo atatu akuluakulu:
Zotsatira za "Kuboola" (Kudula Kwakukulu): Iyi ndi njira yodziwikiratu kwambiri. Tinthu tating'onoting'ono touluka mwachangu, monga nyundo ndi ma tchizo osawerengeka, timakhudza pamwamba pa chinthucho. Tinthu tolimba "tidzaluma" mwachindunji pa chinthucho, ndikupanga mabowo ang'onoang'ono. Gawo ili ndilo limayambitsa kukhwima kwa pamwamba mofulumira. Tangoganizirani malo osalala akuchotsedwa ndi mabowo ang'onoang'ono osawerengeka; kusiyana pakati pa nsonga ndi zigwa kumawonjezeka kwambiri, mwachibadwa kumakweza kuchuluka kwa kukhwima (monga, Ra, Rz).
"Kulima" (kusintha kwa pulasitiki): Izi n'zosangalatsa. Tinthu timeneti tikamapanda kukhudza pamwamba molunjika, koma m'malo mwake "timakanda" mopingasa, sitingadule mwachindunji zinthuzo. M'malo mwake, monga kulima, "timakankhira" zinthuzo m'mbali, ndikupanga "mzere wokwezeka." Njirayi siichotsa zinthuzo mwachindunji, koma kudzera mu kusintha kwa pulasitiki, imasintha mawonekedwe a pamwamba, ndikuwonjezera kusiyana pakati pa nsonga ndi zigwa.
Zotsatira za "Kukakamira" ndi "kutopa": Pansi pa kugwedezeka kosalekeza kwa tinthu tating'onoting'ono, pamwamba pa chinthucho pamakhala njira "yokonzanso" kudzera mu kugwedezeka mobwerezabwereza. Kugwedezeka koyambirira kumatha kumasula pamwamba, koma kugwedezeka kosalekeza kwenikweni "kumalimbitsa" pamwamba, ndikupanga gawo lolimba komanso lolimba. Nthawi yomweyo, kugwedezeka mobwerezabwereza kumabweretsa kutopa pa kapangidwe ka pamwamba pa chinthucho, zomwe zimapangitsa kuti tinthu totsatira tichotsedwe mosavuta.
Monga mukuonera, ngakhale njira yosavuta yophulitsira mchenga imakhala ndi zotsatira zitatu nthawi imodzi komanso zogwirizana wina ndi mnzake m'dziko la microscopic: "kukumba," "kulima," ndi "kuponda."
III. Zinthu Zitatu Zofunika Kwambiri Zomwe Zimakhudza Zotsatira: Kukula kwa Tinthu, Kupanikizika, ndi Ngodya
Tsopano popeza tamvetsa mfundoyi, kodi "tingalamulire" bwanjiufa wa alumina wofiirira wosakanikiranaKodi mukufuna kukwaniritsa kuuma kwa pamwamba komwe mukufuna pakugwira ntchito kwenikweni? Zimadalira makamaka zinthu zitatu izi:
Choyamba: Kukula kwa Tinthu (Kodi ufawo uyenera kukhala wolimba bwanji?)
Iyi ndiye mfundo yofunika kwambiri. Mwachidule, pansi pa mikhalidwe yomweyi, tinthu tating'onoting'ono tikakhala tolimba, tinthu tating'onoting'ono timakhala tolimba kwambiri. Kugwiritsa ntchito ufa wa ma mesh 80 kumapanga malo ouma kwambiri pakangopita nthawi yochepa; koma ngati mugwiritsa ntchito W40 kapena ufa wosalala kwambiri, malo otsatirawa adzakhala osalala kwambiri komanso okhala ndi mawonekedwe abwino. Izi zikufanana ndi kupukuta matabwa ndi sandpaper yolimba poyerekeza ndi sandpaper yosalala—zotsatira zake zimakhala zosiyana kwambiri. Chifukwa chake, kuti mupeze malo ouma pang'ono, kusankha ufa wosalala ndiye gawo loyamba.
Chinthu chachiwiri chofunikira: Kupanikizika kwa kupopera (Mphamvu yochuluka bwanji?)
Kupanikizika ndi mphamvu yomwe imaperekedwa ku tinthu tating'onoting'ono. Kupanikizika kwakukulu, tinthu tating'onoting'ono timauluka mofulumira, mphamvu ya kinetic imakhala nayo, ndipo mphamvu ya "kukumba" ndi "kulima" imakhala yolimba kwambiri, zomwe zimapangitsa kuti zikhale zovuta kwambiri. Komabe, pali vuto: kupanikizika kwakukulu sikukhala bwino nthawi zonse. Kupanikizika kwambiri kungayambitse kudula kwambiri, ngakhale kuwononga kulondola kwa gawo la ntchito, kapena kuswa zipangizo zosweka. Zomwe takumana nazo n'zakuti, pamene tikukwaniritsa zofunikira zoyeretsa ndi zokhwima, ndi bwino kugwiritsa ntchito kupsinjika kochepa kwambiri—"gwiritsani ntchito chitsulo chabwino kwambiri pamene chili chofunika."
Chinthu chachitatu chofunikira: Ngodya yopopera (Kuchokera mbali iti?)
Anthu ambiri amanyalanyaza izi. Kafukufuku akusonyeza kuti pamene ngodya yopopera ili pakati pa 70° ndi 90° (pafupifupi yopingasa), kuwonjezeka kwa kukhwima ndikofunikira kwambiri chifukwa zotsatira za "kukumba" zimakhala zazikulu. Pamene ngodyayo imakhala yocheperako (monga 30°-45°), zotsatira za "kulima" zimakhala zoonekera kwambiri, zomwe zimapangitsa kuti mawonekedwe a kukhwima akhale osiyana. Ngati tikufuna kuyeretsa pamwamba koma sitikufuna kuti pakhale kukhwima kwambiri, nthawi zina timagwiritsa ntchito ngodya yocheperako kuti tipeze mgwirizano pakati pa kuyeretsa ndi kukhwima.
IV. "Zinsinsi" ndi Malingaliro Okhudza Kugwiritsa Ntchito Mwachizolowezi
Chiphunzitso chokha sichikwanira; pali “zinsinsi” zambiri zomwe zimapezeka mu ntchito yeniyeni.
Mwachitsanzo, "kutentha" kwa chinthucho (makhalidwe enieni a chinthucho) ndikofunikira kwambiri. Kugwiritsa ntchito magawo omwewo popanga chitsulo cholimba kwambiri poyerekeza ndi aluminiyamu yofewa kumabweretsa zotsatira zosiyana kwambiri. Zipangizo zofewa zimakhala zosavuta kusintha pulasitiki, zimapangitsa "mipata" yakuya komanso yayikulu ndipo zimatsekeka mosavuta; zipangizo zolimba zimatha kusweka mosavuta, ndikupanga mabowo ambiri.
Chitsanzo china ndi "nthawi ya moyo" wa ufa wa micro-powder.Ufa wa alumina wofiirira wosakanikiranaidzawonongeka ndi kusweka pakapita nthawi. Ufa watsopano umakhala ndi kukula kofanana kwa tinthu tating'onoting'ono, m'mbali zakuthwa, komanso mphamvu yodula yamphamvu, zomwe zimapangitsa kuti ukhale wolimba komanso wofanana. Komabe, ufa wogwiritsidwa ntchito, wokhala ndi m'mbali zozungulira komanso tinthu tating'onoting'ono, umakhala "wakale komanso wosweka," wokhala ndi mphamvu yocheperako yodula, zomwe zingapangitse kuti ukhale wolimba komanso wofanana, woyenera kumalizidwa bwino "satin" pamwamba. Zonse zimadalira zomwe mukufuna pa ndondomeko yanu.
Chifukwa chake, kuphunzira zotsatira zaufa wofiirira wosakanikirana wa alumina microKukhwima pamwamba si nkhani yongoyang'ana zinthuzo ndikugwira ntchito moyenera. Ndi luso lowongolera molondola dziko la microscopic. Tiyenera kukhala ngati dokotala wachikhalidwe waku China wodziwa bwino ntchito yake, wodziwa bwino ntchito zake ndi njira zake monga "tinthu tating'onoting'ono, kuthamanga, ndi ngodya," kenako n'kuziphatikiza ndi "kapangidwe" ka zinthu zogwirira ntchito, kuti tipeze "mankhwala" ogwira ntchito bwino kwambiri ndikukwaniritsa kukhwima kwabwino kwambiri pamwamba.
