Kodi Ufa Wotsitsimula Uyenera Kukhala Ndi Zinthu Zotani?

Kuphatikiza pakukwaniritsa zofunikira zogwirira ntchito zokutira, themafuta opopera ufaiyeneranso kukwaniritsa zofunikira za kupopera mbewu mankhwalawa: imatha kunyamulidwa mumoto wamoto wa jet mofanana, bwino komanso mokhazikika kuti iwonetsetse kuti ikhale yokhazikika komanso yofanana ndi yopopera mankhwala.Choncho, makhalidwe ofunika a ufa monga mawonekedwe, tinthu kukula ndi tinthu kukula kugawa, kachulukidwe chochuluka, fluidity ndi pamwamba khalidwe, ndi zofunika zigawo zikuluzikulu za ntchito ya matenthedwe kutsitsi ufa.

(1) Morphology ya particles ufa

Ambiri mwa matenthedwe kupopera mbewu mankhwalawa aloyi ufa zipangizo zakonzedwa ndi njira atomization, ndi ufa tinthu morphology makamaka amatanthauza mawonekedwe a geometric ndi pamwamba makhalidwe a particles ufa.Geometry ikhoza kuyesedwa poyesa chiŵerengero cha axis yaifupi kumtunda wautali (mtengo wamtengo wapatali) wa elliptical spherical particles.Kukwera kwa digiri ya spheroidization, kumapangitsa kuti ufa wokhazikika ukhale wabwino.Popeza mlingo wa ufa spheroidization si zogwirizana ndi atomization ufa mphero njira ndi atomization mphero magawo magawo, komanso mankhwala zikuchokera ufa palokha.Choncho, digiri ya spheroidization ya mitundu yosiyanasiyana ya ufa ndi yosiyana, koma ziyenera kuwonetseredwa kuti kupopera mbewu mankhwalawa kungakhale kosalala komanso ngakhale kudyetsa ufa.

Nthawi zina pamakhala mabowo amitundu yosiyanasiyana mkati mwa tinthu tating'onoting'ono ta zitsulo tating'ono tomwe timakonzedwa ndi atomization, zina zomwe zimadutsa pamwamba, ndipo zina zimatsekedwa mkati mwa particles.Ngati kupopera mbewu mankhwalawa sikuli koyenera, kudzakhudza mwachindunji ubwino wa zokutira.Kuti muwone mabowo oterowo, makina owonera a metallographic nthawi zambiri amagwiritsidwa ntchito.Mawonekedwe a pamwamba amatanthauza mtundu wa pamwamba, kusalala, ndi zina.

(2) Chigawo cha ufa

Kusankhidwa kwa tinthu ting'onoting'ono ndi kukula kwake kumatsimikiziridwa ndi kupopera mbewu mankhwalawa njira ndi kupopera mbewu mankhwalawa ndondomeko yeniyeni.Ngakhale ufa tinthu kukula osiyanasiyana ndi yemweyo, chiwerengero cha tinthu kukula kalasi zikuchokera si chimodzimodzi.Mwachitsanzo: ngakhale tinthu kukula tinthu mu osiyanasiyana 125μm ~ 50μm (-120mesh ~ + 320mesh), chiwerengero cha ufa atatu osiyana tinthu kukula sukulu 100μm ~ 125μm, 80μm ~ 100μm, 50μm ~ 80μm si yemweyo. .The ufa tinthu kukula osiyanasiyana ndi tinthu kukula kalasi zikuchokera zimakhudza mwachindunji ❖ kuyanika khalidwe, ufa chochuluka osalimba ndi fluidity.

(3) Kuchulukana Kwambiri kwa Ufa

Kachulukidwe kaufa kachulukidwe ka ufa kumatanthauza kuchuluka kwa ufa pa unit imodzi pamene wapakidwa momasuka.Popeza kachulukidwe kachulukidwe ka ufa umagwirizana ndi digiri ya spheroidization ya ufa, kukula ndi kuchuluka kwa mabowo mkati mwa tinthu tating'onoting'ono, komanso mawonekedwe a tinthu tating'onoting'ono, zimakhudzanso mtundu wa zokutira zopopera.

(4) Kuchuluka kwa ufa

The fluidity of powder ndi nthawi yofunikira kuti ufa wodziwika bwino uziyenda momasuka kudzera muzitsulo zokhazikika zokhala ndi pobowo.Nthawi zambiri imadziwika ndi nthawi (s) yofunikira kuti 50g ufa udutse mumsewu wokhazikika wokhala ndi mainchesi a 2.5mm.Zimakhudza kwambiri kupopera mbewu mankhwalawa komanso kupopera mbewu mankhwalawa moyenera.
