Kaolin wa ubweya: ubwino ndi ukulu

Vata Amakhala wa kaolin mullite CHIKWANGWANI ndi zimagawidwa monga zipangizo matenthedwe kutchinjiriza. Kumasiyana kugonjetsedwa ndi moto ndi amagwiritsidwanso ntchito kudzaza voids mu zomangamanga ndi mipata chisindikizo kagawo.

mafotokozedwe

Zofunika nthawi akuyendera mawonekedwe a masikono. Chifukwa amapangidwa m'kati kusungunuka oxides pakachitsulo ndipo zotayidwa pa kutentha mu ng'anjo wapadera. Kaolin wa ubweya kwa zaka zambiri mwakhama ntchito kutchinjiriza matenthedwe nyumba ndi outperforms zipangizo zina zambiri. Ngakhale zosiyanasiyana amakono a atumiki ndi katundu zofanana, izo kwayamba kutchuka kwambiri ndipo anapeza ntchito mu ntchito mafakitale. Iwo amachita monga matenthedwe kutchinjiriza zipangizo zipinda kuyaka, ndi kuzizira kutentha ndi turbines. Ambiri taonera mu makampani. Komanso kaolin wa ubweya ntchito kupanga slabs ndi zinthu zina kuumbidwa.

Mabukuwa ali mkulu mlingo phokoso ndi kutchinjiriza moto, kukana kuti mapindikidwe ndi kugwedera katundu. Komanso, thonje ali katundu zina khalidwe la zipangizo ambiri ndi cholinga ofanana. Njira chimateteza si bwanji ndi kutentha chilengedwe ndale kapena oxidizing, mlingo wa kukana akhoza ziwonjezeke ntchito okusayidi chromium. Ngakhale izi, chochitika chofunika ndi kukhala ndi kutentha zayamba yafupika m'mlengalenga kuchepetsa.

ubwino

Vata MKRR 130 abwino kwa chilengedwe cha ziyangoyango nanyema, kutchinjiriza akanema wa mauvuni ndi zomangamanga khoma. Imatha kulemera osachepera kuchepetsa kuchuluka kwa nthawi chofunika ndi khama wofunikila unsembe ndipo kumachepetsa mtengo kwa mafuta. Dziwani zinthu zina zabwino:

• ulusi bwinobwino kutsukidwa yodziwika ndi kukana mkulu devitrification;
• mlingo osachepera kutentha kudzikundikira;
• kukana kuti mantha matenthedwe;
• kuteteza makhalidwe choyambirira pa ntchito mobwerezabwereza;
• digiri yapamwamba ya kutchinjiriza cholamitsa;
• Si anakhudzidwa ndi mwamakani mankhwala zinthu, alkalis ndi zitsulo chimasungunula;
• inert mafuta zochokera mafuta mchere, ndi nthunzi ya madzi;
• makhalidwe magetsi kukhala zikutsatiridwa ngakhale pa kutentha.

Features

Kaolin wa ubweya zopangidwa aluminiyamu refractory, ozikidwa pa mchenga khwatsi. Mu wapadera miyala-m'ng'anjo isungunuke pa kutentha madigiri 1800. Mu zone limatsogolera azipereka maelekitirodi atatu, pamene pa malo a m'badwo wawo ndi awiri okha. njira ikuwomba ntchito kusungunuka zinthu, izo zinachokera pa mphamvu ya nthunzi wapadera malinga ndi mavuto za 0,7 MPa. Ejection nozzle amalola Ndime ya ndondomeko zonse ikuwomba. Monga binders atumikire madzi galasi, dongo kapena simenti.

Vata kaolin wa chogulitsidwa akhazikitsa mamita 10 m'litali, makulidwe ndipo m'lifupi masentimita 2 ndi masentimita 60, motero. Ndi kusintha, potero kupereka zoyenera snug chifukwa cha luso lililonse. Today, opanga akuyesa kusintha zinthu ndi Kuwonjezera zigawo zina, mwachitsanzo yttria. Izi bwino mtendere wa ulusi bwereza mwayi ntchito.

Zida kugonjetsedwa ndi moto

zipangizo Refractory anapangidwa kuchokera zapansi mchere ndi ndi kugonjetsedwa ndi kutentha, ndipo makhalidwe awo kukhala sichinasinthe. Iwo ili yofunika kwambiri mu kampani yopanga zitsulo kwa distillation, loopsali ndi zina njira, chilengedwe cha njira ya mkulu-kutentha (Motors, mathanki) ndi mbali kwa iwo. Pambuyo ntchito refractories wotumidwa kwa yobwezeretsanso.

Nthawi zambiri, mtundu wa mankhwala ali ndi amakona anayi mawonekedwe ndi otsika kulemera, kuwapanga abwino akalowa zosiyanasiyana. Panopa, pali kuchepetsa chosavuta kupanga refractories, monga kwambiri linaperekedwa kwa yopanga mortars wapadera ndi concretes, kugonjetsedwa ndi kutentha.

zipangizo Refractory: zotsimikizira njira

zipangizo Iwo ndi bokosi ceramic zopangidwa borides refractory, nitrides, oxides ndi kukhala mkulu mlingo wa mankhwala inertness ndi durability. Amagwiritsidwanso mpweya pawiri. Refractory kusunga katundu wawo atadziŵa kutentha pakati pa madigiri 1600 ndipo ntchito m'madera ambiri kumene kufunika kanthu zinthu anapatsidwa. Malinga ndi njira kupanga mankhwala anawagawa mitundu ingapo:

• otentha aakulu;
• aloyi, kukonzedwa kuchokera Sungunulani;
• pulasitiki kupanga;
• aloyi zochokera penoshlikera madzi;
• kudula kwa midadada kukonzedwa kapena miyala.
