Refractories Pakuti Glass Ng'anjo

Zida zazikulu zotenthetsera zopangira magalasi, monga kachulukidwe kakachulukidwe, ma groove angapo, njira yodyetsera ndi kachulukidwe kakang'ono ka magalasi, amapangidwa makamaka ndi zinthu zotsutsana.tntchito yabwino komanso moyo wautumiki wa zida ndi mtundu wagalasi zimadalira kwambiri mtundu ndi mtundu wa zida zomwe zimagwiritsidwa ntchito.tKupita patsogolo kwa ukadaulo wopanga kumadalira kuwongolera kwaukadaulo waukadaulo wopangira zinthu komanso khalidwe labwino kwambiri. Choncho, m'pofunika kusankha mwanzeru ndi kupangait ndikofunikira kwambiri kugwiritsa ntchito ma refractories popanga komanso kugwiritsa ntchito tsiku ndi tsiku zida zotenthetsera magalasitiye chachiwiri ndi mikhalidwe utumiki ndi dzimbiri limagwirira mbali zosiyanasiyana za zipangizo matenthedwefZida zoyaka moto zimatanthawuza zinthu zopanda zitsulo kapena zinthu zomwe sizingagwirizane ndi moto zosachepera 1500 ℃ (1580 ℃ ku China ndi komwe kale kunali Soviet Union)it itha kukhala zopangira zachilengedwe, zimathanso kukhala zopangidwa ndi anthu ndi zida, zokanira kuwonjezera pamlingo wina wa kukana moto, komanso zimafunika kukhala ndi kuthekera

Main luso ntchito dongosolo:

① Kuti akwaniritse zofunikira pakugwira ntchito kwa kutentha kwakukulu, sikuyenera kufewetsa ndikusungunuka kutentha kwakukulu;

② Imatha kunyamula katundu wa ng'anjo ndi kupsinjika pakugwira ntchito, ndikukhala ndi zovuta zina pa kutentha kwakukulu.;

Palibe kutayika kwa mphamvu zamapangidwe, mapindikidwe ndi kulephera;

③ Kukhazikika kwa kutentha kwakukulu sikungapangitse mthunzi wochuluka kapena kuchepa, zomanga za ng'anjo yamoto kapena kutsanulira thupi sizingachepe chifukwa cha kuchuluka kwa voliyumu.eming'alu kapena ming'alu yomwe ilipo;

④ Kukana kwa kutentha kwa kutentha sikumatuluka pansi pa kutentha kwina ndi kugwedezeka kwa kutentha;

⑤ Anti invasion performance imatha kupirira nthawi yayitali ya gasi, yamadzimadzi komanso yolimba yowononga popanda kukokoloka mwachangu, ndipo imatha kupirira dzimbiri.okuchepetsa xidation pa kutentha kwakukuluitimatha kupirira kutentha kwambiri komanso kuthamanga kwambiri kwamoto ndi utsi, kukokoloka kwazitsulo zamadzimadzi ndi slag, komanso kutsika kwamphamvu.iPact akupera zitsulo ndi zipangizo zina;

② Kuwunika kwa kutentha kwa kukana kwamafuta ndi katundu wotsalira kumatanthawuza kugwa ndi kuyesa kutsika kwa thupi la njerwa chifukwa cha kusintha kwa kutentha. Kapangidwe.

Kugwa kumatanthawuza kuti kusungunuka kwa ma refractories kumalowera mu njerwa motsatira pores ndi ming'alu yake, ndikulumikizana nayo kuti ipange mawonekedwe omwewo ngati apachiyambi..

Pamene kutentha kumasintha kwambiri, wosanjikiza wa metamorphic wokhala ndi njerwa zosiyanasiyana ndi katundu adzasweka ndi kugwa.

Makampani opanga magalasi ndi apadera chifukwa gawo lophwanyika la galasi wandiweyani sulfure lidzakhalabe mu galasi lamadzimadzi ngati lingathe kusungunuka..

Mu galasi, kapangidwe ka galasi kumangokhudzidwa pang'ono, zomwe sizivulaza galasi limodzi, koma osati galasi lapadera..

Xu: ngati sichingasungunuke kwathunthu, zolakwika zingapo zamagalasi monga miyala, tinthu tating'onoting'ono ndi thovu zidzapangidwa, zomwe zimabweretsa zinyalala. Mbali inayo.

Pakalipano, moyo wautumiki wa galasi loyandama la China lafika zaka 50.

Zoposa zaka 8, komabe pali kusiyana kwakukulu poyerekeza ndi mayiko omwe ali ndi makampani opanga magalasi otukuka. Choncho, khalidwe la refractory ndiye chinsinsi cha khalidwe la galasi.

Zinthu zazikulu za chitukuko cha mafakitale

Makhalidwe a refractories a galasi ng'anjo

Refractories ndi gulu la ma multiphase ndi ma multicomponent complex system, omwe amapangidwa ndi mitundu yosiyanasiyana yamitundu yosiyanasiyana yamankhwala ndi mchere wokhala ndi mawonekedwe osiyanasiyana.

Plasitidi. The katundu refractories zimagwirizana kwambiri ndi mankhwala zikuchokera, gawo zikuchokera, bonding morphology ndi kugawa, komanso makhalidwe a gawo lililonse.

mankhwala opangidwa

The mankhwala zikuchokera refractories ndi chimodzi mwa zinthu zofunika kudziwa katundu wa refractories.The mankhwala zikuchokera refractories akhoza kugawidwa m'magawo awiri molingana ndi zikuchokera ndi ntchito: chigawo chachikulu chimene chimawerengera kuchuluka kwa mtheradi ndipo amasewera motsimikiza. gawo pakuchita kwake, ndipo kachigawo kakang'ono kamene kamawerengera pang'ono amatchedwa gawo lachiwiri. Chigawo chachiwiri chimaphatikizapo chigawo chodetsedwa chomwe chimatsagana ndi zopangira ndi zowonjezera zomwe zawonjezeredwa kuti zikwaniritse cholinga china.

(1) Chigawo chachikulu cha chigawo chachikulu ndikupangidwa kwa matrix a nthawi yamoto mu zokanira, zomwe nthawi zambiri zimakhala mtundu umodzi kapena zingapo za ma oxides osungunuka kwambiri kapena ma non oxide omwe amapangidwa ndi mchere wambiri. Kuchita kwake ndi kuchuluka kwake kumatsimikizira mwachindunji zida zamoto wanthawi. Zida zoyaka moto zimatha kugawidwa kukhala asidi, zamchere komanso zopanda ndale molingana ndi mankhwala awo.

(2) Chigawo chonyansa chimatanthawuza zinthu zokanira zomwe zimabweretsedwa kapena kusakanizidwa popanga chifukwa chogwiritsa ntchito zinthu zachilengedwe zopangira mchere.

Nthawi zambiri, Ko, Nao, FeO ndi FeO ndi zida zozimitsa nthawi

Zoyipa zowononga zomwe zili m'thupi. Kuphatikiza apo, acid oxide (ro2) ndi acid oxide mu zinthu zoyambira za pyrotechnic (RO ndiye chigawo chachikulu) amawonjezekanso.

Ma oxides omwe ali muzinthu za pyrotechnic amawonedwa ngati zinthu zovulaza, zomwe zimakhala ndi mphamvu yosungunuka pa kutentha kwakukulu. Zotsatira zake sizodziwikiratu

Kutentha kokha kwa eutectic madzi gawo kumachepa ndipo kuchuluka kwa madzi kumawonjezeka, ndipo ndi kuwonjezeka kwa kutentha, kuchuluka kwa madzi kumachepa.

Kuthamanga kowonjezereka kumafulumizitsa, zomwe zimakhudza kwambiri kutentha kwa zinthu zotsutsana. Choncho, m'pofunika kulamulira zonyansa zikuchokera motsika momwe n'kotheka

Mwachitsanzo, chigawo chachikulu cha njerwa ya silika ndi SiO, ndipo zigawo zovulaza zikuphatikizapo Ao, ku ndi alkali metal oxides. American Standard

Ndikofunikira kuti zonse zomwe zili zonyansa muzophwanya ma silicon breaker ndi zosakwana 0.5%, ndipo zomwe zili mu Ao mu British standard silicon breaker ndi 0.3%

Pali mitundu iwiri ya kusinthasintha kwa zonyansa zomwe zili ndi a1o zosakwana 0.6%

(1)Chifukwa cha zochita mankhwala, otsika kusungunuka madzi gawo aumbike;(2)The madzi gawo anapanga yemweyo kutentha si kwenikweni otsika kusungunukalarge kuchuluka.

(3) Kuti apititse patsogolo magwiridwe antchito akuthupi, magwiridwe antchito komanso magwiridwe antchito a refractory, kuwonjezera pakupanga mankhwala pakupanga kapena kugwiritsa ntchito refractory..

Zowonjezera zochepa zomwe zingathe kuwonjezeredwa kuti ziwongolere ntchito za mankhwala zimatchedwa zowonjezera. Mlingo wa zowonjezera umasiyana ndi katundu ndi ntchito zawo, ndipo nthawi zambiri zimakhala zotsika.

Ndi zikwi khumi mpaka khumi peresenti yazinthu zonse za pyrotechnic. Zowonjezera zitha kugawidwa m'magulu otsatirawa malinga ndi zolinga ndi ntchito zawo:

(1）Nthawi moto zinthu akaphatikiza kumanga ntchito kalasi: binder, wotchedwanso cementing wothandizira kapena woyimirira;(2）sinthani makonzedwe ndi kuuma kwa kalasi: kuphatikiza wothandizira, polar wothandizira ndi zina zotero;(3）kusintha rheological katundu: kuphatikizapo madzi reducer, plasticizer, gelling wothandizira ndi degumming wothandizira, etc;(4）Sinthani gulu lamkati Kalasi ya kamangidwe: kuphatikiza thovu, defoamer, shrinkable agent, kutupa, etc.;(5）kupititsa patsogolo kalasi yolimba: kuphatikiza choletsa, chosungira, anti-edema agent, etc. Cryoprotectants, etc; Kupititsa patsogolo ntchito, kuphatikizapo sintering aid, mineralizer, fast drying agent, stabilizer, etc. Hydration resistance; Antioxidant, anti kuchepetsa wothandizira, etc..

Pali mitundu yambiri ya zowonjezera, zomwe ndizinthu zazikulu zofufuzira mumakampani azinthu zozimitsa moto

Zochepa: 2. Ikhoza kusintha mwachiwonekere ntchito zina kapena makhalidwe a zinthu zotsutsana; 3. Zilibe mphamvu yaikulu pazinthu zazikulu za mankhwala, monga kupanga njerwa za silika.

Kuwonjezera mkaka wa laimu ndi chitsulo ndi mineralizer kuti apange mapangidwe a quartz; Cao yowonjezeredwa ku mankhwalawa ndi stabilizer kuti mankhwalawa akhale okhazikika.

Zotsatira zikusonyeza kuti kiyubiki ZrO 2 anapanga pa kutentha ndi khola pa kutentha otsika: MgO ndi zina zina mu chiyero mkulu Al 2O zoumba ndi sintering zothandizira.high kachulukidwe sinter angapezeke pa kutentha otsika.
