Dothi Losasinthika
Zambiri Zamalonda
Mtondo wopopera,wotchedwanso matope oyaka moto kapena zinthu zolumikizirana (ufa), zomwe zimagwiritsidwa ntchito ngati zinthu zomangira zomangira njerwa, malinga ndi zinthuzo zitha kugawidwa m'magulu awiri:dongo, aluminiyamu yambiri, silicon ndi magnesium refractory mortar, ndi zina zotero.
Imatchedwamatope wamba oletsa kukanaYopangidwa ndi ufa wa clinker wosasinthika ndi dongo la pulasitiki ngati chomangira ndi chopangira pulasitiki. Mphamvu yake pa kutentha kwa chipinda ndi yotsika, ndipo mapangidwe a ceramic bonding pa kutentha kwakukulu amakhala ndi mphamvu zambiri. Ndi hydraulicity, air hardening kapena thermo-hardening zipangizo monga chomangira, chotchedwamatope omangira mankhwala oletsa kukana, monga momwe zimakhalira pansi pa kupangika kwa kutentha kwa ceramic kumangirira musanapange mankhwala enaake ndi kuuma.
Makhalidwe a matope osasunthika:Kusungunuka bwino, kapangidwe kosavuta; mphamvu yolimba, kukana dzimbiri mwamphamvu; kukana kuzizira kwambiri, mpaka 1650℃±50℃; kukana bwino kulowetsedwa kwa slag; mphamvu yabwino yowononga kutentha.
Mtondo wopopera umagwiritsidwa ntchito makamaka mu uvuni wa coke, uvuni wagalasi, ng'anjo yophulika, chitofu chotentha, zitsulo, makampani opanga zinthu zomangamanga, makina, petrochemical, galasi, boiler, magetsi, chitsulo ndi chitsulo, simenti ndi uvuni wina wa mafakitale.

1. Dothi Losapanga Dongo Lokhala ndi Mpweya Wosapanga Dongo
Mapulogalamu Ofunika:Yoyenera kuyika njerwa zouma zopangidwa ndi dongo m'malo otentha ≤1350℃, monga magawo otentha a uvuni zamafakitale, ma flue, ma chimney, magawo otsika a ma hot blast stove regenerators, ndi ma boiler linings—zonsezi zili m'malo otentha pang'ono, kutentha kwapakati mpaka kotsika.
Mawonekedwe:Mtengo wotsika, wosavuta kugwira ntchito, wokana kutentha ndi kuzizira mwachangu; si woyenera malo osungunuka ndi matope osungunuka kwambiri/malo owononga kwambiri.
2. Mtondo wothira aluminiyamu wambiri
Ntchito zazikulu:NM-50/NM-60: Yoyenera njerwa zokhala ndi aluminiyamu yambiri (Al₂O₃ 55%~65%), zomwe zimagwiritsidwa ntchito mu gawo la kutentha kwapakati pa ma uvuni (1350~1500℃), monga ma uvuni a ceramic, ma uvuni otenthetsera zitsulo, ndi malo osinthira a simenti ozungulira; NM-70/NM-75: Yoyenera njerwa zokhala ndi aluminiyamu yambiri (Al₂O₃ ≥70%) kapena njerwa za corundum, zomwe zimagwiritsidwa ntchito mu gawo la kutentha kwambiri (1500~1700℃), monga ma linings a blast furnace, ma converter a steelmaking tapholes, ma regenerator a glass kiln, ndi ma linings a calcium carbide furnace.
Mawonekedwe:Kulimba kwambiri, kukana kwabwino kwa matope poyerekeza ndi matope opangidwa ndi dongo; kuchuluka kwa Al₂O₃ kukakhala kwakukulu, kukana kutentha kwambiri komanso kukana kukokoloka kwa nthaka kumakhala kolimba.
3. Silika Refractory Mota
Ntchito Zazikulu:Zimagwirizana ndi njerwa za silica, zomwe zimapangidwa makamaka kuti zikhale ndi asidi monga ma uvuni a coke, makoma a uvuni wagalasi/makoma a chifuwa, ndi ng'anjo zopangira zitsulo zokhala ndi asidi. Kutentha kwa nthawi yayitali: 1600~1700℃.
Mawonekedwe:Yolimba ku kukokoloka kwa asidi; imagwirizana bwino ndi njerwa za silika, koma imakana bwino alkali; yoletsedwa kugwiritsa ntchito mu uvuni za alkaline.
4. Massica / Magnesium-chrome Refractory Mortar
Ntchito Zazikulu: Massica:Zimagwirizana ndi njerwa za magnesia; zimagwiritsidwa ntchito m'malo okhala ndi matope amchere monga ma converter a alkaline steelmaking, makoma a ng'anjo yamagetsi, ndi ma ng'anjo zosungunulira zitsulo zopanda chitsulo.
Magnesium-chrome:Zimagwirizana ndi njerwa za magnesia-chrome; zimagwiritsidwa ntchito m'malo otentha kwambiri okhala ndi kukokoloka kwa alkaline monga malo oyaka moto a simenti, zotenthetsera zinyalala, ndi uvuni wosungunula zitsulo wopanda chitsulo.
Mawonekedwe:Kukana kwambiri kwa alkaline slag, koma kukana kofooka kutentha ndi kuzizira mwachangu; kutsatira malamulo a chilengedwe ndikofunikira pa magnesia-chrome refractory slurry (madera ena amaletsa kutulutsa kwa hexavalent chromium).
5. Silikoni carbide matope oletsa kuuma
Ntchito zazikulu:Yoyenera njerwa za silicon carbide/njerwa za silicon carbide zolumikizidwa ndi silicon nitride, zomwe zimagwiritsidwa ntchito mumlengalenga wotentha kwambiri, wosawonongeka, komanso wochepetsera kutentha monga malo opumira ng'anjo, zingwe zachitsulo, mapaipi okweza ng'anjo, ndi zipinda zina zoyatsira zinyalala.
Mawonekedwe:Mphamvu yoyendera kutentha kwambiri, kukana kuwonongeka kwambiri, kukana kusungunuka kwa okosijeni kutentha kwambiri, komanso nthawi yogwira ntchito bwino kuposa matope achikhalidwe a dongo/alumina.
6. Simenti yopanda simenti/simenti yolimba
Ntchito zazikulu:Yoyenera kupangira grouting/masonry a zinthu zophikidwa zopanda simenti/simenti kapena njerwa zooneka ngati refractory, zomwe zimagwiritsidwa ntchito popangira ma integral casting lining a ma uvuni akuluakulu a mafakitale komanso kupangira ma uvuni otenthedwa kwambiri (monga ma uvuni agalasi ndi ma uvuni amagetsi achitsulo), ndi kutentha kwa ntchito kwa 1400~1800℃.
Mawonekedwe:Madzi ochepa, kuchulukana kwambiri komanso mphamvu pambuyo poyatsa, palibe mavuto okulirapo omwe amayambitsidwa ndi madzi a simenti, komanso kukana kukokoloka kwa nthaka bwino.
Mbiri Yakampani
Shandong Robert New Material Co., Ltd.ili ku Zibo City, Shandong Province, China, komwe ndi malo opangira zinthu zopinga. Ndife kampani yamakono yomwe imagwirizanitsa kafukufuku ndi chitukuko, kupanga, kugulitsa, kapangidwe ndi zomangamanga za uvuni, ukadaulo, ndi kutumiza zinthu zopinga. Tili ndi zida zonse, ukadaulo wapamwamba, mphamvu yaukadaulo yamphamvu, khalidwe labwino kwambiri la malonda, komanso mbiri yabwino. Fakitale yathu imakwirira maekala opitilira 200 ndipo kutulutsa kwapachaka kwa zinthu zopinga ndi pafupifupi matani 30000 ndipo zinthu zopinga ndi matani 12000.
Zinthu zathu zazikulu zopangidwa ndi zinthu zotsutsa ndi izi:zipangizo zotsukira za alkaline; zipangizo zotsukira za silikoni ya aluminiyamu; zipangizo zosaoneka ngati zotsukira; zipangizo zotenthetsera kutentha; zipangizo zapadera zotsukira; zipangizo zogwirira ntchito zotsukira za makina opitira patsogolo.
Mafunso Ofunsidwa Kawirikawiri
Mukufuna thandizo? Onetsetsani kuti mwapita ku malo athu othandizira kuti mupeze mayankho a mafunso anu!
Ndife opanga enieni, fakitale yathu yakhala ikupanga zinthu zotsutsa kwa zaka zoposa 30. Tikulonjeza kupereka mtengo wabwino kwambiri, ntchito yabwino kwambiri yogulitsa zinthu zisanagulitsidwe komanso zitagulitsidwa.
Pa njira iliyonse yopangira, RBT ili ndi dongosolo lathunthu la QC la kapangidwe ka mankhwala ndi mawonekedwe ake. Ndipo tidzayesa katunduyo, ndipo satifiketi yaubwino idzatumizidwa ndi katunduyo. Ngati muli ndi zofunikira zapadera, tidzayesetsa momwe tingathere kuti zigwirizane nazo.
Kutengera kuchuluka kwa katundu, nthawi yathu yotumizira ndi yosiyana. Koma tikulonjeza kutumiza mwachangu momwe tingathere ndi mtundu wotsimikizika.
Inde, timapereka zitsanzo zaulere.
Inde, ndithudi, mwalandiridwa kupita ku kampani ya RBT ndi zinthu zathu.
Palibe malire, titha kupereka malingaliro abwino kwambiri komanso yankho malinga ndi momwe zinthu zilili.
Takhala tikupanga zinthu zopinga kwa zaka zoposa 30, tili ndi chithandizo champhamvu chaukadaulo komanso chidziwitso chambiri, titha kuthandiza makasitomala kupanga ma uvuni osiyanasiyana ndikupereka chithandizo chimodzi chokha.
