Njerwa ya Silika Mullite
Njerwa ya Silika mullitendi chinthu cholimba kwambiri. Zipangizo zazikulu zimaphatikizapo alumina bauxite clinker ndi silicon carbide, zomwe zimapangidwa kudzera mu njira monga kusakaniza, kupanga, kuumitsa ndi kuwombera kutentha kwambiri. Gawo lofunika kwambiri ndi kuwombera kutentha kwambiri, komwe kumapanga kapangidwe kabwino ka kristalo ka mullite mwa kuwongolera kutentha ndi mlengalenga moyenera. Ili ndi mphamvu yolimba kwambiri, kukana kuvala bwino komanso kukana kutentha kwambiri. Imatha kukhala yokhazikika m'malo otentha kwambiri ndipo siivuta kusweka kapena kuchotsa.
Njerwa za silika mullite andalusiteAmapangidwa makamaka ndi alumina bauxite yapadera yokhala ndi aluminiyamu wambiri, silicon carbide yayikulu-kristalo, andalusite, corundum yoyera yosakanikirana ndi zinthu zina zopangira. Amapangidwa powonjezera zomangira ndi zowonjezera zapamwamba, ndipo amapangidwa ndi kuumba kwamphamvu komanso kutentha kwambiri. Njira yopangirayi imatsimikizira kuchuluka kwapamwamba komanso mawonekedwe abwino kwambiri a njerwa zofiira za silicon-molybdenum.
Mbali:
Njerwa ya silika mullite:Kukana kutentha kwambiri; Kukana kutentha kwambiri; Kukana mankhwala bwino; Mphamvu yamakina kwambiri; Kukulitsa kutentha kochepa.
Njerwa za Silicon mullite andalusite:Mphamvu yayikulu komanso kukana kuvala; Kulimba bwino; Kuteteza kutentha bwino; Kuteteza kutentha kwambiri; Kuteteza kutentha kwambiri.

Njerwa za silika mullite andalusiteamagwiritsidwa ntchito kwambiri m'malo osinthira ndi m'malo ozizira a ma uvuni akuluakulu ndi apakatikati ozungulira simenti. Chifukwa cha kukana kwake moto komanso kukana kuwonongeka, njerwa zofiira za silicon-molybdenum zimatha kusintha moyo wa ntchito ndi magwiridwe antchito a zida.
Mu uvuni wozungulira wa simenti,njerwa za silika mulliteAmagwiritsidwa ntchito makamaka m'malo osinthira, m'malo otenthetsera, m'mapayipi opumira mpweya, m'matenthetsera oyambira asanu, ndi m'machubu otulutsira madzi a mu uvuni wa lime. Amalimbana ndi kukokoloka, kuphulika, komanso amakhala olimba mtima chifukwa cha kutentha.
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.
