Njerwa Zosapanga Dongo
Njerwa za dongo loyaka motoNdi zinthu zofewa zopangidwa ndi silico-aluminiyamu zokhala ndi Al₂O₃ ya 35%–45%. Zimapangidwa makamaka kuchokera ku kaolin, zimapangidwa kukhala mawonekedwe, zouma, kenako zimawotchedwa pa kutentha kwakukulu kwa 1300–1400℃. Panthawi yowotcha, makhiristo a mullite amapangidwa. Ndi kufewa kwa 1690–1730℃, njerwa zadothi loyaka moto zimagawidwa ngati zinthu zofewa zofewa zofewa zofewa.
Kugawa
Njerwa za dothi loyaka moto zitha kugawidwa m'magulu anayi: wamba, wokhuthala, wotsika, komanso wosagwirizana ndi kutentha, zomwe zimakhala ndi mitundu yosiyanasiyana yokhala ndi Al₂O₃ kuyambira 25% mpaka 45%. Malinga ndi momwe zimagwiritsidwira ntchito, zimagawidwa m'magulu atatu: omwe ndi a ng'anjo zoyaka moto, ma stovu otentha, ndi ma ng'anjo agalasi.
Makhalidwe Ofunika:
Njerwa za dongo zoyaka moto zimalimbana bwino ndi dzimbiri la asidi komanso dzimbiri la mpweya wa asidi, koma zimakhala ndi kukana kochepa kwa zinthu za alkaline. Zimakhala ndi kukana kwabwino kwa kutentha: kutentha kwa 0–1000℃, kuchuluka kwawo kumawonjezeka mofanana ndi kutentha komwe kumawonjezeka, ndi kuchuluka kwa kukula kwa 0.6%–0.7%, komwe kuli pafupifupi theka la njerwa za silika. Komabe, kukana kwawo pansi pa katundu kumakhala kotsika kuposa 200℃ kuposa kwa njerwa za silika, ndipo kuchepa kwa voliyumu kumachitika kutentha kukapitirira 1200℃.

Makampani Ogulitsa Zitsulo
Mu makampani opanga zitsulo, njerwa zothira dongo zimagwiritsidwa ntchito makamaka mu zipangizo monga ng'anjo zophulitsa moto, ng'anjo zophulitsa moto ndi ma uvuni agalasi. Njerwa zothira dongo zothira dongo zophira moto zimatha kupirira kutentha kwambiri komanso mlengalenga wowononga kuti ziteteze kapangidwe ka ng'anjo; njerwa zothira dongo zothira dongo zophira moto zimagwiritsidwa ntchito popangira ng'anjo zophulitsa moto kuti zitsimikizire kuti zikugwira ntchito bwino; njerwa zazikulu zothira dongo zophira moto zophira magalasi zimagwiritsidwa ntchito mu ng'anjo zosungunula magalasi kuti zitsimikizire kukhazikika komanso kukana moto pa kutentha kwambiri.
Makampani Amankhwala
Mu makampani opanga mankhwala, njerwa zouma zimagwiritsidwa ntchito ngati zotetezera kutentha pa zipangizo monga ma reactor, ma flickering furnaces ndi ma synthesis furnaces. Zipangizozi zimagwira ntchito pansi pakutentha kwambiri ndi mlengalenga wowononga, ndi njerwa zouma zitha kuchepetsa kutaya kutentha ndikuwonjezera kugwiritsa ntchito mphamvu moyenera.
Makampani a Ceramic
Mu makampani opanga zinthu zadothi, njerwa zouma zimagwiritsidwa ntchito popangira makoma ndi madenga a zinthu zotetezera kutentha.ma uvuni ophikira ndi ceramic kuti asunge kutentha kwambiri mu uvuni ndikulimbikitsa kuwotcha zinthu za ceramic. Dongo lolimba ndi dongo lolimba pang'ono zimagwiritsidwa ntchito ngati zopangira popanga ma ceramic omwe amagwiritsidwa ntchito tsiku ndi tsiku, ma ceramic omanga ndi mafakitale.zoumbaumba.
Makampani Omanga Nyumba
Makampani Mu makampani opanga zinthu zomangira, njerwa zouma zimagwiritsidwa ntchito popanga ma uvuni a simenti ndi ma uvuni osungunula magalasi.
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.
