Njerwa Yopanda Silika | Njerwa Yopanda Silika Yolimba ya SiO₂ Acid Yoteteza Ng'anjo Yotentha Kwambiri
Kukhala gawo lokwaniritsa maloto a antchito athu! Kumanga antchito osangalala, ogwirizana kwambiri komanso akatswiri ambiri! Kupeza phindu logwirizana kuchokera kwa ogula athu, ogulitsa, anthu onse komanso ife tokha.Njerwa Yopanda SilikaTsopano tili ndi gulu labwino kwambiri lopereka chithandizo cha akatswiri, yankho lofulumira, kutumiza zinthu pa nthawi yake, khalidwe labwino kwambiri komanso mtengo wabwino kwa makasitomala athu. Kukhutira ndi mbiri yabwino kwa kasitomala aliyense ndiye chinthu chofunika kwambiri kwa ife. Takhala tikuyembekezera mwachidwi kugwirizana ndi makasitomala padziko lonse lapansi. Tikukhulupirira kuti tingakukhutiritseni. Timalandiranso makasitomala mwachikondi kuti akacheze kampani yathu ndikugula zinthu zathu.
Njerwa zopingasa za silikandi zipangizo zapamwamba kwambiri zotetezera kutentha zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana otentha kwambiri.
1. Chidziwitso Choyambira
Zigawo Zazikulu:Ndi chinthu chopanda asidi chomwe chimakhala ndi silicon dioxide (SiO₂) ngati gawo lalikulu, nthawi zambiri chimakhala ndi zinthu zoposa 93%, ndipo njerwa za silika zapamwamba zimatha kufika pafupifupi 96%.
Kapangidwe ka Mankhwala Odziwika:Kupatula SiO₂, ilinso ndi Al₂O₃ yochepa (pafupifupi 0.8% - 1%), MgO (pafupifupi 0.001%), CaO (pafupifupi 0.002%), ndi Fe₂O₃ (pafupifupi 0.7% - 1.5%).
Katundu Wachilengedwe:Kukana kwa mphamvu nthawi zambiri kumakhala pakati pa 1770°C ndi 2000°C. Kukana kwa mphamvu pansi pa katundu wa 0.2MPa ndi 1630°C - 1680°C. Mphamvu yopopera yozizira ndi 30 - 35MPa, kuchuluka kwa mphamvu ndi 1.8g/cm³, ndipo porosity yooneka ndi 21% - 22%.
2. Njira Yopangira
Njira yopangira zinthu imaphatikizapo kusankha zinthu zopangira, kupanga mawonekedwe, kuyatsa moto, ndi kuziziritsa. Zinthu zopangira zazikulu ndi quartz, ndipo zomangira monga laimu ndi zomangira zachilengedwe zimawonjezedwa. Pambuyo popangidwa kukhala njerwa zopanda kanthu, zimayatsidwa kutentha kwakukulu kwa 1350°C - 1430°C. Njira yoyatsira moto imafuna kuwongolera kutentha koyenera, ndipo njira yoziziritsira iyeneranso kuchitika pang'onopang'ono kuti tipewe ming'alu yomwe imabwera chifukwa cha kusintha kwamphamvu kwa voliyumu.
Mawonekedwe:
1. Kukana kwambiri kukokoloka kwa asidi:Njerwa za silika zimalimbana kwambiri ndi zinthu zowononga monga asidi ndi chitsulo chosungunuka, zomwe zimapangitsa kuti zikhale ndi moyo wautali.
2. Kutentha kofewetsa katundu kwambiri:Kutentha kofewetsa katundu kwa njerwa za silika ndi kokwera kufika pa 1640-1670℃, ndipo voliyumu yake imakhala yokhazikika ikagwiritsidwa ntchito kwa nthawi yayitali kutentha kwambiri.
3. Kukhazikika kwa voliyumu yabwino:Pa kutentha kwakukulu kwa 1600℃, njerwa za silika zimatha kusunga kapangidwe kokhazikika komanso kukhala ndi liwiro lotsika la kukwera.
4. Kukhazikika kwa mankhwala:Njerwa za silika zimakhala ndi kukana bwino ma oxide monga Al2O3, FeO, Fe2O3, koma sizimakana bwino ndi alkaline slag (monga CaO, K2O, Na2O).

1. Njerwa za silika zimagwiritsidwa ntchito makamaka pa khoma logawa chipinda chopangira carbonization ndi chipinda choyaka cha uvuni wa coke, chipinda chokonzanso ndi chipinda cha sediment cha ng'anjo yotseguka ya chitsulo chopangira chitsulo, ng'anjo yotenthetsera yapakati, zinthu zotsutsana ndi ng'anjo yosungunula galasi ndi ng'anjo ya ceramic, ndi zina zonyamulira ng'anjo.
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.
