Chifukwa cha kuwonjezeka kwa kufunika kwa mpweya wabwino wa m'nyumba komanso mpweya wabwino wosagwiritsa ntchito mphamvu zambiri,zosinthira kutentha kwa ceramic za uchi- chinthu chachikhalidwe cha mafakitale chomwe chimatentha kwambiri - chikulowa mu makina a mpweya wabwino. Kapangidwe kake kapadera kokhala ndi mabowo, magwiridwe antchito okhazikika, komanso kugwiritsidwanso ntchito bwino kumathetsa mavuto akuluakulu a makina achikhalidwe, monga ndalama zambiri zosinthira zosefera komanso nthawi yochepa yogwirira ntchito, zomwe zimapangitsa kuti mpweya wamkati ukhale wothandiza komanso wotsika mtengo.
Chosinthira kutentha cha ceramic cha uchi ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri m'mafakitale, ndipo chimagwira ntchito yofunika kwambiri mu dongosolo la mpweya wabwino. Kapangidwe kapadera ka thupi losungira kutentha la ceramic la uchi kumapatsa ubwino waukulu pakulola mpweya kulowa bwino komanso kugwiritsa ntchito bwino kusinthana kutentha. Pansipa, tikambirana mwatsatanetsatane momwe matupi osungira kutentha a ceramic a uchi amathandizira pakugwira ntchito kwa machitidwe a mpweya wabwino.
1. Makhalidwe a kapangidwe kake ndi kufalikira kwa mpweya
Kapangidwe ka chosungira kutentha cha ceramic cha uchi cha uchi chimapangidwa ndi ma pores ambiri okonzedwa bwino okhala ndi ma hexagonal kapena sikweya, omwe amapereka njira yofanana ndi msewu waukulu wa mamolekyu a gasi. Kapangidwe kameneka kamalola mamolekyu a gasi kulowa m'ma pores popanda zopinga zilizonse, ndikuyamba 'ulendo wothamanga kwambiri'. Mosiyana ndi zipangizo zina zokhala ndi ma microstructure ovuta komanso ovuta, ma pores a zosungira kutentha za ceramic za uchi ndi olunjika komanso opitilira, amachepetsa kwambiri kugundana ndi zopinga za mamolekyu a gasi panthawi yoyenda kwawo.
2. Kusinthana kwa kutentha mu dongosolo la mpweya wabwino
Mu dongosolo la mpweya wabwino, malo osungiramo kutentha kwa ceramic ya uchi amagwiritsidwa ntchito makamaka posinthana kutentha. Mpweya wotentha kwambiri ukadutsa mu chobwezeretsanso ceramic ya uchi, kutentha kumasamutsidwira ku thupi losungiramo kutentha lokha. Pambuyo pake, mpweya watsopano ukafunika kutenthedwa, kutentha komwe kumasungidwa mu chobwezeretsanso kutentha kumatulutsidwa ndikusamutsidwira ku mpweya wozizira womwe ukuyenda mosiyana ndi ma pores. Panthawiyi, mpweya wothamanga umalowa mwachangu umathandiza kusinthana kutentha bwino, zomwe zimapangitsa kuti mphamvu zigwiritsidwe ntchito bwino komanso kulola mpweya watsopano kugwira ntchito ndi mphamvu zochepa.
- Kapangidwe kake ndi kachidutswa ka ceramic ka uchi wozungulira, pogwiritsa ntchito zipangizo zatsopano zokhala ndi kuchuluka kwa sayansi komanso mawonekedwe apadera. Ukadaulo wopangira zinthu zopangidwa ndi extrusion umapangidwa ndi kutentha kwambiri.
- 1. Kuphimba ndi chophimba choletsa nkhungu ndi chosanyowa kungalepheretse kutentha kwambiri m'nyumba ndi kusonkhanitsa nkhungu. 2. Kubwezeretsanso mamolekyu amadzi kuchokera mumlengalenga, kutentha kosalekeza kwa chinyezi. 3. Kutsuka kosavuta popanda kuipitsa kwachiwiri komanso nthawi yayitali yogwira ntchito
- 1. Mphamvu zimatha kuchotsedwa mu mpweya wotulutsa utsi kuti zipereke mpweya wotenthetsera kapena woziziritsa. 2. Kusunga ndi kutulutsa kutentha bwino ndi 97%, ndipo kusinthana ndikokwanira.
- 1. Ndi mphamvu yoyamwa kutentha kwambiri, kusungira, ndi kutulutsa, monga maziko osinthira kutentha kwathunthu, imakhala ndi ntchito yobwezeretsa mphamvu. 2. Kuchuluka kwa kuchira kutentha kumafika pa 97%.
Amagwiritsidwa ntchito kwambiri m'maofesi, masukulu ndi m'malo opezeka anthu ambiri, ndipo amagwirizana ndi mpweya wokwanira m'malo akuluakulu. Makina okonzedwa bwino amatha kuyeretsa mpweya mkati mwa mtunda wa makilomita 2.5, zomwe zikusonyeza kuti mpweya ukhoza kukwera m'madera osiyanasiyana.
Mu mafakitale, amaphatikizidwa mu makina a mpweya wabwino wa fakitale okhala ndi ma VOC ambiri, kusefa tinthu tating'onoting'ono ndikuwononga mpweya woipa kudzera muzochita zoyambitsa, zomwe zimagwiritsidwa ntchito m'mafakitale a mankhwala ndi zamagetsi kuti azitha kuwongolera mpweya woipa kawiri.
