Malingana ndi mawerengedwe ndi ziwerengero, ndondomeko yoponyera mchenga wa ceramic imafuna pafupifupi matani 0.6-1 a mchenga wokutira (pachimake) kuti apange tani imodzi ya castings. Mwanjira iyi, chithandizo cha mchenga wogwiritsidwa ntchito chakhala cholumikizira chofunikira kwambiri panjira iyi. Izi sizongofunika kuchepetsa ndalama zopangira zinthu komanso kupititsa patsogolo phindu lazachuma, komanso kufunikira kochepetsa kutulutsa zinyalala, kuzindikira chuma chozungulira, kukhala mogwirizana ndi chilengedwe, ndikupeza chitukuko chokhazikika.
Cholinga cha reclamation ya TACHIMATA mchenga ceramic ndi kuchotsa utomoni yotsalira TACHIMATA pamwamba pa mchenga njere, ndipo nthawi yomweyo kuchotsa zitsulo zotsalira ndi zosafunika zina mu mchenga wakale. Zotsalira izi kwambiri zimakhudza mphamvu ndi kulimba kwa TACHIMATA ceramic mchenga analandidwa, ndipo pa nthawi yomweyo kuonjezera kuchuluka kwa mpweya m'badwo ndi Mwina kubala zinyalala. Zofunikira zamtundu wa mchenga wobwezeredwa nthawi zambiri: kutayika pakuyatsa (LOI) <0.3% (kapena kutulutsa gasi <0.5ml/g), komanso magwiridwe antchito a mchenga wobwezeretsedwa omwe amakumana ndi index iyi mutatha kuyatsa sizosiyana kwambiri ndi mchenga watsopano.
Mchenga wokutidwa umagwiritsa ntchito thermoplastic phenolic resin ngati chomangira, ndipo filimu yake ya utomoni imakhala yolimba. Mwachidziwitso, njira zonse zotentha komanso zamakina zimatha kuchotsa filimu yotsalira ya utomoni. Kusintha kwa kutentha kumagwiritsa ntchito njira ya carbonization ya resin film pa kutentha kwakukulu, yomwe ndi njira yokwanira komanso yothandiza kwambiri yokonzanso.
Pankhani ya matenthedwe obwezeretsanso mchenga wokutira wa ceramic, mabungwe ofufuza ndi opanga ena achita kafukufuku wambiri woyesera. Pakalipano, njira yotsatirayi imakonda kugwiritsidwa ntchito. Kutentha kwa ng'anjo yowotcha ndi 700 ° C-750 ° C, ndipo kutentha kwa mchenga ndi 650 ° C-700 ° C. Njira yobwezeretsanso nthawi zambiri imakhala:
(Kugwedezeka kwamphamvu) → cholekanitsa maginito → cholekanitsa zinyalala → (chonyamulira ndowa) → (chowotchera chidebe) → chotengera mchenga chosungiramo → chotenthetsera chotenthetsera → bedi lowira → njira yochotsera fumbi → ufa woyambira mchenga → hopper Kunyamulira → kutulutsa mpweya wotuluka → kunyamula mchenga → ng'anjo yowotcha yamadzimadzi → ndowa yamchenga yapakatikati → mzere wopanga mchenga
Ponena za zida zobwezeretsa mchenga wa ceramic, kukonzanso kwamafuta kumagwiritsidwa ntchito nthawi zambiri. Magwero amagetsi amaphatikizapo magetsi, gasi, malasha (coke), mafuta a biomass, ndi zina zotero, ndi njira zosinthira kutentha zimaphatikizanso mtundu wa kukhudzana ndi mtundu wowira wa mpweya. Kuphatikiza pa makampani akuluakulu odziwika omwe ali ndi zida zotha kukonzanso zinthu, makampani ang'onoang'ono ambiri alinso ndi zida zambiri zaluso zobwezeretsanso zomwe zidamangidwa okha.
