Zida zopangira mchere zimachitika mosavuta zomwe zimachitika m'zinthu zoyipa chifukwa cha moyo, kusiyanitsa ndi zinthu zina. Zina mwazinthu zachilengedwezi ndizovuta kukhala ndi madzi, ndipo nthawi zina pamakhala mpweya, kuzipindika komanso kutseka.
2. Chida chapansi sichinafanane:
Zofananira za thupi ndi glaze zitha kufotokozedwa kuchokera pazinthu zitatu: kufananiza mitundu yothamanga, kuyanika ndi kuwombera mofatsa, ndi kutukuka kofananira. Tiyeni tisanthule onse ndi m'modzi:
1) kuwombera mafayilo ofananira
Pakutentha kwa thupi ndi glaze, kusintha kwamankhwala kwamphamvu, monga: ma volalishing yamadzi oyeserera;
② 200-118 Madigiri a Celsius madzi akusintha pakati pa zigawo ③ 30-50 Kuwonongeka kwa mpweya, mpweya kupatula ⑦ 700 digiri Celsius kuti apange slikari yatsopano komanso magawo ovuta a silika.
Kutentha pamwambapa kumangogwiritsidwa ntchito monga kuwerengera komwe kumangochitika, chifukwa gawo la zinthu zathu zikafika pansi, ndipo, kuti muchepetse mtengo wake. Chifukwa chake, kwa matayala a ceramic, kutentha kolingana kutentha kudzachedwetsanso kuyankha mwachangu, ndipo ngakhale atangotulutsa zofooka zosiyanasiyana. Kuphika dumplings, kuti awapangitse kuphika mwachangu, tiyenera kuyesetsa pakhungu ndikubzala khungu, ndikupanga zocheperako zophika, etc. ndizowona kwa matailosi a ceramic. Kuwotcha, kupatulira kwa thupi, kuwombera kwambiri kuwombera ndi kupitilira apo. Ubale pakati pa thupi ndi glaze ndizofanana ndi mtundu wa atsikana. Iwo amene adawona zodzoladzola za atsikana sayenera kuvuta kumvetsetsa chifukwa chake pali zikondwerero zapansi ndi zikondwerero zapamwamba. Cholinga chachikulu cha zodzoladzola sikuti ndikubisala choyipa ndikukongoletsa! Koma ngati mwataya thukuta pang'ono, nkhope yanu idzabenidwa, ndipo mutha kukhala osagwirizana. Zomwezi ndizowona kwa matayala a ceramic. Adawotchedwa chifukwa cha chitsime choyambirira, koma ma pieles adawonekera mwangozi, ndiye chifukwa chiyani zodzolatch zimasamala za kupuma ndikusankha mitundu yosiyanasiyana ya khungu? Zodzikongoletsera zosiyanasiyana, zowoneka bwino kwambiri, za matupi osiyanasiyana, timakhalanso ndi zigawezi zozizwitsa, zidzakhala bwino kugwiritsa ntchito zitsulo zochulukirapo ngati mpweya wabwino wokhala ndi carbonate. Ngati thupi lobiriwira latha kale, gwiritsani ntchito zomangira zambiri kapena kuyambitsa ma stalent alkaline alkaline dziko lapansi ndi zida zosakanikirana. Mfundo yotopetsa ndi iyi: Kutentha kotopetsa kwa thupi lobiriwira nthawi zambiri kumakhala kotsika kuposa kwa glaze, kotero kuti malo owoneka bwino ndi omwe amatulutsidwa, koma ndizovuta kuzisintha bwino.
2) Kuyanika ndi kuwombera kofananira
Aliyense amavala zovala, ndipo ayenera kukhala omasuka, kapena ngati simungatsegulidwe pang'ono, ndipo malo osokosera adzatsegulidwa, ndipo kunyezimira kwa thupi kuli ngati zovala zomwe timavala, ndipo ziyenera kukhala bwino! Chifukwa chake, zouma za glaze zikuyeneranso kufanana ndi thupi lobiriwira, ndipo siziyenera kukhala zazikulu kapena zazing'ono kwambiri, ngakhale ming'alu yomalizidwa idzawonekera pakuyanika, ndipo njerwa yomalizidwa ikhala ndi zolakwika. Zachidziwikire, kutengera zokumana nazo ndi luso la ogwira ntchito kwambiri omwe akukhudzidwa panobe vuto linalake, ndipo onse olakwa nawonso amakhalanso abwino kwambiri chifukwa cha mafakitale omwe ali ndi mafakitale ochulukirapo.
3) Kuchulukitsa kogwirizana
Nthawi zambiri, kukula kwa thupi lobiriwira kuli kokulirapo kuposa kwa glaze, ndipo glaze amapanikizika kwambiri pambuyo powombera thupi, kotero kuti sizophweka. Ichi ndi chiphunzitso chomwe tiyenera kuphunzira tikamaphunzira zitsulo. Masiku angapo apitawo mzanga wandifunsa kuti: Chifukwa chiyani kukula kwa glaze ndikokulirapo kuposa mthupi, kotero kuti mawonekedwe a njerwa azikopedwa, koma mawonekedwe a njerwa ndi opindika? Ndizomveka kunena kuti atatenthedwa ndi kukulira, glaze ndi yayikulu kuposa maziko ndipo amapindika, ndipo glaze ndi yocheperako ndipo yakhazikika ...
Sindikufulumira kupereka yankho, tiyeni tiwone zomwe zolimba za kuwonjezeka kwa mafuta ndi. Choyamba, ziyenera kukhala mtengo. Kodi ndi chiyani? Ndi mtengo wa kuchuluka kwa chinthu chomwe chimasintha ndi kutentha. Eya, popeza imasintha ndi "kutentha", kumasintha pomwe kutentha kumatuluka ndikugwa. Kuchulukitsa kwa mafuta opatsa thupi nthawi zambiri kumayitanitsa ceramic kwenikweni ndi kokwanira. Kuchulukitsa kwa kukula kwa kuchuluka kwa kuchuluka kwa kuchuluka kwa kuchuluka kwakukulitsa kwa kukula kwa mzere, komwe ndi katatu kukula kwa mzere. Kukula kokwanira nthawi zambiri kumakhala ndi malo, ndiye kuti, "m'njira inayake yotentha". Mwachitsanzo, kodi mtengo wake ndi wotani madigiri a 20400 Celsius wamkulu? Ngati mukuumirira kukulitsa mtengo wa madigiri 400 mpaka 600, palibe lingaliro loyambirira kufanizira.
Pambuyo pomvetsetsa lingaliro la kuchuluka kwakukulitsa, tiyeni tibwererenso ku mutu woyambayo. Atatu atatenthedwa mumkono, ali ndi magawo onse komanso comerane. Tisaganizire zosintha mu kutentha kwambiri chifukwa cha kuwonjezeka kwa mafuta komanso kuphatikizidwa kale. Chifukwa chiyani? Chifukwa, kutentha kwambiri, thupi lonse lobiriwira komanso glaze ndi pulasitiki. Kuti athetse mosapita m'mbali, ndi ofewa, ndipo mphamvu yokoka ndi yayikulu kuposa kusokonezeka kwawo. Moyenera, thupi lobiriwira limawongoka ndi lowongoka ndipo lowongoka, ndipo kuchuluka kwa kukula kuli ndi phindu laling'ono. Pambuyo pa matanga a ceramic atadutsa gawo la kutentha kwambiri, imazizira kuzizira kwambiri komanso kuzizira pang'onopang'ono, ndipo matayala a ceramic amakhala cholimba kuchokera ku pulasitiki. Kutentha kumachepa, voliyumu imachepa. Zachidziwikire, chokulirapo chokwanira, chokulirapo kwa shrinkage, ndi chocheperako chokwanira, chocheperako chofananira. Pamene kukula kwa thupi ndi kwakukulu kuposa kwa glaze, thupi limasanduka kwambiri kuposa glaze nthawi yozizira, ndipo njerwayo yapindika; Ngati kukula kwa thupi ndi kocheperako kuposa kwa glaze, thupi limasanduka lopanda glaze panthawi yozizira. Ngati pali njerwa zambiri, njerwa zidzaukitsidwa, motero sizovuta kufotokoza zomwe zili pamwambapa!
