Iri pamusoro rinoenderana tembiricha yekuora inogona kungoshandiswa sereferensi mukugadzirwa chaiko, nekuti giredhi remidziyo yedu iri kuderera nekudzikira, uye, kuitira kudzikisa mutengo wekugadzira, kutenderera kwekupisa kwemoto kuri kuita kupfupika nekupfupika. Naizvozvo, kune mataira eceramic, iyo inoenderana decomposition reaction tembiricha inozononokawo mukupindura nekukurumidza kupisa, uye kunyange yakadzika kupera munzvimbo yekushisa yepamusoro inokonzeresa kukanganisa kwakasiyana. Kubika dumplings, kuitira kuti vabike nokukurumidza, tinofanira kushanda nesimba pamusoro ganda uye stuffing, kuita ganda mutete, kuita shoma stuffing kana kuwana zvimwe stuffing zviri nyore kubika, etc. Ndizvo zvakafanana kune zvedongo mataira. Kupisa, kuonda muviri, glaze firing range richiwedzera zvichingodaro. Hukama huripo pakati pemuviri nekupenya hwakafanana nekugadzirwa kwevasikana. Avo vakaona kugadzirwa kwevasikana havafaniri kuva vakaoma kunzwisisa kuti nei kune pasi glazes uye kumusoro glazes pamuviri. Chinangwa chakakosha chekugadzira hachisi kuvanza kushata uye Kuishongedza! Asi kana ukaita dikita zvishoma netsaona, chiso chako chinenge chakasviba, uye unogona kunge uchirwara. Izvi zvakafanana kune mataira e ceramic. Ivo pakutanga vakapiswa zvakanaka, asi pinholes akaonekwa netsaona, saka sei zvizorwa zvichiteerera kufema uye kusarudza zvinoenderana nemhando dzakasiyana dzeganda? Zvizoro zvakasiyana-siyana, chaizvoizvo, glazes yedu yakafanana, kune miviri yakasiyana, tinewo mazhenje akasiyana-siyana kuti aenderane navo, matairi edomi akadzingwa kamwe chete, ini ndakataura munyaya yapfuura: Zvichava nani kushandisa zvinhu zvakawanda zvakasvibiswa kana mhepo yakanonoka uye kuunza bivalent alkaline pasi simbi ne carbonate. Kana muviri wakasvibira wapera kare, shandisa mamwe mafrits kana kuunza divalent alkaline pasi simbi nezvinhu zvine kurasikirwa kushoma. Musimboti wekunetesa ndewekuti: tembiricha inonetesa yemuviri wakasvibira kazhinji yakadzikira pane iyo glaze, zvekuti iyo yakapenya inoratidzika yakanaka mushure mekunge gasi riri pazasi raburitswa, asi zvinonetsa kuwana mukugadzirwa chaiko, uye nzvimbo yekupfavisa yekupenya inofanirwa kudzoserwa kumashure kuti ifambise kupera kweMuviri.
2) Kuomesa uye kupfura shrinkage kuenzanisa
Wese munhu anopfeka hanzu, uye dzinofanira kunge dzakagadzikana, kana paine kusava nehanya kushoma, misono ichavhurwa, uye kupenya kwemuviri kwakangofanana nembatya dzatinopfeka, uye dzinofanira kukwana zvakanaka! Nokudaro, kuomeswa kwe shrinkage ye glaze kunofanirawo kufanana nemuviri wakasvibirira, uye haifaniri kunge yakakura kana kuti duku, kana zvisina kudaro kuputika kuchaonekwa panguva yekuoma, uye chidhinha chakapedzwa chichava nezvikanganiso. Ehe, zvichibva pane ruzivo uye tekinoroji yevashandi vezvino glaze Zvinonzi iri harisi dambudziko rakaoma zvakare, uye vagadziri vese vakanaka kwazvo kubata ivhu, saka mamiriro ari pamusoro haaonekwe kazhinji, kunze kwekunge matambudziko ari pamusoro aitika mune mamwe mafekitori ane hutsinye hwekugadzira mamiriro.
3) Kuwedzera coefficient kuenzanisa
Kazhinji, iyo yekuwedzera coefficient yemuviri wegirinhi yakakura zvishoma pane iyo glaze, uye glaze inoiswa pasi pekumanikidzwa kwekumanikidza mushure mekupfura pane yakasvibira muviri, kuitira kuti kugadzikana kwekupisa kwe glaze kuve nani uye hazvisi nyore kuputika. Iyi ndiyowo dzidziso yatinofanira kudzidza patinodzidza silicates. Mazuva mashoma apfuura shamwari yakandibvunza: nei kuwedzera kweiyo glaze yakakura kupfuura iyo yemuviri, saka chimiro chezvidhinha chichave chakakanganiswa, asi iyo yekuwedzera coefficient ye glaze idiki pane yemuviri, saka chimiro chezvidhinha chakakombama? Zvine musoro kutaura kuti mushure mekupisa nekuwedzerwa, glaze yakakura kupfuura chigadziko uye yakakomberedzwa, uye glaze idiki pane hwaro uye yakamonyoroka…
Handisi kukurumidza kupa mhinduro, ngatitarisei kuti coefficient yekuwedzera kwekushisa chii. Chokutanga pane zvose, inofanira kuva yakakosha. Kukosha kwerudzii? Ndiko kukosha kwehuwandu hwechinhu chinoshanduka nekupisa. Zvakanaka, sezvo ichichinja ne "temperature", inoshanduka kana kutonhora kuchikwira nekudonha. Iyo yekupisa yekuwedzera coefficient yatinowanzo kudaidza kuti ceramics ndiyo chaiyo iyo vhoriyamu yekuwedzera coefficient. Iyo coefficient yekuwedzera vhoriyamu inowanzoenderana neiyo coefficient ye mutsara wekuwedzera, iyo ingangoita 3 nguva yekuwedzera kwemutsara. Iyo yakayerwa yekuwedzera coefficient kazhinji ine nzvimbo, kureva, "mune imwe tembiricha yemhando". Semuenzaniso, rudzii rwecurve kukosha kwe20-400 degrees Celsius kazhinji? Kana iwe ukaomerera pakuenzanisa kukosha kwe400 madhigirii kusvika 600 madhigirii Chokwadi, hapana mhedziso ine chinangwa inogona kutorwa kubva pakuenzanisa.
Mushure mekunzwisisa pfungwa yekuwedzera coefficient, ngatidzokerei kune yekutanga musoro. Mushure mekunge mataira apiswa muchoto, ane ese ari maviri ekuwedzera uye kupesana matanho. Ngatiregei kufunga nezve shanduko munzvimbo yepamusoro tembiricha nekuda kwekuwedzera kwekupisa uye kuderera zvisati zvaitika. Sei? Nekuti, pakupisa kwakanyanya, muviri wakasvibira uye glaze ipurasitiki. Kutaura zvakajeka, ivo vakapfava, uye pesvedzero yesimba rinokwevera zvinhu pasi ihuru kupfuura kukakavara kwavo vamene. Zvakanaka, muviri wakasvibirira wakatwasuka uye wakatwasuka, uye coefficient yekuwedzera haina mhedzisiro. Mushure mokunge tile yekeramic inopfuura nepamusoro-soro chikamu, inopinda nekukurumidza kutonhora uye kunonoka kutonhora, uye tile yekeramic inova yakaoma kubva mumuviri wepurasitiki. Sezvo tembiricha inoderera, vhoriyamu inoderera. Ehe, iyo yakakura coefficient yekuwedzera, iyo yakakura shrinkage, uye madiki ekuwedzera coefficient, madiki anowirirana shrinkage. Kana iyo yekuwedzera coefficient yemuviri yakakura kupfuura iyo glaze, muviri unoderera kupfuura glaze panguva yekutonhora, uye chidhinha chakakombama; kana chiyero chekuwedzera chemuviri chiri chidiki pane icho che glaze, muviri unoderera pasina glaze panguva yekutonhora. Kana pane zvidhinha zvakawanda, zvidhinha zvichasimudzwa, saka hazvisi zvakaoma kutsanangura mibvunzo iri pamusoro apa!
