Kutsuka Makina Otsukira Zitsulo: Komwe Kumatenga Nthawi Yaitali—Mabakuli a Ceramic kapena Mabakuli a Glass

Popeza tinali ndi makina ochapira mbale kunyumba, nthawi zambiri ndimafunsidwa funso lomweli: "Pakati pa mbale zadothi ndi mbale zagalasi, ndi iti yomwe imasunga bwino mu makina ochapira mbale?" 

Yankho lake likhoza kukhala losiyana ndi zomwe mukuyembekezera. 

Mabakuli a Galasi: Malangizo Otetezera Chotsukira Mbale 

Anthu ambiri amakhulupirira kuti mbale zagalasi zimakhala zoyera komanso zowala, kotero zidzatuluka zoyera komanso zokongola zikatsukidwa mu chotsukira mbale. Zoonadi, ogwiritsa ntchito ena achita izi. 

adanenanso kuti magalasi awo amatuluka "onyezimira ngati atsopano, opanda madzi." Komabe, kaya galasi ndi lotetezeka pa chotsukira mbale zimadalira kwambiri zinthu zake ndi njira yopangira. 

Magalasi osapsa ndi kutentha (monga galasi lopaka mafuta ambiri) nthawi zambiri amatha kutsukidwa ndi makina, koma ndi bwino kusunga kutentha pakati pa 60–70°C ndikupewa kuiyika pa 

Kauntala yozizira nthawi yomweyo mukatsuka, chifukwa kusiyana kwakukulu kwa kutentha kungayambitse ming'alu. Galasi wamba la soda-laimu sililimba—pambuyo potsuka kangapo kotentha, ming'alu yaying'ono ingabuke. 

Chodabwitsa kwambiri n'chakuti, mapangidwe a tebulo lagalasi ndi "malo ovuta kwambiri." Mapangidwe ena amaoneka oyera kumbuyo akamawonedwa kuchokera mkati, zomwe zimasonyeza kuti 

Ndi zomata chabe zomwe zimatuluka pansi pa madzi amphamvu. Magalasi kapena mapatani achilengedwe okha omwe ali mkati mwa galasi lokha ndi omwe amatha kupirira kutsukidwa ndi makina. 

Kuphatikiza apo, magalasi ena amitundu yosiyanasiyana amataya kuwala kwawo pang'onopang'ono akamatsukidwa mobwerezabwereza. Ngakhale kuti magalasi savutika ndi kuphulika kwa glaze monga momwe zimakhalira ndi zinthu zadothi, koma kufooka kwake 

kukhala osamala ndi kusintha kwa kutentha, zotsatira zake, ndi kukokoloka kwa kapangidwe kake. 

Mbale ya Ceramic: Chinsinsi Chake Mu Ukadaulo Waluso 

Mkhalidwe ndi mbale za ceramic zogulitsa ku China ndi zovuta pang'ono. Poyerekeza ndi galasi, zoumba zadothi zokha sizimatentha kwambiri ndipo nthawi zambiri zimatha kuyikidwa 

mu makina otsukira mbale. Komabe, ngati zingapirire kutsukidwa zimadalira makamaka njira zokongoletsera zomwe zimagwiritsidwa ntchito pamwamba pa ceramic. 

Zokongoletsera zomwe zili pansi pa glaze zimakhala zotetezeka. Pambuyo poti kapangidwe kake kajambulidwa pa thupi la ceramic losayaka moto, chimayikidwa pamwamba pake ndi glaze yowonekera bwino kenako n’kuwotchedwa kutentha kwambiri. 

pakati pa 1200°C ndi 1400°C, kutseka kwathunthu kapangidwe kake pansi pa glaze. Pamwamba pake ndi posalala komanso mofanana, osagonjetsedwa ndi alkali, kuwonongeka, ndi kutentha kwambiri, ndipo sizingachitike. 

kufinya kapena kutulutsa zinthu zovulaza ngakhale mutatsuka mbale mobwerezabwereza. 

Kukongoletsa kowala kwambiri ndi kosiyana. Mapangidwe ake amaikidwa pamwamba pa porcelain yomwe yayaka kale kenako n’kukhazikika kudzera mu kutentha kochepa, zomwe zimasiya utoto. 

Kuwonekera mwachindunji pamwamba, zomwe zimapangitsa kuti khungu lizioneka lokongola likakhudzidwa. Kutsuka mobwerezabwereza ndi madzi amphamvu komanso sopo wa alkaline kungayambitse mosavuta mawonekedwewo 

kuti ziume kapena kung'ambika. Ogwiritsa ntchito ena anena kuti pa porcelain yowoneka bwino komanso yokhala ndi mapatani, mikwingwirima imawonekera kwambiri pakapita nthawi. 

Vuto lina lofala ndi mbale zophikira zokhala ndi m'mphepete mwa golide kapena wakuda. Kaya ndi zachitsulo kapena ayi, chidutswa chilichonse chokhala ndi chokongoletsera chachitsulo m'mphepete mwake chidzatha pambuyo pongogwiritsa ntchito makina ochapira mbale pang'ono, 

ndipo zingachotsedwe kwathunthu posamba mobwerezabwereza. Ndi bwino kutsuka mbale zamtunduwu ndi manja. 

Ndi iti yomwe ndi yolimba kwambiri? 

Ponena za kapangidwe ka zinthu, zoumba zadothi zimakhala zolimba komanso zotetezeka kuposa galasi. Chofooka cha zoumba zadothi chili mu "mapeto ake," pomwe zagalasi ndi 

"kusiyana kwa kutentha ndi zotsatira zake." 

Ngati luso loyenera lasankhidwa, lapamwamba kwambiri mbale za porcelain zosaphimbidwa ndi glaze zopangidwa kuchokera ku China nthawi zambiri zimatha kutsukidwa bwino mu chotsukira mbale. Pamene mbale zagalasi 

tulukani mowala komanso mokongola, Zinthu zawo zimakhala zofooka kwambiri kuposa zadothi, zomwe zimafuna chisamaliro chapadera pa kutentha ndi malo ake. 

Kuti mugwiritse ntchito mosavuta komanso molimba, sankhani mbale zadothi zotentha kwambiri zomwe sizimapsa ndi glaze zokhala ndi malo osalala komanso opanda mapatani okwezeka kapena zokongoletsera zagolide. Ngati mumakondadi mbale zagalasi, 

Sankhani magalasi okhala ndi borosilicate yambiri, pewani omwe ali ndi zilembo, ndipo nthawi zonse muzitsuke pang'onopang'ono.
