2. Isiseko seglaze asihambelani kakuhle:
Ukumataniswa komzimba kunye ne-glaze kunokuxoxwa kwimiba emithathu: ukuhambelana noluhlu lokukhupha umbhobho, ukomisa kunye nokudubula ukuhambelana kwe-shrinkage, kunye nokwandisa i-coefficient yokulinganisa. Masizihlalutye nganye nganye:
1) Ukudubula isithuba sokukhupha isithuba esihambelanayo
Ngexesha lokufudumeza umzimba kunye ne-glaze, uchungechunge lotshintsho lomzimba kunye neekhemikhali luya kwenzeka ngokunyuka kwamaqondo obushushu, njengale: i-adsorption yamanzi, ukukhutshwa kwamanzi ekristale, ukubola kwe-oxidative yezinto eziphilayo kunye nokubola kweeminerali ezingaphiliyo, njl. ., ukusabela okuthe ngqo kunye nokubola Ubushushu buye bavavanywa ngabaphengululi abaphezulu, kwaye bukhutshelwa ngolu hlobo lulandelayo ukuze lubhekiselele ① Ubushushu begumbi -100 degrees Celsius, amanzi adsorbed aguqukayo;
② 200-118 degrees Celsius ukuphuphuma kwamanzi phakathi kwamagumbi ③ 350-650 degrees Celsius kutshisa izinto eziphilayo, sulfate kunye nokubola sulfide ④ 450-650 degrees Celsius recombination crystal, ukususwa kwamanzi ekristale ⑤ 573 degrees Celsius 8 ukuguqulwa quartz 0⑥5 umthamo quartz 0-99 ukuguqulwa iCelsius calcite, ukubola kwedolomite, igesi Ungabandakanyi ⑦ 700 degrees Celsius ukwenza izigaba zesilicate ezitsha kunye nezintsonkothileyo zesilicate.
Iqondo lokushisa elihambelanayo lokubola linokusetyenziswa kuphela njengesalathiso kwimveliso yokwenyani, kuba ibakala lemathiriyeli yethu ekrwada liya liphantsi naphantsi, kwaye, ukuze kuncitshiswe iindleko zemveliso, umjikelo wokudubula kwiziko uya usiba mfutshane kwaye umfutshane. Ke ngoko, kwiithayile ze-ceramic, iqondo lokushisa elihambelanayo lokubola liya kulibaziseka ekuphenduleni ukutshisa ngokukhawuleza, kunye nokukhupha okugxininisiweyo kwindawo yobushushu obuphezulu kuya kubangela iziphene ezahlukeneyo. Ukupheka amadombolo, ukwenzela ukuba bapheke ngokukhawuleza, kufuneka sisebenze nzima eluswini kunye nokugxumeka, wenze ulusu lube luncinci, wenze izinto ezincinci okanye ufumane izinto ezilula ukupheka, njl njl. Kuyafana nakwiithayile ze-ceramic. Ukutshisa, ukunciphisa umzimba, ukudubula kwe-glaze ububanzi kunye nokunye. Ubudlelwane phakathi komzimba kunye ne-glaze bufana ne-makeup yamantombazana. Abo baye babona izimonyo zamantombazana akufanele kube nzima ukuqonda ukuba kutheni kukho i-glazes ephantsi kunye ne-glazes ephezulu emzimbeni. Eyona njongo ye-makeup ayikuko ukufihla ububi kwaye Uyenze ibe buhle! Kodwa ukuba ubila kancinci ngempazamo, ubuso bakho buya kuba nebala, kwaye unokuba nokwaliwa. Kukwanjalo nangeethayile zeceramic. Zazitshiswe kakuhle kwasekuqaleni, kodwa imingxunya yavela ngempazamo, kutheni ke izithambiso zithathela ingqalelo ukuphefumla kwaye zikhethe ngokweentlobo ezahlukeneyo zolusu? Izithambiso ezahlukeneyo, enyanisweni, iiglazi zethu ziyafana, kwimizimba eyahlukeneyo, sinazo neeglazes ezahlukeneyo zokuziqhelanisa nazo, iithayile zeceramic zagxothwa kanye, ndikhankanyile kwinqaku elandulelayo: Kuya kuba ngcono ukusebenzisa izixhobo ezingaphezulu ukuba umoya ifike emva kwexesha kwaye yazisa i-bivalent alkaline yomhlaba isinyithi kunye ne-carbonate.

Umgaqo wokuphelelwa ngamandla kukuba: iqondo lobushushu elidiniweyo lomzimba oluhlaza lisezantsi kakhulu kunolo lweglaze, ukuze indawo ekhazimlayo ibentle ngokuqinisekileyo emva kokuba irhasi engezantsi ikhutshiwe, kodwa kunzima ukuyifumana kwimveliso yokwenyani, kwaye indawo ethambileyo yeglaze kufuneka ibuyiselwe umva ngokufanelekileyo ukuze kube lula ukukhupha umzimba.
2) Ukomisa kunye nokudubula ukuhambelana kwe-shrinkage
Wonke umntu unxiba iimpahla, kwaye kufuneka akhululeke ngokwentelekiso, okanye ukuba kukho ukungakhathali okuncinci, imithungo iya kuvulwa, kwaye ukukhazimla komzimba kufana nempahla esiyinxibayo, kwaye ifanele ilingane kakuhle! Ngoko ke, ukuncipha kwe-glaze kufuneka kuhambelane nomzimba oluhlaza, kwaye akufanele kube mkhulu kakhulu okanye kuncinci, ngaphandle koko ukuqhekeka kuya kubonakala ngexesha lokumisa, kwaye isitena esigqityiweyo siya kuba neziphene. Ngokuqinisekileyo, ngokusekelwe kumava kunye nenqanaba lobugcisa labasebenzi be-glaze bangoku Kuthiwa le nto ayisekho ingxaki enzima, kwaye i-debuggers ngokubanzi nayo ilungile kakhulu ekubambeni udongwe, ngoko ke le meko ingasentla ayibonakali rhoqo, ngaphandle kokuba ezi ngxaki zingasentla zenzeka kwezinye iifektri ezineemeko zemveliso eziqatha.
3) Ukwandiswa kwe-coefficient ehambelanayo
Ngokuqhelekileyo, i-coefficient yokwandiswa komzimba oluhlaza mkhulu kancinane kune-glaze, kwaye i-glaze iphantsi koxinzelelo loxinzelelo emva kokudubula kumzimba oluhlaza, ukwenzela ukuba ukuzinza kwe-thermal ye-glaze kube ngcono kwaye akukho lula ukuqhekeka. . Le yithiyori ekufuneka siyifunde xa sifunda iisilicates. Kwiintsuku ezimbalwa ezidlulileyo umhlobo wandibuza: kutheni i-coefficient yokwandiswa kwe-glaze inkulu kunomzimba, ngoko ke ukumila kwezitena kuya kuguqulwa, kodwa i-coefficient yokwandisa i-glaze incinci kuneyomzimba, ngoko isitena. imilo igophe? Kunengqiqo ukutsho ukuba emva kokufudunyezwa kunye nokwandiswa, i-glaze inkulu kunesiseko kwaye igobile, kwaye i-glaze incinci kunesiseko kwaye ijikelezwe ...
Andingxami ukunika impendulo, makhe sijonge ukuba yintoni i-coefficient yokwandiswa kwe-thermal. Okokuqala, kufuneka ibe lixabiso. Luhlobo olunjani lwexabiso? Lixabiso lomthamo wezinto eziguqukayo ngobushushu. Ewe, ekubeni iguquka "ngobushushu", iya kutshintsha xa iqondo lokushisa liphakama kwaye liwa. I-coefficient yokwandiswa kwe-thermal esihlala siyibiza ngokuba yi-ceramics eneneni yi-coefficient yokwandisa umthamo. I-coefficient yokwandiswa komthamo ngokuqhelekileyo ihambelana ne-coefficient yokwandiswa komgca, malunga namaxesha angama-3 ukunyuswa komgca. I-coefficient yokwandisa imilinganiselo ngokubanzi inesiseko, oko kukuthi, "kwiqondo elithile lobushushu". Umzekelo, luhlobo luni lwegophe elixabisa i-20-400 degrees Celsius ngokubanzi? Ukuba uyagxininisa ekuthelekiseni ixabiso lee-degrees ezingama-400 ukuya kuma-600 Kambe ke, akukho sigqibo sicacileyo sinokufikelelwa kuthelekiso.
Emva kokuqonda ingcamango yokwandisa i-coefficient, masibuyele kwisihloko sokuqala. Emva kokuba iithayile zifudunyezwe kwi-oven, zinezigaba zombini zokwandisa kunye nokunciphisa. Masingacingi ngotshintsho kwindawo yobushushu obuphezulu ngenxa yokwandiswa kwe-thermal kunye nokucutha ngaphambili. Ngoba? Ngenxa yokuba, kwiqondo lokushisa eliphezulu, zombini umzimba oluhlaza kunye ne-glaze yiplastiki. Ngokucacileyo, zithambile, kwaye impembelelo yomxhuzulane inkulu kunoxinzelelo lwazo. Ngokufanelekileyo, umzimba oluhlaza uqondile kwaye uthe tye, kwaye i-coefficient yokwandisa inefuthe elincinci. Emva kokuba i-tile ye-ceramic idlula kwicandelo lobushushu obuphezulu, ipholisa ngokukhawuleza kwaye ipholile ngokukhawuleza, kwaye i-tile ye-ceramic iba nzima kumzimba weplastiki. Njengoko iqondo lokushisa liyancipha, umthamo uyancipha. Ngokuqinisekileyo, inkulu i-coefficient yokwandisa, i-shrinkage enkulu, kwaye incinci i-coefficient yokwandisa, incinci i-shrinkage ehambelanayo. Xa i-coefficient yokwandiswa komzimba inkulu kune-glaze, umzimba uyancipha ngaphezu kwe-glaze ngexesha lokupholisa, kwaye isitena sigobile; ukuba i-coefficient yokwandisa umzimba incinci kune-glaze, umzimba uyancipha ngaphandle kwe-glaze ngexesha lokupholisa. Ukuba kukho izitena ezininzi, izitena ziya kuguqulwa, ngoko akunzima ukucacisa le mibuzo ingentla!
