Iindlela ezimfutshane ezi-3 zokuphucula ukunyuka kobushushu obuphezulu bezinto eziphikisayo

Ubushushu obuphezulu bepropathi ibhekisa kubudlelwane phakathi kokutshintsha kwezinto nezinto ezichasayo kunye nexesha phantsi kobushushu obuphezulu obuqhubekayo kunye nomthwalo osisigxina.

Ubomi benkonzo yee-kilns ezinobushushu obuphezulu bude iminyaka eliqela, okanye nangaphezulu kweminyaka elishumi. Ekugqibeleni, ukonakaliswa kobushushu obuphezulu bezinto ezichasayo akwenzeki ngenxa yamandla, kodwa sisiphumo seziphumo ezidibeneyo zobushushu obuphezulu, ukomelela kunye nexesha. Umzekelo, izitena zokujonga izitovu ezishushu ezitshisayo zisebenza kubushushu obuphezulu ixesha elide, ngakumbi phantsi kwesenzo somthwalo kunye nobushushu obuphezulu, izitena zithamba ngokuthe ngcembe kwaye zivelise ukujika kweplastiki, kwaye amandla abo ancipha ade aphuke. Ingqwalasela ekhethekileyo ihlawulwa kwiqondo lokushisa kunye nesakhiwo. Ubume be-inhomogeneity yesakhiwo somlilo kunye ne-deformation yeplastiki enzulu yezitena ezithile kuya kubangela ukutshatyalaliswa ngokupheleleyo kwesakhiwo somlilo.

Ke ngoko, phucula ukunganyangeki okunqabileyo kwezinto ezinqabileyo, funda utshintsho kulwakhiwo lwezixhobo ezinokwala phantsi koxinzelelo lobushushu obuphezulu; jonga umgangatho weemveliso; vavanya inkqubo yemveliso; ukuqikelela utshintsho kumthwalo weemveliso ezichasayo kusetyenziso olusebenzayo kuyilo lweziko; vavanya iimveliso Ukusebenza njalo njalo kuneentsingiselo ezibaluleke kakhulu.

Ukuthetha ngokubanzi, ukuphucula ukunganyangeki kwezinto ezinqabileyo, ikakhulu ngezi ndlela zintathu zilandelayo:

1.Zicoca izinto ezingasafunekiyo: phucula ubunyulu bempahla ekrwada okanye ucoce izinto ezingafunekiyo ukunciphisa ukungcola okunje ngezinto ezinyibilikayo eziphantsi kunye neefluxes ezomeleleyo (ezinje ngeNa2O kwizitena zodongwe, iAl2O3 kwizitena zesilica, iSiO2 kunye neCaO kwizitena zemagnesia, njl.) Umxholo wemveliso, ngaloo ndlela unciphisa umxholo wesigaba seglasi kwimveliso (le yindlela ecetyiswayo yokuphucula ukusebenza);

2. Yomeleza imatriki: yazisa ngezixhobo “ezibuyela umva zokuhamba”. Umzekelo, ubungakanani obuthile be-quartz particles bufakwa kwizithako zezitena eziphezulu zealumine. Xa izitena zealumina eziphezulu zisetyenziswa kubushushu obuphezulu, ukusabela kokudibana kwe-mullite kuyaqhubeka ukwenzeka kwi-quartz SiO2 kunye ne-Al2O3 kwizixhobo eziphezulu zealumum, kwaye inkqubo yokuphendula ihamba kunye nenqanaba elithile levolumu. Ukudumba. Iziphumo zolu lwandiso lomthamo “sisiphumo sokubuyela umva”, esinokuthi sisuse ukuhla kwesinciphiso ngexesha lokuhamba kwezinto, ngokwenjenje siphucule ukuxhathisa kwezitena eziphezulu zealumum.

3. Ukuphucula inkqubo: ukuyila ngokufanelekileyo ukubekwa kwamasuntswana kwinto yebhetshi, ukwandisa uxinzelelo lobumba lomzimba oluhlaza, ukufumana umzimba oxineneyo oluhlaza, ukunciphisa inani lembobo kwimveliso, kunye nokwandisa izinto ezifanelekileyo kwimveliso ngokuchasene nokuhamba; qulunqa inkqubo efanelekileyo yokudubula (ubushushu bokuSintering, ixesha lokubamba, ukufudumeza kunye neqondo lokupholisa), ukwenzela ukuba ukuphendula okuyimfuneko komzimba kunye neekhemikhali kwinto leyo kwenziwe ngokupheleleyo, kwaye kufunyenwe ukwakheka kwesigaba kunye nolwakhiwo olufunekayo.
