Inqubo yokwenza i-Porcelain

Ukutshalwa okujulile kwensimu yasendlini ye-ceramic

Ukwazi izinqubo ezahlukene zobuchwepheshe kusenza sibe umholi kulo mkhakha

Inqubo yokwenza i-porcelain ngokuvamile ihlanganisa lezi zinyathelo ezilandelayo:

Ukwakhiwa nokukhiqizwa kwemodeli ye-3D:

Okokuqala yenza ukwakheka komkhiqizo, bese wenza imodeli, ezokhuphuka ngo-14% ngenxa yokuncipha ngemuva kwenqubo yokudubula. Isikhunta se-plaster (isikhunta esikhulu) sibe sesenzelwa imodeli.

Ukwenza i-Mold:

Uma ukubunjwa kokuqala kwesikhunta esiyinhloko kuhlangabezana nezidingo, isikhunta esisebenzayo senziwe.

Thela ku-plaster mold:

Thela i-ceramic slurry ewuketshezi esikhunjini se-plaster. I-gypsum imunca omunye umswakama odongeni, yakhe udonga noma "umbungu" womkhiqizo. Ubukhulu bodonga bomkhiqizo bulingana ngokuqondile nesikhathi impahla ekubunjweni. Ngemva kokufinyelela ubukhulu bomzimba obufunayo, i-slurry ithululwa. I-Gypsum (i-calcium sulfate) inikeza umkhiqizo we-limestone futhi iwusiza ukuba uqine ube esimweni lapho ungasuswa khona esikhunjeni.

Ukomisa nokunquma:

Umkhiqizo oqediwe uyomiswa futhi uthungelwe kanye nokungapheleli kunqunywe. Ukudubula kanye nokucwebezela: Umkhiqizo ubaswa ezingeni lokushisa elingu-950°C. Umkhiqizo oshisiwe ube usucwebezeliswa futhi ushiswe futhi esithandweni esingu-1380 ° C, ngokuvamile endaweni enciphisayo.

Umhlobiso:

Ukuhlotshiswa kwemikhiqizo emhlophe kusetshenziswa izibala zokuhlobisa ezicwebe kakhulu, izimibalabala eziqukethe izinsimbi eziyigugu njengegolide noma iplatinamu, nosawoti wokuhlobisa (i-metal chlorides). Hlobisa ngendlela evamile futhi ubeke kuhhavini futhi, kulokhu ku-800°C.

Ukuhlola Nokuthumela:

Imikhiqizo ihlolwa ngokucophelela ngemva kokupholisa futhi ifakwe emabhokisini akhethekile okuvikela ngaphambi kokuthunyelwa. Lezi yizinyathelo ezijwayelekile zokwenza imikhiqizo ye-porcelain.
