Iyiphi inqubo yokulungiselela yezinto zokwakha ze-ceramic ezithuthukile?

Inqubo yokulungiselela ama-ceramics athuthukile ikakhulukazi ifaka phakathi i-synthesis ye-powder yoqobo, ukubumba komkhiqizo, ukopisha, ukucubungula kanye nokuhlolwa. Ngaphezu kwalokho, ngokuya ngezimpawu zokubukeka kwemikhiqizo ye-ceramic, ama-ceramics athuthukile nawo angahlukaniswa ngezinto zokwakha eziqinile zobumba, izinto eziphambili ze-ceramic composite, izinto zokulungiswa ze-ceramic ezithuthukile, isibalo esilandelayo sibonisa Inqubo yokulungiselela yezinto zokwakha ze-ceramic ezithuthukile.

1. Izinto zokusetshenziswa

Ngokuvamile, bangamakhemikhali amakhemikhali noma izinto zokusetshenziswa zamakhemikhali zezimboni ezinobumsulwa obusezingeni eliphezulu obuhlanziwe futhi bucutshungulwe. Kwesinye isikhathi izinto ezikhethekile eziluhlaza nazo zingasetshenziswa, futhi ukuhlanzwa kwezinto ezingavuthiwe kwenziwa kanye nenqubo yokwenza i-powder.

2. I-Powder synthesis

I-powder ehlangabezana nezidingo (ukwakheka kwamakhemikhali, ukwakheka kwesigaba, ubumsulwa, ubungako bezinhlayiyana, ushukela, njll.) Ihlukaniswe ngezinto zokuqala zokuvuselelwa ngamakhemikhali ngokuphendula kwamakhemikhali. Indlela ye-powder synthesis ingaba yimishini yokuchotshozwa ngokuhlaziywa kwezinhlayiyana. Ingalungiswa futhi yindlela esemqoka yokuzijabulisa nokukhula kwezinhlayiya ku-Medium, eyokugcina ngokuvamile yindlela yamakhemikhali. Ukuhlangana kwezigaba ezahlukahlukene zokusabela kwamakhemikhali, izindlela ze-C Hemical zingahlukaniswa ngezindlela zesigaba se-liquid, izindlela zesigaba segesi nezindlela zesigaba eziqinile

3. Ukulungiswa kwe-powder

Uma i-synthesised powder ayihlangabezani nokuklanywa noma izidingo zenqubo elandelayo, i-powder idinga ukulungiswa. Uma i-powder ingalungile ngokwanele noma iqukethe ama-agglomerates amakhulu, i-powder idinga ukuba yindawo. Uma iqukethe ukungcola okungathandeki kwe-ionic, kungagezwa. Ukulungiswa kwe-powder kuhlanganisa nokungezelelwa kwezithasiselo ze-organic, ukulungiswa komswakama, ukugcotshwa, udaka, imfucumfucu ) nokulungiselela okumnandi) kanye nokulungiselela okumnandi, kanye nokuxova ukukwenza kufanelekile ukubumba.

4. Ukwakha

Shintsha uhlelo lokuhlakazeka (i-powder, impahla evuthayo kanye ne-slurry impahla) ibe yibhlokhi elinesimo esithile sejometri, ivolumu namandla, nangokuthi kubizwa nalutho. Ama-granular powders abunjiwe ngokucindezela owomile noma ngokucindezela okuzayo; Izinto ze-Ductile zilungele ukubumba kokubumba noma kokuhlombu; Izinto ezimnandi zibunjiwe ngokuphonswa.

5. Ukuhlekisa ngaphambi kokuthola ukona

Njengoba isidumbu esibunjiwe siqukethe inani elithile lezithasiselo ze-organic kanye ne-solvents, kudinga ukucutshungulwa ngaphambi kokuba nesono, okungukuthi, ukomisa futhi kuvutha izithasiselo ze-organic.

6. Isono

Kubhekiswa kwinqubo yokubangela izinguquko ezingokomzimba zemzimba ebunjiwe ukwenza ivolumu yalo ukuncipha nobunzima bayo ukwanda ngaphansi kokushisa okuthize kanye nengcindezi. I-SENTIGING iyisinyathelo esingukhiye ekwenziweni kwezinto zokwakha i-ceramic. Ngesono, impahla ayigcini nje ngokuba mnene, kepha futhi ithola izakhiwo ezikhethekile zemishini ezinjengamandla nezinye izakhiwo ezisebenzayo.

7. Imishini

Ubunjiniyela be-ceramics kumele bucutshungulwe ngokuya ngezidingo zamakhasimende ngaphambi kokusebenzisa. Ngenxa ye-shrinkage enkulu eyenzeka ngesikhathi senqubo yesono kunezingxenye zobumba eziluhlaza, ukuphambuka okuyisisekelo komzimba onesono kungokuhleleka kwamamilimitha noma okukhulu, okungekho okuqhubekayo okusebenzayo kuyadingeka.
