Lokhu kulinganisela phakathi kwe-porosity kanye namandla kungenye yezinto ezibalulekile okufanele zicatshangelwe ekuklanyweni

imikhiqizo yensimbi ecibilikisiwe futhi akunakwenzeka ukuyifeza ngezinqubo ezisekelwe ekuncibilikisweni.

Umbuzo 5: Ingabe ukuncibilikisa inhlabathi kunobungani nemvelo kunokuncibilikisa?

Ingabe ukuncibilikisa inhlabathi kunobungani nemvelo kunokuncibilikisa?

Ngokuvamile, yebo. Ukuhlanza kuvame ukubhekwa njengokusimeme kakhulu ngoba:

*Kudinga amazinga okushisa aphansi okucubungula

*Isebenzisa amandla amancane

*Ikhiqiza izinsalela ezincane kanye nemfucuza

*Isebenzisa ukukhiqiza okunesimo esiseduze ne-net

Izinqubo zokuncibilikisa zendabuko zidinga ukushisa okuphezulu futhi zivame ukuhilela ukwenziwa kwemishini yesibili

izinyathelo ezikhiqiza izinto ezilahliwe.

Ukusansimbi kwempuphu kuthuthukisa ukusetshenziswa kwezinto futhi kungasekela imigomo yokukhiqiza eluhlaza.

Umbuzo 6: Ingabe ukuncibilikisa kungathatha indawo yokuncibilika kuzo zonke izinhlelo zokusebenza zensimbi?

Ingabe ukuthungwa kwe-sintering kungathatha indawo yokuncibilika kuzo zonke izinhlelo zokusebenza?

Cha. Ukusinta nokuncibilikisa kufeza izidingo ezahlukene zokukhiqiza futhi kuyahambisana

kunokuba kube nokushintshana.

Ukuncibilikisa kubalulekile ku:

*Izingxenye ezinkulu zesakhiwo
*Izihlanganisi ezihlanganisiwe
*Izicelo ezidinga ukuguquguquka okuphezulu

Ukuhlanza kulungele:

*Izingxenye zokunemba
*Izingxenye ezisebenzayo ezinezimbobo
Imikhiqizo ejwayelekile enomthamo ophezulu

Ukukhetha phakathi kwazo kuncike ku-geometry, izidingo zokusebenza, kanye nemigomo yezindleko.

Q7: Iyiphi inqubo enikeza ukunemba okungcono kobukhulu?

Iyiphi inqubo enikeza ukunemba okungcono kobukhulu: ukuncibilikisa noma ukuncibilikisa?

Ukusinta ngokuvamile kunikeza ukulawula okungcono kobukhulu bezingxenye ezincane neziyinkimbinkimbi ngenxa yalokhu:

*Izikhunta eziqondile

*Ukuguquguquka okulinganiselwe ngesikhathi sokushisa

*Ukukhiqiza okunesimo esiseduze ne-net

Ukuncibilika nokusatshalaliswa kungabhekana nokuncibilika kanye nokuphambuka ngesikhathi sokuqina,

ngokuvamile kudinga imishini eyengeziwe ukuze kufezwe ukubekezelelana okuqinile.

Lokhu kwenza i-sintering ifaneleke kakhulu kuma-sensor, izingxenye zezokwelapha, kanye nezingxenye ezincane zemishini.

Umbuzo 8: Izakhiwo ezincane zihluke kanjani phakathi kwezinsimbi ezisikiwe nezincibilikisiwe?

Izakhiwo ezincane zihluke kanjani phakathi kwezinsimbi ezisikiwe nezincibilikisiwe?

Izinsimbi ezisikiwe zakhiwe yizinhlayiya zempuphu eziboshiwe ezinemingcele elawulwayo phakathi kwezinhlayiya

kanye nokuvuleka okungakhethwa. Isakhiwo sazo esincane singaklanywa ukuze kufezwe ukugeleza okuthile,

ukuhlunga, noma izakhiwo zemishini.

Izinsimbi ezincibilikisiwe ziyaqina zisuka esimweni soketshezi futhi ngokuvamile zakha okusanhlamvu okukhulu okunezakhiwo eziqhubekayo.

Nakuba lokhu kunganikeza amandla amakhulu kakhulu obuningi, akunawo ukuguquguquka kwesakhiwo se-powder metallurgy.

Lo mehluko oyisisekelo uchaza ukuthi kunganii-powder metallurgy vs ukuncibilika kwendabukokuholela ku-

ukusebenza kwezinto ezibonakalayo kanye namathuba okusebenzisa ahlukene.

Isiphetho

Ukuqonda umehluko phakathiukuncibilikisa vs ukuncibilikisaisinyathelo sokuqala sokukhetha

inqubo yokukhiqiza esebenza kahle kakhulu yezingxenye zakho zensimbi.

Ukuze sikusize wenze isinqumo esifanele ngokushesha nangokuzethemba, sikumema ukuthi uhlole

izinsiza ezilandelayo:

Ngifuna okwezifisoizingxenye zensimbi engagqwali ezinezimbobo ezisikiwenjengezihlungi, ama-diffuser,

noma izingxenye ezinembile?

Ithimba lethu lobunjiniyela lingakusiza ukhethe izinto ezifanele, usayizi wembobo, kanye nokukhiqiza

inqubo yephrojekthi yakho.
