Q7: Ndi njira iti yomwe imapereka kulondola kwabwinoko kwa miyeso?

Ndi njira iti yomwe imapereka kulondola kwabwinoko kwa miyeso: kusungunula kapena kusungunula?

Kupopera nthawi zambiri kumapereka ulamuliro wabwino kwambiri pazinthu zazing'ono komanso zovuta chifukwa cha:

*Zinthu zodziwika bwino

*Kusintha kochepa panthawi yotenthetsera

* Kupanga zinthu zooneka ngati ukonde

Kusungunula ndi kuponyera kumatha kufooka ndi kusokonekera panthawi yolimba,

nthawi zambiri zimafuna makina owonjezera kuti akwaniritse kulekerera kolimba.

Izi zimapangitsa kuti sintering ikhale yoyenera kwambiri pa masensa, zida zamankhwala, ndi zida zazing'ono zamakaniko.

Q8: Kodi ma microstructures amasiyana bwanji pakati pa zitsulo zosungunuka ndi zosungunuka?

Kodi ma microstructures amasiyana bwanji pakati pa zitsulo zosungunuka ndi zosungunuka?

Zitsulo zosungunuka zimakhala ndi tinthu ta ufa tolumikizidwa tokhala ndi malire olamulidwa pakati pa tinthu tating'onoting'ono

ndi ma porosity osankha. Kapangidwe kake kakang'ono kakhoza kupangidwa kuti kakwaniritse kayendedwe kake,

kusefa, kapena makhalidwe a makina.

Zitsulo zosungunuka zimauma kuchokera ku mkhalidwe wamadzimadzi ndipo nthawi zambiri zimapanga tinthu tating'onoting'ono tomwe timakhala ndi mapangidwe opitilira.

Ngakhale izi zingapereke mphamvu yabwino kwambiri, sizimasinthasintha ngati ufa.

Kusiyana kwakukulu kumeneku kukufotokoza chifukwa chakezitsulo za ufa poyerekeza ndi kusungunuka kwachikhalidwezimatsogolera ku

magwiridwe antchito osiyanasiyana ndi mwayi wogwiritsa ntchito.

Mapeto

Kumvetsetsa kusiyana pakati pakusungunula motsutsana ndi kusungunukandi sitepe yoyamba yosankha

njira yothandiza kwambiri yopangira zitsulo zanu.

Kuti tikuthandizeni kupanga chisankho choyenera mwachangu komanso molimba mtima, tikukupemphani kuti mufufuze

zinthu zotsatirazi:

Ndikufuna zinthu zapaderazigawo zachitsulo chosapanga dzimbiri zopindikamonga zosefera, zotulutsira mpweya,

kapena zigawo zolondola?

Gulu lathu la uinjiniya lingakuthandizeni kusankha zinthu zoyenera, kukula kwa ma pore, ndi kupanga

njira yogwirira ntchito yanu.
