Ndikoyenera kudziwa kuti pali zambiri zambiri komanso masinthidwe a zosefera zolowera. Kuphatikiza pa kukwaniritsa zofunikira za kuthamanga kwa kuthamanga (kuthamanga kwapope), ubwino ndi kukana kutentha kuyeneranso kuganiziridwa. Zida zosefera wamba zimaphatikizapo pepala ndi poliyesitala. Mwachiwonekere, iwo sali oyenera kumadera otentha kwambiri. Ndipo kukongola kwawo ndikwambiri, kusefa 5, 3, 1 komanso ngakhale 0,6 microns ufa. Zidzapangitsa kuti digiri ya vacuum isakwaniritsidwe. Zinthu zosefera zitsulo zosapanga dzimbiri sizimalimbana ndi kutentha kwambiri komanso dzimbiri, komanso zimakhala ndi zabwino zochepa. Zimagwirizana kwambiri ndi zofunikira za vacuum sintering process. Chifukwa chake, zinthu zosefera zitsulo zosapanga dzimbiri nthawi zambiri zimasankhidwa kuti zichitike mu vacuum sintering.
Vacuum Sintering ndi njira yopangira thupi la porcelain pansi pa vacuum. Thupi la porcelain lili ndi pores. Mpweya, haidrojeni ndi okosijeni zimatha kutuluka m'mabowo otsekedwa ndi kusungunuka ndi kufalikira; carbon dioxide ndi nayitrogeni si zophweka kuthawa pores chatsekedwa chifukwa cha kusungunuka kwawo otsika, chifukwa pores mu mankhwala ndi kuchepetsa kachulukidwe. Ngati thupi la porcelain litalowetsedwa pansi pa vacuum mikhalidwe, mpweya wonse umatuluka mu pores usanamalize. Kuti mankhwalawa asakhale ndi pores, potero amawongolera kachulukidwe kazinthuzo.
Anthu ambiri amakonzekeretsazoseferakoma popanda zosefera zolowera m'ng'anjo yovumbula. Kwenikweni, panthawi ya vacuum sintering, tinthu tating'onoting'ono titha kupangidwa chifukwa cha kusinthika kwa zinthu, zopangira ufa, kusintha kwamankhwala, ndi zina zambiri.fyuluta yolowerapa pampu ya vacuum.
Pomaliza, zinthu zosefera zitsulo zosapanga dzimbiri zilinso ndi ubwino wosiyana, ndipo ubwino wake umawonetsedwa mu manambala a mesh. Mwachitsanzo, mauna 100 a ma microns 150, mauna 300 a ma microns 50. Koma tinthu ting'onoting'ono tomwe idasefa ndi zazikulu, sichoncho?Lumikizanani nafengati muli ndi zosowa, tikupangirani kapena kupanga yankho!
