(1) Zinthu zogwirira ntchito zoteteza kutentha
Njira zazikulu zachikhalidwe zogwirira ntchito zapamlengalenga zomwe zimagwira ntchito bwino kwambirizipangizo zotetezera kutenthandi RTM (Resin Transfer Molding), kupanga, ndi kuyika, ndi zina zotero. Pulojekitiyi ikugwiritsa ntchito njira yatsopano yopangira zinthu zambiri.
Kukonza RTM:
① Kuyika nsalu ya ulusi: nsalu ya ulusi wa quartz yokonzedwa imayikidwa mu dzenje la nkhungu nthawi imodzi;
② Kulowetsa utomoni: utomoni ndi chothandizira zimasakanizidwa mu chosakanizira chosasunthika kutsogolo kwa mfuti yolowetsamo ndipo zimalowetsedwa mu dzenje la nkhungu lophimbidwa ndi nsalu ya ulusi.
③ Kuyeretsa utomoni: malo obisika a nkhungu amatenthedwa kuti utomoniwo upitirire kukonzedwa;
(iv) Kuchotsa zinthu: Utomoni ukatha kukonzedwa ndi kupangidwa, nkhungu imatsegulidwa kuti papezeke chinthu chomaliza chopangidwa.
Pambuyo pa njira ya RTM (Resin Transfer Molding), nsalu ya quartz fiber imakonzedwa ndikuyikidwa ndi chipolopolo chachitsulo, ndipo chinthucho pambuyo pa seti chimayesedwa bwino pambuyo pa mayeso a magwiridwe antchito, omwe ndi chinthu chomalizidwa.

(2) Zipangizo zophatikizika zowonekera bwino za mafunde
Ulusi wa quartz wolimbikitsidwaZosakaniza zowonekera bwino za mafunde a ceramic zomwe zakonzedwa ndi njira yopangira organic precursor impregnation cracking (PIP). Njira ya PIP ndikugwiritsa ntchito organic precursor impregnated fiber preforms, kenako pyrolysis, kupanga quartz fiber matrix yomwe imayikidwa m'malo obisika a preform pa billet, mu billet pambuyo pa utoto wopopera kuti iwunikire, kuyang'aniridwa ndi kuyenerera komwe ndi chinthu chomalizidwa. Pofuna kuonetsetsa kuti pamwamba pa zinthu zomwe zimafunika kutentha kwa density ndi kotsika kwambiri kuposa njira yachikhalidwe yopopera kutentha, zimatha kuchepetsa kuwonongeka kwa ulusi wa quartz, ndipo zimakhala ndi mawonekedwe ofanana ndi net, makamaka oyenera kukonzekera zigawo zazikulu za mafunde-transparent.

(3) Zipangizo zapadera zotetezera kutentha
Thensalu ya ulusi wa quartzMukakonzekera kulowa m'bowo la nkhungu, utomoni udzalowetsedwa m'bowo la nkhungu kuti likhale lodzaza ndi nsalu ya ulusi, kutentha bowo la nkhungu kuti lifulumizitse kuchiritsa utomoni, kuumba utomoni, kutsegula bowolo ndikupeza zipangizo zapadera zotetezera kutentha.
