Mikanda yagalasi imapangidwa ndi kuwombera mchenga wagalasi. Malinga ndi kukula kwake, mikanda yagalasi imatha kugawidwa m'mikanda yagalasi (mikanda yagalasi ndi mtundu wa mikanda yagalasi ndipo imatanthawuza magawo olimba okhala ndi tinthu tating'ono osakwana 1 mm) ndi mikanda yagalasi. Malinga ndi ntchito, imatha kugawidwa m'mikanda yagalasi yowunikira, mikanda yagalasi ya sandblasting, mikanda yagalasi yopera, ndi mikanda yagalasi yodzaza. Pakati pawo, mikanda yowunikira imatha kugawidwa kukhala mikanda yagalasi yoteteza chitetezo ndi mikanda yagalasi yowonekera; Malinga ndi index refractive, akhoza kugawidwa mu general refractive index ndi mkulu refractive index mikanda galasi.
Zomatira zamtundu wosasunthika zimakhala ndi ntchito yabwino yolimbana ndi dzimbiri ndipo zimatha kupirira kutentha kwa asidi, alkali, mchere ndi utsi wamagalimoto kwa nthawi yayitali, kotero zimatha kuteteza msewu kuti zisawonongeke ndikupeza mphamvu zokwanira. Tikudziwa kuti mtengo womanga misewu ndi wokwera kwambiri.
Kuwonekera kwamitundu kosasunthika kumatha kupangitsa chilengedwe kukhala chokongola, komanso kumalimbikitsa chitetezo chamsewu, chomwe chimagwiritsidwa ntchito mochulukirachulukira.kumanga m'magawo ena amsewu onyowa, njira yapitayi siyingagwiritsidwe ntchito pomanga, komanso kukhudzidwa kwa kutentha kwa madzi. ziyenera kuganiziridwa panthawiyi.
Yang'anani zodetsedwa: Monga mikanda yagalasi yamitundu ndi njira yopangira yachiwiri, mafakitale ambiri amagalasi amagwiritsa ntchito kuyandama kwa malawi kuti apange mikanda yagalasi. The zopangira ndi zobwezerezedwanso galasi. Zonyansa zidzakhudzidwa ndi kupanga komanso muzopangira. Chodetsedwa ichi chikuwonekera mu mawanga akuda mu mankhwala, omwe sangathe kupeŵa.
1. Zomwe zimapangidwira ndi silika wa inert, ndipo palibe nkhawa zokhudzana ndi kusokoneza kwa mankhwala;
2. Zozungulira zotanuka particles. Impact resistant, itha kugwiritsidwa ntchito mobwerezabwereza
3 Pamwamba pa mpirawo sichidzawononga malo opangidwa ndi makina ndi miyeso yolondola;
Ø Calcium yokolola ndi yochuluka, yowonjezereka ndi 50% poyerekeza ndi waya wachitsulo wa calcium;
Ø Calcium kuchira ndikokhazikika, kusinthasintha kochepa pakati pa nthawi ya ng'anjo;
Ø Kutentha pang'ono, chitetezo chabwino cha chilengedwe;
