3- uxinano lokukhanya
Uxinano lwee-microspheres zeglasi ezingenanto lumalunga neshumi lee-density zee-filler particles zemveli. Emva kokuzaliswa, ubunzima besiseko semveliso bunokuncipha kakhulu, ii-resin ezininzi zemveliso zinokutshintshwa kwaye zigcinwe, kwaye iindleko zemveliso zinokuncitshiswa.
4-Ukuthanda ukucola kakhulu
Iiglasi ezincinci ezingenanto kulula ukuzimanzisa nokuzisasaza, kwaye zinokuzaliswa kwiiresini ezininzi zethermoplastic ezisebenzisa ithermosetting, ezifana nepolyester, i-epoxy resin, i-polyurethane, njl.njl.
5-Ukungabi namali kakuhle
Ekubeni ii-microspheres zeglasi ezingenanto ziyi-spheres ezincinci, zinokuguquguquka okungcono kwii-resin ezingamanzi kunee-flake, i-needle okanye i-irregular fillers, ngoko ke zisebenza kakuhle ekuzaliseni i-mold. Okubaluleke ngakumbi, ii-microbeads ezincinci ziyi-isotropic, ngoko akukho ngxaki yamazinga okuncipha angaguqukiyo kwiindawo ezahlukeneyo ngenxa yokujongwa, okuqinisekisa uzinzo lobukhulu bemveliso kwaye ayizukugoba.
6- Ubushushu kunye nobushushu besandi
Ingaphakathi lee-microspheres zeglasi ezingenanto liyigesi encinci, ngoko ke lineempawu zokuthintela isandi kunye nokuthintela ubushushu, kwaye lizalisi elihle kakhulu kwiimveliso ezahlukeneyo zokuthintela ubushushu kunye nokuthintela isandi. Iimpawu zokuthintela ubushushu zee-microspheres zeglasi ezingenanto zingasetyenziselwa ukukhusela iimveliso kwi-thermal shock ebangelwa kukutshintshana phakathi kokufudumala okukhawulezayo kunye neemeko zokupholisa ngokukhawuleza. Ukumelana okuphezulu kunye nokufunxwa kwamanzi okuncinci kakhulu kwenza ukuba isetyenziswe kakhulu kwimveliso yezinto zokuthintela ikhebula.
7- Ukufunxwa kweoyile okuphantsi
Amasuntswana esphere agqiba ukuba inendawo encinci yomphezulu ethile kunye nesantya esiphantsi sokufunxwa kweoyile. Ngexesha lenkqubo yokusetyenziswa, ubungakanani be-resin bunokuncipha kakhulu, kwaye i-viscosity ayizukwanda kakhulu nangona kucingelwa ukuba kukho inani eliphezulu lokongeza, nto leyo ephucula kakhulu imveliso kunye neemeko zokusebenza. Yonyusa ukusebenza kakuhle kwemveliso nge-10% ukuya kwi-20%.
