Iimicrosphere zeglasi ezingenanto ziimicrospheres zeglasi ezicutshungulwayo ngokukodwa, ezibonakaliswa ikakhulu kukuxinaniswa okusezantsi kunye nokuhanjiswa kobushushu obuphantsi kuneemicrospheres zeglasi. Luhlobo olutsha lwemathiriyeli ye-micron-scale lightweight eyaphuhliswa ngoo-1950 kunye noo-1960. Icandelo layo eliphambili li-borosilicate, kunye nobukhulu be-particle jikelele ye-10 ~ 250μm kunye nobukhulu bodonga lwe-1 ~ 2μm; Amaso eglasi angenamngxuma aneempawu zamandla acinezelayo aphezulu, indawo yokunyibilika ephezulu, ukumelana noxinzelelo oluphezulu, kunye ne-thermal conductivity encinci kunye ne-thermal shrinkage coefficient. Yaziwa ngokuba "yinto yeminyaka yobudala" kwinkulungwane yama-21.Iimicrosphere zeglasi ezingenanto zinokuncipha okucacileyo kobunzima kunye nokugqunyelelwa kwesandi kunye neziphumo zokugquma kwe-thermal, ukuze iimveliso zibe nokusebenza kakuhle kokuchasana nokuqhekeka kunye nokusebenza kwakhona, kwaye zisetyenziswa ngokubanzi kwizinto ezidityanisiweyo ezifana neglasi yefiber eqinisiweyo yeplastiki, ibhastile eyenziweyo, i-agate eyenziweyo, kunye nakwi-agate yokwenziwa. ishishini lepetroleum, i-aerospace kunye nemizi-mveliso ye-aerospace. , oololiwe abatsha abanesantya esiphezulu, iimoto kunye neenqanawa, ii-thermal insulation coatings kunye nezinye iinkalo ziye zakhuthaza ngokufanelekileyo uphuhliso lwelizwe lam lwezenzululwazi kunye nezobuchwepheshe. Ukuze kuhlangatyezwane neemfuno ze-dielectric ephantsi, ilahleko ephantsi kunye nobunzima obulula bezinto zonxibelelwano ze-5G, ii-microspheres zeglasi ezingenanto nazo zidlala indima ebalulekileyo ngenxa yeendleko zabo eziphantsi kunye nokusebenza kakuhle.
1 – Isithako
Ukwakhiwa kweekhemikhali zemicrospheres yeglasi engenanto (umlinganiselo wobunzima)
SiO2: 50% -90%, Al2O3: 10% -50%, K2O: 5% -10%, CaO: 1% -10%, B2O3: 0-12%

3- ukuxinana kokukhanya
Ubuninzi beemicrospheres zeglasi ezingenanto malunga nesinye eshumini soxinaniso lwamasuntswana aqhelekileyo okuzalisa. Emva kokuzaliswa, ubunzima besiseko bemveliso bunokuncitshiswa kakhulu, ii-resin ezininzi zokuvelisa zingatshintshwa kwaye zigcinwe, kwaye iindleko zemveliso zingancitshiswa.
4-Lipophilicity
I-Microspheres yeglasi engenanto kulula ukumanzisa kwaye isasazeke, kwaye inokuzaliswa kwiindawo ezininzi ze-thermosetting thermoplastic resins, ezifana ne-polyester, i-epoxy resin, i-polyurethane, njl.
5-Imali entle yokuhlawula amatyala
Kuba ii-microspheres zeglasi ezingenanto zizingqukuva ezincinci, zine-fluidity engcono kwi-resin elulwelo kuneflake, inaliti okanye izihluzi ezingaqhelekanga, ngenxa yoko banomsebenzi ogqwesileyo wokuzalisa umngundo. Okubaluleke ngakumbi, i-microbeads ezincinci ziyi-isotropic, ngoko ke akukho nto iphosakeleyo yamazinga e-shrinkage angahambelaniyo kwiindawo ezahlukeneyo ngenxa yokuqhelaniswa, okuqinisekisa ukuzinza kwe-dimensional yemveliso kwaye ayiyi kulwa.
I-6- I-Thermal kunye ne-sound insulation insulation
Ingaphakathi leglasi ye-microspheres engenanto yigesi encinci, ngoko ineempawu zokugquma isandi kunye nokugquma ubushushu, kwaye sisigcwalisi esigqwesileyo sokufakwa kwe-thermal eyahlukeneyo kunye neemveliso zokugquma isandi. Iipropathi zokugquma ii-microspheres zeglasi ezingenanto zingasetyenziselwa ukukhusela iimveliso kwi-thermal shock ebangelwa kukutshintshana phakathi kokufudumeza ngokukhawuleza kunye neemeko zokupholisa ngokukhawuleza. Ukuchasana okuphezulu okuthe ngqo kunye nokufunxwa kwamanzi aphantsi kakhulu kwenza ukuba kusetyenziswe ngokubanzi kwimveliso yezinto zokugquma intambo.
7- Ukufunxa ioli ephantsi
Amasuntswana esphere amisela ukuba inowona mmandla uncinci we-oyile kunye nesantya esisezantsi sokufunxa i-oyile. Ngexesha lenkqubo yokusetyenziswa, inani le-resin lingancitshiswa kakhulu, kwaye i-viscosity ayiyi kunyuka kakhulu nangaphantsi kwexabiso eliphezulu lokongeza, eliphucula kakhulu imveliso kunye neemeko zokusebenza. Ukwandisa impumelelo yemveliso nge-10% ukuya kwi-20%.
8- I-dielectric ephantsi rhoqo
Ixabiso lika Dk le-microspheres yeglasi engenanto yi-1.2 ~ 2.2 (100MHz), enokuphucula ngokufanelekileyo iipropati ze-dielectric zezinto.
