Ama-microsphere engilazi angenalutho yizinhlayiya zeglasi ezicutshungulwe ngokukhethekile, ezibonakala kakhulu ngobuningi obuphansi kanye nokushisa okuphansi kunezinhlayiya zeglasi. Luhlobo olusha lwezinto ezilula ze-micron-scale ezathuthukiswa ngawo-1950 nawo-1960. Ingxenye yalo eyinhloko yi-borosilicate, enosayizi wezinhlayiya ojwayelekile ongu-10 ~ 250μm kanye nobukhulu bodonga obungu-1 ~ 2μm; ubuhlalu beglasi obungenalutho bunezimpawu zamandla aphezulu okucindezela, iphuzu lokuncibilika eliphezulu, ukumelana okuphezulu, kanye nokushisa okuncane kanye nokushisa okuncishisiwe. Kwaziwa ngokuthi "izinto zesikhathi sesikhala" ekhulwini lama-21. Ama-microsphere engilazi angenalutho zinemiphumela ecacile yokunciphisa isisindo kanye nokufakwa komsindo kanye nokufakwa kokushisa, ukuze imikhiqizo ibe nokusebenza okuhle kokulwa nokuqhekeka kanye nokusebenza kabusha, futhi isetshenziswa kabanzi ezintweni ezihlanganisiwe njengepulasitiki eqiniswe ngefayibha yengilazi, imabula yokwenziwa, i-agate yokwenziwa, kanye nasembonini kaphethiloli, izimboni zezindiza kanye nezindiza. , izitimela ezintsha ezinesivinini esikhulu, izimoto nemikhumbi, izembozo zokufakwa kokushisa kanye neminye imikhakha kukhuthaze ngempumelelo intuthuko yemisebenzi yesayensi nezobuchwepheshe yezwe lami. Ukuze kuhlangatshezwane nezidingo zezinto zokuxhumana ze-5G ezisebenzisa ugesi ophansi, ukulahlekelwa okuphansi kanye nesisindo esincane, ama-microsphere engilazi angenalutho nawo adlala indima ebaluleke kakhulu ngenxa yezindleko zawo eziphansi kanye nokusebenza okuhle.
1 – Isithako
Ukwakheka kwamakhemikhali kwama-microspheres engilazi angenalutho (isilinganiso sobuningi)
I-SiO2: 50% -90%, Al2O3: 10%-50%, K2O: 5%-10%, CaO: 1% -10%, B2O3: 0-12%
2- Izici
umbala omhlophe qwa
Ingasetshenziswa kabanzi kunoma yimiphi imikhiqizo enezidingo zokubukeka nombala.
3- ukukhanya okukhulu
Ubuningi be-microspheres zeglasi ezingenalutho cishe buyingxenye yeshumi yobuningi bezinhlayiya zendabuko zokugcwalisa. Ngemva kokugcwalisa, isisindo esiyisisekelo somkhiqizo singancishiswa kakhulu, ama-resin amaningi okukhiqiza angashintshwa futhi alondolozwe, futhi izindleko zomkhiqizo zingancishiswa.
4-Ukungakwazi ukuphefumula kahle
Ama-microsphere engilazi angenalutho kulula ukuwamanzisa nokuwahlakaza, futhi angagcwaliswa kuma-resin amaningi e-thermoplastic e-thermosetting, njenge-polyester, i-epoxy resin, i-polyurethane, njll.
5-Uketshezi oluhle
Njengoba ama-microsphere engilazi angenalutho eyizimbulunga ezincane, anokugeleza okungcono kuma-resin aketshezi kunezinhlayiya ezicwebezelayo, izinaliti noma izigcwalisi ezingajwayelekile, ngakho-ke anokusebenza okuhle kakhulu kokugcwalisa isikhunta. Okubaluleke kakhulu, ama-microbead amancane ayi-isotropic, ngakho-ke akukho nkinga yamazinga okuncipha angaguquki ezingxenyeni ezahlukene ngenxa yokuma, okuqinisekisa ukuzinza komkhiqizo futhi ngeke kugobe.
6- Ukushisa nokushisa komsindo
Ingaphakathi lama-microsphere engilazi engenalutho liyigesi elincane, ngakho-ke linezici zokuvimbela umsindo kanye nokuvimbela ukushisa, futhi liyisithako esihle kakhulu sokugcwalisa imikhiqizo ehlukahlukene yokuvimbela ukushisa kanye nokuvimbela umsindo. Izakhiwo zokuvimbela ukushisa zama-microsphere engilazi engenalutho zingasetshenziswa futhi ukuvikela imikhiqizo ekushaqekeni kokushisa okubangelwa ukushintshana phakathi kokushisa okusheshayo kanye nezimo zokupholisa okusheshayo. Ukumelana okuphezulu okuqondile kanye nokumuncwa kwamanzi okuphansi kakhulu kwenza kusetshenziswe kabanzi ekukhiqizweni kwezinto zokuvimbela ikhebula.
7- Ukumuncwa okuphansi kwamafutha
Izinhlayiya ze-sphere zinquma ukuthi inendawo encane kakhulu yobuso kanye nesilinganiso esiphansi sokumuncwa kwamafutha. Ngesikhathi senqubo yokusebenzisa, inani le-resin lingancishiswa kakhulu, futhi i-viscosity ngeke ikhule kakhulu ngisho nangaphansi kwesisekelo senani eliphezulu lokwengeza, okuthuthukisa kakhulu izimo zokukhiqiza nokusebenza. Khulisa ukusebenza kahle kokukhiqiza ngo-10% kuya ku-20%.
8- I-dielectric constant ephansi
Inani le-Dk lama-microspheres engilazi engenalutho lingu-1.2 ~ 2.2 (100MHz), elingathuthukisa ngempumelelo izakhiwo ze-dielectric zezinto.
Amapulasitiki okuhlobisa ubuhlalu beglasi obungenalutho
(1) Ukuze kuguqulwe amapulasitiki obunjiniyela njenge-nylon, i-PP, i-PBT, i-PC, i-POM, njll., kungathuthukisa ukugeleza kwamanzi, kuqede ukuvezwa kwe-fiber yengilazi, kunqobe ukugoba, kuthuthukise ukusebenza okubamba umlilo, kunciphise ukusetshenziswa kwe-fiber yengilazi, futhi kunciphise izindleko zokukhiqiza.
(2) Ukugcwalisa nge-PVC eqinile, i-PP, i-PE, nokukhiqiza izinto ezifakwe iphrofayili, amapayipi namapuleti kungenza imikhiqizo ibe nokuzinza okuhle kobukhulu, kuthuthukise ukuqina kanye nokushisa okumelana nokushisa, kuthuthukise ukusebenza kwezindleko zemikhiqizo, kuthuthukise ukusebenza kahle kokukhiqiza futhi kunciphise izindleko.
(3) Ukugcwalisa izintambo ze-PVC, i-PE nezinye izinto zokufaka umswakama kungathuthukisa ukumelana nokushisa okuphezulu komkhiqizo, ukuvikela umswakama, ukumelana ne-asidi ne-alkali kanye nezinye izakhiwo kanye nokusebenza kokucubungula umkhiqizo, kwandise umkhiqizo futhi kunciphise izindleko.
(4) Ukugcwalisa ipuleti lethusi le-epoxy resin kunganciphisa ukujiya kwe-resin, kwandise amandla okugoba, kuthuthukise izakhiwo zayo zomzimba nezomshini, kwandise izinga lokushisa lokushintsha kwengilazi, kwandise ukungaguquguquki kwe-dielectric, kwandise ukumuncwa kwamanzi, futhi kwandise izindleko.
(5) Ukugcwalisa nge-polyester engagcwali kunganciphisa izinga lokuncibilika kanye nezinga lamanzi okugeza lomkhiqizo, kuthuthukise ukumelana nokuguguleka kanye nokuqina, futhi kube nezimbobo ezincane ngesikhathi sokulamina nokugqoka. Isetshenziselwa imikhiqizo ye-FRP, amasondo okupholisha, amathuluzi, njll.
(6) Ukugcwalisa nge-silicone resin kungathuthukisa izakhiwo zomzimba nezemishini, futhi inani elikhulu lokugcwalisa linganciphisa kakhulu izindleko, okuyinto efanelekile ekukhiqizeni isikhunta.
