Ama-microsphere engilazi angenalutho Zinezindlela eziningi zokusebenzisa, kodwa enye evelele kakhulu embonini yerabha ukwenza imikhiqizo efana ne-silicone rubber sealants. Inzuzo enkulu enikezwa yi-hollow glass microspheres imayelana nokunciphisa isisindo okuvumela ukusetshenziswa okulula kokuthutha okubushelelezi. I-glass microsphere yethu inikeza ukuvikela okwanele, ukuqina, kanye nokuqina okusiza hhayi nje kuphela ukuthutha kodwa nezinye izinhlelo zokusebenza.
Isetshenziswa kanjani ngeRubber?
Ngokuphathelene nocwaningo, kufanele kuqondwe ukuthi ubukhulu benhlayiya, ikhono layo maqondana nokubopha, kanye nomthwalo enawo ekunqumeni amandla, ukumelana, kanye nokuqina kwezinye izinto ezihlanganisiwe. Ucwaningo oluningana lufinyelele esiphethweni sokuthi izakhiwo zerabha zathuthukiswa kakhulu lapho kufakwa i-microsphere yengilazi engenalutho kuzo. Izifundo ziphakamisa nokuthi uma into ine-viscosity encibilika kancane ngokwemvelo lokho kungenziwa ngokusebenzisa ama-microsphere engilazi engenalutho ku-polyester kanye nama-epoxy resins.
Kolunye ucwaningo, ukuziphatha kwe- ama-microsphere engilazi angenalutho kwafundwa ngokwehlukana kanye namandla lapho kufakwa ezintweni ezihlanganisiwe njengerabha. Ama-microsphere engilazi angenalutho anamandla amaningi uma kuqhathaniswa nokukhiqizwa kwenhlanganisela ngokuzimela. Ngaphezu kwalokho, lapho kulungiswa izinto ezihlukahlukene ezivela kuma-microsphere engilazi angenalutho, kwaphawulwa ukuthi ukuqina kwezinto kuba phezulu lapho i-microsphere yengilazi engenalutho iphezulu ngobuningi ezintweni ngesikhathi sokufakwa. Ngaphezu kwalokho, amandla okumunca amandla ezinto akhuphuke afinyelela cishe ku-40% ngokusebenzisa i-microsphere yengilazi engenalutho. Esinye sezifundo ezibaluleke kakhulu kwakumayelana nohlobo lwe-dielectric lwama-microsphere engilazi angenalutho ayegcwele izinto ezihlanganisiwe ezifaka esikhundleni salokhu futhi kulokhu, kwaphawulwa ukuthi ukuvumelana kwanda kanye nokulahlekelwa kwehla ngokwe-dielectric lapho ama-microsphere engilazi angenalutho engezwa ngobuningi obandisiwe. Ngaphezu kwalokho, ngokwesimo sokuqhekeka ngokwe-microsphere yengilazi engenalutho, kwaphawulwa ukuthi ukufakwa kwama-microsphere empeleni kwathuthukisa i-flexural modulus futhi kwanciphisa ukuqina namandla ngokwe-fracture.
I-hollow microsphere iyinto ekhethekile kakhulu futhi engeyona into ephilayo futhi inokusetshenziswa okuhlukahlukene kakhulu. Inzuzo ecacile kakhulu ye-hollow cavity yayo ukuthi ihlinzeka ngokuhlukaniswa okukhulu maqondana nokushisa futhi inomoya omningi kakhulu. Ngakho-ke, maqondana nokusetshenziswa okusebenzayo embonini yerabha, isici esibaluleke kakhulu ukufakwa kwayo erabha ye-silicone ehlanganisa hhayi nje kuphela ama-sphere aphelele, kodwa futhi nalawo aqhekekile ngezilinganiso ezihlukene. Ukusetshenziswa embonini yerabha kusikisela nokuthi ngisho nalapho ama-sphere engilazi angenalutho ephukile, kwandisa lezi zakhiwo okuxoxwe ngazo ngenhla.
