Impuphu ye-silica yenziwe nge-quartz yemvelo (i-SiO2) noma i-quartz ehlanganisiwe (i-SiO2 engenasimo ngemva kokuba i-quartz yemvelo incibilikisiwe futhi ipholiswe ekushiseni okuphezulu) ngokuchoboza, ukugaya, ukuntanta, ukuhlanzwa kokuwasha nge-asidi, ukwelashwa kwamanzi okuhlanzekile kakhulu kanye nezinye izinqubo. Ngakho-ke iyini inqubo yokusebenza kanye nokukhiqiza yempuphu ye-silicon? Okulandelayo kuchaza ukusebenza kwempuphu ye-silicon kanye nenqubo yokukhiqiza yei-siliconumshini wokugaya impuphu.

Ngaphezu kwe-coefficient yokwanda kokushisa okuphansi, impahla enhle kakhulu ye-dielectric, ukuqhuba okuphezulu kokushisa, ukusebenza kahle kokumiswa kanye nezinye izakhiwo ezinhle kakhulu, izakhiwo ze-silica powder nazo zifaka okulandelayo:

(1) Ukuvikela okuhle: ngenxa yobumsulwa obukhulu bempuphu ye-silicon, okuqukethwe okuphansi kokungcola, ukusebenza okuzinzile kanye nokuvikela okuhle kakhulu kukagesi, umkhiqizo osuqediwe unokuvikela okuhle kanye nokumelana ne-arc.

(2) Kunganciphisa izinga lokushisa eliphakeme kakhulu le-exothermic le-epoxy resin curing reaction, kunciphise i-linear expansion coefficient kanye ne-shrinkage rate yomkhiqizo osuqediwe, ngaleyo ndlela kuqedwe ukucindezeleka kwangaphakathi komkhiqizo osuqediwe futhi kuvinjelwe ukuqhekeka.

(3) Ukumelana nokugqwala: i-silica powder akulula ukusabela nezinye izinto, futhi ayinayo impendulo yamakhemikhali enama-asidi amaningi nama-alkali. Izinhlayiya zayo zimbozwe ngokulinganayo ebusweni bento, zinokumelana okunamandla nokugqwala.

(4) Ukuhlelwa kwezinhlayiya kunengqondo, okunganciphisa futhi kuqede ukuthungwa kanye nokubekwa kwezingqimba uma kusetshenziswa; Kungathuthukisa amandla okubamba nokucindezela komkhiqizo osuqediwe, kuthuthukise ukumelana nokuguguleka, kwandise ukuhanjiswa kokushisa komkhiqizo osuqediwe, futhi kwandise ukubambezeleka komlilo.

(5) Impuphu ye-silica ephathwe yi-ejenti yokuhlanganisa i-silane iyakwazi ukumanzisa kahle ama-resin ahlukahlukene, ukusebenza kahle kokumuncwa, ukuxuba okulula futhi akukho ukuhlangana.

(6) Ukufakwa kwempuphu ye-silica njengesigcwalisi ku-resin ephilayo akugcini nje ngokuthuthukisa izakhiwo zomkhiqizo osulungisiwe, kodwa futhi kunciphisa nezindleko zomkhiqizo.

Inqubo yokukhiqizwa kwempuphu ye-silica ihlanganisa ukugaya okomile kanye nokugaya okumanzi.

Inqubo yokukhiqiza i-silicon powder yokugaya eyomile: faka izinto zokusetshenziswa ze-silicon powder ku-i-siliconinsimbiukugayaumshini wokugayaumshiniukugaya. Inqubo yokugaya ingaqhubeka nokudla nokukhipha, noma ifake izinto zokusetshenziswa eziningana ngesikhathi esisodwa, bese ikhipha ngemva kokugaya okuqhubekayo izikhathi eziningana; Lapho ikhipha, usayizi wezinhlayiya kufanele ulawulwe yi-fine powder classifier. Imikhiqizo eqinile kufanele ibuyiselwe esigayweni ukuze igaywe kabusha noma njengemikhiqizo, kanti imikhiqizo emihle kufanele ibe yimikhiqizo. Uma igaywa eyomile, lawula ngokuqinile okuqukethwe komswakama kwezinto zokugaya, futhi umkhiqizo ngeke wome.

Inqubo yokukhiqiza i-silica powder yokugaya ngokumanzi: faka inani lezinto zokusetshenziswa ze-silica powder ezinesisindo esilinganisweni sebhola ngesikhathi esisodwa, engeza inani elifanele lamanzi, futhi ukuhlushwa kokusebenza kungu-65% ~ 80%; Ngemva kokugaya okuqhubekayo isikhathi esingaphezu kwamahora ayishumi, thela i-slurry, sebenzisa indlela yokuhlunga ingcindezi noma uyibeke emgqonyeni wezinto ukuze isheshe futhi ikhiphe amanzi ngokwemvelo, bese uthola ikhekhe lezinto ezithwala amanzi; Ngemva kokuphuka nokuhlakazwa yi-crusher, ifakwa ngokulinganayo nangokuqhubekayo ku-dryer engenalutho yomgodi, bese umkhiqizo utholakala ngemva kokomiswa.

Enqubweni yokukhiqiza i-dry silicon powder, i-silicon powder grinder yobungcweti ingakhethwa.I-HLMXimpuphu ye-silicon okuqondile kakhuluukugayaumshini wokugayaekhiqizwe yi-HCMilling (Guilin Hongcheng) ingadlala indima enkulu enqubweni yokukhiqiza i-dry silicon powder. Ngenxa yokusebenza kwayo kahle kokukhiqiza, ukunemba okuphezulu kokuhlukaniswa kanye nekhwalithi ephezulu yemikhiqizo yokugaya, ithole udumo kumakhasimende, futhi ifaneleka kakhulu njenge-ukukhiqizwa kwempuphu ye-siliconumugqaimishini.

Njengomkhiqizi onolwazi lwemishini yezimayini nemishini, i-HCMilling (Guilin Hongcheng) igxile ekukhiqizeni izinhlobo ezahlukene zemishini yezimayini.ukugaya i-silicon powderumshini wokugayaimishini. Uma ufuna ukwazi okwengeziwe ngenqubo yokukhiqiza i-silicon powder, sicela uthintane ne-HCM ukuthola ulwazi olwengeziwe.
