I-Silicon micro powder iyinto engeyona eyensimbi engenabo ubuthi, engenambitheki futhi engenakungcola, eyenziwe nge-quartz yemvelo (i-SiO2) noma i-quartz ehlanganisiwe (i-SiO2 engabonakali ye-quartz yemvelo ngemva kokuncibilika nokupholisa okushisa okuphezulu) ngokuchoboza, ukugaya, ukuntanta, ukuhlanzwa kwe-pickling, ukwelashwa kwamanzi okuhlanzekile kakhulu kanye nezinye izinqubo. Yiziphi izindlela zokusebenzisa i-silica powder? I-HCMilling (i-Guilin Hongcheng) ingumkhiqizi we-i-silicon microumshini wokugaya impuphuOkulandelayo kuchaza ukusetshenziswa kwe-silicon micro powder:

Izici ze-silicon micro powder yilezi: inkomba yokubuyisa engu-1.54-1.55, ubulukhuni be-Mohs obungu-7, ubuningi obungu-2.65g/cm3, iphuzu lokuncibilika elingu-1750 ℃, i-dielectric constant engaba ngu-4.6 (1MHz). Ukusebenza kwayo okuyinhloko kufaka phakathi:

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

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

(3) Ukumelana nokugqwala: i-silicon micro powder akulula ukusabela nezinye izinto, futhi ayisabelani ngamakhemikhali nama-acid amaningi nama-alkali. Izinhlayiya zayo zimbozwe ngokulinganayo ebusweni bento, ngokumelana okunamandla nokugqwala.

(4) Ukuhlelwa kosayizi wezinhlayiya kunengqondo, okunganciphisa futhi kuqede ukubola kanye nokuhlukaniswa ngesikhathi sokusetshenziswa; Kungathuthukisa amandla okubamba nokucindezela komkhiqizo osuqediwe, kuthuthukise ukumelana nokuguguleka, kwandise ukuhanjiswa kokushisa komkhiqizo osuqediwe, futhi kwandise ukubambezeleka komlilo.

(5) Impuphu ye-silicon ephathwe nge-silane coupling agent 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.

Ukusetshenziswa okuyinhloko kwe-silicon powder:

(1) Ukusetshenziswa ku-CCL: I-Silicon micro powder uhlobo lokugcwalisa olusebenzayo. Ingathuthukisa ukufudumala, ukuqhuba ukushisa, ukuzinza kokushisa, ukumelana ne-asidi ne-alkali (ngaphandle kwe-HF), ukumelana nokuklwebheka kanye nokuncipha komlilo kwe-CCL, ithuthukise amandla okugoba kanye nokuzinza kobukhulu bebhodi, inciphise izinga lokunwebeka kokushisa kwebhodi, futhi ithuthukise ukungaguquguquki kwe-dielectric kwe-CCL. Ngesikhathi esifanayo, i-silicon micro powder isetshenziswa kabanzi embonini ye-laminate embozwe ngethusi ngenxa yezinto zayo zokusetshenziswa ezicebile kanye nentengo ephansi, okunganciphisa izindleko ze-laminate embozwe ngethusi.

(2) Ukusetshenziswa ezintweni zokubhaka ze-epoxy resin: Njengenye yezinto ezivamile zokugcwalisa izinto zokubhaka ze-epoxy resin, i-silicon micro powder inendima esobala ekuthuthukiseni ezinye izakhiwo zomzimba ze-epoxy resin. Isibonelo, ukwengeza i-silicon micro powder esebenzayo ezintweni zokubhaka ze-epoxy resin kungathuthukisa kakhulu ukumelana nomthelela wezinto zokubhaka ze-epoxy resin futhi kunciphise i-viscosity yezinto zokubhaka ze-epoxy resin.

(3) Ukusetshenziswa kwe-epoxy plastic sealant: i-epoxy molding compound (EMC), eyaziwa nangokuthi i-epoxy resin molding compound kanye ne-epoxy plastic sealant, iwuhlobo lwe-powder molding compound exutshwe ne-epoxy resin njenge-matrix resin, i-phenolic resin esebenza kahle njenge-ejenti yokwelapha, i-filler efana ne-silicon micro powder, kanye nezinye izithasiselo ezahlukahlukene. Ekwakhekeni kwe-EMC, i-silicon powder iyona esetshenziswa kakhulu, futhi isilinganiso sesisindo se-silicon powder kuya ku-epoxy molding compound singu-70% ~ 90%.

Inqubo yokukhiqiza i-silicon micro powder ngokuvamile iyafana ngokwezakhiwo ze-ore eluhlaza, i-mineralology yenqubo ye-ore nezinye izici kanye nezidingo zabasebenzisi zekhwalithi yomkhiqizo. Ukukhiqizwa kwe-high-purity superfine silicon powder kutholakala ngokuhlela okwengeziwe kwe-superfine noma ukugaya ngokusekelwe ekulungiseleleni isihlabathi esihlanzekile kakhulu. Ukukhethwa kwemishini yokucubungula kubaluleke kakhulu, ikakhulukazi ukukhethwa kwemishini yokugaya neyokuhlukanisa i-superfine. Ukukhethwa kwemishini yokugaya neyokuhlukanisa i-superfine kuzothinta ngqo umkhiqizo kanye nekhwalithi yemikhiqizo yokugcina kanye nokuma kwezinhlayiya ze-powder. I-HCMilling (Guilin Hongcheng), njengomkhiqizi we-silicon micro powder grinding mill, i-HLMX silicon micro powder vertical mill yethu iyimishini efanelekile yokukhiqiza i-ultra-fine silicon micro powder, enezinzuzo eziningi ezifana nomthamo omkhulu, indawo ephezulu ethile, okuqukethwe okuphansi kokungcola, njll. Uhlelo lokuhlukanisa umoya lwesibili luhlelwe, futhi i-classifier kanye ne-fan kulawulwa ukulawulwa kwesivinini sokuguqulwa kwemvamisa, ngakho-ke ukusebenza kahle kokuhlukanisa i-powder kuphezulu; Ama-concentrator e-single head kanye ne-multi head powder asetshenziswa ukulawula ngempumelelo ubuncane bemikhiqizo eqediwe; Ubuncane bomkhiqizo oqediwe busukela ku-3 μ M kuya ku-22 μ m. Kungatholakala izinhlobo ezahlukene zemikhiqizo efanelekile.

Ama-HCMi-silicon microumshini wokugaya impuphuidlule enkingeni yomthamo wezinye izigayo ezisebenza kahle kakhulu njengegayo lokugeleza komoya lendabuko kanye negayo lokudlidliza, elinomphumela wehora ongu-4-40t/h, kanye nokusetshenziswa kwamandla okuphansi kakhulu kunokusetshenziswa kwemishini yokugaya efanayo esebenza kahle kakhulu. Kuyindlela enobungani nemvelo futhi esindisa amandla.si-silicon microumshini wokugaya impuphuUma unezidingo ezifanele, sicela usithinte ukuze uthole imininingwane bese usinikeze ulwazi olulandelayo:
