I-silicon micro powder iyi-non-toxic, ayinambitheki futhi ingenawo ukungcola kwe-inorganic non-metallic material, eyenziwe nge-quartz yemvelo (SiO2) noma i-quartz ehlanganisiwe (i-amorphous SiO2 ye-quartz yemvelo ngemva kokuncibilika nokupholisa kwezinga lokushisa eliphezulu) ngokuchotshozwa, ukugaya, ukuntanta, ukuhlanzwa kwe-pickling, ezinye izinqubo zokuhlanzeka kwamanzi amaningi. Yiziphi ukusetshenziswa kwe-silica powder? I-HCMilling(Guilin Hongcheng) ingumkhiqizi wei-silicon microimpushana yokugaya. Okulandelayo kuchaza ukusetshenziswa kwe-silicon micro powder:

Izici ze-silicon micro powder yilezi: inkomba ye-refractive 1.54-1.55, ukuqina kwe-Mohs mayelana ne-7, ukuminyana okungu-2.65g/cm3, indawo encibilikayo 1750 ℃, i-dielectric engaguquki mayelana ne-4.6 (1MHz). Ukusebenza kwayo okuyinhloko kuhlanganisa:

(1) Ukwahlukanisa okuhle: ngenxa yokuhlanzeka okuphezulu kwempushana ye-silicon, okuqukethwe kokungcola okuphansi, ukusebenza okuzinzile kanye nokufakwa kukagesi okuhle kakhulu, umkhiqizo olashiwe unokusebenza okuhle kokufakwa kwe-arc kanye nokumelana ne-arc.

(2) Inganciphisa izinga lokushisa eliphakeme le-exothermic lokuphendula okuphulukisayo kwe-epoxy resin, inciphise i-coefficient yokwandisa eqondile kanye nokuncipha komkhiqizo ophulukisiwe, ngaleyo ndlela iqede ukucindezeleka kwangaphakathi komkhiqizo ophulukisiwe futhi ivimbele ukuqhekeka.

(3) Ukumelana nokugqwala: I-silicon micro powder akulula ukusabela ngayo nezinye izinto, futhi ayisebenzi ngamakhemikhali ngama-acids amaningi nama-alkali. Izinhlayiya zayo zimbozwe ngokulinganayo ebusweni bento, ezinokumelana nokugqwala okuqinile.

(4) Ukugreda kosayizi wezinhlayiyana kunengqondo, okunganciphisa futhi kuqede ukucwiliswa kwenhlabathi nokuhlukanisa phakathi kokusetshenziswa; Ingathuthukisa amandla aqinile nacindezelayo womkhiqizo owelashiwe, ithuthukise ukumelana nokugqokwa, ikhulise ukuguquguquka kokushisa komkhiqizo olashiwe, futhi ikhulise ukubambezeleka komlilo.

(5) Impushana ye-silicon ephathwa nge-ejenti yokuhlanganisa i-silane inokumanzisa okuhle kuma-resin ahlukahlukene, ukusebenza kahle kwe-adsorption, ukuxutshwa kalula futhi akukho ukuhlanganisa.

(6) Ukwengezwa kwempushana ye-silica njengokugcwalisa ku-organic resin akuthuthukisi nje kuphela izakhiwo zomkhiqizo olashiwe, kodwa futhi kunciphisa izindleko zomkhiqizo.

Ukusetshenziswa okuyinhloko kwe-silicon powder:

(1) Isicelo ku-CCL: I-Silicon micro powder iwuhlobo lwesigcwali esisebenzayo. Ingakwazi ukuthuthukisa ukufakwa kwe-insulation, ukuqhutshwa kwe-thermal, ukuqina kokushisa, ukumelana ne-asidi ne-alkali (ngaphandle kwe-HF), ukumelana nokuhuzuka kanye nokuncipha komlilo we-CCL, ithuthukise amandla okugoba nokuzinza kwebhodi, inciphise izinga lokunwetshwa okushisayo kwebhodi, futhi ithuthukise i-dielectric njalo ye-CCL. Ngesikhathi esifanayo, i-silicon micro powder isetshenziswa kabanzi embonini ye-copper clad laminate ngenxa yezinto zayo zokusetshenziswa ezicebile kanye nentengo ephansi, enganciphisa izindleko ze-copper clad laminate.

(2) Ukusetshenziswa kwe-epoxy resin potting material: Njengenye yezigcwalisi ezivamile ze-epoxy resin potting material, i-silicon micro powder inendima esobala ekuthuthukiseni izici ezithile zomzimba ze-epoxy resin. Isibonelo, ukwengeza i-silicon micro powder esebenzayo ku-epoxy resin potting material kungathuthukisa kakhulu ukumelana nomthelela we-epoxy resin potting material futhi kunciphise i-viscosity ye-epoxy resin potting material.

(3) Isicelo ku-epoxy plastic sealant: i-epoxy molding compound (EMC), eyaziwa nangokuthi i-epoxy resin molding compound kanye ne-epoxy plastic sealant, iwuhlobo lwenhlanganisela yempushana exutshwe ne-epoxy resin njenge-matrix resin, i-phenolic resin esebenza kakhulu njenge-ejenti elaphayo, isigcwalisi njenge-silicon microitives, kanye nezinhlobonhlobo ze-add . Ekwakhekeni kwe-EMC, i-silicon powder iyona esetshenziswa kakhulu isigcwalisi, kanti isilinganiso sesisindo se-silicon powder kuya ku-epoxy molding compound singama-70% ~ 90%.

Inqubo yokukhiqiza ye-silicon micro powder ngokuvamile ifana komunye nomunye ngokuya ngezakhiwo ze-ore eluhlaza, inqubo ye-ore mineralogy nezinye izici kanye nezidingo zabasebenzisi zekhwalithi yomkhiqizo. Ukukhiqizwa kwe-high-purity superfine silicon powder kutholakala ngokuqhubekayo ukugaya noma ukuhlukaniswa kokugaya ngesisekelo sokulungiswa kwesihlabathi esihlanzekile. Ukukhethwa kwemishini yokucubungula kubaluleke kakhulu, ikakhulukazi ukukhethwa kwemishini yokugaya kanye nesigaba esiphezulu kakhulu. Ukukhethwa kwemishini yokugaya neyokuhlukanisa kahle kakhulu kuzothinta ngokuqondile ukukhishwa kanye nekhwalithi yemikhiqizo yokugcina kanye nokuma kwezinhlayiya zempushana. I-HCMilling(Guilin Hongcheng), njengomkhiqizi we-silicon micro powder grinding mill, i-HLMX silicon micro powder vertical mill yethu iyimishini ekahle yokukhiqiza i-ultra-fine silicon micro powder, enezinzuzo eziningi njengomthamo omkhulu, indawo ethile ephezulu, okuqukethwe okuphansi kokungcola, njll. ukusebenza kahle kokuhlukanisa impushana kuphezulu; Ikhanda elilodwa kanye nama-multi head powder concentrators asetshenziselwa ukulawula kahle ukucoleka kwemikhiqizo eqediwe; Ubuhle bomkhiqizo oqediwe busukela ku-3 μ M kuya ku-22 μ m. Izinhlobonhlobo zemikhiqizo efanelekayo ingatholakala.

Idatha ye-HCMi-silicon microimpushana yokugayaiphule ibhodlela lomthamo wezinye izigayo ezicwebe kakhulu njengezigayo ezivamile zokugeleza komoya kanye nezigayo zokudlidliza, ngokuphuma kwehora okungu-4-40t/h, futhi ukusetshenziswa kwamandla okuphansi kakhulu kunalokho komshini wokugaya ocoleke kakhulu. Kuyinto evumela imvelo futhi yonga amandlasilicon microimpushana yokugaya. Uma unezidingo ezifanele, sicela usithinte ukuze uthole imininingwane futhi usinikeze imininingwane elandelayo:
