I-silica powder yenziwe nge-quartz yemvelo (SiO2) noma i-quartz ehlanganisiwe (i-amorphous SiO2 ngemva kwe-quartz yemvelo incibilika futhi ipholile ekushiseni okuphezulu) ngokuchotshozwa, ukugaya, ukuntanta, ukuhlanzwa kokugeza i-asidi, ukwelashwa kwamanzi ahlanzekile nezinye izinqubo.Ngakho-ke iyini inqubo yokusebenza nokukhiqiza kwe-silicon powder?Okulandelayo kuchaza ukusebenza kwe-silicon powder kanye nenqubo yokukhiqizai-siliconimpushana yokugaya.

Ngokungeziwe ku-coefficient ephansi yokwandisa okushisayo, impahla enhle kakhulu ye-dielectric, ukuqhutshwa kokushisa okuphezulu, ukusebenza kahle kokumiswa kanye nezinye izakhiwo ezinhle kakhulu, izakhiwo ze-silica powder nazo zihlanganisa okulandelayo:

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

(2) Inganciphisa izinga lokushisa eliphakeme le-exothermic le-epoxy resin curing reaction, inciphise i-linear expansion coefficient kanye nezinga lokuncipha komkhiqizo olashiwe, ngaleyo ndlela iqede ukucindezeleka kwangaphakathi komkhiqizo olashiwe futhi ivimbele ukuqhekeka.

(3) Ukumelana nokugqwala: i-silica powder akulula ukusabela ngayo nezinye izinto, futhi ayinakho ukusabela kwamakhemikhali nama-acid amaningi nama-alkali.Izinhlayiya zayo zimbozwe ngokulinganayo ebusweni bento, ezinokumelana nokugqwala okuqinile.

(4) Ukugreda kwezinhlayiyana kunengqondo, okunganciphisa futhi kuqede ukucwiliswa kwenhlabathi nokubeka izingqimba lapho kusetshenziswa;Ingathuthukisa amandla aqinile nacindezelayo womkhiqizo owelashiwe, ithuthukise ukumelana nokugqokwa, ikhulise ukuguquguquka kokushisa komkhiqizo olashiwe, futhi ikhulise ukubambezeleka komlilo.

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

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

Inqubo yokukhiqiza i-silica powder ihlanganisa ukugaya okomile nokugaya okumanzi.

Inqubo yokukhiqiza i-silicon powder yokugaya okomile: faka impahla eluhlaza ye-silicon powder kui-siliconinsimbiukugayaisigayoumshiniyokugaya.Inqubo yokugaya ingadla ngokuqhubekayo futhi ikhiphe, noma ifake izinto zokusetshenziswa ezinesisindo esiningi ngesikhathi esisodwa, bese ikhipha ngemva kokugaya okuqhubekayo izikhathi eziningana;Lapho ukhipha, usayizi wezinhlayiyana uzolawulwa isihlukanisi sempushana esihle.Imikhiqizo eqinile izobuyiselwa emshinini ukuze igaywe kabusha noma njengemikhiqizo, futhi imikhiqizo emihle izoba imikhiqizo.Ngokugaya okomile, lawula ngokuqinile umswakama wezinto zokugaya, futhi umkhiqizo ngeke wome.

Inqubo yokukhiqiza i-silica powder yokugaya okumanzi: faka inani lesisindo se-silica powder izinto zokusetshenziswa emshinini webhola ngesikhathi esisodwa, engeza inani elifanele lamanzi, futhi ukugxila kokusebenza kungu-65% ~ 80%;Ngemuva kokugaya okuqhubekayo amahora angaphezu kweshumi, uthele i-slurry, sebenzisa indlela yokuhlunga ingcindezi noma uyibeke emgqonyeni wezinto ezibonakalayo ukuze ugweme ngokwemvelo futhi uqede amanzi, futhi uthole ikhekhe lezinto ezithwala amanzi;Ngemva kokuphulwa nokuhlakazwa yi-crusher, ifakwa ngokulinganayo futhi ngokuqhubekayo ku-shaft engenalutho enyakazayo, futhi umkhiqizo utholakala ngemva kokoma.

Enqubweni yokukhiqiza yokugaya okomile kwe-silicon powder, i-silicon powder grinder yochwepheshe ingakhethwa.I-HLMXi-silicon powder ultra-fine mpoukugayaisigayoekhiqizwe i-HCMilling(Guilin Hongcheng) ingadlala indima enkulu enqubweni yokukhiqiza yokugaya okomile okuyi-silicon powder.Ngenxa yokusebenza kahle kwayo kokukhiqiza, ukunemba kwezigaba eziphezulu kanye nekhwalithi ephezulu yemikhiqizo yokugaya, izuze ukudunyiswa kwamakhasimende, futhi ifaneleka kakhulu njengeukukhiqizwa kwe-silicon powderumugqaimishini.

Njengomkhiqizi onolwazi wemishini yezimayini kanye nemishini, i-HCMilling(Guilin Hongcheng) igxile ekukhiqizeni izinhlobo ezahlukene zemishini.ukugaya i-silicon powderisigayoimishini.Uma ufuna ukwazi okwengeziwe ngenqubo yokukhiqiza i-silicon powder, sicela uthintane ne-HCM ukuze uthole ulwazi olwengeziwe.
