I-Silicon micro powder yinto engenabungozi, engenancasa kwaye engenangcoliseko, eyenziwe nge-quartz yendalo (i-SiO2) okanye i-quartz exutywe (i-SiO2 engabonakaliyo ye-quartz yendalo emva kokunyibilika nokupholisa kubushushu obuphezulu) ngokutyumza, ukugaya, ukudada, ukucocwa kwe-pickling, unyango lwamanzi olucocekileyo kakhulu kunye nezinye iinkqubo. Ziziphi iindlela zokusebenzisa i-silica powder? I-HCMilling (uGuilin Hongcheng) ngumvelisi we-HCMilling (uGuilin Hongcheng)i-silicon microumatshini wokugaya umguboOku kulandelayo kuchaza ukusetyenziswa kwe-silicon micro powder:

Iimpawu ze-silicon micro powder zezi: i-refractive index 1.54-1.55, ubunzima be-Mohs malunga ne-7, ubuninzi be-2.65g/cm3, i-melting point 1750 ℃, i-dielectric constant malunga ne-4.6 (1MHz). Imisebenzi yayo ephambili ibandakanya:

(1) Ubushushu obuhle: ngenxa yobunyulu obuphezulu bomgubo we-silicon, umxholo ophantsi wokungcola, ukusebenza okuzinzileyo kunye nobushushu obuhle bombane, imveliso ephilisiweyo inobushushu obuhle kunye nokumelana ne-arc.

(2) Inokunciphisa ubushushu obuphezulu be-exothermic yempendulo yokupholisa ye-epoxy resin, inciphise i-coefficient yokwandiswa okuthe ngqo kunye nokuncipha kwemveliso ephilisiweyo, ngaloo ndlela isusa uxinzelelo lwangaphakathi lwemveliso ephilisiweyo kwaye ithintele ukuqhekeka.

(3) Ukumelana nokugqwala: i-silicon micro powder ayilulanga ukusabela nezinye izinto, kwaye ayisabelani ngokweekhemikhali kunye nee-asidi ezininzi kunye nee-alkali. Amasuntswana ayo agqunywe ngokulinganayo phezu komphezulu wento, enokumelana nokugqwala okunamandla.

(4) Ukuhlelwa kobukhulu beesuntswana kufanelekile, okunokunciphisa nokuphelisa ukubola kunye nokuqhekeka ngexesha lokusetyenziswa; Kunokuphucula amandla okuxinana kunye nokucinezelwa kwemveliso ephilisiweyo, kuphucule ukumelana nokuguguleka, kunyuse ukuhanjiswa kobushushu kwemveliso ephilisiweyo, kwaye kunyuse ukubandezeka komlilo.

(5) Umgubo we-silicon ophathwe nge-silane coupling agent unamandla okumanzisa kwiiresini ezahlukeneyo, ukusebenza kakuhle kokufunxa, kulula ukuwuxuba kwaye akukho kuhlangana.

(6) Ukongezwa komgubo we-silica njengesizalisi kwi-resin yendalo akupheleli nje ekuphuculeni iimpawu zemveliso ecociweyo, kodwa kukwanciphisa neendleko zemveliso.

Iindlela eziphambili zokusetyenziswa komgubo we-silicon:

(1) Ukusetyenziswa kwi-CCL: I-silicon micro powder luhlobo lwe-filler esebenzayo. Ingaphucula ukugquma, ukuqhuba kobushushu, ukuzinza kobushushu, ukumelana ne-asidi kunye ne-alkali (ngaphandle kwe-HF), ukumelana nokukrweleka kunye nokungawi ilangabi kwe-CCL, iphucule amandla okugoba kunye nokuzinza kobukhulu bebhodi, inciphise izinga lokwanda kobushushu bebhodi, kwaye iphucule i-dielectric constant ye-CCL. Kwangaxeshanye, i-silicon micro powder isetyenziswa kakhulu kwishishini le-laminate egqunywe ngobhedu ngenxa yezinto zayo eziluhlaza ezityebileyo kunye nexabiso eliphantsi, elinokunciphisa iindleko ze-laminate egqunywe ngobhedu.

(2) Ukusetyenziswa kwezinto zokufaka i-epoxy resin: Njengenye yezinto eziqhelekileyo zokuzalisa izinto zokufaka i-epoxy resin, i-silicon micro powder inendima ebonakalayo ekuphuculeni ezinye iipropati zomzimba ze-epoxy resin. Umzekelo, ukongeza i-silicon micro powder esebenzayo kwizinto zokufaka i-epoxy resin kunokuphucula kakhulu ukumelana nempembelelo kwezinto zokufaka i-epoxy resin kwaye kunciphise i-viscosity yezinto zokufaka i-epoxy resin.

(3) Ukusetyenziswa kwi-epoxy plastic sealant: i-epoxy molding compound (EMC), eyaziwa ngokuba yi-epoxy resin molding compound kunye ne-epoxy plastic sealant, luhlobo lwe-powder molding compound exutywe ne-epoxy resin njenge-matrix resin, i-phenolic resin esebenza kakhulu njenge-curing agent, i-filler efana ne-silicon micro powder, kunye nezinye izinto ezahlukeneyo. Kwi-EMC, i-silicon powder yeyona filler isetyenziswa kakhulu, kwaye umlinganiselo wobunzima be-silicon powder kwi-epoxy molding compound yi-70% ~ 90%.

Inkqubo yokuvelisa i-silicon micro powder ngokubanzi iyafana ngokweempawu ze-ore eluhlaza, i-ore process mineralogy kunye nezinye iimpawu kunye neemfuno zabasebenzisi zomgangatho wemveliso. Ukuveliswa kwe-high-purity superfine silicon powder kufunyanwa ngokugrumba okanye ukugrumba ngakumbi ngokusekelwe ekulungiseleleni isanti ecocekileyo kakhulu. Ukukhethwa kwezixhobo zokucubungula kubaluleke kakhulu, ngakumbi ukukhethwa kwezixhobo zokugaya ezingcono kakhulu kunye nokugrumba. Ukukhethwa kwezixhobo zokugaya ezingcono kakhulu kunye nokugrumba kuya kuchaphazela ngokuthe ngqo imveliso kunye nomgangatho weemveliso zokugqibela kunye nokuma kwamasuntswana e-powder. I-HCMilling (Guilin Hongcheng), njengomvelisi we-silicon micro powder grinding mill, i-HLMX silicon micro powder vertical mill yethu sisixhobo esifanelekileyo sokuvelisa i-ultra-fine silicon micro powder, enezibonelelo ezininzi ezifana nomthamo omkhulu, indawo ephezulu ethile, umxholo wokungcola okuphantsi, njl. Inkqubo yokwahlulahlula umoya wesibini iyacwangciswa, kwaye i-classifier kunye nefeni zilawulwa ngumgaqo wesantya sokuguqulwa kwamaza, ngoko ke ukusebenza kakuhle kokwahlulwa komgubo kuphezulu; Ii-single head kunye ne-multi head powder concentrators zisetyenziselwa ukulawula ngokufanelekileyo ubunono beemveliso ezigqityiweyo; Ubunzima bemveliso egqityiweyo buqala kwi-3 μ M ukuya kwi-22 μ m. Iintlobo ngeentlobo zeemveliso ezifanelekileyo zinokufunyanwa.

IiHCMi-silicon microumatshini wokugaya umguboiphumelele kwiingxaki zezinye ii-mill ezicolekileyo kakhulu ezifana ne-air flow mill yendabuko kunye ne-vibration mill, ekhupha i-4-40t/h ngeyure, kwaye ukusetyenziswa kwamandla kuphantsi kakhulu kunezixhobo ezifanayo zokugaya ezicolekileyo kakhulu. Yindlela enobuhlobo nokusingqongileyo kwaye igcina amandla.si-icon microumatshini wokugaya umguboUkuba uneemfuno ezifanelekileyo, nceda unxibelelane nathi ukuze ufumane iinkcukacha kwaye usinike ulwazi olulandelayo:
