I-Silicon i-powder encinci yinto engeyona ityhefu, engenancasa kunye ne-inorganic-free non-metallic material, eyenziwe nge-quartz yendalo (i-SiO2) okanye i-quartz edibeneyo (i-amorphous SiO2 ye-quartz yendalo emva kokunyibilika kobushushu obuphezulu kunye nokupholisa) ngokutyumza, ukugaya, i-flotation, ukucocwa kokucoca, ukucocwa kwamanzi aphezulu kunye nezinye iinkqubo.Ziziphi izinto ezisetyenziselwa umgubo we-silica?HCMilling(Guilin Hongcheng) na umenzi wei-silicon microumgubo wokusila.Oku kulandelayo kuchaza ukusetyenziswa kwe-silicon powder encinci:

Iimpawu ze-silicon powder ezincinci zezi: isalathisi se-refractive 1.54-1.55, i-Mohs yobunzima malunga ne-7, ubuninzi be-2.65g / cm3, i-melting point 1750 ℃, i-dielectric rhoqo malunga ne-4.6 (1MHz).Eyona midlalo iphambili ibandakanya:

(1) Ukugquma okulungileyo: ngenxa yokucoceka okuphezulu komgubo we-silicon, umxholo wokungahlambuluki ophantsi, ukusebenza okuzinzileyo kunye nokufakelwa kombane okugqwesileyo, imveliso ephilisiweyo inokusebenza kakuhle kokugquma kunye nokumelana ne-arc.

(2) Inokunciphisa ubushushu obuphezulu be-exothermic yempendulo yokuphilisa ye-epoxy resin, ukunciphisa i-coefficient yokwandisa umgca kunye nokunciphisa imveliso ephilisiwe, ngaloo ndlela ikhuphe uxinzelelo lwangaphakathi lwemveliso ephilisiwe kunye nokuthintela ukuqhekeka.

(3) Ukumelana nokubola: i-silicon ipowder encinci ayilula ukusabela kunye nezinye izinto, kwaye ayisebenzi ngamachiza kunye ne-acids ezininzi kunye ne-alkali.Amasuntswana ayo agqunywe ngokulinganayo kumphezulu wento, enokumelana nokugqwala okuqinileyo.

(4) Ukuhlelwa kobungakanani besuntswana kunengqiqo, enokunciphisa kunye nokuphelisa intlenga kunye ne-stratification ngexesha lokusetyenziswa;Inokonyusa amandla okuqina kunye noxinzelelo lwemveliso enyangisiweyo, iphucule ukuxhathisa ukunxitywa, yonyusa ubushushu bemveliso enyangisiweyo, kwaye yonyuse ukubuyiswa komlilo.

(5) I-silicon powder ephathwa nge-agent yokudibanisa i-silane inokumanzisa okulungileyo kwii-resin ezahlukeneyo, ukusebenza kakuhle kwe-adsorption, ukuxuba okulula kwaye akukho agglomeration.

(6) Ukongezwa kwe-silica powder njenge-filler kwi-organic resin ayiphuculi nje kuphela iimpawu zemveliso ephilisiwe, kodwa kunciphisa iindleko zemveliso.

Ukusetyenziswa okuphambili kwe-silicon powder:

(1) Isicelo kwi-CCL: I-Silicon i-powder powder luhlobo oluthile lokuzaliswa okusebenzayo.Inokuphucula ukugquma, ukuguquguquka kwe-thermal, ukuzinza kwe-thermal, i-asidi kunye nokumelana ne-alkali (ngaphandle kwe-HF), ukuxhathisa i-abrasion kunye ne-flame retardancy ye-CCL, ukuphucula amandla okugoba kunye nokuzinza kwebhodi, ukunciphisa izinga lokwandiswa kwebhodi, kunye nokuphucula i-dielectric constant ye-CCL.Ngelo xesha, i-silicon powder powder isetyenziswa ngokubanzi kwishishini le-laminate ye-copper clad ngenxa yezinto zayo ezityebileyo kunye nexabiso eliphantsi, elinokunciphisa ixabiso le-laminate ye-copper clad.

2Ngokomzekelo, ukongeza i-silicon powder esebenzayo kwi-epoxy resin potting material inokuphucula kakhulu ukuchasana kwe-epoxy resin potting material kunye nokunciphisa i-viscosity ye-epoxy resin potting material.

3 iarhente yokunyanga, isihluzi esinje ngesilicon umgubo omncinci, kunye neentlobo ngeentlobo zezongezo.Ekubunjweni kwe-EMC, i-silicon powder yeyona nto isetyenziswayo ukuzalisa, kunye nomlinganiselo we-silicon powder kwi-epoxy molding compound yi-70% ~ 90%.

Inkqubo yokuvelisa i-silicon powder encinci ifana ngokubanzi enye kwenye ngokweempawu ze-ore ekrwada, inkqubo ye-ore mineralogy kunye nezinye iimpawu kunye neemfuno zabasebenzisi bomgangatho wemveliso.Ukuveliswa komgubo we-silicon ococekileyo ococekileyo ufunyanwa ngokusila ngokucokisekileyo okanye ukwahlulahlula ngokwesiseko sokulungiswa kwesanti ecocekileyo.Ukukhethwa kwezixhobo zokucubungula kubaluleke kakhulu, ngakumbi ukukhethwa kwezixhobo zokusila ezicolekileyo kunye nezixhobo zokuhlelwa kwe-superfine.Ukukhethwa kwezixhobo zokusila ngokugqithiseleyo kunye ne-superfine classifications ziya kuchaphazela ngokuthe ngqo imveliso kunye nomgangatho weemveliso zokugqibela kunye nokuma kweengqungquthela ze powder.I-HCMilling (i-Guilin Hongcheng), njengomvelisi we-silicon micro powder grinding mill, i-HLMX yethu ye-silicon ipowder encinci ye-powder vertical mill sisixhobo esifanelekileyo sokuvelisa i-ultra-fine silicon powder micro, eneenzuzo ezininzi ezifana nomthamo omkhulu, indawo ephezulu yendawo ethile, umxholo ophantsi wokungcola, njl njl. Inkqubo yokwahlulahlula umoya wesibini iqwalaselwe, kwaye umdidi kunye nefeni zilawulwa ngummiselo wesantya sokuguqulwa kwamaza, ngoko ke ukusebenza kakuhle kokwahlula umgubo kuphezulu;Intloko enye kunye neentloko ezininzi ze powder concentrators zisetyenziselwa ukulawula ngokufanelekileyo ukucolwa kweemveliso ezigqityiweyo;Ukulunga kweemveliso ezigqityiweyo zivela kwi-3 μ M ukuya kwi-22 μ m.Iintlobo ngeentlobo zeemveliso ezifanelekileyo zinokufumaneka.

IiHCM zei-silicon microumgubo wokusilaugqobhoze kumthamo webhotile yezinye ii-ultra-fine mill ezifana ne-air flow flow mill yesiqhelo kunye ne-vibration mill, kunye nemveliso yeyure ye-4-40t / h, kunye nokusetyenziswa kwamandla okungaphantsi kakhulu kunezixhobo zokusila ezifanayo.Yimeko evumelana nokusingqongileyo kwaye igcina amandlasilicon microumgubo wokusila.Ukuba uneemfuno ezifanelekileyo, nceda uqhagamshelane nathi ngeenkcukacha kwaye unikezele ngolwazi olulandelayo kuthi:
