I-silicon powder encinci yinto engeyona inetyhefu, engenancasa kunye ne-pollution-free inorganic non-metallic material, eyenziwe nge-quartz yendalo (SiO2) okanye i-quartz edibeneyo (i-amorphous SiO2 ye-quartz yendalo emva kokunyibilika kobushushu obuphezulu kunye nokupholisa) ngokutyumza, ukugaya, ukujikeleza, ukuhlanjululwa kwe-pickling, ukucocwa kwamanzi aphezulu kunye nezinye iinkqubo zokucocwa kwamanzi. 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 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 nokuxhathisa kwe-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 rhoqo 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.

2 Ngokomzekelo, 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 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 yokusila i-mill, i-HLMX yethu ye-silicon i-micro powder vertical mill sisixhobo esifanelekileyo sokuvelisa i-ultra-fine silicon powder encinci, eneenzuzo ezininzi ezifana nomthamo omkhulu, indawo ethile ephezulu, umxholo ophantsi wokungcola, njl njl. 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-bume evumelana nokusingqongileyo kwaye yonga amandlasilicon microumgubo wokusila.
