Hmoov silicon micro yog cov khoom siv inorganic non-metallic uas tsis muaj tshuaj lom, tsis muaj saj thiab tsis muaj kuab paug, uas yog ua los ntawm cov quartz ntuj (SiO2) lossis fused quartz (amorphous SiO2 ntawm cov quartz ntuj tom qab kub siab yaj thiab txias) los ntawm kev sib tsoo, sib tsoo, flotation, pickling purification, kev kho dej huv siab thiab lwm yam txheej txheem. Cov hmoov silica siv dab tsi? HCMilling (Guilin Hongcheng) yog tus tsim khoom ntawmsilicon microlub tshuab sib tsoo hmoovCov hauv qab no piav qhia txog kev siv cov hmoov silicon micro:

Cov yam ntxwv ntawm silicon micro hmoov yog: refractive index 1.54-1.55, Mohs hardness txog 7, density 2.65g/cm3, melting point 1750 ℃, dielectric constant txog 4.6 (1MHz). Nws cov kev ua tau zoo tseem ceeb suav nrog:

(1) Kev rwb thaiv tsev zoo: vim yog qhov purity siab ntawm silicon hmoov, cov ntsiab lus tsis muaj kuab paug tsawg, kev ua haujlwm ruaj khov thiab kev rwb thaiv tsev hluav taws xob zoo heev, cov khoom kho tau muaj kev ua haujlwm rwb thaiv tsev zoo thiab arc tsis kam.

(2) Nws tuaj yeem txo qhov kub siab tshaj plaws ntawm qhov kev kho mob ntawm epoxy resin, txo cov coefficient nthuav dav thiab shrinkage ntawm cov khoom kho, yog li tshem tawm kev ntxhov siab sab hauv ntawm cov khoom kho thiab tiv thaiv kev tawg.

(3) Kev tiv thaiv corrosion: silicon micro hmoov tsis yooj yim rau kev cuam tshuam nrog lwm yam khoom, thiab tsis tshua muaj tshuaj lom neeg nrog feem ntau cov kua qaub thiab alkalis. Nws cov khoom me me tau npog sib npaug ntawm qhov chaw ntawm cov khoom, nrog kev tiv thaiv corrosion muaj zog.

(4) Qhov kev ntsuas qhov loj ntawm cov khoom me me yog qhov tsim nyog, uas tuaj yeem txo thiab tshem tawm cov av noo thiab stratification thaum siv; Nws tuaj yeem txhim kho lub zog tensile thiab compressive ntawm cov khoom kho, txhim kho qhov hnav tsis kam, ua rau muaj kev ua haujlwm thermal ntawm cov khoom kho, thiab ua rau muaj hluav taws kub ntau ntxiv.

(5) Cov hmoov silicon kho nrog silane coupling agent muaj qhov zoo wettability rau ntau yam resins, kev ua tau zoo adsorption, yooj yim sib tov thiab tsis muaj agglomeration.

(6) Qhov ntxiv ntawm silica hmoov ua cov khoom sau rau hauv cov organic resin tsis yog tsuas yog txhim kho cov khoom ntawm cov khoom kho, tab sis kuj txo cov nqi khoom.

Cov kev siv tseem ceeb ntawm cov hmoov silicon:

(1) Daim ntawv thov hauv CCL: Silicon micro hmoov yog ib hom khoom siv ua haujlwm. Nws tuaj yeem txhim kho qhov rwb thaiv tsev, thermal conductivity, thermal stability, acid thiab alkali tsis kam (tshwj tsis yog HF), abrasion tsis kam thiab nplaim taws retardancy ntawm CCL, txhim kho lub zog khoov thiab qhov ntev ntawm lub rooj tsavxwm, txo qhov thermal nthuav dav ntawm lub rooj tsavxwm, thiab txhim kho dielectric tas li ntawm CCL. Tib lub sijhawm, silicon micro hmoov yog siv dav hauv kev lag luam tooj liab clad laminate vim nws cov khoom siv raw nplua nuj thiab tus nqi qis, uas tuaj yeem txo tus nqi ntawm tooj liab clad laminate.

(2) Kev siv rau hauv cov khoom siv epoxy resin rau kev cog qoob loo: Raws li ib qho ntawm cov khoom siv epoxy resin rau kev cog qoob loo, silicon micro hmoov muaj lub luag haujlwm tseem ceeb hauv kev txhim kho qee yam khoom siv ntawm epoxy resin. Piv txwv li, kev ntxiv cov hmoov silicon micro rau hauv cov khoom siv epoxy resin rau kev cog qoob loo tuaj yeem txhim kho qhov kev tiv thaiv kev cuam tshuam ntawm cov khoom siv epoxy resin rau kev cog qoob loo thiab txo qhov viscosity ntawm cov khoom siv epoxy resin rau kev cog qoob loo.

(3) Daim ntawv thov hauv epoxy yas sealant: epoxy molding compound (EMC), tseem hu ua epoxy resin molding compound thiab epoxy yas sealant, yog ib hom hmoov molding compound sib xyaw nrog epoxy resin ua matrix resin, kev ua haujlwm siab phenolic resin ua tus neeg sawv cev curing, filler xws li silicon micro hmoov, thiab ntau yam additives. Hauv cov khoom ntawm EMC, silicon hmoov yog cov filler siv ntau tshaj plaws, thiab qhov hnyav piv ntawm silicon hmoov rau epoxy molding compound yog 70% ~ 90%.

Cov txheej txheem tsim cov hmoov silicon micro feem ntau zoo sib xws raws li cov yam ntxwv ntawm cov hlau nyoos, cov txheej txheem mineralogy thiab lwm yam ntxwv thiab cov kev xav tau ntawm cov neeg siv rau cov khoom zoo. Kev tsim cov hmoov silicon superfine siab yog tau los ntawm kev sib tsoo superfine ntxiv lossis kev sib tsoo kev faib tawm raws li kev npaj xuab zeb siab. Kev xaiv cov khoom siv ua haujlwm yog qhov tseem ceeb heev, tshwj xeeb tshaj yog kev xaiv cov khoom siv sib tsoo superfine thiab cov khoom siv faib tawm superfine. Kev xaiv cov khoom siv sib tsoo superfine thiab cov khoom siv faib tawm superfine yuav cuam tshuam ncaj qha rau cov zis thiab qhov zoo ntawm cov khoom kawg thiab cov duab ntawm cov hmoov me me. HCMilling (Guilin Hongcheng), ua tus tsim cov hmoov silicon micro sib tsoo zeb, peb lub HLMX silicon micro hmoov ntsug zeb yog cov khoom siv zoo tshaj plaws rau kev tsim cov hmoov silicon micro ultra-fine, uas muaj ntau yam zoo xws li muaj peev xwm loj, thaj chaw tshwj xeeb siab, cov ntsiab lus tsis huv qis, thiab lwm yam. Lub kaw lus faib tawm ntawm kev sib cais huab cua thib ob tau teeb tsa, thiab lub classifier thiab kiv cua raug tswj los ntawm kev hloov pauv zaus hloov pauv ceev, yog li qhov ua tau zoo ntawm kev sib cais hmoov yog siab; Ib lub taub hau thiab ntau lub taub hau hmoov concentrators siv los tswj qhov zoo ntawm cov khoom tiav; Qhov zoo ntawm cov khoom tiav lawm yog txij li 3 μ M txog 22 μ m.
