Silicon micro poda isiri-chepfu, isinganakidze uye isina kusvibiswa-isina inorganic isiri-metallic zvinhu, iyo inogadzirwa neakasikwa quartz (SiO2) kana yakasanganiswa quartz (amorphous SiO2 yeasiki quartz mushure mekunyungudika kwekushisa uye kutonhora) kuburikidza nekupwanya, kugaya, flotation, pickling purification, high-purity water treatment uye mamwe maitiro.Ndezvipi zvinoshandiswa zve silica powder?HCMilling(Guilin Hongcheng) ndiye mugadziri wesilicon microguyo rekukuya.Izvi zvinotevera zvinotsanangura kushandiswa kwesilicon micro powder:

Hunhu hwesilicon micro poda ndeiyi: refractive index 1.54-1.55, Mohs kuoma anenge 7, density 2.65g/cm3, melting point 1750 ℃, dielectric constant about 4.6 (1MHz).Kuita kwayo kukuru kunosanganisira:

(1) Kuvharira kwakanaka: nekuda kwekuchena kwakanyanya kwesilicon poda, kuderera kwemukati, kushanda kwakadzikama uye yakanakisa kuvharisa magetsi, chigadzirwa chakarapwa chine yakanaka insulation performance uye arc kuramba.

(2) Inogona kuderedza exothermic peak tembiricha yekurapa maitiro epoxy resin, kuderedza mutsara wekuwedzera coefficient uye shrinkage yechigadzirwa chakarapwa, nokudaro kubvisa kushushikana kwemukati kwechigadzirwa chakarapwa uye kudzivirira kuputika.

(3) Corrosion resistance: silicon micro poda haisi nyore kuita nezvimwe zvinhu, uye haibatike mumakemikari neakawanda acids uye alkalis.Zvimedu zvaro zvakafukidzwa zvakaenzana pamusoro pechinhu, nekudzivirira kwakasimba kwekuora.

(4) Iyo particle size grading inonzwisisika, iyo inogona kuderedza uye kubvisa sedimentation uye stratification panguva yekushandiswa;Inogona kukwidziridza kusimba uye kumanikidza kwechigadzirwa chakarapwa, kunatsiridza kupfeka kuramba, kuwedzera kupisa kwechigadzirwa chakarapwa, uye kuwedzera murazvo wemoto.

(5) Iyo silicon poda yakabatwa ne silane coupling agent ine yakanaka wettability kune akasiyana resin, yakanaka adsorption performance, nyore kusanganisa uye hapana agglomeration.

(6) Kuwedzerwa kwe silica poda sekuzadza mukati meiyo organic resin hakungonatsiridza zvimiro zvechigadzirwa chakarapwa, asi zvakare kunoderedza mutengo wechigadzirwa.

Kushandiswa kukuru kwesilicon powder:

(1) Kushandisa muCCL: Silicon micro poda imhando yekushanda kwekuzadza.Inogona kuvandudza kuvharidzira, kupisa kwekushisa, kugadzikana kwemafuta, asidhi uye alkali kuramba (kunze kweHF), abrasion kuramba uye kudzoreredza kwemurazvo weCCL, kuvandudza simba rekukotama uye kugadzikana kwebhodhi, kuderedza kupisa kwekuwedzera kwebhodhi, uye kuvandudza dielectric nguva dzose yeCCL.Panguva imwecheteyo, silicon micro powder inoshandiswa zvakanyanya mumhangura yakavhara laminate indasitiri nekuda kwehupfumi hwayo hwekushandisa uye yakaderera mutengo, iyo inogona kuderedza mutengo wemhangura clad laminate.

(2) Kushandisa mu epoxy resin potting zvinhu: Seimwe yeanowanzo kuzadza epoxy resin potting material, silicon micro poda ine basa riri pachena mukuvandudza mamwe maitiro epoxy resin.Semuenzaniso, kuwedzera inoshanda silicon diki poda kune epoxy resin potting zvinhu zvinogona kuvandudza zvakanyanya kupikisa kwe epoxy resin potting zvinhu uye kuderedza viscosity ye epoxy resin potting zvinhu.

(3) Kushandiswa mu epoxy plastic sealant: epoxy molding compound (EMC), inozivikanwawo se epoxy resin molding compound uye epoxy plastic sealant, imhando yepowder molding compound yakasanganiswa ne epoxy resin se matrix resin, high-performance phenolic resin se iyo inoporesa mumiririri, yekuzadza senge silicon micro poda, uye akasiyana ekuwedzera.Mukuumbwa kweEMC, silicon poda ndiyo inonyanya kushandiswa kuzadza, uye huremu hwesilicon powder kune epoxy molding compound i70% ~ 90%.

Iyo nzira yekugadzira yesilicon micro poda inowanzofanana kune imwe neimwe zvichienderana nemaitiro eiyo mbishi ore, ore process mineralogy uye humwe hunhu uye zvinodikanwa zvevashandisi zvemhando yechigadzirwa.Kugadzirwa kwepamusoro-kuchena superfine silicon poda kunowanikwa nekuwedzera kwepamusoro-soro kukuya kana kugaya kupatsanurwa pahwaro hwepamusoro-kuchena kugadzirira jecha.Kusarudzwa kwemidziyo yekugadzira kwakakosha zvakanyanya, kunyanya kusarudzwa kwepamusoro-soro kugaya uye superfine classification michina.Sarudzo yeyakanyanya kukuya uye yepamusoro-soro yemhando yemidziyo inokanganisa zvakananga kubuda uye kunaka kwezvigadzirwa zvekupedzisira uye chimiro chehupfu.HCMilling(Guilin Hongcheng), semugadziri wesilicon micro powder grinding mill, yedu HLMX silicon micro powder vertical mill ndiyo yakanakira kugadzira ultra-fine silicon micro poda, ine zvakawanda zvakanakira senge hombe, yakakwira chaiyo nzvimbo, kuderera kwehutsvina hutsika, etc. Iyo yemhando yegadziriro yekuparadzanisa kwemhepo yechipiri inogadziriswa, uye iyo classifier uye fan inodzorwa neiyo frequency kutendeuka kukurumidza kudzora, saka hupfu hwekuparadzanisa hunobudirira hwakakwirira;Musoro mumwechete uye akawanda musoro poda concentrators anoshandiswa kudzora zvinobudirira kunaka kwezvakapedzwa zvigadzirwa;Fineness yechigadzirwa chakapedzwa kubva pa3 μ M kusvika 22 μ m.Zvigadzirwa zvakasiyana-siyana zvinokodzera zvinogona kuwanikwa.

Zvikwata zveHCMsilicon microguyo rekukuyayatyora bhodhoro rezvimwe zvigayo zvemhando yepamusoro-soro sechigayo chekuyerera kwemhepo uye vibration mill, ine kubuda kweawa imwe ye4-40t/h, uye mashandisirwo esimba akadzikira zvakanyanya kupfuura aya emidziyo yekukuya.Iyo inzvimbo-inoshamwaridzana uye inochengetedza simbasilicon microguyo rekukuya.Kana iwe uine zvinodiwa, tapota taura nesu kuti uwane ruzivo uye upe ruzivo rwekutevera kwatiri:
