Silicon micro powder ke ntho e se nang chefo, e sa latsoeheng le e se nang tšilafalo e se nang tšepe, e entsoeng ka quartz ea tlhaho (SiO2) kapa quartz e kopantsoeng (amorphous SiO2 ea quartz ea tlhaho ka mor'a ho qhibiliha ha mocheso o phahameng le ho pholile) ka ho senya, ho sila, flotation, pickling ho hloekisa, ho hloekisa metsi a hloekileng le mekhoa e meng.Tšebeliso ea phofo ea silika ke efe?HCMilling(Guilin Hongcheng) ke moetsi oasilicon e nyaneleloala la ho sila phofo.Lintlha tse latelang li hlalosa tšebeliso ea silicon micro powder:

Litšobotsi tsa silicon phofo e nyenyane ke: refractive index 1.54-1.55, Mohs hardness hoo e ka bang 7, density 2.65g/cm3, melting point 1750 ℃, dielectric constant about 4.6 (1MHz).Litšoantšiso tsa eona tse kholo li kenyelletsa:

(1) Ho kenya letsoho hantle: ka lebaka la bohloeki bo phahameng ba phofo ea silicon, lintho tse sa hloekang tse fokolang, ts'ebetso e tsitsitseng le ho kenya motlakase o babatsehang, sehlahisoa se phekotsoeng se na le ts'ebetso e ntle ea ho pata le ho hanyetsa arc.

(2) E ka fokotsa mocheso oa tlhōrō ea exothermic ea phekolo ea epoxy resin, e fokotsa sekhahla sa ho atolosa le ho fokotseha ha sehlahisoa se phekotsoeng, kahoo e felisa khatello ea ka hare ea sehlahisoa se phekotsoeng le ho thibela ho phunyeha.

(3) Corrosion resistance: silicon micro powder ha e bonolo ho sebetsana le lintho tse ling, 'me ha e sebetse ka lik'hemik'hale ka li-acids tse ngata le alkalis.Likaroloana tsa eona li koahetsoe ka ho lekana holim'a ntho, ka khanyetso e matla ea kutu.

(4) The particle size grading ke e utloahalang, e ka fokotsang le ho felisa sedimentation le stratification nakong ea tšebeliso;E ka ntlafatsa matla a ho tsieleha le a khatello ea sehlahisoa se folisitsoeng, ea ntlafatsa ho se sebetse hantle, ea eketsa ts'ebetso ea mocheso oa sehlahisoa se phekotsoeng, 'me ea eketsa ho lieha ha lelakabe.

(5) Phofo ea silicon e phekotsoeng ka silane coupling agent e na le metsi a matle ho li-resin tse fapaneng, ts'ebetso e ntle ea adsorption, ho kopanya habonolo ebile ha ho na motsoako.

(6) Ho eketsoa ha phofo ea silika e le ho tlatsa ka har'a resin ea tlhaho ha e ntlafatse feela thepa ea sehlahisoa se phekotsoeng, empa hape e fokotsa litšenyehelo tsa sehlahisoa.

Tšebeliso e ka sehloohong ea phofo ea silicon:

(1) Kopo ho CCL: Silicon micro powder ke mofuta oa filler e sebetsang.E ka ntlafatsa ho ts'oaroa, conductivity ea mocheso, botsitso ba mocheso, acid le alkali resistance (ntle le HF), ho hanyetsa abrasion le ho fokotseha ha lelakabe la CCL, ho ntlafatsa matla a ho khumama le botsitso ba boto, ho fokotsa sekhahla sa ho atolosa mocheso oa boto, le ho ntlafatsa dielectric constant tsa CCL.Ka nako e ts'oanang, phofo e nyane ea silicon e sebelisoa haholo indastering ea laminate ea koporo ka lebaka la thepa ea eona e tala le theko e tlase, e ka fokotsang litšenyehelo tsa laminate ea koporo.

(2) Tšebeliso ea lisebelisoa tsa epoxy resin potting: E ​​le e 'ngoe ea li-fillers tse tloaelehileng tsa epoxy resin potting material, silicon micro powder e na le karolo e totobetseng ea ho ntlafatsa litšobotsi tse ling tsa epoxy resin.Mohlala, ho eketsa phofo e nyane ea silicon ho epoxy resin potting material ho ka ntlafatsa haholo tshusumetso ya kganetso ya epoxy resin potting material le ho fokotsa viscosity ya epoxy resin potting material.

(3) Kopo ka epoxy plastic sealant: epoxy molding compound (EMC), e tsejoang hape e le epoxy resin molding compound le epoxy plastic sealant, ke mofuta oa motsoako oa phofo o kopantsoeng le epoxy resin e le matrix resin, high-performance phenolic resin e le sepheko, se tlatsang joalo ka silicon micro powder, le li-additives tse fapaneng.Sebopeho sa EMC, silicon powder ke eona e sebelisoang ka ho fetisisa ea ho tlatsa, 'me tekanyo ea boima ba silicon phofo ho motsoako oa epoxy molding ke 70% ~ 90%.

Ts'ebetso ea tlhahiso ea phofshoana e nyane ea silicon ka kakaretso e ts'oana ho ea ka thepa ea ore e tala, mineralogy ea ore process le litšobotsi tse ling le litlhoko tsa basebelisi bakeng sa boleng ba sehlahisoa.Tlhahiso ea phofshoana e phahameng ea superfine ea silicon e fumanoa ka ho sila ka mokhoa o phahameng ka ho fetisisa kapa ka lihlopha tsa ho sila motheong oa ho lokisetsa lehlabathe le hloekileng.Khetho ea lisebelisoa tsa ho lokisa e bohlokoa ka ho khetheha, haholo-holo khetho ea lisebelisoa tsa ho sila ka mokhoa o phahameng ka ho fetesisa le lisebelisoa tse hlophisitsoeng hantle.Khetho ea lisebelisoa tsa ho sila ka mokhoa o phahameng ka ho fetisisa le oa ho arola ka mokhoa o fetisisang o tla ama ka ho toba tlhahiso le boleng ba lihlahisoa tsa ho qetela le sebōpeho sa likaroloana tsa phofo.HCMilling(Guilin Hongcheng), joalo ka moetsi oa silicon e nyane ea phofo e silang leloala, leloala la rona la HLMX silicon micro powder vertical vertical leloala ke sesebelisoa se loketseng ho hlahisa phofo e nyane ea silicon e ntle haholo, e nang le melemo e mengata joalo ka matla a maholo, sebaka se phahameng se ikhethileng. lintho tse fokolang tse sa hloekang, joalo-joalo Tsamaiso ea lihlopha tsa karohano ea moea ea bobeli e lokiselitsoe, 'me lihlopha le fan li laoloa ke taolo ea lebelo la ho fetoha ha maqhubu, kahoo katleho ea karohano ea phofo e phahame;Hlooho e le 'ngoe le li-concentrators tse ngata tsa hlooho li sebelisoa ho laola ka katleho botle ba lihlahisoa tse felileng;Bokhabane ba sehlahisoa se felileng bo tloha ho 3 μ M ho isa ho 22 μ m.Mefuta e fapaneng ea lihlahisoa tse tšoanelehang e ka fumanoa.
