Silicon yaying'ono ufa ndi zinthu zopanda poizoni, zopanda pake komanso zopanda chitsulo, zomwe zimapangidwa ndi quartz yachilengedwe (SiO2) kapena quartz yosakanikirana (amorphous SiO2 ya quartz yachilengedwe pambuyo pa kutentha kwambiri kusungunuka ndi kuzizira) kudzera mukuphwanya, kugaya, flotation, pickling kuyeretsedwa, mkulu-chiyero madzi mankhwala ndi njira zina.Kodi silika ufa amagwiritsidwa ntchito bwanji?HCMilling(Guilin Hongcheng) ndi wopangasilicon microufa mphero.Zotsatirazi zikufotokozera kugwiritsa ntchito silicon micro powder:

Makhalidwe a silicon yaying'ono ufa ndi: refractive index 1.54-1.55, Mohs kuuma pafupifupi 7, kachulukidwe 2.65g/cm3, melting point 1750 ℃, dielectric constant about 4.6 (1MHz).Zochita zake zazikulu ndi izi:

(1) Kutchinjiriza kwabwino: chifukwa cha chiyero chachikulu cha ufa wa silicon, zonyansa zochepa, magwiridwe antchito okhazikika komanso kutchinjiriza kwamagetsi kwabwino, chinthu chochiritsidwa chimakhala ndi ntchito yabwino yotchinjiriza komanso kukana kwa arc.

(2) Ikhoza kuchepetsa kutentha kwakukulu kwa kutentha kwa machiritso a epoxy resin, kuchepetsa kukula kwa epoxy coefficient ndi shrinkage ya mankhwala ochiritsidwa, motero kuthetsa kupsinjika kwa mkati mwa mankhwala ochiritsidwa ndikupewa kusweka.

(3) Kukana kwa dzimbiri: silicon yaying'ono ufa sikophweka kuchita ndi zinthu zina, ndipo samachita mankhwala ndi zidulo zambiri ndi alkalis.Tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono tating'onoting'ono.

(4) The tinthu kukula masanjidwe ndi wololera, amene angathe kuchepetsa ndi kuthetsa sedimentation ndi stratification pa ntchito;Itha kupititsa patsogolo kulimba komanso kulimba kwa chinthu chochiritsidwa, kukulitsa kukana kwamafuta, kukulitsa matenthedwe azinthu zomwe zachiritsidwa, ndikuwonjezera kuchedwa kwamoto.

(5) Ufa wa silicon wothiridwa ndi silane wolumikizana ndi wothandizila umakhala wonyowa bwino ku utomoni wosiyanasiyana, magwiridwe antchito abwino a adsorption, kusakaniza kosavuta komanso osaphatikiza.

(6) Kuphatikizika kwa ufa wa silika ngati chodzaza mu utomoni wa organic sikungowonjezera zinthu zomwe zachiritsidwa, komanso kumachepetsa mtengo wazinthu.

Ntchito zazikulu za silicon powder:

(1) Kugwiritsa ntchito mu CCL: Silicon yaying'ono ufa ndi mtundu wodzaza ntchito.Itha kusintha kutchinjiriza, matenthedwe matenthedwe, kukhazikika kwamafuta, kukana kwa asidi ndi alkali (kupatula HF), kukana kwa abrasion ndi kuchepa kwamoto kwa CCL, kupititsa patsogolo mphamvu yopindika ndi kukhazikika kwa board, kuchepetsa kuchuluka kwa bolodi, ndikusintha ma dielectric pafupipafupi a CCL.Pa nthawi yomweyo, pakachitsulo yaying'ono ufa chimagwiritsidwa ntchito mkuwa atavala laminate makampani chifukwa olemera zipangizo zopangira ndi mtengo wotsika, amene akhoza kuchepetsa mtengo wa copper clad laminate.

(2) Kugwiritsa ntchito mu epoxy utomoni potting zakuthupi: Monga imodzi mwa fillers wamba wa epoxy utomoni potting zakuthupi, pakachitsulo yaying'ono ufa ali ndi udindo wodziwikiratu kusintha zina thupi epoxy utomoni.Mwachitsanzo, kuwonjezera silicon yaying'ono ufa ku epoxy utomoni potting zakuthupi kungathandize kwambiri kukana kwa epoxy utomoni potting zakuthupi ndi kuchepetsa mamasukidwe akayendedwe a epoxy utomoni potting zakuthupi.

(3) Ntchito mu epoxy pulasitiki sealant: epoxy akamaumba pawiri (EMC), amatchedwanso epoxy utomoni akamaumba pawiri ndi epoxy pulasitiki sealant, ndi mtundu wa ufa akamaumba pawiri kusakaniza epoxy utomoni monga masanjidwewo utomoni, mkulu-ntchito phenolic utomoni monga machiritso, zodzaza monga silicon micro powder, ndi zina zowonjezera.Pakupangidwa kwa EMC, silicon ufa ndizomwe zimagwiritsidwa ntchito kwambiri, ndipo kulemera kwa silicon ufa ku epoxy akamaumba pawiri ndi 70% ~ 90%.

Njira yopanga silicon yaying'ono ufa nthawi zambiri imakhala yofanana wina ndi mnzake malinga ndi momwe amapangira ore yaiwisi, ore process mineralogy ndi mawonekedwe ena komanso zofunikira za ogwiritsa ntchito pamtundu wazinthu.Kupanga kwapamwamba-kuyera kwapamwamba kwa silicon ufa kumapezedwa ndi kugaya kopitilira muyeso kapena kugawika kwamagulu pamaziko a kukonzekera kwa mchenga wapamwamba kwambiri.Kusankhidwa kwa zida zogwirira ntchito ndikofunikira kwambiri, makamaka kusankha kwapamwamba kwambiri komanso zida zamagulu apamwamba kwambiri.Kusankhidwa kwa superfine akupera ndi superfine classification zida zidzakhudza mwachindunji linanena bungwe ndi khalidwe la mankhwala omaliza ndi mawonekedwe a particles ufa.HCMilling(Guilin Hongcheng), monga Mlengi wa pakachitsulo yaying'ono ufa akupera mphero, HLMX wathu pakachitsulo yaying'ono ufa ofukula mphero ndi zipangizo abwino kubala kopitilira muyeso-chabwino pakachitsulo kakang'ono ufa, amene ali ndi ubwino ambiri monga mphamvu yaikulu, mkulu enieni pamwamba m'dera, zonyansa zochepa, ndi zina zotero. Dongosolo la kugawanika kwa mpweya wachiwiri limakonzedwa, ndipo gulu ndi fanizi zimayendetsedwa ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kakeMutu umodzi ndi mitu yambiri yophatikizira ufa imagwiritsidwa ntchito kuwongolera bwino zinthu zomalizidwa;Ubwino wa zinthu zomalizidwa umachokera ku 3 μM mpaka 22 μm.Zogulitsa zosiyanasiyana zoyenerera zitha kupezeka.

Zithunzi za HCMsilicon microufa mpheroyathyola mphamvu ya mphero zina zotsogola bwino kwambiri monga mphero zachikhalidwe zakutulutsa mpweya ndi vibration, zomwe zimatuluka paola 4-40t/h, komanso kugwiritsa ntchito mphamvu kutsika kwambiri kuposa zida zofananira zofananira bwino kwambiri.Ndi malo ochezeka komanso opulumutsa mphamvusilicon microufa mphero.Ngati muli ndi zofunikira, chonde titumizireni kuti mumve zambiri ndikutipatsa zambiri:
