Cov hmoov silica zoo tib yam yog qhov inorganic, tsis yog} Nws muaj cov tshuaj lom neeg zoo heev, siab tawv, tsis muaj kev nthuav dav thermal, thiab cov rwb thaiv tsev zoo, ua lub luag haujlwm tseem ceeb hauv ntau daim teb.
Cov yam ntxwv yooj yim
Cov hmoov silica decica zoo tib yam tshwm sim raws li lub ntsej muag dawb lossis tawm - cov hmoov dawb nrog cov hmoov av lossis tsis tu ncua polyhedral. Nws cov particle loj faib ntau yog dav thiab tuaj yeem hloov kho rau micron lossis txawm tias cov theem submicron nyob ntawm daim ntawv thov. Nws muaj mohs hardness ntawm 7 thiab ib qhov ntom ntom ntawm kwv yees li 2.65 g / cm³. Nws tseem muaj cov thermal tsawg conductivity thiab thermal expansion coefficient, thiab cov khoom ua pov thawj zoo heev, tseem ruaj nyob rau ntawm qhov kub ntawm 800℃thiab 1000 degree. Tsis tas li ntawd, Silica hmoov muaj cov roj nqus tau tsawg thiab zoo dispersibility, cia nws los tsim cov teeb meem ruaj khov nrog ntau yam ntawm cov resins, txhuam, thiab ceramic matrices.
Cov txheej txheem ntau lawm
Kev tsim khoom ntawm silica micropowder feem ntau koom nrog cov kauj ruam hauv qab no:
1.Rawb cov khoom xaiv: high - cov ntsiab lus ntawm cov ntsiab lus ntawm cov ntsiab lus xws li hlau, txhuas, thiab calcium.
2.Crushing sib tsoo thiab sib tsoo txhav: tshuab crushing yog siv los pib sib tsoo cov khoom siv raw, ua raws li cov khoom loj me me uas siv cov pob milling lossis raymond milling.
3.purification: acid ntxuav, sib cais sib cais, lossis cov flotation yog siv los tshem tawm cov metallic impurities thiab txhim kho cov khoom siv dawb thiab dawb.
4.GRAADING THIAB NTIM: Paus Me Tshaj Tawm yog tswj tau siv Airflow, thiab thaum kawg, tom qab dhau kev sim, cov khoom yog ntim thiab ntim.
Cov ntawv thov MAIN
1. Hauv Ntim Ntim Ntim
Hauv kev lag luam hluav taws xob, silica micropowder tau siv dav ua ib tug muab tub lim dej (EMC), tooj liab clad laminate (ccc), thiab tshuab hluav taws xob hauv hluav taws xob. Nws qhov kev sib sau tau yooj yim txhim kho cov thermal conductivity, noo noo tsis kam, thiab suav nrog kev ruaj ntseg thiab kev ntseeg tau ntawm cov hluav taws xob.
2. Cov txheej txheem thiab xim av
Silica hmoov tuaj yeem siv los ua kev ua haujlwm ua haujlwm hauv anti {{} Cov txheej corrosion, txhim kho txheej txheej hardness, corrosion tsis kam, thiab huab cua tsis kam. Nws cov roj av qis thiab zoo dispersibilibility pab kom zoo txheej rheatoral cov khoom thiab txo sedimentation.
3. Refractory cov ntaub ntawv thiab Ceramics
Vim nws qhov siab tshaj plaws - qhov kub thiab txias, cov khoom siv ua kom zoo nkauj, cov khoom siv sib xyaw ua ke los txhim kho hauv cov khoom siv ntom ntom nti, thermal poob siab kuj, thiab lub neej pabcuam.
4. Roj hmab thiab plastics
Hauv cov roj hmab kev lag luam, silica hmoov tuaj yeem siv los ua cov khoom siv txhawb nqa lossis txuas ntxiv txhim kho txoj kev tiv thaiv, kua muag ruaj khov, ruaj khov ntawm cov khoom roj hmab. Nyob rau hauv lub plastics kev lag luam, nws tuaj yeem txhim kho lub rigidity ntawm cov khoom siv sib xyaw, txo cov shrinkage, thiab txhim kho lub tshuab cua kub.
Cov Qauv Zoo thiab Kev Ua Haujlwm
Cov Silica medica Micropowder yog feem ntau muab cais rau qib sib txawv, xws li qib electronic, thiab txheej txheej. Industrial {-}}}}}}}}}}}}}}}}}}}}} dua cov kev xav tau qis dua (sioter ntau dua li 98%) thiab yog haum rau kev lag luam xws li cov ntaub ntawv tsim thiab ua pov thawj. Hluav taws xob {{{}}}}}} ion cov qauv (sioter ntau dua los yog coloride ion cov ntsiab lus kom tau raws li qhov kev xav tau ntawm cov kev xav tau ntawm cov kev xav tau ntawm cov khoom hluav taws xob siab.
Tiam sis kev loj hlob
Nrog rau kev txhim kho ntawm high - Technical Industries, qhov kev thov rau qhov kev ua tib yam silica micropower tseem loj hlob. Nyob rau hauv lub neej yav tom ntej, nws cov thev naus laus zis ntau lawm yuav ua rau cov ntaub ntawv sib tsoo ultras Nyob rau tib lub sijhawm, kev txhawb nqa ntawm cov txheej txheem ib puag ncig zoo tshaj plaws kuj tseem yuav dhau los ua qhov tseem ceeb ntawm kev txhim kho rau kev lag luam.
Hauv cov ntsiab lus, zoo tib yam silica micropowder, vim nws cov khoom siv lub cev thiab tshuaj lom neeg muaj kev pheej hmoo siab, uas yog siv tau thev naus laus zis thev naus laus zis.
