Lub cev muaj zog: TOP series silica yog tsim los ntawm txoj kev los nag, cov khoom lag luam tsis raug tswj tau, los ntawm qhov sib txawv '
silica tuaj yeem tsim tau raug. Nws kuj tuaj yeem ua tau raws li qhov xav tau. TOP series silica muaj qhov ntom ntom 0.192-0.320, fusion point 1750 ℃, hollowness.
Nws muaj zoo dispersancy nyob rau hauv crude roj hmab nrog cov cuab yeej ntawm kev sib tov ceev thiab siab siv. Nws tuaj yeem siv rau hauv ntau qhov chaw, thiab nws yooj yim los ua ke nrog fibers, roj hmab thiab yas thiab lwm yam.
Silicon Dioxide muaj nyob rau hauv ob hom: Crystalline Silicon Dioxide thiab Amorphous Silica. Crystalline Silicon Dioxide, zoo li quartz, muaj cov qauv zoo atomic, uas ua rau nws muaj zog hardness thiab zoo heev optical zog. Nws yog pob tshab rau ntau hom wavelengths, ua rau nws muaj txiaj ntsig zoo hauv kev siv kho qhov muag.
Amorphous Silica, ntawm qhov tod tes, tsis muaj kev txiav txim ntev ntev. Fused Silica, ib hom amorphous silica, yog tsim los ntawm melting quartz thiab tsis tshua muaj thermal expansion, ua rau nws zoo tagnrho rau high-precision daim ntaub ntawv. Silicon Dioxide Nanoparticles muaj cov khoom tshwj xeeb vim lawv qhov me me, xws li qhov loj ntawm qhov loj - mus rau - ntim piv, uas tuaj yeem txhim kho cov tshuaj reactivity hauv cov txheej txheem tshuaj.
Silica Powder thiab Silicon Dioxide Powder tuaj hauv ntau qhov ntau thiab tsawg thiab purities. Lawv cov ntaub ntawv lub cev tuaj yeem ua tau los ntawm cov hmoov zoo mus rau cov ntaub ntawv granular, uas tuaj yeem tsim kho raws li kev thov sib txawv.
Feem ntau yog siv barite ua cov khoom uas muaj cov khoom siv siab ntawm barium sulfate barite, thee thiab calcium chloride yog tov, thiab calcined kom tau barium chloride, cov tshuaj tiv thaiv yog raws li nram no:
BaSO4 + 4C + CaCl2 → BaCl2 + CaS + 4CO ↑.
Kev tsim cov txheej txheem ntawm Barium Chloride anhydrous: Barium chloride dihydrate yog rhuab mus rau saum toj 150 ℃ los ntawm lub cev qhuav dej kom tau txais cov khoom lag luam barium chloride anhydrous. nws
BaCl2 • 2H2O [△] → BaCl2 + 2H2O
Barium chloride kuj tseem tuaj yeem npaj los ntawm barium hydroxide lossis barium carbonate, tom kawg tau pom zoo li cov ntxhia "Witherite". Cov ntsev yooj yim no cuam tshuam los muab hydrated barium chloride. Ntawm qhov ntsuas kev lag luam, nws tau npaj los ntawm txheej txheem ob kauj ruam

* TOP25 hom Silica, uas belongs rau Alkaline Dawb Carbon Black, tuaj yeem siv los ua tus neeg sawv cev ntxiv rau hauv cov khoom siv roj hmab butyl xws li roj hmab, cov ntaub nplaum, cov roj hmab foob thiab lwm yam khoom siv roj hmab. Nws tuaj yeem txhim kho lub cev ntawm cov roj hmab xws li lub zog, hardness, lub zog tsim kua muag, elasticity thiab hnav tsis kam, ua rau cov khoom siv roj hmab ruaj khov thiab txhim kho lawv cov kev ua tau zoo thiab kev ntseeg tau.
Muaj ob txoj hauv kev los tsim Silicon Dioxide: natural extraction thiab synthetic method.
Ntuj Extraction
Ntuj quartz yog mined los ntawm lub ntiaj teb. Tom qab kev rho tawm, nws tau dhau los ua cov txheej txheem xws li crushing, sib tsoo, thiab purification kom tau txais siab-purity Silicon Dioxide. Cov txheej txheem no tsuas yog tsim cov ntaub ntawv crystalline ntawm silicon dioxide.
Synthetic Methods
Synthetic Silicon Dioxide yog tsim los ntawm cov tshuaj tiv thaiv. Ib txoj hauv kev yog cov txheej txheem nag lossis daus, qhov twg sodium silicate reacts nrog cov kua qaub los tsim cov silica gel, uas tom qab ntawd qhuav thiab milled los tsim silica hmoov. Lwm txoj kev yog cov txheej txheem fumed silica, uas koom nrog qhov kub siab hydrolysis ntawm silicon tetrachloride hauv cov pa oxygen - hydrogen nplaim kom tsim tau zoo heev thiab siab - purity amorphous silica.

Hauv Kev Lag Luam Tire thiab Roj Hmab
Silicon Dioxide hauv Log Tsheb thiab Silicon Dioxide hauv Rubber ua lub luag haujlwm tseem ceeb. Silica Filler yog ntxiv rau cov roj hmab sib txuas los txhim kho lub log tsheb. Nws txhim kho traction, txo cov dov tsis kam, thiab txhim kho roj efficiency. Qhov no ua rau cov log tsheb muaj kev nyab xeeb thiab zoo ib puag ncig.
Hauv kev lag luam Electronics
Silicon Dioxide hauv Electronics yog siv los ua cov khoom siv insulating hauv cov khoom siv semiconductor. Nws lub zog dielectric siab thiab thermal stability ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev cais cov khoom sib txawv hauv kev sib xyaw ua ke. Nws kuj tseem pab tiv thaiv cov khoom siv hluav taws xob los ntawm ib puag ncig xws li ya raws thiab plua plav.
Hauv Kev Lag Luam Khoom Noj
Silica hauv zaub mov yog siv los ua tus neeg sawv cev tiv thaiv kab mob. Nws tiv thaiv cov khoom noj khoom haus los ntawm clumping ua ke, kom ntseeg tau ib tug dawb - ntws sib xws. Nws yog feem ntau siv rau hauv cov khoom siv hmoov nplej xws li txuj lom, hmoov nplej, thiab kas fes creamer.
Hauv Kev Lag Luam Xim
Silica hauv Paints yog siv los txhim kho cov kav ntev thiab khawb tsis kam ntawm cov xim pleev xim. Nws tseem tuaj yeem txhim kho qhov gloss thiab zoo li ntawm cov xim, ua rau nws txaus siab rau cov neeg siv khoom.
Hauv Pharmaceutical Industry
Silicon Dioxide hauv Pharmaceuticals yog siv los ua glidant hauv kev tsim cov ntsiav tshuaj. Nws pab cov ntsiav tshuaj kom ntws zoo thaum lub sijhawm tsim khoom, ua kom cov ntsiav tshuaj hnyav thiab zoo.
