Aerosil (los yog silicon dioxide) yog ib qho translucent (muaj me ntsis bluish tint), lub teeb thiab friable hmoov tsis muaj aroma lossis saj. Nws yog tau los ntawm hydrolysis ntawm silicon nyob rau hauv ib tug nplaim taws ntawm detonating gas (ib tug sib tov ntawm hydrogen thiab oxygen raws li ib tug tshwm sim ntawm combustion). Lub resulting tshuaj tsis sib tov nrog dej. Nws belongs rau cov pab pawg neeg ntawm hydrophobic tshuaj, vim nws precipitates tsis interacting nrog cov kua, tsis muaj nws. Ntawm no, hauv ib lub ntsiab lus, yog Aerosil. Tom ntej no, peb yuav tau paub ntau ntxiv txog cov khoom no thiab nrhiav seb qhov twg ntawm nws daim ntawv thov.

Lub cev thiab tshuaj lom neeg

Nyob rau hauv nws cov qauv, cov tshuaj Aerosil muaj spherical hais, nrog ib txoj kab uas hla ntawm 7 mus rau 40 nanometers. Yog muaj peev xwm muab tau tag nrho cov khoom nyob rau hauv ib txoj saw, ces qhov ntev no yuav txaus kom tau los ntawm lub ntiaj teb mus rau lub hli 17 zaug.

Tau txais silicon aerosil thawj zaug tau sau npe hauv xyoo 1942, thiab txij li ntawd los nws qhov kev siv tau raug pom zoo ntawm kev lag luam. Thiab qhov no yog vim muaj ntau yam kev siv ntawm cov khoom no.

Tau txais silicon dioxide yog tus cwj pwm los ntawm qhov sib txawvqhov loj me ntawm cov khoom zoo, nyob ntawm cov xwm txheej ntawm cov tshuaj tiv thaiv. Yog li ntawd, physicochemical thaj chaw ntawm cov tshuaj hloov pauv, thiab nws tau cim nrog ntau tus lej tom qab nws lub npe tseem ceeb. Yog li ntawd, tom qab lo lus "aerosil" yeej ib txwm muaj tus lej qhia qhov loj ntawm nws cov khoom.

Nyob rau sab nrauv ntawm lub tom kawg muaj pawg siloxane thiab silanol, uas ua rau Aerosil inert rau dej. Vim li no, nws yog hydrophobic thiab muaj tshuaj lom neeg muaj zog rau ntau yam reagents.

Scope of Aerosil

Raws li tau hais dhau los, nws qhov dav dav thiab cuam tshuam rau thaj chaw hauv qab no:

• tsim - tsim cov silicates, sealants, varnishes, luam ntawv inks, insulating cov ntaub ntawv, thiab lwm yam.;
• tshuaj - hloov cov kua rau hauv cov hmoov tsis muaj dej, ua cov tshuaj, ntsiav tshuaj, tshuaj aerosols, thiab lwm yam.
• tshuaj pleev ib ce - pleev xim, pleev, hmoov, pastes, thiab lwm yam.;
• food - as supplements.

Nws yog dab tsi - aerosil, koj tuaj yeem tham tau ntev heev, tab sis saum toj no yog thaj chaw tseem ceeb ntawm kev siv cov tshuaj no.

Kev tsim kho

Hauv kev tsim kho kev lag luam, cov khoom siv silicon txhim kho lub cev thiab cov khoom siv kho tshuab. Nws ua kom lub zog, elasticity, hnav tsis kam thiab kub tsis kam ntawm cov ntaub ntawv, ua haujlwm zoo heev li cov thickener thiab ntau ntxiv. Clear varnishes rauRaws li polyester resins kuj tau ua tsaug rau cov khoom no.

Aerosil txhim kho cov khoom siv ntawm cov khoom yas, muaj cov khoom zoo heev insulating (tsis tshua muaj thermal conductivity), yog li nws yog dav siv hauv cov ntaub ntawv uas insulate cables. Ntxiv rau qhov saum toj no, silicon dioxide (aerosil) yog siv los ua cov xim stabilizer hauv kev tiv thaiv corrosion ntawm hlau coatings.

Txog tam sim no, silicon dioxide tsuas yog ib qho sib xyaw tshwj xeeb. Tab sis nws yog dab tsi - aerosil, hais txog kev nyab xeeb rau tib neeg? Ib qho zoo ntxiv rau txhua yam yog nws qhov hluav taws kub kev nyab xeeb thiab tsis muaj tshuaj lom. Cov tshuaj no tsis muaj teeb meem rau tib neeg kev noj qab haus huv lossis lwm yam tsiaj nyob.

siv kho mob

Thiab Aerosil yog dab tsi hauv cov tshuaj thiab tshuaj? Nws hloov tawm hais tias colloidal silicon dioxide muaj sorption zoo nyob rau hauv kev sib raug zoo rau enzymes, antigens, cov ntaub so ntswg lwj cov khoom, ntau yam co toxins, allergens, microorganisms, thiab ntau ntxiv. Yog li ntawd, nws yog siv topically yog hais tias tsim nyog nyob rau hauv lub regeneration ntawm cov ntaub so ntswg thiab ntawm daim tawv nqaij (xws li purulent-inflammatory etiology), raws li zoo raws li nyob rau hauv cov ntaub ntawv ntawm lom lom, plab hnyuv kab mob, tsis haum cov tsos mob, gastrointestinal chim siab.

Cov tshuaj no tsis tawg hauv lub cev, tsis nqus los ntawm cov hnyuv thiab tawm tawm tsis hloov pauv. Tab sis nws tsis ua rau lub plab mucosa thiab tshem tawm toxins.

Tsis tas li, kev teem sijhawm ntawm cov tshuaj uas muaj aerosil tuaj yeem ua tau yog tias muaj kev ua txhaum cai hauv cov txheej txheem metabolictshuaj, deterioration ntawm daim siab thiab ob lub raum. Nws kuj tiv tau zoo nrog kev tso tawm ntawm uric acid, uas cuam tshuam tsis zoo rau kev noj qab haus huv ntawm cov pob qij txha.

Peb yuav tsum tsis txhob hnov qab txog qhov zoo ntawm aerosil. Nws yog dab tsi rau tus txiv neej? Qhov no yog kev tshem tawm cov quav hniav, ua tsaug rau kev ntxuav lub qhov ncauj nrog cov tshuaj txhuam hniav.

Nyob rau hauv xaus txog cov khoom tshwj xeeb

Hnub no peb nqa daim ntaub thaiv me ntsis ntawm cov khoom tshwj xeeb hu ua silicon dioxide. Thiab peb cia siab tias koj tuaj yeem teb nws yog dab tsi - aerosil. Txawm hais tias nws yuav nyuaj rau ua qhov no, txij li qhov no yog ib qho cuab yeej siv thoob ntiaj teb, qhov uas tsuas yog qhov loj heev.

Los ntawm qhov muaj txiaj ntsig - nws muaj kev nyab xeeb thiab tsis muaj mob rau tib neeg, thiab nws cov khoom muaj txiaj ntsig zoo tsis tuaj yeem tab sis cov kws tshaj lij txaus siab. Ntawm qhov ntsuas kev lag luam, nws yuav siv txuas ntxiv mus, thiab nws cov peev txheej tsuas yog loj hlob txhua xyoo.
