Matambudziko ehutano anogara ari njodzi huru yakavanzika kuvanhu. Saamai vane pamuviri, chinhu chinonyanya kukosha kugadzirira zvinodiwa zuva nezuva kuti mwana azvarwe.silicone teether, chii chinonzi silicone? Yakachengeteka here kushandisa?

Silicone teether inogadzirwa ne-chikafu-giredhi silica gel, iyo isina bisphenol A, uye isingatyoke, kubvarura simba, kusimba, kuramba kutsvuka, kupisa kuchembera uye kusagadzikana kwemamiriro ekunze.

Kazhinji kutaura, silica gel inogona kupatsanurwa kuita organic silica gel uye inorganic silica gel zvichienderana neayo midziyo uye zvikamu.

Inorganic silica gel

Inorganic silica gel imhando yezvakanyanya kushanda adsorption material, iyo inowanzogadzirirwa nekuita kwe sodium silicate ne sulfuric acid uye mutsara wemashure ekurapa maitiro akadai sekukwegura uye acid bubbles.Silica gel is amorphous substance, uye chimiro chayo chemakemikari is mSiO2.NH2O.Isingagadziriswi mumvura uye chero ipi zvayo inonyungudika, isingasviki, hydrooric acid, isina kusimba uye inokonzera kunyunguduka. hapana kuita nechero zvinhu.

Mhando dzakasiyana dzesilica gel dzine maitiro akasiyana-siyana e-microporous nekuda kwemaitiro avo akasiyana-siyana ekugadzira.Chikamu chemakemikari uye chimiro chemuviri chesilica gel chinotarisa kuti ine zvimwe zvinhu zvakawanda zvakafanana zvakaoma kutsiva maitiro: high adsorption performance, thermal stability, chemical stability, ine high mechanical simba, nezvimwewo, imba inoshandiswa se desiccant, humidity regulator, deodorant mafuta, deodorant, etc. catalyst carrier, variable pressure adsorbent; Yakanaka makemikari kupatsanurwa uye yekuchenesa mumiririri, doro stabilizer, pendi thickener, mazino friction agent, extinction agent.

Organic silicone

Silicone imhando ye organosilicon compound, inoreva ine Si-C bond, uye kanenge rimwe organic boka rakabatana zvakananga nemaatomu esilicon emukomboni, tsika inowanzova iyo kuburikidza neokisijeni, sarufa, nitrogen, nezvimwe. Pakati pavo, polysiloxane, inoumbwa nesilicon okisijeni bond (-si-o-si -) ndiyo inonyanya kushandiswa uye inonyanya kushandiswa mhando organosilicone makomisheni, anoverengera inopfuura 90% yeiyo yakazara dosage.

Organosilicon inonyanya kukamurwa kuita zvikamu zvina: silicone rabha, silicone resin, mafuta esilicone uye silane coupling agent.

Chikamu chikuru chesilica gel is silica dioxide, iyo ine yakagadzikana makemikari ehupfumi uye haipisi.Silica gel imhando yeamorphous silicon dioxide, inofanira kudzorwa workshop guruva zvinyorwa zvisingasviki 10 mg / m3, inoda kusimbisa mhepo inopera, kushanda kupfeka mask.

Silica gel ine simba rakasimba rekudsorption, rinogona kuunza kuoma kwakaoma paganda remunhu, saka, kushanda kunofanira kupfeka zvipfeko zvakanaka zvebasa.Kana iyo silicone inopinda muziso, simesa nemvura yakawanda uye ona chiremba kurapwa nokukurumidza.

Bhuruu silica gel ine shoma cobalt chloride, ane zvinogona toxicity, vanofanira kudzivisa kusangana nechikafu uye inhalation mumuromo, akadai chepfu zviitiko vanofanira pakarepo kutsvaka kurapwa.

Silica gel mukushandiswa kwemaitiro nekuda kwekushambadza kwemhute yemvura kana zvimwe organic zvinhu mukati mepakati, adsorption kugona kwakadzikira, inogona kushandiswa zvakare mushure mekuzvarwa patsva.
