Mavuto azaumoyo nthawi zonse amakhala pachiwopsezo chachikulu chobisika kwa anthu.Monga mayi woyembekezera, chofunika kwambiri ndi kukonzekera zofunika za tsiku ndi tsiku kuti mwana adzabadwe pambuyo pake.Kodi mwasankha zinthu zonse za ana?mchere wa silicone, silikoni yopangidwa ndi chiyani? Kodi ndiyotetezeka kugwiritsa ntchito?

Silicone teether imapangidwa ndi gelisi ya silika ya chakudya, yomwe ilibe bisphenol A, ndipo sichitha kusweka, kung'amba mphamvu, kulimba mtima, kukana chikasu, kukalamba kutentha komanso kukana nyengo.

Nthawi zambiri, silika gel osakaniza amatha kugawidwa mu organic silika gel ndi inorganic silica gel osakaniza malinga ndi katundu ndi zigawo zikuluzikulu.

Inorganic silika gel osakaniza

Inorganic silika gel osakaniza ndi mtundu wa zinthu kwambiri yogwira adsorption, amene nthawi zambiri anakonza ndi anachita sodium silicate ndi asidi sulfuric ndi mndandanda wa pambuyo mankhwala njira monga ukalamba ndi asidi thovu.Silica gel osakaniza ndi amorphous mankhwala, ndi mankhwala ake formula ndi mSiO2.NH2O.Isoluble m'madzi ndi zosungunulira zilizonse, zopanda poizoni, zopanda pake, mankhwala amakhala okhazikika, kupatula maziko amphamvu, hydrofluoric acid ndipo samakhudzidwa ndi zinthu zilizonse.

Mitundu yosiyanasiyana ya gelisi ya silika imakhala ndi mapangidwe osiyanasiyana a microporous chifukwa cha njira zosiyanasiyana zopangira.Chigawo cha mankhwala ndi mawonekedwe a thupi la silika gel osakaniza amatsimikizira kuti ali ndi zinthu zina zambiri zofanana ndizovuta kuti zisinthe makhalidwe ake: ntchito yapamwamba ya adsorption, kutentha kwa kutentha, kukhazikika kwa mankhwala, ali ndi mphamvu zamakina apamwamba, etc., kunyumba ntchito monga desiccant, chinyezi regulator, deodorant, etc.Industry monga mafuta hydrocarbon decolorization wothandizira, chothandizira chonyamulira, variable kuthamanga adsorbent; Zabwino kulekana mankhwala ndi kuyeretsa wothandizira, mowa stabilizer, utoto thickener, otsukira mano mikangano. wothandizira, wozimitsa.

Silicone ya organic

Silicone ndi mtundu wa organosilicon pawiri, amatanthauza lili Si-C chomangira, ndipo osachepera gulu organic chikugwirizana mwachindunji ndi maatomu pakachitsulo pawiri, mwambo nthawi zambiri anthu kudzera mpweya, sulfure, nayitrogeni, etc. polysiloxane, yomwe imapangidwa ndi silicon oxygen bond (-si-o-si -) monga mafupa, ndiyo yochuluka kwambiri, yophunzira kwambiri komanso yogwiritsidwa ntchito kwambiri yamagulu a organosilicone, omwe amawerengera oposa 90% a mlingo wonse.

Organosilicon imagawidwa m'magulu anayi: mphira wa silikoni, utomoni wa silikoni, mafuta a silikoni ndi wothandizira wa silane.

Waukulu chigawo chimodzi cha silika gel osakaniza ndi silika woipa, amene ali khola mankhwala katundu ndipo alibe kutentha.Silika gel osakaniza ndi mtundu wa amorphous pakachitsulo woipa, ayenera kulamulidwa msonkhano fumbi zili zosaposa 10 mg/m3, ayenera kulimbikitsa mpweya wotuluka. , opareshoni valani chigoba.

Gelisi ya silika imakhala ndi mphamvu yowonongeka, imatha kutulutsa khungu la munthu, choncho, opaleshoni iyenera kuvala zovala zabwino za ntchito.Ngati silikoni ilowa m'maso, yambani ndi madzi ambiri ndikuwona dokotala mwamsanga. .

Blue silika gel osakaniza lili pang`ono cobalt mankhwala enaake, ali lingathe kawopsedwe, ayenera kupewa kukhudzana ndi chakudya ndi pokoka mpweya m`kamwa, monga poyizoni zochitika ayenera yomweyo kupeza chithandizo chamankhwala.

Silika gel osakaniza pogwiritsira ntchito ndondomekoyi chifukwa cha kutsekemera kwa nthunzi ya madzi kapena zinthu zina zapakatikati, mphamvu ya adsorption itachepa, ikhoza kugwiritsidwanso ntchito pambuyo pa kubadwanso.
