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 chilinganizo ake mankhwala ndi mSiO2.NH2O.Insoluble m'madzi ndi zosungunulira zilizonse, mankhwala amphamvu, osakhala ndi poizoni, hydrofluoric acid ndi zosungunulira zilizonse, zopanda poizoni, zopanda poizoni, ndi zotumphukira za acidic. palibe chochita ndi zinthu zilizonse.

Mitundu yosiyanasiyana ya gelisi ya silika ili ndi mapangidwe osiyanasiyana a microporous chifukwa cha njira zawo zopangira zosiyana.Chigawo cha mankhwala ndi mawonekedwe a thupi la silika gel osakaniza amatsimikizira kuti ali ndi zinthu zina zambiri zofanana ndizovuta kuti zisinthe makhalidwe: kutsekemera kwapamwamba, kutentha kwa kutentha, kukhazikika kwa mankhwala, kumakhala ndi mphamvu zamakina, etc. chothandizira chonyamulira, chosinthira kupanikizika kwa adsorbent; Njira yabwino yolekanitsa mankhwala ndi kuyeretsa, chokhazikika chamowa, chokhuthala utoto, mankhwala otsukira mano, wothandizira kuzimitsa.

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. mankhwala a organosilicone, owerengera oposa 90% ya 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 utsi mpweya, ntchito kuvala chigoba.

Gelisi ya silika imakhala ndi mphamvu yowonongeka kwambiri, imatha kutulutsa zowuma pakhungu la munthu, choncho, opaleshoni iyenera kuvala zovala zabwino za ntchito.Ngati silicone 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.
