Mavuto azaumoyo nthawi zonse amakhala ngozi yaikulu kwambiri kwa anthu. Monga mayi woyembekezera, chofunika kwambiri ndikukonzekera zofunikira za tsiku ndi tsiku kuti mwana abadwe motsatira. Kodi mwasankha zinthu zonse za mwana? Kodi ndi mtundu wanji wa zinthu zabwino kwambiri, tikadamva za izo?teether ya silikoniKodi silicone imapangidwa ndi chiyani? Kodi ndi yotetezeka kugwiritsa ntchito?

Chovala cha silicone teether chimapangidwa ndi silika gel yopangidwa ndi chakudya, yomwe ilibe bisphenol A, ndipo siithyoka, siingang'ambe mphamvu, siingapirire, siingapirire chikasu, ikalambe kutentha komanso siingapirire nyengo.

BPA yopanda poizoni, yofewa yosalowa madzi, yopanda poizoni komanso yofundamagolovesi a silicone oteteza mano a ana

Kawirikawiri, silika gel imatha kugawidwa m'magulu awiri: organic silica gel ndi inorganic silica gel malinga ndi makhalidwe ake ndi zigawo zake.

Gel ya silika yopanda chilengedwe

Geli ya silica yopanda organic ndi mtundu wa zinthu zokhutiritsa kwambiri, zomwe nthawi zambiri zimakonzedwa ndi momwe sodium silicate imagwirira ntchito ndi sulfuric acid komanso njira zingapo zochizira pambuyo pake monga ukalamba ndi mabulovu a asidi. Geli ya silica ndi chinthu chosasinthika, ndipo njira yake ya mankhwala ndi mSiO2.NH2O. Sisungunuka m'madzi ndipo chilichonse chosungunulira, chopanda poizoni, sichimakoma, ndi chokhazikika, kupatula maziko olimba, hydrofluoric acid ndipo palibe chomwe chimachitika ndi zinthu zilizonse.

Mitundu yosiyanasiyana ya silika gel ili ndi mapangidwe osiyanasiyana a microporous chifukwa cha njira zawo zosiyanasiyana zopangira. Gawo la mankhwala ndi kapangidwe kake ka silika gel limatsimikizira kuti lili ndi zinthu zina zambiri zofanana ndizovuta kusintha mawonekedwe ake: magwiridwe antchito okwera a adsorption, kukhazikika kwa kutentha, kukhazikika kwa mankhwala, mphamvu yayikulu yamakina, ndi zina zotero, kunyumba komwe kumagwiritsidwa ntchito ngati desiccant, chowongolera chinyezi, deodorant, ndi zina zotero. Makampani monga mafuta hydrocarbon decolorization agent, chonyamulira chothandizira, chotsatsira mphamvu yosinthasintha; Chothandizira kulekanitsa ndi kuyeretsa mankhwala, chokhazikika cha mowa, chokhuthala utoto, chothandizira mano otsukira mano, chothandizira kuzimitsa.

Silikoni yachilengedwe

Silicone ndi mtundu wa organosilicon compound, yomwe imatanthauza kuti ili ndi Si-C bond, ndipo gulu limodzi la organic limalumikizidwa mwachindunji ndi maatomu a silicon a composition, ndipo nthawi zambiri amapangidwa kudzera mu mpweya, sulfure, nayitrogeni, ndi zina zotero. Pakati pawo, polysiloxane, yomwe imapangidwa ndi silicon oxygen bond (-si-o-si -) monga chigoba, ndi mtundu wa organosilicone compounds wochuluka kwambiri, wophunziridwa kwambiri komanso wogwiritsidwa ntchito kwambiri, womwe umapanga zoposa 90% ya mlingo wonse.

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

Gawo lalikulu la silika gel ndi silica dioxide, yomwe ili ndi mphamvu zokhazikika za mankhwala ndipo siyaka. Silika gel ndi mtundu wa silicon dioxide wosasinthika, iyenera kulamulidwa ndi fumbi la workshop losapitirira 10 mg/m3, iyenera kulimbitsa mpweya wotulutsa utsi, komanso kugwiritsa ntchito chigoba.

Silika gel ili ndi mphamvu yokwanira yothira madzi, imatha kuuma pakhungu la munthu, chifukwa chake, opaleshoniyo iyenera kuvala zovala zabwino zogwirira ntchito. Ngati silicone yalowa m'diso, tsukani ndi madzi ambiri ndikuwonana ndi dokotala mwamsanga.

Gel wabuluu wa silica uli ndi cobalt chloride pang'ono, ukhoza kukhala ndi poizoni, ndipo uyenera kupewa kukhudzana ndi chakudya ndi kupuma mkamwa, monga poizoni, uyenera kupita kuchipatala nthawi yomweyo.

Silika gel pogwiritsa ntchito njira imeneyi chifukwa cha kulowetsedwa kwa nthunzi ya madzi kapena zinthu zina zachilengedwe m'malo osungira madzi, mphamvu ya kulowetsedwa kwa madzi yachepa, ndipo ikhoza kugwiritsidwanso ntchito pambuyo pokonzanso.
