Sodium carboxymethyl cellulosendi anionic cellulose ether yokhala ndi ufa wonyezimira wonyezimira kapena wachikasu pang'ono kapena ufa woyera m'mawonekedwe, wopanda fungo, wosakoma komanso wopanda poizoni; mosavuta kusungunuka m'madzi ozizira kapena otentha kuti apange njira yowonekera ndi viscosity inayake , yankho ndilopanda ndale kapena lamchere pang'ono; osasungunuka mu zosungunulira organic monga ethanol, etha, isopropanol, acetone, etc., sungunuka mu 60% madzi munali Mowa kapena acetone solution.
Ndi hygroscopic, yokhazikika ku kuwala ndi kutentha, kukhuthala kumachepa ndi kuwonjezeka kwa kutentha, yankho limakhala lokhazikika pa PH mtengo wa 2-10, mtengo wa PH ndi wotsika kuposa 2, pali mvula yolimba, ndipo PH mtengo ndi wapamwamba kuposa 10, kukhuthala kumachepa. Kutentha kwa kutentha ndi 227 ℃, kutentha kwa carbonization ndi 252 ℃, ndipo kusagwirizana kwa 2% yamadzimadzi ndi 71mn / n.
Ichi ndi katundu wa sodium carboxymethyl cellulose, ndi yokhazikika bwanji?
Zinthu zakuthupi za sodium carboxymethyl cellulose ndizokhazikika kwambiri, motero zimakhala zoyera kapena zachikasu zokhalitsa. Zinthu zake zopanda mtundu, zopanda fungo komanso zopanda poizoni zitha kugwiritsidwa ntchito munthawi zosiyanasiyana, monga makampani azakudya, makampani opanga mankhwala, ndi zina zambiri; Panthawi imodzimodziyo, imakhala ndi kusungunuka kwabwino kwambiri ndipo imatha kusungunuka m'madzi ozizira kapena madzi otentha kuti ipange gel osakaniza, ndipo njira yothetsera vutoli ndi yopanda ndale kapena yofooka ya alkaline, kotero ingagwiritsidwe ntchito pazinthu zambiri ndikubweretsa zotsatira zabwino.
Ndi chifukwa chakuti sodium carboxymethyl cellulose imasungunuka kwambiri moti imatha kugwiritsidwa ntchito nthawi zambiri popanga komanso moyo. Zowona, mawonekedwe ake akuthupi ndi okhazikika kwambiri, ndipo mapindu omwe angabweretse adzakhala owonekera kwambiri, kutilola kusangalala ndi malingaliro osiyana.
