Kodi chingamu cha cellulose ndi chiyani?

Cellulose chingamu, yomwe imadziwikanso kuti carboxymethylcellulose (CMC), ndi polima wosungunuka m'madzi wopangidwa kuchokera ku cellulose, polima wachilengedwe yemwe amapanga gawo lalikulu la makoma a cellulose. Chingamu cha cellulose chimagwiritsidwa ntchito kwambiri m'mafakitale azakudya, azamankhwala, komanso osamalira anthu ngati chowonjezera, chokhazikika, komanso chomangira chifukwa cha mawonekedwe ake apadera.

Ma cellulose chingamu amapangidwa ndi kusintha kwa cellulose pogwiritsa ntchito sodium hydroxide ndi monochloroacetic acid. Zotsatira zake ndi mchere wa sodium wa carboxymethylcellulose, womwe umasungunuka m'madzi, anionic polima yomwe imatha kupanga mawonekedwe ngati gel ikathiridwa madzi.

Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi chingamu cha cellulose ndi monga chowonjezera muzakudya. Itha kugwiritsidwa ntchito pazakudya zosiyanasiyana, kuphatikiza sosi, mavalidwe, zowotcha, ndi ayisikilimu. Muzochita izi, chingamu cha cellulose chimagwira ntchito ngati thickening powonjezera kukhuthala kwa chinthucho, kukonza kapangidwe kake, ndikuletsa kulekanitsa kwa zosakaniza. Cellulose chingamu nthawi zambiri amagwiritsidwa ntchito limodzi ndi zokhuthala zina, monga xanthan chingamu kapena guar chingamu, kuti akwaniritsekapangidwe kake ndi kukhazikika.

Cellulose chingamu imagwiritsidwanso ntchito ngati chokhazikika muzakudya. Itha kuletsa mapangidwe a ayezi muzakudya zowuma, kupewa kulekanitsa kwa zosakaniza mu emulsion, ndikuletsa kusungunuka kwa zakumwa. Kuphatikiza apo, chingamu cha cellulose chingagwiritsidwe ntchito ngati chomangira muzakudya za nyama, monga soseji ndi nyama yanyama, kuti muchepetse kapangidwe kake ndikuchepetsa mafuta.

M'makampani opanga mankhwala, chingamu cha cellulose chimagwiritsidwa ntchito ngati chomangira pamapiritsi kuti agwire zosakaniza zogwira ntchito pamodzi ndikuwongolera kupsinjika kwa ufa. Chingamu cha cellulose chimagwiritsidwanso ntchito ngati chophatikizira m'mapiritsi ndi makapisozi kuti athandizire kuwonongeka kwa piritsi kapena kapisozi m'mimba.

M'makampani osamalira anthu, chingamu cha cellulose chimagwiritsidwa ntchito ngati thickener ndi stabilizer muzinthu zosiyanasiyana, kuphatikiza ma shampoos, ma conditioner, ndi mafuta odzola. Itha kugwiritsidwanso ntchito ngati chopangira mafilimu muzopaka tsitsi ndi zinthu zina zamakongoletsedwe.

Ubwino umodzi wa chingamu cha cellulose ndikuti siwowopsa komanso si allergenic, ndikupangitsa kuti ikhale yotetezeka kuti igwiritsidwe ntchito pamitundu yambiri. Kuphatikiza apo, chingamu cha cellulose chimakhala chokhazikika pamitundu yambiri ya pH ndipo sichikhudzidwa ndi kutentha kapena kuzizira, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.

Cellulose chingamu ndi chinthu chogwirizana ndi chilengedwe. Zimachokera kuzinthu zongowonjezedwanso, ndipo njira yopangira ndi yocheperako mphamvu. Chingamu cha cellulose chimathanso kuwonongeka ndipo chimatha kuphwanyidwa ndi chilengedwe.

Ngakhale kuti ali ndi ubwino wambiri, pali zolepheretsa kugwiritsa ntchito chingamu cha cellulose. Chimodzi mwazolepheretsa chachikulu ndi chakuti zimakhala zovuta kumwazikana m'madzi, zomwe zingayambitse kugwedeza ndi kusagwirizana. Kuphatikiza apo, chingamu cha cellulose chikhoza kusokoneza kakomedwe ndi mkamwa mwazakudya zina, makamaka pazakudya zambiri.
