Chidziwitso cha sodium carboxymethylcellulose

Sodium carboxymethylcellulose (NaCMC) ndi yosunthika komanso yosunthika yochokera ku cellulose yomwe imapezeka m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera. Chigawochi chimachokera ku cellulose, polima yachilengedwe yomwe imapezeka m'makoma a cellulose. Sodium carboxymethyl cellulose imapangidwa pochita cellulose ndi sodium monochloroacetate ndikuyisokoneza. Zotsatira zake zimakhala ndi zinthu zingapo zofunika, zomwe zimawapangitsa kukhala ofunika muzakudya ndi zakumwa, mankhwala, zodzoladzola, nsalu ndi zina zambiri.

Kapangidwe ndi kapangidwe kake:

Sodium carboxymethyl cellulose ndi polima wosungunuka m'madzi wokhala ndi mzere wozungulira. Msana wa cellulose umasinthidwa ndi magulu a carboxymethyl oyambitsidwa ndi etherification. Digiri ya m'malo (DS) imatanthawuza kuchuluka kwamagulu a carboxymethyl pagawo la anhydroglucose mu unyolo wa cellulose. DS imakhudza kwambiri thupi ndi mankhwala a NaCMC.

Njira yopanga:

Kupanga sodium carboxymethylcellulose kumaphatikizapo njira zingapo. Cellulose nthawi zambiri imachokera ku nkhuni kapena thonje ndipo imakonzedwa kuti ichotse zonyansa. Kenako imakhudzidwa ndi sodium monochloroacetate pansi pamikhalidwe yamchere kuyambitsa gulu la carboxymethyl. Chotsatiracho sichimasinthidwa kuti chipeze mchere wa sodium carboxymethylcellulose.

Thupi ndi mankhwala katundu:

Kusungunuka: NaCMC imasungunuka kwambiri m'madzi, kupanga yankho lomveka bwino komanso lowoneka bwino. Kusungunuka uku ndi chizindikiro chofunikira kwambiri pakugwiritsa ntchito kwake m'mafakitale osiyanasiyana.

Viscosity: Kukhuthala kwa sodium carboxymethylcellulose solution kumatha kusinthidwa ndikuwongolera kuchuluka kwa m'malo ndi kukhazikika. Katunduyu amapangitsa kuti ikhale yoyenera kugwiritsa ntchito zomwe zimafunikira kukhuthala kapena gelling.

Kukhazikika: NaCMC imakhalabe yokhazikika pamitundu yambiri ya pH, yomwe imakulitsa kusinthasintha kwake pamapangidwe osiyanasiyana.

Kupanga Mafilimu: Ili ndi zinthu zopangira mafilimu ndipo imatha kugwiritsidwa ntchito popanga mafilimu ndi zokutira m'njira zosiyanasiyana.

ntchito:

Makampani a Chakudya ndi Chakumwa:

Thickening agent:NaCMC imagwiritsidwa ntchito ngati chowonjezera pazogulitsa monga ma sosi, mavalidwe ndi zakumwa.

Stabilizer: Yabayailizes emulsions ndi kuyimitsidwa muzinthu monga ayisikilimu ndi mavalidwe a saladi.

Kusintha kwa Maonekedwe: NaCMC imapereka mawonekedwe ofunikira ku zakudya, kuwongolera zonse.mankhwala:

Zomangira: Zogwiritsidwa ntchitomonga zomangira pamapiritsi kuti zitsimikizire kukhulupirika kwa mapiritsi.

Viscosity modifier: imasintha ma viscosity wa kukonzekera kwamadzimadzi kuti athandizire kuperekera mankhwala.

Zodzoladzola ndi chisamaliro chamunthu:

Stabilizers: Ntchito kukhazikika emulsions mu zonona ndi lotions.
Thickeners: Wonjezerani kukhuthala kwa shampu, mankhwala otsukira mano ndi zinthu zina zosamalira munthu.
nsalu:

Sizing agent: amagwiritsidwa ntchito popanga nsalu kuti azitha kulimba komanso kusalala kwa ulusi panthawi yoluka.

Pula yosindikizira: Imagwira ntchito ngati thickener ndi rheology modifier mu nsalu yosindikiza phala.
Makampani a Mafuta ndi Gasi:

Kubowola madzimadzi: NaCMC ndiamagwiritsidwa ntchito ngati tackifier pobowola madzi kuti apititse patsogolo mawonekedwe ake a rheological.

Makampani opanga mapepala:

Coating agent: amagwiritsidwa ntchito popaka mapepala kuti apititse patsogolo zinthu za pamwamba.
mafakitale ena:

Chithandizo cha Madzi: Chimagwiritsidwa ntchito pochiza madzi chifukwa cha flocculation.

Detergent: Imagwira ntchito ngati stabilizer muzinthu zina zotsukira.

Chitetezo ndi malamulo:

Sodium carboxymethylcellulose nthawi zambiri imadziwika kuti ndi yotetezeka (GRAS) yogwiritsidwa ntchito pazakudya ndi mankhwala. Imatsatira miyezo yoyendetsera ndi zomwe mabungwe angapo, kuphatikiza US Food and Drug Administration (FDA) ndi European Food Safety Authority (EFSA).

Sodium carboxymethyl cellulose ndi polymer yogwira ntchito zambiri yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana. Kuphatikizika kwake kwapadera kwa solubility, control viscosity control, kukhazikika ndi kupanga mafilimu kumapangitsa kuti ikhale yofunika kwambiri muzojambula zosiyanasiyana. Pamene makampaniwa akupitilirabe kusinthika, kufunikira kwa sodium carboxymethylcellulose kuyenera kupitilirabe chifukwa cha kusinthasintha kwake komanso kuthandizira pakupititsa patsogolo magwiridwe antchito azinthu zosiyanasiyana.
